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

Caleb is saving money to buy a bike next year. He makes $75 per week babysitting. So far he has saved $150. Write an inequality to show how many weeks he must babysit so he has at least $800 to spend on the bike, then solve the inequality.
Answer:
x>8.6
Step-by-step explanation:
We want to model an expression for the amount of money Caleb has and how many week he must work to have that amount
given data
amount at hand=$150
weekly saving=$75
let the number of weeks be x
total amount= $800
the expression for this situation is given as
y=mx+c
where y=800
m=75
c=150
substituting we have
800=75x+150
solving for x we have
800-150=75x
650=75x
x=650/75
x=8.6
then he must work for x>8.6 weeks

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

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].

3,288,336,052,853,678,818 [3.28833605285367815E+18]
≈ 3.28833605E+18
