Answer 1

Answer:

x = 50

Step-by-step explanation:

The sum of the measures of the interior angles of a polygon of n sides is

(n - 2)180

This polygon is a quadrilateral with 4 sides. n = 4

(n - 2)180 = (4 - 2)180 = 2(180) = 360

The sum of the measures of the interior angles of the quadrilateral is 360 degrees.

We have angles of 110 deg, 2x deg, x + 10 deg, and 90 deg. We add their measures and set teh sum equal to 360. Then we solve for x.

x + 10 + 2x + 110 + 90 = 360

3x + 210 = 360

3x = 150

x = 50

Answer 2
First we ate gonna write an equation to solve for x

2x + x + 10 + 110 = 360

When we add everything it’s equal to 360 because there are two triangles in a quadrilateral and each triangle measures 180. So 2 times 180 is equal to 360.

Or to simply put it all the angles in a quadrilateral measures 180.

Ok so let’s solve the equation to find x

2x + x + 10 + 110 = 360
3x + 120 = 360
3x = 360 - 120
3x/3 = 240/3
x = 80

Miss Wan and Miss Lim left their school at 2.50 p .m and drove along the same
route to Orchard Road. Miss Wan drove at an average speed of 60 Km/h and
reache Orchard Road 30 min later. Meanwhile, Miss Lim was still 5 km away from Orchard
Road.
a) What was the Miss Lim's average speed for the whole journey?

b) What time would Miss Lim reach Orchard Road?

Answers

Answer and explanation:

a) To find the average speed of Miss Lim for the whole journey, we need to use the formula:

Average speed = Total distance ÷ Total time

Let's first calculate the total distance traveled by both Miss Wan and Miss Lim. We know that Miss Wan drove at an average speed of 60 km/h and reached Orchard Road 30 minutes later. So, the total distance traveled by her would be:

Distance = Speed × Time

Distance = 60 km/h × (30/60) h

Distance = 30 km

Now, we also know that Miss Lim was still 5 km away from Orchard Road when Miss Wan reached there. Therefore, the total distance traveled by both of them would be:

Total distance = Distance covered by Miss Wan + Distance left for Miss Lim

Total distance = 30 km + 5 km

Total distance = 35 km

Next, let's calculate the total time taken by both of them. We know that Miss Wan took 30 minutes less than Miss Lim to reach Orchard Road. So, if we assume that Miss Lim took t hours to reach Orchard Road, then Miss Wan took (t - 0.5) hours. Therefore, the total time taken by both of them would be:

Total time = Time taken by Miss Wan + Time taken by Miss Lim

Total time = (t - 0.5) h + t h

Total time = 2t - 0.5 h

Now, we can use the formula to find the average speed of Miss Lim:

Average speed = Total distance ÷ Total time

Average speed = 35 km ÷ (2t - 0.5) h

Therefore, the average speed of Miss Lim for the whole journey is 35/(2t-0.5) km/h.

b) To find out what time Miss Lim would reach Orchard Road, we can use the formula:

Time taken = Distance ÷ Speed

We know that Miss Lim was 5 km away from Orchard Road when Miss Wan reached there. Therefore, the distance left for Miss Lim to cover would be:

Distance = 5 km

We also know that Miss Lim's average speed for the whole journey is 35/(2t-0.5) km/h. Therefore, the time taken by her to cover the remaining distance of 5 km would be:

Time taken = Distance ÷ Speed

Time taken = 5 km ÷ 35/(2t-0.5) km/h

Time taken = (2t - 0.5) ÷ 7 h

Now, we need to add this time to the time when Miss Wan reached Orchard Road, which was 30 minutes past 2.50 p.m. So, the time when Miss Lim would reach Orchard Road would be:

Time = Time when Miss Wan reached Orchard Road + Time taken by Miss Lim

Time = 2.50 p.m. + 30 min + (2t - 0.5) ÷ 7 h

Simplifying this equation, we get:

Time = (14t + 11) ÷ 14 p.m.

Therefore, Miss Lim would reach Orchard Road at (14t + 11) ÷ 14 p.m.

Answer:

  a) 50 km/h

  b) 3:26 p.m.

Step-by-step explanation:

You want to know Miss Lim's average speed and arrival time at Orchard Road if Miss Wan gets there in 30 minutes at 60 km/h, starting at 2:50 pm.

Distance

The distance Miss Wan traveled is ...

  distance = speed × time

  distance = (60 km/h) × (1/2 h) = 30 km

a) Speed

In the same 30 minutes that Miss Wan traveled 30 km, Miss Lim traveled 5 km less, so 30 -5 = 25 km. Miss Lim's speed was ...

  speed = distance/time

  speed = (25 km)/(1/2 h) = 50 km/h

Assuming Miss Lim maintained that speed for the remaining 5 km, her average speed for the journey was 50 km/h.

b) Time

Miss Lim's travel time is ...

  time = distance/speed

  time = (30 km)/(50 km/h) = 3/5 h = 36 min

The clock time 36 minutes after 2:50 pm is 3:26 pm.

Miss Lim reached Orchard Road at 3:26 p.m..

a large clinical trial was designed to determine whether a certain vitamin improves the general health of adults. the investigators first identified 85 variables that measure various aspects of the general health of adults. because each adult in the clinical trial was to serve as his or her own control, the 85 variables were measured for each adult, both before taking the vitamin and after taking the vitamin for three months. the investigators then performed 85 matched-pair t-tests, one for each variable. they found statistically significant results at the 0.05 level in 2 of the variables, both in the direction of improved general health. which of the following should the investigators conclude?

