If you make the numbers into a ratio, it will be easier to find the answer.
There are 68 blue squares for the 4 green squares in the quilt.
68:4, or 68/4
If we do the division of the ratio, 68/4, we end up with 17.
Now, we multiply that by the 11 green squares of the new quilt.
17 x 11 = 187
Answer:
a=25
Step-by-step explanation:
Solve by subtracting 3 from both sides.
a/5=5
Multiply both sides by 5.
a=25
Answer:
55
121
Step-by-step explanation:
I divided 22 by 2 to get how many pirates for every 1 ship got 11 then multiplied 5 and 11. Then 11 and 11 and got my answers.
Without knowing what Juan's exact steps were, it's hard to say what he did wrong. The least you could say is that his solution is simply not correct.
4 sin²(<em>θ</em>) - 1 = 0
==> sin²(<em>θ</em>) = 1/4
==> sin(<em>θ</em>) = ±1/√2
==> <em>θ</em> = <em>π</em>/4, 3<em>π</em>/4, 5<em>π</em>/4, 7<em>π</em>/4
