Step-by-step explanation:

3x² + 3x - 1

should turn into x + 5.

so, let's subtract (x + 5), and the result is then what we have to add in negative version to the original expression (like with subtractions and additions if regular numbers).

3x² + 3x - 1 - x - 5 = 3x² + 2x - 6

so, we need to add -(3x² + 2x - 6) = -3x² - 2x + 6

Answer:

To find the missing angle you have to use cosine so it would be cos^-1(26.2/27) since cosine is adjacent over hypotenuse so the missing angle x is 13.98 but rounded to the nearest tenth its approximately 14.

The equation could be used to solve for charles' rate if it is represented by x is 2x=54.

In the given question wehave to find the equation could be used to solve for charles' rate if it is represented by x.

Bill riding a bicycle at an average rate of 9 mph.

Charles' rate is x.

So the relative rate = x−9 mph

Distance traveled by Bill in 4 hours = 9*4 =36 mph

Charles' overtook Bill in 2 hours. So

Relative Rate = Distance/Time

x−9=36/2

Multiply by 2 on both side. We get

2(x−9)=36

Simplifying

2x−18=36

Add 18 on both side, we get

2x=36+18

2x=54

Hence, the equation could be used to solve for charles' rate if it is represented by x is 2x=54.

Answer:

Sorry I can't understand.

Answer:

1. 49

2. 35

3. 4

4.  140

5. 189

Step-by-step explanation:

1. Face A is a square with a height of 7 cm, so the length and width have to be 7 too. 7*7=49.

2. area=base*height/2. The base is 7, the height is 10, their product is 70. 70/2=35.

3. In the net, 4 traingles labeled B are present

4. area of b triangles*number of b triangles: 35*4=140

5. square+b triangles=surface area. 49+140=189.

Answer:

below

Step-by-step explanation:

1. Area for Face A (the square)

Formula: A=a^2

A = Area, a = side

Fill in:

A = 7^2

Solve:

7 ^2, aka 7 x 7 = 49

2. Area for Face B (the flat triangles)

Formula: A = 1/2 × b × h

b = base, h = height

Fill in:

A = 1/2 × 7 × 10

Solve:

(Multiplying by 1/2 is the same as dividing by 2)

A = 1/2 x 7 x 10
7 × 10 = 70

divide by 2

70/2 = 35

Now we count how many Face B triangles there are, and add the area of each one together:

# of Face B Triangles: 4

multiply it by 35, or just add 35 4 times: 140

3. Total Surface Area for Pyramid:

Base Surface Area = 7^2 = 49

Lateral Surface Area = 2 × 7 × √(7/2)^2 + 10^2 =148.32734070292

Total Surface Area = 197.32734070292

Step-by-step explanation:

Area of Rectangle Prism = Area of base x height

Answer:

The maximum height the ball will reach is 29,141 feet.

The time when it reached its maximum height is 1.094 seconds.

2,443 seconds after throwing the ball, it will touch the ground.

Step-by-step explanation:

The function h (t) = - 16t² + 35t + 10 is a quadratic function of the form f (x) = ax² + bx + c, where a = -16, b = 35 and c = 10. To calculate the maximum height, you must then find the maximum of the function. In other words, Quadratic functions have a maximum (if a <0) or a minimum (if a> 0). This point is the vertex of the parabola.

The vertex coordinate on the x axis can be calculated by:

\(x=\frac{-b}{2*a}\)

The value of the vertex on the y axis is obtained by substituting the value of "x vertex" in the function f (x), that is, by calculating f (\(\frac{-b}{2*a}\)).

In this case, where h (\(\frac{-b}{2*a}\)) is the maximum height:

\(t=\frac{-b}{2*a}=\frac{-35}{2*(-16)} =1.09375\)≅ 1.094 seconds

So: h(1.094)= -16*1.094² + 35*1.094 + 10

h(1.094)=29.151

The maximum height the ball will reach is 29,141 feet.

The time when it reached its maximum height is 1.094 seconds.

To calculate the number of seconds after the ball is thrown it will hit the ground, you must calculate the roots of the quadratic function. For this you must apply:

\(x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}\)  

where x1, x2 are the two roots of the function f(x)=a*x² +b*x + c

In this case:

\(t1,t2=\frac{-35+-\sqrt{35^{2}-4*(-16)*10 } }{2*(-16)}\)

Solving, you get t1=-0.256 and t2=2.443

Since the time cannot be negative, 2,443 seconds after throwing the ball, it will touch the ground.

Step-by-step explanation:

The question is incomplete, as the box plot is not attached.

However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores

To answer this question, I will make use of the attached box plot.

IQR is calculated as:

\(IQR = Q_3 - Q_1\)

\(Q_1\) and \(Q_3\) are represented by the vertical edges of the rectangle in the box plot. [See attachment]

Reading \(Q_1\) and \(Q_3\), we have:

\(Q_1 = 37\)

\(Q_3 = 50\)

The IQR is:

\(IQR = 50 - 37\)

\(IQR = 13\)

Hence, the range that describes the middle 50% of the attached plot is 13

Work Shown:

Add up the values in the table:

170+135+150+145 = 600

There are 600 orders in total. Of those 600, we have 135+145 = 280 that are for lemonade or for orange juice. This means roughly 280/600 = 0.4667 of all the drinks are either lemonade or orange juice.

