Leilani practiced piano for 3/5 of an hour. Sarah practiced piano for 7/8 of an hour.

ivolga24 [154]

Answer:

The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours .

Step-by-step explanation:

Given as :

The time for which Leilani practiced piano = $\dfrac{3}{5}$ hours

The time for which Sarah practiced piano = $\dfrac{7}{8}$ hours

Let the number of hours did Sarah practice more than Leilani = T hours

Now, According to question

The number of hours did Sarah practice more than Leilani = $\dfrac{7}{8}$ hours - $\dfrac{3}{5}$ hours

Or, T = $\dfrac{35-24}{40}$ hours

Or, T = $\dfrac{11}{40}$ hours

So,The number of hours did Sarah practice more than Leilani = T = $\dfrac{11}{40}$ hours

Hence, The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours . Answer

Find the equation for the line that passes through the point (2,2), and that is parallel to the line with the equation y=3/4x-4

telo118 [61]

Answer: y=3/4x + 1/2

Step-by-step explanation: Parallel lines must have the same slope, so you already know the equation must be something like y=3/4x+b. You are given a point that the line goes thru(2,2), so you can plug this point into the equation to solve for b.

(2)=3/4(2) + b

2=6/4 + b

2= 3/2 + b

b= 2-3/2

b=4/2- 3/2

b=1/2

so y=3/4x + 1/2

The braking distance, in feet of a car a Travling at v miles per hour is given.

irakobra [83]

The braking distance is the distance the car travels before coming to a stop after the brakes are applied

a. The braking distances are as follows;

The braking distance at 25 mph, is approximately 63.7 ft.

The braking distance at 55 mph, is approximately 298.35 ft.

The braking distance at 85 mph, is approximately 708.92 ft.

b. If the car takes 450 feet to brake, it was traveling with a speed of 98.211 ft./s

Reason:

The given function for the braking distance is D = 2.6 + v²/22

a. The braking distance if the car is going 25 mph is therefore;

25 mph = 36.66339 ft./s

$D = 2.6 + \dfrac{36.66339^2}{22} = 63.7 \ ft.$

At 25 mph, the braking distance is approximately 63.7 ft.

At 55 mph, the braking distance is given as follows;

55 mph = 80.65945 ft.s

$D = 2.6 + \dfrac{80.65945^2}{22} \approx 298.35 \ ft.$

At 55 mph, the braking distance is approximately 298.35 ft.

At 85 mph, the braking distance is given as follows;

85 mph = 124.6555 ft.s

$D = 2.6 + \dfrac{124.6555^2}{22} \approx 708.92 \ ft.$

At 85 mph, the braking distance is approximately 708.92 ft.

b. The speed of the car when the braking distance is 450 feet is given as follows;

$450 = 2.6 + \dfrac{v^2}{22}$

v² = (450 - 2.6) × 22 = 9842.8

v = √(9842.2) ≈ 98.211 ft./s

The car was moving at v ≈ 98.211 ft./s
