Answer:
around 40%
Step-by-step explanation:
This is a proportion question.
882 x
____ = ____
1,460 100
First, do 882 x 100 and get 88,200.
Then divide 88,200 by 1,460 to get around 60%.
Then 100-60= 40%.
Might be wrong but I'm pretty sure this is the answering method.
Answer:
70%
Step-by-step explanation:
Well, you have 3 hours to work with, which is 180 minutes. You subtract 30 minutes from warm up, then subtract another 24 minutes for group work time, and you're left with 126 minutes. Now, to figure out the percent, you take 126 divided by the total time (3 hours or 180 minutes)
126 / 180 is 0.70, which as a percent is 70%.
Okay, so first, we need to find the discounted rate of the TV:
(1 - 0.2)849 = 0.8(849) = <u>$679.20</u>
Now that we know this, we solve for the price with sales tax:
1.06(679.20) = $719.952 (this can be rounded to 719.95)
The total cost of the TV is $719.95
Answer:
a=12
Step-by-step explanation:
7a+18=102
first, subtract 18 FROM BOTH SIDES!
then you get 7a=84.
next, divide BOTH SIDES by 7
and you get a =12 :)
T us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3
