Contact [7]

Answer:

The answer to your question is: height = 99.41 feet.

Step-by-step explanation:

Data

distance = 96 feet away from a building

angle = 46

height = ?

Process

Here, we have a right triangle, we know the angle and the adjacent leg, so let's use the tangent to find the height.

tan Ф = opposite leg / adjacent leg

opposite leg = height = adjacent leg x tan Ф

height = 96 x tan 46

height = 96 x 1.035

height = 99.41 feet.

  • <em>Answer:</em>

<em>cousin</em>

<em>1/20 inches</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>cousin</em>

<em>21 4/5 = (21×5+4)/5 = 109/5</em>

<em>friend</em>

<em>21 3/4 = (21×4+3)/4 = 78/4</em>

<em />

<em>lcm(4 ; 5) = 20</em>

<em>⁴⁾109/5 = 436/20 (cousin)</em>

<em>⁵⁾87/4 = 435/20 (friend)</em>

<em>436/20 > 435/20</em>

<em>cousin > friend</em>

<em>436/20 - 435/20 = 1/20 inches longer (cousin)</em>

<em>Good luck !</em>

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. if the decimal is being moved to the left, the exponent will be positive. all i really did was subtract the numbers without the exponents. but this is useless right now so the answer is: 2.1*10^7
Basically: 2.1 times 10 to the power of 7
