The elementary Robotics Club is going on a field trip to the Kennedy Space Center. They will need to rent minivans to get to their destination. There are 35 fourth graders and 40fifth graders in the Robotics Club. Each minivan can only hold 8 people. How many minivans does the school need to rent?

10 minivans .

Step-by-step explanation:

Given: There are 35 fourth graders and 40fifth graders in the Robotics Club.

Total people = 35+40 = 75

Since each minivan can only hold 8 people.

Number of minivan required = (Total people) ÷ 8

= 75 ÷ 8

= 9.375≈ 10

Hence, the school needs to rent approx. 10 minivans .

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
