Answer:
The points A (-8, -2) and C(-3, -9) are in the quadrant III.
Step-by-step explanation:
The cartesian plane is divided into four sections named quadrants, the four quadrants are organized by an opposite direction to the hands of the clock (you can see it in the attachment).
Therefore, each quadrant has a characteristic on the sign of its numbers, so:
• The quadrant I has the characteristic that both numbers are positive.
• The quadrant II has the characteristic that the number that represents its location in X is negative and the number that represents it location in Y is positive.
• The quadrant III has the characteristic that both numbers are negative.
• The quadrant IV has the characteristic that the number that represents its location in X is positive and the number that represents it location in Y is negative.
Having in account the information, we can classified the points and be sure that the A and the C are in the quadrant III, because they are the only ones in which their both numbers are negative.
Answer:
KArl should use 3/16 cups of chili powder
Step-by-step explanation:
Given that:
Recipe's requirement : 3/8 cups
Karl wants to use half : 1/2
The given question involves fractions. When the number of cups has to be divided into half, it will be multiplied with 1/2.
So,
Multiplying the chili powder requirement of the recipe to 1/2
Hence,
KArl should use 3/16 cups of chili powder
Answer:
936 jars of peanut butter contain less peanut butter than usual.
Step-by-step explanation:
1. First, we need to find how many jars of peanut butter that contain less peanut butter than advertised are produced every hour.
The factory produces 1200 jars of peanut butter every hour
3.25% of those jars have less peanut butter than advertised
So: multiply (the decimal form of the percent) to find the amount of peanut butter jars that contain less peanut butter than advertised.
So the factory produces 39 jars of peanut butter that contain less peanut butter than advertised.
2. Second, we need to find how many jars of peanut butter that contain less peanut butter than advertised in three 8 hour work days.
Lets add these work days together to find the total amount of hours:
So: three 8 hour work days totals to 24 hours
Since the factory produces 39 jars of peanut butter that contain less peanut butter than advertised per hour. Multiply to find the total amount of jars produced in three 8 hour work days.
A total of 936 peanut butter jars are produced in three 8 hour work days that contain less peanut butter than advertised.
3. If you want to double check your work do the following.
Since the factory produces 1200 jars an hour and 24 hours total three 8 hour work days. Multiply
So there is a total of 28800 jars produced in three 8 hour work days.
Then you can multiply 28800 by 3.25% of jars that contain less peanut butter to find the total amount of peanut butter jars that contain less peanut butter in three 8 hour work days.
