Answer:

13.448, rounded off: 13.5 ft

Step-by-step explanation:

[tex]r=\frac{C}{2\pi }[/tex]

Where r = radius, C = circumference.

[tex]r=\frac{84.5}{2\pi } =13.448[/tex] = 13.5 ft

Answer:

r = 13.5 ft

Step-by-step explanation:

The circumference of a circle of radius r is C = 2(pi)r.

Here, C = 84.5 ft = 2(pi) r, or

          C = 84.5 ft = 6.28r

Dividing both sides by 6.28 results in the value of r:

r = 84.5 ft / 6.28 = 13.5 ft

Step-by-step explanation:

Use the formula for compound interest

f/p: f =p(1+i)^n

p = 3300

i =8% = 0.08

n = 9 years

A = p(1+r)^t

A = 3300(1+0.08)⁹

A = 3300× 1.99

A= 6596.71 dollar ~ 6597 dollar.

and set up proportions

[tex] \frac{ba}{ac} = \frac{h}{rt} [/tex]

solve for h

Answer:

Step-by-step explanation:

assuming that the triangles are similar,  which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this,  it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

Answer:

two solutions at 2/3 and 1/4

Step-by-step explanation:

12q² - 11q + 2 = 0

(3q - 2)(4q - 1) = 0

3q = 2

q = 2/3

4q = 1

q = 1/4

Answer:

Answer = D

Step-by-step explanation:

If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

I hope this helps have a good day :)

The typical second-grade student is about 48 inches tall.

'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'

According to the given problem,

Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }

Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52

                                     = 480

Average of the given heights = [tex]\frac{480}{10}[/tex]

                                                 = 48

Hence, we can conclude,  The typical second-grade student is about 48 inches tall since the average of the given data is 48.
