Answer:33.3
Step-by-step explanation: a mile is 1000×3 so it's 3000/90
Answer:320
Step-by-step explanation: 8 bats equals 40 grams of insect. 8 x 5= 40. 64 bats equals 320. 64 x 5 =320.
The distance between two points can be calculated using the following formula:
distance = sqrt [ (x2-x1)^2 + (y2-y1)^2]
Now, we are given the two points (5,4) and (1,-2)
Substitute with the given points in the above equation to get the distance as follows:
distance = sqrt [(1-5)^2 + (-2-4)^2]
distance = sqrt [16+36] = sqrt[52]
distance = 2√13 = 7.2111 units
Answer:
x=2; y=-1
Step-by-step explanation:
Hello,
(1) 6x+7y=5
(2) 2x-3y=7
We multiply equation (2) by 3, it gives
6x-9y=21 and we subtract from (1)
6x-9y-6x-7y=-16y=21-5=16
So y = -1
we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2
