Answer:

See below.

Step-by-step explanation:

In polar coordinate system, we have two parameters describing a point. The first one is its distance from the origin and second its angle with respect to the positive X axis.

The point ( 3 , pi ) will have a distance of 3 units from the origin. The angle made is pi radians or 180 degrees. The negative Y axis is at 180 degrees from the positive X axis.

Hence the point at a distance of 3 units on the negative Y axis is ( -3 , 0 )

pickupchik [31]

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli
german

Let x be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use 120-x gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

0.4x+0.7(120-x)=0.5\cdot120=60

\implies0.4x+84-0.7x=60

\implies24=0.3x

\implies x=80

so the answer is B.

Which statement about the solution of the inequality k<-3 1/4 is true?
Juliette [100K]

Answer: Last option

The number -8.4 is a solution to the inequality because -8.4 is located to the left of -3\frac{1}{4} on the number line.

Step-by-step explanation:

Note that: -3\frac{1}{4} =-3-\frac{1}{4} =-3.25

The inequality is:

k

The inequality is:

This means that the inequality includes all values of the number line that are less than -3.25 or that are to the left of -3.25

__-8.4_________-3.25_-3____0___0.9____________7.1__

Note that the number -8.4 is less than -3.25, because it is to its left on the number line.

Then the correct statement is:

The number -8.4 is a solution to the inequality because -8.4 is located to the left of -3\frac{1}{4} on the number line.
