Answer:

  161.8 cm²

Step-by-step explanation:

The given formula works if you have both legs of the triangle. Using the given information, a better formula is ...

  A = (1/2)ab·sin(C) . . . . C is the angle between sides 'a' and 'b'

  A = (1/2)(27.6 cm)(30 cm)sin(23°) ≈ 161.8 cm²

20) Write a division number story with an answer of 1/4.<br><br> Be sure to ask a question.
Rainbow [258]

Answer:

Story: <em>Mr. Lanre bought 8 apples for $2. What is the cost of each apple.</em>

Step-by-step explanation:

Given

Answer = \frac{1}{4}

Required

Write a division story

A division story could be:

Mr. Lanre bought 8 apples for $2. What is the cost of each apple.

Solving the above problem, we have:

Apples = 8

Total\ Cost =\$2

The cost of each is:

Each = \frac{Total\ Cost}{Apples}

Each = \frac{2}{8}

Simplify fraction

Each = \frac{1}{4}

A hiker at the top of a mountain spots his car back in the parking lot at the
mart [117]
<h2>Answer:</h2><h2>The angle of depression from the hiker to his car, Θ = 56.39 degrees</h2>

Step-by-step explanation:

A hiker at the top of a mountain spots his car back in the parking lot at the

bottom of the trail.  If the trail is 632 meters long and the mountain is 420

meters tall,

opposite side = 632 m

adjacent side = 420 m

Angle of depression, Θ = arctan (\frac{opposite}{adjacent} )

= arctan (\frac{632}{420} )

Θ = 56.39 degrees

Suppose you deposit $1200 into a savings account that compounds interest continuously at 3.9%. You left your money in the accoun
kodGreya [7K]

Answer: you would have $1772 at the end of 10 years.

Step-by-step explanation:

The formula for continuously compounded interest is

A = P x e (r x t)

Where

A represents the future value of the investment after t years.

P represents the present value or initial amount invested

r represents the interest rate

t represents the time in years for which the investment was made.

e is the mathematical constant approximated as 2.7183.

From the information given,

P = $1200

r = 3.9% = 3.9/100 = 0.039

t = 10 years

Therefore,

A = 1200 x 2.7183^(0.039 x 10)

A = 1200 x 2.7183^(0.39)

A = $1772 to the nearest dollar
