Answer:
The surface area would be 28 square feet.
Step-by-step explanation:
To solve this, input the values for each of the variables every time you see it. l = length, w = width and h = height.
SA = 2lw + 2hw + 2hl
SA = 2(2)(1) + 2(4)(1) + 2(4)(2)
SA = 4 + 8 + 16
SA = 28
Answer:
See explanation
Step-by-step explanation:
Each ounce of fruit will supply
- 1 unit of protein,
- 2 units of carbohydrates,
- 1 unit of fat.
Each ounce of nuts will supply
- 1 unit of protein,
- 1 unit of carbohydrates,
- 1 unit of fat.
Let x equal the ounces of fruit and y equal the ounces of nuts to be used in each package.
Then x ounces of fruit will supply
- x units of protein,
- 2x units of carbohydrates,
- x units of fat
and y ounces of nuts will supply
- y units of protein,
- y units of carbohydrates,
- y units of fat.
Every package must provide
- at least 7 units of protein, then x+y≥7,
- at least 11 units of carbohydrates, then 2x+y≥11,
- and no more than 10 units of fat, then x+y≤10.
A. You get the system of three inequalities

B. See attached diagram

Forumla for circumference is
pi x diameter
or
pi x 2 x radius
so we are going to use the second formula to estimate the answer without a calculator.
3 x 2 x 125
3 x 2 =6
6 x 125 = 750.
the closest answer is 785m. That is the answer.
