Mathematics

Oksanka [162]3 years ago

Answer:

y = - 4x + 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 , then

y = - 4x + c ← is the partial equation

To find c substitute (4, - 4) into the partial equation

- 4 = - 16 + c ⇒ c = - 4 + 16 = 12

y = - 4x + 12 ← equation of line

How many inches is each slice of pizza?
mariarad [96]

Hey!


First, let's find the area. The formula for finding area of a circle is: π · r²


Radius is ½ of the diameter. Divide the diameter by 2 to get the radius.


d = 18

18 ÷ 2 = 9


r = 9

r² = 9 × 9 = 81


The area of the whole pizza is 81π. There are 10 slices. Divide the area of the whole pizza by 10 to find the area of 1 slice.


81π ÷ 10 = 8.1π


<em>That means each slice is 8.1π inches²</em>

A package is 15.5 inches long, 8.25 inches wide, and 5.5 inches high. What is the volume of the box? Enter your answer, rounded
Dmitriy789 [7]

Answer: 703.3125 in cubed

Step-by-step explanation:

The formula to find the volume of something is to…

1. Find the area of the base! Remember, area is length x width. In this case we would have 15.5 x 8.25 = 127.875

2. Multiply the base area we just found by the height! In this case, we take 127.875 x 5.5 and this gives us 703.3125 as our final answer!

Unknown variables in Equations <br><br> 1. 7=w/14<br> 2.42/n=7<br> 3. 324/18=a
belka [17]

Answer:

w = 98

n = 6

a = 18

Step-by-step explanation:

Question 1)

7 = w/ 14

All you need to do is multiply each side by 14 to find w:

7(14) = W

W = 98

Question 2)

42/n = 7

For this one, first multiply each side by "n":

42 = 7n

and then divide both sides by 7:

N = 6

Question 3)

All you need to do for this question is divide 324 by 18 to find "a":

324/18 = a

a = 18

I hope this helps!
