Answer:

500

Step-by-step explanation:

375/3=125

125*4=500

Given:

A diagram of a composite figure.

Radius of cone and hemisphere is 8 cm.

Height of the cone is 15 cm.

To find:

The volume and the surface area of the composite figure.

Solution:

Volume of a cone is:

[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]V_1=\dfrac{1}{3}\pi (8)^2(15)[/tex]

[tex]V_1=\pi (64)(5)[/tex]

[tex]V_1=320\pi[/tex]

Volume of the hemisphere is:

[tex]V_2=\dfrac{2}{3}\pi r^3[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]V_2=\dfrac{2}{3}\pi (8)^3[/tex]

[tex]V_2=\dfrac{1024}{3}\pi [/tex]

[tex]V_2\approx 341.3\pi [/tex]

Now, the volume of the composite figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=320\pi +341.3\pi[/tex]

[tex]V=661.3\pi[/tex]

The volume of the composite figure is 661.3π cm³.

The curved surface area of a cone is:

[tex]A_1=\pi r\sqrt{h^2+r^2}[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]A_1=\pi (8)\sqrt{(15)^2+(8)^2}[/tex]

[tex]A_1=\pi (8)\sqrt{289}[/tex]

[tex]A_1=\pi (8)(17)[/tex]

[tex]A_1=136 \pi [/tex]

The curved surface area of the hemisphere is:

[tex]A_2=2\pi r^2[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]A_2=2\pi (8)^2[/tex]

[tex]A_2=2\pi (64)[/tex]

[tex]A_2=128\pi [/tex]

Total surface area of the composite figure is:

[tex]A=A_1+A_2[/tex]

[tex]A=136\pi +128\pi[/tex]

[tex]A=264\pi[/tex]

The total surface area of the composite figure is 264π cm².

Therefore, the correct option is A.

Answer:

the daily periodic rate is 0.0411%

Step-by-step explanation:

Given that

The Annual percentage rate is 14.99%

We need to find out the daily periodic rate for the credit card

As we know that

Daily periodic rate = annual percentage rate ÷ 365 days

= 14.99%  ÷ 365  days

= 0.0411%

Hence, the daily periodic rate is 0.0411%

Answer:

1/216

Step-by-step explanation:

Hi there!

A function is a set of ordered pairs that do not have same x-values.

In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.

From the question above, you notice that two of the choices have same x-values and others don't have.

The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.

Any questions can be asked through comment.

Furthermore, a function is also a relation but a relation isn't always a function.

Hope this helps, and Happy Learning! :)

Answer:

C

Step-by-step explanation:

Just took the quiz

Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.

We have a c value of -1 which is where the y axis is intercepted.

We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.

The only logical conclusion therefore, is that k is greater than zero.

Answer:

11/36

Step-by-step explanation:

To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.

Answer:

C

Step-by-step explanation:

Looking at the first point we know that it can't be A

Then we can easily see that the rate of change is not level (which means it isn't linear)

this leaves option C

Another way to solve this is just by plugging in points

B. 720 ways

Step-by-step explanation:

To solve you would multiple 6x5x4x3x2x1 .

The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.

Given that,

Number of players = 6

Assigned position on a baseball = 6

We have to determine,

In how many ways can 6 players be assigned to 6 positions on a baseball team.

According to the question,

To solve this problem assuming that any player can play any position.

The formula to find [tex]^nP_r[/tex] is given by:

[tex]^np_r[/tex] is the permutation of arrangement of 'r' objects from a set of 'n' objects, into an order or sequence.

The formula to find permutation is:

[tex]^np_r = \frac{n!}{(n-r)!}[/tex]

Where, n = 6 and r = 6

Therefore,

[tex]^6p_6 = \frac{6!}{(6-6)!} \\[/tex]

     [tex]= \frac{6\times5\times 4 \times 3 \times 2 \times 1}{0!} \\\\= \frac{720}{1} \\\\= 720 \ ways[/tex]

Hence, The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.

[tex]57 + x + 23 = 180\\x = 180 - 57 - 23\\x = 100\textdegree[/tex]

Answer: 100.

Answer:

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for B

∠ B = 180° - (90 + 63)° = 180° - 153° = 27°

(b)

Using the sine ratio in the right triangle

sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )

x × sin63° = 15 ( divide both sides by sin63° )

x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )

(c)

Using the tangent ratio in the right triangle

tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )

y × tan63° = 15 ( divide both sides by tan63° )

y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )
