Could anyone help me solve this problem ? It doesn’t have to be perfect

Answers

Answer 1

Answer:

x = 2

Step-by-step explanation:

If B and D are midpoints, then you have to similar triangles ACE and BCD that have a constant ratio on their corresponding sides.

That ratio is 1:2 for any side of triangle BCD compared to corresponding side on triangle ACE,

Then BD / AE = 1/2

cross multiplying:

2 * BD = AE

replacing with their expression in terms of x:

2 (5 x + 3) = 4 x + 18

using distributive property:

10 x + 6 = 4 x + 18

solving for x:

10 x - 4 x = 18 - 6

6 x = 12

x = 2

Which of the ratios below is equivalent to 2:1? Select all that apply.

A) 6:4
B) 8:4
C) 10:5
D) 6:12
E) 6:3

Answers

The ratios below that are equivalent to 2:1 is 8:4, 10:5 and 6:3. That is options B, C, and E.

To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.

Therefore in option B, when 8:4 is simplified by division,

8/4 = 2/1 = 2:1

Therefore, in option C, when 10:5 is simplified by division,

10/5 = 2/1 = 2:1

Therefore, in option E, when 6:3 is simplified by division, 6/3 = 2/1 = 2:1

Therefore, the ratios below that are equivalent to 2:1 is 8:4, 10:5 and 6:3.

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (4x + 10) units and a width of 14 units. What will be the perimeter of both the rectangle and square?

A. 34 units
B. 60 units
C. 64 units
D. 2 units

Answers

Answer:

the answer is d(2 units)

Answer:

C 64 units

Step-by-step explanation:

P = 2L + 2W

square

2(8x) + 2(8x) = 16x + 16x = 32x.

rectangle

2(4x + 10) + 2(14) = 8x + 20 + 28= 8x + 48

32x = 8x + 48

-8x -8x

24x = 48

divide both sides by 24

x = 2

P = 32(2) = 64

You have 48 minutes to exercise at the gym. The elliptical trainer burns 9 calories per minute, while the treadmill burns 8 calories per minute. You want to burn 400 calories total using both machines. How much time should you spend on each machine

Answers

Answer:

16 minutes on the elliptical trainer and 32 minutes on the treadmill.

Step-by-step explanation:

We have the following relation for the training in both machines:

[tex] 400 cal = 9 cal/min*t_{1} + 8 cal/min*t_{2} [/tex] (1)

Where:

t₁: is the time spent on the elliptical trainer

t₂: is the time spent on the treadmill

With:

[tex] t_{1} + t_{2} = 48 min [/tex] (2)

From equation (2) we have:

[tex] t_{1} = 48 min - t_{2} [/tex] (3)

By entering equation (3) into (1):

[tex] 400 cal = 9 cal/min*(48 min - t_{2}) + 8 cal/min*t_{2} [/tex]

[tex] 400 cal = 432 cal - 9 cal/min*t_{2} + 8 cal/min*t_{2} [/tex]

[tex] t_{2} = \frac{32 cal}{1 cal/min} = 32 min [/tex]

Now, we can find t₁:

[tex] t_{1} = 48 min - t_{2} = 48 min - 32 min = 16 min [/tex]

Therefore, you should spend 16 minutes on the elliptical trainer and 32 minutes on the treadmill.

I hope it helps you!

Consider random samples of size 50 from a population with proportion 0.35.
Find the mean and standard error of the distribution of sample proportions.
Round your answer for the mean to two decimal places, and your answer for the standard error to three decimal places.

Answers

Answer:

The mean is [tex]\mu_{\^ p } = p = 0.35[/tex]

The standard error is [tex]SE = 0.06745[/tex]

Step-by-step explanation:

From the question we are told that

The sample size is n = 50

The population proportion is [tex]p = 0.35[/tex]

Generally given that the sample size is large enough , then the mean of the distribution is mathematically represented as

[tex]\mu_{\^ p } = p = 0.35[/tex]

Generally the standard error of the distribution is mathematically represented as

[tex]SE = \sqrt{\frac{p (1- p )}{n} }[/tex]

=> [tex]SE = \sqrt{\frac{0.35 (1- 0.35 )}{50} }[/tex]

=> [tex]SE = 0.06745[/tex]

A truck driver averages 62 miles per hour while delivering freight to a customer. On the return trip, the driver averages 50 miles per hour due to construction. The total driving time is 7 hours. How long did the return trip take? Round your answer to the nearest tenth of an hour.

Answers

Answer: 7 h and 20 min

Step-by-step explanation:

The return trip: 50

And hour : 7

So 50/7= the total return trip

50/7 = about 7.1428

Round to nearest 10th

Equals 7.20 so 7 h and 20 min is the total time.

One tank is filling at a rate of 3/4 gallons per2/3 mins. A second tank is filling at a rate of 5/8 gallons per 1/2 mins. Which tank is filling faster?

Answers

9514 1404 393

Answer:

2nd tank

Step-by-step explanation:

The rate of filling, in gallons per minute, is found by dividing gallons by minutes.

Tank 1

(3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min

Tank 2

(5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min

10/8 gal/min is more than 9/8 gal/minute.

The second tank is filling faster.
