Question 14 of 18 A cone has a volume of 100 cubic inches and base area of 25 square inches. Malik is making a square prism that has three times the volume of the cone. The base of the prism has twice the area of the base of the cone. Select all that apply. The height of the cone is 12 inches. 5 inches. The radius of the base of the cone is The side length of the base of the prism is 10 inches. The height of the cone is twice the height of the prism. The height of the cone is equal to the height of the prism. The diameter of the base of the cone equals the side length of the base of the prism.

Question 7 A carpenter is making a backyard deck. In the measurements, he has determined that he needs to make a support triangle with an area 36m2. He knows that the base must be 1 less than 3 times the height. If the base is represented by 3x - 1 and height equals x. Find the equation that correctly shows the area of the triangle. 1 x(3x - 1) = 18 x(3x - 1) = 18 x(3x - 1) = 36 x(3x - 1) = 36

Question 2

QUESTION 8 On some highways, a car can legally travel 20 km/hr faster than a truck. Travelling at maximum legal speeds, a car can travel 120 kms in 18 minutes less than a truck. What are the maximum legal speeds for cars and for trucks? Car = 110 km/hr & Truck = 90 km/hr Car = 120 km/hr & Truck = 100 km/hr Car = 100 km/hr & Truck = 80 km/hr %3D O Car = 90 km/hr & Truck = 70 km/hr
