Trinh is serving 112 people cake , 5/8ths are getting chocolate how many people will get carrot ?
Novay_Z [31]
Hey! 

If 112 people are getting cake and 5/8 are getting chocolate, that means the remaining will get chocolate.

8/8 - 5/8 = 3/8

3/8 are getting chocolate. You have to find 3/8 of 112.

3/8 × 112 = 336/8 = 42

42 people are getting carrot cake

What is the equation, in slope-intercept form, of the line that passes through (0, 3) and has a slope of −6?
crimeas [40]

Answer:

The answer is

<h2>y =  - 6x - 3</h2>

Step-by-step explanation:

To find the equation of the line given a point and slope we use the formula

<h3>y  - y_{1} = m(x - x _{1})</h3>

where

m is the slope

( x1 , y1) is the point

From the question the point is (0 , 3) and slope is - 6

Substitute the values into the above formula and solve

That's

<h3>y -  3 =  - 6(x - 0) \\ y - 3 =  - 6x</h3>

We have the final answer as

<h3>y =  - 6x - 3</h3>

Hope this helps you

The scale model of the car is 1:18 the length of the model is 9 1/2 inches how many feet long is the actual
Y_Kistochka [10]

Answer:

14.25 ft

Step-by-step explanation:

1 inch of the model represents 18 inches of the real car. The car's dimensions are 18 times larger than the model's dimensions. Multiply the model dimension by 18 to find the corresponding real dimension.

9 1/2 * 18 = 9.5 * 18 = 171

The actual car is 171 inches long.

Now we need to convert 171 inches to ft.

1 ft = 12 in.

Since we want to eliminate inches and end up with feet, we divide both sides by 12 in.

(1 ft)/(12 in.) = 1

The conversion factor is (1 ft)/(12 in.) to go from inches to feet.

171 in. * (1 ft)/(12 in.) = 14.25 ft

Answer: 14.25 ft
