Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?
Answer:
10
Step-by-step explanation:
Rate of drainage for pump A and B = [1 pool drained]/[6 hours]
Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]
Rate for pump B (newer pump) = [1 pool drained]/[t hours]
Thus, adding the rate of drainage of A and B,
1/t + 1/15 = 1/6
t=10

Plz I really need help!! What is the measure of angle B in the triangle?
This triangle is not drawn to scale.
Enter your answer in the box.
mZB=
Answer:
70
Step-by-step explanation:
Hello There!
In order to find the measure of angle B we need to solve for x
Remember the sum of the angles in a triangle is 180
so we can solve for x using the equation
180=40+x+20+2x-30
step 1 combine like terms
40+20=60 60-30=30
2x+x=3x
now we have
180=3x+30
step 2 subtract 30 from each side
180-30=150
30-30 cancels out
step 3 divide each side by 3
150/3=50
3x/3=x
we're left with
x=50
Now we plug in 50 into x in 2x-30
2*50=100
100-30=70 so we can conclude that
angle B = 70

6. Write a formula to represent the nth term of the sequence: 3, 6, 12, 24, 48, 96,...
Given :
The sequence is given as : 3, 6, 12, 24, 48, 96,...
To Find :
A formula to represent the nth term of the given sequence.
Solution :
Breaking down each term we get :
3 = 3 × 2⁰ 1 - term
6 = 3 × 2¹ 2 - term
12 = 3 × 2² 3 - term
24 = 3 × 2³ 4 - term
48 = 3 × 2⁴ 5 - term
From above observation we can say that n th term is given by 3 × 2ⁿ⁻¹ .
Therefore, the nth them of the sequence is given by ( 3 × 2ⁿ⁻¹ ) .

Answer:
1) No
2) Yes
3) angle UXS = 120 degrees
4) arc CB = 40 degrees
Step-by-step explanation:
If AB is tangent to the circle, then angle at A would be 90 degrees.
1)
Is 13^2 + 14.6^2 = 19.4^2?
169 + 213.16 = 376.36 No
2)
Is 8^2 + 6^2 = 10^2?
64 + 36 = 100 Yes
3)
arc WS = arc VU + arc TU = 113 degrees
arc ST = arc WV because their chords cross making a pair of vertical angles.
full circle = 360 degrees
360-113 - 113 = 134 degrees
134/2 = 67 degrees for arc ST
arc STU = 67 + 53 = 120 degrees
Angle UXS = 120 degrees
4) arc CB = arc FB = 40 degrees because their chords cross making a pair of vertical angles.

someone helppp! This is due the day after tomorrow!!
Step-by-step explanation:
Given
(2x + 3 )² - (2x + 3) (x - 5)
= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))
= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )
= 4x² + 6x + 9 - 2x² + 10x - 3x + 15
= 2x² + 13x + 24

Consider the first five terms of the following sequence.
2, 6, 18, 54, 162, ...
If the sequence defines a function, what is a reasonable domain and range of the function?
O A. Domain: all real numbers; Range: all real numbers
B. Domain: {1, 2, 3, 4, 5, ...}; Range: {2, 6, 18, 54, 162, ...}
C. Domain: {1, 2, 3, 4, 5, ...}; Range: all real numbers
O D. Domain: all real numbers; Range: {2, 6, 18, 54, 162, ...}
Answer:
B. Domain: {1, 2, 3, 4, 5, ...}; Range: {2, 6, 18, 54, 162, ...}
Step-by-step explanation:
2, 6, 18, 54, 162
This is a geometric sequence because it is increasing by multiplication. The common ration of the sequence is *3.
Our sequence values will serve as the y-values, or the range, and our x-values will be the term number.
Domain, or x-values: {1, 2, 3, 4, 5, ...}
Range, or y-values: {2, 6, 18, 54, 162, ...}
It is not A or D because we can't have negative term values. "All real numbers" implies all positive and negative integers.
The range also cannot be all real numbers for the same reason.

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represents dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1
2
x. Explain who is correct.
Answer:
y=2x
Step-by-step explanation:
x=number of ticket sold y = dollars donated
for every 10tickets sold 5 dollars would be donated
10x = 5y divide both sides by 5
2x = y. same as. y = 2x.
