Given parameters:

Cost per pound of Arabica coffee  = $28 per pound

Cost of Robusta coffee = $8.75

Given number of pounds of Robusta Coffee = 3 pounds

Total cost of blend per pound = $15.50

Unknown:

Number of pounds of Arabica coffee  = ?

Solution:

Let the number of pounds of Arabica coffee  = A;

  We have to interpret this problem algebraically and solve;

  28A + 8.75(3) = 15.5(A + 3)

Now solve the expression above for A;

       28A + 26.25 = 15.5A + 46.5

       28A - 15.5A  = 46.5 - 26.25

          12.5A = 20.25

                 A  = 1.62

Number of pounds of Arabica Coffee is 1.62 pound

Answer:

1.62 pound

Let's see what to do buddy...

_________________________________

STEP (1)

First we need to find the length.

(( length is two times the width ))

Length = 20 × 2 = 40 m

_________________________________

STEP (2)

Pearl will put wire around a rectangular.

Around of rectangular = Perimeter of it

So we must to find the perimeter of the rectangular.

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: p = 2(length + width) \\ \\ p = 2(20 + 40) \\ \\ \: \: \: \: p = 2 \times 60 = 120[/tex]

So Pearl needs 120 meters of wire.

And we're done.

Answer:

The  area is  [tex]A =  2827.8 \  ft^2 [/tex] of the park

Step-by-step explanation:

From the question  we are told that

  The  diameter of the garden is  d =  60 ft

Generally the radius of the circular garden with a path around it is mathematically represented as

    [tex]r =  \frac{60}{2}[/tex]

=>   [tex]r = 30 \  ft [/tex]

Generally the area of the park he will cover with plant food is mathematically represented as

        [tex]A =  \pi r^2[/tex]

=>      [tex]A =  3.142 *  (30 )^2[/tex]

=>      [tex]A =  2827.8 \  ft^2 [/tex]

Answer:

Measure of angle 2 and angle 4 is 42°.

Step-by-step explanation:

From the figure attached,

m∠ABC = 42°

m(∠ABD) = 90°

m(∠ABD) = m(∠ABC) + m(∠DBC)

90° = 43° + m(∠DBC)

m(∠DBC) = 90 - 43 = 47°

Since ∠ABC ≅ ∠4 [Vertical angles]

m∠ABC = m∠4 = 42°

Since, m∠3 + m∠4 = 90° [Complimentary angles]

m∠3 + 42° = 90°

m∠3 = 90° - 42°

        = 48°

Since, ∠5 ≅ ∠3 [Vertical angles]

m∠5 = m∠3 = 48°

m∠3 + m∠2 = 90° [given that m∠2 + m∠3 = 90°]

m∠2 + 48° = 90°

m∠2 = 90 - 48 = 42°

m∠3+ m∠4 = 90° [Since, ∠3 and ∠4 are the complimentary angles]

48° + m∠4 = 90°

m∠4 = 90 - 48 = 42°

Therefore, ∠2 and ∠4 measure 42°.

Step-by-step explanation:

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

Explanation:

Subtract the y coordinates: 9-3 = 6

Subtract the x coordinates in the same order: 10-5 = 5

Divide the differences:

slope = rise/run = (change in y)/(change in x) = 6/5

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

You could also use the slope formula

m = (y2-y1)/(x2-x1)

m = (9-3)/(10-5)

m = 6/5

Answer:

M=-10

Step-by-step explanation:

If 1 hour is 550 miles then 1 hour and 42 minutes would be 935 miles.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that,

1 hour = 550 miles

As we know,

1 hour = 60 minute

60 minute = 550 miles

1 minute = 550 miles / 60

1 minute =  9.16667 miles

42 minutes = 9.16667 miles

42 minutes = 385 miles

As a result,

1 hour and 42 minutes = 550 miles + 385 miles

1 hour and 42 minutes = 935 miles.

Thus, if 1 hour is 550 miles then 1 hour and 42 minutes would be 935 miles.

Step-by-step explanation:

Given that :

Sale price of blouse at 30% off = $22.76

Original price of blouse :

Let original price = p

(100 - 30)% of p = $22.76

0.7p = $22.76

p = $22.76 / 0.7

p = $32.51

= $32.50 ( to the nearest hundredth)

Step-by-step explanation:

Given parameters:

Number of chairs  = 3

Number of tables = 4

Cost of 3 chairs and 4 tables = Rs 7540

Price of 1 table = Rs220

Unknown:

Price of 1 table  = ?

Solution:

Let the cost of 1 table = t

 So,

        3(220) + 4(t) = 7540

         660 + 4t = 7540

         4t = 7540 - 660

          4t = 6880

            t = Rs. 1720

The cost of 1 table is Rs. 1720
