Suppose a rescue helicopter is 700 feet above sea level descends 300 feet to search for debris or any other signs of a submarine

in trouble. When the captain does not see anything, he ascends 200 feet and stays at that altitude while he tries to get a radio signal from the submarine. A few moments later he speaks to the captain and is informed that the submarine is 122 feet below sea level. How far is the helicopter from the submarine?

Answer:

The helicopter is 722 feet from the submarine.

Step-by-step explanation:

700 - 300 = 400

400 + 200 = 600

600 - 122 = 722

700-300+200=600
600+122=722

You will use 220ft of fencing to fence a rectangular plot of land. The length is 20 more than the width. What are the dimensions
PSYCHO15rus [73]
Set up the following equations:

L + W = 110
L - W = 20

110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.

We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

2L = 130

Divide both sides by 2 to get L by itself:

L = 65

The length of the rectangle is 65 feet.

Plug this value into the second equation:

65 - W = 20

Add W to both sides:

65 = 20 + W

Subtract 20 from both sides:

45 = W

The width of the rectangle is 45 feet.

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second wi
Alenkasestr [34]

195 students voted for eagle in the election

What is ratio?

Ratio means expressing the a figure as a fraction of total figure, in the case of falcon, the number of students that voted for falcon is seen as 5 whereas the total number of students that voted is 8 whereas for eagle, the total number of students that voted for eagle is 1 compared to 3 which represents the total number of votes cast.

In a bid to determine the number of students that voted eagle in the election, we would simply multiply total votes of 536 by 1/3

votes for eagle=1/3*586

votes for eagle=195 votes

We have rounded to the nearest whole number since number of votes cannot be fractional

What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%
bagirrra123 [75]

Beth purchased $21.25 worth of groceries. The sales tax rate is 7.5%. What was her total bill?

The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.


Back to your question:

What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%

The tax is calculated by 0.0575 * 45 = 2.5875 or $2.59. So the total bill is the cost of items purchased plus tax, which is $45 + $2.59 = $47.59

Hope this helped! Good luck!
