Answer: 3 copies of 5 tenths = 3*0.5 = 1.5

Step-by-step explanation:

Ok, if we have:

"3 copies of a number B"

This is written as:

3*B

And we have that the number B is "5 tenths"

Now, a tenth is the first digit after the decimal point.

Then 5 tenths = 5*0.1 = 0.5

B = 0.5

3 copies of 5 tenths = 3*0.5 = 1.5

I made 12 dog treats using 1 cup of peanut butter. If I want to make 36 dog treats, how much peanut butter will I need? Write a
MaRussiya [10]

Answer:

You will need 3 cups peanut butter to  make 36 dogs treats.

Peanut butter Cup  :  The dog treats made =  1: 12

Step-by-step explanation:

12 dog treats  = 1 cup  

So, by UNITARY METHOD

1 dog treat = (1/12) cup

So, 36 dog treats = 36 x (1/12) cup = 3 cups

So, you will need 3 cups peanut butter to  make 36 dogs treats.

If 1 cup = 12 Dog Treats

then 1 x 3 cup = 12 x 3 dog treats

or, 3 Cups = 36 dog treats

The ratio of the Peanut butter cup  :  The dog treats made =  1: 12

What is the slant height of a regular pyramid if its lateral area is 160 units² and the perimeter of the base is 40 units?
SSSSS [86.1K]

Answer:

The slant height of a regular pyramid is l=8\ units

Step-by-step explanation:

we know that

The lateral area of a regular pyramid is equal to

LA=\frac{1}{2}Pl

where

LA is the lateral area

P is the perimeter of the base

l is the slant height

we have

LA=160\ units^{2}

P=40\ units

substitute in the formula and solve for l

160=\frac{1}{2}(40)l

160=20l

l=160/20

l=8\ units
