Hey!

------------------------------------------------

~Turn into decimal

6.1% = 0.061

~Multiply

60 x 0.061 = 3.66

------------------------------------------------

Hence, 3.66 is 6.1% of 60!

------------------------------------------------

Hope This Helped! Good Luck!

just olya [345]

Answer:

Cost to travel 75 miles = 11.55 $

Explanation:

A scooter can travel between 22 and 28 miles on each gallon of gasoline.

Average distance a scooter can travel with each gallon of gasoline = (22+28)/2 = 25 miles.

One gallon of gasoline costs between $3.75 and 3.95 per gallon.

Average cost for one gallon of gasoline = (3.75+3.95)/2 = 3.85 $

We need to find cost for traveling 75 miles.

Gasoline required = Total miles/ Average distance a scooter can travel with each gallon of gasoline

= 75/25 = 3 gallons.

Cost to travel 75 miles = Gasoline required x Average cost for one gallon of gasoline

= 3 x 3.85

= 11.55 $

Once his parachute is open, a skydiver descends at a rate of 25 feet per second. 90 seconds after the parachute opens, his altit

ss7ja [257]

Using the information given and linear function concepts, it is found that:

a) The equation is: $y(t) = -25t + 5000$ .

b) The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.

c) It takes 200 seconds for the skydiver to reach the ground.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y(t) = mt + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when t changes by 1.

b is the y-intercept, which is the value of y when x = 0.

Item a:

The skydiver descends at a rate of 25 feet per second, hence $m = -25$ .

Then:

$y(t) = -25t + b$

<u>90 seconds after the parachute opens, his altitude is 2750 feet</u>, which means that when $t = 90, y = 2750$ , which is used to find b. Then:

$2750 = -25(90) + b$

$b = 5000$

Hence, the equation is:

$y(t) = -25t + 5000$ .

Item b:

Time is in seconds, hence, this is y(120).

$y(120) = -25(120) + 5000 = 2000$

The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.

Item c:

The time it takes to reach the ground is t for which y(t) = 0, hence:

$-25t + 5000 = 0$

$25t = 5000$

$t = \frac{5000}{25}$

$t = 200$

It takes 200 seconds for the skydiver to reach the ground.
