denpristay [2]

Answer:

11

Step-by-step explanation:

since x>100, then 19-20x and 20-19x would obviously be negative and x-10 would be positive.

Therefore we have (20x-19)-(19x-20)-(x-10) = 20x-19-19x+20-x+10 = 11

Question 1

Find the missing side length.

5*5=25+ 7*7=49= 74 so 8.6

Question 2

What is the area of the parallelogram?

18*50=900

Question 3

What is the perimeter of the figure?

If you break the object apart. 7+7+1+1=16

5+5+3+3=16

16+16=32m

Question 4

What are the solutions to the equation?

x^2 – 22 = 14

I found that 6*6=36 – 22=14

I tried a few numbers .

Question 5

What is the area of the figure?

If you break the figure apart. 3*2=6

2*6=12

6+12=18cm

Question 6

What is the area of the trapezoid?

11+3=14*9=126*2=252

Question 7

Hint: 1 Revolution equals the Circumference!

How far does a wheel travel in 2 revolutions if it has a radius of 45 cm?

2*3.14=6.28*45=282.6*2=565.2

Question 8

The diameter of the larger circle is 11 cm.  The diameter of the smaller circle is 7 cm.  What is the area approximate area of the shaded region?

For the smaller one – 7/2= 3.5 *3.5*3.14=38.46

For the bigger one- 5.5*5.5*3.14=94.98

94.98-38.46=56.52

Question 9

What is the approximate area of a circular garden that has a diameter of 12 feet?

A= Pi*r2. 3.14*6^2 =113

6*6=36*3.14= 113.04

Question 10

A 17-foot pole is leaning against a wall.  The bottom of the pole is 8 feet away from the bottom of the wall.  Approximately how high up the wall does the top of the pole reach?

Easiest way to calculate 22% mark up from a cost of say 39.99
satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

  • The cost = 39.99 (Let say in $)
  • Mark up = 22%

As

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

so

Markup amount = 0.22 × 39.99

                           = 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $

CAN SOMEBODY HELP WITH THIS QUESTION ASAP​
tia_tia [17]

Answer:

The rectangles are not similar

Step-by-step explanation:

In order to check whether they are similar, we need to take the ratio of their similar sides and ensure they are equal to a constant k.

Hence;

AB/PL = AD/LM = k

32/26 = 18/12 = k

16/13 = 9/6 = k

Since the scale factor is not the same, hence the rectangles are not the same.
