It took a boat 4 hours to travel downstream 120 miles. Upstream, the same trip took 6 hours. Find the rate of the current and the speed of the boat in still water.

Answers

Answer:

25 mph, 5 mph

Step-by-step explanation:

Speed of the boat = xSpeed of the current = y

Travel downstream, speed is:

x + y = 120/4 = 30

Travel upstream, speed is:

x - y = 120/6 = 20

Add up the equations:

x + y + x - y = 30 + 202x = 50x = 25

Find y:

y = 25 - 20 = 5

Speed of the boat is 25 mph

Speed of the current is 5 mph

Answers

Step-by-step explanation:

for the demoninator to get to 4 to 12 u times by 3 (4,8,12) so you times the numerator by 3, 3 times 3= 9

so its 9/12

for 6 to get to 12, you times by 2, (6,12) so times the numerator by 2, 1 times 2 is 2

9/12-6/12= 3/12

A traffic helicopter descends 154 meters to be 313 meters above the ground. What was the original height of the​ helicopter? Let h be the original height of the helicopter. What is a subtraction equation that models the​ problem?

Answers

Answer:

H= 347m + 182m

H = 529 m

so the original height of the helicopter is 529 meters

Step-by-step explanation:

Answer:

467 feet off the ground

Step-by-step explanation:

If the helicopter descends 154 meters, this means the helicopters height drops 154 meters from its original height. If the helicopters current elevation is 313 meters, to find its original height, we can inverse the equation. So instead of subtraction, use addition. 154+313=467 meters is the original elevation.

Help with my math i will mark brainliest

Answers

Answer:

D

Step-by-step explanation:

step 1: find the slope

slope is 2/-4 = -1/2

then plug in the value for x to y, you get +1 for the y intercept

then it becomes y=-1/2x + 1

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

Answer:

[tex]y=-\frac{1}{2} x+1[/tex]

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

SO

[tex]\frac{y_{1}- y_{2}}{x_{1}- x_{2}} \\\\=\frac{2-0}{-2-2}[/tex]

[tex]=-\frac{1}{2}[/tex] this is your slope

so now your equation is [tex]y=-\frac{1}{2} x[/tex] but it isnt done yet if we plug in one of the points we will find the y- intercept.

SO we find our y-intercept is 1 so that makes our equation [tex]y=-\frac{1}{2} x+1[/tex]

Hope this helps!

The area of the square and rectangle are equal. If the side of the square is 50 cm, and the breadth (width) of the rectangle is 10 cm, find the length and perimeter of the rectangle.

Answers

The length would be 250cm and the perimeter would be 520cm

Explanation

So if one side of the square is 50 all are, therefore 50 x 50 is 2,500 and the area of square and rectangle are equal so you would divide 2500 by 10 and get 250.

2. Write a division equation to represent this situation.

3. How much does the trip cost? Write your answer without the dollar sign.

Answer:

600 dollars

Step-by-step explanation:

I'm not sure of 1 and 2. 2/5 = 240 dollars so 1/5 is 120 dollars then 120 times 5 = 600 dollars

1/5 = 120 times 5 = 600 dollars240/2 = 120 dollars600 dollars
