Answer:
64
Step-by-step explanation:
The exponent of a number says how many times to use the number in a multiplication.
8 to the Power 2
In 82 the "2" says to use 8 twice in a multiplication,
so 82 = 8 × 8 = 64
In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"

if akayla painted 1/3 of a wall in 20 minutes how long will it take her to paint 4 walls
Answer:
240 minute or 4 hours
Step-by-step explanation:
We can use a ratio to solve
1/3 wall 4 walls
------------- = ----------------
20 minutes x minutes
Using cross products
1/3 x = 20 *4
1/3 x = 80
Multiple each side by 3
1/3 x* 3 = 80*3
x = 240 minutes
Divide each side by 60 to change to hours
x = 240/60
x = 4 hours
JJill begins the summer with $500 in her savings account. Each week, she withdraws $20. Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week. At what week will both Jill and Sam have the same amount in their account.
Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
Review: Angle Bisectors
A
Directions: Label the diagram with the
proper congruence markings and known
measurements.
Answer:
m∠AOC = 15°m∠BOC = 15°Step-by-step explanation:
Given the angle ∠AOB
It is stated that CO is the angle bisector of ∠AOB.
Given that ∠AOB = 30°
As we know that the angle bisector bisects the angle into two equal angles.
Thus, the angle bisector CO bisects the angle ∠AOB into two equal angles, which are:
m∠AOCm∠BOCas
∠AOB = 30°
Thus, the two formed angles i.e m∠AOC and m∠BOC by the angle bisector would be half of the angle bisector as the angle bisector bisects the angle ∠AOB into two equal angles.
Therefore,
m∠AOC = 15°m∠BOC = 15°when the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. if one integer is 45, what is the smallest possible value of the other integer?
The smallest value of the other number will be 3 ×5× 11 =165
In the given statement is :
When the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. If one integer is 45.
To find what is the smallest possible value of the other integer
Now, According to the question
One of the numbers 3 ×3× 5 = 45
The lowest common multiple has to be a multiple of 45 i.e.,
3 ×3× 5 something when LCM is divided by the greatest common divisor
then the answer is 33 = 3 x 11 .
So the other number will have to be a multiple of 11
3 ×3× 5× 11 × ?/ some factor of 4 = 33
(3 ×5) ×3× 11 × 1 /3 × 5 = 33
So if the greatest common divisor is 3× 5 the given number is 3 ×3× 5
Hence, The smallest value of the other number will be 3 ×5× 11 =165

If ABCD is a rectangle, BD = 2x + 5 and AC = 7x - 40. Find the value of BE.
Answer:
AC = 23
BD = 23
Step-by-step explanation:
ABCD is a rectangle,
AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
7x - 40 = 2x + 5
7x - 2x = 5 + 40
5x = 45
x = 45/5
x = 9
BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23
AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23

8. Two streets intersect at a traffic light, forming vertical angles. If the
measure of one of the angles formed by the intersecting streets is 78°,
what are the measures of the other three angles? Draw and label a
picture of the scenario. Show your work for how you found the missing
angles. (3 points)
The measures of the angles in the intersection are 78 degrees, 78 degrees, 102 degrees and 102 degrees
How to determine the measure of the three variables?The measure of one of the angles is given as 78 degrees
Represent this angle with x
So, we have
x = 78
Vertical angles are congruent angles
This means that
Vertical angle = x = 78
The other angles adjacent these angles are also congruent
And the measure of these angles is calculated using
y + x = 180
Substitute the known values in the above equation
So, we have
y + 78 = 180
Subtract 78 from both sides of the equation
So, we have
y + 78 - 78 = 180 - 78
Evaluate the like terms in the above equation
So, we have
y = 102
This means that the measure of the other angles is 102 degrees
Hence, the measures of the angles in the intersection are 78 degrees, 78 degrees, 102 degrees and 102 degrees

Tyrone had $17,000 to invest. He invested part of that amount at 2.5% annual interest for one year and the other part at 6.5% annual interest for one year. The amount of interest earned for both investments was $550. Let x represent the amount of money invested in the first account and y represent the amount of money invested in the second account. Which system of equations best represents the situation?
Answer:
The system of equations best represents the situation
x + y = 17,000.... Equation 1
0.025x + 0.065y = 550... Equation 2
Step-by-step explanation:
Let
x represent the amount of money invested in the first account and
y represent the amount of money invested in the second account.
We are told that:
Tyrone had $17,000 to invest.
Hence,
x + y = $17,000
x + y = 17,000..... Equation 1
We also known that:
He invested part of that amount at 2.5% annual interest for one year and the other part at 6.5% annual interest for one year. The amount of interest earned for both investments was $550
The formula for Interest =
Principal(Amount invested) × Rate × Time.
Hence:
25% × x + 6.5% × y = 550
0.025x + 0.065y = 550... Equation 2
The system of equations best represents the situation
x + y = 17,000.... Equation 1
0.025x + 0.065y = 550... Equation 2
9. If two complementary angles are in the
ratio 3:7, find the supplement of the
bigger angle.
Answer:
idk
Step-by-step explanation:
Complementary angles are pair angles with the sum of 90 degrees. We have Two complementary angles are in the ratio 3:7:
α = 3k
β = 7k
Then:
3k + 7k = 90°
10k = 90
k = 90/10
k = 9
The bigger angle is:
β = 7(9) = 63°
Two Angles are Supplementary when they add up to 180 degrees. Then the supplementary angle for β is:
x = 180 - 63°
x = 117° → ANSWERSolve for v.
