The science club plans to purchase "x" pizzas to feed the students at the science fair. Each pizza contains ten slices and each student at the science fair gets one slice. Write an algebraic expression for the total number of students that the science club can feed pizza

.

Step-by-step explanation:

Given:

The science club plans to purchase "x" pizzas to feed the students at the science fair.

Each pizza contains ten slices.

Each student at the science fair gets one slice.

Question asked:

Write an algebraic expression for the total number of students that the science club can feed pizza.

Solution:

Total number of pizzas plan to be purchased by Science club =

As each pizza contain = 10 slices.

pizzas contain =

As each student gets 1 slice, and we have slices:

Number of students fed from pizza slices =

Therefore, the total number of students that the science club can feed pizza is .

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
