Answer:

95 = F

Step-by-step explanation:

C = 35

35 = (F - 32)*5/9

Multiply both sides by 9

35 * 9 = (F - 32) * 5 *9/9

315 = (F - 32) * 5 Divide both sides by 5

63 = F - 32 Add 32 to both sides.

63 + 32 = F

95 = F

My wife, an American, could never make these conversions. So I told her to multiply the Centigrade temperature by 2 and add 30. It would be close enough.

So 35 * 2 = 70

Add 30 = 100. That could do. It is a quick and easy way to get an estimate.

Find the number of moles in 508 g of ethanol (C2H5OH).

storchak [24]

To find the number of moles we start by calculating the molar mass:
M(C2H5OH) = 2*M(C) + 6*M(H) + M(O)
M(C2H5OH) = 2* 12.01 + 6* 1.008 + 16
M(C2H5OH) = 46.068g

This is mass of one mole of ethanol. Total mass of ethanol can be calculated by using formula:
m = N * M
Where:
m = total mass
N = number of moles
M = molar mass

We rearrange formula for N:
N = m / M
N = 508 / 46.068
N = 11.03

508g of ethanol contains 11.03 moles.

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation

Schach [20]

Answer:

y = 2x - 6

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is already given and is -6.

By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).

Use the two points to find the slope using the following equation.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }$

Plug the points into their respective positions and solve.

$m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2$

The slope is 2.

Your equation is y = 2x - 6.

Answer:

$8\frac{1}{5} acres$

Step-by-step explanation:

$7\frac{1}{4} + 3\frac{1}{5} - 2 \frac{1}{4} \\\\7\frac{1}{4} - 2 \frac{1}{4} = 5\\\\then:\\\\7\frac{1}{4} + 3\frac{1}{5} - 2 \frac{1}{4} = 5 + 3\frac{1}{5} = 8 \frac{1}{5}$
