Answer: 81/100
Step-by-step explanation:
I don't guarantee you I am right but..
first, solve for the exponents after substituting the numbers in
3/5 x 3/5 is 9/25
since b's exponent is negative, you change the fraction into its reciprocal and then do it with the exponent but positive
2/3^-3 to 3/2^3 and 3/2 x 3/2 is 9/4
then you mutiply both numbers to get 9/4 x 9/25 is 81/100
The Canadian goose flew for 4 hours and the Great blue heron flew for 10 hours
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let a represent the time flown by the goose and b represent the time flown by the heron. Hence:
a + b = 14 (1)
Also:
20a + 10b = 180 (2)
From equation 1 and 2:
a = 4, b = 10

Answer: 17.5%
Step-by-step explanation:
Percentage of chips given to Jackie = 20%
Percentage of chips given to Ronald = 20%
Percentage of chips given to Mark = 1/4 × 100 = 25%
From the above calculation, we can see that Ms Johnson has given out ((20% + 20% + 25%) = 65% worth of chips out. The percentage she'll have left will be:
= 100 - 65
= 35%
Since Susan takes half of what's left, the percent that Ms. Johnson has left to eat will be:
= 1/2 × 35%
= 17.5%
She has 17.5% left to eat.
Cosine = adjacent / hypotenuse
cosine = 1 / square root (2)
Answer:
V = (5 feet) (2 feet) (2 feet) V = 20 cubic feet To convert the volume into gallons, multiply the above answer by 7.48 since there are 7.48 gallons of water in one cubic foot. This will give us an answer of 150 gallons of water.
