The distance traveled by a car at a constant rate is proportional to the time spent driving. In the equation d = 45t, d represents the distance (in miles) and t represents the time (in hours).
A. What is the constant of proportionality? _____ miles per hour
B. How far will a car travel in 3 hours? _______ miles
Answer: A. 45 miles per hour
B. 135 miles
Step-by-step explanation:
Given: The distance traveled by a car at a constant rate is proportional to the time spent driving.
In the equation [tex]d=45t[/tex], d represents the distance (in miles) and t represents the time (in hours).
[tex]\Rightarrow\frac{d}{t}=45\text{ miles per hour}[/tex]
⇒ The constant of proportionality=45 miles per hour.
Also, the distance traveled by car in 1 hour=45 miles
⇒ The distance traveled by car in 3 hours=[tex]3\times45=135\text{ miles}[/tex]
∴ A car will travel 135 hours in 3 hours.

The area of a rectangle city park is 25/54 square miles.The park is 5/9 mile. What is the width in miles of the park ?
To find the width of the park, divide the area (25 / 54 square miles) by the length (5 / 9 miles), resulting in a width of
5 / 6 miles.
The question asks to find the width in miles of a rectangular city park whose area is 25 / 54 square miles and whose length is 5 / 9 miles. To find the width, we can divide the area by the length:
Width = Area / Length
Width = (25 / 54) [tex]\div[/tex] (5 / 9)
To divide fractions, we multiply by the reciprocal of the divisor:
Width = (25 / 54) X (9 / 5)
Width = (25 X 9) [tex]\div[/tex] (54 X 5)
Width = (225) [tex]\div[/tex] (270)
Then we reduce the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 45:
Width = (225 / 45) [tex]\div[/tex] (270 / 45)
Width = 5 / 6
Therefore, the width of the park is 5/6 miles.

Tristan has 45 apples and 20 pears tgat he is putting into gift baskets.Each basket will have the same number of apples and pears.What is the greatest number of baskets Tristan can make with no fruit left over? Explain
Answer: 5
Step-by-step explanation:
Given : Tristan has 45 apples and 20 pears that he is putting into gift baskets.
Each basket will have the same number of apples and pears.
To find the greatest number of baskets Tristan can make with no fruit left over, we find the greatest common factor if 45 and 20.
For that first we write the prime factorization of 45 and 20 :-
[tex]45=3\times3\times5\\\\20=2\times2\times5[/tex]
Greatest common factor of 45 and 20 (GCF) = 5
Hence , the greatest number of baskets Tristan can make with no fruit left over =5

Which expression is equivalent to -3 (2m- 1) -n
The expression -6m-n+3 is equivalent to our given expression.
To find the equivalent expression for -3(2m - 1) - n, distribute the -3 to 2m and -1, and then combine like terms:
[tex]\(-3(2m - 1) - n\)[/tex]
[tex]\(-6m + 3 + n\)[/tex]
So, the correct answer is option D) -6m - n + 3.
Complete question:
Which expression is equivalent to -3(2m - 1) - n?
A) 6m - n - 3
B) 6m - n + 3
C) -6m - n - 3
D) -6m - n + 3
Both parts A and b have three digits multipliers. Why are there three partial products in part a and only two partial products in part b
The number of partial products in multiplication is determined by the number of digits in the multiplier.
Explanation:In multiplication, the number of partial products is determined by the number of digits in the multiplier. In part a, there are three digits in the multiplier, so there are three partial products. Each partial product represents the product of a digit in the multiplier and the multiplicand. In part b, there are only two digits in the multiplier, so there are only two partial products.

Suppose you are adding 43 and 28. Will you regroup? Why ?
Answer:
Yes, we have to regroup. Why because of place value chart, we have to regroup.
Step-by-step explanation:
When we add, we have to add the numbers according to the place value chart.
Tens ones
4 3
2 8
-----------------
7 1
When we add ones place, we get 3 + 8 = 11, it is a two digits number, so place ones place (1) and carry over the tens (1) to the tens place.
Already, we have 4 and 2 in the tens place, another 1 tens adds to tens place.
4 + 2 + 1 = 7
Hope this will helpful.

a railroad car container can hold 42,000 pounds. Mr.Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers can be shipped in the container? Explain
Mr. Evans can ship approximately 70 freezers in the container.
To determine how many freezers can be shipped in the container, we first need to calculate the total weight of the ovens and then subtract it from the maximum weight the container can hold.
Given:
- Maximum weight the container can hold = 42,000 pounds
- Number of ovens = 90
- Weight of each freezer = 600 pounds
First, we need to calculate the total weight of the ovens:
Total weight of ovens = Number of ovens × Weight of each oven
Total weight of ovens = 90 ovens × 0 pounds = 0 pounds
Now, we subtract the total weight of the ovens from the maximum weight the container can hold to find the remaining weight for the freezers:
Remaining weight for freezers = Maximum weight of container - Total weight of ovens
Remaining weight for freezers = 42,000 pounds - 0 pounds
Remaining weight for freezers = 42,000 pounds
Now, we need to find out how many freezers can be shipped in the container. Since each freezer weighs 600 pounds, we divide the remaining weight for freezers by the weight of each freezer:
Number of freezers = Remaining weight for freezers / Weight of each freezer
Number of freezers = 42,000 pounds / 600 pounds
Number of freezers ≈ 70
So, Mr. Evans can ship approximately 70 freezers in the container.
What best describes the expression y over 3?
3 more than some number
Some number times 3
Some number divided by 3
3 less than some number
Answer:
The answer would be "Some number divided by 3"
Step-by-step explanation:
y = some number.
3 = 3
When an equation is shown in a fraction and you're using any terms that may be used to represent "some number," such as y, x, etc; it usually means to divide the two numbers in the fraction.
Sorry if that didn't make sense, I'm only in 7th grade and I'm very bad at explaining haha

3x+15y=7. Solve for Y
To solve the equation 3x + 15y = 7 for y, subtract 3x from both sides and then divide by 15. This results in y = (7 - 3x) / 15.
Explanation:To solve this equation, 3x + 15y = 7, for y, you need to isolate y. You can do this by first subtracting 3x from both sides of the equation, which leaves you with 15y = 7 - 3x. Then, to solve for y, divide both sides of the equation by 15, which results in y = (7 - 3x) / 15.Learn more about Solving Equations here:https://brainly.com/question/18322830
