Answer:
$1.05
Step-by-step explanation:
The amount of money they should pay is 4.15+6.35+2*1.1+1.25 = $13.95
The change is 15-13.95=$1.05
Answer:
90
Step-by-step explanation:
$5.29 * 16.3 = $86.227
=$86.23
86.23 could be rounded up to 90
Answer:
4
Step-by-step explanation:
Gradient is the same as slope to get your answer follow this formula y2 - y1 divided x2 -x1 in this problem it will look like this
4 - (-4) /1 - (-1) =
8 / 2 =
= 4
I hope this helps!!
Answer:
360 cm cubed
Step-by-step explanation:
Use the volume formula.
V=whl
V=12 x 6 x 5
V=360
Answer:
y=12.75x and y=13x
Step-by-step explanation:
The rate of change is another name for slope. To find the slope of Relationship B, we use the formula
m = \frac{y_2-y_1}{x_2-x_1}
Using the first two points, we have
m = (50-25)/(4-2) = 25/2 = 12.5
This means that anything with a rate of change greater than 12.5 works in this problem.
The equations listed for Relationship A are in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in all of these, b = 0).
In the first equation, m = 13; in the second equation, m = 11.5; in the third equation, m = 12.75; and in the fourth equation, m = 12.25. The only ones with higher slopes than Relationship B are the first and the third one.