Answers

The investigators should conclude (C) There is insufficient evidence that the vitamin improves the health of adults because, at the 0.05 significance level, one could easily get statistically significant results in 2 out of 85 tests just due to chance variability.

In statistical hypothesis testing, a significance level of 0.05 indicates that there is a 5% chance of obtaining a statistically significant result due to chance variability if the null hypothesis is true.

In this study, the investigators performed 85 separate tests, increasing the chance of obtaining at least one false positive result due to chance variability.

This is known as the multiple comparisons problems, and to control for this issue, the investigators should have used a correction for multiple comparisons, such as the Bonferroni correction, which would have adjusted the significance level to 0.05/85 = 0.0006.

Therefore, finding two statistically significant results out of 85 tests does not provide sufficient evidence to conclude that vitamin improves the health of adults. Further studies with larger sample sizes, corrected for multiple comparisons, and controlling for confounders, are needed to draw a valid conclusion.

Find the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0)

Answers

The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.

To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.

The slope of a line can be found using the formula:

slope = (change in y) / (change in x)

For the line containing (1,2) and (5,3), the slope is:

slope1 = (3 - 2) / (5 - 1) = 1 / 4

To find the slope of the line containing (x,4) and (3,0), we use the same formula:

slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)

Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.

So, we can set up the equation:

-1 / (1/4) = -4 / (3 - x)

Simplifying this equation:

-4 = -4 / (3 - x)

To remove the fraction, we can multiply both sides by (3 - x):

-4(3 - x) = -4

Expanding and simplifying:

-12 + 4x = -4

Adding 12 to both sides:

4x = 8

Dividing both sides by 4:

x = 2

you have 51 coins in your pocket, all dimes and quarters. You have $10.20. How many dimes and quarters do you have?

Answers

To find the number of dimes and quarters, you have 17 dimes and 34 quarters in your pocket , when there are 51 coins in your pocket.

To solve this problem, we can set up a system of equations using the given information. Let's use "d" to represent the number of dimes and "q" to represent the number of quarters.

We know that there are 51 coins in total, so we can write the equation: d + q = 51.

We also know that the total value of the coins is $10.20, which can be expressed as 10d + 25q (since dimes are worth 10 cents and quarters are worth 25 cents). So our second equation is: 10d + 25q = 1020.

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

Rearrange the first equation to solve for d: d = 51 - q.

Substitute this expression for d in the second equation: 10(51 - q) + 25q = 1020.

Simplify and solve for q: 510 - 10q + 25q = 1020.

Combine like terms: 15q = 510.

Divide both sides by 15: q = 34.

Now substitute this value back into the first equation to solve for d: d + 34 = 51.

Subtract 34 from both sides: d = 17.

Therefore, you have 17 dimes and 34 quarters.

Challenge) Solve for a. Answer as a mixed number. A=______

Answers

The value of the a  in the mixed form is \(-1 \frac{5}{43}\).

What is the equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

To solve for a, we can begin by isolating the variable on one side of the equation.

First, we can subtract 3 from both sides to get:

-7/12 - 3 = 4/a

Next, we can simplify the left side by finding a common denominator of 12:

-7/12 - 3 * 12/12 = 4/a

-7/12 - 36/12 = 4/a

-43/12 = 4/a

To solve for a, we can multiply both sides by a/4:

(-43/12) * (a/4) = 1

Multiplying the left side gives:

-43a/48 = 1

Dividing both sides by -43/48 gives:

a = -48/43

To express this as a mixed number, we can divide the numerator by the denominator:

-48 ÷ 43 = -1 with a remainder of 5

Therefore, the value of the a  in the mixed form is \(-1 \frac{5}{43}\).

Answers

a-1. The profitability index for Project I is 1.180, and for Project II it is 1.414.

a-2. Based on the profitability index decision rule, the firm should accept Project II.

b-1. The NPV for Project I is $9,699.57, and for Project II it is $7,872.48.

b-2. According to the NPV decision rule, the firm should take Project I since it has a higher NPV.

a-1. To calculate the profitability index for both projects, we divide the present value of cash inflows by the initial investment (cash outflow).

For Project I:

PV of cash inflows = $25,000 / (1 + 0.11)^1 + $25,000 / (1 + 0.11)^2 + $25,000 / (1 + 0.11)^3 = $63,699.57

Profitability Index (Project I) = PV of cash inflows / Initial investment = $63,699.57 / $54,000 = 1.180

For Project II:

PV of cash inflows = $10,200 / (1 + 0.11)^1 + $10,200 / (1 + 0.11)^2 + $10,200 / (1 + 0.11)^3 = $26,872.48

Profitability Index (Project II) = PV of cash inflows / Initial investment = $26,872.48 / $19,000 = 1.414

a-2. According to the profitability index decision rule, a project with a profitability index greater than 1 is considered acceptable. Therefore, based on the profitability indexes calculated:

Project I has a profitability index of 1.180

Project II has a profitability index of 1.414

Since Project II has a higher profitability index, the firm should accept Project II.

b-1. To calculate the net present value (NPV) for both projects, we find the present value of cash inflows and deduct the initial investment (cash outflow).

For Project I:

NPV (Project I) = PV of cash inflows - Initial investment = $63,699.57 - $54,000 = $9,699.57

For Project II:

NPV (Project II) = PV of cash inflows - Initial investment = $26,872.48 - $19,000 = $7,872.48

b-2. According to the NPV decision rule, a project with a positive NPV is considered acceptable. Comparing the NPVs calculated:

Project I has an NPV of $9,699.57 (positive)

Project II has an NPV of $7,872.48 (positive)

Based on the NPV decision rule, the firm should take Project I since it has a higher NPV.
