what is 15% of 80? use an equation to solve.​

Answers

Answer 1

Answer:

12

15. percent *80 =

(15.:100)*80 =

(15.*80):100 =

Find the area of the inner and the outer circles, shown in the figure below. Use 3.14 for pi.


Answers

The radius of the outer circle is 17 so you put that in the formula to find the area of a circle and solve to get 153.86 squared meters as the final answer. The radius of the inner circle is 7 because it shows that the upper part of the circle is 10 and the whole thing is 17, so you do 17-10 to get 7 as the radius. Then put it in the formula and get the final answer as 907.46 squared meters.

On a map, the distance between Louisville, Kentucky, and Nashville, Tennessee, is 1 3/4 inches. The scale of the map is 1 in:100 mi. What is the actual distance between the two cities?​

Answers

Answer:

Step-by-step explanation:

The distance between 2 cities is 175 miles

What is scale on graph?

A scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data.

Given data ,

The distance between Louisville and Nashville = 1 3/4 inches

Scale of the map = 1 in : 100 miles

Now , 1 inch = 100 miles on the map

And , 1 3/4 = 7 / 4 inches

So , 7 / 4 inches = ( 7 / 4 ) x 100 miles

                          = 1.75 x 100 miles

                          = 175 miles

Hence , the distance between 2 cities is 175 miles

How?
X+139=132 by the alternate interior angle rule so solve and get -7

21x+5= 23x-5 by the corresponding angles rule solve and get 5

20x+5+24x-1= 180 because when an angle is one a parallel line the sun of angle to the right or left of it is 180 solve and get 4

6x= 5x+10 by the corresponding angles rule solve and get 10

X+109+x+89= 180 because x+89 is equal to the angle that is too the right of x+109 by the alternate interior angle rule making the sum equal to 108. Solve and you get -9

Answer:

Approximately $0.10 per ounce

Step-by-step explanation:

Hi! :) I'm assuming this problem is asking for the price per ounce? If not, I apologize.

So, in order to determine the price of cereal per ounce we would simply divide $3.50 by 36 to find the cost per ounce.

$3.50 / 36 = approximately $0.09722222 which we can round up to $0.10.

A woman is standing 12 feet from a sculpture. The angle of elevation from her eyes to the top of the sculpture is 35º. If the woman's eyes are 5 feet 6 inches off the ground, how tall is the sculpture? Round answer to the nearest thousandth of a foot.

Answers

Answer:

13.903 feet

Step-by-step explanation:

Let the height from the woman's eyes to the top of the sculpture be represented by x.

So that,

Tan 35 = [tex]\frac{x}{12}[/tex]

x = Tan 35 x 12

  = 0.70021 x 12

  = 8.4025

x = 8.403 feet

The height of the sculpture = The woman's eye level to the ground + x

                                              = 5 feet 6 inches + 8.403 feet

                                              = 5.50 feet + 8.403 feet

                                              =  13.903 feet

Thus, the sculpture has a height of 13.903 feet.

PLEASE HELP, I DON'T UNDERSTAND THE WORDING​

Answers

Answer:

C. 8 miles per hour

Step-by-step explanation:

It takes Diego [tex]\frac{1}{8}[/tex] of an hour to complete the lap = [tex]\frac{1}{8}[/tex] x 1 hour = [tex]\frac{1}{8}[/tex] hour

Distance of the track = 1 mile long

The speed of an object expresses the ratio of distance moved to time taken to cover the distance.

i.e speed = [tex]\frac{distance}{time taken}[/tex]

           = [tex]\frac{1}{\frac{1}{8} }[/tex]

Speed = 8 mile per hour

Therefore, Diego's bike has a speed of 8 miles per hour.
