17) A marble paperweight shaped like a pyramid weighs 0.15 lbs. How much does a similarly shaped

erica [24]

Answer:

The weight of the larger marble paperweight is 4.05 lb

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its weights (or volumes) is equal to the scale factor elevated to the cube

Remember that the scale factor is the ratio between corresponding sides

Let

z ------> the scale factor

x -----> the weight of the larger marble paperweight

y -----> the weight of the original marble paperweight

$z^{3} =\frac{x}{y}$

In this problem we have

$z=3$

$y=0.15\ lb$

substitute and solve for x

$3^{3} =\frac{x}{0.15}$

$x=(27)(0.15)=4.05\ lb$

therefore

The weight of the larger marble paperweight is 4.05 lb

Last year, a janitorial supervisor had a gross income of $34,100, of which he contributed 8% to his 401(k) plan. If he got paid

rodikova [14]

There was a gross income of 34,100....8% goes to 401K plan..
8% of 34,100 = 0.08(34,100) = 2728

he gets paid bimonthly...so he gets paid twice a month...and being that there is 12 months in a year, he gets paid (12 * 2) = 24 times

2728/24 = 113.666 rounds to 113.67 each paycheck <==
