Answer: f(3)=30 my good sir
Step-by-step explanation:
I honestly just guessed
Ur equations are :
C = 0.03t + 20...this is company A
C = 0.07t + 5....this is company B
now...for them to be equal...set them equal and solve for t
0.03t + 20 = .07t + 5
-5 + 20 = 0.07t - 0.03t
15 = 0.04t
15/0.04 = t
375 = t.......there would have to be 375 texts
Answer:
x > - 2
x ∈ ( - 2 ; + oo)
Step-by-step explanation:
- 5x < 10 | *(-)
5x > - 10 | : 2
x > - 2
x ∈ ( - 2 ; + oo)
Given that the amount of time varies inversely with G.
It can be written as,

where K is the constant.
We need to determine the time it takes to put out the fire when 200 gallons of water are used.
<u>The value of constant:</u>
When
, we get;


Thus, the value of constant is 96.
<u>Time taken:</u>
Substituting
and
in the formula
, we get;

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.
Hence, Option B is the correct answer.
Answer:
j=1/2k+5/2
Step-by-step explanation:
2j−k=5
Step 1: Add k to both sides.
2j−k+k=5+k
2j=k+5
Step 2: Divide both sides by 2.
2j/2=k+5/2
j=1/2k+5/2
