Answer:

see explanation

Step-by-step explanation:

The wheel has a measure of 360° , thus

360° ÷ 20 ( number of cars on the wheel )

= 18° ← central angle

-------------------------------------

arc length is calculated as

arc = circumference of wheel × fraction of wheel

= 2πr × $\frac{18}{360}$

= 2π × 25 × $\frac{1}{20}$ = $\frac{50\pi }{20}$ ≈ 7.85 ft

------------------------------------------

area of sector is calculated as

area = area of wheel × fraction of wheel

= π × 25² × $\frac{1}{20}$ = $\frac{625\pi }{20}$ ≈ 98.17 ft²

Pls help I dont get it

Answer:

y=4x

Step-by-step explanation:

The equation of a line is y=mx+b, where m is the slope and b is the y intercept.

The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is $\frac{8-4}{2-1}$ which equals 4.

The y intercept is 0.

Therefore, the equation is y=4x.

Can someone help on these two thanks

forsale [732]

Answer:

C & D

Step-by-step explanation:

For the first one, all you have to do is count how many numbers are behind the decimal point and add them together (1 + 3 = 4) and then you count up the decimal 4 places which would be 0.7416.

For the second one, you divide the days by miles (18/3=6) then you divide the 6 by 72 which would be 12.

Hope this helps!

A particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint. To make the correct shade,

frutty [35]

We get that Shannon did not mix the correct shade as the ratios are not equal.

We are given that a particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint.

This means that the ratio of the paints in that shade is

Red : Blue = 5 : 7.

Now, we are also given that to make the correct shade, Shannon makes 12 quarts of blue paint with 8 quarts of red paint.

Here the ratio becomes:

Red : Blue = 8 : 12

= 4 : 6

= 2 : 3

Now, since both the ratios are not equal, he did not mix the correct shade.

Therefore, we get that Shannon did not mix the correct shade as the ratios are not equal.
