Hello from MrBillDoesMath!
Answer:
The fourth choice, b = +\- sqrt( sg + a^2)
Discussion:
s = (b^2 - a^2)/g => multiply both sides by "g"
sg = b^2 - a^2 => add a^2 to both sides
sg + a^2 = b^2 => take the square root of each side
b = +\- sqrt( sg + a^2)
which is the fourth choice.
Thank you,
MrB
Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
x = 30cm
length = 30 cm
breadth = 
cm
Answer:
620
Step-by-step explanation:
I might be wrong.
But based on the question both burgers are sold on a Wednesday so the question is asking how many cheeseburgers were sold on a Wednesday (which is the same day they both were sold) so I think you subtract.
so 685-65.

Answer:
Kenny will get $16 change from $100 if he buys a book of 8.
Step-by-step explanation:
Given cost of each ticket of the dinosaurs now exhibit = $10.50.
Total number of tickets = 8 tickets.
Total amount Kenny has to buy tickets = $100.
He need to buy only 8 tickets.
Total cost of 8 tickets = cost of one ticket × total number of tickets
= 10.50 × 8
= $84.
Therefore cost of all 8 tickets is $84.
Kenny would left money = 100 - 84 = $16.
<h3>Therefore, Kenny will get $16 change from $100 if he buys a book of 8.</h3>
