Answer:
Step-by-step explanation:
The surface area of a rectangular prism has six sides so you must find the sum of the areas of all sides.
A=2xy+2xz+2yz
A=2(xy+xz+yz) you have x,y,z as 3,2,4 so
A=2(3(2)+3(4)+2(4))
A=2(6+12+8)
A=2(26)
A=52 cm^2
We know that
a) find <span>the ratio of the perimeters
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3
b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure
the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9
the answer Part b) is
169/9
the complete answer is
13/3 and 169/9
Answer: 300 percent
Step-by-step explanation:
Where: 15 is the old value and 60 is the new value. In this case we have a positive change (increase) of 300 percent because the new value is greater than the old value.
Your answer is gonna be C.
