Answer:
is this the right question please??
80% is the same as 4/5, so 4/5 of the class= 20. That means that if there was a picture, 4 parts would be shaded, and 1 would not. 1/4 of 20 is 5, so 1 part= 5 people. 5 x 5 = 25. 25 is the answer. :)
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!
Answer:
$74.41
Step-by-step explanation:
x = Amount of money Sylvia had in her account
Amount of money spent at the Grocery Store= $25.89
Remaining Amount of money after Grocery = $48.52
Hence, By adding the two amount above we get the amount Sylvia had in her account before grocery;
x = $25.89 + $48.52
x = $74.41
