There are 233 feet of wood that are required, but we can only buy in lengths of 11 feet. Therefore, we have to take the ceiling of the division 233/11 because if you take less than what you need, you won't have enough, but if you take more than you need, but only the bare minimum of it, you will have enough without wasting money. Therefore, 233/11 = 21, but you have that extra couple feet left, so you need to buy an extra plank to get 22 planks of wood.

Answer:
Step-by-step explanation:
Two similar triangles.
10/26 = y/13
y = 5
x² = 13² - y² = 144
x = 12
Answer: y=
+2
Step-by-step explanation:
<em>This is y intercept form</em>
First you find the slope
Then you find the y intercept and plug it in t the equation y=mx+b

Answer: 5</h3>
=========================================================
One method is to plot the points P(3,6) and Q(7,3) on the same xy grid. Plot a third point R at (3,3). See the diagram below.
A right triangle forms in which we can find the legs PR = 3 and RQ = 4. The hypotenuse is found through the pythagorean theorem.
a^2+b^2=c^2
3^2+4^2 = c^2
9+16 = c^2
c^2 = 25
c = sqrt(25)
c = 5
This is the length of PQ
-----------------------------------
Or you can use the distance formula which is effectively using the pythagorean theorem just in a slightly different format (though it may not be obvious).
