Answer:

a rose bush cost $15.5 , a flat of petunias cost $9.75

Step-by-step explanation:

Let $x be the cost of rose bush and $y be the cost of a flat of petunias cost

3x + 7y = 114.75

2x + 6y = 89.5

x = 31/2 , y = 39/4

Jesse and Mark are jogging along the route shown at a rate of 12 miles per hour. They start by jogging south along Capitol Stree
Ilya [14]
The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours. Further, for Mark to be back to the starting point, the total distance covered is 2.75. Dividing the distance by 12 miles per hour, it will take Mark only 0.23 hours. Thus, Mark will reach the initial point first.

Degger [83]
Find the volume of the first figure, then find the volume of the second figure, then add them together.
