Joe uses 16 pounds of fertilizer in his three gardens. He uses 3/8 of the fertilizer in his first garden and 1/4 of the fertiliz

enot [183]

Answer: The fraction of the fertilizer is left = $\dfrac38.$

Step-by-step explanation:

Given: Fraction of fertilizer used in first garden = $\dfrac38$

Fraction of fertilizer used in second garden = $\dfrac14$

Fraction of fertilizer used in third garden = 1- (Fraction of fertilizer used in first garden)-(Fraction of fertilizer used in second garden)

= $1-\dfrac38-\dfrac14$

$=\dfrac{8-3-2}{8}\\\\=\dfrac{3}{8}$

Hence, the fraction of the fertilizer is left = $\dfrac38.$

(x+4),(x+12),(x-1) and (x+5) are in proportion .find the value of x

BaLLatris [955]

Answer:

x = 16

Step-by-step explanation:

(x +4) : (x +12) :: (x-1)(x +5)

As they are in proportion,

Product of means = Product of extremes

(x + 4)* (x +5) = (x + 12)(x - 1) {Use FOIL method}

x*x +x*5 +4*x + 4*5 = x *x + x*(-1) +12*x + 12*(-1)

x² + 5x + 4x + 20 = x² - x +12x - 12 {Now combine like terms}

x² + 9x + 20 = x² + 11x -12

x² + 9x +20 - x² - 11x = -12

x² - x² + 9x - 11x = -12 - 20

0 - 2x = - 32

-2x = -32 {Divide both sides by -2}

x = -32/-2

x = 16

The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,0

kobusy [5.1K]

Answer:

4.43

Step-by-step explanation:

Given :The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,034 games played

To Find : What is the expected number of wins for the that upcoming month?

Solution :

The probability that the San Jose Sharks will win is 0.3694

Let X = number of games won

Total no. of games = 12

We are supposed to find the expected number of wins for the that upcoming month

So, expected number of wins = E(X)=XP(X)= $12 \times 0.3694 =4.43$

Hence the expected number of wins for the that upcoming month is 4.43

Which is greater 0.5 liters or 400 millimeters

Lana71 [14]

100 Millimeters = 0.1 meters P.S I think you either meant liters or meters

so 0.5 meters = 500 millimeters

0.5 meters would be greater

If f(x) = 3x4 + 2x3 - x + 15, what would be the list of possible rational roots?

Lesechka [4]

Answer: A. ± $\frac{1}{3} ,\frac{5}{3} ,1,3,5,15$

Step-by-step explanation:

± $\frac{1, 3, 5, 15}{1, 3}$

= ± $1, 3, 5, 15, 1/3, 5/3, 5$

Rearranging, we get:

= ± $\frac{1}{3} ,\frac{5}{3} ,1,3,5,15$
