Answer:

Therefore, you need 2600 pounds of 35% supplement and 1300 - 2600 = -1300 pounds of 10% ration.

Step-by-step explanation:

The unknown variable is x, which is the amount of 35% supplement needed. The other expressions are derived from the given information and the fact that the total amount of solution is 1300 pounds.

The equation from the fourth column is:

0.35x + 0.10(1300 - x) = 0.25(1300)

Solving for x, we get:

x = (0.25(1300) - 0.10(1300)) / (0.35 - 0.10) x = 650 / 0.25 x = 2600

The minimum length of pipe required to deliver water to points A and B is approximately 20.375 miles.

We are given that a water pumping station is to be built on a river at point P in order to deliver water to points A and B. The design requires that LAPD = /BPC so that the total length of piping that will be needed is a minimum. We need to find this minimum length of pipe.

The given figure is shown below: \(AB = 10 \ miles\)\(BC = 6 \ miles\)\(CP = 12 \ miles\). We are given that \(LAPD = LCPB\).

Now, we need to find the minimum length of pipe required for delivering the water to points A and B.The total length of the pipe, \(L_{total} = LA + AB + BP\)Since \(LAPD = LCPB\), we can say that\(AP^2 + PD^2 = BP^2 + PC^2\).

From the triangle ACP, we can say that\(AC^2 = AP^2 + PC^2\). So, we can substitute AP^2 + PC^2 with AC^2 to get\(AP^2 + PD^2 = BP^2 + AC^2\)Now, we can substitute AP = AC - PC and BP = BC + PC in the above equation to get\((AC - PC)^2 + PD^2 = (BC + PC)^2 + AC^2\).

After solving this equation, we get\(AC = \frac {37}{8}\) and \(PC = \frac {27}{8}\)Now, we can calculate the length of pipe required as follows: \(L_{total} = LA + AB + BP = 10 + 6 + \frac {27}{8} = \boxed{20.375 \ miles}\). Therefore, the minimum length of pipe required to deliver water to points A and B is approximately 20.375 miles.

Missing Information

Suppose the officials conducted a survey for 4 days to determine the actual number of families residing in the barangay and the secretary constructed a tableto keep track of the data.

Day 0:

Number of families: 850

Amount of relief each family will receive: 520

Answer:

f(x) = 442000/x

Step-by-step explanation:

Given

The data in the above table

Required

Determine a model or equation

First, we need to determine the amount of relief for all families.

Using data in day 0.

Total Amount = 850 * 520

Total Amount = 442000

Next, we determine the function of equation.

Let the number of families he represented by x

The function or equation is gotten by dividing the total amount by the number of families.

Hence:

f(x) = Total Amount ÷ x

Substitute values for total amount and x

f(x) = 442000/x

Hence, the model that satisfies the given information is:

f(x) = 442000/x

Step-by-step expl4anation:

The system of linear equations y = x - 6.7 and y = - x + 1.7 have solution at point (x, y) = (4.2, - 2.5).

In this problem we need to construct a system of two linear equations whose solution is point (x, y) = (4.2, - 2.5). Linear equations are algebraic equations of the form:

y = m · x + b

Where:

The procedure is shown below. First, obtain the intercept of the first equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = 1)

b = - 2.5 - 4.2

b = - 6.7

Second, write the first linear equation:

y = x - 6.7

Third, find the intercept of the second equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = - 1)

b = - 2.5 - (- 1) · (4.2)

b = - 2.5 + 4.2

b = 1.7

Fourth, write the second linear equation:

y = - x + 1.7

Answer:

355,459.33

Step-by-step explanation:

42,655.12/12 = 3554.59

3554.59*100 = 355459.33

The actual price of the home is $355,459.33.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100. Percentage is usually denoted by the symbol '%'.

Down payment is the initial payment made when we are buying expensive things like house or car.

Let x be the actual price of the house.

Percentage of down payment = 12% = 12/100 = 0.12

Amount of down payment = $42,655.12

12% of x = 42,655.12

0.12 x = 42,655.12

x = 42,655.12 / 0.12

x = 355,459.333 ≈ 355,459.33

Hence the price of the home to the nearest cent is $355,459.33.
