Answer:
Step-by-step explanation:
a^2+b^2=400
a^2=400-b^2
a=sqrt(400-b^2) & -sqrt(400-b^2)
-----------------------------------------------
b^2=400-a^2
b=sqrt(400-a^2) & -sqrt(400-a^2)
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
Answer: correct choice is C
33square2 i think that is what it is
Just subtract the smaller volume from the larger:
10 × 10 ×15 - 7 × 9 × 12
First you would multiply 10 × 10 × 15 = 1500 and then multiply 7 × 9 × 12 = 756.
After you would subtract 1500 - 756 which would give you 744
I hope that helped!
Answer:
224 inches cubed.
Step-by-step explanation:
Because the area of a square is 16 square inches, the side length is 4 inches. This is because a square's formula for area is the side squared.
Since the box is 14 inches tall, we multiply 4 inches by 4 inches by 14 inches. This means the answer is 224 inches cubed.
We also notice we don't need a measurement for the base sides, we only need to multiply the area by the height.
