mary has 50 earring boxes. the boxes measure 1 inch on each side. how many rectangular prisms, each with a different sized base, could mary make by stacking all of the earring boxes?
Answers
50 earring boxes
1 inch on each side
Volume = a³ = (1 in)³ = 1 in³
1 in³ x 50 boxes = 50 in³
Let us do a prime factorization:
50 ÷ 2 = 25
25 ÷ 5 = 5
1 x 2 x 5 x 5
probable dimensions of the rectangular prisms
height x width x length
1 x 1 x 50
1 x 2 x 25
1 x 5 x 10
The can make 3 rectangular prisms based on the probable dimension.

The total amount in savings after 3 years is $ 4749.75
Solution:
Sonia and Jake received $4,500 in gift money and deposited it into a savings account that pays 1.85% simple interest
To find: Amount after 3 years
The total amount after 3 years is given as:
total amount = principal amount + simple interest
The simple interest is given as:
Here principal amount = $ 4500
Rate of Interest = 1.85%
Number of years = 3 years
Substituting the above values in formula we get,
Thus simple interest = $ 249.75
total amount = principal amount + simple interest
total amount = 4500 + 249.75
total amount = $ 4749.75
Thus the total amount after 3 years is $ 4749.75

assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54
remember if we can do
xy=0 then assume x and y=0
so factor
0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is
if you have
ax^2+bx+c=0 then
x=
x^2+7x+18
a=1
b=7
c=18
x=
x=
x=
i=√-1
x=
the zerose would be
x=

Wow ! This could be a real limbic tickler.
Let's try to find an easy way to do it . . .
If the watch is 30 seconds ahead at bedtime, and then it loses 20 of them
overnight, then from one morning to the next morning, it pulls ahead by
10 seconds.
So every morning, the watch is 10 seconds farther ahead than it was on
the previous morning.
That's the last time you have to worry about what it reads at night, or
what it loses overnight ! Just remember . . . 10 seconds farther ahead
every morning.
============================================
Now, how many times does it have to gain 10 seconds in order to add up
to 5 minutes ?
-- 10 seconds is (10/60) = 1/6 of a minute. So from one morning until
6 mornings later, the watch gains (6 x 1/6) = 1 whole minute.
-- And from one morning until (5 x 6) = 30 mornings later, it gains
(5 x 1) = 5 minutes.
The watch was correct on the morning of May 1. It gained 10 more seconds
every morning after that.
-- It was 1minute ahead on the morning of May (1 + 6) = 7.
-- It was 2 minutes ahead on the morning of May (7 + 6) = 13.
-- It was 3 minutes ahead on the morning of May (13 + 6) = 19.
-- It was 4 minutes ahead on the morning of May (19 + 6) = 25.
And it was 5 minutes ahead on the morning of May 31.

Set up proportions for the problem:
1 pound 4.5 pounds
________ x ___________
16 ounces x ounces
Cross multiply and solve for x.
x= 16 x 4.5
x= 72 ounces
So false, the recipe would call for 72 ounces of rice.
Answer: False
