Answer:
Length of each piece = 16cm.
Step-by-step explanation:
Since the chart paper is 48cm x 32cm in size, finding the total area of the paper would be A = l x w, where l=length of the paper and w=width.
A = 48 x 32 = 1536cm²
Since Stitu was able to get 6 equal pieces, then we can take the total area and divede by 6:
Since 256cm² represents the area of each square, we can take the square root of this number to find the length of just one square since the formula for the area of a square is A=s², where s=the length of one side:
s² = 256 so √s² = √256 or s = 16cm
Answer:
The policy pay $47200 .
Step-by-step explanation:
As given
An insurance policy pays 80% of the first $20,000 of a patient's medical expenses, and 60% of the remainder.
80% is written in the decimal form.
= 0.80
Medical expenses pay by the insurance policy on first $20000 = 0.80 × 20000
= $16000
As given
Insurance policy pays 60% of the remainder.
The patient's total medical bill is $72,000.
Patient medical bill over $20000 = $72000 - $20000
=$52000
60% is written in the decimal form.
= 0.60
Medical expenses pay by the insurance policy on the remainder = 0.60 × $52000
= $31200
Total Medical expenses pay by the insurance policy = Medical expenses pay by the insurance policy on first $20000 + Medical expenses pay by the insurance policy on the remainder .
Total Medical expenses pay by the insurance policy = $16000 + $31200
= $47200
Therefore the policy pay $47200 .
I hope my steps were clear. this involves the difference of squares and factoring
Subtract 15 from both sides.
5x=-15
Divide by 5
x=-5
