What is the area of this figure?
(Use = 3.14 and round to two decimal places.)
0.1 cm
Answers
Answer:
the area of above figure is 0.31 cm^2
Answer:
A ≈ 0.03 cm²
Step-by-step explanation:
Area of a circle = πr²,
where π (pi) ≈ 3.14 or 22/7 as a close fraction is the ratio (factor) between the circumference and the diameter (2 times / twice the radius),
and r² is the radius squared or multiplied by itself once.
Given that the radius is 0.1 cm in this situation,
the area of this circle is as follows:
A = πr² → A = π (0.1)² cm² → π(0.01) cm² → 0.01π cm² →
(1/100)(π) cm² → π / 100 cm² → 3.14 / 100 cm² →
0.0314 cm² ≈ 0.03 cm²

If a+b = c which of the following statements is true?
b-c=a
a-c=b
c-a=b
c+b= a
Answers
Answer:
c-a=B
Step-by-step explanation:
if A+B=c then you subtract a from c and you get b
Answer:
C. c - a = b
Step-by-step explanation:
a + b = c
There are many ways to rearrange this equation. This can be done through addition and subtraction.
First, let's handle a. a is positive; therefore, we should subtract it.
a + b = c
b = c - a
Next, let's handle b. b is also positive; therefore, we should subtract it.
a + b = c
a = c - b
Finally, we will handle c. c is once again positive; therefore we should subtract it. However, it is the only variable on the right side, which would leave 0. This is not an option, so we will not look at this.
From our options, we can see that we have produced: b = c - a
This is an option, which has been written as c - a = b.
Therefore, your answer is C. c - a = b

Javon's first 3 quizzes had a mean score of 90%. If he scores 46% on his next quiz,what will be his mean quiz score for these 4 quizzes?
Answers
Answer: 79%
Step-by-step explanation:
Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:
= 90% × 3
= 270%
Since he scores 46% on his next quiz, we add it to the previous score and this will be:
= 270 + 46
= 316
Then, his mean quiz score for these 4 quizzes will be:
= Total score / Number of quizzes
= 316 / 4
= 79%
Answer:
79%
Step-by-step explanation:
316 / 4 = 79%

Plz help me do this. Thank you in advance. Do the ordered pairs as well :)
Answers
Answer:
y=3*(-2)
y=--(3*2)
y=-6
y=-6
y=0x-6
y=0x+(-6)
y=0x+(-6),m=0
y=0x+(-6),m=0,b=-6
m=0,b=-6
y=3x(-2)
Let x be the domain values.
Let x = -1
y = 3(-1) - 2
y = -6 - 2
y = -8...range
Our first ordered pair is (-1, -8).
Let x = 2
y = 3(2) - 2
y = 6 - 2
y = 4...range
Our second ordered pair is (2, 4).
Let x = 4
y = 3(4) - 2
y = 12 - 2
y = 10...range
Our third ordered pair is (4, 10).
Done.

Paul finished his 800 meter race in 2 minutes and 2 seconds. Jeff finished in 121 seconds. Who finished first? (PLESES SHOW WORK)
Answers
Answer:
Jeff finished first
Step-by-step explanation:
To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes
CONVERT 2 MINUTES 2 SECONDS TO SECONDS
60 seconds = 1 minutes
to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it
2 x 60 = 120 seconds
120 seconds + 2 seconds = 122 seconds
Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first
CONVERT 121 SECONDS TO MINUTES
60 seconds = 1 minutes
To convert 121 seconds to minutes, we have to divide by 60
121/60 = 2 minutes 1 second
Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first
For his birthday, Mr. Robin and four of his friends went to a Math museum to learn about new intergalactic math. They each got a ticket for $12.00 and each bought the same calculator at the gift shop. If Mr. Robin spent $110 for the group's tickets and calculator, how much did each calculator cost? Write and solve an equation to describe this situation.
Answers
Answer: $10
Step-by-step explanation:
Given
Robin and his four friends bought tickets for [tex]\$12[/tex] each
If each one of them bought a calculator then the total spendings are [tex]\$110[/tex]
Suppose the cost of each calculator is [tex]\$\ x[/tex]
Cost per person is given by [tex]x+\$12[/tex]
For the group, it is [tex]5(x+12)[/tex]
Equate this to total spendings
[tex]\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10[/tex]
thus, the cost of each calculator is [tex]\$ 10[/tex]

Becky borrowed $580.00 from the bank. The loan had a 13.5% simple annual interest rate, and she paid off the bill over 1.5 years. What was the total amount, including interest, Becky paid for the loan?
Answers
Answer:
697.45
Step-by-step explanation:
interest for the first year = 13.5 % of 580 = 78.3
for 0.5 year, it will be 78.3 /2 =39.15
1year + 0.5 year = 78.3 + 39.15= 117.45
add that to borrowed amount to get total amount paid
117.45+ 580= 697.45
