Joseph ran LaTeX: 2\frac{3}{4}2 3 4 miles in LaTeX: \frac{2}{5}2 5 of an hour. How fast did Lin run in 1 hour? (try to leave your answer in a fraction) Nathaniel ran LaTeX: 8\frac{2}{3}8 2 3 miles in LaTeX: \frac{4}{3}4 3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction) Who ran the fastest, Nathaniel or Joseph?
Answer:
Nathaniel ran fastest
Step-by-step explanation:
For Joseph
Joseph ran 2 3/4 miles 2 /5 of an hour.
Speed = Distance/Time
Speed = 2 3/4 miles ÷ 2/5 hour
= 11/4 ÷ 2/5
= 11/4 × 5/2
= 55/8 miles/hour or 6.875 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
2/5 hour = 55/8 miles per hour
1 hour = x
Cross Multiply
x = 55/8 ÷ 2/5
x = 55/8 × 5/2
x = 275/16 miles per hour
x = 17 3/16 miles per hour
Nathaniel ran LaTeX: 8 2/3 miles in 4 /3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction)
Speed = Distance/Time
Speed = 8 2/3 miles ÷ 4/3hour
= 26/3 ÷ 4/3
= 26/3 × 3/4
= 26/4 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
4/3 hour = 26/4miles per hour
1 hour = x
Cross Multiply
x = 26/4 ÷ 4/3
x = 26/4 × 3/4
x = 78/16 miles per hour
x = 4 14/16 miles per hour
= 4 7/8 miles per hour
Who ran the fastest, Nathaniel or Joseph?
Hence, from the calculation above, Nathaniel ran fastest

A bakery used 25% more butter this month than last month. If the bakery used 240 kilograms of butter last month, how much did it use this month?
Round your answer to the nearest whole number.
Answer:
300kg
Step-by-step explanation:
x = kilograms of butter used this month
A bakery used 25% more butter this month than last month.
x = 240 * 1.25
x = 300
Answer:
300kg
Step-by-step explanation:
So if the bakery used 240kg
60 is 25%
240 + 60 = 300kg this month
So, the total butter used this month is 300 kilograms
What is the correct answer for both?
Answer:
15) C (3, -4)
16) B (-1, 1)
Step-by-step explanation:
8x + 6y = 0
8x + 2y = 16
8x + 2y = 16
8x = 16 - 2y
x = 2 - 1/4y
8x + 6y = 0
8(2 - 1/4y) + 6y = 0
16 - 2y + 6y = 0
16 + 4y = 0
4y = -16
y = -4
8x + 2y = 16
8x + 2(-4) = 16
8x - 8 = 16
8x = 24
x = 3
________________
-20x - 3y = 17
10x - 4y = -14
-20x - 3y = 17
-20x = 17 + 3y
x = -17/20 - 3/20y
10x - 4y = -14
10(-17/20 - 3/20y) - 4y = -14
-8.5 - 1.5y - 4y = -14
-8.5 - 5.5y = -14
-5.5y = -5.5
y = 1
-20x - 3y = 17
-20x - 3(1) = 17
-20x - 3 = 17
-20x = 20
x = -1

Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.
Answer:
its 1/3 of the volume of a cyinder with the same base
Step-by-step explanation:
a pyramid has the same policy with prisms of the same base
Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
What is volume?
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.
The volume of the cone with radius r units and height h units now can be written as,
Volume of the cone = (1/3) × π × r² × h units³
The volume of the cylinder with a radius of r units and the height of h units now can be written as,
Volume of the Cylinder = π × r² × h units³
Taking the ratio of the volume of the cone and the volume of the cylinder,
Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³
Volume of the cone/Volume of the cylinder = 1/3
Volume of the cylinder = 3 × Volume of the cone
Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

a. 8

What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.
