<span>The amount of dissolved oxygen in the Missouri River would decrease if large amounts of chemical waste were dumped into it. It would decrease because the chemical waste would feed on the microorganisms and reduce the amount of oxygen in the river.</span>
Answer:
let one even number be N
and another even number be N(N+2)
N(N+2)=360
n^2+2n-360=0
n^2+20n-18n-360=0
value of N= -20 ,18
but -20 not accepted
smaller number 18

Answer:
60km
Step-by-step explanation:
In 95 mins,he can run is 20km
In 1 min,he can run is 20/95
= 4/19in lowest
Now,
In 285 mins,he can run is=4/19*285
=4*15 in lowest
=60 km
Answer:
a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.
Step-by-step explanation:
a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.
b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.
c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.
