Answer:

12 ft  9 5/6 inches

Step-by-step explanation:

We can use proportions to solve this.  Put the height of the object over the shadow.  Change the height of the object to inches

Alonzo

5 ft 11 inches = 5 ft *12 inches/ft + 11 inches = 60 inches + 11 inches = 71 inches

2 ft shadow = 2* 12 inches/ ft = 24 inches

Basketball goal

4 ft 4 inches =  4 ft *12 inches/ft + 4 inches = 48inches + 4 inches = 52 inches

Alonzo             Basketball      

71 inches         x inches tall

------------   = --------------------

24 inches     52 inches

Using cross products

71*52 = 24*x

Divide each side by 24

71*52/24 = 24x/24

923/6 =x

Lets change this to a mixed number

6 goes into 923  153 times   with 5 left over

153  5/6 inches

Now we need to change inches to feet

How many time does 12 go into 153  12 times  (12*12 =144  with 9 left over)

12 ft  9 5/6 inches

If the function is: f(x) = 4^x     - 8

D = {XeR}
R = {YeR|Y≥0}


if the function is: <span>f(x)=4^(x-8)

</span>D = {XeR}

1.3x - 10= 0.8x - 8<br> solve for x
OverLord2011 [107]

Answer:

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

Add 10 to both sides.

1.3x = 0.8x + 2

Subtract 0.8x from both sides.

0.5x = 2

Divide by 0.5.

x = 4.

Proof:

1.3x - 10 = 0.8x - 8

1.3(4) - 10 = 0.8(4) - 8

5.2 - 10 = 3.2 - 8

-4.8 = -4.8

Find the size of each interior angle of a regular hexagon
Serhud [2]

Answer:

Each interior angle = 180° -60° = 120°

Step-by-step explanation: We know that the three angles in a triangle, add up to 180°, and all the three angles are 60° in an equilateral triangle. The total number of angles of an enclosed space is 180° (n-2) where in is the number of sides.
A hexagon has six sides, so: s= 180° (6-2)

s= 180° x 4

s= 720°

now since in a regular shape, each interior angle is equal. We just divide the total interior angle with a number of sides

6.

720° divided by 6 is equal to 120°
