Lila and Nina are at college and spending their savings. Nina has $1,500 and is spending $80 a week. Lila has $600 and is spending $20 a week. Write and solve an equation that will figure out how long it will take for them to have the same amount of money.
So you can take this as a sequence. For Nina the term would be 1,500 and second be 1,420. So the equation for it would be -80n + 1580. For Lila it would be -20n + 620. 1,500 and 600ths highest common factor is 300. So it would take Nina 16 weeks. For Lila it would take 16 as well.

Flex Gym charges a membership fee of $150 plus $40.50 per month to join the gym. A rival gym, Able Gym, charges a membership fee of $120 plus $46.75 per month.
Answer:
4.8 months
Step-by-step explanation:
150+40.50x=120+46.75x
subtract 40.50 on both sides
150=120=6.25x
subtract 120 on both sides
80=6.25x
divide by 6.25x
x=4.8
The number of months for which you would pay the same total fee to both gyms is 4.8 months.
For the given situation we need to formulate an equation.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of months be x.
Flex Gym charges a membership fee of $150 plus $40.50 per month to join the gym = 150+40.50x
A rival gym, Able Gym, charges a membership fee of $120 plus $46.75 per month = 120+46.75x
So equation is 150+40.50x = 120+46.75x
46.75x-40.50x=150-120
⇒ 6.25x=30
⇒ x=4.8
Therefore, the number of months for which you would pay the same total fee to both gyms is 4.8 months.

The mean age of teachers at Davis senior high school is 43.6 years. If a hypothesis test is performed, how should you interpret a decision that reject the null hypothesis
Answer:
The interpretation is
There is not sufficient evidence to support the claim that [tex]\mu = 43.6[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 43.6 \ years[/tex]
Generally
The null hypothesis is [tex]H_o : \mu = 43.6[/tex]
Given from the question that the null hypothesis was rejected then the conclusion will be
There is not sufficient evidence to support the claim that [tex]\mu = 43.6[/tex]
A study of adult males found their head circumferences to be Normally distributed, with a mean of 57.5 centimeters and a standard deviation of 1.5 centimeters.
Jack’s head has a circumference in the 16th percentile. How many centimeters is his head circumference? Give your answer to the nearest tenth.
Answer:
56.0 on edge
Step-by-step explanation:
Since Jack’s head has a circumference in the 16th percentile, his head circumference is 56.0 centimeters.
What is percentile?We know that In a normal distribution, a percentile is a value that has a certain percentage of observations below it.
The Z score is defined as "a numerical measurement used in statistics to determine a value's relationship to the mean (average) of a group of values, expressed in standard deviations from the mean."
Z score can be calculated as
Z = (x - μ)/σ
How to solve it?Here, mean = μ = 57.5 centimeters
standard deviation = σ = 1.5 centimeters
Let the circumference of Jack’s head = x centimeters
The percentile = 16
Z value for 16 percentile = - 0.994
So, (x - 57.5)/1.5 = - 0.994
i.e. x - 57.5 = - 0.994*1.5 = - 1.491
i.e. x = - 1.491 + 57.5 = 56.009
The nearest tenth value for 56.009 is 56.0
Then Jack's head circumference is 56.0 centimeters.

HELP WITH MATH PLEASE
1. The formula A = L x W gives the area of a rectangle R. The area of a rectangular garden is 5000sqm.
What is the garden's length in terms of width?
2. The formula for the area of a triangle is A = ½ bh, where b is the length of the base, and h is the height. Solve for b
3. The formula for an object’s final velocity is f = i – gt, where i is the object’s initial velocity,
g is acceleration due to gravity, and t is time. Solve for t.
4. Make your own question and solve it for your chosen variable:
Answer:
1. Length in terms of width is 5000/W meters
2. Solving for b gives us: [tex]b = \frac{2A}{h}[/tex]
3. Solving for t gives us: [tex]t = \frac{i-f}{g}[/tex]
4. Solving for P gives us:
[tex]W = \frac{P}{2} - L[/tex]
Step-by-step explanation:
1. The formula A = L x W gives the area of a rectangle R. The area of a rectangular garden is 5000sqm. What is the garden's length in terms of width?
Given that
[tex]A= L*W[/tex]
Also given that A = 5000 square meters.
Now,
[tex]5000 = L * W[/tex]
Dividing both sides by W
[tex]\frac{L*W}{W} = \frac{5000}{W}\\L = \frac{5000}{W}[/tex]
So,
Length in terms of width is 5000/W meters
2. The formula for the area of a triangle is A = ½ bh, where b is the length of the base, and h is the height. Solve for b
The given formula is:
[tex]A = \frac{1}{2}bh[/tex]
Solving it for b means that the we have to isolate b
So,
[tex]A = \frac{1}{2}bh\\2A = 2. \frac{1}{2}bh\\2A = bh\\\frac{2A}{h} = \frac{bh}{h}\\b = \frac{2A}{h}[/tex]
Solving for b gives us: [tex]b = \frac{2A}{h}[/tex]
3. The formula for an object’s final velocity is f = i – gt, where i is the object’s initial velocity, g is acceleration due to gravity, and t is time. Solve for t.
Given
[tex]f = i-gt\\Now\\f+gt = i\\gt = i-f\\\frac{gt}{g} = \frac{i-f}{t}\\t = \frac{i-f}{t}[/tex]
Solving for t gives us: [tex]t = \frac{i-f}{g}[/tex]
4. Own Question: The perimeter of a rectangle is given by P = 2(L+W). Solve for width.
[tex]P = 2(L+W)\\\frac{P}{2} = \frac{2(L+W)}{2}\\\frac{P}{2} = L+W\\\frac{P}{2} - L = W[/tex]
Solving for P gives us:
[tex]W = \frac{P}{2} - L[/tex]

Factor this trinomial completely.

B. (2x + 5)(6x-3)
C. (2x+3)(6x – 5)
D. (3x + 5)(4x – 3)
Answer:
Option C. (2x+3)(6x – 5) is the correct answer.
Step-by-step explanation:
Given polynomial(trinomial) is:
[tex]12x^2 + 8x - 15[/tex]
The given trinomial is quadratic. Factorization will be as follows:
Multiplying the co-efficient of x^2 and the constant results in 180. We have to make factors of 180 in such a way that their sum of difference is equal to the co-efficient of x.
The required factors are 18 and 10
So,
[tex]=12x^2+18x-10x-15\\=6x(2x+3)-5(2x+3)\\= (6x-5)(2x+3)[/tex]
Hence,
Option C. (2x+3)(6x – 5) is the correct answer.
