Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

88 ft/s= 60 miles/hr

Required

Determine the equivalent of 1 mile/hour

88\ ft/s= 60\ miles/hr

Express 60 as 60 * 1

88\ ft/s= 60 * 1\ mile/hr

Divide both sides by 60

\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}

\frac{88\ ft/s}{60}= 1\ mile/hr

Reorder

1\ mile/hr = \frac{88\ ft/s}{60}

Divide 88 by 60

1\ mile/hr = 1.46666666667\ ft/s

Approximate to 3 significant figures

1\ mile/hr = 1.47\ ft/s

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds

COSINE LAW: Solve triangle PQR. round angles to the nearest tenth​
Valentin [98]

Answer:

Hi,

Step-by-step explanation:

PR²=PQ²+QR²-2*PQ*QR*cos(51°)

=15²+12²-2*15*12*cos(51°)

=142,444659....

PR=11.9350...

PQ²=QR²+PR²-2*QR*PR*cos(R)

cos(R)=(12²+142.444...-15²)/(2*12*11.9350...)=0,21451112....

angle R=77,61315...°≈77.6°

angle P=180°-51°-77.6°≈51,4°

Solve using system by elimination:<br> -3x + 4y = -18<br> x = -2y - 4
Jet001 [13]

Step-by-step explanation:

equation 1 : -3x + 4y = -18

equation 2: x = -2y -4

transformed equation 2: x + 2y = -4

-3x + 4y = -18

x + 2y = -4

By elimination means we have to make one variable equal to zero or we have to take one variable out of the whole equation.

Let's eliminate the variable x. To do so, let's multiple the second equation to +3. Therefore,

-3x + 4y = -18

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

-3x + 4y = -18

3x + 6y = -12

Now that both equations have the same value of x but different signs, we can now eliminate x by adding the two equations.

-3x + 4y = -18

<u>3x + 6y = -12</u>

<u> </u> 0 + 10y = -30

Dividing both sides by 10, we have y = -3.

Now that we have the value of y, we can just substitute the value of y into either one of the equation OR we can do the process again but this time we need to eliminate y to find the value of x.

-3x + 4y = -18

x + 2y = -4

To eliminate y, we need to multiply the second equation by -2.

-3x + 4y = -18

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

-3x + 4y = -18

-2x - 4y = 8

Now that we have the same values but different signs of y, we can now add the two equations again.

-3x + 4y = -18

<u>-2x - 4y = 8</u>

-5x + 0 = -10

Dividing both sides by -5, we have x = 2.

CHECKING:

Let's take the second original equation,

x = -2y -4

Let's substitute the values we have found into the equation:

2 = -2(-3) - 4

2= 6 - 4

2 = 2

Both sides of the equation produced the same values. Therefore, the values are correct.

A company’s profit, P, in dollars, for producingx machines in one day is given by P = 500x - 20x*2.If the company produces 10 ma
Slav-nsk [51]

The profit of that day is (C) P = $3,000.

<h3>What is profit?</h3>
  • A profit is a difference between the revenue generated by an economic entity's outputs and the opportunity costs of its inputs.
  • Total revenue minus total cost, including both explicit and implicit costs, equals total revenue.
  • Unlike accounting profit, it only refers to the explicit costs that appear on a company's financial statements.
  • Accounting profit is calculated by subtracting the firm's total revenue from only the firm's explicit costs.
  • When analyzing a firm, an economist considers all opportunity costs, both explicit and implicit.

To find the profit of that day:


Given:

  • P = 500x − 20x², where 'x' is the number of machines per day produced.
  • If the company produces 10 machines in one day, that is x = 10.

By substituting x = 10 in the above equation, we get:

  • P = 500 × 10 - 20 × 10²
  • P = 5000 - 2000
  • P = 3,000/

Therefore, the profit of that day is (C) P = $3,000.
