Answer:
C. 1.15p + 2.85 = 5.84
Step-by-step explanation:
The equation above is not one you'd start off with to represent this problem. It is an intermediate step in the solution.
You can get there by realizing that the number of pounds of bananas is 3.8-p. Then the cost of the bananas is ...
banana cost = 0.75·(3.8-p) = 2.85 - 0.75p
Of course, the cost of apples is 1.90p. The total cost is then ...
apple cost + banana cost = total cost
1.90p + (2.85 -0.75p) = 5.84
Simplifying, this becomes ...
1.15p + 2.85 = 5.84 . . . . . . . . . . . . matches selection C
428.85 because value= initial value × multiplier^(no of years)
Multiplier=100-0.6
99.4÷100
=0.994
Value= 450 × 0.994^8
=428.847.....
Answer:
Average speed = 40 mph.
Step-by-step explanation:
Average speed can be calculated by using the formula
Speed = Distance ÷Time
Given Distance covered = 26\frac{2}{3} =\frac{80}{3}2632=380 miles.
Time =\frac{2}{3}32 hours .
Substituting the values of distance and time we have :
Average speed = \frac{\frac{80}{3} }{\frac{2}{3} }32380
=\frac{80}{3} .\frac{3}{2} =40380.23=40 miles per hour.
Answer:
Step-by-step explanation:
When cut by a diagonal, the parallelogram will be divided into two congruent triangles. By definition, congruent polygons have equal areas. Therefore, let the area of each of the triangle be
