Answer:

<h2>one-third of the volume </h2>

Step-by-step explanation:

\text{The formula of volumes of:}\\\\a\ cone:\ V_{cone}=\dfrac{1}{3}\pi r_1^2H_1\\\\a\ cylinder:\ V_{cylinder}=\pi r_2^2H_2\\\\\text{If cone and cylinder are with the same radius and height, then:}\\\\r_1=r_2=r\ \text{and}\ H_1=H_2=H\\\\V_{cone}=\dfrac{1}{3}\pi r^2H,\ V_{cylinder}=\pi r^2H\to V_{cone}=\dfrac{1}{3}V_{cylinder}

Evaluate the expression described below if the variable given is 9. Two times the difference of one-third of a number and three.
Mrac [35]

Answer:

Option C is correct.

The answer for the given expression is 0.

Step-by-step explanation:

Given the statement: Two times the difference of one-third of a number and three. and also variable given is 9.

Let x be the variable or number.

"One-third of a number"  means \frac{1}{3}x

Also, "difference of one third of a number and three " means \frac{1}{3}x-3

Now, "Two times the difference of one-third of a number and three" means   2 \times (\frac{1}{3} x -3)

Then, the expression for the given statement : 2 \times (\frac{1}{3} x -3)

Substitute the value of x =9 in above expression we have;

2 \times (\frac{1}{3}(9) -3) = 2 \times (3 -3) = 2 \times (0) = 0

therefore, the answer for the given expression is, 0

i've asked this 5 times already if y'all answer or points and answer with nmo explanation i am going to download photomath

Answer:

Rahm: 0.8

Bain: 1.2

Step-by-step explanation:

For this, they ask for the rate of change or slope. To find slope you can use slope formula to get your slope/rate of change.

Steps for Rahm:

We can take points (10,8) and (20,16) and find the slope with the following formula: \frac{y^2-y^1}{x^2-x^1}

\frac{16-8}{20-10} = 0.8

This is the rate of change for Rahm

Steps for Bain:

Take the points (5,6) and (11,13.2) and plug them into the Slope Formula:

\frac{13.2-6}{11-5} = 1.2

Therefore, Bain hiked faster than Rahm for he had the higher rate of change compared to Rahm.

Answer:

8x + 3

Step-by-step explanation:

The cost of 5 t-shirts and 3 skirts

= 5(x - 3) + 3(x + 6)

= 5x - 15 + 3x + 18

= (5x + 3x) + (-15 + 18)

= 8x + 3