Assuming this ratio keeps up, we can multiply 0.4667 with 30 to get

30*0.4667 = 14.001 which rounds to 14

This represents the estimated number of drinks in the next 30 orders that are either lemonade or orange juice.

Marc's current marginal tax rate can be determined by referring to the U.S. tax rate schedule for the year 2021 based on his taxable income.

To calculate Marc's current marginal tax rate, we need to look at the U.S. tax rate schedule for the year 2021. The tax rate schedule consists of several tax brackets, each with its corresponding tax rate. As taxable income increases, individuals move into higher tax brackets and are subject to higher tax rates. Based on Marc's taxable income of $260,000, we would need to refer to the tax rate schedule to determine his marginal tax rate. As the exact tax rates within the brackets can vary, it's important to consult the specific tax rate schedule for the given year.

By locating the corresponding tax bracket for $260,000 in taxable income, we can identify the applicable tax rate. Marc's current marginal tax rate would be the tax rate associated with the bracket that includes his interest.

Quartiles are three numbers that divide sorted data into four equal portions with an equal amount of observations each. A quantile is a sort of quantile. The first quartile is sometimes known as the lower quartile or Q1. Second quartile: Also known as the median or Q2. Third quartile: Also known as the higher quartile or Q3.

Here,

To find the upper fence, we need to calculate the following statistics:

Q1 (first quartile), Q2 (median), and Q3 (third quartile) of the data

Interquartile range (IQR), which is the difference between Q3 and Q1

Upper fence, which is Q3 + 1.5 * IQR

First, we need to order the data in ascending order:

339, 350, 358, 388, 430, 458, 458, 463, 480, 489, 501, 536

Next, we can find the quartiles:

Q1 = 388

Q2 = 458

Q3 = 501

IQR = Q3 - Q1 = 501 - 388 = 113

Finally, we can calculate the upper fence:

Upper fence = Q3 + 1.5 * IQR = 501 + 1.5 * 113 = 674

This means that the cutoff point for the number of minutes at which the customer should be contacted is 674 minutes, rounded to the nearest minute.

Answer:

y = -5x - 5

Step-by-step explanation:

to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values  (-2 - 0)

so slope = 10/-2 or -5/1

to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5

The values based on the proportion will be:

240 / 60 = 1600 / 400

180 / 240 = 300 / 400

60 / 240 = 100 / 400

60 / 400 = 36 / 240

Ratio in Mathematics simply demonstrates how many times one number can be able to fit into another number. It should be noted that ratios contrast two numbers by dividing them. In this case, A/B will be the formula if one is comparing one variable (A) to another variable (B).

Answer:

angle ACD=  138 degrees

Step-by-step explanation:

As angle W Z X is  opposite to the angle CZD. Angle CZD is also 82 degree.

If we consider the triangle CZD the angle D  is equal to 180 - 56 =  124 degrees.( angles on a straight line= 180)

The sum of the angles of a triangle is equal to 180 degrees

<C+<D +<Z= 180

<C= 180- 82-56

<C= 42 degrees

Since Angle DCZ= 42 degrees

angle ACD= 180-42  ( angles on a straight line)

angle ACD=  138 degrees

It is important to note that this statement is about the process of constructing intervals, not about any particular interval we might construct.

To construct a 95% two-sided confidence interval on the death rate from lung cancer, we need to know the sample proportion, sample size, and the level of confidence. Given the problem statement, we have:

Sample proportion (P) = 360/900 = 0.4

Sample size (n) = 900

Level of confidence = 95%

We can use the formula for the confidence interval for a population proportion as follows:

Confidence interval = P ± zα/2 * √(P(1-P)/n)

where P is the sample proportion, n is the sample size, zα/2 is the z-value from the standard normal distribution with a level of significance of α/2 (α/2 = 0.025 for a 95% confidence interval).

To find the z-value, we can use a z-table or a calculator. Using a calculator, we find the z-value for α/2 = 0.025 to be 1.96.

Substituting the values into the formula, we get:

Confidence interval = P ± zα/2 * √(P(1-P)/n)

Confidence interval = 0.4 ± 1.96 * √(0.4(1-0.4)/900)

Confidence interval = 0.4 ± 0.034

Therefore, the 95% two-sided confidence interval on the death rate from lung cancer is (0.366, 0.434).

This means that we are 95% confident that the true death rate from lung cancer falls within this interval. It is important to note that this statement is about the process of constructing intervals, not about any particular interval we might construct.

the only one that would make sense is D because it says 1 pair of parallel and the left one only has one pair

Step-by-step explanation:

(you might want to ask your teacher though because its kind of misleading)

The missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

We know that the sum of angles on a straight line is 180 degrees. Thus, we can say that;

∠1 + 118° = 180°

∠1  = 180 - 118

∠1 = 62°

We also know that sum of angles in a triangle is equal to 180°. Thus;

∠1 + ∠2  + 73 = 180

Plugging in the relevant value gives;

62 + ∠2  + 73 = 180

∠2 = 180 - 135

∠2 = 45°

∠2 + ∠3 = 180 - (∠1 + 49)

∠2 + ∠3 = 180 - (62 + 49)

45° + ∠3 = 69

∠3 = 22°

Thus, we conclude that the missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.
