Answer:
so 20*5=100 and a percent is out of 100
so we just multiply 18*5 which equals
90 so 18/20=90%
we could also figure this out because if we simplify we get
9/10 which is also 90%
Hope This Helps!!!
Answer:
SA= 902.88 yd²
V = 1386.24 yd³
Step-by-step explanation:
Surface area
Since the bases are right triangles, you need to find the base of the triangle. Use Pythagorean theorem as you are given the hypotenuse and one leg.
19² = 15.2² + b²
361 = 231.04 + b²
Subtract 231.04 from both sides
b² = 129.96
Root that
b = 11.4
Now that you have the base, find the areas of the triangles and rectangles.
<em>Triangles</em> - (15.2*11.4)1/2 (2)
15.2*11.4 = 173.28
<em>Rectangles </em>- (15.2)(16) = 243.2
(16)(11.4) = 182.4
(16)(19) = 304
Add them all together and the SA equals 902.88 yd²
Volume
V = Bh
V = 1/2(15.2)(11.4)(16)
V = 1/2 (2772.48)
V = 1386.24 yd³
6^3x+2=216
The steps on solving this problem is first write MDAS which means mutliplication is first so first you multiply 6^3x+2 after your done you get 18^x+2=216
and thats how you do it. (I hope that help cause I showed my teacher this question she kinda helped me with it..)
What do you mean " Inst it the definition?
Answer:
this probably isn't right, but with an educated guess it's probably the third answer.
