If 10 inches on a map represents an actual distance of 100 feet, then what

Ira Lisetskai [31]

According to the given conditions, state:

<h3>10 × 100 = 25 ÷ x</h3>

<em>If the fraction is defined, then the denominator cannot equal 0:</em>

<h3>x≠0</h3>

<em>Attach the inequality as the domain: x≠0</em>

<em>Reduce the fraction to the smallest term, canceling the greatest common factor: </em><em>1/10 = 25/x.</em>

<em>Multiply both sides of the equation by the common denominator:</em>

<h3>10x/10 = 25 × 10x / x</h3>

<em>Simplify the fractions: </em>x = 250

<em>Find the intersection:</em> x = 250

<em>get the result:</em><em> </em>x = 250

<em>Answer:</em> x = 250

<em>the actual distance would be 250 feet.</em>

PLEASE help me with this question!! I really need help!

alexdok [17]

Answer:

324π in²

Step-by-step explanation:

The surface area of a sphere = 4πr² ( r is the radius )

Calculate r using the volume (V) formula

V = $\frac{4}{3}$ πr³

Here V = 972π , thus

$\frac{4}{3}$ πr³ = 972π ( divide both sides by π )

$\frac{4}{3}$ r³ = 972 ( multiply both sides by 3 to clear the fraction )

4r³ = 2916 ( divide both sides by 4 )

r³ = 729 ( take the cube root of both sides )

r = $\sqrt[3]{729}$ = 9

Thus

surface area = 4π × 9² = 4π × 81 = 324π in²

A ball is launched at 30 meters per second (m/s) from a 20-meter tall platform. The equation for the object's height s at time t

Juliette [100K]

The maximum height the ball reaches is 65.92 m.

The time taken for the ball to reach the maximum height is 3.06 seconds.

The time taken for the ball to hit the ground is 6.12 seconds.

<h3>maximum height the ball reaches</h3>

The maximum height the ball reaches is calculated as follows;

s(t) = -4.9t² + 30t + 20

at maximum height, final velocity = 0

v = 0

ds/dt = -9.8t + 30 = 0

9.8t = 30

t = 30/9.8

t = 3.06 seconds

s(3.06) = -4.9(3.06)² + 30(3.06) + 20

s(3.06) = 65.92 m

Thus, the time taken for the ball to reach the maximum height is 3.06 seconds.

<h3>Time of flight of the ball</h3>

The time taken for the ball to hit is the total time of flight = 2 x 3.06 seconds = 6.12 seconds.

Thus, the maximum height the ball reaches is 65.92 m.

The time taken for the ball to reach the maximum height is 3.06 seconds.

The time taken for the ball to hit the ground is 6.12 seconds.

The blueprint of a pool has a scale of 2 inches equals 7 feet. The scale drawing is shown below. the length is 20 and the width

AlladinOne [14]

Answer:

Part A:

Blueprint 10 inches ⇒ Actual 35 feet

Blueprint 20 inches ⇒ Actual 70 feet

Part B:

The cost of the cover is $857.5

Step-by-step explanation:

Part A:

∵ The drawing scale is 2 inches for 7 feet

∵ The length = 20 inches and the width = 10 inches

∴ The actual length = (20 × 7) ÷ 2 = 70 feet

∴ The actual width = (10 × 7) ÷ 2 = 35 feet

Part B:

∵ The cost per square foot = $0.35

∵ The area of the pool = 70 × 35 = 2450 feet ²

∴ The cost of the cover = 2450 × 0.35 = $857.5
