Answers

Answer 1
Answer:

Answer:

0.70*300=x

Step-by-step explanation:

Let the number of mid sized cars in the parking garage be = x

Total vehicles parked in the garage = 300

And out of 300, 70% are mid sized.

So, 0.70*300=x

Therefore, x = 210

So, number of mid sized cars in the garage are 210.

210 midsize cars are in the parking garage

A number cube is rolled. What is the probability of rolling 2, 3, or 5?PLEASE HELP!!!!!

Answers

Since there are six sides of a cube, or a die, the probability of rolling a 2 is 1/6. In the same way, the probability of getting a 3 is 1/6 and getting a 5 is also 1/6. Hence, the probability of rolling 2, 3 or 5 is the sum of all the probabilities each number can be rolled. That is P = 1/6 + 1/6 + 1/6 which is 3/6 or 50%. There is a 50% chance that the number rolled is 2, 3, or 5. 
The probability of rolling any one of these numbers is 1/6, which converted in to percentage is 16.6%. The probability of rolling any two of these numbers is 2/6 which converted in to percentage is 33.3%. The probability of rolling all 3 of these numbers is 3/6, which converted in to a percentage is 50%. Hope it helps:).

What s the total cost of a $12.50 item plus 7% tax? Is the question how do you find the answer?

Answers

so percent means parts out of 100 so
7%=7/100=0.7/10=0.07/1=0.07

so we want to find 12.50 +7% of 12.50

'of' can be translated as multiply



12.50+(0.07 times 12.5)=12.5+0.88=13.38

the total cost is 13.38

a shortcut is if you want to find cost+tax then
cost=1 and tax=0.07 so 1+0.07=1.07 so to find cost, just multply by 1.07

What is 345 written as a percent

Answers

Answer: 34500%.

Step-by-step explanation:

When we convert a number into percent , we multiply it by 100.

For example:  To convert 0.56 into percent, we have

0.56*100=56\%

Let's take one more example , to convert 12 into percent , we have

12*100=1200\%

The given number : 345

So to convert 345 into percent , we just multiply it by 100 , we get

345*100=34500\%

Hence, 345 is 34500%.

Thus , the correct answer is 34500%.
I think this is correct 345 = 34500%

Answers

Answer: the answer is 16.8

Step-by-step explanation: if you simplify you get 10.08 and 0.6

then if you do process of elimination to weed out the non answers by multiplying each option by 0.6 to find the one that equals 10.08 you get 16.8

0.6 x 16.8 = 10.08
I think the answer going to be 16.8
