1. The value of 34% of 850 is 289.

3. The amount that Kepley paid for the tool is $120.

From the information, we want to calculate 34% of 850. This will be calculated thus:

= 34% ×850

= 34/100 × 850

= 0.34 × 850

= 289

The amount paid for the tool will be:

= Price or tool - Discount

= $200 - (40% × $200)

= $200 - $80

= $120

Answer:

They ate 1/6 of the donuts

Step-by-step explanation:

They bought 18 donuts. 1/2 of 18 is 9. 1/3 of 9 is 3. To find the fraction, divide 3 by 18. Simplify the fraction. You are left with 1/6.

Answer:

31 + 32 + 33 = 96.

Answer:

107º

Step-by-step explanation:

Okay, if 135 is adjacent to an ungiven side, then to find that, you subtract 135 from 180.

180 - 135 = 45

So the other side is 45. Now we find the last unknown given side, and since we know 180 degrees is the sum of the degrees in a triangle, we do:

28 + 45 + x = 180

73 + x = 180

Subtract 73 on both sides you get,

x = 107.

Measure DEF is 107.

This is a case of easement appurtenant

What is easement?

An easement is a nonpossessory right to use and/or enter another's real property without owning it. It is "best shown by a right of way that one landowner, A, may have over the land of another, B." In most countries, an easement is a property right and sort of incorporeal property in and of itself. Real covenants and equitable servitudes are analogous to easements. The Restatement (Third) of Property in the United States attempts to integrate these notions as servitudes. Easements are useful for allowing persons to access other properties or resources by granting access across two [further explanation needed] or more pieces of property.

Answer:

y= 13/4x - 21

Step-by-step explanation:

What we need to do is find the slope first. We know the slope formula is

y_1 minus y_2/ x_1 minus x_2. I am assuming that one point is (8,5) the other is (4,-8). So when we insert these coordinates into the equation,

[5-(-8)/8-4] we result with 13/4 as the slope. We can now use the slope-intercept form! ( y=mx+b) 13/4 can be put into this equation as m, because its the slope. So, now we have y=13/4x+b. The last step to find the equation is inserting the first coordinates given.(8,5)     5= 8(13/4)+b. 8 times 13 divided by 4 is 26. This is what we factored to so far: 5= 26+b. We are trying to solve for b! So lastly, 5-26= -21 and that is b. Once again, we can use the slope intercept formula since we know both b and the slope. FINAL ANSWER: y=13/4x-21. I hope this can help!

Answer:

Step-by-step explanation:

Since ABCD is a parallelogram, we know that its opposite sides are parallel. That is, AB is parallel to CD and BC is parallel to DA.

To prove that AB = CD, we can use the fact that opposite sides of a parallelogram are congruent. That is, AB is congruent to DC. So, we can write:

AB = DC

Similarly, to prove that BC = DA, we can use the same fact. That is, BC is congruent to AD. So, we can write:

BC = AD

Therefore, we have proven that AB = CD and BC = DA, which shows that the opposite sides of the parallelogram ABCD are congruent.

Answer:

(10, 5π/3)

Step-by-step explanation:

To convert rectangular coordinates (5, -5√3) to polar form, we can use the following formulas:

r = √(x^2 + y^2)

θ = arctan(y/x)

Substituting the given values, we get:

r = √(5^2 + (-5√3)^2) = √(25 + 75) = √100 = 10

θ = arctan((-5√3)/5) = arctan(-√3) = -π/3

Note that the value of θ is in the fourth quadrant, which corresponds to a negative angle. However, we need to express the angle θ in the range 0 ≤ θ < 2π. To do this, we can add 2π to the angle if it is negative:

θ = -π/3 + 2π = (5π/3)

Therefore, the rectangular coordinates (5, -5√3) in polar form are (10, 5π/3).

