A motorcycle traveling at 70 miles per hour overtakes a car traveling at 40 miles per hour that had a three-hour head start. How far from the starting point are the two vehicles

Answers

A motorcycle traveling at 70 miles per hour overtakes a car traveling at 40 miles per hour that had a three-hour head start. How far from the starting point are the two vehicles.

----------------------

The car is 120 miles away when the motorcycle starts.

The bike gains on the car at 30 mph (70-40).

It takes 4 hours for the bike to close the gap (120/30).

In 4 hours, the bike and the car are 280 miles from the starting point.

---------

4*70 = 280

7*40 = 280

Since Distance = Speed x Time, and in this case, the distances are equal, we, therefore, have: 70T = 40(T + 3)

70T = 40T + 120

30T = 120

T=4, which makes the distance that both vehicles traveled, highlight_green280miles, calculated as (70 * 4), or (40 * 7).

It also means that the motorcycle took 4 hours to travel 280 miles, and the car took 3 hours more, or 7 hours to travel the same distance.

Answer:

The equation representing the proportional relationship between j and m is m = 3j/4 .

Step-by-step explanation:

Writing an Equation to Represent a Proportional Relationship

What is proportional relationship?

A proportional relationship between two quantities is when the two quantities vary directly with one and other. Meaning if one item is doubled, the other item is also doubled.

Going back to the given problem above, we have the table showing the proportional relationship between j and m.

j | 4 | 12 | 20 |

m | 3 | 9 | 15 |

Solution:

Step #1

The proportional relationship can be written as:

m/j = ¾ = ‌9⁄12‌ = ‌15⁄20‌ = ¾

Step #2

So, the equation representing this proportional relationship is:

m = ¾ × j/1 = 3j/4

Final Answer:

The equation representing the proportional relationship between j and m is m = 3j/4 .

Match each formula on the left with an equivalent formula on the right.
W = X-Y

W = 4 - Y
W = XY

X =W₁ + ½
X = Z(W + Y)
X = WZ+Y
X = // +Y

Answers

The formulas and the equivalent formulas are

W = X - Y                                    X = W +Y

W = X/Z - Y                                 X = Z(W + Y)

W = (X - Y)/Z                               X = WZ+Y

W = XY                                       X =W/Y

How to match the formulas?

To do this, we simply make X the subject of the formula in expressions on the left.

So, we have:

W = X - Y

This gives

X = W + Y

W = X/Z - Y

This gives

X/Z = W + Y

X = Z(W + Y)

W = (X - Y)/Z

This gives

X - Y = WZ

X = WZ + Y

W = XY

This gives

X =W/Y

Let $m$ be a positive integer such that $m$ has exactly 5 positive divisors. How many distinct prime factors does $m$ have

Answers

If m has exactly 5 positive divisors then there can only be one prime factor.

According to statement

m has exactly 5 positive divisors AND

Let A^p,B^q,.... are the possible factors of integer m then

assume that p and q ≥ 1.

then the number of possible divisors cannot be 5 because there are no two integers  p, q ≥ 1, such that (p +1)(q + 1) = 5

So, If m has exactly 5 positive divisors then there can only be one prime factor.

According to the table, how many hours of training would you need to have a
monthly pay of $1500?

Answers

Using a linear function, it is found that you would need roughly 24 hours of training to have a monthly pay of $1500.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Looking at the table, the pay increases $200 each 10 hours of work, hence the slope is:

m = 200/10 = 20

Then:

y = 20x + b

When x = 10, y = 1220, hence:

y = 20x + b

1220 = 20(10) + b

b = 1020.

Then the pay for x hours of training is:

y = 20x + 1020.

For a pay of $1500, we have that:

y = 20x + 1020.

1500 = 20x + 1020.

20x = 480

x = 24

You would need roughly 24 hours of training to have a monthly pay of $1500.

The linear equation that best fits the data is: y = 10x + 15.

How to Write the Linear Equation of a Data?

First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.

Using two points on the graph, (1, 25) and (2, 35), find the slope (m):

Slope (m) = (35 - 25)/(2 - 1)

Slope (m) = 10/1

Slope (m) = 10

Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b

25 = 10(1) + b

25 - 10 = b

b = 15

Substitute m = 10 and b = 15 into y = mx + b
