Marvin made some candles that each weighed 3/4 pound. He shipped them in a box that weighed 3 pounds. The total weight of the bo

zzz [600]

Total weight = 12
weight of box =3
12 - 3 = 9 lbs of candles
So how many times does .75 or 3/4 go into 9?
9/.75= 12, so 12 candles were shipped

A stack of $20, $50, and $100 bills was retrieved as part of a police investigation. There were 42 42 more $50 bills than $1

Misha Larkins [42]

Answer:

The number of $100 bills was 27.

The number of $50 bills was 69.

The number of $20 bills was 189.

Step-by-step explanation:

Let x be the number of $20 bills, y the number of $50 bills, and z the number of $100 bills.

Since there are three unknown values, we need three equations to solve the problem, all of them can be extracted from the question itself, two as the ratios between different bills and the last one as the sum of the total value of the money :

$y=z+42\\x=7*z\\20x+50y+100z = 9,930$

Substituting the first equations into the last, it is possible to find the value for z:

$20(7z)+50(z+42)+100z = 9,930\\z=\frac{9,930-2100}{290} \\z=27$

Knowing that there were 27 $100 bills, we can go back to the first two equations to find x and y:

$y=z+42=27+42\\y= 69\\x=7*z=7*27\\x= 189$

The number of $100 bills was 27.

The number of $50 bills was 69.

The number of $20 bills was 189.

What are the first five partial sums of the arithmetic sequence an = 0.05(n – 1) – 0.6?

Gnoma [55]

The sum of the arithmetic sequence given by
<span>an = 0.05(n – 1) – 0.6
will be given by:
a1=0.05(1-1)-0.6=-0.6
a2=0.05(2-1)-0.6=-0.55
a3=0.05(3-1)-0.6=-0.5
a4=0.05(4-1)-0.6=-0.45
a5=0.05(5-1)-0.6=-0.4
thus the summation will be:
-0.6+(-0.55)+(-0.5)+(-0.45)+(-0.4)
=-2.5
hence
S5=-2.5</span>
