The angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.

Let x represent the angle

Tan x=Height/Horizontal distance

Tan x =10,000/30,000

x=Tan^-1 (1/3)

x=18.4°

Inconclusion the angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.

Answer:

The surface area is 1.5cm

Step-by-step explanation:

6/4=1.5cm

Answer:

216 cm²

Step-by-step explanation:

A cube has 6 square faces.

The area of 1 face = 6 × 6 = 36 cm² , then

SA = 6 × 36 cm² = 216 cm²

Answer:

3 hours

160 - 55 = 105

105 ÷ 35 = 3

Answer:

3 hours

Step-by-step explanation:

First, we must turn this into an equation:

35n + 55 = 160

N = number of hours

Next, solve:

35n + 55 - 55 = 160 - 55

35n = 105

n = 3

When you rub the balloon on your hair, the balloon becomes negatively charged because it gains electrons from your hair.

Step-by-step explanation:

Is it multiple choice? If not the answer is anything positively charged. Negative and positive ions attract, while synonymous (N,N or P,P) repel. Pieces of paper, the wall, or even your clothing are all possibly positive charged objects the balloon could stick to.

Answer:

11/4

Hope this helps

Answer:

11/4

Step-by-step explanation:

An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.

You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8

then we add 8/4 with 3/4 to get 11/4

Answer:

x = 10

Step-by-step explanation:

OA = OD ( both radii of the circle )

OD = OB + BD = x + 16

OB is at right angles to OB ( line from centre to midpoint of chord is right )

Using Pythagoras' identity in right triangle ABO

OA² = OB² + AB² , that is

(x + 16)² = x² + 24²

x² + 32x + 256 = x² + 576 ( subtract x² from both sides )

32x + 256 = 576 ( subtract 256 from both sides )

32x = 320 ( divide both sides by 32 )

x = 10

Answer:

Aonnalin, great name  :)  answer as below

Step-by-step explanation:

They tell us to use slope-intercept form.   This is something you will just have to remember  y = mx+b    

It is confusing b/c there is the other one, the point-slope formula too.  but just remember both and know that the point-slope one is to get to the slope-intercept one.    y-y1 = m(x-x1)  

m= slope

m = (y2-y1) / (x2-x1)

P1= (0,7)  in the form (x1,y1)

P2 =(8,-2) in the form (x2,y2)

m = -2-7 / 8-0

m = -9 / 8

now that we have the slope, just use either point with the point-slope

y-7 = (-9/8)(x-0)

y-7 = -9x/8

y = -9x/8 + 7

y = [tex]\frac{-9}{8}[/tex] X + 7

Step-by-step explanation:

the value in 70 days can be determined using his formula

FV = P (1 + r)^n

FV = Future value  

P = Present value = 650

R = growth rate = 20%

N = number of weeks = 70 / 7 = 10 weeks

650 x (1.2)^10 = 4024.62
