(a)
127.5
is what percent of
51
?

Answers

Answer 1
Answer: To solve this, you need to divide 127.5 by 51:
127.5/51 = 2.5
To find the percent, multiply 2.5 by 100:
2.5 x 100% = 250%
So 127.5 is 250% of 51

Answer:

1a. y=550(8) + 25

1a. the yer of this problem is 25 because it is a real number. it represents your Y-intercept because they are getting paid $550 an hour and getting paid an additional $25 for doing the job. The slope of this problem would be $550 because that is how much they are getting paid an hour.

2. What you would need to do is take 500/5 and 500/56 and that would give you how ever many bags you can buy per lawn sediment. (you really don't need to write an equation for the next part even though it says you need one)

2.y=500/5 and y=500/56

When you turned 8, a family member put $470 in a savings account to help save for college or another big life goal. If your savings account continuously earns 2.1% interest per year, how much will you have in your savings account when you turn 18? (Show your work)

Answers

The answer is $578.57.

To answer this, we will use the future value of lump sum deposit (refer to the attached picture). Substitute the following given to the formula.
PV = 470
r = 2.1%
t = 10 years

FV = 470 (1 + 0.021)^10
FV = 470 (1.021)^10
FV = 470 (1.2309...)
FV = 578.57

Your savings account will contain $578.57 when you turn 18.

Of the following factors of 28, put a check beside each prime factor

Answers

Answer:

The prime factors of 28 are 2 and 7.

Step-by-step explanation:

Factors are numbers that are multiplied together to produce another number. example factors of 36 = 1, 2, 3, 4, 6, 9, 12, 36.

Prime numbers are numbers greater than 1 whose only factors are 1 and itself. example 2, 3, 5, 7, etc.

We have to find the prime factors of 28.

First we find the factors of 28 and then we pick up the prime factors.

Factors of 28 are 1, 2, 4, 7, 14, 28

Out of above factors only 2 and 7 are prime numbers

Thus, the prime factors of 28 are 2 and 7.
The factors of 28 are 1, 2, 4, 7, 14, 28.
The prime ones are 2 and 7.

It says the scale factor is 1:25000, so for every one part there is actually 25000. So for every centimeter, there is actually 25000 cm. See that we multiplied by 25000. 
So for 6.8cm, multiply by 25000 to get 170000cm. 
The real distance represented is 170000cm.

19) Just work out one step at a time using order of operations. 
Do parentheses first. 7^2 = 49, and 3^3 is 3*3*3 which is 27. 
Now you have [8(49 - 27) ]/ sqrt121. 

Finish simplifying the parentheses. 49 - 27 is 22.
[8(22)] / sqrt121.

Now multiply 8 times 22, which is 176.
176 / sqrt 121 

The square root of 121 is 11.

176/11.
= 16
#18).

-- The map has a scale factor of 1:25,000.

-- Any distance on the paper map represents
25,000 times that distance in the real world.

-- If you measure 6.8 cm on the paper map,
that represents a real distance of    (25,000 times 6.8 cm).


#19).  Relax, breathe, and take it one step at a time:

=>  7² = 49
=>  3³ = 27
=> (7² - 3³) = (49 - 27) = 22
=>  8 times that is  176 .

√121  =  11 .
