so first of all we need to get rid of the time that isn't spent in class, because the question is asking about the time spent in class. so we would add 30+42 giving us 72 minutes, or 1 hour and 12 minutes. Now we can subtract 1 hour and 12 minutes from 7 hours to find the total time spent in class. Which would give us 5 hours and 48 minutes. (reminder; 60 minutes in 1 hour)
now that we have the total time spent in class, all that is left is division. The equation would be easier to solve when the hours are converted into minutes. 5 hours and 48 minutes equal, 348 minutes. Now we would divide 348 by 6 as there are 6 classes that take 348 minutes in all, and we wanna find how long 1 class takes. 348 divided by 6 would then give us 58. so each class takes 58 minutes.
(srry if the answer is wrong)

How would I be able to simplify 12/3? Please explain step by step
Answer:
4/1
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 12 and 3 is 3.
12 ÷ 33 ÷ 3.
Reduced fraction: 41. Therefore, 12/3 simplified to lowest terms is 4/1.
Answer:
i think you divide 12/3 and you get the answer of 4

If you wanted to find the difference of 6/25 - 4/5, what common denominator should you choose? Why?
Answer:
Choose 1/25 as the common denominator
Step-by-step explanation:
1/25 is the lowest number that both existing denominators can be factored into.
6/25 would remain the same.... 6/25
4/5 would become 20/25..... multiply the top and bottom by 5
So 6/25 - 20/25 = - 14/25

A married man filing separably with a taxable income of $130,000. Compute the tax owned (look at chart)
--PLEASE show work
First, find the tax rate for a person whose taxable income is $130,000. By looking at the table, you can see the tax rate is 33%. To find the total tax, multiply 33% by $130,000.
[tex]0.33 \times 130000 = 42900[/tex]
Thus, the tax this person has to pay is $42,900.

A triangle with an area of 370 square inches
has a height that is 6 less than 8 times its
base. Find the base and height, in inches, of
the triangle.
Base=
Height=
Answer:
Step-by-step explanation:
Area of triangle = 1/2 (base × height)
Given, area of a triangle is 192 sq ins. and its height is 8 ins less than its base.
Then, let base = b, height = b-8
Hence, 1/2 (b)*(b-8) = 192
Above equation; “times 2”,
(b)*(b-8) = 384
b^2 - 8b - 384 = 0
(b+16)(b-24)=0

These angles are called alternate interior angles and because you are given that they are = then there are two parallel lines. The converse of the theorem stated. If alternate interior angles are cut by a transverse and two lines and the alternate interior angles are equal, then you have a pair of parallel lines.

16. A craft shop sold 150 pillows. Small pillows were $6.50 each and large pillows were $9.00 each. If the total amount collected from the sale of these items was $1180.00, what is the total number of each size pillow that was
sold?
Answer:
82 large pillows, 68 small pillows
Step-by-step explanation:
Suppose all pillows sold were small pillows:
150×$6.50=$975
$1180-$975=$205
$9-$6.50=$2.50
$205÷$2.50=82 (no of large pillows sold)
No. of small pillows sold
=150-82
=68
