Answer:
The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m
Step-by-step explanation:
The perimeter of the existing field is
2(l + b)
= 2(90 + 60) = 2(150) = 300 yards
So we want another field having the same perimeter but a larger area
The area we have here is 90 * 60 = 5,400 square yards
If we had 80 by 70
Perimeter will still be 2(70 + 80) = 150
But the area will be 80 * 70 = 5,600 square yards
Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
0.0713 = 7.13% probability that the result is positive.
So, you should add the heighth twice and add the width twice too, then add those two together to get your answer.
Answer:
-53
Step-by-step explanation:
If x=3 and y=-4
Plug the numbers into the equation
3 - (-4) - 3 + (-57)
Now solve the equation right to left
3 - (-4) = 7
7 - 3 = 4
4 - 57 = -53
So the answer is -53
