Answer:

Step-by-step explanation:

Surface area is the total surface.  So first, find each surface...two triangles, same size and three rectangles, same size.  

So you will have to add each....triangle+triangle+rectangle+rectangle+rectangle.

Area of a triangle = 1/2(b)(h)               with b=base and h=height

Plug in knowns         1/2(15)(13)=A

Multiply 15X13=195  Then divide by 2.  195/2=97.5  

The area of each triangle is 97.5 yd.

Area of a rectangle = (L)(W)                  with L=Length and W=Width

Plug in knowns          (15)(24)=A             Now, multiply

15X24=360

The area of each rectangle is 360 yd.  

We need to add two triangles for front and back. and three rectangls.

97.5+97.5+360+360+360=1275

Surface area is 1,275 yd.

a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving, how many servings can
Anestetic [448]

Answer:

128 servings can be made using 1 gallon of milk.

Step-by-step explanation:

Given that:

1\frac{1}{4} cups of milk make 10 servings

1\frac{1}{4} can also be written as 1.25

Ratio of cups of milk to servings = 1.25 : 10

1 gallon = 16 cups

Let,

x be the number of servings made from 1 gallon

Ratio of cups of milk to servings = 16 : x

This is a direct proportion

1.25 : 10 :: 16 : x

Product of mean = Product of extreme

10*16 = 1.25x

160 = 1.25x

1.25x=160

Dividing both sides by 1.25

\frac{1.25x}{1.25}=\frac{160}{1.25}\\x=128

Hence,

128 servings can be made using 1 gallon of milk.

Given the figure below, find the values of x and z.
stepan [7]

Answer:

z = 96; x = 8.

Step-by-step explanation:

z = 96. This is because the angle measuring z degrees is a vertical angle of the angle measuring 96 degrees, which means that the two angles are congruent.

The angle measuring 5x + 44 degrees forms a straight angle with the 96 degree angle. That means that the measurements of the two angles will add to be 180 degrees.

5x + 44 + 96 = 180

5x + 140 = 180

5x = 40

x = 8

Hope this helps!
