Total of 15 books
autobio is 2 so 2/15
fantasy is 3 so 3/15
2/15 * 3/15 = ___________ You can finish I hope !
Area of circle MINUS area of square = shaded area
pi r^2 - s * s = shaded area
pi (4)^2 - (sqrt2) * (4 sqrt2) = shaded area You should be able to get it from here ......
As n increases the value of 60 - 8n decreases
60 - 8(1) = 52
60 - 8(2) = 44
60 - 8(3) = 36
etc
YMIR AND BIN NOT NEXT TO EACH OTHER
y x b x
b x y x
x y x b
x b x y
y x x b
b x x y six ways
for each of them the other two spots can be filled in two ways with charles and daria 6 x 2 = 12 ways (as ds1119 found)
y = -16t^2 +80t
80 = -16 t^2 + 80t
-16t^2 +80t - 80 = 0 quadratic formula shows t = ~1.4 SECONDS
FIrst one .... no values of x have two values of y YES
Second one 6.6 and 6,8 means the value of x = 6 has two values for y NO
Third one 7,-4 7, -6 NO
Fouth one -5,1 -5,3 no
x2 = 4
take square root of both sides
x = ± 2
Area of a rectangle = length x width = 2 x 1 = 2 units2
d = dimes
q = quarters
q = 2d
25 q + 10d = 420
25 (2d) + 10d = 420
60d = 420
d = 7 the q = 2d = 14
Take the average of the two bases (12+18)/2 = 15
Area = 15 * 11 = 165 mm2
