Which inequality represents all values of x for which the quotient below is
defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B.x great than or equal to 1
O C. x> 1
O D. x<-1
Answers
You can re-write this quotient this way :
[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1

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
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

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.

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

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.
5 = x
