Answer
they worked 16.5 hours that week.
Step-by-step explanation:
You first subtract the tip by the total cost and that gives you $132.00. and from that cost you divide by $8 which they get paid by the hour... and then you get the 16.5 and that means they worked 16.5 hours that week.
If Jim Roller can paint a room in 3 hours while John Brush would take 5 hours, how long will they take if they work together? 1/8 hour 8/15 hour 1 7/8 hours
Answer:
Step-by-step explanation:
Each hour, Jim does 1/3 of the job if working alone.
Each hour, John does 1/5 of the job if working alone.
Let x = number of hours to do the job if they work together. So, each hour, they do 1/x of the job when they work together.
We get the equation: 1/3 + 1/5 = 1/x
Multiply the equation by the LCD, 15x: 5x + 3x = 15
8x = 15
x = 15/8 = 1 7/8 hrs

Paul wants to save $90 to go on a trip with his friends. He has $30 in his savings, and plans on saving $15 a week until he has enough money to go. Which of the equations below represents the situation?
Answer:
15 X w(how many weeks) + 30 = 90 or 15 X 4 + 30 = 90
Step-by-step explanation:
so he needs $90 he has $30 and he gets 15 a week so we are going to say a week will be w so however many weeks (4) so you will need to multiply it by 15 and it will be 60 then you add 30 and you get 90.

A news report says that 9% of middle school students are on the track team.
There are 600 students in your middle school.
How many students in your school would you expect to be on the track team?
Answer:
54 students.
Step-by-step explanation:
If you have 600 and 9% the nearest rounding point is %10. %10 of 600 is 60, and 1% of 60 is 6, so 60-6=54.
The graph below have the same shape . What is the equation of the red graph ?
A. G(x) = (7-x)^2
B. G(x) = 1-x^2
C. G(x) = 7-x^2
D. G(x) = (1-x)^2
Answer:
Option B is correct .
Step-by-step explanation:
According to Question , both the graph have same shape . If we look at the the first graph it cuts x - axis at (0 , 2) and ( 0 , -2) . Hence x = 2 and -2 are the zeroes of the equation .
And ,the given function is ,
[tex]\implies f(x) = 4 - x^2 \\\\\implies f(x) = 4-x^2=0 \\\\\implies 2^2-x^2=0\\\\\implies (2-x)(2+x) = 0 \\\\\boxed{\red{\bf \implies x = 2 , (-2) }}[/tex]
• Hence ,we can can see that x = 2 and (-2) are the zeroes of graph.
This implies that if we know the zeroes , we can frame the Equation.
On looking at second parabola , it's clear that cuts x - axis at ( 1, 0 ) and (-1,0). So , 1 and -1 are the zeroes of the quadratic equation . Let the function be g(x) . Here , a and ß are the zeroes.
[tex] \begin{lgathered}\implies g(x) = (x-\alpha)(x-\beta) \\\\\implies g(x) = (1+x)(1-x) \\\\\boxed{\pink{\bf \implies g(x) = 1 - x^2}}\end{lgathered} [/tex]
Hence option B is correct .
Identify the reciprocal of each number. Type it in the blank, using a slash () to show a fraction,
5/6
Answer:
Answer: 6/5
Step-by-step explanation:
When finding the reciprocal, we essentially just "flip" or take the inverse of the number we are given. For example, the reciprocal of 1/2 would be 2/1 or 2. The given number multiplied by the reciprocal should always equal 1. If it does, then we know we are correct.
In this case, we are finding the reciprocal of 5/6, so we "flip" the numerator and the denominator to get 6/5.
To check our work, we need to multiply our original number and its reciprocal.
5/6 x 6/5 = 30/30 = 1
Now, we know we are correct, that the reciprocal of 5/6 is 6/5.

Answer:
t = 17
s = 46
Step-by-step explanation:
Congruent Triangles
If two triangles are determined to be congruent, their side lengths and angles have the same measure.
We are given the condition that triangles HIJ and DCB are congruent. This implies that sides JH and DB have the same measure, thus:
s = 46
We can also say that sides IJ and CB have the same measure, thus:
t = 17
Discuss: a. The role of the expansion of 1/(1 - t) in powers of t in the explanation of the Basic Convergence Principle. b. The role of the Basic Convergence Principle in the explanation of the ratio test.
Answer:
See convergence analysis below
Step-by-step explanation:
For the expansion of 1/(1-t) in powers of t, we can recall that an infinite Geometric series with first term "1" and common ratio "t", in the case that the absolute value of "t" is smaller than 1, can be represented by:
[tex]\Sigma\limits^\infty_0\, t^n=\frac{1}{1-t} \\[/tex]
The condition for such, is that the absolute value of "t" is smaller than "1", which gives us the radius of convergence for this series "1" and the interval of convergence: - 1 < t < 1
Recall as well that using the geometric sequence [tex]1 + t + t^2 + t^3 +...[/tex]
The ratio test becomes [tex]\frac{a_{n+1}}{a_n} = t[/tex]
which is the SAME as the common ratio for the geometric sequence, and which in order to converge to the value [tex]\frac{1}{1-t}[/tex] requires that the absolute valu of the common ration be smaller than "1" rendering the same radius of convergence as discussed above.

One of the diagonals of a rectangle a 20 cm long. The difference between its length and its width is 4 cm. Find the area of the rectangle?
Answer:
A = 192 cm²
Step-by-step explanation:
Given that,
The length of the diagonal of a rectangle is 20 cm.
The difference between its length and its width is 4 cm.
Let the length is l and width is b.
ATQ,
l-b = 4 ...(1)
Let x is the diagonal of the rectangle such that,
[tex]x^2=l^2+b^2[/tex]
or
[tex]20^2=l^2+b^2\\\\l^2+b^2=400[/tex] ....(2)
Now we need to solve equation (1) and (2).
Squaring equation (1) : [tex]l^2+b^2-2lb=16[/tex]
Put equation (2) in above equation.
[tex]400-2lb=16\\\\400-16=2lb\\\\2lb=384\\\\lb=192[/tex]
Since, the area of the rectangle, A = lb
A = 192 cm²

In the figure a is parallel to b, what is the value of y?
Answer:
y = 60*
x = 30*
Step-by-step explanation:
the bottom angle is the same angle as y and it says 2x meaning that x is 1/2 of y. the full angle across the line is 180* so divide that by 3.
180 / 3 = 60

Find the average rate of change for the function over the given interval.
y=e^x between x=−2 and x=0
Answer:
The average rate of change for the function over the given integral
[tex]A(x) = \frac{e^{-2} -1}{2}[/tex]
Step-by-step explanation:
Explanation
Average rate of a function:-
We can define the average rate of change of a function from a to b
[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]
Given function f(x) = eˣ
Given interval x = a = -2 and y = b = 0
f(a) = f(-2) = e⁻²
f(b) = f(0) = e⁰
[tex]A(x) = \frac{e^{-2} -1}{0-(-2)}[/tex]
