Will mark brainliest for this: A rectangle is mesured 3 cm by 6 cm. Three of theses rectangles are put together to make a larger rectangle. Work out the perimeter of the larger rectangle it is: 3 cm x 2 and 6 cm x 2 plus the height of the the two rectangles times 2 Hope this makes sense if you have any questions feel free to ask me

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

total length = 6 + 6 + 6 = 18 cm

total breadth = 3 + 3 + 3 = 9 cm

perimeter = 2 ( l + b )

= 2 ( 18 + 9 )

= 2 × 27

For today’s lunch, a school cafeteria’s budget allows it to purchase at most 60 cans of beans and 45 cans of corn. 1 can of beans feeds 5 students, and 1 can of corn feeds 6 students. Each student will have beans or corn, but not both, and there will be a maximum of 420 students at lunch. If a can of beans cost $2.00 and a can of corn cost $3.00, what is the maximum amount of money required to feed all of the students either beans or corn?A: $180

B: $195

C: $210

D: $225

Answers

Answer:

Option B.

Step-by-step explanation:

Let x be the number of cans of beans and y be the number of cans of corn.

Cafeteria’s budget allows it to purchase at most 60 cans of beans and 45 cans of corn.

$x\leq 60$

$y\leq 45$

1 can of beans feeds 5 students, and 1 can of corn feeds 6 students. Each student will have beans or corn, but not both, and there will be a maximum of 420 students at lunch.

$5x+6y\leq 420$

Can of beans cost $2.00 and a can of corn cost $3.00.

Objective function, Z=2x+3y

The required linear programming problem is

Objective function, Z=2x+3y

Subject to the constraints

$x\leq 60$

$y\leq 45$

$5x+6y\leq 420$

$x\geq 0, y\geq 0$ (Only 1st quadrant)

Draw the graph of these constraints as shown below.

The verities of common shaded region are (0,45), (30,45), (60,20), (60,0), (0,0).

Points Z=2x+3y

(0,0) 0

(0,45) 135

(30,45) 195

(60,20) 180

(60,0) 120

The maximum amount of money required to feed all of the students either beans or corn is $195.

Number of cans of beans = 30

Number of cans of corn = 45

Therefore, the correct option is B.

I would go with B, one hundred ninety five dollars. Hope that this would help you..

Adele has 3 64-ounce cartons of orange juice and 3 48-ounce cans of apple juice. How much juice does she have altogether?

Answers

three 64 oz cartons = 3 * 64 = 192 oz
three 48 oz cans = 3 * 48 = 144 oz
192 + 144 = 336 oz <== total juice

Answer: 336 oz

Step-by-step explanation: three 64 oz cartons = 3 * 64 = 192 oz

three 48 oz cans = 3 * 48 = 144 oz

192 + 144 = 336 oz <== total juice

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31

Answers

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

$y=2(4)^2-16(4)+31\ny=2(16)-64+31\ny=32-64+31\ny=1$

The vertex is (4,1).
