If you multiply my number by -4 and subtract 20, the result is 8. What’s my number?

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

we have given that

Area  = 62 square centimetres.

What is the formula for the area of circle

[tex]A=\pi r^{2}[/tex]

A=62 and pi=3.14

[tex]62=3.14r^{2}[/tex]

find the value of r square divide both side by 3.14

[tex]r^2=\frac{62}{3.14}[/tex]

[tex]r^2=17.75\\[/tex]

[tex]r=4.21cm[/tex]

[tex]circumference of circle =2\pi r[/tex]

[tex]C=3.14)(4.21)\\\\C= 2 (13.22) \\\\C= 26.44.cm[/tex]

Therefore we get,

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

[tex]x^2 = 6^2 + 8^2[/tex]

[tex]x^2 = 36 + 64[/tex]

[tex]x^2 =100[/tex]

Take positive square root of both sides

[tex]x = \sqrt{ 100[/tex]

[tex]x = 10[/tex]

Jennifer might be landed on 33 of the number line.

A number system is defined as a system of writing to express numbers.

She starts at -19 and then moves to 9

-19 to 9 is 28 steps

19+9=28 steps

From 9 she walks to -15, turns around and walks to 16.

9+15=24 steps

From -15 to 16 she walks

15+16=31 steps

The total number of steps

28+24+31=83 steps

she wants to have a total of 100 steps,

100-83 leaves 17 steps left

Currently on 16 so add or subtract 17

16+17=33 and 16-17=-1

Hence Jennifer might be landed on 33 of the number line.

Answer:

0.17 over 1

Step-by-step explanation:

So, first we have to find a comman factor. between 255, and 15 the GCF is 15, so 255 ÷ 15 = 17      So that is:

            255 ÷ 15 = 17                

Now we move the decimal into place so its $0.17 becaue 0.17 x 15 = 2.55

Answer:

Step-by-step explanation:

The mnemonic SOH CAH TOA can remind you of the relevant relationships. The given side is the hypotenuse. x is the side opposite the given angle.

  Sin = Opposite/Hypotenuse

  sin(51°) = x/(9 ft)

  x = (9 ft)sin(51°)

  x ≈ 6.99 ft

__

  Cos = Adjacent/Hypotenuse

  cos(51°) = y/(9 ft)

  y = (9 ft)cos(51°)

  y ≈ 5.66 ft

Answer: B you multiply 4 times 10 add it to 6 which is 46/10 it’s how you convert a improper fraction to a mixed number

Step-by-step explanation:

Answer:

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = [tex]\frac{7\sqrt{3} }{x}[/tex]

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.

Answer:

$48

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = 200 × 0.08 × 3 = 48

I = $ 48.00

The simple interest accumulated

on a principal of $ 200.00

at a rate of 8% per year

for 3 years is $ 48.00.

7x = -42

Divide.

x = -6

good luck, i hope this helps :)

Answer:

-6

Step-by-step explanation:

4x-2+3x-7=-51

we take minus two to the other side and it becomes plus two and -51+2 is -49

4x+3x-7=-49

and we take minus seven to the other side it becomes plus seven and -49+7 iis -42

4x+3x=-42

4x+3X = 7x

7x = -42

and to remove the x we divide both sides by 7

x = -42/7

-42/7 = -6

x=-6
