Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in -100.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.

Answer:
Chelsea can make 3 [tex]\frac{1}{2}[/tex] batches of icing with 7/8 pounds of butter.
Step-by-step explanation:
7/8 ÷ 1/4 (reciprocate 1/4 to replace division sign with multiplication sign)

What is the value of T in this exterior angle
Answer:
t =30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles.
t + (2t-28) = t+32
Combine like terms
3t -28 = t+32
Subtract t from each side
3t -28-t = t+32-t
2t -28 = 32
Add 28 to each side
2t-28+28 = 32+28
2t = 60
Divide by 2
2t/2 = 60/2

Find the value of x and y.
Answer:
x=25, y=19
Step-by-step explanation:
130+2x=180
x=25
54+2x+4y=180
y=19
Answer:
x = 25 , y = 19
Step-by-step explanation:
130° and 2x° are adjacent angles on a straight line and sum to 180° , so
130 + 2x = 180 ( subtract 130 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
--------------------------------------------------------------
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle , then
54 + 4y = 130 ( subtract 54 from both sides )
4y = 76 ( divide both sides by 4 )
y = 19
You and 3 friends are going to the country fair. You have a coupon that will save your group $20. If the total bill to get into the fair was $100, how much does one regular price ticket to the fair cost?
Answer:
30$
Step-by-step explanation:
lets assume you didn't have a coupon then the total bill would have been 120$
so for 4 friends including u the bill would have been 120$
: 4 friends = 120 $
for : 1 friend = x$
cross multiply
4x = 120 × 1
4x =120
divide both sides by the coefficient of x
x =120 \ 4
x = 30$
therefore: 1 friend = 30$

The price of an item yesterday was $130. Today, the price rose to $299. Find the percentage increase.
Answer:
130%
Step-by-step explanation:
Use the formula for percent change: difference = % * original price
To find the difference, you have to do 299 - 130, which is 169.
The original price is $130 because this is the price before it rose to $299.
Now, you have the equation 169 = % * 130.
We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.
130%
Step-by-step explanation:
Yesterday = $130.
Today = $299 .
((final price - initial price)/(initial price)) × 100%
= (($299 - $130)/$130) × 100%
= ($169/$130) × 100%
= $1,3 × 100%
= 1,3 × 100%
= 130%

What are the coordinates of F after a reflection over the line y=1? Give your answer in the format (#,#)
Answer:
So for the coorfinates of F, you have to see how far it is from y=1. The F is 2 points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)
the sum of person x and person y is 2640. if person x's income is 20% more than person y, find person x's income.
please answer fast fast plssssss as soon as possible
Answer:
I do not understand she question do you mean the sum of their income is 2640
if so, then the answer is 440 to be x income
Step-by-step explanation:
x income = 20% or 1/5 of y income
y income = 5 of x income
we know that the sum of their income = 2640
which means that
x + y = 2640 =
1/5y + y = 2640
6y/5 = 2640
cross multiply to give us
6y = 5(2640)
6y = 13200
divide through by 6 to give us,
6y/6 = 13200/6
y = 2200
since we know that x income is 20% y income,
therefore, x income =
20/100 * 2200
= 440
therefore,
x income = 440
y income = 2200
Answer:
1440Step-by-step explanation:
The equations to reflect the given:
x + y = 2640x = y + 20% ⇒ x = 1.2ySubstitute the value of x into first equation and solve for y:
1.2y + y = 26402.2y = 2640y = 2640/2.2y = 1200Find x:
x = 2640 - 1200 = 1440four times a number increased by 5 is equal to45

How do you find percentages?
Answer:
obtained number divided by total number multiply by 100%.
· Definition of Percentages
Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent. The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.
1. Determine the initial format of the number to be converted to a percentage
The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.
2. Carry out a mathematical process on the number to be converted to a percentage
If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.
3. Multiply the result of the mathematical process by 100
If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.
However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.
Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.

Answers: The page numbers are 11 and 12
==========================================================
Explanation:
Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.
Let,
x = first page, some positive whole numberx+1 = second page, follows immediately after page xAdding those two said pages will lead to 23
first + second = 23
(x) + (x+1) = 23
2x+1 = 23
2x = 23-1
2x = 22
x = 22/2
x = 11 is the first page
x+1 = 11+1 = 12 is the second page
Check: 11+12 = 23 which confirms the answers.
