Answer:
you can divide the diameter by 2 or divide the circumference by 2pi
Step-by-step explanation:
If the circumference of a circle is given:
Let the radius be r.Say, that the circumference is given as C.By using the formula,[tex]2\pi \: r = C \\ = > r = \frac{C}{2\pi} [/tex]So, to find radius of a circle when circumference is given, we have to divide the circumference with 2π. Then, we will get the radius of the circle.Note : You have to consider π as 22/7 or 3.14. Or the value will be given in the question.If the diameter of a circle is given:
Let the radius be r.Let the diameter be D.By using the formula,2r = D[tex] = > r = \frac{D}{2} [/tex]Hence, if the diameter of a circle is given, we have to just divide the diameter with 2. Then we will get the radius of the circle.Hope you could get an idea from here.

Enrique has to pay 80% of a $200 phone bill. Explain how to use equivalent ratios to find 80% of $200.
(U need to write a paragraph)
Answer:
First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.

A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.

Answer:
The answer is c.
Step-by-step explanation:
Rate of change means slope, in C, the slope is 6. Whenever you see an equation like that and a number with x after it, that's the slope, or rate of change. On the graph, the rate of change is -3, on answer choice C, the slope is -6.

Step-by-step explanation:
The height of a free falling object is represented by the expression -16t2 + v02 + h0 where v o is the initial velocity of 80 feet per second. And h o is the initial height of 25 feet what is the height of the object at t = 2 seconds ( pls no fake answers )
Answer:
The height of the object after 3 seconds is 45 feets.
Step-by-step explanation:
The height of an object thrown into the air with an initial upward velocity of 63 feet per second is given as
Where, h(t) is height of the object in feet and t is the time in seconds.
We have to find the height of the object after 3 seconds. So, substitute t=3.
Therefore height of the object after 3 seconds is 45 feets.
Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9
Answer:
Equation: I believe its y=5/3x-13
Step-by-step explanation:
In the "y=5/3x+9" equation, 5/3 is the slope. You then take the slope (5/3) and the points (9,2) and add it to the equation "y+y1=m(x-x1)":
y-y1=m(x-x1)
distribute 5/3: y-2=5/3(x-9)
y-2=5/3x-45/3
y-2=5/3x-15
-add 2 on both sides-
y=5/3x-13
I might be wrong- but its worth a try ;-;
