Answer:
C. x = 8
Step-by-step explanation:
We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.
Let's multiply 6 x 6 x 6.
36 x 6 = 216.
Let's multiply 8 x 8 x 8.
64 x 8 = 512
The answer would be C. x = 8.
I hope that this helps! :)
Answer:
8
Step-by-step explanation:
x³ = 512
x³ = 8³
Cube root on both sides,
x = 8

The measure of the other remote interior angle is 60°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Let the measure of the other interior angle = M
The exterior angle is equal to the sum of the interior angles in a given triangle.
An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.
This means,
M + 20 = 80
Solve for M.
M + 20 = 80
Subtract 20 on both sides.
M = 80 - 20
M = 60
Thus,
The measure of the other remote interior angle is 60°.

What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.

Answers
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.

What are two ways to start solving the equation 4(c - 3)=8? Choose BOTH ways
1. Add 3 to both sides to get 4c = 11
2. Divide both sides by 4 to get c - 3 = 2
3. Use the distributive property to get 4c - 3 = 8
4. Use the distributive property to get 4c - 3 = 8
5. Subtract 4 from both sides to get c - 3 = 4
Answers
Answer
2, i can't find any other solution
Step-by-step explanation:
you divided both sides by 4 you get x - 3 = 2/2 plus 3 = 5 = x
To solve an equation 4(c - 3) = 8 the correct ways are
1. Use the distributive property to get 4c - 12 = 8
2. 2. Divide both sides by 4 to get c - 3 = 2
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
The two ways to start solving the equation 4(c - 3) = 8 are:
Use the distributive property to get 4c - 12 = 8, then add 12 to both sides to get 4c = 20, and finally divide both sides by 4 to get c = 5.
This method uses the distributive property to simplify the left-hand side of the equation before solving for c.
Divide both sides by 4, and we get,
4(c - 3)/4 = 8/4
c - 3 = 2
c = 5.
Therefore, the two ways are given above.

O 22x32
0 22x33
O 2x32
Answers
Answer:
2³×3²
Step-by-step explanation;
TO FIND A PRIME FACTORIZATION OF A NUMBER YOU FIRST NEED TO KNOW PRIME NUMBERS ARE;Prime Numbers are numbers which which have only two factors the number itself and one
Examples of Prime Numbers are;
2,3,5,7,11,13,17,19,23,29,etc
To Find The Prime Factorization Of The Number 72 you'll need to follow this;
72=2×36(we have the number 36 because when it's multiplied by 2 the product is 72 and 36 is not a prime number so it has to be broken down but since 2 is a prime number you leave it as it is)
72=2×2×18(we have 2×18 because because it's give us the product of 36 when multiplied so now that we have a second prime number(2) we will have to continue to break down the number 18)
72=2×2×2×9( We again have two another 2 and 9 here because when multiplied by each other its product is 18 so as we can see 9 is not a prime number so we have to break it down but the 2 is a prime number so we let it be)
72=2×2×2×3×3( As we can see here, 3 and 3 is a prime number so nothing happens to it so we have broken the non-prime numbers down so now we have all the numbers as Prime Numbers)
So; 72=2×2×2×3×3
So we are going to count the twos and threes so as you can see we have three twos and we have two threes. Which makes our final answer;
2³×3²
So The Prime Factorization of 72 is; 2³×3²

Step-by-step explanation:
to find slope use two points given
(x1, y1) = (6, 0)
(x2, y2) = (0, 360)

Kevin bought twelve 8-ounce bottles of water. How many milliliters of water did Kevin buy? (Note: 1 ounce ≈ 30 ml) Thank you for any help I may get! <3
Answers
Given:
Kevin bought twelve 8-ounce bottles of water.
1 ounce ≈ 30 ml
To find:
The quantity of water in milliliters
Solution:
We have,
1 ounce ≈ 30 ml
8 ounce ≈ 8×30 ml
8 ounce ≈ 240 ml
It means, one 8 ounce bottle can hold about 240 milliliters of water.
Total number of bottles = 12
So, the quantity of water Kevin buy in milliliters is
[tex]12\times 240=2880[/tex]
Therefore, Kevin buys 2880 milliliters of water in twelve 8-ounce bottles.

In 1995 the town of Springdale had a population of 2,378. Over the next 20 years the town's population decreased by 12.5%. What was the population of the town in 2015?
Answers
Answer: 165
Step-by-step explanation:
Exponential equation for decay :[tex]A= P(1-r)^t[/tex] , where A is the value after t year, P = initial value.
As per given ,
P= 2378
t= 20 years
r = 12.5% = 0.125
Now ,
[tex]A=2378(1-0.125)^{20}\\\\=2378(0.875)^{20}\\\\= 2378(0.0692087587)\\\\=164.57842\approx 165[/tex]
Hence, the population of the town in 2015 = 165

In △ACD, if AC≅AD, m∠A = 3x − 4, m∠C = 5x + 1, and m∠D = 7x − 27, find x and the measure of each angle.
Answers
Answer:
x = 14
m∠A = 38°
m∠C = 71°
m∠D = 71°
Step-by-step explanation:
By the property of a triangle,
"Sum of interior angles of a triangle is 180°"
m∠A + m∠C + m∠D = 180°
By substituting the values of the angles given in the question,
(3x - 4)° + (5x + 1)° + (7x - 27)° = 180°
(3x + 5x + 7x) + (-4 + 1 - 27) = 180
15x - 30 = 180
15x = 210
x = 14
Therefore, m∠A = 3x - 4
= 3(14) - 4
= 38°
m∠C = 5x + 1
= 5(14) + 1
= 71°
m∠D = 7x - 27
= 7(14) - 27
= 98 - 27
= 71°
