Answer:
I think it's called a term.
Hope this helps :)
Answer:
The answer is 5/3, 1 2/3, and 1.67
Step-by-step explanation:
The answer to this problem is simple as everything between the two lines will come out to be a positive. So the equation will end up coming out to be 3x+1+2=8.
Now we add the 1 and 2....
3x+3=8
To make this problems simple we can subtract the 3 from the left side and do the same on the right side making the equation say...
3x=5
Now we can make it easier to solve but it will not be a whole number. We now divide 3 from the left and right side leaving us with....
x = 5/3
So this answer could be 5/3 , 1 2/3, and 1.67
Answer:
It isn’t true that corresponding cross-sections have the same area.
Step-by-step explanation:
I got it off of khan academy.
Step-by-step explanation:
quick ...
first we need to find x.
and then we can calculate the area by
baseline × height / 2
which is here
12 × x / 2
x we get via Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
15² = 12² + x²
x² = 15² - 12² = 225 - 144 = 81
x = 9
the area of the triangle is then
12 × 9 / 2 = 6×9 = 54 m²
P + o = 40 (where p = peak and o= off-peak)
30p + 12o = 876
This can be done using elimination or substitution.
I will do elimination.
Multiply the first equation by -12. This will 'eliminate' the variable o.
-12p -12o = - 480
30p + 12o = 876
Now add the two equations together.
18p = 396
Divide both sides by 18
p = 22
40 - 22 = 18
Peak hrs. = 22
Off-Peak = 18
CHECK 22(30) + 18(12) = $876
