So a-47=b
so total value =113 times 1,000,000=113,000,000=a+b
subtitute a-47=b into equation
a+a-47=113,000,000
add 47 to both sides
2a=113,000,047
divide both sides by 2
$56,500,023.5=a or <u>roughly</u> 56.5 million
a-47=b
56,500,032.5-47=b
56,499,976.5=b
so 56,500,023.5=a
56,499,976.5=b
You can express the edge lengths in terms of "cubes" or you divide the total volume by the volume of a cube. It works either way.
Edge lengths are
.. 80 cubes by 8 cutes by 13 cubes
so total volume is
.. (80 * 8 * 13) = 8320 cubes
In cubic inches, the volume is
.. (20 in)*(2 in)*(3 1/4 in) = 130 in^3.
The volume of a 1/4-in cube is (1/4 in)^3 = 1/64 in^3.
Then the number of cubes that will fit in the prism is
.. (130 in^3)/(1/64 in^3) = 8320 . . . . cubes
8320 cubes are needed to fill the rectangular prism.

Answer:
44.4%
Step-by-step explanation:
To calculate this, we proceed as follows.
we use the probability equation below;
P(A|B) = P(A and B) / P(B)
Applying the above to the scenario at hand;
P(red | car) = P(red and car) / P(car)
P(red and car) = 40% or simply 40/100 = 0.4
P(car) = 90% = 90/100 = 0.9
P(red | car) = 0.4/0.9
P(red | car) = 0.4444 which is = 44.44% ; to the nearest tenth of a percent = 44.4%
Answer:
x=6 y=-7
Step-by-step explanation:
rearrange the equation
3y=x-27 eq 1
2y=-4x+10 eq 2
Multiply eq 1 by 2, and eq 2 by 3
6y=2x-54
6y=-12x+30 subtract the two eq's
0=14x-84
84=14x
x=84÷14
<u>x=6</u>
solving for y sub. x either eq 1 or 2
3y=x-27
3y=6-27
3y=-21
y=-21÷3
<u>y=-7</u>
