6
of an hour stretching before they start their practice sets. If each practice set takes
1
3
of an hour, how many sets can Javier do before practice is over?
Answer:
4 sets
Step-by-step explanation:
The number of sets can Javier do before practice is over is 4.
Given that, Javier's swim practice is 1 1/2 hours long. The team spends 1/6 of an hour stretching before they start their practice sets. If each practice set takes 1/ 3 of an hour.
We need to find how many sets can Javier do before practice is over.
How to add and subtract the fractions?The steps for adding and subtracting fractions are as follows:
Step 1: Make denominators the same
Step 2: Add/Subtract the numerators (keeping the denominator as same)
Step 3: Simplify the fraction
We can write 1 1/2 as 3/2
Now, the number of hours left after stretching = 3/2 - 1/6
=9/6 - 1/6
=8/6
=4/3
So, number of sets = 4/3 ÷ 1/3
= 4/3 × 3/1
=4
Therefore, the number of sets can Javier do before practice is over is 4.

A local hamburger shop sold a combined total of 615 hamburgers and cheeseburgers on Sunday. There were 65 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
The hamburgers and cheeseburgers sold on Sunday will be 275 and 340, respectively.
Given that:
H + C = 615 ...(1)
C = H + 65 ...(2)
From equations (1) and (2), then we have
H + H + 65 = 615
2H = 550
H = 275
Then the value of cheeseburgers (C) is calculated as,
C = 275 + 65
C = 340
The hamburgers and cheeseburgers sold on Sunday will be 275 and 340, respectively.

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
From the graph, the line is passing through (0, 0) and (3, 4). Then the equation of the line is given as,
(y - 0) = [(4 - 0) / (3 - 0)](x - 0)
Simplify the equation, then we have
(y - 0) = [(4 - 0) / (3 - 0)](x - 0)
y = (4/3)x

The number of square feet per house is normally distributed with a population standard deviation of 154 square feet and an unknown population mean. If a random sample of 16 houses is taken and results in a sample mean of 1550 square feet, find a 80% confidence interval for the population mean. Round your answer to TWO decimal places.
Answer: (1500.66,1599.34)
Step-by-step explanation:
Confidence interval for population mean:
[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex]
,where [tex]\overline{x}[/tex] = Sample mean , n= Sample size, z* = critical two tailed z-value , [tex]\sigma[/tex] = population standard deviation.
As per given , we have
n= 16
[tex]\sigma = 154[/tex] square feet
[tex]\overline{x}= 1550[/tex] square feet
[tex]\alpha= 1-0.80 = 0.20[/tex]
Critical z-value = [tex]z_{\alpha/2}=z_{0.2/2}=z_{0.1}=1.2815[/tex]
Confidence interval for population mean:
[tex]1550\pm (1.2815)\dfrac{154}{\sqrt{16}}\\\\ = 1550\pm (1.2815)\dfrac{154}{4}\\\\= 1550\pm 49.33775\\\\ =(1550-49.33775,\ 1550+49.33775)\\\\\approx (1500.66,\ 1599.34)[/tex]

Which represents the inverse of the function f(x) = 4x?
A. h(x) = x+4
B. h(x) = x-4
C. h(x) = 3/4x
D. h(x) = 1/4x
Answer: D
Step-by-step explanation:
To find the inverse, you switch x with y and y with x. Then, you solve for y.
y=4x [switch y with x and x with y]
x=4y [divide both sides by 4]
y=x/4
Now, we know the answer is D.

7 x (3 x 5) = (7 x 3) x 5
7 x (3 x 5) = 7 x (5 x 3)
7 x 1/7 = 1
When a number x is divided by 24 the remainder is 23 and when it is divided by 36 the remainder is 35. Find the least number that x can be.
Answer:
7 is the answer. If a number can be divided by 36 then it can also be divided by 12 which is 3*12 therefor the remainder will be 19-12 which is 7. When 19 is divided by 36, the remainder is 19 and so 19 must be a number. When 19 is divided by 12 the remainder is 7.

Find the slope of a parallel line -10+x-2y=0
Answer: 1/2
Step-by-step explanation:
First convert the equation into slope-intercept form.
-10 + x -2y = 0
+10 +10
x - 2y = 10
-x -x
-2y = 10 - x Divide both sides by -2
y = 1/2x - 5
In this case the slope is 1/2 and the slopes parallel lines are the same but they must have different y intercepts. Meaning that the slope of the other line will be 1/2.
