The answer would be 17. It’s a 90° angle and if you do 90-73, you get 17.
the answer is b)-7 or it could be 5
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
Answer:
526.39 million
Step-by-step explanation:
The exponential equation can be written as ...
p(t) = 471.56(492.53/471.56)^(t/10)
Then p(25) ≈ 525.75 . . . . million
__
The closest answer choice is 526.39 million.

<em>Comment on the answer choice</em>
Reverse-engineering the answer, we find it was computed using the exponential equation ...
p(t) = 471.56e^(0.0044t)
p(25) = 471.56·1.116278 ≈ 526.39
The k factor in the exponent is <em>inappropriately rounded</em> from 0.004350903. You cannot use a 2-significant-figure constant to arrive at an accurate 5-significant-figure answer.
