Dom runs a pizza business. Last year he took in $88 000 and it cost him $33 000
to run. What is his percentage profit for the year? Round to the nearest cent.
Answer:
The percentage profit for the year is 62.50%
Step-by-step explanation:
Here, we want to calculate the percentage profit
That would be difference between the revenue (88,000) and the cost (33,000) divided by the revenue * 100%
We have this as;
(88,000-33,000)/88,000 * 100%
= 55,000/88,000 * 100%
= 62.50%

pls hurry will give brainliest
Answer:
Step-by-step explanation:
6(k + 2) + 1 = 13 (distribute 6 around the k+2)
6k + 12 + 1 = 13 (add 12 and 1)
6k + 13 = 13 (subtract 13 from both sides)
6k = 0 (divide by 6)
k = 0
Answer:
6( k + 2 ) + 1 = 13
6k + 12 + 1 = 13
6k + 13 = 13
6k = 0
k = 0/6
so it will 0

Please help!!! Thank you so much!!
Answer:
45 inches
Step-by-step explanation:
If the larger rectangle is 72, then you divide it by 8 because that is the ratio of the bigger rectangle. 72/8 = 9 so that means that the scale value of the shapes is 9 because they are proportional. So, you multiply 9 time 5 to get 45 which is the smaller rectangle.

7a - 4b
Step-by-step explanation:
Add the numbers ending with 'a' together, and then add the numbers ending with 'b' together.
First of all, I will put the letters beside each other.
2a + 5a + 3b - 7b
2a + 5a = 7a
3b - 7b = - 4b
Therefore, the answer is 7a - 4b.

m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.
Answer:
m<T = 20°
Step-by-step explanation:
m<R = 140°
m<S = 100°
The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:
m<S = m<U = 100°
Sum of all interior angles of a quadrilateral = 360°
Therefore:
m<T = 360° - (m<S + m<U + m<R)
m<T = 360° - (100° + 100° + 140°) (substitution)
m<T = 20°

5 donuts and 2 cups of hot Chocolate costs 24$. 2 donuts and 3 cups of hot chocolate costs 14$.How much does each donut and each cup of hot chocolate cost
Answer:cost of each donut =$4
and cost of each cup of hot chocolate =$2
Step-by-step explanation:
Step 1
Let donuts be represented as d
and cups of hot chocolate be rep as c so that
5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as
5 d+ 2 c= 24
And 2 donuts and 3 cups of hot chocolate costing 14$ will be expressed as
2d +3 c= 14
Step 2
Using elimination method,Multiply equation 1 by 3 and equation 2 by 2
15d+ 6c= 72----equation 3
4d+ 6c= 28-----equation 4
Subtracting equation 4 from equation 3 gives us
11 d=44
d= 44/11
d= 4
To find c, using equation 1
5 d+ 2 c= 24
5 x 4+ 2c=24
20+2c=24
2c=24-20
2c=4
c=4/2 =2
cost of each donut =$4
and cost of each cup of hot chocolate =$2

3n + 8 = 53
I don’t understand how to find the n
Answer:
n=15
Step-by-step explanation:
subtract 8 from both sides to get 3n=45
divide both sides by 3 to solve for n to get n=15
Answer:
n = 15
Step-by-step explanation:
3n + 8 = 53
the first step we are going to do is combine the like terms by moving the constant (8) to the right and subtracting
3n = 45
next step, we are going to isolate the n by dividing by 3 on both sides of the equation
3n divided by 3 is just n and 45 divided by 3 is 15, so we have our answer
