What you don't want is the value of r(t) becoming negative. Surely that would represent water escaping the reservoir.
How big can (t) get before water actually starts escaping the reservoir?
Essentially, to figure this out r(t) would have to be equal to 0.
700 - 40t = 0
40t=700
t=700/40=17.5
So the first answer is 17.5 seconds. After this amount of time has elapsed the reservoir will start to lose water as r(t) would become negative.
---------------
The reservoir had the least amount of water in it before it was being filled. That was when t=0. The volume of water in the reservoir wasn't negatively impacted as not enough water had escaped it during the 17.5 to 30 second period.
Answer:
5x+8y
Step-by-step explanation:
We can first open the brackets by using the distrubitive propety.
2(x+4y)+3x
2x+8y+3x
Now we can combine like terms.
5x+8y.
I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.

Answer:
1. $1.2
2. $0.14
Step-by-step explanation:
Step one:
given data
Black beans last week that cost $1.34
Step two:
This week's price
5 cans of beans cost $6.00
<u>The cost per can is</u>
= 6/5
=$1.2
<u>The difference in price</u>
=1.34-1.2
= $0.14
Answer:
Option (3)
Step-by-step explanation:
Statements Reasons
1). ∠L ≅ ∠N 1). Given
2). ∠LOM ≅ NMO 2). Given
3). MO ≅ MO 3). Reflexive property of congruence
4). ΔLMO ≅ ΔNOM 4). AAS postulate of congruence
Therefore, Option (3) will be the correct option.
Answer:
-42
Step-by-step explanation:
Cross multiply
5 * -2 = -10
8 * 4 = 32
-10 - 32 = -42
