Dominic rides his bike at a rate of 4 min per mile

taurus [48]

Answer:

Dominic can ride a mile every 4 minutes so if total miles is represented by m, then the solution for how many minutes he's riding for a specific amount of time would be 4m (4 x m). For example, if you want to find out how many minutes it would take to ride 1 mile, substitute m for 1. It would be 4 x 1 = 4 so it takes a total of 4 minutes. If you want to find out how many minutes it took to ride 6 miles, substitute m for 6. It would be 4 x 6 = 24 so it would take a total of 24 minutes to ride 6 miles. If you want to find out how many minutes it took to ride 12 miles, substitute m for 12. It would be 4 x 12 = 48 so it would take a total of 48 minutes to ride 12 miles. I think you gave a lack of information so your question is incomplete but I hope this is applicable and helps anyways!

How many times greater is the value of 3 in 300 than the value of the 3 in 30

Vikki [24]

Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30.

The average (arithmetic mean) of five different positive integers is 30. What is the greatest possible value of one of these int

geniusboy [140]

Answer:

The Greatest possible value of one of the integer is 140.

Step-by-step explanation:

Given: The average (arithmetic mean) of five different positive integers is 30.

To find: What is the greatest possible value of one of these integers?

Explanation: we are given that the arithmetic mean of five positive integer

is 30.

Let the five positive integers are A,B,C,D,E

The arithmetic mean :

$\frac{A+B+C+D+E}{5}$ =30.

On multiplying both side by 5.

A+B+C+D+E =150.

The least values of A ,B,C and D can be 1 ,2,3,4.

Then : 1 +2+3+4+E =150

On simplification 10+E =150

On subtraction both side by 10 we get

E = 140 .

Therefore, the Greatest possible value of one of the integer is 140.

Question

maria [59]

Answer:

y = m x + b equation of a straight line

m m' = -1 condition for perpendicular lines

If y = 4 x - 7 then m = 4 so m' = -.25

Y = -.25 X + A we need to find A

A = Y + .25 * 8 = 2 + 2 = 4

Y = -.25 X + 4

Check:

2 = -.25 * 8 + 4 = -2 + 4 = 2
