8×1+5×(1/10)+9×(1/1000)
8+5×(.1)+9×(.001)
8+.5+.009
Answer is 8.509
First you should write what you know since we don't know how many helmets we will use x
helmets - 5(x)
bats - 3(6x)
then write out the equation
5(x)+3(6x)=4600
then solve so first multiple 5 times x and multiply 3 and 6x
5x+18x=4600
then combine like terms which are 5x and 18x
23x=4600
then divide both sides by 23
x=200
200is the number of helmets and since there are six times the bats as helmets you multiply that by six and get
helmets=200
bats=1200
To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
Answer: sometimes, there are a lot of rectangles that are composite shapes so that could work. also, most composite shapes have two dimensions.
