The volume of a prism is 8000 mm3. What is the volume of this prism, measured in cm3?

1 answer:

7 0

1meter=1000milimeter
1meter=100centimeter
1000milimeter=100centimeter
1cm=10mm
1cm^3=1000mm^3
8000mm^3 * 1cm^3/(1000mm^3) = 8 cm^3
hopes this gains.

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

Lexie is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide. If the field in Lexie’s drawing is 3

timurjin [86]

Answer:

The field in Lexie's drawing should be 20 cm long.

Explanation:

Making a scale drawing requires that the figure be similar, which implies that the sides of the figures be proportional.

The proportion for a drawing 30 cm wide and unknown length with the soccer field that is 120 yards long and 80 yards wide is:

length of the drawing / width of the drawing = length of the field / width of the field

Thus, using x for the unknown width of the drawing:

30 cm / x = 120 yard / 80 yard

Thus, you must solve for x:

30 cm × 80 yard = 120 yard × x

x = 30 cm × 80 yard / 120 yard = 20 cm.

Hence, the field in Lexie's drawing should be 20 cm long.

Paul can walk 15 steps in 5 minutes. How long does it take Paul to walk 75 steps at the same speed? I got 25 minutes am i right?

lina2011 [118]

The best way to solve this one is with a proportion:

(15 steps) / (5 minutes) = (75 steps) / ('x' minutes)

Cross-multiply the proportion: 15 x = 5 x 75

Divide each side by 15 : x = 5 x 5 = 25 minutes.

You are correct, and Paul walks very slowly.
