Answer:
1/3 of the students
Step-by-step explanation:
4/12 of the students wins the small prize
so, 8/12 of the students will not get a small prize
1/2 of 8/12 = 4/12 = 1/3
1/3 of the students will get the certificate.
Answer:
subtract 5 , m=(-15)
Step-by-step explanation:
15-5
=10
n:
5-10
=(-5)
m:
(-5)-10
=(-15)

The surface areas of similar solids is proportional to the square of their sides
<span>since the ratio of sides is 1 : 3 </span>
<span>their surface areas have the ratio 1</span>²<span>: 3</span>²<span> or 1:9 </span>
<span>so the surface area is 9(10.4) or 93.6 </span>
<span>or </span>
<span>original width = x </span>
<span>original length = y </span>
<span>original heigt = z </span>
<span>original surface area = 2(xy) + 2(xz) + 2(yz) </span>
<span>= 2(xy + xz + yz) </span>
<span>new width = 3x </span>
<span>new length = 3y </span>
<span>new height = 3z </span>
<span>new surface area = 2(9xy) + 2(9xz) + 2(9yz) </span>
<span>= 18(xy + xz + yz) </span>
<span>ratio of new to old = 18(xy + xz + yz) : 2(xy + xz + yz) </span>
<span>= 9:1</span>
