The equation that represents Runner #2 is t = 8.5d where t is time (in minutes) and d is distance in miles). If
Runner #2 runs 2 miles, how many minutes will it take?
Answer:
17minutesStep-by-step explanation:
Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;
t = 8.5d
t = 8.5(2)
t = 17.0 minutes
Hence it will take the runner 17minutes to run 2 miles.
Runner #2's equation is an illustration of proportional equations
It will take runner #2 17 minutes to run 2 miles
Runner #2's equation is given as:
[tex]\mathbf{t = 8.5d}[/tex]
When runner #2 runs two miles, it means that:
d = 2
Substitute 2 for d in the given expression.
So, we have:
[tex]\mathbf{t = 8.5 \times 2}[/tex]
Multiply
[tex]\mathbf{t = 17}[/tex]
Hence, it will take runner #2 17 minutes to run 2 miles

A factory uses 1/8 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 3/4 of a barrel of raisins. How many batches of granola bars did the factory make yesterday?
Answer: 6
Step-by-step explanation:
From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.
To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
The company made 6 batches of granola bars

Ethan had his two friends over for pizza. Ethan ate 1/4 of the pizza. One of his friends ate 3/8 of the pizza and the other friend ate 1/8 of the pizza. How much of the pizza is left?
Answer:
2/8 or 1/4
Step-by-step explanation:
this is because 2/8+3/8+1/8= 0.75
0.75=3/4
1-3/4=1/4
The amount of pizza left Ethan had his two friends will be 1/4.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Ethan had his two friends over for pizza. Ethan ate 1/4 of the pizza. One of his friends ate 3/8 of the pizza and the other friend ate 1/8 of the pizza.
Then the amount of pizza left is given as,
⇒ 1 - 1/4 - 3/8 - 1/8
⇒ 8/8 - 2/8 - 3/8 - 1/8
⇒ (8 - 2 - 3 - 1) / 8
⇒ (8 - 6) / 8
⇒ 2/8
⇒ 1/4
The amount of pizza left Ethan had his two friends will be 1/4.

A 15 meter long cylinder with a diameter of 7 meters has a square prism
with a base length of 4 meters hole going all the way through the center of
it as shown in the diagram (not to scale). Find the volume of the composite
shape rounding to the nearest cubic meter.
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.
In order to find a constant rate of change, the function must be linear.

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy
Answer:
6 laptops
Step-by-step explanation:
First, find the amount spent on the textbooks:
30(116)
= 3480
Subtract this from the total amount they have to spend:
6500 - 3480
= 3020
Divide this amount by 439 to find how many laptops they can buy:
3020/439
= 6.8
Round down to 6 since you can only have full laptops:
= 6
So, they can buy 6 laptops
