Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
Convert 3 1/3 into a improper fraction:
= 10/3
Then flip the other fraction around and multiply them together:
1/3 -> 3/1
(10*3)/(3*1) = 30/3 = (30/3)/(3/3) = 10/1 = 10
The answer is 10
2.8 multiplied by 2.8 to find the surface area of the base which is 7.84
4*1/2*2.8*5.5 to find the surface area of all four triangular faces which is 30.8
Plus them together 7.84 plus 30.8 which is 38.64
Answer:
The answer is 7 1/24
Step-by-step explanation:
27/8 + 11/3
I multipled 27/8 by 3/3 (needed the 8 to become 24)
I multiplied 11/3 by 8/8 (needed the 3 to become 24)
We get:
81/24 + 88/24
Then you add
169/24
Simplify
7 1/24
