Help.. Suppose Q is the midpoint of PR

8090 [49]

Answer:

$3x+41$ or 38

Step-by-step explanation:

If Q is the midpoint of Line PR, then lines PQ and QR add up to equal Line PR. We then get

$PQ=6x+25\\QR=16-3x\\PQ+QR=PR\\6x+25+16-3x=PR\\3x+41=PR\\$

If you want to know the exact number that PR is, we can do additional steps where PQ = QR.

$PQ=6x+25\\QR=16-3x\\PQ=QR\\6x+25=16-3x\\9x+25=16\\9x=-9\\x=-1\\\\3x+41=PR\\3(-1)+41=PR\\-3+41=PR\\38=PR\\PR=38$

Which equation can be used to solve for x in the triangle below?

belka [17]

Using the cosine rule, the equation to use to solve for x is: x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41)) ≈ 3.1 cm.

<h3>How to Use the Cosines Rule to Solve a Triangle?</h3>

The cosine rule is given as, c = √(a² + b² − 2ab × cos(C))

Given the following:

c = x = ?
a = 4.0 cm
b = 4.7 cm
C = 41°

Plug in the values:

x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41))

x ≈ 3.1 cm

Bob used identical cubes to build a rectangular tower that is 25 cubes tall, 5 cubes wide, and 6 cubes long. Beatrice used the s

Mazyrski [523]

Answer:

ok so first we have to find out how meaning cubes are in each tower so

bob 25*5*6=750

beatrice 12*3*5=180

ok so we want to see how many extra layers bob can add on with beatrices blockes so from looking at bobs tower we can see that 5*6 each layer is 30 so

180/30=6

so bobs will be 31 blocks tall

Hope This Helps!!!

The "feasible region" has vertices (4,5), (4,6), (7,4), and (3,6). If the "objective function" that you are trying to minimize i

Tanzania [10]

Answer:

The minimum value is 24

Step-by-step explanation:

we know that

The "feasible region" has vertices $(4,5), (4,6), (7,4),(3,6)$

The objective function is $C=4x+2y$

To determine the minimum value of the objective function, substitute the value of x and the value of y of each vertex in the objective function and then compare the values

1) For (4,5)

x=4,y=5

$C=4(4)+2(5)=26$

2) For (4,6)

x=4,y=6

$C=4(4)+2(6)=28$

3) For (7,4)

x=7,y=4

$C=4(7)+2(4)=36$

4) For (3,6)

x=3,y=6

$C=4(3)+2(6)=24$

therefore

The minimum value is 24
