Answer:
Step-by-step explanation:
I believe the only way to solve this is by Heron's Formula.
Add up all the sides and divide by 2 to get the semi-perimeter:
113+100+86 = 299
299/2 = 149.5
Now fill in the rest, which looks like this:
where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:
which simplifies to
which simplifies further to
which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).
Answer:
Step-by-step explanation:
Plot the point (4, -1) in the 4th Quadrant.
The slope (-3/4) tells us what to do next:
With your pencil point initially on (4, -1), move it 4 units to the right, to (8, -1).
With your point initially on (8, -10, move it down 3 units, to (8, -4). Plot (darken) (8, -4).
Draw a line through (4, -1) AND (8, -4)
To obtain 58 percent of 18 multiply 18 by 0.58, because 58 percent is equal to 58/100. That said, your result rounded to two decimals is 10.44.
This answers what is 58% of 18. If you have a currency, such as in the case of 18 dollars, proceed as outlined in the example right below.
Answer:
c = 289
Step-by-step explanation:
Given
x² + 34x
To complete the square
add ( half the coefficient of the x- term )² to x² + 34x
= x² + 2(17)x + 17²
= x² + 34x + 289 ( with c = 289 )
= (x + 17)² ← perfect square
Answer: $100.70
Step-by-step explanation: 6% is equal to 0.06, so you can add multiply the price of the item by 1.06 because that is the base cost plus the tax. Then you get $100.70.
