Answer:
Can you describe this question
Step-by-step explanation:
There are 81 girls to every 72 boys in total, which can be represented by 81/72, which put into decimal form, is 1.125. If you then take the number of boys in the group, 16, and multiply it by this number (because the problem states that the ratio is constant) you can find the number of girls in the group.
16*1.125=18
So there are 18 girls in a group with 16 boys.
The answer I think if I’m correct is Minnie
You would have 38 quarters=$9.50 and you would have 12 nickels=$.60, which means that you would have a total of $9.50+$.60=$10.10 and then 38+12=50 coins.
Answer:
A
Step-by-step explanation:
a hyperbola is used in the form
(x-h)^2/a^2 - (y-k)^2/b^2
in this case h=1 k=2 a=6 b=8
since the x part comes first, use y = +-(b/a)(x-h) + k to find the asymptotes
we get y = +-(4/3)(x-1) + 2
multiply out the 4/3 to get
for +: (4x-4)/3 + 2
for -: (-4x+4)/3 + 2
change 2 to 6/3 and combine:
for +: 4x+2/3
for -: (-4x+10)/3
