S = 1 / g t ² π, solve for t

Finger [1]

$s = \frac{1}{g {t}^{2}\pi }$

multiply through by

$g {t}^{2} \pi$

$s \times g {t}^{2} \pi = \frac{1}{g {t}^{2} \pi} \times g {t}^{2} \pi$

$sg {t}^{2} \pi = 1$

dividing through by

sgπ

${t}^{2} = \frac{1}{sg\pi}$

$t = \sqrt{ \frac{1}{sg\pi} }$

Greta wants to make 5 pounds of a nut mix using peanuts and cashews. Her budget requires the mixture to cost her $6 per pound. P

Vinil7 [7]

Answer:

3 pounds of peanuts and 2 pounds of cashews

Step-by-step explanation:

Let x be the pounds of peanuts and y be the pounds of cashews

Greta wants to make 5 pounds of a nut mix using peanuts and cashews.

So, $x+y=5$ ----- A

Cost of 1 pound of peanuts = $4

Cost of x pounds of peanuts = 4x

Cost of 1 pound of cashews = $9

Cost of y pounds of cashews = 9y

Her budget requires the mixture to cost her $6 per pound

So, cost of mixture of x pounds of peanuts and y pounds of cashews is 6(x+y)

So, $4x+9y=6(x+y)$ --- B

Plot A and B

$x+y=5$ ---Blue

$4x+9x=6(x+y)$ ---Green

Refer the attached figure

Intersection point = (x,y)=(3,2)

Hence she should use 3 pounds of peanuts and 2 pounds of cashews

mart [117]

Answer: He bought 6 pounds of coffee.

money he used to buy = 70.00 - 23.62 = 46.38

7.73 dollar = 1 pound

1 dollar = 1/(7.73) = 100/773 pound

46.38 dollar = (100/773) * 46.38 = 6 pound
