James runs 8 laps in 14 minutes. How many laps can he run in one hour and ten minutes?
Answer: Don't come at me if I'm wrong, but I believe it's 40 laps.
Step-by-step explanation:
First, you need to figure out how many laps James runs in 1 minute and you can do this by dividing the number of laps and minutes (8 laps/14 minutes). This should give you 4/7 laps/minute.
Next, you figure out how many minutes 1 hour and 10 minutes is (just to make things easier) 1 hour and 10 minutes = 70 minutes
Then, you multiple 4/7 and 70 and you get 40 laps.
Answer:
40 laps
Step-by-step explanation:
I just put this into a proportion
so basically i just did 8/14 = ?/70
Then i just worked it like any other problem
8 x 70 then divide 14 and i got 40.
so James ran 40 laps in one hour and tens minutes
NOTE that i turned one hour and ten minutes into minutes

Anna wants to bake 2 1/2 dozen cookies for a party. However, the recipe she has only makes a dozen cookies. If the original recipe calls for 1 1/4 cups of sugar, how many cups of sugar does she need to make the cookies for her party? Express your answer as a mixed number.
Given :
Sugar required for 2 1/2 = 5/2 dozen of cookies is 1 1/4 = 5/4 cups.
To Find :
How many cups of sugar does she need to make the cookies for her party.
Solution :
Let, cups of sugar required to make cookies for her party is x.
So,
[tex]x = \dfrac{\dfrac{5}{4}}{\dfrac{5}{2}}\\\\\\x = \dfrac{1}{2}[/tex]
Therefore, 1/2 cup of cookies is required to make 1 dozen cookies.
Hence, this is the required solution.
Answer: 25/8
Step-by-step explanation:
We would first turn 2 1/2 and 1 1/4 into an improper fraction.
That leaves us with 5/2 and 5/4.
Then, because she needs to make 5/2 dozen cookies and needs 5/4 cups of sugar for every batch, we would multiply 5/2 and 5/4 together.
Therefore x, or the amount of sugar she needs, is 25/8

To add or subtract fractions, what must you have?
Answer:
You need a common denominator.
Step-by-step explanation:
3/4+2/3
9/12+8/12
Answer:
Equal denominators/common denominators
Step-by-step explanation:
You need to have equal denominators. If you do not, then you have to multiply the denominators against each other as well as multiplying the same number to the numerator. If a number is a factor of one of the numbers then multiply the number by its other factor so as to get the same number.
Ex. 1
First one explained:
2/3 + 4/5
1/3 * 5/5 = 5/15
2/5 * 3/3 = 6/15
5/15 + 6/15 = 11/15
Common denominator = 15
Ex. 2
Second one explained:
2/8 + 1/4
2/8 + 1/4*2/2 = 2/8 + 2/8
= 4/8
Common Denominator = 8Hope this helped,

For which equation is a = 4 not the solution?
9 a = 36
5 a = 54
8 a = 32
6 a = 24
9x4=36 X
8x4=32 X
6x4=24 X
5x4=20, not 54.
So 5xA=54 is the correct answer

Mr Roman drove from his hometown to another city. He used 12 1/4 gallons of gas for 318 1/2 mile trip. On average, how many miles did Mr. Roman travel per gallon of gas
Answer: 26 miles
Step-by-step explanation:
Gallons of gas used = 12 1/4 = 12.25
Distance of the trip = 318 1/2 = 318.5 miles
The miles that Mr. Roman travel per gallon of gas will be:
= Distance of the trip / Gallons of gas used
= 318.5/12.25
= 26 miles
Mr Roman travelled 26 miles per gallon of gas

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
from the diagram, we get,
m∠TUX = 122°
∴m∠VUS = 122°
(vertically opposite angles are equal)
Hence, The solution is, m∠VUS = 122.

Which option correctly shows how this formula can be rearranged to isolate x^2?
Options in picture.
Answer:
A
Step-by-step explanation:
We have:
[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:
[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]
The right side will cancel. This will leave:
[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]
Now, we can subtract x₁ from both sides. So:
[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]
Finally, we will multiply both sides by -1. So:
[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]
Hence, our answer is A.
