pound. This month, Yolanda made 130 pounds of the blend, for a total cost of $586.30. How many pounds of type B coffee did she use?

Answer:

x=10,y =4

Step-by-step explanation:

x + y = 14

X-y=6​

Add the two equations together to eliminate y

x + y = 14

X-y=6​

-----------------------

2x +0y = 20

Divide by 2

2x/2 =20/2

x = 10

Then find y

x+y = 14

10+y =14

Subtract 10 from each side

10+y-10=14-10

y =4

Answer:

x = 10, y = 4

Step-by-step explanation:

One way of doing this is by doing the substitution method

To do this you first need to put x on one side (x = y + 6)

Now where there is an x in the first equation you put that instead

(y + 6) + y = 14

After this, you solve for y (y = 4)

Lastly, you put the 4 where there is a y and then solve for x

x - 4 = 6

x = 10

Answer:

D

Step-by-step explanation:

2/5 is 40%, so we need to find 40% of 25. .40 x 25 = 10. We see that 31 - 40 has 8 values and 41 to 50 has to, and 8 + 2 = 10, so our answer is D.

Answer:

3

Step-by-step explanation:

(x - 2)^2 + (y - 4)^2 = 9

The equation of a circle is written as

(x-h)^2+ (y-k)^2 = r^2

where ( h,k) is the center and r is the radius

(x - 2)^2 + (y - 4)^2 = 3^2

The center is ( 2,4) and the radius is 3

Answer:

r = 3

Step-by-step explanation:

The stock equation for a circle of center (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.  Comparing this with the given (x - 2)^2 + (y - 4)^2 = 9, we see that r^2 must be 9 and therefore r = 3.

Answer:

y = 2x + 125

Step-by-step explanation:

y = mx + c

c in this problem is $125.

It is the amount of money she has already saved, that is not going to change, so this is the y intercept.

She saves $2 every day, with the number of days being x.

So she saves $2 × x = 2x

2x is the gradient.

On your graph, your straight lien should run through 125 on the y-axis.

The line should have a gradient, or slope, of 2x.

Make sure to plot carefully, looking at the scale of the graph.

The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Anna is saving to get a few keepsakes on a family excursion. She has previously saved $125, and she saves another $2 from her remittance consistently.

Let 'x' be the number of days and 'y' be the total cost. Then the equation is given as,

y = 2x + 125

The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.

Answer:

Step-by-step explanation:

Answer:

Length = 5 units, Area = 51 unit squared

Step-by-step explanation:

For the length of the midsection (I think this is what you're talking about):

Method 1.

Draw the graph and count the units across for the length.

Method 2.

The lowest y coordinates are the 0 from point A and the 0 from point B: this means that the line between point A and B is the bottom line of the trapezoid.

The highest y coordinates are the 6 from point C and the 6 from point D: this means that the line between point C and D is the top line of the trapezoid (parallel to line AB).

Since the length of the midsection is essentially the shorter line of the two parallel lines, it is the length between point C and point D.

(10, 6) - (5, 6) = 5, so the length of the midsection is 5 units.

For the area:

Step 1. Add the lengths of the pair of parallel lines.

5 units + 12 units = 17 units

Step 2. Divide the answer to step 1 by 2.

17 units ÷ 2 = 8.5 units

Step 3. Multiply the answer to step 2 by the height between the two parallel lines.

6.5 units x 6 units = 51 units squared

Step-by-step explanation:

For part A, we want two inequalities that have F and D as solutions, but none of the other points. The easiest way to do this is construct two lines that pass through the origin, and then figure out which way the inequalities need to face based on the points we want to include. Our lines will be:

The first line intersects F and the second line intersects D, so we need to figure out which way to point the inequalities so both include the point they do not intersect:

So our system is:

Part B: To verify, plug in the x and y values for D and F and verify that it creates true statements in the system.

Part C: You can plug in the different x, y values for the points. The points which create true statements identify farms where chickens can be raised, while those which create false statements cannot raise chickens.

Answer:

[tex]\boxed{92 \: \mathrm{mm}}[/tex]

Step-by-step explanation:

sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

sin (60) = [tex]\frac{80}{x}[/tex]

x = [tex]\frac{80}{\mathrm{sin} (60)}[/tex]

x = 92.37604307...

x ≈ 92

Using the base dimension and either given angle you can solve for x

Sin(angle) = opposite leg/ hypotenuse

Sin(60) = 80/x

X = 80/sin(60)

X = 80/ sqrt(3)/2

X = 160/3 x sqrt(3). (This is exact answer)

For a decimal answer: 160/3 = 53 1/3

Multiplied by sqrt(3) = 92.376 mm

Rounded to nearest mm = 92

Answer:

72 square units.

Step-by-step explanation: You have to multiply both sides by the scale factor. 5 times 1.2 is 6, and 10 times 1.2 is 12. Then, multiply 6 by 12 to get your area of 66 square units.

Answer:

40 teachers.

For every 2 staff, there are 15 students

The number of teachers who attended the excursion is [tex]\frac{2}{17}[/tex]  × 340 = 40 teachers

The number of students who attended the excursion is [tex]\frac{15}{17}[/tex] × 340 = 300

Answer:

[tex]CD=4 \text{ cm }[/tex]

Step-by-step explanation:

We have a similarity of triangles. Once the side BC and ED are parallel,

[tex]$\frac{BC}{AC} =\frac{ED}{AD} $[/tex]

[tex]$\frac{10}{AC} =\frac{5}{4} $[/tex]

Once [tex]AC=AD+CD \Rightarrow AC=4+CD[/tex]

[tex]$\frac{10}{4+CD} =\frac{5}{4} $[/tex]

[tex]5CD+20=40[/tex]

[tex]5CD=20[/tex]

[tex]CD=4 \text{ cm }[/tex]

Both of these are ways to express linear equations.

[tex]y - y_1 = m(x - x_1)[/tex] is the equation for a line with slope m which contains the point [tex](x_1,y_1)[/tex]. This is called point-slope form.

[tex]y = mx + b[/tex] is the equation for a line with slope m and y-intercept b. That is, it contains the point (0, b). This is called slope-intercept form.

Both of these are perfectly valid ways of writing lines, though sometimes one will be easier to use than the other.

Answer:

Hey there!

Both of these can be used to write the equation of the line. However, for the Y-Y1=M(X-X1) equation, we must know one point on the line (X1, Y1) and the slope of the line, while in the Y=MX+B equation, we need to know the slope and the x or y intercept.

For example, we can convert from Y-Y1=M(X-X1) to Y=MX+B

For example, say the point is (2, 3) and the slope is 1

Then, we have Y-3=1(x-2)

This simplifies to Y-3=1x-2

And to Y=X+1

So it is very possible to change from one form to another.

Answer:

The beam will bend by 50 mm with a mass of 100kg?

Step-by-step explanation:

The first step in solving the problem of direct variation is setting up the relation mathematically.

We can do this as follows:

The bending of the beam varies directly as its mass.

[tex]20 \alpha 40kg[/tex]

[tex]\alpha[/tex] here is the symbol representing direct variation. To remove this and replace it with an equality sign, we have to introduce a constant of proportionality, k

[tex]20 = k \times 40[/tex]

k = 20 /40 = 0.5

We can now use this to find the distance the beam will bend with a mass of 100kg?

This will be

[tex]Bending = 0.5 \times 100 =50mm[/tex]

There fore, the beam will bend by 50 mm with a mass of 100kg?

Answer:

4th choice

Step-by-step explanation:

First we would just solve the equation since that is the easiest way. So 15 would be our a1 or first term and each time the number is being added by  4 so we would get an = -15 + 4(n - 1) for our final answer or the 4th choice

Answer:

option 4

Step-by-step explanation:

-15, -11 , -7 ,......

First term = [tex]a_{1}[/tex] = -15

Common difference = d = 2nd term -  1st term

                                 = -11 - [-15]

                                 = -11 + 15 = 4

Plug in the values of [tex]a_{1}[/tex] & d in the formula

[tex]a_{n} = a_{1} + d (n-1)\\\\a_{n} = -15 + 4*(n-1)[/tex]
