Answer:

oki! Mizuki here to help! 12 will be your answer!

Step-by-step explanation:

Soo... The ratio of blue to green is 4:3 right?

and there are 21 balloons!

4 + 3 is 7! So we divide 21 by 7 and get 3!

Then we multiply 3 by the number of blue balloons(aka 4) and get 12!

A quiz has five true or false questions. How many possible ways could the five questions be answered?
dybincka [34]

Answer:

The total number of ways to answer = 32

Step-by-step explanation:

A quiz has five questions that can be answered as true or false.

Each question can be answered in two ways.

Lets take each question one by one.

The first question can be answered as true or false that is two ways.

Similarly each question answered in 2 ways.

To get the total number of ways, we have to multiply the number of ways for each question.

Hence the total number of questions = 2\times 2\times 2\times 2\times 2

                                     = 32

The bill is $100.99. You want to leave a 20% tip. How much should the tip be?
Arisa [49]

Answer:

$20.20

Step-by-step explanation:

First Convert 20% into a decimal, by dividing it by 100

Percent = out of 100

20/100 = 0.2

Now, multiply the decimal (0.2) with the bill amount ($100.99):

0.2*100.99

$20.198 <== *remember, we are using money, so we round to the nearest cent (dime)

$20.20 <== how much tip you want to leave

How much you pay altogether:

(Bill + tip)

100.99 + 20.20

$121.19

Hope this helps!
