REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
Answers
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Find the first two terms of the geometric sequence.
Answers
Answer:
125, 100, 80,64,51.2,40.96...
Step-by-step explanation:
y=[tex]\frac{4}{5}[/tex]x
So let's work backwards!
[tex]\frac{5}{4}[/tex](80)
=100
Then...
[tex]\frac{5}{4}[/tex](100)
=125
Hope this helps! :D
Answer:
125, 100
Step-by-step explanation:
Perhaps the terms of your series are supposed to be ...
__, __, 80, 64, 51.2, 40.96, ...
The common ratio is 64/80 = 0.8, so the recursive relation is ...
t[n] = 0.8×t[n-1]
__
Solving for the previous term, we find ...
t[n]/0.8 = t[n-1] . . . . . . divide by 0.8
or ...
t[n-1] = 1.25×t[n] . . . . . rearrange
Then the term previous to 80 is 1.25×80 = 100.
And the term previous to 100 is 1.25×100 = 125.
The first two terms of the geometric sequence are 125 and 100.

Given:
∠1 = 63 - 2x°∠2 = 72 - 3x°And if we look at the diagram, we can see that angles 1 and 2 are corresponding, and corresponding angles are congruent(meaning they measure the same degrees).
So all we need to do now, is set up the equation to angle 1 being equal to angle 2.
(63 - 2x) ← [angle 1] = (72 - 3x) ← [angle 2]
Solve;
63 - 2x = 72 - 3x
+2x +2x
63 = 72 - 1x
-63 -63
9 - 1x = 0
+1x +1x
9 = x, the value of 'x' measures 9°.

Answer:
x = 15, y = 5
Step-by-step explanation:
total score of A = 6x
total score of B = 25*8 = 200
total score of C = 20y
(6x+200)/(x+25)=7.25
6x+200 = 7.25x+181.25
18.75 = 1.25x
x = 15
and
(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5
plug in x
(290+20y)/60 = 6.5
290 + 20y = 390
20y = 100

Michael decided to take all his leftover change each month and place it into a savings account. This account earns 2% simple interest each year. The only thing Michael is putting in this account is his leftover change, which is a small amount. Should Michael keep his account since he is putting very small amounts in and earns very little interest?
A. Yes, his monthly deposits and interest will accumulate, which means the balance will grow over time.
B. No, the monthly bank fees are taking away all his deposits which leaves the account at zero.
C. Yes, the cost to close the account would cost more than what is in the account since the acc
ount balance really isn't growing.

Answer:
-0.58
Step-by-step explanation:
The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.
I hope this helps and please mark me as brainliest!
Answer:
-0,56
Step-by-step explanation:
As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6
So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.
Another way of putting this is you must add 0.02.
For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02
First notch: -0.6 + 0.02 = -0.58
Answer: Second notch: -0.58 + 0.02 = -0,56
A skateboard was originally priced at $53.00. It is on sale for 15% off. What is the sale price of the skateboard?
Answers
Answer:
$45.05
Step-by-step explanation:
To find 10% divide the original number by 10. This is $5.30
To find 5% divide 10% by 2. This is $2.65
Add the two together to get 15%. This is $7.95
Take away the value of 15% from the original number.
$53.00 - $7.95 = $45.05
