C: Naomi is faster because she runs a full mile in 8 minutes while Amal runs a mile in 12 minutes.
Step-by-step explanation:
Since he can run 1/8 miles in 1.5 minutes, times 1.5 by 8 to get a mile. Then times that by 3 to get 3 miles. Now calculate how long it takes Naomi to run a mile, 2 times 4 which is 8 minutes. We know Amal runs a mile in 12 minutes, so Naomi is faster.

angle x=40
Step-by-step explanation:
Angle CD on the bottom is a 180 angle. If you subtract it by 110 it's 70. The two bottom angles are equal so it also equals 70, add them and you get 140. Subtract 180 by 140 and it means x=40!
The sale price of an item is $160 after a 20% discount. What was the original price of the item?
Answers
Answer:
200 sorry read that wrong
Step-by-step explanation:
Answer:
The original price of the item is $200.
Step-by-step explanation:
Let the original price be 'x'.
The sale price of an item is $160 after a 20% discount.
i.e. original price - 20% of original price = $160
x-20/100x=160
x-0.2x=160
0.8x=160
x=160/0.8
x=200
Therefore, the original price of the item is $200.

Does the number 30 have a decimal expansion?
Yes, because every number has a decimal expansion.
No, because it is rational.
Yes, because it is irrational.
No, because not every number has a decimal expansion.
Answers
Yes, because every number has a decimal expansion. Option A is correct.
GIven that,
To justify whether the number 30 has a decimal expansion.
Decimal value is defined as showing the place value of the digits in a decimal number. If any proportion of the digit is lower than 1 it would be represented after the dot right to the absolute value.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given number = 30
Decimal expansion, 30 = 30.000
So, it's true that the number 30 has a decimal expansion because every number has a decimal expansion.
Thus, Yes, every number has a decimal expansion so as is 30. Option A is correct.

Two sides of a triangle have lengths of 7 and 15. Which inequality represents the possible lengths for the third side?
A) 8 < x < 7
B) 7 < x <15
C) 8 < x < 15
D) 8 < x <22
Answers
Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
[tex]7+15>x[/tex]
However, 15 can also be our largest side. So:
[tex]7+x>15[/tex]
Let's solve for x for both inequalities.
First inequality:
[tex]7+15>x[/tex]
Add:
[tex]22>x[/tex]
Flip:
[tex]x<22[/tex]
Second inequality:
[tex]7+x>15[/tex]
Subtract 7 from both sides:
[tex]x>8[/tex]
So, we have the compound inequality:
[tex]x>8\text{ and } x<22[/tex]
Combine:
[tex]8<x<22[/tex]
Our answer is D
And we're done!

plz tell me what y + 4 = ½ (x – 4) is in standard form of a linear equation this is my 3rd question about it i need it plz
Answers
Answer:
1/2x - y = 6
Step-by-step explanation:
First, distribute 1/2 to the parentheses:
y + 4 = ½ (x – 4)
y + 4 = 1/2x - 2
Then, subtract y from both sides:
4 = 1/2x - y - 2
Add 2 to both sides:
6 = 1/2x - y
Reorder the equation:
1/2x - y = 6 is the standard form of the equation

Answers
Answer:
1) -15/32
2) 2/15
3) -203.5
4) -3/2 = -1.5
5) 10/3 = 3 1/3
Step-by-step explanation:
For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.
For 2, you multiply again, but because there are 2 negative signs, it becomes positive.
For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.
For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.
For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.
1. -15/32
-3/4 TIMES 5/8. So what you are going to do is multiply the bottom number by the top number and remember that a negative times positive equals negative. -3 times 5 equals -15 so that's the top number. Then, do the bottom number and it's 8 times 4, which is 32.
2. 2/15
So you do the same stuff for the last problem but now for this one so -1 times -2 is positive 2 so that's going to be the top number. Then 5 times 3 is 15.
3. -203.5
(-81.4)/0.4. So what you can do is do long division and get -203.5.
4. -1/5
(-2 1/4)/11/2. So what we can do is put the first fraction into improper fractions. So that would be -9/4 DIVIDED by 11/2. So then you're going to multiply 11/2 by 2 and get 22/4. Now we have -9/4 divided by 22/4.
5. 3 1/3
Switch them to improper fractions. -4/3 times -5/2. This will definitely be a positive because of the fact that it's a negative times a negative. This would equal 20/6 which can be simplified to 3 and 1/3.

c = 3
Step-by-step explanation:
You are solving for the variable, c. Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 1 from both sides of the equation:
3c + 1 = 10
3c + 1 (-1) = 10 (-1)
3c = 10 - 1
3c = 9
Next, divide 3 from both sides of the equation:
(3c)/3 = (9)/3
c = 9/3
c = 3
c = 3 is your answer.

Answers
Answer:
$778.60
Step-by-step explanation:
Sandy worked 80 hours over the last two weeks. She makes $6 per hour, so she earned
$6 x 80 =480
Sandy had a total of $2,986 in sales before taxes. Sandy earns 10% commission on her sales, so
$2,986 x 0.1 = 298.60
is Sandy's earning on sales.
In total, Sandy earned
$480 + $298.60 = $778.60
