Answer:

Diameter = 23  Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

<em>72.22 ÷ 3.24 = 23</em>

diameter = 23

Divide the diameter by 2.

<em>23 ÷ 2 = 11.5</em>

There you go, you found the circle's radius

How do you do factoring the gcf out of a binomial
iVinArrow [24]
In general: look for what the terms have in common. for example, take the binomial 2x² - 4x. you would be able to factor out a "2" because of the coefficients, and both terms have an "x" -- you can take that out too. that makes your GCF 2x. technically, what you're doing with factoring is dividing the terms by your GCF--2x² divided by 2x leaves you with x, and 4x divided by 2x leaves you with two. that's how you end up with (x - 2) in your binomial. your result looks like this: 2x(x - 2).

if you have any specific binomials you need help with, feel free to send me a message or comment on this and i'll see if i can help. if you're just asking in general, then just remember to look for what the terms have in common, then take it out.

A line contains the points (3, -4) and (0, 2). What is the equation of this line in slope-intercept form?
Lera25 [3.4K]

Answer:

B. y = –2x + 2

Step-by-step explanation:

First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

-y₁ + y₂\-x₁ + x₂ = m

\frac{4 + 2}{-3 + 0} = -\frac{6}{3} = -2

In this case, the y-intercept of [0, 2] is ALREADY given to you, so we would not have to go further.

I am joyous to assist you anytime.

Write as ratio in simplest form<br><br> 91%, 12%, 6%, 93%, 62%, 14%, 70%, 400%,.
jolli1 [7]
A)
91/100
we cannot simplify this

b) 12/100 = 6/50
cannot be simplified further

c) 6/100 = 3/50

d) 93/100
cannot be simplified

e) 62/100 = 31/50

f) 14/100 = 7/50

g) 70/100 = 7/10

h) 400/100 = 4

when something is in percentage that means it is some part of 100% that is why we divide by 100.
