kondaur [170]

Multiply

90 calories x

------------------- * -------------- will tell you how many calories Sarah drank.

12 oz 32 oz

12x = (90)(32) = 2880, so x = 240

Sarah drank 240 calories.

AURORKA [14]

Answer:

Using pythagorean therom √32 = c and b = 4

Step-by-step explanation:

a^2 + b^2 = c^2

Since a and b are the same just plug them in.

4^2 + 4 ^2 = c^2

16 + 16 = c^2

32 = c^2

√32 = c

After x + 2 over 2 minus X+1 over 3x have been combined using the least common denominator of 6x, what is the numerator?

SIZIF [17.4K]

Answer:

3x²+4x-2

Step-by-step explanation:

$\frac{x+2}{2}$ - $\frac{x+1}{3x}$ are not like terms. To make them like terms, you have to multiply the first fraction by 3x, and the second by 2.

This makes it $\frac{3x(x+2)}{6x}$ - $\frac{2(x+1)}{6x}$ , which can be expanded to $\frac{3x^{2}+6x}{6x}$ - $\frac{2x+2}{6x}$ .

This can be simplified to $\frac{3x^{2} +4x-2}{6x}$ .

The numerator is therefore 3x²+4x-2.

The formula for a cylinder's surface area is, as I said before : $\\ 2\pi rh+2\pi { r }^{ 2 }$ in this question, h=x

Let's plug the values and solve :

$2\pi rh+2\pi { r }^{ 2 }\\ \\ 2\cdot \pi \cdot 5\cdot 12+2\cdot \pi \cdot { 5 }^{ 2 }=2\cdot \pi \cdot 60+2\cdot \pi \cdot 25=120\pi +50\pi =170\pi \quad square\quad units\\ Answer\quad is\quad A$
