The time he spent running is 13.80 seconds.

<h3>How much time did he spend running?</h3>

The equation that can be used to represent the time he gets to the tree is:

Time he gets to the tree = (time of each spin x total spins) + time he spent running

21 = (6 x 1.2) + r

21 = 7.20 + r

r = 21 - 7.20

r = 13.80 seconds

Given : Total Number of Games the Team Played = 25

Given : Number of Games won by the Team = 17

\bf{The\;Percentage\;of\;Team\;Wins = (\frac{17}{25}) \times 100}

A tourist looks out from the observation deck of the Space Needle in Seattle. The deck is at a height of 520 ft. She sees her fr
WARRIOR [948]

Answer:

Last option 527.7 ft

Step-by-step explanation:

From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)

Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.

Sin ∠ACB = \frac{AB}{AC}

Now we apply sin rule sin 80.2 = \frac{520}{H}

.9854=\frac{520}{H}

H = \frac{520}{.9854} = 570 ft

So the tourist and her friend are 527.7 ft apart.

Answer:Mixed number = a whole number and a proper fraction, of the same sign.

Proper fraction = numerator smaller than denominator.

35 = 17 × 2 + 1 =>

35/2 =

(17 × 2 + 1) / 2 =

17 + 1/2 =
