To find the difference of 7 - 3 5/12 how do you rename the 7?

Answers

Answer 1

Answer: 3 5/12 is a mixed number, where 3 is a whole number and 5/12 is a fraction. Now you can tansform 7 in a mixed number with a fraction that contains 12 as denominator. The easiest way is using the fraction 12/12, which means that you make 7 = 6 and 12/12. Now you can subtract 6 12/12 - 3 5/12 by subtrancting the whole and the fractions by separate. 6 - 3 = 3 and 12/12 - 5/12 = 7/12. So the answer is 3 and 7/12 = 3 7/12.

Answer 2

Answer: We have to find the difference of 7 - 3 5/12. We will rename: 7 = 6 + 1 = 6 + 12/12 = 6 12/12. Then we will calculate: 6 12/12 - 3 7/12 = 3 7/12 ( we are now able to subtract the whole number from the whole number: 6 - 3, and the fraction from the fraction: 12/12 - 5/12 ). Answer: 7 = 6 12/12

Bruce rents snowmobiles to tourists. He charges $135 for 4 hours and $202.50 for 6 hours? What is the hourly rate Bruce charges to rent a snowmobile? Write a direct variation equation, then solve.

Answers

Answer:

The hourly rate Bruce charges is, $33.75

Step-by-step explanation:

Direct Variation states two variables that can be expressed by an equation in which one variable is equal to a constant times the other, or we can say that if one variable changes then the other changes in proportion to the other.

i.e $y \propto x$ or

y = kx where k is the constant.

Let x be the number of hours and y be the charges.

He charges $ 135 for 4 hours, by using direct variation;

⇒ $135= k( 4)$

Solve for k:

$k = (135)/(4) = \$ 33.75$ per hour

Now, for 6 hours he charges $ 202.50, by using direct variation.

⇒ $202.50 = k(6)$

Now, solve for above k: we have

$k = (202.50)/(6) = \$ 33.75$ per hour.

Therefore, the hourly rate Bruce charges to rent a snowmobile, k is, $ 33.75

Answer: Hourly rate of rent a snowmobile is $ 33.75.

Step-by-step explanation:

Since we have given that

Amount Bruce charges for 4 hours = $135

Amount Bruce charges for 6 hours = $ 202.50

Since there is direct variation, as with the increase in hours the cost will also increase.

So, it will be written like this :

$(135)/(4)=(202.5)/(6)$

But we need to find the hourly rate which will be

$(135)/(4)=\$33.75$

Hence, hourly rate of rent a snowmobile is $ 33.75.

Which property justifies this r(s + t) = rs + rt
statement

Answers

r(s+t) = rs + rt represents Distributive Property because r is multiplying s and t
i.e. ( r*s + r*t )
= rs + rt

So correct answer is Distributive Property.

A sixth grader weighs 90 pounds, which is 120% of what he weighed in fourth grade. How much did he weigh in fourth grade?

Answers

The weight in fourth grade was 75 pounds.

What is percentage?

A percentage is a value that indicates hundredth part of any quantity.

To convert percentage into a fraction it is divided by 100.

Given that,

The present weight of the sixth grader is 90 pounds,

And, the percentage of present weight with respect to fourth grade is 120%.

Suppose his weight in fourth grade was x pounds.

Now, the given problem can be written in the form of expression as below,

120% of x = 90

⇒ (120 / 100) × x = 90

⇒ x = 90 × (100 / 120)

⇒ x = 90 × (5 / 6)

⇒ x = 75

Hence, the weight of the sixth grader in fourth grade was 75 pounds.

#SPJ2

We have an equation: 90/? = 120/100

Cross multiply:
120*? = 90*100
⇒ ? = 90*100/120 = 75.

He weighed 75 pounds in fourth grade~
