Answer:

52.09

Step-by-step explanation:

Follow the acronym PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) for order of operations problems.

1. Solve what is in parentheses. (9 - 7) = 2

48 ÷ 23 + 25 (9 - 7) = 48 ÷ 23 + 25 × 2

2. Divide. 48 ÷ 23 = 2.09

2.09 + 25 × 2

3. Multiply. 25 × 2 = 50

2.09 + 50

4. Add. 2.09 + 50 = 52.0

I know that 52.09 wasn't one of the options listed, but it is the exact answer. If you must choose one of those options, choose 50, since it is the closest.

What is the height of the building pictured below if its shadow is 100 ft. long?

Yeah.. baby, do the SOH CAH TOA with the hula hoop

$\bf 
sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
$

so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so $\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}$

solve for "h"

A runner compared how long it took him to run 200 meters to the record time held by a friend. In his first heat, his time was 2.

Rasek [7]

Answer: it took him 0.075 seconds lesser

Step-by-step explanation:

In his first heat, his time was 2.45 seconds greater than his friend's record time. In his second heat, his time was 2 3/8 seconds greater than his friend's record time. Converting 2 3/8 seconds to decimal, it becomes 2.375 seconds

Therefore, he was fastest in the second heat.

The difference between the time he used to run in the second heat than in the first heat is

2.45 - 2.375 = 0.075 seconds
