First replace all variables with the respective numbers.

V = (1/3) x 3.14 x 15^2 x 9

according to PEMDAS, work out your exponent next

V = (1/3) x 3.14 x 225 x 9

multiply

V = 1.04667 x 225 x 9

V = 235.5 x 9

V= 2,119.5

ANSWER: the volume is 2,119.5 cm

Sofia places 26 tiles representing each letter of the alphabet into a bag. Five of the tiles represent the vowels A, E, I, O, an
mars1129 [50]

Answer:

42 times.

Step-by-step explanation:

The number of total alphabet = 26 tiles

The number of vowels = 5

The number of consonant = 26 - 5 = 21

Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.

The probability to select consonant at first time = 21/26

Total tiles after the first selection = 26 - 1 = 25

The probability to select vowels at second time = 5/25

The probability to select consonant and vowels = \frac{21}{26} *\frac{5}{25} =\frac{21}{130}

Sofia will draw two tiles from the bag 260 times.

The prediction for the number of times Sofia will select a consonant tile and a vowel tile = \frac{21}{130} *260=42 \ times

2x + 19 and x + 23 are alternate exterior angles. What is the value of x? *
Mamont248 [21]

Answer:

4

Step-by-step explanation:

2x+19=x+23

We simplify the equation to the form, which is simple to understand

2x+19=x+23

We move all terms containing x to the left and all other terms to the right.

+2x-1x=+23-19

We simplify the left and right sides of the equation.

+1x=+4

We divide both sides of the equation by 1 to get x.

x=4

Tính đạo hàm của y=2x-1-căn3x-0
adoni [48]

Answer:

The derivative is

\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\

Step-by-step explanation:

The function is given by

y = 2x - 1 - \sqrt {3x}

Differentiate with respect to x, we get

\frac{dy}{dx} = 2 - 0 - \frac{2\sqrt3}{\sqrt x}\\\\\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\
