Answer:

70cm

Step-by-step explanation:

Area of triangle:              (5.8x4)/2=11.6

Area of big rectangle:     8x5.8=46.4

Area of small rectangle:  2.4x5=12

12+46.4+11.6=70

 - The<span> hot air balloon is at an altitude of 240 feet.
 - It descends at 30 feet per minute.

 2. Therefore, you have:

 x: the time in minutes.
 y: the altitute in feet.

 3. Keeping all this information on mind, you can write the following equation:

 y=240-30x

 4. Therefore, as you can see, the answer is:

Answer:

  83 m

Step-by-step explanation:

The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...

  8.26(10 m) = 82.6 m ≈ 83 m

_____

The distance formula will tell you the distances are ...

  AC = √(3² +1²) = √10

  BD = √(5² +1²) = √26

The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

What is the value of x in the equation 7(4x+1)−3x=5x−13?
Citrus2011 [14]

Answer:

x = -1

Step-by-step explanation:

7(4x+1)−3x=5x−13

Distribute

28x +7 -3x = 5x -13

Combine like terms

25x+7 = 5x-13

Subtract 5x from each side

25x-5x +7 = -13

20x +7 = -13

Subtract 7 from each side

20x+7-7 = -13-7

20x = -20

Divide by 20

20x/20 = -20/20

x = -1
