Answer:
13.92$
Step-by-step explanation:
13.26 times .05 (sales tax)
.66 + 13.26 = 13.92
Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
The sum of angles in a triangle is 180 degrees.
This implies that:
m<A+138=180
m<A=180-138=42
Now we use the sine rule to find AC=b
This implies that:
Answer:
The perfect square number between 40 and 50 is 49 which is a square of 7.
Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
