Answer:
A=B
Step-by-step explanation:
Equation 1: 70% of A = 0.7a
Equation 2: 35% of B = 0.35a
Equation 3 = (Equation 2) • 2
Equation 3: 70% of B = 0.7a
Equation 3 = Equation 1
A = B
The expression that represents the total volume of both cubes is

.
The volume of a cube is found by multiplying its length, width, and height; for the first cube, this is
V=(2f)(2f)(2f)=8f³.
For the second cube, this is
V=(3g²)(3g²)(3g²)=27g⁶.
The total area is their sum, so 8f³+27g⁶.
Answer:
5 / 8
Step-by-step explanation:
Given :
Average age of male = 25
Average age of female = 40
Average age of entire membership = 30
The ratio of female to male students :
Male students : Female students
25 : 40
5 : 8
5/8
Answer:
The probability is approximately 0.0699. That's
to be exact.
Step-by-step explanation:
How many ways to choose four out of a total of
boys and girls?
.
How many ways to choose four boys out of a total eight boys?
.
What's the probability that all four persons chosen out of the pack of fourteen are boys? All 1001 ways of choosing four out of fourteen are equally likely. However, only 70 satisfy the conditions. In other words, the probability of choosing four boys out of this group of eight boys and six girls is equal to:

Bella can cut 24 pieces of ribbon from this long strip
<u>Solution:</u>
Given that Bella has 85 feet of ribbons in total
She needs identical strips of ribbon measuring 3.5 feet each
To find: Number of peices of ribbon can she cut from long strip
Number of peices of ribbon can she cut from long strip can be calculated by dividing the total feet of ribbon she has by length of identical strips she needs
<em><u>Mathematically written as:</u></em>


Hence , the number of strip can be 24 each of size 3.5 feet
