Answer:
Step-by-step explanation:
The two formulas are essentially the same. Recall that 2r = d (and of course d = 2r). If you're given the diameter, d, use C = πd; if you're given the radius, use C = 2πr.

A box of 14 cookies costs $8. What is the cost of 1 cookie?
Answer:
A cookie costs $4/7
Step-by-step explanation:
Let's write an eqution in which X represents the cost of a cookie
14x=8
Now divide both sides by 14
[tex]x=\frac{8}{14}[/tex]
Now simplify by 2
[tex]x=\frac{4}{7}[/tex]
So a cookie costs $4/7

what is (-4, 6) and (0, 7) in slope intercept form? :) thank you
Answer:
y = 1/4x + 7
Step-by-step explanation:
(-4, 6) and (0, 7)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(7 - 6) / (0 - (-4))
Simplify the parentheses.
= (1) / (0 + 4)
= (1) / (4)
Simplify the fraction.
= 1/4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 1/4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 7). Plug in the x and y values into the x and y of the standard equation.
7 = 1/4(0) + b
To find b, multiply the slope and the input of x(0)
7 = 0 + b
Now, isolate b.
7 = b
Plug this into your standard equation.
y = 1/4x + 7
This is your equation.
Check this by plugging in the other point you have not checked yet (-4, 6).
y = 1/4x + 7
6 = 1/4(-4) + 7
6 = -1 + 7
6 = 6
Your equation is correct.
Hope this helps!

B. Using complete sentences, describe how the sale price can be found in two different ways.
Answer:.9 times P will also get you the sale price
Step-by-step explanation:p - 0.1p = sale price
0.9 times p = sale price

Which of the following is the best interpretation of the data displayed in the line plot below?
A. Small dogs weigh more than housecats.
B. The weights of small dogs are more consistent than the weight of housecats.
C. The housecats' weights have a higher mean and are more consistently centered around their mean.
D. The small dogs' weights have a higher mean and are more consistently centered around their mean.
Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.
Step-by-step explanation:
if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.
SD= 9.9
HC= 11
so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.
Answer:
C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Answer:
x =
Step-by-step explanation:
15x - 30 = -15
Add 30 to both sides
15x + 30 = 15
15x = 15
Divide both sides by 15
15x / 15 = 15
x = 1
