Step-by-step explanation:

diameter of semicircle is 6 so radius is 6/2=3

so perimeter of the circle would be

p=2πr

p=2π*3=6π=18.8

But we have a semicircle so perimeter will be

P=p/2=18.8/2=9.4

The perimeter of the figure now would be

Perimeter=9+8+8+9.4=25+9.4=34 approximately.

The perimeter of the figure below, composed of an isosceles trapezoid and one semicircle is 34.4 units.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

From the given figure, equal sides of an isosceles trapezoid is 8 units, and parallel sides are 9 units and 6 units.

Radius of semicircle is 6/2 = 3 units

Now, perimeter = 9+8+8+Circumfrence of a semicircle

= 25+πr

= 25+3.14×3

= 25+9.42

= 34.4

Therefore, the perimeter is 34.4 units.

Answer:

6x-24

Step-by-step explanation:

First, we must add x-12 to 2x. We will get 3x-12. Now, to get the perimeter, we must multiply that expression by 2. The answer is 6x-24.

Answer:

1) x = -10

2) x = 39

3) x = 11

Step-by-step explanation:

1) x + 3 = -7

=> x= -7-3

=> x= -10

2) 2/3x + 1 = 27

=> 2/3x = 27 - 1

=> 2x =26 * 3 (26 multiply by 3)

=> x = 78/2

=> x =39

3) 4x-7 = 2 (x+3) +9

=> 4x-7 = 2x+6+9

=> 4x-2x =7+6+9

=> 2x = 22

=> x =22/2

=> x = 11

Answer:

I am expected to win $150

Step-by-step explanation:

We need to calculate the probability of drawing 2 black cards with replacement

There are 26 black cards in a deck of cards

The probability of drawing a black card is thus 26/52 = 1/2

So the probability of drawing two black cards in succession with replacement will be 1/2 * 1/2 = 1/4

So the probability of not drawing the two in succession will be 1 - 1/4 = 3/4

so out of twenty trials the number of times the drawing will occur will be 1/4 * 20 = 5 times

The number of times it will not occur will be 20-5 = 15 times

The amount my friend will win will be 5 * 30 = 150

The amount I will win will be 20 * 15 = 300

The amount I expect to win in the deal will be 300-150 = $150

Answer:

x= 2b-a

Step-by-step explanation:

Answer:

x=2b-a

Step-by-step explanation:

The first step is to subtract 2a from both sides to get the equation 2x=4b-2a

The next step is to divide by 2 so you can get x by itself which turns the equation to x=2b-a

Answer:

2x+y=−7

Step-by-step explanation:

Answer:

Step-by-step explanation:

From the information being provided;

We learnt that Becky pays simple interest at an annual interest rate of 8.8% which is calculated quarterly.

i.e. [tex]\dfrac{8.8\%}{4}= 2.2\%[/tex]

Since the first payment of $27,000 happened in the first three months, therefore, Becky will be able to have the money in the bank for 3 quarters prior to the lump-sum payment gets started.

Thus, the estimate of the amount Becky would earn as interest during this period of time is as follows:

[tex]I =\dfrac{PRT}{100}[/tex]

[tex]I =\dfrac{27000\times 2.2 \times 3}{100}[/tex]

[tex]I =\dfrac{178200}{100}[/tex]

I = $1,782

Answer:

He is wrong

Step-by-step explanation:

105≠ 50

10+10+10+10=50

5(10)= 50

To get 105 you would have to add 10 ten times and then add 5. Adding ten five times will only give you are value of 50.

Answer: 48s+12p-18 this is the correct answer i just took the test

The expression that represents the total cost can be written as -

y = as + pb - 18.

Given is that at the ski shack, customers can rent, skis, snowboards, boots, and poles by the day. Mrs. Alvarez is renting skis and poles.

Assuming the cost to rent skis for 1 day is $a and the cost of renting the poles is $b. Then we can write the expression that represents the total cost as -

y = as + pb - 18

Therefore, the expression that represents the total cost can be written as - y = as + pb - 18.

#SPJ2

Sum of two angles that are complementary = 90°

Let the smaller angle be x .

Then the larger angle = 2x

Let us make an equation to find the measure of both the angles :-

[tex]2x + x = 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30[/tex]

Which means :-

Measure of the small angle = 30°

Measure of the larger angle = 2 × 30 = 60°

Therefore , the measure of the bigger angle is 60° .

Step-by-step explanation:

i don't uderstand

Both these angles are vertically opposite angles due to which their angle measures will be equal .

Which means :-

[tex]12x + 9 =13 x + 1[/tex]

[tex]9 = 13x + 1 - 12x[/tex]

[tex]9 = 1x + 1[/tex]

[tex]1x + 1 = 9[/tex]

[tex]x + 1 = 9[/tex]

[tex]x = 9 - 1[/tex]

[tex]x = 8[/tex]

Which means :-

= 12 × 8 + 9

= 96 + 9

= 105°

= 13 × 8 + 1

= 104 + 1

= 105°

Therefore :-

angle 12x + 9 = 105° ( x = 8)

angle 13x + 1 = 105° ( x = 8 )
