Answer:
d
Step-by-step explanation:
Circles with the same centre are concentric circles
A = l × w. Substitute 72 into A and fill in the rest of the equation.
w = l - 1. Plug l - 1 into w
72 = l × (l - 1). Multiply l by (l - 1)
72 = l^2 - l. Subtract 72 from each side.
0 = l^2 - l - 72. Factor.
0 = (l + 8) (l - 9). Set each term equal to zero.
(l + 8) = 0. Subtract 8 from each side.
l = -8. Length cant be a negative number so let's try the other term.
(l - 9) = 0. Add 9 to each side.
l = 9. The length is 9.
Earlier we stated that the width is one less than the length, therefore, the width is 9 - 1 = 8.
The width is 8 units.
Answer:
f(3/2)= 5√5
Step-by-step explanation:
f(3/2)= 5^(3/2)
f(3/2)= (5^3)^1/2 is the same things
f(3/2)= (125)^1/2 fraction exponent are the same are roots ^(1/2) is √
f(3/2)= √125
f(3/2)= √25 times √5 break up 125 to be 25 x 5
f(3/2)= 5√5 because √25 = 5 and √5 stays as √5
Answer:
2.25 or 2 1/4 pounds
Step-by-step explanation:
if you add them all up (I converted them to decimals when adding) you get 13.5 or 13 1/2 if your using fractions, then you divide that by 6 because thats how many jars there are and you get 2.25 or 2 1/4
