Answer:
17. 49
18. 62
Step-by-step explanation:
alright so all u gotta know here is that all triangles add up to 180 degrees
17. 50+83= 133
180-133= 49 degrees
18. 44+74= 118
180-118 = 62 degrees
Yes, because 0.004 is 0.04
I think the correct answer is C.5/24
Answer:
(6x+16) = 16+6x
Step-by-step explanation:
= 23x
again
23-x
= 23
Answer:
rectangle with maximum area has dimensions of 745 yd x 1490 yd
Step-by-step explanation:
the rectangular area is
Area = x*y , where x= side along the river , y = side perpendicular to the river
since we have only 2980 yd of fencing, the total fencing ( perimeter) will be
x+2*y = 2980 yd =a
then solving for x
x= a - 2*y
replacing in the area expression
A=Area = x*y = (a- 2*y) *y = a*y - 2*y²
the maximum area is found when the derivative with respect to y is 0 , then
dA/dy= a - 4*y = 0 → y=a/4 = 2980 yd /4 = 745 yd
then
x= a - 2*y = a - 2* a/4 = a/2 = 2980 yd /2 = 1490 yd
then the rectangle with maximum area has dimensions of 745 yd x 1490 yd
