Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Answer:
A. It increased both her intensity and her workout time.
Step-by-step explanation:
A. It increased both her intensity and her workout time.
B. It decreased her intensity but increased her workout time.
C. It increased her intensity but decreased her workout time.
D. It decreased both her intensity and work out time
Last week = 4 miles per day
This week = 5 miles per day
Intensity refers to how hard one exercises.
Workout time refers to how long one exercises the body.
By adding a mile, she has increased how hard she exercises her body (intensity))
And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

The length of a rectangle is 16 units more than it's with. The area of the rectangle can be expressed as x^4 - 64.
Answer:
[tex]Width = x^2 - 8[/tex]
Step-by-step explanation:
Given
[tex]L = 16 + W[/tex]
[tex]Area = x^4 - 64[/tex]
Required
An expression for the width
We have:
[tex]Area = x^4 - 64[/tex]
Express as difference of two squares:
[tex]Area = (x^2 + 8)(x^2 - 8)[/tex]
For all acceptable values of x,
[tex]x^2 + 8>x^2 - 8[/tex]
So:
[tex]Length = x^2 + 8[/tex]
[tex]Width = x^2 - 8[/tex]
The diameter of his friend's similar wand is 4.5 millimeters shorter than the diameter of Arun's wand. How much wire did his friend need to make the circular part of his wand? Use 3.14 for T. Round to the nearest hundredth.
Answer:
15.9 mm²
Step-by-step explanation:
We solve using Area of the circle formula
Area of a circle = πr²
Diameter of his friend's wand = 4.5mm
Radius = 4.5mm/2
= 2.25 mm
How much wire did his friend need to make the circular part of his wand? Use 3.14 for π
= 3.14 × (2.25mm)²
= 15.89625 mm²
Approximately = 15.9 mm²
solve for the unknown value
Answer:

Step-by-step explanation:
180-61-42
Answer:
x = 77°
Step-by-step explanation:
the total among these angles are 180° so add 61 + 42 which equals 103 then subtract it from the total
180° - 103° = 77°
x = 77°

Roll one fair, six-sided die, numbered 1 through 6. Let A be the event you will roll an even number.
Answer:
P(A) = 1/2
Step-by-step explanation:
The question seems incomplete, I assume that we want to find the probability of event A.
Here we have a fair six-sided dice, so each one of the six numbers has exactly the same probability of being rolled.
Such that the possible outcomes of rolling the dice is:
{1, 2, 3, 4, 5, 6}
Now we define event A as rolling an even number.
The possible outcomes such that the event A is true are the even numbers:
{2, 4, 6}
So we have 3 outcomes out of 6.
Then the probability of rolling an even numbers, is just the quotient between the number of outcomes of even numbers (3) and the total number of outcomes (6).
Then:
P(A) = 3/6 = 1/2 = 0.5

A student was trying to find the solution to a system of equations, but they were incorrect. Their explanation is shown below.
3x +4y = 10
3x + 4y =2
There are infinite solutions. When I subtract the equations, I get 0x + 0y = 8, so I know that there are infinite solutions to this system of equations.
Explain the mistake that the student made:
Answer:
no solution
Step-by-step explanation:
if you subtract the equations then you get 0 = 8 and this can never be true; therefore there are no solution
Sarah completes 1/6 of a project in 1/4 of an hour at this rate how much of the project does Sarah complete per hour? Sarah completes blank of the project per hour.
Answer:
2/3
Step-by-step explanation:
Time it would take Sarah to complete the work in one hour = work completed in 1/4 hours x 4
We are multiplying by 4 because there are 4, 1/4 in an hour
1/4 + 1/4 + 1/4 + 1/4 = 1 hour
[tex]\frac{1}{6}[/tex] × 4 = [tex]\frac{4}{6}[/tex]
To transform to the simplest form. divide both the numerator and the denominator by 2

What is the solution to the equation 6y –2(y + 1) = 3(y – 2) + 6?
y = –10
y = –2
y = 2
y = 6
Answer:
y = 2
Step-by-step explanation:
6y - 2(y + 1) = 3(y - 2) + 6
6y - 2y - 2 = 3y - 6 + 6
6y - 2y - 2 = 3y
4y - 2 = 3y
4y - 2 + 2 = 3y + 2
4y = 3y + 2
4y - 3y = 3y - 3y + 2
y = 2

HELP WITH THIS MATH QUESTION
Answer:
3
Step-by-step explanation:
The solution to a system of equations is the intersection point of two or more lines on a graph.
In this case, we see that at (1, 3)
Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.
We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.
So the first answer, A, is correct.
Hope this helps!
