Use the pythagorean theorem. It would be set up as
a^2 + 3.7^2 = 4.0^2
Answer:
196 
Step-by-step explanation:
Surface are of 2 rectangles = 2(2*4) = 16
surface are of the base rectangle = 4*3 = 12
Area of tow triangles =2( 
* 2* 2)= 4
total = 16+12+4
= 196
Answer:
Step-by-step explanation:
<u>Let the numbers be x, y and z</u>
- x + y + z = 24
- 2y = z + 2
- z = x + y
<u>Solving by substitution:</u>
- x + y + z = z + z = 24
- 2z = 24
- z = 12
- 2y = z + 2
- 2y = 12 + 2
- 2y = 14
- y = 7
- z = x + y
- x = z - y
- x = 12 - 7 = 5
<u>The answer:</u>
Answer: not all
Step-by-step explanation:
The sum of their speeds is 380 miles per hour. The difference of their speeds is 30 miles per hour. Then the faster plane is traveling at
.. (380 +30)/2 = 205 miles per hour
The slower plane's speed is 30 miles per hour less, so it is traveling at
.. 205 mph -30 mph = 175 miles per hour
