If you are being paid $55 for a days work which is an 8 hour shift how much would you get paid if you only worked 6 hours?
Answer:
You would get paid $41.25 if you only worked 6 hours.
Step-by-step explanation:
In order to find the answer, first you have to find the amount you are paid per hour by dividing the amount paid per day by 8 hours:
$55/8=$6.875
Then, you have to multiply the amount per hour for 6 to determine the amount you would get paid if you only worked 6 hours:
$6.875*6=$41.25
According to this, the answer is that you would get paid $41.25 if you only worked 6 hours.

A triangular pane of glass has a height of 42 inches and an area of 546 square inches. What is the length of the base of the pane?
Answer:
Base = 26 in
Step-by-step explanation:
Recall the formula for the area of a triangle as:
Area = (Base x Height) / 2
In our case, this formula converts into:
546 in^2 = Base x 42 in /2
multiply both sides by 2 to get rid of fractions:
1092 in^2 = Base x 42 in
divide both sides by "42 in" to isolate the Base completely
1092 in^2 / 42 in = Base
Therefore Base = 26 in
If the area of a square sandbox is 64 square meters, which is closest to the length of the diagonal of the sandbox? F 8 m G 9 m H 10 m J 11 m
Answer:
Step-by-step explanation:
A=s^2=64
s=8m
d^2=x^2+y^2, since it is a square x=y=8 then
d^2=2x^2
d^2=2(8^2)
d^2=128
d=11.3
So diagonal is approximately 11m

Answer: D.) 2
Step-by-step explanation:
In a rhombus, all sides are congruent; they have the same lengths (like a square). This means that if this parallelogram was a rhombus, 14 - x and 2x + 8 will have to be equal.
14 - x = 2x + 8
Subtract 2x from both sides
14 - 3x = 8
Subtract 14 from both sides
-3x = -6
Divide both sides by -3
x = 2

You have 5 3/4 cups of sunflower seeds and 1 1/4 cups of peanuts for birdseed. You use 2/3 of the total mixture each week. How many weeks your birdseed mixture last
Answer:
Step-by-step explanation:
The bird food lasts 1½ weeks.
Your birdseed mixture last till 10 and a half weeks.
What is an improper fraction?A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.
Given:
You have 5[tex]\frac{3}{4}[/tex] cups of sunflower seeds and 1[tex]\frac{1}{4}[/tex] cups of peanuts for birdseed.
The total mixture,
= 5[tex]\frac{3}{4}[/tex] + 1[tex]\frac{1}{4}[/tex]
= 23/4 + 5/4
= 28/4
= 7 cups.
You use 2/3 of the total mixture each week.
That means,
the number of weeks,
= 7 x 3/2
= 21/2
= 10.5 weeks.
Therefore, the mixture will last till 10 and a half weeks.
