20% i think, since its 1/5 of 300 is 60
Answer:
x = 10 yd
Explanation:
These triangles are based on proportions. 12 yd is proportional to 18 yd, and <em>x </em>yd to 15 yd. We want to find <em>x</em>. We'll use the rule of three to calculate the unknown number.
12/18 = x/15
x = (12 · 15)/18
x = 10 yd (10 yards from the hut to the gold coins)
Answer:
1590.4 square ft
Step-by-step explanation:
r=30 so you need to multiply that by 25% (30*.25=7.5)
30-7.5=22.5
A= pi(r)^2
A=pi*(22.5)^2
A=506.25pi
A=1590.43 or 1590.4 (to the nearest tenth)
If the diameter is 24, the radius must be 12
√(3x²) = 12
<span>3x² = 144 </span>
<span>x² = 48 </span>
<span>. . . . ._ </span>
<span>x = 4√3
</span>Each edge of the cube is twice that or <span>8√ 3
</span>
Hope this helps
