Answer:
4/10 + 3/100 in each of his groups = .43
.43 * 3 = 1.29
his model is short
he should have 1.38
1.38/3 = .46
Step-by-step explanation:
4/10 + 3/100 in each of his groups = .43
.43 * 3 = 1.29
his model is short
he should have 1.38
1.38/3 = .46
divide the discount by the percentage off
so:
99.90/0.27 = 370
the original price was 370 dollars
Answer:
=10a+13b
Step-by-step explanation:
Let's simplify step-by-step.
3(2a+3b)+2(2a+2b)
Distribute:
=(3)(2a)+(3)(3b)+(2)(2a)+(2)(2b)
=6a+9b+4a+4b
Combine Like Terms:
=6a+9b+4a+4b
=(6a+4a)+(9b+4b)
=10a+13b
Answer:
22.5 cm^2
Step-by-step explanation:
Amount of paper is going to be measured in area, so we want the surface area of the cone. Since it is a cub it doesn't have a base, so we don't need to count it.
Area of the cone without the base, or what is called the lateral area is pi*r*s where r is the radius and s is the slant height. and of course radius is d/2 where d is the diameter. so let's plug it in. We know diameter is 6 and slant height is 7.5
SA = pi * r * s
SA = pi * d/2 * s
SA = pi * 6/2 * 7.5
SA = 22.5 cm^2
So you will need 22.5 square centimeters of paper.
