Get Fit Gym currently has 96 members participating in their aerobic classes, and this number has been increasing by 2 people per
week. The cycling classes have a total of 80 members who participate, and this number
has been decreasing by 3 people per
week. In how many weeks will the number of people working out in the aerobics classes be double the number of people
attending the cycling classes?
Step-by-step explanation:
mx + b = y
2x + 96 = y
-3x + 80 = z
What we want is y to be twice z, or y = 2z
If we're going to make 2z, then that means its equation needs to be doubled as well:
2x + 96 = 2(-3x + 80)
2x + 96 = -6x + 160
8x = 64
x = 8
Now to check our answer:
2 * 8 + 96
16 + 96 = 112
-3 * 8 + 80
-24 + 80 = 56
56 * 2 = 112
hope it helps :)
2. Get the difference between 7 and the sum of 1.0006 and 4.06.
3
Given:
The difference between 7 and the sum of 1.0006 and 4.06.
To find:
The mathematical expression for given statement and it value.
Solution:
Sum of 1.0006 and 4.06 = [tex](1.0006+4.06)[/tex]
The expression for the difference between 7 and the sum of 1.0006 and 4.06 is
[tex]7-(1.0006+4.06)[/tex]
On simplification, we get
[tex]7-(1.0006+4.06)=7-5.0606[/tex]
[tex]7-(1.0006+4.06)=1.9394[/tex]
Therefore, the difference between 7 and the sum of 1.0006 and 4.06 is 1.9394.

A car rents for $280 per week plus $0.15 per mile. Find the rental cost for a three-week trip of 900 miles.
Answer:
$975
Step-by-step explanation:
The car is rented for 3 weeks
the rent is for a week is $280 so for three weeks it would be
3*28 = $840
now we need to add the per mile price to this
1 mile = $0.15 for 900 miles it would be
900*(0.15) = 135
So the total rental cost is
$840 + $135 = $975

A manufacturer makes chocolate squares that have a target weight of 8 g. Quality control engineers sample 30 chocolate squares to see whether H0: μ = 8 vs. Ha: μ ≠ 8 where μ is the true average weight of the chocolate squares. They calculate the sample mean of the 30 squares to be 8.3 g. Suppose the population standard deviation is 0.87 g and the true weight is 8.5 g. At the 5% level of significance, calculate the power for the test. For full credit, include all steps as described in class.
Using the normal distribution and the central limit theorem, it is found that the power of the test is of 0.9992 = 99.92%.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is [tex]\mu = 8.5[/tex].The standard deviation is [tex]\sigma = 0.87[/tex].A sample of 30 is taken, hence [tex]n = 30, s = \frac{0.87}{\sqrt{30}} = 0.1588[/tex].The power of the test is given by the probability of a sample mean above 8, which is 1 subtracted by the p-value of Z when X = 8, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{8 - 8.5}{0.1588}[/tex]
[tex]Z = -3.15[/tex]
[tex]Z = -3.15[/tex] has a p-value of 0.0008.
1 - 0.0008 = 0.9992.
The power of the test is of 0.9992 = 99.92%.

For the polynomial below,what is the power of the term with the coefficient of 1? x^3+1/3x^4+6x+5
Hi! I hope you're enjoying your day!
Please remember that the coefficient is the number before a variable.
Also, if we have no coefficient, then we have a coefficient of 1.
Here we have
x^3 (no coefficient)
the power is after the ^ symbol or written above a number (like [tex]\bold{t^h}[/tex]) where h is the power of t
Hence, the answer is
[tex]\boxed{\boxed{\bold{3}}}[/tex]
Hope everything is clear.

A triangular pane of glass has a height of 44 inches and an area of 440 square inches. What is the length of the base of the pane?
Answer:
20 inches
Step-by-step explanation:
The base, height, and area of a triangle are related by the formula ...
A = 1/2bh
If you know two of these, you can use this formula to find the third.
440 in² = 1/2b(44 in)
(440 in²)/(22 in) = b = 20 in . . . . . . divide by the coefficient of b
The length of the base is 20 inches.

Two similar solid cones have their radii 15cm and 25cm respectively, if the volume of the bigger cone is 325cm³. Calculate (a) the linear scale factor (b) the volume scale factor (c) volume of the smaller cone
Answer:
The length scale factor = \(\frac{24}{6} = 4\)
The area scale factor = \(4^2 = 16\)
\[\text{Larger area} = 16 \times \text{smaller area}\]
\[50.3 \times 16 = 804.8\]
The area of the large clock face is approximately 804.8 cm2.
Step-by-step explanation:
The length scale factor = \(\frac{24}{6} = 4\)
The area scale factor = \(4^2 = 16\)
\[\text{Larger area} = 16 \times \text{smaller area}\]
\[50.3 \times 16 = 804.8\]
The area of the large clock face is approximately 804.8 cm2.
Answer:
a) the linear scale factor = 5/3
b) the volume scale factor = 125/27
c) 70.2 cm³
Step-by-step explanation:
r₁ = 15 cm, r₂ = 25 cm
r₂/r₁ = 25/15 = 5/3
They are similar, so h₂/h₁ = 5/3
a) the linear scale factor = 5/3
b) the volume scale factor = (5/3)³ = 125/27
c) V₂/V₁ = 125/27
Given V₂ = 325 cm³, V₁ = 325*27/125 = 70.2 cm³

Working together, Bill and Tom painted a fence in 8 hours. Last year, Tom painted the fence by himself. The year before, Bill painted it by himself, but took 12 hours less than Tom took. How long did Bill and Tom take, when each was painting alone?
Answer:
Tom paints the fence in 24 hours and Bill paints the fence in 12
Step-by-step explanation:
T = 1 fence / x hours
B = 1 fence / x - 12 hours
B + T = 1 fence / 8 hours
( 1 fence / x - 12 hours ) + ( 1 fence / x hours ) = 1 fence / 8 hours
( 1 / x - 12 ) + ( 1 / x ) = 1 / 8
multiply through all the denominators to get:
8x + 8 (x - 12 ) = x( x - 12 )
8x + 8x - 96 = x^2 - 12x
combine like terms to get:
x^2 - 28x + 96 = 0
factor to get:
( x - 4 ) ( x - 24 ) = 0
x = 4, 24
4 won't work, because that would mean Bill would take a negative amount of time to paint the fence by himself, so that means
Tom paints the fence in 24 hours and Bill paints the fence in 12

Solve this system of equations algebraically:
y – 10 = 11x + x2

The first solution is (–4, –18).
The second solution is
Answer:
5,90
Step-by-step explanation:
got it correct :)
The second solution for the system of equations is (5, 90).
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given the system of equations,
y - 10 = 11x + x² and
y - 12x = 30
Consider second equation.
y - 12x = 30
⇒ y = 30 + 12x
Substitute y = 30 + 12x in the equation y - 10 = 11x + x², we get,
(30 + 12x) - 10 = 11x + x²
12x + 20 = 11x + x²
12x - 11x - x² + 20 = 0
-x² + x + 20 = 0
x² - x - 20 = 0
Discriminant = [tex]\sqrt{(-1)^{2} -(4*1*-20)}[/tex] = √(1 + 80) = √81 = ±9
x = (1 + 9)/2 and x = (1 - 9) / 2
x = 5 and x = -4
The solution x = -4 and y = -18 is given.
Other solution is,
x = 5
y = 30 + 12x = 30 + 60 = 90
Hence the second solution is (5, 90).
