Describe how you solved the following problem:I have a jar filled with $100 worth of quarters, nickels, and dimes.

I have the same amount of each type of coin. How many total coins do I have in my jar?

Answers

Answer 1

Answer: first you make sure you have all your variables using same measurement - cents (since it is the smallest)

$100 = 100*100 cents = 100,000 cents
1 quarter = 25 cents
1 nickel = 5 cent
1 dime = 10 cents

the test of your problem said that:
you have $100 in i don't know how many coins of quarters, nickels and dimes
100,000 = X * (25+5+10)

we have to find X:

100,000= X *(25+5+10)
100,000= X *40
X= 100,000/40
X = 2,500 coins

Write 5.2 as the quotient of two integers A...11/3
B...21/5
C...26/5
D...51/10

Answers

Answer:

C) $(26)/(5) = 5.2$ .

Step-by-step explanation:

Given : Number 5.2

To find : write 5.2 as the quotient of two integers.

Solution : We have given Number 5.2

For $(11)/(3) = 3.666$ .

For $(21)/(5) = 4.2$ .

For $(26)/(5) = 5.2$ .

For $(51)/(10) = 5.1$ .

So, 5.2 is quotient of 26 and 5 integers.

Therefore, C) $(26)/(5) = 5.2$ .

it would be C because what i did A. 11 divided by 3=3.666666666666666666
B.21 divided by 5=4.2 C. 26 divided by 5= 5.2 D. 51 divided by 10=5.1 we want 5.2 and C = 5.2

What percent of 100 is 30?
a. 30%
b. 333%
c. 3.33%
d. 0.3%

Answers

If you would like to know what percent of 100 is 30, you can calculate this using the following steps:

x% of 100 is 30
x% * 100 = 30
x/100 * 100 = 30
x = 30%

The correct result would be a. 30%.

We set up a proportion: 30/100= ?/100

Because we have the same denominator, the two numerators must be equivalent.

Therefore, ?= 30.

The correct answer is a. 30%
