Height of triangle = 1/2 height of rectangle = 1/2 (16) = 8
answer
8ft (first one)
B-8 would be the answer. This is because we are saying you have 8 less than something. So no matter what something is, we are taking away 8 from it. Since our something is unknown, we use our variable 'b' in its place, and subtract 8, giving us b-8.<span />
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
A number rounded to the nearest 10000, means that the last four digits of that number (on the left of the decimal point) are 0.
<span>However, if the fourth-last digit to the left of the decimal point is 5 or greater, the number to the left of that is rounded to 1 number higher. For example, if you were rounding 145293 to the nearest 10000, it would be 150000.
However, the </span>fourth-last digit to the left of the decimal point in this case is 1.
Therefore, <span> 21000 rounded to the nearest 10000 is 20000.

It would be B or 1,625 because percentages are going to always involve multiplication. if I'm wanting to find a percentage you do .25 times 6,500 which leaves you with 1,625.
