Answer:

70

Step-by-step explanation:

Answer:

The answer is 70.

Step-by-step explanation:

In order to find the value of k(-5), you have to substitute the value of x into the function k :

[tex]k(x) = 6x + 100[/tex]

Let x = -5,

[tex]k ( - 5) = 6( - 5) + 100[/tex]

[tex]k( - 5) = - 30 + 100[/tex]

[tex]k( - 5) = 70[/tex]

Answer:

Around 34.14% of the cookies are between 11.32 and 11.35 grams.

Step-by-step explanation:

In a normal distribution around 68.28% of the values are around minus one to one standard deviation. In this case we want to know the percentage of values that are between zero and one standard deviation, therefore the percentage of values that are in that range is given by 68.28% / 2 , which is equal to 34.14%.

Answer:

Area of regular polygon: ( About ) 442.8 units^2; Option C

Step-by-step explanation:

~ In this situation we can apply the formula 1/2 * a * P, provided a ⇒ apothem, and P ⇒ Perimeter of the shape ~

Here we are directly provided with the apothem, which makes it a whole lot easier than dividing the figure into triangles, drawing an altitude to one of the triangles, determining the tan degree of the triangle etc.

1. Given one of the sides to be 11 units, the perimeter of this hexagon would be 11 * 7, as it is implied that it is a regular polygon ⇒ Perimeter: 77 units

2. Now let us substitute the apothem and perimeter into this formula to determine the area of this regular polygon: 1/2 * 11.5 * 77 ⇒ 442.75

Area of regular polygon: ( About ) 442.8 units^2

Answer:

Step-by-step explanation:

The distance between the parallel lines remains constant.

Answer:

y=-5x+35

Step-by-step explanation:

The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.

First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).

We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.

So, we find that the m value is equal to -5.

The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.

Thus we have the equation of the line is y=-5x+35.

Answer:

Option D.

Step-by-step explanation:

From the given graph,

Center of the circle = (-4, -2)

This circle passes through a point (0, -3),

Radius of the circle = Distance between center and point (0, -3)

r = [tex]\sqrt{(0+4)^{2}+(-3+2)^{2}}[/tex]

r = [tex]\sqrt{17}[/tex]

Standard equation of the circle is,

(x - h)² + (y - k)² = r²

Where (h, k) is the center and r is the radius of the circle.

By putting the values in this equation,

(x + 4)² + (y + 2)² = (√17)²

(x + 4)² + (y + 2)² = 17

Option D. will be the answer.

Answer:

110 words in 5 min, 220 words in 10 min

Step-by-step explanation:

y = mx (there is no intercept because you can't type anything in 0 minutes)

66 = 3m

m = 22

y = 22x

5 minutes:

y = 22(5) = 110 words

10 minutes:

y = 22(10) = 220 words

Answer:

The larger pyramid is 5,376 inches^3 greater

Step-by-step explanation:

To calculate how many inch greater the volume of the larger pyramid compared to the volume of the new smaller pyramid, what we do is to calculate the volume of both.

Mathematically, the volume of a square pyramid = area of base * height of pyramid

For the larger pyramid, length of base is 16 inches and height is 24 inches;

The area of base is L^2 since it is a square; 16 * 16 = 256 inches^2

The volume is thus 256 * 24 = 6,144 inches^3

For the smaller pyramid also, we use the same approach but this time, length of base is 8 inches and height is 12 inches

Area of base = 8 * 8 = 64 inches^2

Volume = 64 * 12 = 768 inches^3

Now how much more is the larger pyramid, that would be the volume of the larger pyramid- volume of the smaller pyramid = 6144 - 768 = 5,376 inches^3

Answer:

y = 1500 - 75t

It will take her 20 months to pay off her TV loan.

Step-by-step explanation:

Vanessa purchased a smart TV for $1500 on a payment plan.  After 4 months of purchasing the TV her balance was $1200 . 7 month her balance was $975.  The amount she pays every month can be calculated as follows. After 4 months she paid 1500 - 1200 = $300. Her balance is $1200. Divide 300 by 4 to get $75 per month as the amount she pays every month.

1500 - 975 = 525/7 = $75 per month.

The equation to model the balance y after t months can be expressed below.

y = 1500 - 75t

where

y = balance

t = number of months

Her balance should be $0 for her to be able to pay off the TV loan.

y = 0

-1500 = -75t

divide both sides by -75

t = -1500/-75

t = 20

It will take her 20 months to pay off her TV loan.

Answer:

68 miles

Step-by-step explanation:

Distance biked on the first five days =67,60 ,69 ,68 , and 70 miles

Let the distance biked on the sixth day=x miles

We want his average for the 6 days =67 miles per day

Therefore:

[tex]Average=\dfrac{67+60+69+68+70+x}{6} \\67=\dfrac{334+x}{6}\\$Cross multiply\\67*6=334+x\\402=334+x\\x=402-334\\x=68 miles[/tex]

He needs to bike 68 miles on the sixth day to get an average of 67 miles per day/

Answer:

380.8cm³

Step-by-step explanation:

Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]

'r' is the radius.

'h' is the height.

We are given a height of 9.9 cm and a diameter of 7cm.

The radius is half the diameter.

Divide 7 by 2:

[tex]7/2=3.5[/tex]

The radius is 3.5 cm.

Solve for The Volume (Using 3.14 for pi):

[tex]V=3.14*3.5^2*9.9\\\rightarrow3.5^2=12.25\\V=3.14 * 12.25 * 9.9\\V=38.465 * 9.9\\\boxed {V=380.8035}[/tex]

380.8035 ≈ 380.8

The volume of the cylinder should be 380.8cm³.

Your answer is A. (0,0)

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept, which is where the line cuts the y-axis.

In the line y = 4x, the ‘m’ would be 4 and the ‘+ b’ would be 0, which means that the line cuts the y-axis when y = 0.

There are only 2 answer options that have y = 0, A (0, 0) and D (4, 0). To find out which is correct, we can substitute in y = 0 into the equation y = 4x to see what the x-value would be:

y = 4x

0 = 4x

0 = x

Therefore the answer is A.

I hope this helps!

Think of y = 4x as y = 4x + 0.

If you don't have anything you're adding to

adding or subtracting to then it's 0.

Now our equation is in slope-intercept form.

We can write this as the ordered pair (0, 0).

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

Answer:

1) The volume of the model is 3159 in.³

2) The height of the real facility is 61.94 ft

Step-by-step explanation:

1) The parameters given are;

Volume of the Estabrook hall = 117 ft³

Scale of model = 1:4

For the scale factor of a volume, we have;

[tex]Volume \, scale \, factor =\left (\frac{a}{b} \right )^3 = \left (\frac{1}{4} \right )^3 = \frac{1}{64}[/tex]

That is the volume of the model is 1/64 times the volume of the actual Estabrook hall restrooms or

[tex]\frac{1}{64} \times 117 \, ft^3= 1\tfrac{53}{64} \, ft^3[/tex]

∴ The volume of the model = 1.83 ft.³

1 ft.³ = 1728 in.³

∴ 1.83 ft.³ = 1.83 ft.³ × 1728 in.³/ft.³ = 3159 in.³

2) Where the model of the floor has an area of 117 in.²

Therefore, since the volume of a rectangular prism shape = Floor area × Height, we have

The height, h = Volume/(floor area) = 3159/117 = 185.8 in.

From a scale of 1:4, we have that the height of the real facility = 4 × 185.8 in.

Hence, the height of the real facility = 743.3 in = 61.94 ft.
