John rode his bicycle to school and back home. The distance from his home to school is 1.30 miles. What is the approximate number of kilometers that John rode? (1.00 kilometers = 0.62 miles)

Answer:

This seems to be a linear relationship:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

We know that 3 workers can complete the job in  4 days.

Then if we define W as the rate at which a single worker can complete the work, we have the ordered pair (3 workes, 4 days)

And we also know that 6 workers can finish the job in 3.05 days, then we also have the ordered pair (6 workers, 3.05 days)

Then using these two, we can find the slope of the line:

a = (3.05 days - 4 days)/(6 workers - 3 workers) = -0.35 days/worker.

Then we have the equation:

y = (-0.35 days/worker)*x + b

Where:

y represents the time to complete the job

x represents the number of workers.

b is the y-intercept, to find the value, we could just replace one of the points in the equation, for example with the point (3 workes, 4 days) we need to replace x by 3 workers, and y by 4 days:

4 days = (-0.35 days/worker)*3 workers + b

4 days = -1.4 days + b

4 days + 1.4 days = 5.4 days  = b

then the equation is:

y = (-0.35 days/workers)*x + 5.4 days.

Now we can find the number of days needed for 5 workers to finish the job, we just need to replace x by 5 workers:

y = (-0.35 days/workers)*5 workers + 5.4 days

y = 3.65 days.

Answer:

Employees who play musical instruments = 6

Step-by-step explanation:

Given that:

Ratio of employees who play musical instruments to employees who play sports is 3 : 20

Number of employees who play sports = 40

Let,

x be the number of employees who play musical instruments.

Ratio = x : 40

As the relationship is proportional,

3 : 20 :: x : 40

Product of mean = Product of extreme

20x = 120

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{120}{20}\\x=6[/tex]

Hence,

Employees who play musical instruments = 6

Answer:

120 Minutes

Step-by-step explanation:

24 minutes / 2 miles = 12 minutes / 1 mile

12 minutes / 1 miles = x minutes / 10 miles

Cross multiply

12*10/1 = x

120 / 1 = x

x = 120

$20.85

Step-by-step explanation:

The amount of one cost in 1983, to the nearest cent is to be considered as the option a. $20.85.

Since

The CPI is currently 153.

And, there a coffee maker costs $31.90 today.

So the one cost should be like

[tex]= 31.90 \div 153[/tex]

= 20.85%

Answer:

6/7

Step-by-step explanation:

because there are 28 properties in all

4 of them are railroads

but we're not looking for the probability of selecting a railroad, which would be 4/28 or 1/7, but for not selecting a railroad

and 24 of them are not railroads

So the probability of not selecting a railroad is 24/28, which simplified/reduced is 6/7

Step-by-step explanation:

Answer:

y = (x + 4)²

Step-by-step explanation:

Given equation is,

y = x²+ 8x + 16

By using identity (a + b)² = a² + 2ab + b²

y = x² + 2(4)(x) + 4²

Here a = x and b = 4

y = (x + 4)²  

Therefore, factored form of the given equation is y = (x + 4)²

Answer:

x<6

Step-by-step explanation:

b. x≤6

so the empty circle means it's (in this case) less than or equal to 6. the < looks like an L, so think, L is for Less than. Also, the < looks like part of <-, so that's the way the arrow points! hope this helps, good luck!
