Jenna has $43 and Heidi has $17.
Step-by-step explanation:
Total amount = $60
Let,
Amount of Jenna = x
Amount of Heidi = y
According to given statement;
x+y=60 Eqn 1
x=2y+9 Eqn 2
Putting value of Eqn 2 in Eqn 1;
Dividing both sides by 3,
Putting y=17 in Eqn 2
Jenna has $43 and Heidi has $17.

Answer:
37.2m^3
Step-by-step explanation:
Given: The dimension of a cuboid
To Determine: The volume of the container
The volume of a cuboid is calculated by the formula below:
Substitute into the formula the given dimensions
Hence, the volume of the container is 37.2m^3
<span>f(x) = 1/4 to the power of x + 2= 627
f(x) = 1/4 to the power of x + 2= same thing as the one above
f(x) = 1/4 to the power of x - 2= 623
f(x) = 1/4 to the power of x − 2= same thing as the one above

Well, you're asking for a refresher on multiplying fractions, but then the
example at the end of your question uses the symbol for division, not
multiplication. So I'll just give you the rules for both operations, and let you
choose the one you need.
To multiply fractions:
-- Multiply the two numerators.
Write the product on top of a new fraction.
-- Multiply the two denominators.
Write the product on the bottom of the new fraction.
-- The new fraction is the product of the two original fractions.
To divide fractions:
-- Invert (flip) the second fraction.
-- Then multiply them.
-- Their product is actually the quotient of the two original fractions.
Answer:
$127.5
Step-by-step explanation:
15% of $850 is 850 times .15 (% is decimal multiplied by 100)
850 * .15 = $127.50
