PLS HELP Round the square root of 426 to the nearest thousandth

Mathematics
1 answer:
Arada [10]3 years ago
7 0

Answer:

20.640

Step-by-step explanation:

√426 ≈ 20.6397674406

The digit in the ten-thousandths place (bold) is more than 4 so 1 needs to be added to the thousandths place to round the number. Then, 39 thousandths becomes 40 thousandths, and the rounded number is ...

... 20.640

_____

Since you are asked to round to thousandths, you must show the thousandths digit of the rounded number, even though it is zero. This identifies the number as having precision to thousandths, even though it can be expressed using only hundredths.

Answer:

9) 1/2 (or 1:2, or 50%, or .50, depending on how your teacher wants it.

10) 2/3 (or 2:3, or 66.6%, or 0.66)

Step-by-step explanation:

9) Here are the possibilities of the cards you could pick

KQ, KJ, K10, QJ, Q10, J10

Since there are 6 possibilities and only 3 of them have one face card, the probability is 3/6, or 1/2.

10) It doesn’t matter which card you pick first.  The second card has a 1 in 3 chance of being the same card (whatever it is).  That means you have a 2 in 3 chance of it NOT being the same card.  So the probability is 2/3.

as part of a competition, diego must spin around in a circle 6 times and then run to a tree. the time he spends on each spin is
Leviafan [203]

The time he spent running is 13.80 seconds.

<h3>How much time did he spend running?</h3>

The equation that can be used to represent the time he gets to the tree is:

Time he gets to the tree = (time of each spin x total spins) + time he spent running

21 = (6 x 1.2) + r

21 = 7.20 + r

r = 21 - 7.20

r = 13.80 seconds

HURRYY!!! Identify the zeros of f(x) = (x − 3)(x + 9)(4x − 3).
tiny-mole [99]

Answer:

The value of x is -9, 3/4 and 3.

Step-by-step explanation:

In order to find the value of x, tou have to let f(x) equals to 0 :

Let f(x) = 0,

(x-3)(x+9)(4x-3) = 0

x - 3 = 0

x = 3

x + 9 = 0

x = -9

4x - 3 = 0

4x = 3

x = 3/4
