Answer:

answer is 1 metre

Step-by-step explanation:

We can assume the width be 'x'

Now we would get the equation

(2x+10)(2x+14)=192

on solving we get x=1

Answer:

1207

Step-by-step explanation:

Total number of customers last week: 92 + 5 + 25 = 122

Number of customers who paid cash: 92

Percent of customers who paid cash last week: 92/122 × 100% = 75.4%

Next week:

Total number of customers: 1600

Expected number of customers paying cash:

75.4% of 1600 = 0.754 × 1600 = 1207

The 90% confidence interval for the population mean of the considered population from the given sample data is given by: Option C:  [130.10, 143.90]

Suppose that we have:

Then the confidence interval is obtained as

[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}}[/tex]

For this case, we're given that:

At this level of significance, the critical value of Z is: [tex]Z_{0.1/2}[/tex] = ±1.645

Thus, we get:

[tex]CI = \overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}}\\CI = 138 \pm 1.645\times \dfrac{34}{\sqrt{90}}\\\\CI \approx 138 \pm 5.896\\CI \approx [138 - 5.896, 138 + 5.896]\\CI \approx [132.104, 143.896] \approx [130.10, 143.90][/tex]

Thus, the 90% confidence interval for the population mean of the considered population from the given sample data is given by: Option C:  [130.10, 143.90]

Answer:

$1.5 per water bottle.

Step-by-step explanation:

One energy bar is equal to $2.

$2 * 22 players is equal to $44.

$44 - $77 is equal to $33.

$33 ÷ 22 players is $1.5.

the reason I divided $33 by 22 players is because you need to know how many dollars did he pay for each bottle of water so you divide the amount of dollars by the amount of players to get the amount of dollars of each water bottle.

Step-by-step explanation:

use the above process and answer is $3.60

The actual length the ball can travel in one rotation of 230 degrees is approximately 24.06 feet.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

We are given that;

The angle= 230 degrees

Radius of rope= 6ft

Now,

If the tether ball is tied to a rope with a radius of 6 ft and can rotate 230 degrees, then the length of the rope that the ball travels in one rotation can be found using the formula for the circumference of a circle, which is:

C = 2πr

where C is the circumference of the circle, r is the radius of the circle, and π is the mathematical constant pi (approximately equal to 3.14).

To find the length the ball can travel in one rotation of 230 degrees, we first need to convert 230 degrees to radians by multiplying it by π/180.

230 degrees * π/180 ≈ 4.01 radians

Now we can calculate the length of the rope that the ball travels in one rotation of 230 degrees using the formula:

L = rθ

where L is the length of the rope traveled by the ball, r is the radius of the circle (the length of the rope), and θ is the angle traveled in radians.

L = 6 ft * 4.01 radians

L = 24.06 ft

Therefore, by the given angle the answer will be approximately 24.06 feet.

Broker q’s commission with a charge of $32.50 will be $11.50 less than broker p’s commission of 4.4%

A bond is a fixed-income instrument that represents a loan made by an investor to a borrower.

Par value of bond = $1,000

Commission on this by broker p= 4.4% = 1000*(4.4)/100= $44

So, the total price spent to purchase this bond = $1044

Par value of bond = $1,000

Commission on this by broker q= $32.50

So, the total price spent to purchase this bond =1000+32.50 = $1032.50

Difference between both deals = 1044-1032.50 = $11.50

Therefore, broker q’s commission will be $11.50 less than broker p’s.

Answer:

1. Find the circumference, then multiply that by 120 turns.

Formula for circumference;

C = 2πr

But, we need to find the radius which is 1/2(half) of the diameter, so,

D/2 = R

D = Diameter

R = Radius

20/2 = 10 is the radius.

Plug in values now:-

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8 is the circumference, now we multiply this by 120 to get the total amount of centimetres it'll go.

62.8(120)

= 7,536 cm it'll go.

2. Find the circumference, then multiply that by 750 turns/revolutions.

C = 2πr

Find radius,

D/2 = R

50/2 = 25 is the radius.

Plug in values now:-

C = 2(3.14) x 25

C = 6.28 x 25

C = 157 cm it'll go.

3. Same thing, find circumference then compare values.

Given that radius is 10,

Use the formula for circumference;

C = 2πr

Replace values:-

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8 cm is the circumference of the first circle.

Now the second circle, (use same formula)

C = 2πr

Find radius,

D/2 = R

10/2 = 5 is the radius.

Replace values:-

C = 2(3.14) x 5

C = 6.28 x 5

C = 31.4 cm is the circumference for the second circle.

Now subtract the second circle's circumference from the first:

62.8 - 31.4

= 31.4, 31.4 cm is how much greater the second circle is than the first.

4 - 5. Find circumference, (using circumference formula)

C = 2πr

Find radius,

D/2 = R

760/2 = 380

Replace values:-

C = 2(3.14) x 380

C = 6.28 x 380

C = 2,386.4 km is the distance he'll travel.

If he wants to travel around it with 2,000 km, he'll need to travel at least once.

Answer:

a, 1/4

b, 75%

Step-by-step explanation:

a, total mins meant to be played = 80mins

mins being played = 20mins

fraction of the match being played = 20 /80 = 1/4

b, percentage of the match left to be played

= 80 - 20 = 60

then we find the fraction of the match meant to be played

60 / 80 = 3 /4

then we multiply by 100 to get the percentage

3/4 × 100 = 75 %

Answer:

56x

Step-by-step explanation:

Think of it an a triangle and a rectangle. The area of the rectangle is obviously 13 x 4x, which is 52x

for triangle, the hypotenuse is C, Right hand side is B and the side that is in the shape is B.

Area of triangle = (bh) / 2

B = 13 - 9, so B = 4

A = 6x - 4x, so A = 2x

the area is 2x x 4, which is 8x.

8x / 2 = 4x

The area is 4x + 52x, so the final answer is 56x
