Answer:
C.1767.8 square feet
Step-by-step explanation:
use heron's formula to solve (see attached)
perimeter = 50 + 75 + 75 = 200 feet
p = perimeter / 2 = 200/2 = 100
from heron's formula
A = √ [ p(p-a)(p-b)(p-c)]
= √[100 (100-50)(100-75)(100-75) ]
= √[100·50·25·25 ]
=√3,125,000
= 1767.77 (within rounding errors, closest answer is C)
Answer:
Only (5,4)
Step-by-step explanation:
2x+4y=6x-y
2*5+4*4=6*5-4
10+16=30-4
26=26
So F(6) means 6 on the x axis then look to see where the graph is on the Y axis,
in this case on x 6 y=4
Answer:
C.
and 
Step-by-step explanation:
The proportion between these fractions is true. Multiply 4/10 (numerator and denominator) by 2.5 to get 10/25. This is the only correct option.
Hope it helps!
