Answer:

answer is 52 cm

Step-by-step explanation:

BA = 17, BF = 6, and CG = 9

triangle sides BF and BH are congruent because they are tangent lines along the same curve

BH is equal to 6 since BF is equal to 6

this applies to CG and CF and AG and AH

CG is equal to 9

so CF is equal to 9

now we add 6 + 9 for the measurement of side CB

CB = 15

now we do the same for the other two sides

we already know BA = 17 so we subtract it from BH = 6 to find the measurement of AH

AH is equal to 11 and is tangent across the same curve as AG

AG = 11

now we add AG to CG

11 + 9 = 20

now we know all the side lengths

CB + BA + AC = Perimeter

15 + 17 + 20 = 52

Perimeter of triangle BCA = 52

I don't know why I went through all the trouble if I know no one is going to see this :'(. I just thought the other guy gave the wrong reasons

A department store sells logo shirts at an original price of $20. Every month that a shirt doesn’t sell, the store reduces the s

Tasya [4]

Given:
Original price = 20
reduces selling price by 25% every month it's not sold.

First markdown month:
20 * (100%-25%) = 20 * 75% = 15

Second markdown month
15 * 75% = 11.25

Macy, employee gets a 50% discount off the current price.
11.25 * 50% = 5.625
11.25 - 5.625 = 5.625 or 5.63

The pre-tax price of the shirt for Macy will be $5.63

High school students from track teams in the state participated in a training program to improve running times. Before the train

Nataly [62]

Answer:

b. The values X and Y are independent therefore, the mean is 34 seconds and the standard deviation is 50 seconds

Step-by-step explanation:

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Before the training, the mean running time for the students to run a mile was 402 seconds with standard deviation 40 seconds.

This means that $\mu_X = 402, \sigma_X = 40$

After completing the program, the mean running time for the students to run a mile was 368 seconds with standard deviation 30 seconds.

This means that $\mu_Y = 368, \sigma_Y = 30$

Which of the following is true about the distribution of X-Y?

They are independent, so:

$\mu = \mu_X - \mu_Y = 402 - 368 = 34$

$\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{40^2+30^2} = 50$

This means that the correct answer is given by option b.

The total operating costs of a monorail are paid using a combination of passenger fares and tax revenue. The farebox recovery ra

Vadim26 [7]

Answer:

0.57 or 0.56

Step-by-step explanation:

passenger fares + tax revenue = operating costs

Thus:

passenger fares = operating costs - tax revenue

= $69 million - $30 million

= $39 million

The ratio of passenger fares to total operating costs is:

$39 million

= 0.5652.

$69 million

To the nearest hundredth, the farebox recovery ratio is 0.57.

Someone help! you have 44 text messages in your inbox. How many messages can your cell phone hold? (and inbox is 88% full)

marin [14]

We can set up a proportion.

88% = 0.88

44/0.88 = x/1

Cross multiply:

0.88x = 44

Divide 0.88 to both sides:

x = 50

So your cell phone can hold 50 messages.
