Answer:

Option A. $1713.98

Step-by-step explanation:

You have to calculate your parents' monthly fixed expenses by the given expenses list.

Rent = $998.50

Groceries ( bi-weekly ) = $195.40 Monthly groceries = (195.40×2)

Charge card = $258.90

Cell phone = $65.78

Name brand Khakis for work (store brand optional ) = $34.95

Total expenses are 998.50 + (195.40×2) + 258.90 + 65.78

= $1713.98

Option A. $1713.98

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle

taurus [48]

Answer:

AC = 10sin(40°)

Explanation:

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

These functions are as follows:

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

Now, in the given diagram:

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

Based on these givens, we will use the sin(θ) function

Therefore:

$sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)$

Answer:

The correct answer is C. 4.7%

Correct statement and question:

A marine biologist is setting up a net 6 feet below the surface of the water. Each foot of the water screens out 40% of the light coming from the surface. Which of the following is the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent?

0.4%

1.0%

4.7%

7.8%

Source: brainly.com/question/4136163

Step-by-step explanation:

1. Let's review all the information given to us to answer the question correctly:

Depth of the net = 6 feet below the surface of the water

Each foot of the water screens out 40% of the light coming from the surface.

2. Which is the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent?

After one feet: 100 - 40 = 60%

After two feet = 60 - 0.4 * 60 = 60 - 24 = 36

After three feet = 36 - 0.4 * 36 = 36 - 14.4 = 21.6

After four feet = 21.6 - 0.4 * 21.6 = 21.6 - 8.64 = 12.96

After five feet = 12.96 - 0.4 * 12.96 = 12.96 - 5.18 = 7.78

After six feet = 7.78 - 0.4 * 7.78 = 7.78 - 3.11 = 4.67 = 4.7 (Rounding to the nearest tenth)

The correct answer is C. 4.7%
