Answer:if they work together, it will take them 0.5 hours or 30 minutes
Step-by-step explanation:
jake can complete a job in 1 hour 30 minutes or 1.5 hours. This means that his unit rate is 1/1.5
his friend Harry can complete the same job in half the time. This means that Harry can complete the same job in 0.75 hours. His unit rate of working would be 1/0.75.
Since both of them work simultaneously at their individual rates, then, Their unit rates are additive. Assuming by working together, it took them t hours to finish the work. This means that their combined unit rate would be 1/t. Therefore,
1/1.5 + 1/0.75 = 1/t
1/t = 2
2t = 1
t = 1/2 = 0.5 hours or 30 minutes
Check the picture below.
so, if we get the whole area of the figure, which will be the combined areas of those three rectangles, and if we get the area of the triangle, and then subtract that area from of the triangle from the whole figure's area, we're in effect making a whole in the total area, and what's leftover is the shaded area.

Answer:
B.It is linear 180=3x2+24x+36
Step-by-step explanation:
Answer:
Equation of the line is y = x + 1
Standard Form: x - y = 1
Step-by-step explanation:
Ax + By = C
y = x + 1
-x + y = 1 ("A" must be positive)
x - y = -1
