Answer:

48.56 cm

Step-by-step explanation:

The rectangle: 10+10+8+8

= 36cm

The half circle: 1/2 πd

=1/2x3.14X8

= 12.56

So, the total perimeter will be- 36+12.56

=48.56

Mark me brainliest plss :)) I worked hard for the ans

Answer:

40.565cm

Step-by-step explanation:

To find a circumference (perimeter) of a cirlce, you need to use the formula C=2πr.

We know the diameter is 8 but we need the radius, the radius we would divide the diameter in half.

8 ÷ 2 = 4

Now that we know the radius is 4, you plug in 4 for r, and then solve

C= 2π4

C= 25.13

The circumference of the whole circle is 25.13 so we would cut it in half to get the half of the circle we need. So 25.13 ÷ 2 = 12.565.

Now that we have the circumference of the half-circle, it a lot easier. Take the 3 other sides and the half-circle and just add the together

8 + 10 + 10 + 12.565 = 40.565

Explanation:

Refer to the table below (attached image). I've copied your table and added a third row at the bottom. This new row is the result of multiplying each payout value with the corresponding probability.

Example: for the first entry of this row, have 2*0.45 = 0.9

Once that third row is filled out, you add up everything in that row. That will lead to the expected value.

The expected value is: 0.9+1.2+0.6+0.8+0.5 = 4

Interpretation: You expect, on average, to win $4 each time you play the game. This assumes that the cost to play the game is 0 dollars. If the cost is something else, then it will affect the expected value.

Because the expected value is not 0, this game is not mathematically fair (the bias is leaning in favor of the player).

Answer:

x = 0

Step-by-step explanation:

3(x - 2) + 15= -3(x - 3)

3x - 6 + 15 = -3x + 9

3x + 9 = -3x + 9

3x + 3x = 9 - 9

6x = 0

x = 0

Answer:

w = 4 and l = 9 or

l = 4 and w = 9

Step-by-step explanation:

let l = length

let w = width

2l + 2w = 26

lw = 36

l = 36/w

2(36/w) + 2w = 26

72/w + 2w = 26

(72 + 2w²) ÷ w = 26

cross-multiply:

2w² + 72 = 26w

2w² - 26w + 72 = 0

factor:

2(w² - 13w + 36) = 0

2(w - 4)(w - 9) = 0

w = 4 and l = 9 or vice versa

Answer:

No, Zahra does not have enough staff available

Step-by-step explanation:

Given

[tex]Ratio = 2 : 15[/tex] --- staff to people

[tex]Staff = 10[/tex]

[tex]People = 90[/tex]

Required

Are there enough staff?

Start by representing the data as a ratio

[tex]Ratio = Staff : People[/tex]

So, we have:

[tex]Ratio = 10 : 90[/tex]

Divide by 10

[tex]Ratio = 1 : 9[/tex]

Multiply by 2

[tex]Ratio = 2 : 18[/tex]

This means that, she has 2 members of staff for every 18 people (instead of the expected 2 to 15 people)

Hence, Zahra does not have enough staff available

Answer:

830

Step-by-step explanation:

7470/9 = 830

Answer:

900% of 7470=67230

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 7470 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 7470 is 100%, so we can write it down as 7470=100%.

4. We know, that x is 900% of the output value, so we can write it down as x=900%.

5. Now we have two simple equations:

1) 7470=100%

2) x=900%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

7470/x=100%/900%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 7470

7470/x=100/900

(7470/x)*x=(100/900)*x       - we multiply both sides of the equation by x

7470=0.11111111111111*x       - we divide both sides of the equation by (0.11111111111111) to get x

7470/0.11111111111111=x

67230=x

x=67230

now we have:

900% of 7470=67230

Answer:

$153 more

Step-by-step explanation:

50 x .36 = 18

50 + 18 = 68

50 x 8.5 = 425

68 x 8.5 = 578

578 - 425 = 153

Answer:

It will cost a total of $153.00 MORE

Step-by-step explanation:

If the planned amount was 50 people and 36% more showed up we would need to calculate 50x.36= 18. Then multiply 18 by the cost per person meaning 18x8.5=$153.00

Answer:

1.8cm²

Step-by-step explanation:

The shape shown is a rhombus with a height of 1.2 cm and  a base length of 1.5 cm.

The area of a rhombus can simply be calculated by multiplying the base length by the height

So area = 1.2 * 1.5

1.2 * 1.5  = 1.8

Hence the area of the rhombus is 1.8cm²

The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].

Step-by-step explanation:

We proceed to use the following trigonometric identity to derive an expression in rectangular form:

[tex]\cos^{2} t + \sin^{2} t = 1[/tex] (1)

Where:

[tex]\cos t = \frac{2-x}{3}[/tex] and [tex]\sin t = \frac{y-1}{4}[/tex]

Then, we expand the expression as follows:

[tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex] (2)

The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].

Answer:

A) (1+0.3)25

Explanation:

Zoe's expression 25+0.3(25) equals to 32.5. So the only expression that equals to 32.5 is A) (1+0.3)25.

Answer:

x=5

Step-by-step explanation:

All we have to do for this equation is cross multiply. This means we multiply 7 and 5 together and 5 and x+2 together. This will make the equation 35=5(x+2). Simplify this to get 35=5x+10. Subtract 10 from both sides to get 5x=25. You want to isolate x so you have to divide both sides by 5. This will make the equation x=5.

Step-by-step explanation:

The Answer is 75.36 cm

2 x (pi)3.14 = 6.28

6.28 x (r)3 = 18.84

18.84 x (h)4 = 75.36

The statement, "If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters." is true.

"A cylinder is a three-dimensional geometrical structure which consists of two circular bases connected with a curved surface."

For a cylinder with radius r and height h,

the curved / lateral surface area is,

A = 2 × π × r × h

Given: r = 3 cm, h = 4 cm

Using the formula for area of lateral surface of a cylinder:

⇒ A = 2 × π × 3 × 4

⇒ A = 24 × π

⇒ A = 24 × 3.14

⇒ A = 75.36 sq.cm.

Therefore, given statement is true.
