Given the right triangle with one side unknown

Use Pythagorean Theorem to find the value of x:

Answer:

SA = 200π cm²

Step-by-step explanation:

The surface area is calculated as

SA = area of base + area of curved surface

     = πr² + πrs ( r is the radius and s the slant height )

Using Pythagoras' identity in the right triangle to find s

s² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )

s = [tex]\sqrt{289}[/tex] = 17

SA = π × 8² + π × 8 × 17

      = 64π + 136π

      = 200π cm²

Answer:

Step-by-step explanation:

For example, to find the common (positive) multiples of 4 and 6, we might list: Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, … Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, … The numbers 12, 24, 36, and 48 appear on both of these lists, and more would appear if the lists were longer.

Answer:

6: 6; 12; 18; 24; 30; 36; 42; 48; 54; 60; 66; 72

4: 4; 8; 12; 16; 20; 24; 28; 32; 36; 40; 44; 48

Given:

The figure of a right triangle ABC.

To find:

The trigonometric ratios [tex]\sin B, \tan A, \cos B[/tex].

Solution:

Using Pythagoras theorem,

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]AB^2=AC^2+BC^2[/tex]

[tex](10)^2=(6)^2+BC^2[/tex]

[tex]100-36=BC^2[/tex]

[tex]64=BC^2[/tex]

Taking square root on both sides.

[tex]\sqrt{64}=BC[/tex]

[tex]8=BC[/tex]

So, measure of BC is 8 units.

Now,

[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\sin B=\dfrac{AC}{AB}[/tex]

[tex]\sin B=\dfrac{6}{10}[/tex]

[tex]\sin B=\dfrac{3}{5}[/tex]

Similarly,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

[tex]\tan A=\dfrac{AC}{BC}[/tex]

[tex]\tan A=\dfrac{6}{8}[/tex]

[tex]\tan A=\dfrac{3}{4}[/tex]

And,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos B=\dfrac{BC}{AB}[/tex]

[tex]\cos B=\dfrac{8}{10}[/tex]

[tex]\cos B=\dfrac{4}{5}[/tex]

Therefore, the required trigonometric ration are [tex]\sin B=\dfrac{3}{5}, \tan A=\dfrac{3}{4}, \cos B=\dfrac{4}{5}[/tex].

Answer:

C; 62 to 68 inches

Step-by-step explanation:

Here, we want to get the population range that is having a probability of 68%

From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%

From the question;

1 standard deviation above the mean is 65 + 3 = 68

1 standard deviation below the mean is 65-3 = 62

so the range of the height of the population is 62 to 68 inches

Answer:

Answer:

V = 408    SA = 378

Step-by-step explanation:

To find the volume, you need to first find out the area and multiply it by overall length.

A = 1/2 (6)(8)

= 24

Volume = 24 x 17

= 408

Surface Area

SA = Front and Back + Right Side + Left Side + Bottom

= 2 [1/2 (6) (8)] + (17 x 10) + (3 x 8) + (17 x 8)

= 2 (24) + 170 + 24 + 136

= 48 + 170 + 24 + 136

= 378

Answer:

8 should be the answer.

Step-by-step explanation:

4 × 2 = 8

Answer:

The answer should be 54, lmk if it works

Step-by-step explanation:

2x + y = 21

Solving

2x + y = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

2x + y + -1y = 21 + -1y

Combine like terms: y + -1y = 0

2x + 0 = 21 + -1y

2x = 21 + -1y

Divide each side by '2'.

x = 10.5 + -0.5y

Simplifying

x = 10.5 + -0.5y