Answer:

\(\%Absent = 80.20\%\)

Step-by-step explanation:

Given

The attached data

Required

%Absentee on Friday

First, calculate the total present

\(Present = 42 + 36 + 40 + 36 + 38\)

\(Present = 192\)

Calculate the %Present on Friday

\(\%Present = \frac{Friday}{Present} * 100\%\)

\(\%Present = \frac{38}{192} * 100\%\)

\(\%Present = \frac{3800}{192}\%\)

\(\%Present = 19.80\%\)

Using complement rule:

\(\%Absent = 100\% - \%Present\)

\(\%Absent = 100\% - 19.80\%\)

\(\%Absent = 80.20\%\)

Answer:

Option 2

Step-by-step explanation:

The value of x in the triangle is determined as 45.

The value of x in the triangle is calculated by applying the following formula,.

The measure of angle ABD = 0.2x + 52

The measure of angle CBD = 0.2x + 42

From the diagram, we can set-up the following equations;

x + 16 = 0.2x + 52

Simplify the equation above, by collecting similar terms;

x - 0.2x = 52 - 16

0.8x = 36

Divide both sides of the equation by " 0.8 "

0.8x / 0.8 = 36/0.8

x = 45

Thus, the value of x in the triangle is calculated by equating the appropriate values to each other.

Answer:

$0.0756 for 18 oz

$0.0634 for 32 oz

Step-by-step explanation:

a) The 95% confidence interval for the mean length of the skulls of this species of bird is (5.35, 6.01) cm.

b) The 95% confidence interval for the true standard deviation of the skull length of the given species of bird is (0.18, 0.40) cm.

(a) To find a 95% confidence interval for the mean length of the skulls of this species of bird, we can use the following formula:

mean ± (t-score * standard deviation / square root of sample size)

Where mean is the sample mean (5.68 cm), standard deviation is the sample standard deviation (0.29 cm), and sample size is the number of skeletons (10).

To find the t-score, we can use the t-distribution table for 9 degrees of freedom (sample size - 1). For a 95% confidence interval, the t-score with 9 degrees of freedom is 1.833.

Plugging in the values, we get:

5.68 ± (1.833 * 0.29 / √(10))

= 5.68 ± 0.33

So the 95% confidence interval for the mean length of the skulls of this species of bird is (5.35, 6.01) cm.

(b) To find a 95% confidence interval for the true standard deviation of the skull length of the given species of bird, we can use the following formula:

standard deviation / √(sample size) * t-score

Where standard deviation is the sample standard deviation (0.29 cm), and sample size is the number of skeletons (10).

To find the t-score, we can use the t-distribution table for 9 degrees of freedom (sample size - 1). For a 95% confidence interval, the t-score with 9 degrees of freedom is 2.306.

Plugging in the values, we get:

0.29 / √(10) * 2.306

= 0.11

So the 95% confidence interval for the true standard deviation of the skull length of the given species of bird is (0.29 - 0.11, 0.29 + 0.11) = (0.18, 0.40) cm.

Answer:

11860.22 rev/hour

Step-by-step explanation:

The diameter if a cylinder, d = 21.02 inches

Radius, r = 10.51  inches

or

r = 0.875 feet

The linear speed of a point on the cylinder's surface is 18.12 ft/sec.

We need to find the angular speed of the cylinder.

The relation between the linear speed and the angular speed is given by :

\(v=r\omega\)

Where

\(\omega\) is angular speed

\(\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s\)

or

\(\omega=11860.22\ rev/hour\)

So, the required angular speed of the cylinder is 11860.22 rev/hour.

Step-by-step explanation:

The body reverses direction whenever we go from Positve velocity to negative velocity or vice versa.

So here it is (2,7) exclusive then (7,10) exclusive.

A constant speed means a slope of 0. Here it is (3,6).

c. Since speed is non negative, we would reflect any part of the velocity function that is below the time.axis about the time axis

So we would get

Above is the function, don't worry bout the math part.

D. Knowing that acceleration is the derivative of velocity with respect to time, the derivative of any linear function is the slope of that linear function. So if we find the slope of different paths, we will get a constant and then we can graph it

We must use the original graph because acceleration is a vector meaning it can be negative.

m = (y2-y1) / (x2-x1) for (x1 = -3, y1 = 2) and (x2 = 7, y2 = 9)

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.
