Ariana spent a quarter of her allowance on sweets and she put one third of the remainder in her piggy bank. If she had twenty dollars left, what was her allowance
Answers
Answer:
$40
Step-by-step explanation:
Ariana spent a quarter of her allowance
1 - 1/4 = 3/4 was left
put one third of the remainder in her piggy bank
1/3 * 3/4 = 1/4
She spent 1/4 and piggy banked 1/4
so the $20 she had left was half her allowance.
allowance was $40
Ariana gets a very large allowance!

let the diagonal be x
⇒54²+72²=x²
⇒8100=x²
x=90meters
now, as we know that each angle in a rectangle is right angle.
thus we have a right angled triangle.
now, we can apply pythagoras theorum.
a^2 = 54^2 + 72^2
= 2916 + 5184
=8100
thus, a^2 = 8100
thus, a = 90.
Thus the diagonal is 90metres.

Probability helps us to know the chances of an event occurring. The probability that all four pennies will be tails is (1/16).
What is Probability?
Probability helps us to know the chances of an event occurring.
The probability of a penny getting a tail is 0.5 or (1/2), therefore, the probability of four penny getting a tail can be written as,
Hence, the probability that all four pennies will be tails is (1/16).

by 10.5 inches. The second box measures 9 inches by 5.5
inches by 11.75 inches. Which box required more material to
make?
Answers
Total surface area of second box = 2(9 * 5.5) + 2(9 * 11.75) + 2(5.5 * 11.75) = 2(49.5) + 2(105.75) + 2(64.625) = 99 + 211.5 + 129.25 = 439.75 sq. ins
Hence, the second box requires more material to make.
