Answer:

70

Step-by-step explanation:

14*100/20

14* 100= 1400

1400/20= 70

The percentage is a certain proportion of a number. 14 is 20[tex]\%[/tex] of 70.

Percentage is a way of expressing a fraction or proportion out of 100. It is represented by the symbol "%". The word "percent" comes from the Latin phrase "per centum," which means "per hundred."

Percentages are commonly used to describe ratios, rates, or proportions in various fields such as mathematics, finance, statistics, and everyday life. They allow us to compare quantities or express relative changes easily.

Let x be the number whose 20[tex]\%[/tex] is 14.

Then,

20[tex]\%[/tex] of x = x [tex]\times \ \frac{20}{100}[/tex] = 14,

x [tex]\times \ \frac{1}{5}[/tex] = 14,

x = 14 [tex]\times\ 5[/tex],

x = 70.

So, 20[tex]\%[/tex] of 70 is 14.

Answer:

Part a) The equation that represent the depreciation is [tex]y=18,000(0.88)^{x}[/tex]  

Part b) The value of the car in 8 years is [tex]\$6,473.42[/tex]  

Step-by-step explanation:

Part a)

we know that

The  formula to calculate the depreciated value  is equal to  

[tex]y=P(1-r)^{x}[/tex]  

where  

y is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

[tex]P=\$18,000\\r=12\%=0.12[/tex]

substitute in the formula

[tex]y=18,000(1-0.12)^{x}[/tex]  

[tex]y=18,000(0.88)^{x}[/tex]  ------> equation that represent the depreciation

Part b) Find the value of the car in 8 years

Substitute the value of [tex]x=8\ years[/tex] in the equation and solve for y

[tex]y=18,000(0.88)^{8}=\$6,473.42[/tex]  

Answer:

19 mm

Step-by-step explanation:

A penny is not that large, and you can fit multiple pennies in the palm of your hand. This means that the only reasonable measurement is 19 mm, (& 8 cm, but that is only if you have really large hands). Therefore, (A) is your choice.

~

The most accurate measurement for the width of a penny is 19 mm. Millimeters are the most precise unit on a standard meterstick for such a small measurement.

The most accurate measurement to describe the width of a penny is 19 mm. A penny is approximately 19 millimeters wide, or 1.9 centimeters (cm). When measuring objects, it is important to use the most precise unit available. In the case of a penny, millimeters provide a more exact measurement than centimeters, which are more precise than meters. Kilometers (km) are used for much larger distances and would not be appropriate for measuring a small object like a penny.

This understanding is based on established scientific conventions for communicating the degree of precision of a measurement, which depend on the smallest marking available on the measuring device. In the absence of smaller markings than millimeters on a typical measuring device like a meterstick, an estimation to the next decimal place is allowed for slightly more precision.

1 millimeter (mm) = 0.001 meter (m)

1 centimeter (cm) = 0.01 meter (m)

1 meter (m) = 3.28 feet (ft)

1 kilometer (km) = 1,000 meters (m)

I think the answer is 27 square feet.

18 square feet, I believe.

Answer:

The rate 37.5 miles per hour

The distance 150 miles

Step-by-step explanation:

∵ 1 mile = 1.6 kilometer

∵ The rate is 60 km/h

∴ The rate = (60 × 1) ÷ 1.6 = 37.5 miles per hour

∵ The car will travel for 4 hours

∴ The distance = 37.5 × 4 = 150 miles

Answer:

The dimensions of the dilated image are 60 cm by 32 cm

Step-by-step explanation:

we know that

The scale factor is equal to 4

The scale factor is > 1 -----> therefore the dilation is an enlargement

To find the dimensions of the dilated image, multiply the original dimensions by the scale factor

New Length=(15)(4)=60 cm

New Width=(8)(4)=32 cm

The dimensions of the dilated image are 60 cm by 32 cm

Answer:

Step-by-step explanation:

Three

Sum of all numbers beginning at 0 up to 2200 that are divisible by 3

a = 3

d = 3

L = 2199

Now we need to find out how many there are.

