At the sewing store, Mariana bought a bag of mixed buttons. She got 80 buttons in all. 20 of the buttons were large. What percentage of the buttons were large?

Answers

Answer:

Step-by-step explanation:

To find the percent of large buttons, divide the number of large buttons by the total, and divide that by 100:

(20/80) x 100

0.25 x 100

= 25

So, 25% of the buttons were large.

Estimate the average annual growth rate of the world population for 1950, 1988, and 2010 using model 17 from the previous page.Model 17. Year Population Growth Rate (%)
1972 1.96
1982 1.73
1992 1.5
2002 1.22

Answers

although I don't see 1950, 1988, or 2010 on your model, I did calculate the average for 1972, 1982, 1992, and 2002: the average that I got was 1.6025 (this answer has not been rounded due to the fact that I don't know if you need to round it)

What is the value of x in the equation 4(2x + 12) = 0? −8

−6

6

8

Answers

You can skip 4 in that equation and you'll be left with 2x+12=0, which gives you 2x=-12 and finally, x=-6

4(2x+12)=0
8x+48=0
8x=-48
x=-6
