Relationship between distance and time is A. d = 0.12m

Step-by-step explanation:

For an object moving in uniform motion (=constant velocity), the relationship between distance covered and time taken is given by

d=vt

where

d is the distance

v is the velocity

t is the time

Therefore, in order to find the relationship between distance and time, we have to find the velocity of the train.

This can be done by using the data of the table: in fact, the velocity is the ratio between the distance covered and the time taken to cover that distance.

Therefore, if we take for instance the last point of the table:

d = 2.4 miles (distance covered)

t = 20 minutes (time taken)

So the velocity is

v=\frac{d}{t}=\frac{2.4}{20}=0.12 mi/min

And therefore, the relationship between distance and time is

d=0.12 m

(where m is the time in minutes)

ANSWER IF YOU LOVE YOUR LORD!!!! Which graph represents the solution to: 2k+8<5k-1?
Leviafan [203]

Answer:

Third graph

Step-by-step explanation:

First, find the solution to the equation of inequality given.

2k + 8 < 5k - 1

Subtract 5k from both sides

2k + 8 - 5k < 5k - 1 - 5k

-3k + 8 < -1

Subtract 8 from both sides

-3k + 8 - 8 < -1 - 8

-3k < -9

Divide both sides by -3. (Note: < will change to > when dividing both sides with negative number)

\frac{-3k}{-3} > \frac{-9}{-3}

k > 3

The graph that will represent this solution will show that all values of k are greater than 3. 3 is not included as a solution. The "o" on top of the 3 on the number line won't be shaded to indicate that 3 is not included. And also, the arrow will point from 3 towards our right.

Therefore, the 3rd graph is the answer.

Afina-wow [57]

Answer:

(a - b)(5x - 2y)

Step-by-step explanation:

5x(a - b) – 2y(a - b) =

The factors in parentheses (shown in bold) are a common factor.

Factor (a - b) out from both terms.

= (a - b)(5x - 2y)

mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500
SOVA2 [1]

Answer:

3300

Step-by-step explanation:

Formula

Gross Salary = Basic + Commission

Givens

Basic = 3000

% = 12%

Solution

Gross = 3000 + 12/100 * 2500

Gross = 3000 + 30000/100

Gross = 3000 + 300

Gross = 3300
