Waily purchased a desk that was on sale for 2/3 of The original price. If the original price was $450, what was the price that Wally paid?

Answers

Answer:

price Willy paid = $300

Step-by-step explanation:

Wally purchased a desk for 2/3 of the original price. The original price of the desk is given as $450. 2/3 of the actual price simply means 2/3 multiply by the original price.

original price = $450

To calculate 2/3 of $450.

2/3 × 450

multiply 2 by 450

= 900/3

divide 900 by 3

= $ 300

price Willy paid = $300

Change 2/3 to decimal point ( 2/3 = 0.67)
$450 x 0.67 = $301.50 (total sale price)
$450 - $301.50 = $148.50 (final price paid)

so, Wally paid $148.50 for the Desk.

the base of the pyramid in the diagram is a regular hexagon. The length of each side of the hexagon is 6 ft and the height of the pyramid is 6 ft . The area of the regular hexagon is 93.5 ft. What is the volume of the pyramid?

Answers

Answer:

The volume of the pyramid is $V=187\ ft^(3)$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=(1)/(3)BH$

where

B is the area of the base of the pyramid

H is the height of the pyramid

we have

$B=93.5\ ft^(2)$

$H=6\ ft$

substitute

$V=(1)/(3)(93.5)(6)=187\ ft^(3)$

Answer:The answer is 187 ft to the 3 power

The amount of rhubarb in the original recipe is 3 1/2 cups. Using what you know of whole numbers and what you know of fractions explain how you could triple that mixed number

Answers

Answer:

$10(1)/(2)$ cups.

Step-by-step explanation:

The amount of rhubarb in the original recipe is = $3(1)/(2)$ cups.

= $(7)/(2)$ cups

Using this amount we have to triple that mixed number.

So we have to multiply this fraction by 3.

$(7)/(2)$ × 3

= $(21)/(2)$

= $10(1)/(2)$ cups

We will get $10(1)/(2)$ cups when we triple the number of $3(1)/(2)$

Well first things first is you got to turn 3 1/2 into a mixed number. All i did was multiply 3x2 and added 1 which gave me 7 so that was my numerator. And for my denominator i kept the 2. So all you got to do now is multiply the fraction by 3 and make sure you put a 1 under 3. It gives you 21/2 so just divide that since its improper. And then your answer would be 10 1/2. Hope this helped you!
