Maggie has a collection of 1,200 Pennies. Of these, 25% are dated before 1980, 35% are dated from 1980-2000.and the rest are dat

chubhunter [2.5K]

Answer:

A- 480

Step-by-step explanation:

First, I'm going to work out 25% of 1200 for the before 1980 pennies.

10% = 120

20% = 240

5% = 60

240 + 60 = 300 pennies before 1980.

Next, work out 35% of 1200 instead.

20% = 240

+ 10%

30% = 360

+ 5% = 60

35% = 420 pennies from 1980-2000

Finally, work out how many pennies are leftover.

300 + 420 = 720

1200 - 720 = 480

A is the answer.

Hope this helps and have a good day!

Which equation represents Grant's path?

amid [387]

Answer:

$y=4-\frac{x}{2}$

Step-by-step explanation:

Find the coordinates of point A and point B

Looking at the graph

we have the points

A(8,0) and B(-4,6)

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{6-0}{-4-8}$

$m=\frac{6}{-12}$

$m=-\frac{1}{2}$

step 2

Find the equation in point slope form

$y-y1=m(x-x1)$

we have

$m=-\frac{1}{2}$

$point\ A(8,0)$

substitute

$y-0=-\frac{1}{2}(x-8)$

Convert to slope intercept form

$y=mx+b$

Distribute in the right side

$y=-\frac{1}{2}x+4$

rewrite

$y=4-\frac{1}{2}x$ -----> $y=4-\frac{x}{2}$
