If anyone can help me answer this it would be great thx

Answer 1

Answer: ok so remember
area=pir^2
area=256pi

256pi=pir^2
divide both sides by pi
256=r^2
squaer root
16=r

find r and d
d=2r
d=2(16)
d=32

radius=16ft
diameter=32ft

Answer 2

Answer: RADIUS:A=3.14*r^2
area=256pi

256*3.14=3.14*r^2
divide both sides by 3.14
256=r^2
square root
16=r

DIAMETER:
3.Now double the radius to get the diameter.32 is the diameter.

radius=16ft
diameter=32ft

X - 3X = 2(4+X)

Distributive Property:

Division Property:

x = 8/-4

X = -2

Hi,

Let's solve the equation step-by-step.

x−3x=2(4+x)

Step 1: Simplify both sides of the equation.

x−3x=2(4+x)

x+−3x=(2)(4)+(2)(x)(Distribute)

x+−3x=8+2x

(x+−3x)=2x+8(Combine Like Terms)

−2x=2x+8

Step 2: Subtract 2x from both sides.

−2x−2x=2x+8−2x

−4x=8

Step 3: Divide both sides by -4.

−4x/−4 = 8/−4

x=−2

Answer:

x=−2

There are four more girls than boys in Ms. Raub's class of 28 students. What is the ratio of number of girls to the number of boys in her class?

Answers

Let the number of boys be x

Let the number of girls be x + 4

(x + 4) + x = 28

x + x + 4 = 28

2x + 4 =28

2x = 28 - 4 → 2x = 24 → x = 24 / 2 → x = 12

The number of boys is 12, so the girls are 12 + 4 = 16

Ratio of girls to boys → 16 : 12 → 4 : 3

Ratio of girls to boys is 4:3

Pythagorean theorem: Show work please

Answers

so if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7

The therorem is:

$a^(2) + b^(2) = c^(2)$
or, solving for b:
$b = \sqrt{c^(2)-a^(2)}$

$b = \sqrt{20^(2)-15^(2)}$
$b = √(400-225)$
$b = √(175)$
$b \approx 13.23$

8374 exponential notation

Answers

Expanded for of 8,374 is:

8000 + 300 + 70 + 4

And writing it with the exponential notation would look like this (for example):

8 * 10^3 + 3 * 10^2 + 0.7 * 10^2 + 0,04 * 10^2

Hopefully that's what you meant :)
