Answer:
120 Kg : 72 Kg
Step-by-step explanation:
Sum the parts of the ratio, 5 + 3 = 8 parts
Divide the quantity by 8 to find the value of one part of the ratio.
192 Kg ÷ 8 = 24 Kg , thus
5 parts = 5 × 24 Kg = 120 Kg
3 parts = 3 × 24 Kg = 72 Kg
192 Kg = 120Kg : 72 Kg in the ratio 5 : 3
You have to find the inverse of the function, then plug in -25 to that.
So:
First replace y with x and x with y
x=4(y+8)^2 - 9
Solve for y
x + 9 = 4(y+8)^2
(x + 9)/4 = (y+8)^2
Here square root both sides
sqrt((x + 9)/4) = y + 8
Subtract 8 from both sides
y = sqrt((x + 9)/4) - 8
Now plug in -25 in this equation
y = sqrt((-25 + 9)/4) - 8
solve
y = sqrt((-16 / 4)) - 8
Here, there is a negative number under the square root sign. So, -25 cannot be in the domain and the answer is D.
Answer:
The answer is 25.07 gallons/ 1 minute
Step-by-step explanation:
The question is asking for the unit rate of 752 gallons/30 minute as related to the minutes. So, you're looking for the ratio of gallons to 1 minute. To solve for this, you must divide the initial ratio of gallons to minutes by the initial minutes. so 752/30 and 30/30. Dividing 30 by 30 will give you 1. So, you know you'll be getting the unit rate. 752/30 is 25.0666666667. However, rounded to the nearest hundred will result in 25.07.
So your answer will be 25.07 gallons/ 1 minute (per minute).
The result follows from the fundamental theorem of calculus. Since is the derivative of , we have
