Solve 22tq-s=6s for q.
Answer:
q= 7s/22t
Step-by-step explanation:
Hope it helps!
Answer:
[tex]q = \frac{7s}{22t} [/tex]
Step-by-step explanation:
We want to get q all by itself, so first add s to both sides to get rid of s on q's side
[tex]22tq = 7s[/tex]
Now to get q all by itself, all we have to do now is divide both sides by 22t to get
[tex]q = \frac{7s}{22t} [/tex]

Answer:
3 days would take the 15 workers to finish the same task
Step-by-step explanation:
In the questions of doing a job, the number of workers and the time are in an inverse proportional because if the number of workers is increased, then the time of finishing the job will decrease and vice versaThe relation between the number of workers and the time to finish any job is N × T = K, where, N is the number of workers, T is the time to finish the job, and K is constantLet us use this relation to solve the question
∵ 5 workers can complete a certain task in 9 days
∴ N = 5 workers and T = 9 days
→ By using the relation above
∴ 5 × 9 = k ⇒ (1)
∵ If there are 15 workers will make the same task
∵ They can finish it in x days
∴ N = 15 workers and T = x days
→ By using the relation above
∴ 15 × x = k ⇒ (2)
∵ k is the same task, then equate the left sides of (1) and (2)
∴ 15 × x = 5 × 9
∴ 15x = 45
→ Divide both sides by 15 to find x
∴ x = 3 days
∴ 3 days would take the 15 workers to finish the same task

Step-by-step explanation:
if f(x) =3(x+ 4) find f(-2)
Answer:
f(-2) = 6
Step-by-step explanation:
f(-2) = 3( -2 + 4)
f(-2) = (-6 + 12)
f(-2) = 6
Answer:
f(-2) = 6
Step-by-step explanation:
To find f(-2) we simply replace "x" in the functional expression with "-2" and evaluate the numerical answer:
f(x) = 3 (x + 4)
then
f(-2) = 3 (-2 +4) = 3 (2) = 6

Rubbing alcohol contains 70% isopropyl alcohol. Suppose you are adding 180ml of liquid that contains 45% isopropyl alcohol. How much liquid should be added of the higher concentration to obtain rubbing alcohol that is 70% isopropyl alcohol?
Starting with some solution of volume v and an alcohol concentration of 100c % , if you add 180 mL of 45% isopropyl to it, you get a mixture with a total volume of 180 mL + v.
Each mL of the starting solution contains c mL of alcohol. For example, if the concentration of the starting solution is 80% (so c = 0.8), then each mL contains 80% = 0.8 of one mL of alcohol.
Similarly, each mL of the added solution with 45% concentration contains 0.45 mL of alcohol.
You want the new solution to have a concentration of 70%, so that the ratio of the amount of alcohol in it to the total volume is 70%, meaning
cv + 0.45 (180 mL) = 0.7 (180 mL + v)
and you want to solve for v :
cv + 81 mL = 126 mL + 0.7v
cv - 0.7v = 126 mL - 81 mL
(c - 0.7) v = 45 mL
v = (45 mL) / (c - 0.7)
Judging by context clues, c lies somewhere between 0.7 and 1. (It can't be less than 0.7 because mixing this solution with any other solution of smaller concentration will never yield a solution of higher concentration.)
If, for example, c = 0.8, so that your starting solution is at 80% concentration, then you would need
v = (45 mL) / (0.8 - 0.7) = 450 mL
to be mixed with 180 mL of 45% solution to end up with 180 mL + 450 mL = 630 mL of 70% solution.
As another example, if you're mixing pure alcohol, so that c = 1, you would need
v = (45 mL) / (1 - 0.7) = 150 mL
to make a 180 mL + 150 mL = 330 mL batch of 70% solution. The fact that you would need less of a higher concentration solution is not surprising.

The sum of two imaginary numbers is -7-6i. If one of the numbers is -12+2i, what is the other imaginary number?
Answer:
5-8i
Step-by-step explanation:
-7-6i and -12+2i
Treat it as a polynomial. We all know that i=square root of -1, but in this case, treat it as a polynomial.
-12+5=-7
2i-8i=6i
So 5-8i

Answer:
204
Step-by-step explanation:
Following the order of operations, what is within the parenthesis is solved first.
65 x 3 = 195
Then, you add 9 to 195.
195 + 9 = 204
204 is the final answer.

A box with a square base and open top must have a volume of 13,500 cm3. Find the dimensions of the box that minimize the amount of material used
Answer:
Step-by-step explanation:
Let the side of the square base be x
h be the height of the box
Volume V = x²h
13500 = x²h
h = 13500/x² ..... 1
Surface area = x² + 2xh + 2xh
Surface area S = x² + 4xh ...... 2
Substitute 1 into 2;
From 2; S = x² + 4xh
S = x² + 4x(13500/x²)
S = x² + 54000/x
To minimize the amount of material used; dS/dx = 0
dS/dx = 2x - 54000/x²
0 = 2x - 54000/x²
0 = 2x³ - 54000
2x³ = 54000
x³ = 27000
x = ∛27000
x = 30cm
Since V = x²h
13500 = 30²h
h = 13500/900
h = 15cm
Hence the dimensions of the box that minimize the amount of material used is 30cm by 30cm by 15cm
