Answer: C. 100
Step-by-step explanation:
If the large tank is flowing at a constant rate of -6 per minute then we have to know that the water is moving from the tank. So is asking how many water will be left in the tank after 25 minutes.
You could use the equation
y = -6x + 250 where y is the amount of water left in the tank and x is the number of minutes.
So if x is 25 then plot it in and solve for y.
y = -6(25) +250
y = -150 +250
y= 100
Answer:
x=7
Step-by-step explanation:
isolate the variables by dividing each side by factors that dont contain the variable x=7
Answer:
200
Step-by-step explanation:
Use the ratio: 20/100 = 40/X
Simplify the ratio: 1/5 = 40/X
Cross Multiply: 1X = 200
Divide both sides by 1: 1X/1 = 200/1
Simplify: X = 200
Answer:
-5° < x < 26°
Step-by-step explanation:
The given parameters are;
The length of the rays forming the 62° = The length of the rays forming the 2·x + 10°
The length of the side opposite the 62° = 15
The length of the side opposite the 2·x + 10° angle = 14
Therefore, by construction, we have;
2·x + 10° < 62°
2·x < 62° - 10°
2·x < 52°
x < 52°/2
x < 26°
Also, we have that the angle 2·x + 10° is real, therefore;
0 < 2·x + 10°
-5 < x
Which gives;
-5° < x < 26°.
