Andy is scuba diving.He starts at sea level and then descends 10 feet in 2 1/2 minutes. a. how would you represent Andy's descend as a unit rate? Express your answer as an integer.
b. How much feet can he descend in 6 minutes?

Answers

Answer 1
Answer: Descent  = 10 feet
Time required = 2 1/2 minutes.
The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min

In 6 minutes, the descent will be
(4 ft/min)*(6 min) = 24 ft

Answer:
(a) 4 feet/minute
(b) 24 feet

Answers

6x6  is 6² in expanded form.

Given that, the expression 6² to expand the equation,

The expanded form of the given expression will be 6 multiplied by 6.

In another word, the expanded form of the given expression will be:

6²  = 6*6

Therefore, option D is correct.

Anything to the power of 2 is that number times itself. So 5^2 would be 5*5, that means 6^2 is 6*6

Jerome bought screen for 59 cents per sq ft. how much did 12 sq ft cost

Answers

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.

Leo is purchasing a bike that is on sale for 30% off. He knows the function that represents the sale price of his bike is c(p) = 0.7p, where p is the original price of the bike. He also knows he has to pay 12% sale's tax on the bike. The price of the bike with tax is f(c) = 1.12c, where c is the sale price of the bike.Determine the function that can be used to calculate the final price of Leo's bike by solving for f[c(p)].
f[c(p)] = 1.82cp
f[c(p)] = 1.82p
f[c(p)] = 0.784cp
f[c(p)] = 0.784p

Answers

f[c(p)] = (1.12)(0.7p) = 0.784p

A single function should have a single variable.

Answer: The answer would be f[c(p)] = (1.12)(0.7p) = 0.784p

Step-by-step explanation:

A single function should have a single variable.
