Answer: Yes

Step-by-step explanation:

You can tell that two of the numbers are only 2 apart, hence CB and CA, and the other one, AB, or the bottom side, is way less.

Answer:

YES IT IS

Step-by-step explanation:

For a triangle to be a right triangle, it must follow pythagorean theorem to find the hypotenuse (long side of triangle).

A squared + B squared = C squared

6 squared + 8 squared = 100

Since we squared our addends, we must find the square root of 100 (which is 10)

Since 10 is one of the side lengths for the hypotenuse since it is the longest, and we got 10 from pythagorean theorem, we know it is a right triangle.

Hope this helps you. Have a great rest of your day.

Suppose a box contains 3 defective light bulbs and 12 good bulbs. two bulbs are chosen from the box without replacement. find th

Mademuasel [1]

The probability that the bulb is good is 12/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective bulb is now 3/14.
Now you multiply the probabilities together to get (12/15)(3/14)=(4/5)(3/14)=12/70=6/35

Para encher 2/5 de uma piscina são necessários 60.000 litros de água. Qual é a capacidade dessa piscina?

natali 33 [55]

Answer:

A capacidade dessa piscina é de 150.000 litros de água.

Step-by-step explanation:

A capacidade da piscina é de x.

Para encher 2/5 de uma piscina são necessários 60.000 litros de água.

Isto implica que:

$\frac{2x}{5} = 60000$

$2x = 60000*5$

$x = \frac{60000*5}{2}$

$x = 150000$

A capacidade dessa piscina é de 150.000 litros de água.

Amrita thinks of a number. She doubles it, adds 9 , divides her answer by 3 and finally subtracts 1 . She obtains the same numbe

maks197457 [2]

Answer:

Amrita's number is 6

Step-by-step explanation:

x Double the unknown number

2x Add 9

2x + 9 Divide the answer by 3

2/3x + 3 Subtract 1

2/3x + 2 Set this equal to the original number

2/3x + 2 = x

-2/3x -2/3x Subtract 2/3x from both sides

2 = 1/3x Multiply both sides by 3

6 = x

The answer is 25%.

First: work out the difference between the two numbers you are comparing.

Decrease = Original Number - New Number

35-28=7

Then: divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100

7÷

28=.25

.25*100=25
