Answer:
X = 0
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
−2x+7−7=7−7
−2x=0
Step 2: Divide both sides by -2.
−2x
−2
=
0
−2
x=0
Hope this helps!
V=πr²h+(2/3)πr³
<span>πr²h+(2/3)πr³=V
</span>πr²h=V-<span>(2/3)πr³
</span>h=(V-(2/3)πr³) / (<span>πr²)
h=V/</span><span>πr² - 2/3r
Answer i: </span>h=V/<span>πr² - (2/3)r
Data:
V=245
r=7
h=(245 / 49</span>π) - (14/3)
h=(5/π) - (14/3)
h=(15-14π)/3π
h=-3.075
Answer ii: h=-3.075
Just set it up like your average addition problem:
2x + y = 4
+ 3x - y = 6
then add one term at a time; work from left to right.
5x = 10 is your result. your y's cancel out.
I believe the answer would be indirect proof as it would have no basis of evidence.
Assuming base two number, then
1100110
= (1 × 2^6 ) + (1 × 2^5 ) + (0 × 2^4) +(0 × 2³) + (1 × 2²) + (1 × 2^1) + (0 × 2^0)
= 64 + 32 + 0 + 0 + 4 + 2 + 0 = 102
Hence =
