Answer: X=8

Step-by-step explanation:

60                            96

5                                 x

5*96/60=8

Answer:

8

Step-by-step explanation:

Write a proportion :)

Choose 96 and x and 60 and 5, for example.

[tex]\frac{60}{5} = \frac{96}{x}[/tex]

your equation will be 60(x)=96x5

60x=480

divide and you get 8!

hope this helps :)

Answer:

Step-by-step explanation:

Question 1 is  2.

Answer:

Step-by-step explanation:

The area formula for a trapezoid would be b1+b2/2*height

So, 15+10/2*8

15+10=25

25/2= 12.5

12.5x8= 100 ft2

Therefore, Area equals 100 ft2

Answer:

100 ft.^2

Step-by-step explanation:

A =  a+b ÷ 2 • h

A = 15 + 10 ÷ 2 • h

A = 25 ÷ 2 • 8

100 = 25 ÷ 2 • 8

Answer:

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.

Answer:

10 sections

Step-by-step explanation:

Perform the following division to answer this question:

   2 1/2 ft

-------------------

1/4 ft/section

Convert 2 1/2 into an improper fraction with denominator 4:

 2 1/2 ft                  5/2 ft               10/4 ft

-------------------- = -------------------- = --------------------

 1/4 ft/section     1/4 ft/section      1/4 ft/section

This reduces to:

 10 ft

---------------- = 10 sections

1 ft/section

Hello! Answer: 116.64

Step-by-step explanation:

What I did was multiplied 5.4 by 7.2 by 6 and we get a total of 233.28 then we just divide by 2 so...

233.28 ÷ 2 = 116.64 HOPE THAT HELPS!

Answer:

Step-by-step explanation:

To find the volume of a three dimensional shape, you can multiply all three dimensions(length, width, and height).

Volume = 5.4 * 7.2 * 6

Volume = 233.28

If you round to the nearest tenth place, your answer is 233.28 inches cubed . However, if you think about a triangle, the area is base times height divided by two. Similarly, you have to divide the volume by two to get your final answer. Thus, your final answer is (C) 116.64

Answer:

= 2.75823202 quarts

Step-by-step explanation:

1.40513707 imperial quart = 64 US ounces

1.66534763 imperial quart = 8 cups

0.83267382 imperial quart = 2 US pints

1.40513707+1.66534763+ 0.83267382 = 3.90315852

conversion to gallons = 1.171875

2 - 1.171875 =0.828125

0.828125 gallons conversion x 3.33  = 2.75823202 quarts

2.75823202/0.828125  shows s the conversion rate from gallons to quarts

= 3.33

The answer is = 2.75823202 quarts

Answer:

Step-by-step explanation:

Volume =base area* hight

The base is a right triangle so area is (18*2)/2=36/2=18

Vol =18*3 =54 ft^2

Answer:

The value of y is 125 when x=25.

Step-by-step explanation:

It is given that y varies directly as x. It means y is proportional to x.

Where k is constant of proportionality.

It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.

Divide both sides by 5.

The value of k is 5.

The relation between x and y is defined by the equation

Put x=25 in the above equation.

Therefore the value of y is 125 when x=25.

Answer:

Half of a number is 15

Step-by-step explanation:

First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.

An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.

Twice as much as a number:              2X

12 less than a number:                        X - 12

Half of a number is 15:                        X/2 = 15

The difference of 20 and a number: 20 - X

As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

Answer:Ok so he makes about 6.00 bucks an hour so if he works 30 hours how much will he need to make 192.00 bucks.

Step-by-step explanation: Multiply 6.00 by 30 hours= 180 and u need 192$

so 192-180=12 so add 2 more hours to your 30 hours which makes it 32 hours.

If nick works 30 hours plus 2 more hours a week, he will make a total of $192.

Answer:

A) 9 cm

Step-by-step explanation:

By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.

In order to minimize the perimeter, we will assume that 4 cm is the longest side.

Thus, the two remaining sides must be greater than 4.

Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.

Hence, the smallest perimeter possible 9 cm.

Our answer is A.

Answer:
