Answer:[tex]\frac{11}{-2}[/tex]

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

[tex]\frac{y2-y1}{x2-x1} =[/tex] m

so when using that formula with the cords, you get

[tex]\frac{4-(-7)}{-6-(-4)}[/tex]

and then subtract everything and you'll get

Answer:

1) 150 kg

2) 97.5 kg

3) 5%

Step-by-step explanation:

Ratios of each metal to total mass of metal can be computed by dividing its corresponding value by the sum of all the values in the ratio

The ratio of zinc to metal = 6/(13 + 6 + 1) = 6/20 = 3/10

Let the total mass of the metal be X

Then mass of zinc = (3/5)X = 90 kg (given)

1) Multiplying both sides by 5/3 gives X = 5/3 x 90 = 150 kg which is the total mass of metal

2) Ratio of copper to metal mass = 13/20
Mass of copper = 13/20 x 150 = 97.5 kg

3) Mass of lead as a ratio of metal = 1/20 = 0.05

As percentage, multiply by 100 to get 0.05 x 100 = 5%

Answer:

A. 32.8%

Step-by-step explanation:

Blake's incomes are $3,200 each month.

His debts are:

$600 per month for housing

$300 per  month for a car loan

$150 per month in  other debt payments

Total payments: $600+$300+$150=$1,050

The debt-to-income ratio is calculated by:

[tex]\displaystyle r=\frac{1,050}{3,200}\cdot 100\%[/tex]

r = 32.8%

Answer:

C. 574.53

Step-by-step explanation:

Option C) is correct work done = 574.53.

Force = 15 pounds
distance = 50 feet
Ф = 40°

work done is product of force and cosine of displacement.

work done = force x displacement x cosФ
= 15 x 50 x cos40
= 15 x 50 x 0.76
= 574.53

Thus the required work done is 574.53 to pull the wagon.

Answer: 6 of the flowers are pink

Step-by-step explanation:

If 3/5 of the flowers are yellow you would convert the 3/5 into a 9 because 1/5 of 15 is 3 so you would multiply 3 by 3 to get nine. By doing this you will find out the 2/5 or the remaining flowers are pink which makes 6 pink flowers.

The distance between (-8,0) and (-5,3) in the coordinate plane is 9 units.

Given that the coordinates of points in the coordinate plane are (-8,0) and (-5,3).

We are required to find the distance between the given points.

Distance is basically a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to physical length or an estimation based on other criteria.

Distance between (-8,0) and (-5,3)=[tex]\sqrt{(-5+8)^{2} +(3-0)^{2} }[/tex]

=[tex]\sqrt{3^{2} +3^{2} }[/tex]

=[tex]\sqrt{9+9}[/tex]

=[tex]\sqrt{81}[/tex]

=9 units

Hence the distance between (-8,0) and (-5,3) in the coordinate plane is 9 units.

Answer:

I think it is 90 and 100

Step-by-step explanation:

I used this equation: x is the speed of the slower train

910 = (5x + 10) + 5x

Answer:

The answer is 86 and 96 mph

Step-by-step explanation:

Givens

Train A

Distance traveled = d

time taken = 5 hours

rate traveled = r

Train B

Distance traveled = 910 - d

time taken = 5 hours

rate = r + 10

Formula

basically d = r * t

Solution

Train A: d/r = 5 or d = 5*r

Train B = (910 - d)/(r + 10) = 5    or

Substitute d = 5*r   into Train B

(910 - 5*r)/(r + 10) = 5        Multiply both sides by r + 10

(910 - 5r) = 5 * (r + 10)       Remove the brackets on both sides

910 - 5r = 5r + 50             Add 5r to both sides

910 = 5r + 5r + 50

910 = 10r + 50                  Subtract 50 from both sides

910 - 50 = 10r                  Combine the left

860 = 10r

10r = 860                         Divide by 10

r = 860/10

r = 86

r + 10 = 96

Check

Train A distance: 5*r = 5 * 86 = 430

Train B distance: 5*r = 5 * 96 = 480

Total =                                         910

Answer:

The solution to the system of equations be:

[tex]y=4,\:x=0[/tex]

As the consistent system of equations has only one solution, it is independent.

Step-by-step explanation:

Given the system of equations

[tex]3y + 2x= 12[/tex]

[tex]36 - 9y = -6x[/tex]

solving the system of equations

[tex]\begin{bmatrix}3y+2x=12\\ 36-9y=-6x\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}3y+2x=12\\ -9y+6x=-36\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}3y+2x=12\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:9y+6x=36[/tex]

[tex]\begin{bmatrix}9y+6x=36\\ -9y+6x=-36\end{bmatrix}[/tex]

so

[tex]-9y+6x=-36[/tex]

[tex]+[/tex]

[tex]\underline{9y+6x=36}[/tex]

[tex]12x=0[/tex]

[tex]\begin{bmatrix}9y+6x=36\\ 12x=0\end{bmatrix}[/tex]

solve 12x=0 for x

[tex]12x=0[/tex]

Divide both sides by 12

[tex]\frac{12x}{12}=\frac{0}{12}[/tex]

[tex]x=0[/tex]

[tex]\mathrm{For\:}9y+6x=36\mathrm{\:plug\:in\:}x=0[/tex]

[tex]9y+6\cdot \:0=36[/tex]

[tex]9y=36[/tex]

Divide both sides by 9

[tex]\frac{9y}{9}=\frac{36}{9}[/tex]

[tex]y=4[/tex]

Thus, the solution to the system of equations be:

[tex]y=4,\:x=0[/tex]

As the consistent system of equations has only one solution, it is independent.

Answer:

5 weeks

Step-by-step explanation:

To find the answer to this question we have to write an equation for both situation and put them equal to each other.

Let's write an equation for Joe:

12x + 100

Now, for Jessica

6x + 130

Next, put them equal to each other:

12x + 100 = 6x + 130

Solve:

12x + 100 = 6x + 130

6x + 100 = 130

6x = 30

x = 5

Therefore, it will take 5 weeks for Joe and Jessica to have the same amount of cards.

Check:

12(5) + 100 = 6(5) + 130

60 + 100 = 30 + 130

160 = 160

Answer:

A.

Step-by-step explanation:

I believe the answer is A. (Line JK and line LM will be parallel) because lines EF and GH are parallel. Therefore if the are just reflected, the new set of lines will also be parallel.

EF: (-9,1) (-4,9)

[tex]\frac{1-9}{-9+4}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6

GH: (-5,-2) (0,6)

[tex]\frac{-2 - 6}{-5-0}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6

Same slope and different y-intercept means the lines a parallel
