If Polo has n CDs, then \frac{50}n=\frac{25}{40} hence n=\frac{50\cdot40}{25}=80

Hence, they have a total of 80+40=\boxed{120\text{ CDs}}

HELP ASAP
joja [24]

Answer: The solutions are not viable because the amount of the sale cannot be negative.

Step-by-step explanation:

The solution A = -5 is not viable because A represents the amount of sale in dollars and so cannot be a negative number. The minimum amount that a person can make from sales is $0 so anything less than that is not viable.

For instance, if you are selling shoes for $4 each and make no sales in the day, your sales would be $0. It is not possible that your sales would be -$4.

Help help , Please help! Brainliest if correct! What was the equation of the graph below before it was shifted to the left 1.5 u
patriot [66]

Answer:

Option (D). G(x) = x³ - x

Step-by-step explanation:

Given function is the attachment,

G(x) = (x - 1.5)³ - (x - 1.5)

This function when translated by left by 1.5 units, rule for the translation is,

G(x) → G'(x + 1.5)

Therefore, translated function will be,

G'(x) = (x - 1.5 + 1.5)³ - (x - 1.5 + 1.5)

G'(x) = x³ - x

Therefore, Option (D) will be the answer.

PLEASE HELP
s344n2d4d5 [400]
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1
