You would set this up as Part÷Whole=Percent÷100
Part=117
Whole= X
Percent=78
117÷X=78÷100
Set these up as fractions and cross multiply. You will get 117×100=78X
117×100=11,700
Divide both sides by 78 and you get x=150

Answer:
The geometric mean of 2 and 8 comes out to equal 4.
Step-by-step explanation:
Answer:
82 cm
Step-by-step explanation:
In rectangles diagonals are equal and bisect each other
AO = BO
5x + 1 = 4x + 9
Subtract 1 from both sides
5x = 4x + 9 -1
5x = 4x + 8
Subtract 4x from both the sides
5x - 4x = 8
x = 8
AO = 5x + 1
= 5*8 +1
= 40 + 1
AO= 41 cm
Diagonal = 2*41 = 82 cm
Answer:
rounded to the nearest 10: 680
rounded to the nearest 100: 700
Step-by-step explanation:
9 rounds up to 10 so it would go to 80
and 6 rounds up to 10 also so it goes to 700
brainilest maybe?
Answer:
9. Option D, 2(3x + 5) and 6x + 10
10. 9 + 3 (10÷2) - 5² = -1
Hope this helps!
