Step-by-step explanation:
When we rotate clockwise or counterclockwise, the two rotations should always add up to _________ degrees
Two counter-clockwise or clockwise rotations of 90° should become 180°
If you add a counter-clockwise and clockwise rotation of 90° together they will cancel out to 0°
If you add full rotations of either in any amount it will always be 0°
Answer:
Two counter-clockwise or clockwise rotations should become 180°
If you add a counter-clockwise and clockwise rotation together they will cancel out to 0°
Step-by-step explanation:
Mike hiked to a lake in 5.5 hours at an average rate of 2 1/5 miles per hour. Pedro hiked the same distance at a rate of 2 3/5 miles per hour. How long did it take for Pedro to reach the lake? Round to the hundredths place.
We first need to find the distance.
The information about Mike will provide the distance we need to answer the question about Pedro.
We will use D = rt
Mike:
(6.5)((17/5) = D
22.1 miles = D
Pedro:
D = rt
22.1 = (19/5)t
We need to find t.
22.1 ÷ 3.8 = t
5.8157894737 = t
We now round off as instructed.
5.82 = t
It took Pedro 5.82 hours to reach the lake.

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.
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
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

Step-by-step explanation:
Sandy works at a clothing store. She makes $6 per hour plus earns 10% commission on her sales. She worked 79 hours over the last two weeks and had a total of $2,822 in sales before taxes.
Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
A.
$282
B.
$474
C.
$330
D.
$756
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
x+3y=-2 and 5x-3y=26 in (x,y) form pls!!
x + 3y = -2
=> x = -2-3y ----iAlso 5x -3y = 26
=> 5 (-2-3y) -3y =26
=> -10 -15y -3y =26
=> -18y = 36
=> y = -2Putting y = -2 in equation i we get,
x= -2 -3(-2)
=> x = -2 +6
=> x = 4Thus The solution is (4, -2)Answer:
(4, -2)
Step-by-step explanation:
Please be sure to share ALL of the instructions. Here you meant "Solve the following set of simultaneous equations and present your solution in (x, y) form."
Note that the first equation features +3y and that the second features 5x - 3y = 26. Simply adding like terms results in our having eliminated the variable y:
6x = 24
Then x = 24/6 = 4
The x coordinate of the solution is 4; Substituting 4 for y in the first equation results in
4 + 3y = -2
which simplifies to 3y = -6. Thus, y = -2, and the solution is
(4, -2)

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.
The original quantity is 20 and the new quantity is 15. Adam incorrectly says the percent decrease is about 14.29%. What is the correct percent decrease? What error did Adam likely make when finding the percent decrease? The correct percent decrease is 25 25%. What error did Adam likely make? A. divided the difference of the two quantities by the sum of the two quantities. B. divided the difference of the two quantities by the product of the two quantities. C. divided the difference of the two quantities by the new quantity. D. divided the new quantity by the original quantity.
Answer: A. divided the difference of the two quantities by the sum of the two quantities.
===================================================
Explanation:
The difference of the quantities is 20-15 = 5
The sum of the quantities is 20+15 = 35
Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429
That converts to 14.29%
This is likely the path Adam took. This path is incorrect. The correct steps are shown below
---------------------
Difference = 20-15 = 5
Divide the difference over the original quantity
5/20 = 1/4 = 0.25 = 25%
We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)
----------------------
Here's another way to approach the problem
A = old value = 20
B = new value = 15
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-20)/20 ] * 100%
C = (-5/20)*100%
C = -0.25*100%
C = -25%
The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.

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.
Solve for x: -6 (1 - 5x) = 324 PLEASE SHOW ALL YOUR WORK! Thank you!
Answer:
11
Step-by-step explanation:
-6(1-5x)=324 divide both sides by -6
1-5=-54 move constant to the right-hand side and change its sign
-5x=-54-1 calculate the difference
-5x=-55 divide both sides of the equation by -5
x=11

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
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
