The expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

In order to calculate the expression, we need to use the PEMDAS rule which states:

From the question, we are to get the expression equal to 13.

From the given expression,(18 ÷ 2) + 6 ÷ 6 + 3 is equivalent to 13;

(18 ÷ 2) + 6 ÷ 6 + 3

9 + 6  ÷ 6 + 3

9 + 1 + 3

13

Hence the expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

Answer:

You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.

Step-by-step explanation:

First, write down the essentials of this word problem.

The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.

The owner needs 5 gallons (640 ounces) of the mixture.

The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).

The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.

0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.

0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.

This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.

CHECKING WORK:

6.3366 + 633.6633 = 639.99999997

OR ROUNDED:

6 + 634 = 640

Answer:

5225 x 5/100 = 261.25

5225 - 261.25 = 4963.75

Step-by-step explanation:

We know that % means a 100 so if they say they allowed a 5% discount then that would be 5/100.

You will take the fraction and multiple it with the original price. It will then give you the discount price, you will then need to subtract the discounted amount from the original sale price which is 5225. Then you will get your final answer.

Answer:

The least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].

Step-by-step explanation:

Let be the following rational expressions:

[tex]\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}[/tex]

Then, we factor each denominator:

[tex]\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}[/tex]

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:

[tex]\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)[/tex]

[tex]\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)[/tex]

Hence, we conclude that least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].

Answer:

k = 3.33

Step-by-step explanation:

x = 2

y = 3

x - ky + 8 = 0

2 - k(3) + 8 = 0

2 - 3k + 8 = 0

10 - 3k = 0

-10         -10

-3k = -10

k = 3.33

Answer:

x−ky+8=0=k=x/y+8/y

k=2/3+8/3 =3.266

Answer:

16.8 cubic centimeters

Step-by-step explanation:

3 cm * 4 cm * 1.4 cm = the volume of the prism

3 * 4 = 12

12 * 1.4

1 + 0.4 = 1.4

12 * 1 = 12

12 * 0.4 = 4.8

12 + 4.8 = 16.8

the volume of the prism is 16.8 cubic centimeters

Complete Question

The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?

Answer:

16 sides

Step-by-step explanation:

The sum of angles in a polygon formula is given as:

(n - 2)180°

Where n = Number of sides of the polygon

Hence:

(n - 2)180°= 2520°

Divide both side by 180°

(n -2) = 2520/180

n - 2 = 14

n = 14 + 2 = 16

Therefore the number of sides the convex polygon has 16 sides.

Answer:

The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .

The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .

Step-by-step explanation:

2.76% + 2.86% + 3.44% + 2.65% = 11.71%

11.71 / 3.44 = .2937

.2937 = 29.37%

Answer:

  39 units

Step-by-step explanation:

The angle markings tell you this is an equilateral triangle, so all sides are the same length.

  10x -11 = 2x +29

  8x = 40

  x = 5

Then the side length is ...

  2x +29 = 2·5 +29 = 39

The length of side KL is 39 units.

Answer: 80

Step-by-step explanation:

If you look at the top left and bottom right corner, you see that they are identical, so basically you would do the same to 80.

Well lets see...

Solution 1. The sum of angles of a quadrilateral is 360˚ 100˚+100˚+80˚=280 degrees 360˚-280˚=80˚.

Solution 2. Opposite angles on a parallelogram are equal so x=80˚.

Start by assigning a variable name to the "number" -- call it x.

Now write out what they say:

"The product of 1/3 and the sum of a number and 3" -- that's 1/3 times x + 3, or (1/3)(x + 3) or (x + 3) / 3

It's "between negative one and five"

So that means:

-1 < (x + 3) / 3 < 5

So now solve this inequality.  First multiply everything by 3.

-3 < x + 3 < 15

Subtract 3 from all the terms:

-6 < x < 12

So the answer is, all numbers between -6 and 12

Step-by-step explanation:

Because the area is 64 and the base is 4, then you would have to divide 64 by 4 to get 16 which is the height!

Answer:

it would be C. h=32 cm

Step-by-step explanation:

the formula for area of a triangle in A=1/2*b*h

so plug what you know into the formula, you know the area, A, and the base, b, so:

64=1/2*(4)*h

now solve what you can:

64=2h

then divide each side by 2 to get h, or the height, alone:

32=h

so, the height is 32 cm!

Answer:

Step-by-step explanation:

When you do 45 divided by 9 you get 5.

                         45 / 9 = 5

     To figure out what the smaller number (in this the 4) equals,

  you have to do 4 times 9 to get 36.

                    4 * 9 = 36

So your answer is 36.
