A= 3631.68
Step-by-step explanation:
the formula to find the surface area is A=2πrh+2πr^2 so when you substitute all your radius values and height values, you get approximately 3631.68
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
Answer:
x = 3, y = 1
Step-by-step explanation:
Given the 2 equations
y = - x + 3 → (1)
y = 2x - 5 → (2)
Substitute y = 2x - 5 into (1)
2x - 5 = - x + 3
Multiply through by 3 to clear the fraction
6x - 15 = - 2x + 9 ( add 2x to both sides )
8x - 15 = 9 ( add 15 to both sides )
8x = 24 ( divide both sides by 8 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 2(3) - 5 = 6 - 5 = 1
Thus x = 3 and y = 1