L = a1 + (n - 1)*d

2199 = 3 + (n-1)*3             Subtract 3

2199 - 3 = (n - 1)*3            Divide by 3          

2196/3 = n - 1

732 = n - 1                        Add 1 to both sides

733 = n                    

Sum = (a + L)*n /2            Substitute the values

Sum = (3 + 2199)*733/2   Combine and Divide by 2

sum = (1101)*733               Multiply

Sum = 807033

Five

Go through exactly the same steps.

a = 5

L = 2195  ( below 2200. You can't include 2200)

d = 5

L = a + (n-1)*d

2195 = 5 + (n-1)*5

2190 = (n - 1)*5

438 = n - 1

439 = n

Sum = (a + L ) * n

Sum = (5 + 2195)*439/2

Sum = 1100 * 439

Sum = 482900

The value of a is 1

Step-by-step explanation:

* Lets talk about some facts in the circle

- If two chords equal in length, then they are equal in measure

 or if they are equal in measure, then they are equal in length

- All the radii of the circle are equal

* Lets look to the figure

∵ The measure of arc WV = 86°

∵ The measure of arc XY = 86°

∴ The two arcs equal in measure, then they are equal in length

∴ WV = XY

∵ WV = 28

∵ XY = 4a + 24

∴ 4a + 24 = 28 ⇒ subtract 24 from the both sides

∴ 4a = 4 ⇒ divide two sides by 4

∴ a = 1

The supplement of a 9 degree angle is 171 degrees.

Final answer:

The measure of the supplement of a 9 degree angle is 171 degrees, which is found by subtracting 9 degrees from 180 degrees.

Explanation:

The measure of the supplement of a 9 degree angle is the amount you would need to add to 9 degrees to reach a straight line, which is 180 degrees. This is calculated by subtracting the given angle from 180 degrees.

To find the measure of the supplement of a 9 degree angle:

Start with a straight line, which measures 180 degrees.

Subtract the given angle from 180 degrees: 180 degrees - 9 degrees.

This results in a supplement of 171 degrees.

Therefore, the supplement of a 9 degree angle is 171 degrees.

Answer:

h - 145 = 457

602 meters

Step-by-step explanation:

The original height of the helicopter is unknown.

Let h = original height of the helicopter.

The helicopter was originally at height h.

The helicopter descended 145 m.

Descending means going down, so it lost height, so we subtract 145 from the original height.

The helicopter is now at a height of h - 145.

The new height is 457 meters.

That means that h - 145 must equal 457.

The equation is

h - 145 = 457

This is a subtraction equation since the only operation is the subtraction on the left side.

To solve the equation, we want h alone on the left side. 145 is being subtracted from h. The opposite operation to subtraction is addition. If we add 145 to the left side, we get h - 145 + 145 which is just h. That's what we want. We must do the same operation to both sides of an equation, so we add 145 to both sides.

h - 145 + 145 = 457 + 145

h = 602

Since h stands for the original height, now we answer that the original height was 602 meters.

Each drill takes $44 in materials and $36 in labor.  So it costs the company ($44+$36)= $80 to MAKE one drill.  THEN they're ready to sell it.  

At the same time, the company has to pay $4,000 just to use the building to make the drills.

I can see at least two different questions here:

Question #1). How much does it cost the company if they MAKE 330 drills in one month ?

Materials and labor:  330 x ($80)  =  $26,400

Rent the building space:  $4,000

Total for the month:  $30,400

Question #2).  How many drills do they have to SELL just to pay back the amount they already spent to manufacture those drills ?

We can't answer that right now, because we don't know the PRICE they charge for each drill when somebody buys it.

Step-by-step explanation:

There are 5 coolers at the event - 3 popsicles, and 2 ice cream. If randomly selecting a cooler, that means there's a 3 in 5 chance you will get a popsicle, which simplifies to 0.6. So simply multiply the probability (0.6) by the amount of football players (50) to get the answer, which is that 30 football players will get a popsicle.

Answer: Close to 30 but not 30 will get a popsicle.

Step-by-step explanation:
