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

Answer:

( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )

Step-by-step explanation:

[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5

(Multiply 3 from [tex]3x^{2}[/tex] with -5)

Product = -15

Sum = -2

(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)

[tex]3x^{2}[/tex] + 3[tex]x[/tex] - 5

3[tex]x[/tex] ( [tex]x[/tex]  + 1 ) - 5 ( [tex]x[/tex] + 1 )

= ( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )

Answer:

Step-by-step explanation:

Draw the altitude from the vertex angle to the base. You have two congruent, right triangles. The hypotenuse of each triangle is

√[(56/2)²+45²] = √[28²+45²] = √2809 = 53 mm

perimeter of larger triangle = 2×53 + 56 = 162 mm

Step-by-step explanation:

[tex] \frac{ \sin(81) }{51} = \frac{ \sin(b) }{11} \\ \sin(b) = 0.213 \\ b = 12.3 \: degrees = 12 \: degrees[/tex]

The answer is Sale Price = 100% - 36% = 64%

Sale Price is $32

64% = $32

-------------------------------------

Find 1 % :

-------------------------------------

64% = $32

1% = $0.50

-------------------------------------

Find 100% (Original Price) :

-------------------------------------

1% = $0.50

100% = $0.50 x 100

100% = $50

--------------------------------------------------------------------------

Answer: The original Price is $50.

------------------------------------------------------

Answer:

Answer: $50

Step-by-step explanation:

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.

what is the qns?????????

An equation in point-slope form to find the total distance y Izzy travels after x hours  5.92307 ft/sec

21 miles in 5.2 hours equals 4.7636363 mph.

21 mi / 5.2 hr = 4.0384613..... mi/hr

To convert now:

4.0384613 mph * 5280 feet per mile   1 hour and 3600 seconds

4.0384613 mi / hr * 5280 ft / mi * 1 hr / 3600 sec

Remove the units:

4.0384613 * 5280 feet / 3600 sec

We can eliminate 40:

4.0384613 * 132 ft / 90 sec

We can factor in an additional 6:

5.92307= 4.0384613 * 22 ft/ 15 sec

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.

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

Answer:

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
