Answer:
The replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.
Step-by-step explanation:
Given that a pyramid art installation has a surface area of 24 m2, and an artist creates replicas with scale factors of 1/8, 1/10, and 1/12, to determine what is the surface area of each replica, the following calculation has to be done:
24 x 1/8 = 3
24 x 1/10 = 2.4
24 x 1/12 = 2
Therefore, the replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.
Answer:
True
Step-by-step explanation:
Double blind means both sides are unaware of the groups
Step-by-step explanation:
5t -(18x4)=-36
5t-72=-36
5t=-36+72
5t=36
t=36/5
<span> −2.3(x−1.2)=−9.66 remove the brackets by multiplying
-2.3x+2.76=-9.66 collect the like terms
-2.3x=-9.66-2.76
-2.3x=-12.42 divide both sides by -2.3 to find x
x=5.4</span>
