a factory could produce 84 toy robots in one day. They purchased some new equipment. Now they can produce 105 robots in one day.
kompoz [17]

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100  

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase

You have two nickels three dimes and a quarter. Using at least one of each coin, how many different amounts of money can you mak
Slav-nsk [51]
2 nickels (5 cents each)
3 dimes (10 cents each)
1 quarter (25 cents)

1 nickel, 1 dime, 1 quarter
5 + 10 + 25 = 40

2 nickels, 1 dime, 1 quarter
5(2) + 10 + 25 = 45

1 nickel, 2 dimes, 1 quarter
5 + 10(2) + 25 = 50

1 nickel, 3 dimes, 1 quarter
5 + 10(3) + 25 = 60

2 nickels, 2 dimes, 1 quarter
5(2) + 10(2) + 25 = 55

2 nickels, 3 dimes, 1 quarter
5(2) + 10(3) + 25 = 65

You can make 6 different amounts. 
You could also find this by multiplying however many coins you have all together.
2 * 3 * 1 = 6

X <-4 graphed as an inequality on a number line
iris [78.8K]
See it is < and not ≤ so we don't include -4

put a circle around -4  but don't shade it in
to get there, move 4 units left from 0


then we see x is less than -4
so shade to the left of the circle
