A 2​-ft vertical post casts a 20​-in shadow at the same time a nearby cell phone tower casts a 125​-ft shadow. How tall is the cell phone​ tower?

Answers

Answer:

1249. 5 inches

Step-by-step explanation:

Pole length , Pl = 2 fts

Pole shadow, Ps = 20 in = (0.0833 * 20) = 1.666 ft

Tower length, Tl = 125 ft

Tower shadow, Ts = x

Pl / Ps = Tl/ Ts

2/ 1.666 = 125 / x

Cross multiply

2x = 125 * 1.666

2x = 208.25

x = 104.125 ft

x = 104.125 * 12 = 1249. 5 inches

The momentum of a variable is represented by the rate of change. The rate of change for the situation is 3 miles per hour.

What is the rate of change?

The momentum of a variable is represented by the rate of change, which is used to quantitatively express the percentage change in value over a specific period of time.

Given the distance covered in one hour is 3 miles, while the distance covered in 2 hours is 6 miles. In the given case, the rate of change for the situation, therefore,

Rate of change = (6miles-3miles)/(2hours-1hour) = 3miles/hour.

Hence, the rate of change for the situation is 3 miles per hour.

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?

Answers

Answer: Greater than 10 N

Step-by-step explanation:

Given

Gravity force on metal is 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

[tex]\Rightarrow F>10\ N[/tex]

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement

Apple juice and cranberry juice have been mixed in the ratio of 4:5. If the price of apple juice is 45 cents per pint and the price of cranberry juice is $0.8 per pint, what should the price of one pint of the mixture be?

Answers

Answer:

$0.24

Step-by-step explanation:

The computation of the price of the one pint of the mixture is shown below:

Since the ratio of apple juice and cranberry juice is 4:5

And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷  9 = 0.2

Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04

SO, the price of one pint of the mixture is

= 0.2 + 0.04

= $0.24

Answers

Answer:

The sale price of the shoes is $55.96

Step-by-step explanation:

1: 30% of $79.95 is 23.985.

Which would round to $23.99.

Then subtract 23.99 from 79.95.

79.95-23.99= 55.96

m∠ABC = 130°

Step-by-step explanation:

BD is the angle bisector of angle ABC .

Therefore, ∠ABD ≅ ∠DBC

Measure of angle DBC = 65°

Therefore, m∠ABD = m∠DBC = 65°

m∠ABC = m∠ABD + m∠DBC

Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.

The radius of a circle is 4 centimeters. What is the angle measure of an arc bounding a sector with area 2​ square centimeters?

Answers

Answer:

Measure of the arc = 14.32°

Step-by-step explanation:

Radius of a circle = 4 cm²

Area of the circle = πr²

Here, r = radius of the circle

Area of the circle = π(4)²

                             = 16π cm²

                             = 50.265 cm²

Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]

Here, θ = Central angle subtended by the arc Or measure of arc

Area of the sector given as 2 cm²

2 = [tex]\frac{\theta}{360}(50.265)[/tex]

θ = 14.32°

Therefore, measure of the arc = 14.32°.
