Answer:

2:1

Step-by-step explanation:

First we convert 3 pounds into ounces which is 3x16 because 1 pound=16 ounces. So 48 ounces=3 pounds. So know we have the ratio 48:24 which we can simplify to 2:1

Hope this helps :)

The equation 6x2 - 132 +5 -0 has solutions of the form

MArishka [77]

Answer:

(A)

$N = -b = -(-13) = 13\\\\$

$D =b^2 -4ac = (-13)^2 - 4(6)(5) = 169- 120 = 49$

$M = 2a = 2(6) = 12$

(B)

$x = (\frac{5}{3} , \: \frac{1}{2})$

Step-by-step explanation:

The given equation is

$6x^2 - 13x + 5 = 0$

The solution is of the form as given by

$x=\frac{N\pm\sqrt{D}}{M}$

(A) Use the quadratic formula to solve this equation and find the appropriate integer values of N, M and D. Do not worry about simplifying the VD yet in this part of the problem.

The quadratic formula is given by

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

The equations of N, M and D are

$N = -b$

$D =b^2 -4ac$

$M = 2a$

The values of a, b and c are

$a = 6 \\\\b = -13 \\\\c = 5$

So,

$N = -b = -(-13) = 13\\\\$

$D =b^2 -4ac = (-13)^2 - 4(6)(5) = 169- 120 = 49$

$M = 2a = 2(6) = 12$

(B) Now simplify the radical and the resulting solutions. Enter your answers as a list of integers or reduced fractions, separated with commas. Example: -5/2-3/4

N = 13

D = 49

M = 12

$x=\frac{13\pm\sqrt{49}}{12}$

$x=\frac{13\pm7}{12}$

$x=\frac{13+7}{12}$ and $x=\frac{13-7}{12}$

$x=\frac{20}{12}$ and $x=\frac{6}{12}$

$x=\frac{5}{3}$ and $x=\frac{1}{2}$

$x = (\frac{5}{3} , \: \frac{1}{2})$

statuscvo [17]

Answer:

1.25 hours

Step-by-step explanation:

Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?

The number of hours he spent riding and walking to his friends house is calculated as:

45 minutes + 30 minutes

= 75 minutes

Converting this to hours

60 minutes = 1 hour

75 minutes = x

Cross Multiply

60 × x = 75 × 1

x = 75/60

x = 1.25 hours
