Sarah can eat 45 blueberries in 2 minutes. If she eats blueberries for 45 minutes straight, how many did she eat?

BARSIC [14]

Answer:

1012

Step-by-step explanation:

She eats 1012 because:

If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.

This is because 45 ÷ 2 = 22.5

Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45

22.5 × 45 = 1012.5

She ate 1012 full berries.

in a given classroom the number of girls is 10 greater than number of boys if the ratio of the number of girls to the number of

Xelga [282]

Answer:

a) 35, b) 25, c) 60

Step-by-step explanation:

The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.

Number of boys: b

Number of girls: b + 10

Ratio of girls:boys is 7:5, so

$\frac{b+10}{b}=\frac{7}{5}$

"Cross multiply" to get

$7b=5(b+10)\\7b=5b+50\\2b=50\\b=25$

There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.

That's a packed classroom!

Larry buys a tent that is on sale for 25% off the original price. The original price is $80 more than the sale price. What is th

myrzilka [38]

Answer:

The original price of the tent = $320

Step-by-step explanation:

Let the original price be =$ $x$

Discount offered = $25$ % of the orignal price = $\frac{25}{100}\times x=0.25\times x =\$ 0.25x$

Original price is $80 more than sale price

Discount = Original price - Sale price = $80

So, we have

$0.25x=80$

We need to solve for $x$ to find original price

Dividing both sides by $0.25$

$\frac{0.25}{0.25}x=\frac{80}{0.25}\\x=\$320$

∴ The original price of the tent = $320

Laura is bowling 5 games. Her first 4 scores were 118, 128, 124, and 98. To end up with an average score of at least 123.2, what

BartSMP [9]

Answer:

148

Step-by-step explanation:

Average = sum of numbers /total numbers

let x = 5th number

123.2 = (118+ 128 + 124,+ 98 + x) / 5

123.2 = (468 + x) / 5

Multiply both sides by 5

616 = 468 + x

x = 148
