Answer:
7
Step-by-step explanation:
24^2+b^2=25^2
576+b^2=625
<u>-576</u> <u>-576</u>
b^2=49
√b=√49
b=7
An octagon has eight sides
Answer:
3. 6
Step-by-step explanation:
X - y = 4 ( Equation 1 )
X + y =8 ( Equation 2 )
equation 1 + equation 2
; 2x = 12
x = 12÷2
x =6
hope it helps ☺️
Your answer would be (D) because 8*8 is 64. Then you multiply 64 by 6 since their are 6 sides to cube, and 384 mm³ is what you would get. Hope this helps!
A) This is a repeating decimal which means it is possible to write it in the form p/q where p & q are integers and q is nonzero. So we can rule out choice A.
B) Similar to the answer choice above, we have another repeating decimal. So we can rule out choice B.
C) This is a terminating decimal. It does not go on forever. We can write this as a fraction (0.7 = 7/10). So we can rule out choice C.
D) This is also terminating so it seems like your teacher made a typo. What I'm thinking is that the 3.14 was meant to be a decimal that goes on forever without a pattern. This is a well known number called pi. I'm assuming that's what your teacher was going for.
So I'd go with choice D as the answer.
