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

Answer:

1/ 8 ^2

Step-by-step explanation:

When we are dividing exponents with same base all we do is subtract the denominator by the numerator (the exponent)

In this scenario we have  8^3 / 8^5

We are saying 8 * 8 * 8 / 8 * 8 * 8 * 8 * 8   When we cancel out the 8's were left with 1 / 8^2

or we could just subtract if that method is too long

Answer:

4024.62

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

Answer:

The Answer is 4024.62

Answer:

A

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

slope-intercept form  :)

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:

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:

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
