Answer:
Step-by-step explanation:
The perimeters are equal, so
2a+2b = 4a+b
b = 2a
area of rectangle is between 80 and 100
80 < ab < 100
substitution
80 < a(2a) < 100
40 < a² < 50
√40 < a < √50
6.4 < a < 7.1
Since a is an integer, a = 7.
b = 2a = 14.
Answer: 17.5%
Step-by-step explanation:
Percentage of chips given to Jackie = 20%
Percentage of chips given to Ronald = 20%
Percentage of chips given to Mark = 1/4 × 100 = 25%
From the above calculation, we can see that Ms Johnson has given out ((20% + 20% + 25%) = 65% worth of chips out. The percentage she'll have left will be:
= 100 - 65
= 35%
Since Susan takes half of what's left, the percent that Ms. Johnson has left to eat will be:
= 1/2 × 35%
= 17.5%
She has 17.5% left to eat.
Answer:
Step-by-step explanation:
<em>Let P(W) represents the probability that Paul wins</em>
<em>Let P(W') represents the probability that Paul does not win</em>
Given
Required
In probability, the sum of opposite probability equals 1;
This implies that
Substitute in the above equation
becomes
Subtract from both sides
Solve fraction (start by taking the LCM)
Hence, the probability that Paul doesn't win is

Answer:
5/12 miles
Step-by-step explanation:
Distance of the field from where Maria lives = ⅝ miles
She walked ⅔ of ⅝ miles.
Therefore, she has walked:
= ⅔ * ⅝
= ⅓ * 5/4
= 5/12 miles
