Hey there! :)
Answer:
SA = 144 cm².
Step-by-step explanation:
Find the surface area by calculating the areas of each of the lateral sides and bases:
In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:
Bases:
A = 1/2(bh)
A = 1/2(4·3)
A = 1/2(12)
A = 6 cm².
There are two bases, so:
6 × 2 = 12 cm²
Find the areas of the lateral sides using A = l × w:
5 × 11 = 55 cm²
4 × 11 = 44 cm²
3 × 11 = 33 cm²
Add up all of the areas:
12 + 55 + 44 + 33 = 144 cm².
Answer:
A. The description represents an arithmetic sequence because the successive y-values have a common difference of 600
Step-by-step explanation:
The equation that this situation is describing would be

This would mean that this equation would be an arithmetic series
The fewest number of expressions is 3.
Answer:
5m
Step-by-step explanation:
Given data
Ratio of length to breadth is 5 : 3
hence in fraction form it is 5/3
the breadth of rectangle is 60m
let the length be x
So
5/3= x/3
cross multiply we have
5*3= 3x
15= 3x
divide both sides by 3
x= 15/3
x= 5m
Hence the length is 5m
Answer:
B or C
Step-by-step explanation:
if its refering to the answer of 11 × X then the answer is C, but if its not the answer might be B.
