Lets go ahead and calculate the area of each side; added together, this will give us the full surface area. First the base, which is 9 by 9 and a square. This means its area is 9*9, which equals 81. Next the triangles, which are all the same, so we only have to do it once and then add it 4 times at the end. The area of a triangle is (1/2)bh, so (1/2)(9)(7) = 31.5.
Finally, we just need to add the areas up.
81 + 31.5 + 31.5 + 31.5 + 31.5 = 81 + 4(31.5)
81 + 126 = 207 units^2
Answer:
(12,3) and (20,5)
Step-by-step explanation:
When using the direct variation equation we can check these by division and we get .25 for the answer of both.
3/12 and 5/20
Nelson needs to save $114 and Jamie needs $108.
Answer:
<h2><u>
x=−3/7</u></h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
34x=27x−3
Step 1: Subtract 27x from both sides.
34x−27x=27x−3−27x
7x=−3
Step 2: Divide both sides by 7.
7x\7=−3\7
x=−3/7
