Answer:
Step-by-step explanation:
4^3 * 4^4 = 4^(3+4) = 4^7
4^7/4^9 = 4^(7-9)
= 4^-2 = 1/4^2
So a absolute value is just the opposite of the value given, (unless it is a positive number) so you start on -12 and count 24 units to the right so it would make positive 12
Sarah was locked out of her apartment and the only way out is through a window three stories high 20 feet above the ground. She needed to borrow from one of her friends. There is a tree along the side of the house so she will need to put the ladder 15 feet from her apartment. How long does the ladder need to be to reach the apartment window?
Answer:
The difference between the largest and the smallest shares is $280
Step-by-step explanation:
Total amount to be shared = $560
Ratios of share are 2:3:9 => Total of 14 equal portions
To get one portion, $560 / 14 = $40
First share is 2, therefore $40 x 2 = $80 (smallest share)
Second share is 3, therefore $40 x 3 = $120
Third share is 9, therefore $40 x 9 = $360 (largest share)
<u>TOTAL = $560</u>
The difference between the largest and the smallest = $360 - $80
= $280
