Answer:
Width = 12 feet
Step-by-step explanation:
Given that,
Area of a rectangle is 168 square feet.
The ratio of the width to the length is 6:7.
Let the length is 7x and width is 6x.
According to question,
Area = 168 sq feet
l×b=168 sq feet
7x × 6x = 168
42x² = 168
x² = 4
x = 2
Length = 7x = 7(2) = 14 feet
Breadth = 6x = 6(2) = 12 feet
So, the width of the rectangle us 12 feet.
Answer:
m = -10
Step-by-step explanation:
2.1m - 1.3m = -8
Solve the left side
We have
0.8m = -8
Divide both sides by 0.8 to isolate m
0.8m/0.8 = -8/0.8
m = -10
Answer:
a = 3x + 6y
Step-by-step explanation:
You start by flipping the equation.
After that there is not enough information to solve for a.
The probability that Nathan is not allergic to penicillin, like his father and paternal grandfather, is <u>24.5%</u>.
<h3>What is probability?</h3>
Probability estimates the likelihood of an event occurring.
Probability is expressed as a percentage, decimal, or fraction, and must be less than or equal to one.
<h3>Data and Calculations:</h3>
Nathan's chances of having the same allergy = 75%
Nathan's probability of not having the same allergy = 25% (1 - 75%)
Accuracy of test performed by the doctor = 98%
The probability that Nathan is not allergic to the drug after the test = 24.5% (25% x 98%).
Thus, the probability that Nathan is not allergic to penicillin is <u>24.5%</u>.
