Answer:
EF=3.6
Step-by-step explanation:
I'm going to use Pythagorean Theorem for side EF.
4.8^2+EF^2=6^2
23.04+EF^2=36
-23.04 -23.04
EF^2=12.96
sqrt sqrt
EF=3.6
Answer:
C. 3.50
Step-by-step explanation:
He bought a lunch two times, so $1.75*2 = 3.50.
Let us solve for the total area. In this problem, we solve area 1 (the rectangle in the middle) and the area 2 ( the two half circle on the sides).
Solve for area 1:
Area rec = L * W = 5units * 4 units = 20 squared units
Solve for area 2:
Area cir = pi *r² = 3.14 * (2 units)² = 12.56 squared units
Total area = 20 + 12.56 = 32.56 foot²
Total cost = 32.56 foot² * ($23/foot²) = $ 748.88
Total cost is $748.88.
Divide 2 from both sides
t < 5/2
Hope this helps!
