Answer:

First backpacker should receive $4 and the second one $2

Step-by-step explanation:

notice that the total amount of rice for the three is 600 g.

Then, the first one that gave 400 g contributed 400 out of 600, that is 400/600 = 2/3

The second one contributed 200 out of 600, that is 200/600 = 1/3

then the first one should receive 2/3 of the $6 = (2/3) x 6 = $4

and the second one should receive 1/3 of the %6 = (1/3) x 6 = $2

Help me with question 3.<br><br> (It will be 33 points)
adoni [48]

Answer:

PartA

P = 4a

Part B

60 = P fence + 2a

60 = 6a

Part C

40

Step-by-step explanation:

We are building a fence so we are finding perimeter.

Adding the 3 sides

P = a+b+a

P = 2a+b

It is twice as long as it is wide

b= 2a

Replace in the equation for perimeter

P = 2a+(2a)

P = 4a

Part B

We know the perimeter is 60 for the entire backyard

The perimeter of the backyard is  the fence plus the longer side

60 = P fence + b

Replacing b

60 = P fence + 2a

We know the equation for the perimeter of the fence is

60 = 4a + 2a

Combing like terms

60 = 6a

Part C

Solve for a and b

60 = 6a

Divide each side by 6

60/6 = 6a/6

10 =a

P fence = 4a

P = 4(10) = 40

Which graph shows the quadratic function y = 3x2 − 12x + 10? (5 points)
eduard

ANSWER

The graph in option D.

EXPLANATION

The given function is:

y = 3 {x}^{2}  - 12x + 10

We complete the square to obtain:

y = 3( {x}^{2}  - 4x) + 10

y = 3( {x}^{2}  - 4x +  {( - 2)}^{2} ) + 10  -  3 {( - 2)}^{2}

y = 3{( x- 2)}^{2}+ 10  - 12

y = 3{( x- 2)}^{2}  - 2

The graph of this function opens upwards and has its vertex at (2,-2).

The y-intercept is 10.

From the options the graph that satisfies all these properties is D.
