Answer:

SA = 200π cm²

Step-by-step explanation:

The slant height l is the hypotenuse of the right triangle inside the cone

The triangle is an 8- 15- 17 ( Pythagorean triple ) with l = 17

Then

SA = πrl + πr²

     =(π × 8 × 17) + (π × 8²)

     = 136π + 64π

     = 200π cm²

Answer:

in the right angle triangle,

p=15cm

b=8cm

[tex]h = \sqrt{15 {}^{2} + 8 {}^{2} } \\ = \sqrt{125 + 64} \\ = \sqrt{289} \\ = 17cm \\ sa = \pi \: rl + b \\ = \pi \: 8 \times 17 + \pi \: r {}^{2} \\ = 136\pi + 64\pi \\ = 200\pi[/tex]

Skewed Right I think. I'm not sure but try it

Answer:

C. Skewed Left

Step-by-step explanation:

Because the first 2 age group have minimal runners than the next 3 age groups spikes and the last 4 are very low once again. the spike occurs relavity near the beggining so if graphed it would be skewed left.

Answer:

Given: the angle of depression= 20°

Height of Kyle from the ocean = 30 feet

To find: how far is the whale from kyles biboculars?

Step-by-step explanation:

Let the distance between them be y

sin20° = [tex]\frac{33 }{y}[/tex]

=> 0.342 = [tex]\frac{33}{y}[/tex]          [  sin20° = 0.342]

=> y =  33/ 0.342

=> y = 96.5 ft

So, the distance between them is 96.5 ft

what is angle of depression?

The angle of depression is the angle formed by the horizontal line and the horizontal line's observation of the item. When we know the angles and the distance of an object from the ground, it is primarily utilized to find the distance between the two objects. If the line of sight is directed downward from the horizontal line, then an angle is created with the horizontal line.

The angle produced between the horizontal line and the observer's line of sight is known as the angle of depression if the object being observed is below the observer's level. The angle of depression is shown in the image below as.

24p-35

Step-by-step explanation:

Expand 4(6p-9)

=1+24p-36

Simplify 1+24p-36

=24p-35

Hope this helped!!!

Answer:

24p - 35

Step-by-step explanation:

1 + 4 ( 6p - 9 ) (multiply 4 x 6p = 24p and 4 x 9 = 36 )

1 +  24p - 36   ( subtract 1 on both sides on 1 and 36)

-1              -1     ( 36 - 1 = 35 )

       24p  - 35

31-5i

Answer:

31 - 5i

Step-by-step explanation:

(7 - 3i) * (4 + i)

Step 1: Multiply complex numbers 7 − 3i and 4 + i like you multiply binomials.

7 * 4 + 7i - 3i * 4 - 3i²

Step 2: By definition, i² is -1.

7 * 4 + 7i - 3i * 4 - 3 ( - 1)

Step 3: Do the multiplications.

28 + 7i - 12i + 3

Step 4: Combine the real & imaginary parts.

28 + 3 + (7 - 12)i

Step 5: Do the additions.

31 - 5i

The product of (7 - 3i) and 4 + i is 31 - 5i.

Ratios:

[tex]\frac{6}{1.8} =\frac{17}{x} \\\\6x=30.6\\x=5.1[/tex]

Answer:

tall candles = 39

Short candles = 52

Step-by-step explanation:

let tall candles be x

and short candles be y

No. Of candles sold = x + y =91

Money made from candles will be equal to = 8x + 5y = $572

These both are simultaneous linear equations.

x + y =91 ( multiply by 5)

5x + 5y = 455

8x + 5y = $572

Subtract them:

-3x = -117

x = -117/3

x = 39

put value of x in

x + y = 91

39 + y = 91

y = 91 - 39

y = 52

x shows tall candles so they are 39

y shows short candles so they are 52

Answer:

1 17/28 or 1.6071428571429 round: 1.61 in decimal form.

Answer:

y = 2

Step-by-step explanation:

3x + 6y = 18

3(2) + 6y = 18

6 + 6y = 18

Since 18 - 6 = 12, y will equal 2.

6 + 6(2) = 18

6 + 12 = 18

The coordinates to graph the equation would be (2, 2).
