the total economic investment by BBQ is $(10 +2=)12 million and purely financial investment accounts for $6 million.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given,a national restaurant chain called BBQ builds 10 new restaurants at a cost of $1 million per restaurant.

Economic investment is the amount of money used to increase the productivity or output of the economy. Since BBQ builds 10 new restaurants at the cost of $1 million per restaurant, the total capital investment in all restaurants by BBQ is $1 million × 10 = $10 million.

Also, the BBQ makes an additional investment of $200,000 in each restaurant to increase the productivity of restaurants. Therefore, total economic investment in all the restaurants is

$200,000 × 10 = $2,000,000.

Hence, the total economic investment by BBQ is $(10 +2=)12 million.

Financial investment by BBQ

The financial investment includes investments in bonds, shares, real estate, or any financial assets. The cost per share is $30, and the total number of shares issued is 200,000.

Thus, the total funds raised from shares are

$30 × 200,000 = $6,000,000.

Therefore, purely financial investment accounts for $6 million.

Pat and John will meet in 3 hours.

Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

here, we have,

How to calculate the value?

It should be noted that speed = Distance / Time

The appropriate equation will be:

80t + 24t = 312

104t = 312

t = 312/104

Answer:

93.75min

Step-by-step explanation:

Solution:

The rate of fill up is, Rate = 3.2 Gallons / minute = 3.2 g/min

The hut tub volume is 300 Gallons

You can set up this problem as follows:

Every 3.2 gallons require 1 minute, How many minutes 300 gallons require?

3.2  g    1min

300 g     ? min    = (300 gallons x 1min/ 3.2 gallons)=(300/32)min

= 93.75 min

or simply the number minutes is the time required (T) the rate is (R) and the volume is (V)

such that T=V/R= (300g/3.2 g/min)= 93.75 min

Rosa's change in elevation, relative to the diving board, in meters during the dive, which is a measure of her displacement, is -5.8 meters.

Displacement is the change in the position of an object, with regards to a frame of reference. Displacement is a vector quantity, that has both magnitude and direction, indicated by the sign (positive or negative), and the magnitude, which is the measured value.

The height of the diving board above the surface of the water = 3 meters

The depth to which Rosa descends relative to the water surface = -2.3 meters

Therefore, Rosa's initial elevation when on the diving board = 3 meters

Rosa elevation when at the depth to which she dives = -2.8 meters

Her change in elevation can be obtained by finding her displacement from the diving board, when she descends to the depth of -2.8 meters.

Rosa's change in elevation, Δh = Final elevation - Initial elevation

Therefore, Δh = -2.8 m - 3 m = -5.8 m

Answer:

The answer is 768.0 square inches.

Step-by-step explanation:

The surface area of a square pyramid can be calculated by adding the area of its four triangular faces to the area of its base, which is a square.

First, we'll find the area of the base:

24 inches x 24 inches = 576 square inches

Next, we'll find the area of each triangular face:

1/2 * 24 inches * 20 inches = 240 square inches

So, the total surface area of the pyramid is:

576 square inches + 4 * 240 square inches = 1,536 square inches

Finally, we'll find the surface area that is yellow:

1,536 square inches / 2 = 768 square inches

Rounding to the nearest tenth, we have:

768 square inches = 768.0 square inches

So, the surface area of the toy that is yellow is 768.0 square inches.

Answer: $675

Step-by-step explanation:

To calculate the monthly payment, we need to determine the number of $2,000 increments that the car costs. $30,000 ÷ $2,000 = 15.

So, the car costs 15 $2,000 increments.

Next, we need to multiply the number of increments by the $45 increase in payment per increment to find the monthly payment. 15 increments × $45/increment = $675.

Therefore, the monthly payment for a $30,000 car would be $675.

The inventory can the firm purchase without violating its debt agreement is $777,777

Liquidity ratios are a class of financial metrics used to determine a debtor's ability to pay off current debt obligations without raising external capital.

Given that, Ronaldinho Trading Co. is required by its bank to maintain a current ratio of at least 1.75, and its current ratio now is 2.1.

Let X represent the additional borrowing against the firm’s line of credit (which also equals the addition to current assets).

We can solve for that level of X that forces the firm’s current ratio to be at 1.75

$3,500,000 / Current liabilities = 2.1

Current liabilities = $1,666,667

1.75 = ($3,500,000 + X) / ($1,666,667 + X) (1.75 * $1,666,667) + 1.75X

= $3,500,000 + X 0.75X = $3,500,000 – $2,916,667 X

To prove: p V q

Assume ~p V q is true (as the antecedent of the implication)

Since ~p V q is true, either ~p is true or q is true.

If ~p is true, then p is false, but the disjunction p V q is true.

If q is true, then the disjunction p V q is true.

Step-by-step explanation:

The least number of square yards of paper required to make the poster is 11 square yards.

The area of a rectangle can be found by multiplying the length of its sides. To find the length and width of the rectangle, we can subtract the x and y values of the opposite vertices.

The length of the rectangle is 34 - 2 = 32 inches, and the width is -44 - 4 = -48 inches. We will have to make the width positive to find the area, so the area is 32 * 48 = 1536 square inches.

Since 1 square yard is equal to 144 square inches, we need to divide 1536 by 144 to find the number of square yards: 1536 / 144 = 10.67 square yards.
