Answer:
224
Step-by-step explanation:
<u>Base:</u>
A = Bh
A = 8(8) = 64
<u>Sides:</u>
A = 1/2 Bh
A = 1/2 8(10)
A = 40
<u>Then you do 40(4) because there are 4 sides:</u>
40 (4) = 160
<u>Then you add up the base and the sides:</u>
160 + 64 = 224
(I think this is the right answer)
There are total 80 dimes in the jar. B/c...
n+d=200 = n=200-d
0.05n+0.1d=$14.00
0.05(200-d)+0.1d=$14.00
10-0.05d+0.1d=$14.00
10+0.05d=$14.00
-10 -10
0.05d=$4.00
0.05d/0.05=$4.00/0.05
d=80
Answer:
A triangular bike path
Step-by-step explanation:
bcos by Pythagoras theorem if we do the square of 5 and 12 and that is equal to 13 square. hence this real right angle triangle and others are not.
-13 = 4(5x - 1) - 11x
-13 = 20x - 4 - 11x
-9 = 9x
-1 = x
