Answer:

h = 13ft

Step-by-step explanation:

We can assume that the triangles are similar, so:

5 ft is to 26 ft as 2.5 ft is to h ft.

Which can be set up like this:

[tex]\frac{5}{2.5}=\frac{26}{h}[/tex]

We can cross multiply:

5h = (2.5) (26)

5h = 65

h = 13ft

H=13ft do the cross multiply method

At the end of the season, 4 basketball teams in a league are having a pizza party at a restaurant.


Team Number of People
Sharks 17
Wolves 21
Tigers 20
Hawks 17
Coaches 9

The restaurant manager suggests that they order one pizza for every 6 people. How many pizzas
should they order?

Answers

14 pizzas.

First, add up the numbers of players on each team and the coachesto get the total number of people eating.
17 + 21 + 20 + 17 + 9 = 84

Then, you can divide 84 by 6 to see how many pizzas: 84/6 = 14

If you’re teacher wants you to set it up as a ratio, it’s 6/1 = 84/x

Then you cross-multiply:
6x = 84
Divide both sides by 6
x = 14

Step-by-step explanation:

Problem One

Perimeter is in meters not square meters. The equation is

2*(6.8+x) + 2*12.5= 47                Remove the brackets. Combine like terms  

13.6 + 2x + 25 = 47

38.6 + 2x = 47                            Subtract 38.5 from both sides

2x = 47 - 38.6  

2x = 8.4                                      Divide by 2

x = 4.2

Answer D

Problem 2

This problem is asking that you calculate the perimeter of a swimming pool.

The two semicircles on the ends make a whole circle.

The diameter of the semicircles is obtained from the difference of the two given lengths.

The rectangle has a length of 12. The length of the rectangle and the 2 semicircles is 16. The difference is 4. You could divide this by 2 to get the radius. I would just leave it as the diameter.

So the perimeter is pi*d + 2 * 12 [there are 2 lengths]

Perimeter = 4*pi + 24

Perimeter = 12.56 + 24

Perimeter = 36.56

Answer A

Problem 3

This is the circle inside the square.

The radius of the circle = 9

The diameter of the circle and the length of square's side = 2*9 = 18

The area of the square = s^2  where s = 18

The area of the square = 18^2 = 324

The area of the circle = pi * 9^2 = 3.24 * 81 = 251.34

The area of the Shaded area = 324 - 251.34 = 69.66

Answer C

Problem 4

b1 = 5

b2 = 11.5

h = 4.5

Formula

Area = (b1 + b2 ) * 4.5/2

Area =  (5 + 11.5) * 4.5 /2

Area = 16.5 * 4.5 / 2

Area = 74.25/2

Area = 37.125

miles north before stopping for a 1 minute break. After his break he runs 4 miles east before taking a 2
minute break. Next he runs 5 miles southwest back to his home. What is his average speed if the route
without the breaks takes 57 minutes to complete?

Answers

Answer:

he's running 4/19 miles per minute or 12.6 miles per hour

Step-by-step explanation:

he is running 3 miles north, 4 miles east, and 5 miles southwest, a total of 12 miles

d = rt

12 = 57r

r = 12/57 or 4/19 (simplest form)

this is 4/19 miles per minute, multiply by 60 and it's about 12.6 miles per hour

The temperate in Anchorage, Alaska at 9am was at -2°F. At 9pm the temperature decreased 7°F. Write an expression that represents the difference between the temperature from 9am to the resulting temperature at 9pm. How do I write the expression?

Answers

T=(-7/12)t-2

Im calling temperature T and time t for our equation but they can just as easily be Y and X

In 12 hours time the temp decreased 7 degrees so to get the slope we went down 7 and over 12 making it -7/12 (since we went down)

The at the starting point of t=0 it’s already -2 F making that our “y intercept” T intercept in this case

y=mx +b

In our case y=T x=t m=-7/12 and b= -2
Replace them to get
T=(-7/12)t-2

A 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward. Find the height of the tree after 8 years. ​

Answers

Answer:

the tree will be 11.04 feet tall

Step-by-step explanation:

4 x 0.22 (22%) = 0.88

every year it grows 0.88 foot.

0.88 x 8 = 7.04

4 + 7.04 = 11.04 feet tall

sorry if this is wrong!

The height of the tree after 8 years will be 11.04 feet.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a  4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward.

The height after 8 years will be calculated as:-

4 x 0.22 (22%) = 0.88

Every year it grows 0.88 feet.

0.88 x 8 = 7.04

4 + 7.04 = 11.04 feet tall

Aliyah bought a car for $32,000. It is now worth $5000 less than half of what she purchased it for. To the nearest tenth of a percent , find the percent decrease in the value of the car.

Answers

32,000 x 0.5 = 16000

16000- 5000 = 11000

11000 / 32000= 0.34375

1- 0.344= 0.656

Answer : D

The percent decrease in the value of the car is 65.6%.

Given that,

The purchase value of the car is $32,000.

The worth of the car is now $5,000 that should be lower than the half of purchased value i.e.

= 50% of $32,000 - $5,000

= $16,000 - $5,000

= $11,000

Now the percentage of decrease in the value of the car is

[tex]= \frac {(\$32,000 - \$11,000)}{\$32,000} \\\\= \frac{\$21,000}{\$32,000}[/tex]

= 65.6%

Therefore we can conclude that the percentage of decrease in the value of the car is 65.6%.

Therefore, all the other options are incorrect.
