0.79 / 16 oz = 0.049 ( price for 1 oz of brown rice)

3.49 / 32 = 0.109 ( price for 1 oz of white rice)

the price per oz of brown rice is cheaper then 1 oz of white rice so the brown rice is the better deal

cody's Bikes rents bikes for $18 plus $5 per hour. Mark paid $48 to rent a bike. For how many hours did he rent the bike.

kkurt [141]

He rented the bike for 6 hours. If Cody charges an 18 dollar fee up front you subtract that from the total 48 to get 30. Then once you get down to the what he payed for the time used you divide it by 5 because that’s the hourly fee and get 6 hours

What is the value of cose in the diagram below?

Nuetrik [128]

Answer:

$cos \theta = 0.6$

Step-by-step explanation:

Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6, opposite = 0.8

$cos \theta = \frac{adjacent}{hypotenuse} , \ where \ adjacent = 0.6 ,\ hypotenuse \ = r= 1$

$cos \theta = \frac{0.6}{1}\\\\cos \theta = 0.6\\\\\theta = cos^{-1} \ 0.6\\\\\theta = 53.13^\circ$

4. This is a

bixtya [17]

Answer:

Step-by-step explanation:

4). This is an exponential function.

5). Let the equation of this function is,

f(x) = a(b)ˣ

Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,

For (-1, 4),

4 = a(b)⁻¹

4 = $\frac{a}{b}$ --------(1)

For (0, 6),

6 = a(b)⁰

a = 6

From equation (1),

4 = $\frac{6}{b}$

b = $\frac{6}{4}$ = 1.5

Therefore, equation of the function will be,

f(x) = 6(1.5)ˣ

6). Now the value of f(-4) will be,

f(-4) = 6(1.5)⁻⁴

= 1.185

An NFL coach sometimes uses a defense that utilizes 3 defensive linemen, 4 linebackers, and 4 defensive backs. His roster (the p

Alexandra [31]

Answer:

68,600

Step-by-step explanation:

The order of the players is not important. For example, a defensive line of Shaq Lawson, Ed Oliver and Jerry Hughes is the same as a defensive line of Ed Oliver, Shaq Lawson and Jerry Hughes. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Defensive Lineman:

3 from a set of 8. So

$C_{8,3} = \frac{8!}{3!5!} = 56$

56 combinations of defensive lineman

Linebackers:

4 from a set of 7. So

$C_{7,4} = \frac{7!}{4!3!} = 35$

35 combinations of linebackers

Defensive backs:

4 from a set of 7. So

$C_{7,4} = \frac{7!}{4!3!} = 35$

35 combinations of defensive backs

How many different ways can the coach pick the 11 players to implement this particular defense?

56*35*35 = 68,600

68,600 different ways can the coach pick the 11 players to implement this particular defense
