Answer:
Step-by-step explanation:
d^2 = (x2 - x1)^2 + (y2 - y1)^2
x1 = 9
x2 = -1
y1 = -3
y2 = 8
d^2 = (-1 -9)^2 + (8 - - 3)^2
d^2 = (-10)^2 + 11^2
d^2 = 100 + 121^2
d^2 = 221
221 is not prime, it is 13 * 17 which doesn't factor down any further.
So
d = sqrt(221)
9514 1404 393
Answer:
C = πd = 2πr
1. C = 18.84 m
2. C = 43.96 ft
Step-by-step explanation:
The formula to find the circumference is C = πd = 2πr.
__
1. C = 2π(3 m) = 6π m = 6(3.14) m = 18.84 m
__
2. C = πd = (3.14)(14 ft) = 43.96 ft
Answer:
No solution is possible
Step-by-step explanation:
You didn't indicate the number of adults and children.
Answer:
Step-50*t + 30*m = 1500, (1) (pounds)
4*t + 3*m = 138. (2) (cubic feet)
From (2), express 3m = 138 - 4t, and substitute it into (1). You will get
50t + 10*(138-4t) = 1500, or
10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.
From this point, find the number of microwaves on your own.

Answer:
the answer would be the first one 321 m^2
Step-by-step explanation:
m=2(wl+hl+hw)=2·(10·6+6·6+6·10)=312
