Solve:-
7.8 × 0.5 = How far Erica jogged
7.8 × 0.5 = 3.9
3.9 Miles
So, if Marsha jogged 7.8 miles, and Erica jogged 0.5 times as far, as Marsha, Erica jogged 3.9 Miles.
Hope I helped ya!! xD
Answer:
y = 2x + 4
Step-by-step explanation:
So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.
Answer:
y= ⅓x +2
Step-by-step explanation:
Since the graph is a linear graph, let's use the slope-intercept form to find its equation.
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.
The y-intercept is the point at which the graph cuts through the y-axis. In this case, the y-intercept is 2.
Thus, y= mx +2.
Let's find the slope of the graph.
First, identify 2 pairs of coordinates from the graph:
(0, 2) and (3, 3)
Next, substitute these coordinates into the slope formula below:

slope


Thus, the equation of the graph is y= ⅓x +2.
If the dimensions are tripled then the surface area will increase by a factor of 3^2
That is by 9.
The volume will increase by a factor 3*3 (= 27).
