Answer:
check explanation
Step-by-step explanation:
so you must find the missing leg. pythagorean theorem is a^2 + b^2 = c
find C and that number, use to find the area of the triangle.
to find area of a triangle, you use this formula- area=1/2bh
Answer:
x=-2
Step-by-step explanation:
11x-21=7x-29
11x-7x=-29+21
4x=-8
x=-2
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
To solve for the width and the length of the pool, you will use the formula for finding the volume of a rectangular prism. You will represent the length and the width of the pool in terms of w, the width.
Please see the attached picture for the work.
The width of the pool is 20 feet.
The length of the pool is 3 x 20 ft or 60 feet.
