Step-by-step explanation:
5x+5=3x+27
Answer/Step-by-step explanation:
Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².
We would use the above knowledge to solve the questions given as follows:
✔️The first pair similar of shapes:
Missing area = x cm²
Therefore,
x/9 = 8²/4²
x/9 = 64/16
x/9 = 4
Cross multiply
x = 4 × 9
x = 36 cm²
✔️The second pair similar of shapes:
Missing area = x cm²
Therefore,
x/240 = 8²/32²
x/240 = 64/1,024
Cross multiply
x*1,024 = 64*240
x*1,024 = 15,360
Divide both sides by 1,024
x = 15,360/1,024
x = 15 cm²
✔️The third pair similar of shapes:
Missing area = x cm²
Therefore,
x/40 = 3²/2²
x/40 = 9/4
Cross multiply
x*4 = 9*40
x*4 = 360
Divide both sides by 4
x = 360/4
x = 90 cm²
2+3x=62
3x=60
x=20
Hope this helps! Brainliest? :D
b. How many canse will Lydia and Adam use total?
(a). 9 layers
(b). 285
In the question,
The Square Pyramid is needed to be made from the cans.
The base of the pyramid has = 81 cans
So,
Side of the Square = s
So,
Therefore, the number of cans on one side of the square base = 9 cans
So,
The number of cans will be reducing by 1 in each layer upto the point we are left with only 1 can in the top.
So,
1st layer = 9 cans
2nd layer = 8 cans
3rd layer = 7 cans
4th layer = 6 cans
5th layer = 5 cans
6th layer = 4 cans
7th layer = 3 cans
8th layer = 2 cans
9th layer = 1 can
Number of layers are = 9
(b).
Total number of cans used by Lydia and Adam will be,
Sum of number of cans in all the layers.
Therefore, the number of cans = 285
