You are given Richard’s piano practice for 3 piano solos. Every piano sol
he makes takes 5/12 hour. You are asked to find how long Richard is going to
practice his piano solo. So we have for every 1 piano solo he makes this is
equal to 5/12 hours. This can be best represented by ratio and proportion.
1 piano solo/(5/12 hour) = 3 piano solo/(number of hours)
Number of hours = 3 piano solo/ (1 piano solo/5/12 hours)
<u>Number of hours = 5/4 hours or 1.25 hours.</u>
Finding the sum for y in the equation 4x-2y< 0
so 4x - 2y = 0
4x - 2y - 4x would equal 0 - 4x
-2y = -4x
-2y divided by -2 equals -4x / -2
That means y=2x
A cross section is the shape you get when you cut straight through an object Like a prism so
you will get a triangle example:
In geometry it is the shape made when a solid is cut through by a plane. The cross section of a circular cylinder is a circle or a cross section of a pyramid is a rectangle. A two dimensional figure like a rectangle has two dimensions length and width. A three dimensional figure like a building has three dimensions length width and height.
The turtle`s speed:
v t = 12 miles / hour = /*5,280
= 63,360 ft / hour = / : 3
= 21,120 yards / hour = / : 60
= 352 yards / minute
The boy`s speed:
v b = 4.4 ft/ s = / * 60/3
= 4.4 * 20 yards / minuet = 88 yards / minute
v t : v b = 352 : 88 = 4
The turtle swims 4 times faster than the boy.
