Answer:
40/49
Step-by-step explanation:
probability that a point chosen at random in the given figure will be inside the larger circle and outside the smaller circle = ( area larger circle - area of smaller circle / area of larger circle )
area of a circle = πr² where r = radius
area of smaller circle :
radius = 6
==> plug in 6 for r
A = π(6)²
==> evaluate exponent
A = 36π
Area of larger circle :
Radius = 14
==> plug in 14 for r
A = π(14)²
==> evaluate exponent
A = 196π
We have probability = area larger circle - area of smaller circle / area of larger circle
area of larger circle = 196π
area of smaller circle = 36π
probability = (196π - 36π)/196π
==> subtract 36 from 196
probability = 160π/196π
==> simplify fraction and cancel out π
probability = 40/49
Answer:
five and eight hundredths
Step-by-step explanation:
I was taught to reserve the word "and" to mark the decimal point when the number has a fraction. The integer part is "five." The fractional part is "eight hundredths." Together, the word form might be ...
five and eight hundredths.
__
If I were reading this to someone, including myself, I might say it as ...
"five point oh eight".
_____
<em>Comment on ambiguity</em>
The reason for being particular about marking the decimal point is so you don't get into trouble with something like ...
1000.13 . . . . . one-thousand and thirteen hundredths
which is different from ...
1013/100 . . . . one-thousand thirteen hundredths
Some folks will pronounce 1013 as "one-thousand and thirteen." Doing so will get you in trouble in the above situation, where you have 1013/100.
Answer:
42:49
Step-by-step explanation:
6x + 7x = 91
13x = 91
x = 7
6 x 7 = 42
7 x 7 = 49
then 42:49
Answer:
174 ft²
Step-by-step explanation:
The polygon cam be decomposed into two rectangles.
The area of the polygon = rectangle A + rectangle B
Area of rectangle A = L* W
L = 18 ft
W = 9 ft
Area of rectangle A = 18*9 = 162 ft²
Area of rectangle B = L* W
L = 20 - 18 = 2 ft
W = 6 ft
Area of rectangle A = 2*6 = 12 ft²
✔️Area of the polygon = 162 + 12 = 174 ft²
$81 x 3 = triple the savings = $243
$243 - $26 = what Jennifer has saved which equals = $217
I think that’s how you do it, anyways hope this helped!
