Answer:

11 pounds of Guatemala Antigua coffee

9 pounds of Arabian Mocha coffee

Step-by-step explanation:

Guatemala Antigua coffee - $10.20 per pound

Arabian Mocha coffee - $13.00 per pound

First find the total profit from the 20 pounds of the new coffee blend.

20 × $11.46 = $229.20

Now set up an equation.

$10.20g + $13.00a = $229.20

Use guess and check to find the number of pounds of each type of coffee.

$10.20g + $13.00a = $229.20

$10.20(11) + $13.00(9) = $229.20

$112.20 + $117 = $229.20

$229.20 = $229.20

It checks out. So, they should mix 11 pounds of Guatemala Antigua coffee and 9 pounds of Arabian Mocha coffee.

Hope that helps.

Since we are translating this graph one unit to the right, replace x with (x-1)

Note: If you are translating a graph to the left by k units, replace x with (x+k), and if by the right, replace x with (x-k)

[tex]y=|\dfrac{1}{2}(x-1)-2|+3[/tex]

After simplifying, we now have the following equation:

[tex]=|\dfrac{1}{2}x-\dfrac{5}{2}|+3[/tex]

This is the new equation. Let me know if you need any clarifications, thanks!

Answer:

we are given

y=|2x|-1

we are given to translate this equation

Whenever we translate any function to right side by 'c' units

we can replace x as x-c

Here , we have to translate one unit right

so, we can replace x as x-1

and we get

y=| 2( x-1 ) | 1

Answer:

Option A.

Step-by-step explanation:

there were 45 stamps purchased for $18.75. Some stamps were 40 cents, and some stamps were 55 cents.

Let x and y be the number of stamps of 40 cents and 55 cents respectively.

Total number of stamps is 45. So

[tex]x+y=45[/tex]

Total cost of stamps is $18.75. So

[tex]0.40x+0.55y=18.75[/tex]

But Krista wrote the system of equations as

[tex]0.40x+y=45[/tex]

[tex]x+0.55y=18.75[/tex]

Krista put 0.40 in the first equation meant for the number of stamps.

Krista did not write 0.40 in the second equation meant for the value of stamps.

Therefore, the correct option is A.

Step-by-step explanation:

a ∆ b = a² + ab + b²

(3 ∆ 2)

a = 3 b = 2

(3 ∆ 2) = 3² +3(2) + 2²

= 9 + 5 + 4

Hope this helps you

=====================================================

Work Shown:

First we compute 3 △ 2

a △ b = a^2 + ab - b^2

3 △ 2 = 3^2 + 3*2 - 2^2 ... replace 'a' with 3, replace b with 2

3 △ 2 = 9 + 6 - 4

3 △ 2 = 15 - 4

3 △ 2 = 11

Replace the ( 3 △ 2 ) in the original expression with 11.

We now want to find 11 △ 13

a △ b = a^2 + ab - b^2

11 △ 13 = 11^2 + 11*13 - 13^2

11 △ 13 = 121 + 143 - 169

11 △ 13 = 264 - 169

11 △ 13 = 95

Step-by-step explanation:

15, Complementary angles are angles on the same side but one is between the parallel lines and one is outside of the parallel lines

16, According to the definition of supplementary angles, they are two angles that sum up to 180, and any two angles that are on the same line, same side and are being separated by a line are supplementary

17,

18, Corresponding angles are angles on the same side but one is between the parallel lines and one is outside of the parallel lines.

19, By the definition of Alternate Interior Angles, they are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal

20, By the definition of Alternate Exterior Angles, they are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

21, Vertical angles are angles opposite of each other made by two intersecting lines

22, 1, and 2 are supplementary angles so 180-35=145=1. 1 and 8 are Alternate Exterior Angles so 1=8, substitute, 145=8

Answer:

4 points

Step-by-step explanation:

.

Let  L  be the circumference of the circle.

Then the faster cyclist will catch the slower cyclist first time  when the faster cyclist will cover

the distance which exactly 1 circumference longer than the distance covered by the slower cyclist

9t-5t=l

It gives the time to get first meeting point

t=l/9-5=l/4 hours

and the distance which the faster cyclist covered during this time is

d1=9t=9l/4 miles

The distance which the slower cyclist covered during this time is

d2=5t=5l/4

The meeting point is geometrically the same point on the circle for both cyclists, and its angle measure on the circle is

 (1/l)(5l/(4)-l)=1/4

of the full angle of 2pi radians, or 90 degrees.

So, they started simultaneously, and their first meeting point is at the 90 degrees angle.

Next, they started from this point  SIMULTANEOUSLY  and . . . and everything was repeated.

Hence, their next meeting point is the point on the circle with the angle of 180 degrees.

So, there are 4 remarkable points on the circle: first point is the starting point, and 3 other points

(the points where whey meet/catch each other) are the images of the starting point, rotated 90°, 180°, and 270° along the circle.

There are 4 remarkable points on the circle which is the first point is the starting point and 3 other points.

The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

Let  L represent the circumference of the circle.

Then the faster cyclist will catch the slower cyclist the first time when the faster cyclist will cover the distance which is exactly 1 circumference longer than the distance covered by the slower cyclist

9t - 5t = L

It gives them time to get the first meeting point

t = L/9 - 5

t = L/4 hours

The distance which the faster cyclist covered during this time;

d1 = 9t = 9L/4 miles

The distance that the slower cyclist covered during this time is

d2 = 5t = 5L/4

The meeting point is geometrically the same point on the circle for both cyclists, and its angle measured on the circle;

(1/l)(5l/(4)-l)=1/4

Therefore, their next meeting point is the point on the circle with an angle of 180 degrees.

So, there are 4 remarkable points on the circle which is the first point is the starting point and 3 other points.

Answer:

Step-by-step explanation:

Let's solve:

[tex]p = \frac{hx}{5} [/tex]

Multiply both sides of the equation by 5 / h

[tex]p \times \frac{5}{h} = \frac{hx}{5} \times \frac{5}{h} [/tex]

[tex] \frac{5p}{h} = x[/tex]

Swap the sides of the equation

[tex]x = \frac{5p}{h} [/tex]

Answer:

  B.  -1.5x − 3.5y = -31.5

Step-by-step explanation:

You want an equation of the line perpendicular to -7x +3y = -21.5 that goes through the point (7, 6).

When the equation of the reference line is given in this form, the equation of a perpendicular line can be found by swapping the x- and y-coefficients, and negating one of them. Swapping coefficients, we have ...

  3x -7y = constant

Negating the x-coefficient gives ...

  -3x -7y = constant

Filling in the given point values, we can find the constant:

  -3(7) -7(6) = constant = -21 -42 = -63

None of the answer choices matches this, but one does match when we divide the numbers by 2:

  -3x -7y = -63

  -1.5x -3.5y = -31.5 . . . . . . matches choice B

Answer:

y = (-3/7)x + 9

Step-by-step explanation:

IF AB has the equation -7x + 3y = -21.5, then 3y = 7x - 21.5 is equivalent.  Dividing both sides by 3 yields y = (7/3)x - 21.5/3.  This reveals that the slope of AB is 7/3 and that the slope of any line perpendicular to AB, as central street PQ is, is the negative reciprocal of the slope of AB, or -3/7.

Thus PQ, being perpendicular to AB, has the slope -3/7.  Starting with y = mx + b, and using the coordinates of P(7, 6), we get:

6 = (-3/7)(7) + b, or 9 = b, so that y = (-3/7)x + 9.

Step-by-step explanation:

area of shaded region = 3168/7 - 55 = 397.5cm^2 (app)= 0.397cm^2 ( since we have to round to nearest hundredth

Answer:

The answer is

Step-by-step explanation:

To find the area of the shaded area first find the area of both the rectangle and the circle and subtract the smaller one from the larger one.

that's

For the rectangle

Area of rectangle = length × width

From the question

length = 5cm

width = 11 cm

So we have

Area of rectangle = 5cm × 11cm = 55cm²

For the circle

Area of a circle = πr²

where r is the radius

From the question

r = 12 cm

Area of circle = π (12)²

= 144π

= 452.40 cm²

Area of shaded figure

Since the area of the rectangle is smaller than that of the circle we subtract the area of the rectangle from the circle

That's

452.40 cm² - 55cm²

= 397.40 cm² to the nearest hundredth

Answer:

y = -x + 17

Step-by-step explanation:

A(-10,-3)

B(7,14)

C(5,12)

Need line CD perpendicular to AB through C.

Solution:

slope of AB, m1 = (yb-ya) / (xb-xa) = (14- -3) / (7- -10) = 17/17 = 1

Slope of CD, m2 = -1/m1 = -1 / 1 = -1
