Ratio = 3 : 4 : 7 -> nickels : dimes : quarters
Total = 112 coins

3 + 4 + 7 = 14 coins in the jar to begin with

112 : 14 ratio -> end total : beginning total

Note: ratios can also be expressed as divisions or fractions

So...

112 / 14 = 8

Now you have to multiply each coin in the ratio by 8 to determine how much there are in a total of 112.

Nickel: 3 x 8 = 24
Dime: 4 x 8 = 32
Quarter: 7 x 8 = 56

New ratio of coins in total of 112 is
24 : 32 : 56

You can check my adding them up:

24 + 32 + 56 = 112

The question asks how many nickels would there be if there were a total of 112 coins and we can see in the new ratio that there would be 24 nickels.

Therefore, there is 24 nickels in a jar if there were a total of 112 coins.

Answer:

There are 108 inches in 9 feet

Step-by-step explanation:

Well, two unit multipliers mean we have to convert through two units before we arrive at our final answer so we can convert from feet to yards to inches!

We know that 3 feet equal a yard, right?

So we can divide 9 by 3 to get the amount that 9 feet translates to in yards.

9/3 = 3!

So we are now done with our first conversion! Our second is going to be from yards to inches!

There are 36 inches in 1 yard so we should multiply 3 by 36 to get the amount in inches!

3*36 = 108!

1)x+30=40

x=40-30

Answer :x=10

2)30-20+2x=10

10+2x=10

2x=0

Answer: x=0

3)3x-10+13=-2x+28

3x+3=-2x+28

3x+2x+3=28

3x+2x=28-3

5x=28-3

5x=25

x=5

4)13x-23-45=-7x+12

13x-68=-7x+12

13x+7x-68=12

13x+7x=12+68

20x=12+68

20x=80

x=4

5)2(x+4)=10x+24

2x+8=10x+24

2x-10x+8=24

2x-10x=24-8

-8x=24-8

-8x=16

x=-2

6)3(x-5)=1-(2x-4)

3x-15=1-(2x-4)

3x-15=1-2x+4

3x-15=5-2x

3x+2x-15=5

3x+2x=5+15

5x=5+15

5x=20

x=4

If the area of the triangle is 48 square units, what is the total area of sections 1 and 2?
MariettaO [177]

Answer:

48 square unit

Step-by-step explanation:

For a rectangle, area is given by

A=bh

Where b is base and h is height as shown in the attached diagram

For a triangle, area is given by

A∆=½bh

Given that ½bh=48

Then bh=2*48=96 square units

The overall area is 96 square units.

The area for 1&2 combined will be given by deducting the area of triangle from the overall area

Area is 96-48=48 square units
