is because you said "the right rectangular prism shown" and then you didn't
show it. So all I can tell you is this:
-- The volume of each small cube is
(1/4) x (1/4) x (1/4) = 1/64 cubic inch .
-- The volume of the right rectangular prism that's not shown is
(length in inches) x (width in inches) x (height in inches) cubic inches.
The number of small cubes needed to fill the invisible right rectangular prism is ...
(volume of the missing right rectangular prism)
divided by
(volume of each small cube) .
That's
(volume of the alleged right rectangular prism)
divided by
(1/64 cubic inch)
= (64) times(volume of the rumored right rectangular prism) .

Answer:
The approximate score is:
Option: A
A. 62.5 points.
Step-by-step explanation:
Clearly from the graph we could observe that the line of best fit passes through (0,10) and (4.5,45).
Now we find the equation of line of best fit with the help of formula that is used to find the equation of a line passing through (a,b) and (c,d) as:
Here we have:
(a.,b)=(0,10) and (c,d)=(4.5,45)
Hence, the line of best fit is given as:
Now we are asked to find the math score if she does math homework for 7 hours a week i.e. we have to find the value of y when x=7.

Option: A
A. 62.5 points.
Let's write the an equation in slope intercept for for the line.
y-intercept=10
slope=rise/run=15/2=7.5
equation:
y=mx+b
y=7.5x+10
Solve for x=7
y=7.5(7)+10
y=52.5+10
y=62.5

Answer: 13 uniforms.
Step-by-step explanation: To solve the given problem we need to calculate the number of basketball uniforms that were purchased if the cost of each uniform was $60, using the given equation:
C=
substituting C=60:
multiplying both sides by n:
60n=40n+260
60n-40n=260
20n=260
n=260/20
n=13.
13 uniforms were purchased.

3 bags costs $9
1 bag will cost 9/3 = $3
Answer:it will be 3
Step-by-step explanation:
this is because if u divide 9 by three will equal 3
so if we remember our times table 3X3=9. so for (3bags 9$) (2bags 6$) and (1bag is 3$) So 3 dollars will be ur total

When you have a triangle and 2 of 3 angles are given the degrees and the last one is unknown, you subtract the two given degrees from each other to get your unknown, right? Just checking :D Tell me if I'm wrong from my notes and file attached please
Answers
No, that's not right. Sadly, the answer you entered on the
attached drawing is incorrect. It's slightly more complicated
than that ... only slightly.
First, think about this for a second: What if the two GIVEN angles
on the drawing had the same number of degrees ? Then by the
method you've been using, you would subtract them from each
other, and that would give you zero. So you would say that the
last angle is zero degrees ? Can you see that this doesn't really
work ?
Here's how it's really done:
It all rests on a rule about triangles. This is ALWAYS true, and
you should memorize it:
When you add up the degrees of all three angles
inside a triangle, the sum is ALWAYS 180 degrees.
So now, when you're given two of the angles, you know that
the unknown one must be exactly enough to bring the sum of
ALL of them up to 180 degrees.
Work it like this:
-- Take the two given angles.
-- ADD them.
-- Subtract their SUM from 180.
Now you have the third angle.
In the drawing you attached:
-- The given angles are 39 and 102 .
-- Add them: 39 + 102 = 141
-- Subtract the sum from 180: 180 - 141 = 39 .
The unknown angle is 39 degrees.
But that's the same as one of the given angles ! ? :-( ? :-(
That's OK. It's perfectly fine for two of the angles, or sometimes
even all three, to be the same size. They just have to all add up
to 180 degrees, and everything is fine.
