Does - |-4| = | -(-4)?

1 answer:

6 0

The first is an absolute value sign. But there is a - outside the first one so the -4 does become positive but then becomes negative again so you have -4

The second value is basically saying the same thing as -1x-4 which become a negative times a negative which is positive. You end up with 4.

So no it does not equal each other.

I do see an extra absolute value symbol though on the right side of the equal sign. But it looks like either way it would be -4 = 4 and that's not true. So either way it should be false.

The dimensions of a box that is a rectangular prism are 3 inches, 4 inches, and 6 inches. What is the length of the diagonal fro

Neporo4naja [7]

Answer:

7.8 in

Step-by-step explanation:

Given:-

- The dimension of rectangular prism:

(3 x 4 x 6) inches

Find:-

What is the length of the diagonal from the point R to point S, to the nearest tenth of an inch?

Solution:-

- We will set up an origin with coordinates ( 0 , 0 , 0 ) at point R. Then the coordinates of point S would be ( 3 , 4 , 6 ).

- Then we will use the distance between two points formula in cartesian coordinate system:

Distance = $\sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2 + (z_1 - z_2)^2}$

Where the coordinates of two points ( x1 , y1 , z1 ) & ( x2 , y2 , z2 ).

- Using R( 0 , 0 , 0 ) & S( 3 , 4 , 6 ), the distance |RS| would be:

$|RS| = \sqrt{(0 - 3)^2 + (0 - 4)^2 + (0 - 6)^2}\\\\|RS| = \sqrt{ 9 + 16 + 36}\\\\|RS| = \sqrt{61} = 7.81024$

- The distance |RS| to nearest 10th of an inch is = 7.8 in

Maria is ordering copy paper for her office. The office is low on white paper and on blue paper. She will play 3.50 per ream of

m_a_m_a [10]

So we know that the decimal place will move one right. Well basically let's assume she could have bought these expressions:

x 10 x 3.50 = 35.00
x 9 x 3.50 = 31.50 + 3.75 = 35.25
x 8 x 3.5 = 28 + 3.75 x 2 = 35.5
x 7 x 3.5 = 24.5 + 3.75 x 35.75

We know that there is a pattern. See how the cents goes .25 up each time. So we know she'd buy 6 reams of white because (6 x 3.5 = 21) + (4 x 3.75 = 15) = 36.

Mnenie [13.5K]

Answer:

$600

Step-by-step explanation:

Omar spent $600.

Essentially, we divide his total number of points:

1800

by the amount earned

300

we take that and multiply by 100 (our amount needed to be spent to earn points) and boom, problem solved.
