A car is traveling at a speed of 75 km/h. compute the speed of the car in m/s.

MaRussiya [10]

1 km = 1000 m
1 h = 3600 s

75 km/h
75 *1000 m / 3600 s
75 * 5 m / 18 s
25 * 5 m / 6 s
125 m / 6 s
20.8 m/s

answer is c.

Which describes a cost method of solving systems of equations by using addition, subtraction, multiplication, or division to get

uysha [10]

Answer:

Step-by-step explanation:

eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.

The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.

Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .

If you have $65 to spend at a concert and you already spend $32.25 on a ticket and fee. What is the maximum number of shirts he

Marrrta [24]

The maximum number of shirts I can buy is 2.

14.50 x 2 = 29
14.50 x 3 = 43.5

Two shirts cost 29 dollars, and 3 shirts cost 43.5 dollars. Since $43.5 is higher than the money I currently have, I can only buy 2 shirts.

Drag the correct graph of each equation into the space next to that equation to show how the output y-values change with changes

Jlenok [28]

Answer:

see the explanation and the attached figure

Step-by-step explanation:

Part 1) Linear

we have

$y=x+3$

This is the equation of the line in slope intercept form

The slope is positive and equal to m=1

The y-intercept is b=3

As the value of x increases the value of y increases too

As the value of x decreases the value of y decreases too

therefore

The graph in the attached figure

Part 2) Quadratic function

we have

$y=3x^2$

This is a vertical parabola open upward with the vertex at origin

As the value of x increases the value of y increases too

As the value of x decreases the value of y increases

therefore

The graph in the attached figure

Part 3) Exponential function

we have

$y=3^x$

This is a exponential growth function

As the value of x increases the value of y increases too

As the value of x decreases the value of y decreases too

The initial value or y-intercept is 3

therefore

The graph in the attached figure
