Step-by-step explanation:
Using pythagoras theorem
Sqrt(9^2-5^2)=7.483
Answer:
B is the correct answer
Step-by-step explanation:
A. is wrong because 3/8 would shrink the circle, not expand it.
B. is correct because 8/3 means the circle will expand, not shrink.
C. is wrong because those coordinates only reposition and move the circle, not dilate.
D. is wrong because those coordinates only reposition and move the circle, not dilate.
Answer:
length = 8
width = 4
Step-by-step explanation:
Area = length x breadth
Let x represent the width
length = x + 4
32 = x × (x + 4)
32 = x² + 4x
x² + 4x - 32 = 0
solving using quadratic equation =
(x² - 4x) -32 + 8x
x = 4 or -8
since width cannot be a negative number, we would use 4
<span>Distance is equal to rate times time, and time is the unknown in this instance. To find time, divide distance by rate. In this case, Joe wants to use a rate five miles per hour less than his planned speed of 75 miles per hour, which is 70. Dividing 310 miles by 70 miles per hour yields an expected travel time of 4.4 hours.</span>
