Answer:

292.5

Step-by-step explanation:

calculations

45 percent of 650 Is 292.5

Step-by-step explanation:

I think what is meant in the triangle ABC we have the three angles.

the sum of all angles in a triangle is airways 180 degrees.

so,

180 = A + B + C

180 = 42 + B + C

now, we know also that

B = 5×C

so, we can use that above

180 = 42 + 5×C + C

138 = 6×C

C = 138/6 = 23 degrees

B = 5×C = 5×23 = 115 degrees

Answer: The answer should be D

Answer:

I'll assume "S2x+3y=-12" is actually 2x+3y=-12 and that the question is to solve for x and y.

x = -(9/5)

y = -(14/5)

Step-by-step explanation:

2x+3y=-12

4x-4y=4

---

2x+3y=-12

8x+12y=-48  [Multiply the 1st equation by 4]

12x-12y=12   [Multiply the second equation by 3]

20x = -36     [Now we can add the two equations to remoce the y term]

x = -(36/20)  

x = -(9/5)       [The value for x]

====

2x+3y=-12        [Take either equation and s=use x=-(9/5) to find y]

2(-9/5)+3y=-12  

-(18/5) + 3y = -12

+ 3y = -12 + (18/5)

y = -4 + (6/5)

y = -(20/5)+(6/5)

y = -(14/5)          [This is the value of y that will work for both equations]

These equations both have the point (-9/5, -14/5) in common:  they intersect here.

This problem can also be solved by graphing each equation and finding the point they inersect on the graph (attached).

Answer:

9 puppies

Step-by-step explanation:

12*0.75=9

75% remains

Answer:

9

Step-by-step explanation:

Number of puppies before adoption = 12

[tex]Number \ of \ puppies \ adopted = \dfrac{25}{100}*12 = \dfrac{1}{4}*12 = 3[/tex]

Number of puppies that remain = 12 - 3 = 9

Answer:

$49,592.50

Step-by-step explanation:

First, to find the total fee of application you times 910 by $1.75 which will give you

910 × 1.75 = 1592.5

Then you add 48,000 with 1,592.5

which will give you an answer of

48,000 + 1,592.5 = $49,592.50

Answer:

local governments have the most power

Step-by-step explanation:

I hope this is right, but federalism gives more power to the state, so local governments could potentially have more power.

Answer:

i believe it is option one: power and authority are concentrated in the central government and can take away people’s rights

Step-by-step explanation: well i mean its true the governments are corrupted and are slowly taking away our rights

Explanation:

A cube has 6 identical faces, all of which are squares.

Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.

The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm

Answer:

A=433.5cm²

Step-by-step explanation:

A=6a2=6·8.52=433.5cm²

Answer:

y=-1/2x+2

Step-by-step explanation:

2 = 0 +b

2=b

y=-1/2x+2

Answer:

y = -1/2x + 2

Step-by-step explanation:

Follow the y = mx + b. B stands for the y-intercept, which is 2 in this case. M stands for the slope, which is the constant -1/2. Pls brainliest i want to level up ty!!!!!

Answer:

merry Christmas to you advance

Answer:

(x,-y): (2,-2)

Step-by-step explanation:

M=(x+x)/2,(y+y)/2

Given (1,4)=

[tex] \frac{3x - 4}{2} [/tex]

This implies:

[tex]1 = \frac{3x - 4}{2} [/tex]

[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]

In a similar way,

[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]

The question demanded (x,-y)

Hence(2,-2) is the answer

Answer:

X = -1 & and for some additional information Y = -5

Step-by-step explanation:

6 x (-1) = (-6)

5 x (-5) = (-25)

(-6) - (-25) = (-31)

_____________

5 x (-1) = (-5)

3 x (-5) = (-15)

(-5) + (-15) = 10

Answer:

  x = -1

Step-by-step explanation:

Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...

  x = -1

__

If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)

  3(6x -5y) +5(5x +3y) = 3(-31) +5(10)

  18x -15y +25x +15y = -93 +50 . . . . . . eliminate parentheses

  43x = -43 . . . . . . . . . . . . . . . . . simplify

  x = -1 . . . . . . . . . . . . . . . . . divide by 43

Answer:

If a line goes through both points, the slope of that line would be [tex]0[/tex].

Step-by-step explanation:

The slope of a line is equal to the ratio between the vertical change of this line "rise" and the corresponding horizontal change "run":

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}}\end{aligned}[/tex].

If a non-vertical line goes through two distinct points [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex], the vertical change (rise) would be [tex](y_{1} - y_{0})[/tex]. The corresponding horizontal change would be [tex](x_{1} - x_{0})[/tex]. Thus, the slope of that line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].

In this question, [tex]x_{0} = 4[/tex] and [tex]y_{0} = 5[/tex] for the first point, whereas [tex]x_{1} = 3[/tex] and [tex]y_{1} = 5[/tex] for the second point.

The rise (vertical change) of this line from the first point to the second would be [tex](y_{1} - y_{0}) = 5 - 5 = 0[/tex]. The corresponding run (horizontal change) would be [tex](x_{1} - x_{0}) = 3 - 4 = -1[/tex].

Thus, the slope of this line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{5 - 5}{3 - 4} \\&= \frac{0}{-1} \\ &= 0\end{aligned}[/tex].

In other words, the slope of this line is [tex]0[/tex]. Geometrically, a slope with a slope of [tex]0\![/tex] would be horizontal. The vertical coordinate of all points on such line would be the same ([tex]5[/tex] for points on the line in this question.)
