2/4 = 1/2
2/6 = 1/3
4/12 = 1/3
8/24 = 1/3
If you need help on how to solve these, you can contact me directly
s = lw + 2wh
We can take the 'w' out of the right side of the equation:
s = w(l + 2h)
Divide both sides by (l + 2h)
w =
Good luck!
Answer:
50.18°
Step-by-step explanation:
∠BAD = ∠BAC +∠CAD
102° = (8x+17)° +(9x+11)° . . . . . substitute given values
102 = 17x +28 . . . . . . . . . . simplify, divide by degrees
x = (102 -28)/17 = 74/17 . . . . . solve for x
Then the angle of interest is ...
∠CAD = (9x +11)° = (9(74/17) +11)° = 50 3/17°
∠CAD ≈ 50.18°
Answer:
The explicit formula of the given AP is a(n) = 7 + 7 n
And the term a (13) = 98
Step-by-step explanation:
Here, the given sequence is : 14, 28 , 42, 56 ,....
First Term (a) = 14
Second term = 28
Now, the Common difference (d) = Second term - First Term
= 28 - 14 = 14
Now, the formula for nth term in an AP is : a(n) = a + (n-1)d
So, here, the nth term of the sequence is given as:
a(n) = 14 + (n-1) 7
= 14 + 7 n - 7 = 7 + 7 n
or, a(n) = 7 + 7 n ......... (1)
or, The explicit formula of the given AP is a(n) = 7 + 7 n
Now, for evaluating a (13) put n = 13 in (1)
⇒ a(13) = 7 + 7 (13) = 7 + 91 = 98
or, a (13) = 98
Yea I don’t knowing how to help you please explain
