Answer:

The train travels at 120 miles per hour.

Step-by-step explanation:

All we have to do is divide 540 by 4.5

540 ÷ 4.5 = 120

So the answer is 120 miles per hour.

Hope this helps! :)

Find the volume If the rectangular prism of this 3m,11m,3m and what is the answer

sveta [45]

Answer:

99 m³

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated using the formula

V = lbh

where l is the length, b the breadth and h the height, hence

V = 3 × 11 × 3 = 99 m³

What is the value of tanØ

mr_godi [17]

Answer:

tan ∅ = 24 / 7

Step-by-step explanation:

cos ∅ = 7 / 25

sin^2 ∅ + cos^2 ∅ = 1

sin^2 ∅ + (7 / 25)^2 = 1

sin^2 ∅ = 1 - 49 / 625

sin^2 ∅ = 625 - 49 / 625

sin^2 ∅ = 576 / 625

sin ∅ = root 576 / 625

sin ∅ = 24 / 25

tan ∅ = sin ∅ / cos ∅

tan ∅ = 24/25 / 7/25

Therefore, tan ∅ = 24 / 7

OPTION 4. 24 / 7

△HFM∼△PST

loris [4]

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

The correct picture of the question in the attached figure

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

we have

△HFM∼△PST ----> given problem

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{HF}{PS}$

substitute the given values

$z=\frac{14}{8}=1.75$

step 2

Find the perimeter of triangle PST

Remember that the perimeter of a triangle is the sum of its three length sides

$P=8+9+12=29\ units$

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

$29(1.75)=50.75\ units$
