If you must, try writing the fraction (1/2) eleven times and then write the addition operator ( " + " ) between each such fraction: (1/2) + (1/2) + ....... + (1/2) + (1/2). You'll see that adding 11 of these fractions (1/2) together produces a sum of 5 1/2.

Well you add 1/2 + 1/2 = 1 in
(1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + 1/2=
2 half inches per parentheses pairs which is 5 plus the 1/2 inch
( 11 half inches shown above)

In the right triangle ABC shown, c=17ft and angle A=30 degrees Determine side a

jekas [21]

Using relations in a right triangle, considering c as the hypotenuse, we have that the length of side A is: $a = 8.5\sqrt{3}$

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

From the information given, we can build the following relation:

cos(A) = a/c.

$\frac{\sqrt{3}}{2} = \frac{a}{17}$

$a = \frac{17\sqrt{3}}{2}$

$a = 8.5\sqrt{3}$

A geologist studying the depths of water in a mountain lake finds that it has changed from 8,300 ft to 8,881 ft over a period of

grigory [225]

Answer:

7.0%

Step-by-step explanation:

Here, we want to get the value of the percentage increase

mathematically, we have the formula for this as follows ;

(new value - old value/old value * 100%

from the question, old value is 8,300 ft and the new value is 8,881 ft

So we have the percentage increase as follows;

(8,881 - 8,300)/8,300 * 100%

= 7.0%
