Answer:

12

Step-by-step explanation:

The Pythagorean theorem shows that 400 or 20² - 256 or 16² = 144 or 12² which means that the other side is 12

Enter an equation in point-slope form for the line.
MissTica

Answer:

y+1=4(x+2)

Step-by-step explanation:

Hi there!

Point-slope form: y-y_1=m(x-x_1) where m is the slope and (x₁,y₁) is the given point

y-y_1=m(x-x_1)

Plug in the slope and the point

y-(-1)=4(x-(-2))\\y+1=4(x+2)

I hope this helps!

Alright Soldier I need help, Solve for Percent Error, Calculate the percent error if the experimental value of the density of go
Dima020 [189]

Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

The revenue from selling xshirts is r(x) = 12x.
algol [13]

Answer:

D. p(x)=7x-20

Step-by-step explanation:

r(x) = 12x\\c(x) = 5x + 20\\p(x) = r(x)-c(x)\\p(x)=12x-(5x+20)\\p(x)=12x-5x-20\\p(x)=7x-20

Simply subtract the two functions from each other and simplify to get the result.

Who's most brainiest to answer these 2 questions? Will mark ya'll brainiest. Pls show all work!
stepladder [879]

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.
