Answer:
The pitcher plant's approximate volume is 24.492
.
Step-by-step explanation:
We are given that a pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.
Let the radius of a cylinder = r = 1 cm
and the height of a cylinder = h = 7.8 cm
As we know that the volume of a cylinder is given by;
The volume of a cylinder = ![\pi r^{2}h](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7Dh)
=
{taking approximate value of
to be 3.14}
= ![3.14 \times 7.8](https://tex.z-dn.net/?f=3.14%20%5Ctimes%207.8)
= 24.492 ![\text{cm}^{3}](https://tex.z-dn.net/?f=%5Ctext%7Bcm%7D%5E%7B3%7D)
Hence, this pitcher plant's approximate volume is 24.492
.

Answer: Choice D which is (13-5x)/(2x-8)</h3>
======================================
Explanation:
Fractions in all honesty are quite simply a pain. They complicate things greatly. Luckily we can cancel out some of the fractions here. Note we have inner fractions 3/(x-2) and 4/(x-2), both of which having a denominator of (x-2).
Focus on just the stuff up top which is 3/(x-2) - 5. Multiply both of the terms by the expression (x-2) to get the fraction 3/(x-2) turning into just 3. The 5 becomes 5(x-2) = 5x-10. So we end up with the expression 3 - (5x-10) = 3-5x+10 = 13-15x up top
Similarly, in the denominator we have 2 - (4/(x-2)) which becomes 2(x-2) - 4 = 2x-4-4 = 2x-8 when we multiply everything by (x-2) to cancel out that inner fraction.
So that's how we end up with (13-5x) all over (2x-8) as our final answer.
Answer:
Step-by-step explanation:
X∝Y
4∝40
X∝23
(23×4) ÷ 40 = 2.3
= -1/2 + 2/3 - 7/6
= -3/6 + 4/6 - 7/6
= -6/6
= -1
answer
-1
