You can solve this with proportion
1) For 2h
9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles
For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get
x/4=9/2 => x=(9/2)*4=18 miles
2) 2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>
x= (320*7)/2 = 160 * 7 = 1120 acres
Good luck!!!
Answer:
6.25%
Step-by-step explanation:
To know the final probability that this has happened, we must multiply the probability of each event, they tell us that the probability that it is a girl is 1/2 and this happened 4 times, therefore:
(1/2) ^ 4 = 0.0625
that is, the probability that 4 girls are born is 6.25%
an unusual probability is considered when it is less than 5%, therefore, although it approaches this figure, it is not unusual
Answer:
the answer is 36
Step-by-step explanation:
beacuse if we use the pythagorean theorem for 9 and 12 we get 15 which means that the perimeter is P=9+15+12=36
Answer:
Step-by-step explanation:
f (x) = (5(-4)) + a) (3/5 + 4) ( 6 + b)
f (x) = (-20 + a) (6 2/5) (6 + b)
f ( -20 ) = -20 + -20 (a) (6 2/5) (6 + b)
f ( -20 - 6 2/5 ) = (a) (6 2/5 -6 2/5) (6 + b)
f (-26 2/5 - 6 ) = (a) (6-6 +b)
f (-32 2/5-6) = (a) (b)
