His answer is not correct because when you add fractions, the sum is always greater than 11.

His answer is not correct because the sum cannot be less than either addend.

His answer is correct because 12 + 1 = 1312 + 1 = 13 and 15 + 10 = 2515 + 10 = 25.

His answer is correct because all the fractions are less than 11.

Hello,

If you are starting with the angle of 40 degrees, you have an adjacent side and hypotenuse. Therefore, it is a cosine relationship.

We can write:

cos(40) = adj / hyp
cos(40) = x / 220

To solve for x, simply multiply 220 by the cos(40).
You can write it as: 220 cos(40)

Good luck,

Find the slope of the line that passed though the two points (0,5) and (-9, -4)

OverLord2011 [107]

To find the slope, use the slope(m) formula:

$m=\frac{y_2-y_1}{x_2-x_1}$ and plug in the two points

(0, 5) = (x₁, y₁)

(-9, -4) = (x₂, y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-4-5}{-9-0}$

$m=\frac{-9}{-9}$ [two negatives cancel each other out and become positive]

m = 1 The slope is 1

Answer:

a. 14:45pm (It's really easy to convert to a 24-hour clock time, all you need to do is add 12 hours onto the hour. Eg. 2 + 12 = 14 so it will be 14:45.pm

b. The length of time between 11:45am and 2:45pm is 3 hours.

I don't know what c is sorry.

Hope that helps. x
