One hose can fill a small swimming pool in 65 minutes. A larger hose can fill the pool in 60 minutes. How long will it take the two hoses to fill the pool working together?

Answers

22 minutes 44 seconds

Step-by-step explanation:

1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min

2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min

Together Time taken = n min/job ; invert to get rate = 1/n job/min

------------------

Equation :-

Rate + Rate = together rate

1/65 + 1/35 = 1/n

-----------------------------

35n + 65n = 35*65

-----------------

100n = 2275

n = 22.75 minutes = 22 minutes 45 seconds

Answer:

  C.

Step-by-step explanation:

The transformation ...

  g(x) = f(ax)

represents a horizontal compression of the graph by a factor of 'a'. Here, the original function graph is compressed by a factor of 3 horizontally, so the curve will look a lot narrower.

The appropriate choice is C.

The indoor climbing gym is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 12 buses with 504 students. High School B rented and filled 2 vans and 4 buses with 184 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.

Answers

High school A:  3 vans + 12 buses = 504 students

High school B: 2 vans + 4 buses = 184 students

Multiply High school B by 1.5:

High school B: 3 vans + 6 buses = 276 students

Subtract High school B from High School A:

6 buses = 228 students

Divide students by buses:

Buses = 228 / 6 = 38 students per bus

Now solve for vans using high school A:

3 vans + 12(38 students per bus) = 504 students

Simplify:

3 vans + 456 students in buses = 504 students

Subtract students in buses from both sides:

3 vans = 48

Divide both sides by 3:

Vans = 16

Answer: vans = 16 students, buses = 38 students

Kennedy has a bag that contains strawberry chews, apple chews, and lime chews. She
performs an experiment. Kennedy randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Kennedy performs the experiment 38
times. The results are shown below:
A strawberry chew was selected 18 times.
A apple chew was selected 11 times.
A lime chew was selected 9 times.
Based on these results, express the probability that the next chew Kennedy removes
from the bag will be a flavor other than apple as a decimal to the nearest hundredth.

Answers

Answer:

0.71

Step-by-step explanation:

Based on what we see here, we can deterime the probability of each flavor being drawn.

Apple: 11/38

Strawberry: 18/38

Lime: 9/38

So the probability of an apple NOT being drawn is 27/38. This is about 0.71.

Hope this helps!

Answers

We can see 10/3 is an improper fraction. This can be represented as a mixed number that will have a whole number as well as a fractional part. The quotient of 10 divided by 3 is 3 While the remainder of 10 divided by 3 is 1.

Thus, 10/3 in a mixed fraction is 3 1/3.

Angles DUT and VUD sum to VUT. We can create an equation to model this.

DUT + VUD = VUT

Now, let's plug our values into the equation.

24x + 5 + 46 = 35x - 4

Simplify the left side.

24x + 51 = 35x - 4

Subtract 24x from both sides and add 4 to both sides.

55 = 11x

Divide both sides by 11.
