Answer: 88
Step-by-step explanation:
First use the distributive property.
4(15 + 7) can turn into 4(15) + 4(7)
Then we simplify until we get the answer.
4(15) = 60
4(7) = 28
Then it is...
60 + 28
Just add them together...
60 + 28 = 88
So the answer is 88. I hope this helps, and I hope it's not wrong, but I do not think it is.

Complete Question
An arts academy requires there to be 3 teachers for every 57 students and 4 tutors for every 44 students. How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 121 students?
Answer:
a)19 students per teacher
b)11 students per tutor
c)11 tutors if they have 121 students
Step-by-step explanation:
An arts academy requires there to be 3 teachers for every 57 students and 4 tutors for every 44 students.
a) How many students does the academy have per teacher?
3 teachers for every 57 students
3 teachers = 57 students
1 teacher = x
Cross Multiply
3x = 1 × 57 students
x = 57 students/3
x = 19 students
Hence, we have 19 students per teacher
b) How many students Per tutor?
4 tutors for every 44 students.
4 tutors = 44 students
1 tutor = x students
Cross Multiply
4x = 44 × 1
x = 44/4
x = 11 students.
This means that we have 11 students per tutor
c) How many tutors does the academy need if it has 121 students?
4 tutors for every 44 students.
44 students = 4 tutors
121 students = x
Cross Multiply
x = 121 × 4/44
x = 11 tutors
Hence, the school would need 11 tutors if they have 121 students

What is Becca's speed in miles per hour?
Answer: 3/2
Did this on I ready
The speed of Becca for the given data is 3/2 miles per hour.
What is speed?The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction The term "velocity" refers to the combination of direction and speed.
Given the hiking distance of Becca = 9/10 miles
time taken = 3/5 hours
to find the speed,
speed = distance/time
speed = (9/10) ÷ (3/5)
speed = 9/10 x 5/3
speed = 3/2 miles per hour
Hence the speed of Becca is 3/2 miles per hour.

Rewrite 3^-7 using a positive exponent.
Answer:
1/3^7
Step-by-step explanation:
Negative exponents go to the denominator
The positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].
The given exponent is [tex]3^{-7}[/tex].
What is an exponent?The exponent of a number shows how many times the number is multiplied by itself.
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number.
Now, [tex]3^{-7}=\frac{1}{3^7}[/tex] (∵[tex]a^{-n}=\frac{1}{a^n}[/tex])
Therefore, the positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].

Step-by-step explanation:
It takes Kelsey 5 hours to make 12 pendants. If she works 8 hours per day for 3 days before the craft fair, can she make enough additional pendants to sell so that she can make a profit of at least $50?
Answer:
From a search on google, the first part of this problem is:
Kelsey has to pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50. To make a profit, she must make more money than she spends. Kelsey has already made 10 pendants.
We know that:
I takes Kelsey 5 hours to make 12 pendants.
She works 8 hours per day, for 3 days.
then she works a total of 24 hours.
We want to find the number of pendants that she can make in that time, first, how many groups of 5 hours there are in 24 hours?
(24h/5h)
And in each one of those groups, she can make 12 pendants, this means that the total number of pendants that she will make is:
(24h/5h)*12 = 57.6 pendants.
And we should round it down to 57 pendants because 0.6 of a pendant does not make sense.
Now let's calculate the profit.
Remember that the profit is the difference between the revenue and the costs.
The costs will be:
C(x) = $200 + $7.80*x
Where x is the number of pendants that she made.
In these 3 days, she made 57 pendants, plus 10 that she did before, she has 67 pendants, then x = 67.
C(67) = $200 + $7.80*67 = $722.60
And the revenue will be:
R(x) = $13.50*x
for the 67 pendants:
R(67) = $13.50*67 = $904.50
Then the profit will be:
P = R - C = $904.50 - $722.60 = $181.90
So yes, her profit will be a lot more than the minimal of $50 asked in the question.

He has $50.00 to spend on sandwiches that cost $2.50 per person, $25.00 to spend on drinks that cost $1.50 per person, and $25.00 to spend on gift bags that cost $3.00 per person. Which expression could be used to show the amount of money he will have left over if x people attend the party? 50 + 7 x 100 minus 7 x 2.50 x + 1.50 x + 3.00 x 100 minus (2.50 x minus 1.50 x minus 3.00 x)

given data
amount for sandwiches=$50
amount for drinks is $25
amount for gift bags=$25
total amount=$100
the number of persons be x
cost of sandwiches= 2.5x
cost of drinks= 1.5x

After eight years, the value of Edward's home increased by $24,386.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Edward purchased his home for $89,000.
For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year.
And, For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year.
Now,
After three years, the value of Edward's home increased by,
⇒ 3 × (4.8% of $89,000)
⇒ 3 × (4.8/100 × 89,000)
⇒ 3 × 4,272
⇒ $12,816
And, After five years, the value of Edward's home increased by,
⇒ 5 × (2.6% of $89,000)
⇒ 5 × (2.6/100 × 89,000)
⇒ 5 × 2,314
⇒ $11,570
Thus, After eight years, the value of Edward's home increased by,
⇒ $12,816 + $11,570
⇒ $24,386
