Answer:

1 is false

2 is true

3 is false

4 is false

Step-by-step explanation:

y-33=-2

y-33+32=-2+33

y=31

31=3x-2

31+2=3x-2+2

33=3x

33/3=3x/3

11=x

solution is (11,31)

graph of y=-3x-2... y=31 would be a horizontal line on 33 at the y axis

No, because an right triangle is 90 degrees. And an acute angle is ALWAYS less than 90 degrees.

Above I showed a quick diagram of a right triangle or a 90 degree angle.

An acute angle is less than 90 degrees

The width of a piece of paper is 8.5in the length is 11in and the thickness is 0.0037inches there are 2700sheets sitting in a ca

Musya8 [376]

Answer:

934.2 in³

Step-by-step explanation:

The following data were obtained from the question:

Width (W) = 8.5 in

Length (L) = 11 in

Thickness (T) = 0.0037 in

Number of paper = 2700 sheets

Volume occupied by the 2700 sheets of paper =?

Next, we shall determine the volume of 1 sheet of paper. This can be obtained as follow:

Width (W) = 8.5 in

Length (L) = 11 in

Thickness (T) = 0.0037 in

Volume (V) =?

Volume = Length × Width × Thickness

Volume = 11 × 8.5 × 0.0037

Volume = 0.346 in³

Thus, the volume of 1 sheet of paper is 0.346 in³

Finally, we shall determine the volume occupied by the 2700 sheets of paper as follow:

Volume of 1 sheet of paper = 0.346 in³

Volume of 2700 sheets of paper =?

1 sheet of paper occupied 0.346 in³.

Therefore, 2700 sheets of paper will occupy = 0.346 × 2700 = 934.2 in³

Thus, the volume occupied by the 2700 sheets of paper is 934.2 in³.

I added three non-unit fractions together to make a whole. What three fractions could that be?

Anna11 [10]

Answer:

For example $\frac{2}{6}$

Step-by-step explanation:

A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.

For example: $\frac{2}{6}$ , because 3· $\frac{2}{6}$ = $\frac{6}{6}$ = 1

Infinitely many solutions can be found: for example $\frac{3}{9} , \frac{4}{12} , etc$
