Out of 20 words, Janet spelled 10 of them correctly. What percent of the words did Janet spell correctly?

The fraction \frac{10}{20} represents the 10 words that Janet spelled correctly out of all the words she spelled.

To find out what percent of the words that Janet spelled correctly, we can turn \frac{10}{20} into a percent.

Before we turn it into a percent, we can reduce it by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 20 using 10.

10 ÷ 10 = 1

20 ÷ 10 = 2

1 ÷ 2 = 0.5

0.5 × 100 = 50%

Therefore, Janet spelled 50% of the words correctly.

A model rocket was built using a scale factor of 1:15 if the height of the actual rocket is 9.9m, what is the height of the mill
beks73 [17]

Answer:

660 mm

Step-by-step explanation:

we know that

The scale factor is \frac{1}{15}

That means

1 unit in the model represent 15 units in the actual

or

1 m in the model represent 15 m in the actual

To find out the height of the model rocket, divide the height of the actual rocket by 15

so

9.9\ m=\frac{9.9}{15}= 0.66\ m

Convert m to mm

Remember that

1\ m=1,000\ mm

To convert meters to millimeters, multiply by 1,000

so

0.66\ m=0.66(1,000)=660\ mm

kolezko [41]

Q)You are going to movies Friday night. which of the theaters will cost the least, if you intend to have soda and popcorn?

    Theater A Theater B  Theater C

Adults $6.25   $7.25       $5.25

Children  $3.50   $3.75       $4.25

Soda $2.00   $2.00        $2.50

Popcorn $2.50   $2.00        $2.50

Answer:

Theater B will cost less.

Step-by-step explanation:

The question here does not tell how many adults and children are going so we will only calculate the price for soda and popcorn for the theaters above.

For Theater A:-

$2.00 + $2.50 = $4.5

For Theater B:-

$2.00 + $2.00 = $4

For Theater C:-

$2.50 + $2.50 = $5

Hence Theater B will cost less.
