Answer:
(6,9)
Step-by-step explanation:
Y=2/3x+5
Y=x+3
2/4x + 5 = x + 3
Solve the equation
x=6
Substitute the value of x
y=6+3
Solve the equation again.
Now we know y=9
(x,y) = (6,9)
Check the solution
9=2/3 x 6 + 5
9=6+3

A vehicle travels on the highway at a rate of 55 mi/hr. How long does it take the vehicle to travel 45 miles?
Answer:
speed = 55mi/HR, distance is 45 miles and time is not given so what we are finding is the time the vehicle used when travelling 45miles at a rate of 55mi/hr. distance=speed×time. 45=55×time(t). 45=55t. now divide 45 by 55t to get time. which is 0.82.

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
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.

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
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.

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?
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.

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.
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.

2(8x) + 2(8x) = 16x + 16x = 32x.
rectangle
2(4x + 10) + 2(14) = 8x + 20 + 28= 8x + 48
32x = 8x + 48

24x = 48
divide both sides by 24
x = 2

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.
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]
