The millers plan on retiring soon. when they were first married they purchased 1,000 shares in a mutual fund that was at that time paying $10 a share. now, thirty years later it is paying $78 a share. what is the percent increase for the fund?

There is 680% increase for the fund.

Step-by-step explanation:

Since we have given that

Number of shares they purchased = 1000

Cost of per share at the time of their marriage = $10

So, Amount of fund will be

Cost per share after 30 years = $78

So, Amount of fund will be

Percentage of increase for the fund will be given as

Hence, there is 680% increase for the fund.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
