Answer:
66 cm (Option B)
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, so plug the values into the formula. The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5. Use 3.14 for π.
C = 2πr
C = 2(3.14)(10.5)
C = 6.28 × 10.5
C = 65.94
Rounded to the nearest unit, you get a answer of 66 cm.
Hope this helps! :)

x + 2y = 1 and 2x + 5y = 3.
Can someone help me , with process to please ?
I will appreciate thank you so much!
Answers
Answer:
x = -1
y = 1
Step-by-step explanation:
x + 2y = 1 (Multiply this by -2)
2x + 5y = 3
-2x - 4y = -2
2x + 5y = 3
y = 1
x + 2y = 1
x + 2(1) = 1
x + 2 = 1
x = 1 - 2
x = -1
Answer:
x = -1
y = 1
Step By Step Explanation:
x + 2y = 1
2x + 5y = 3
let x become the subject. use one of the equation.
x = 1 - 2y
substitute into another equation
2(1 - 2y) + 5y = 3
expend the bracket
2 - 4y + 5y = 3
collect like terms
- 4y + 5y = 3 - 2
y = 1
substitute into one of the equation to find x
x + 2y = 1
x + 2 (1) = 1
x + 2 = 1
collect like terms
x = 1 - 2
x = - 1
Ernesto has $70 in a savings account. The interest rate is 5%, compounded annually. To the nearest cent, how much will he have in 3 years?
Answers
Answer: $81.03
Step-by-step explanation:
The interest is compounded annually which means that the future value formula applies:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = $70
Rate = 5%
Number of years = 3 years
In 3 years, Ernesto will have:
= 70 * ( 1 + 5%)³
= $81.03
A triangle has two sides of length 14 and 17. What is the smallest possible whole-number length for the third side?
Answers
Answer:
The smallest possible length for the third side would be 36 whatever-the-nineteen-and-the-sixteen-unit.
Step-by-step explanation:
In a triangle, sides a+b>c, b+c>a So, we first add up the two known sides.
Now we know that "c" has to be greater than 35, the closest whole number would be 36. And because the smaller numbers, 19 and 16, are settled, we know just by the fact how just one number is greater than all of the others, using the rule that I listed from the beginning, that this will work.
Answer:
22
Step-by-step explanation:
a²+b²=c²
14²+17²=c²
c²=485
√c²=22.0227
c=22.0227
smallest whole number is 22

Answer:
y = 2.5 ft4y = 10 ftStep-by-step explanation:
The perimeter is the sum of the side length. Each of the sides shown has the same length as its opposite, so the perimeter is ...
P = 2(4y +y) = 10y
Using the given value for perimeter, we find y to be ...
25 ft = 10y
2.5 ft = y
__
Then the longer side is ...
4y = 4(2.5 ft) = 10 ft . . . . length of longer side

we have a and c
so substitute them in

the angles make up co-interior so the two would add up to 180º.
so we can set up a basic equation:

add 40 to both sides:
8x=220

Tamara earned an a on 5/8 of her spelling test of those spelling says she earned a perfect score on 1/5 of them find what fraction of cameras total spelling test did she on a perfect score show your work
Answers
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
Step-by-step explanation:
Tamara earned an A in 5/8 of all the tests she took.
In 1/5 of the those tests she got an A, she had a perfect score.
1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.
That means that in 1/8 of all tests she took she got a perfect score.
She took a total of 32 spelling tests.
1/8 of 32 = 1/8 * 32 = 32/8 = 4
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests

what is 2x + 20 + 2x = 60
Answers
Answer:
= 1 0
Step-by-step explanation:
Solve
1. Combine like terms
2 + 2 0 + 2 = 6 0
4 + 2 0 = 6 0
2. Subtract 20 from both sides of the equation
4 + 2 0 = 6 0
4 + 2 0 − 2 0 = 6 0 − 2 0
3. Simplify
Subtract the numbers4 + 2 0 − 2 0 = 6 0 − 2 0
4 = 6 0 − 2 0
Subtract the numbers4 = 6 0 − 2 0
4 = 4 0
4. Divide both sides of the equation by the same term
4x = 40
4x/4 = 40/4
5. Simplify
Cancel terms that are in both the numerator and denominator4x/4 = 40/4
x = 40/4
Divide the numbersx = 40/4
x = 10

For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
A. n = 65; p = 0.9
O B. n = 35; p = 0.9
C. n = 35; p = 0.8
O D. n = 65; 6 = 0.8
Answers
Answer:
n = 65; p = 0.8
Step-by-step explanation:
The sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution is n = 65, p = 0.8.
The correct option is D.
According to the Central Limit Theorem, the shape of sample distribution of sample proportions with a population proportion, 'p' is normal
If n·p ≥ 10 and n·(1 - p) ≥ 10.
n = 65, p = 0.8
∴ n·p = 65 x 0.8 = 52 > 10
n·(1 - p) = 65 × (1 - 0.8) = 13 > 10
For n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution.
