The radius of the sphere is 6 millimeters. Which equation can be used to find the surface area of the sphere? A sphere with a radius of 6 millimeters. S = 4 pi r squared = 4 (6) squared S = 4 pi r squared = 4 pi (12) squared S = 4 pi r squared = 4 pi (6) squared + 2 pi (6) S = 4 pi r squared = 4 pi (6) squared
9514 1404 393
Answer:
(d) S = 4 pi r^2 = 4 pi (6)^2
Step-by-step explanation:
The formula for the area of a sphere is ...
A = 4πr^2
Filling in the given radius value, we get ...
A = 4π·6^2

there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?
Answer:6 students remaining
Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.

Step-by-step explanation:
one quarter of a certain number added to one eighth of the same number is 12. What is the number
Answer:
32
Step-by-step explanation:
let the number be n , then
[tex]\frac{1}{4}[/tex] n + [tex]\frac{1}{8}[/tex] n = 12 ( multiply through by 8 to clear the fractions )
2n + n = 96
3n = 96 ( divide both sides by 3 )
n = 32
The number is 32

Solve the formula s=4pi r^2 for r
Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.

9514 1404 393
Answer:
-1/2048
Step-by-step explanation:
The Order of Operations tells you to evaluate each of the exponential expressions first. Then you do the division.
= (1/32) / (-64)
= -1/(32·64) = -1/2048
__
You can also rewrite the expression in terms of powers of 2.
2^-5/-4^3 = -1/((2^5)(2^2)^3) = -1/(2^5×2^6) = -1/2^11
= -1/2048
_____
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
4 = 2^2
2^5 = 32

please help me answer this question.. am giving brainliest
Step-by-step explanation:
We are going to use the following properties of logarithms to solve this problem:
[tex]\log{\dfrac{a}{b}} = \log{a} - \log{b}[/tex]
and
[tex]\log{ab} = \log{a} + \log{b}[/tex]
So we can rewrite the given equation as
[tex]\log{2x^3} - \log{x} = \log{\left(\dfrac{2x^3}{x}\right)} = \log{2x^2}[/tex]
Also,
[tex]\log{16} + \log{x} = \log{(16x)}[/tex]
So we can write
[tex]\log{2x^2} = \log{(16x)}[/tex]
or eliminating the log symbols, we get
[tex]2x^2 = 16x[/tex]
The solutions for the equation above are
[tex]x = 8\:\text{and}\: 0[/tex]

A park ranger hiked 3/4 mi to a lookout, another 5/7 mi to a bird's nest, and finally 5/14 mi to a campsite. How far did the park ranger hike?
Answer:
2 miles and 88 yards.
Step-by-step explanation:
4 has 2*2 as prime factors
5 is prime
10 has 2 and 5 as prime factors
Thus, the lowest common denominator will be 2*2*5
3/4=15/20
3/5=12/20
7/10=14/20
Now that we have three fractions with the same denominator, we can add the numerators
15+12+14=41
So 41/20ths
That’s 2 and 1/20th
So the final answer is 2 miles and 88 yards! :)

Please help me!!! I am doing this problem in the unit "Classifying Angles and Angle Addition Postulate"
Answer:
134°
Step-by-step explanation:
since BD bisects L ABC,
x/2 + 17 = x - 33
=> multiply by 2, we find:
x+34=2x-66
x-2x=-66-34
-x = -100
x = 100
m L DBC = x-33 = 100-33 = 67°
so, m L ABC = 2 × m L DBC =
2 × 67° = 134°

Measure of angle YXZ = 49.75 degrees
Step-by-step explanation:
Complementary angles have a sum of 90 degrees so we add them and set them equal to 90.
3x + 2 + 5x - 14 = 90
Combine like terms
8x - 12 = 90
Add 12 to both sides
8x = 102
Divide both sides by 8 to isolate x
x = 12.75
Measure of angle YXZ = 49.75 degrees

Mrs. Schellhaas spent $14.00 of the $20.00 she has on her Starbucks gift card. Which decimal represents the fraction of the $20.00 she spent
Answer:
0.7 or 70%
Step-by-step explanation:
Step 1 : Find what percent 14 is of 20. Set up an equation to solve for x.
14 = x (20)
Divide by 20 on both sides.
14 divided by 20 = 0.7
So the decimal which represents the fraction of the 20 bucks she spent is 0.7
Bonus step : If you want to find what is 0.7 in percentage form, then simply convert. 70/100 = 70 percent.
