Helpppp now please helpppp

algol [13]

The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
__________________________________________________________
Consider choice [A]: $\frac{(3)(4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
__________________________________________________________
Consider choice [B]: $\frac{(-3)(4)}{(6)}$ ;
= $\frac{-12}{6}$ ;
= "-2" ; Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________
Consider choice [C]: $\frac{(-3)(-4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [C]" .
__________________________________________________________
The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .

The speed of light in a vacuum is 29,980,000,000

sweet [91]

Answer:

$\huge\boxed{\sf 2.998 \times 10^{10}}$

Step-by-step explanation:

Given number:

29,980,000,000

Rules:

Move the decimal point after the first non-zero digit. (after 2)
Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).

The number will become:

2.998 × 10¹⁰

$\rule[225]{225}{2}$

In order, range, median, mode and mean. Round the mean to the nearest tenth. PLS HELP ASAP

Crazy boy [7]

Answer:

Range: 40

Median: 55

Mode: 72

Mean: 54.6

Step-by-step explanation:

First, let's put all of the numbers down.

32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72

Now, to find the range, subtract 72 - 32 = 40

To find the median, find the number in the middle

32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72

Because there are an even amount of numbers we will find the mean of those two numbers which would be 55.

To find the mode, look for the number that appears the most.

32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72

To find the mean, add everything up.

32, + 34, + 35, + 40, + 41, + 54, + 54, + 56, + 63, + 69, + 70, + 72, + 72, + 72 = 764

Then, divide. 764 ÷ 14 = 54.6 when rounded to the nearest tenth.

I hope that this helps, and you have a great day! :)

the height of a tower is 15m more than tiwce the height of a building find the height of the building if tower is 255m tall

PtichkaEL [24]

Answer: 120m

Step-by-step explanation:

Let the height of the building be represented by x.

Since the height of a tower is 15m more than tiwce the height of a building, the height of the tower will be:

= (2 × x) + 15

= 2x + 15

Since the tower is 255m tall, therefore,

2x + 15 = 255

2x = 255 - 15

2x = 240

x = 240/2

x = 120

The height of the building is 120m
