Answer:

6.75

=> 675/100

=> 135/20

Answer:

15.83

Step-by-step explanation:

13.11 / 100 = 0.1311

0.1311*5=5%=0.6555

13.11+0.6555=13.7655

13.7655/100=0.137655 * 15 -->15%=2.064528

13.7655+2.064528=15.830325

86.6666666667

Step-by-step explanation:

Because one of Tom's car wheel weighs 21 2/3 pounds, you would have to multiply 21 2/3 pounds by 4 to get the amount of pounds that all the tires weigh; which makes the answer:86.6666666667

Answer:

86 2/3

Step-by-step explanation:

you multiply 21 × 4 and get 84

multiply 2 × 4 and get 8

Divide 8/3 and get 2 2/3

add 2 to 84

parallelogram

Step-by-step explanation:

Looks like a rectangle, but then angles should be marked =90

But two sides are marked equal that makes it a parallelogram.

(a parallelogram is 4 sided figure where 2 opposite sides are =

Answer:

The side lengths of the larger polygon are;

15 cm

20.625 cm

16.875 cm

9.375 cm

13.125 cm

Step-by-step explanation:

Firstly, we need to calculate the perimeter of the first polygon

Mathematically, we can get this by adding the side lengths together

We have this as;

5 + 7 + 8 + 11 + 9

= 40 cm

so we have the ratio of the lengths of both as;

75 cm/40 cm = 1.875

Now, we simply will multiply the lengths of the smaller polygon by 1.875

So we have the side lengths of the bigger polygon as;

1.875 * 5 = 9.375 cm

1.875 * 7 = 13.125 cm

1.875 * 8 = 15 cm

1.875 * 9 = 16.875 cm

1.875 * 11 = 20.625 cm

Answer:

4(5 + 6)

Step-by-step explanation:

Factor out the GCF (4):

20+24 = 4(5 + 6)

Answer:

The median is 2

Step-by-step explanation:

Here, we want to get the median for the number of pencils

Firstly, we have to write out the numbers that form the box plot ; we have this as;

1,1,1,2,2,2,2,3,3,5

the median is sum of the 5th and 6th term divided by 2

The 5th term is 2

The 6th term is 2

So the median is;

(2 + 2)/2

= 4/2 = 2

Answer:

(150-36π) ft^2

Step-by-step explanation:

we need to subtract the area of the circle from the area of the trapezoid to find the area of the shaded region.

area of circle=πr^2=π6^2=36π ft^2

area of trapezoid=(1/2)(a+b)h=(1/2)(12+13)12=150 ft^2

so, the area of trapezoid-area of circle=(150-36π) ft^2

Answer:

  -5x² -4x +8

Step-by-step explanation:

Eliminate parentheses and collect terms.

  (-2x² +3) -(3x² +4x -5)

  = -2x² +3 -3x² -4x +5

  = (-2-3)x² -4x +(3 +5)

  = -5x² -4x +8

-5x² -4x +8  

remove parentheses and collect terms.

 (-2x² +3) -(3x² +4x -5)

 = -2x² +3 -3x² -4x +5

 = (-2-3)x² -4x +(3 +5)

 = -5x² -4x +8

Answer:

No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.

Answer:

No

Step-by-step explanation:

It will not be because when a number is numtiplied by one, it stays the same. However, both of these are numbers less than 1, so the product will be smaller

Answer: D

Step-by-step explanation: get the variable by itself on one side of the inequality sign.

Get the variable by itself on one side of the inequality sign. Option D

Isolating a variable in an equation or inequality refers to changing it so that it is on its own on one side of the equation or inequality sign.

In order to remove any additional terms or factors that are affecting the variable, this entails applying different operations to both sides of the equation or inequality, such as addition, subtraction, multiplication, or division.

The objective is to make the inequality or equation simpler so that the variable can be solved more easily.

The complete question:

What does it mean to isolate the variable?

А: Evaluate the coefficient.

B: Reverse the inequality sign.

С: Get zero by itself on one side of the inequality sign.

D: Get the variable by itself on one side of the inequality sign.

Answer:

A

Step-by-step explanation:

a positive number times a negative number is equal to a negative number.

Because all negative numbers have a value less than 0 the inequality sign must face towards the 0

The inequality sign also must be a < or > not a ≤ or ≥ as no positive number times -11 will equal 0

so the answer would be x < 0

Answer:

The number is 1.6 .

Step-by-step explanation:
