What is the answer for ?x+2y=4 3x+6y=18

Step-by-step explanation:

the area of a circle (all 360°) is

pi×r²

with r being the radius.

the area of a circle segment is just the corresponding fraction of the whole circle.

so the area of a segment of x degrees is

pi×r² × x/360

in our case we know

pi×42240² × x/360 = 180 mi²

we also know that there are 5280 ft in 1 mile.

so, the radius is actually

42240 / 5280 = 8 miles

and therefore our equation resulting in mi² has to use miles and not ft and has to look that way :

pi×8² × x/360 = 180 mi²

pi×64 × x/360 = 180

pi×64 × x = 180×360

pi×x = 180×360/64 = 1012.5

x = 1012.5/pi = 322.2887598...°

so, the angle of the segment of a circle with the area of 180 mi² and the radius of 8 mi is 322.2887598...°

Strategies such as fast-tracking, crashing, prioritization, and resource optimization can be employed to reduce the project completion time by 5 weeks.


To reduce the completion time of the project by 5 weeks, we need to analyze the provided information and make appropriate adjustments. The initial completion time of the project is 25 weeks.

To achieve a reduction of 5 weeks, we can consider several strategies:

1. Fast-tracking: This involves overlapping or parallelizing certain project activities that were initially planned to be executed sequentially. By identifying tasks that can be performed concurrently, we can potentially save time. However, it's important to evaluate the impact on resource allocation and potential risks associated with fast-tracking.

2. Crashing: This strategy focuses on expediting critical activities by adding more resources or adopting alternative approaches to complete them faster. By compressing the schedule of critical tasks, we can reduce the overall project duration. However, this may come at an additional cost.

3. Prioritization: By reevaluating the project tasks and their priorities, we can allocate resources more efficiently. This ensures that critical activities receive higher attention and are completed earlier, resulting in an accelerated project timeline.

4. Resource optimization: Analyzing the resource allocation and identifying potential areas for optimization can lead to time savings. By ensuring that resources are utilized effectively and efficiently, we can streamline the project execution process.

It's important to note that implementing any of these strategies requires careful evaluation, considering factors such as project constraints, risks, cost implications, and stakeholder agreements. A comprehensive analysis of the project plan, resource availability, and critical path can guide the decision-making process for reducing the project completion time.

There are 35 possibilities (probability) to choose the four individuals who will be interviewed out of the seven college students that have applied for internships at a local company.

The field of mathematics known as probability studies numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, with 0 generally signifying the event's impossibility and 1 generally signifying its certainty. As an event's probability rises, so does the possibility that it will happen. An easy example is tossing a coin in a fair (unbiased) manner. Since the coin is fair and there are no other possible outcomes, the probability of either "heads" or "tails" is half, indicating that both possibilities are equally likely.

Given statement solution is :- (a) 1 route is possible from A to P.

(b) 1 route is possible from A to P with a stop at C.

(c) 1 route is possible from A to P with stops at both C and S.

To determine the number of possible routes from point A to point P, we can use the concept of combinations and permutations. Assuming each intersection on the map is a distinct point, and the driver can only travel south or east, we can consider this as a grid problem.

(a) Without any additional stops:

In this case, the driver can only travel south or east until they reach point P. Since the driver cannot backtrack, there is only one path to reach point P from A. Therefore, the answer to part (a) is 1.

(b) If you insist on stopping off at the Chipotle at C:

In this case, the driver needs to pass through point C before reaching point P. We can break down the problem into two parts: the number of routes from A to C and the number of routes from C to P.

From A to C:

Since the driver can only travel south or east, there is only one path to reach point C from A.

From C to P:

Similarly, there is only one path to reach point P from C.

Therefore, the answer to part (b) is 1 (from A to C) multiplied by 1 (from C to P), which equals 1.

(c) If you wish to stop off at both the Chipotle at C and the Sonic at S:

In this case, we can again break down the problem into three parts: the number of routes from A to C, the number of routes from C to S, and the number of routes from S to P.

From A to C:

There is one path from A to C.

From C to S:

Since the driver can only travel south or east, there is only one path from C to S.

From S to P:

Similarly, there is only one path from S to P.

Therefore, the answer to part (c) is 1 (from A to C) multiplied by 1 (from C to S) multiplied by 1 (from S to P), which equals 1.

In summary:

(a) 1 route is possible from A to P.

(b) 1 route is possible from A to P with a stop at C.

(c) 1 route is possible from A to P with stops at both C and S.

The part labelled A is 26 tens

The part labelled B is 13 units

The part labelled C is 13 ones

information given in the question

A rectangle is divided into two sections by a vertical line

The left section is labeled inside with 260

The left edge of the rectangle is labeled 13

other information is in the attached diagram

How to used the model

Carter's model is a rectangle of length 273 and breadth 13.

273 / 13 = 21

This means that dividing the length into 13 places each unit is 13

273 - 13 = 260

hence the 260 represents 20 units, since one unit is subtracted

The knowledge of place value help to get the numbers to be arranged in tens and ones

putting the numbers in tens is done by dividing by 10

= 260 / 10

= 26

hence, A in tens is equivalent to 26

putting the numbers in ones is dine by dividing by 1

C = 13 / 1

C = 13 ones

a unit is 13, B = 13

The value of resistor R4 is 0.5 minus the sum of resistors R1, R2, and R3.

We have,

To find the value of resistor R4, we can use Ohm's Law and the formula for calculating the total resistance in a series circuit.

In a series circuit, the total resistance (R_total) is the sum of the individual resistances:

R_total = R1 + R2 + R3 + R4

We are given that a voltage of 50 V is applied and a current of 100 A flows through the circuit.

Using Ohm's Law (V = I * R), we can calculate the individual voltage drops across each resistor:

V1 = I x R1

V2 = I x R2

V3 = I x R3

V4 = I x R4

Since the voltage across each resistor is equal to the total applied voltage (50 V), we can write the following equations:

V1 + V2 + V3 + V4 = 50

Substituting the voltage values using Ohm's Law:

(I x R1) + (I x R2) + (I x R3) + (I x R4) = 50

Simplifying the equation:

I x (R1 + R2 + R3 + R4) = 50

Substituting the given values for the current (I = 100 A) and resistors R1, R2, and R3:

100 x (R1 + R2 + R3 + R4) = 50

Solving for R4:

R1 + R2 + R3 + R4 = 50/100

R4 = 0.5 - (R1 + R2 + R3)

Therefore,

The value of resistor R4 is 0.5 minus the sum of resistors R1, R2, and R3.

The tip of the minute hand moves about 83.8 inches in 50 minutes.

The minute hand of a clock is 8 inches long.

How far does the tip of the minute hand move in 50 minutes:

The circumference of the clock is the distance traveled by the tip of the minute hand for 1 minute, given that the clock has 12-hour marks on its periphery.

Here is a detailed explanation of the problem:

Since the length of the minute hand is 8 inches, the radius of the clock is also 8 inches.

C = 2πr (Circumference of the clock)C = 2 × π × 8C = 16π inches (Circumference of the clock)

The minute hand of the clock covers the circumference of the clock in 60 minutes.

Thus, in 1 minute, the minute hand will travel 1/60th of the clock's circumference.

The distance the minute hand covers in 50 minutes is the product of the distance covered in 1 minute by the number of minutes that is 50.

Coverage of the minute hand in 1 minute = (1/60) × (16π) = (4π)/15 inches.

Coverage of the minute hand in 50 minutes = 50 × [(4π)/15] inches.

Simplifying the expression gives;

Coverage of the minute hand in 50 minutes = (400π)/15 inches ≈ 83.8 inches (rounded to one decimal place).

Step-by-step explanation:

The given statement "if set of difference scores with df = 8 has a mean of md = 3.5 then sample will produce repeated-measures t statistic of t = 1.75." is false because  it is not possible to determine t statistic.

In a repeated-measures t-test, the t statistic is calculated using the sample mean difference, the standard deviation of the sample mean difference, and the sample size. The formula for calculating the t statistic in a repeated-measures t-test is:

t = (md - μd) / (s / √n)

where md is the mean of the difference scores, μd is the population mean of the difference scores (typically assumed to be zero), s is the standard deviation of the difference scores, and n is the sample size.

In the given statement, we are provided with the mean of the difference scores (md = 3.5) and the variance (s² = 36), but we do not have the sample size (n). Therefore, we cannot calculate the t statistic using the given information.

\(Weight = \frac{23}{2}\)

Step-by-step explanation:

Given

Weight of Pinata = 11/4 lb

Weight of candies = 3/8, 3/8, 1/2 , 1/2, 1/2, 3/4, 3, 11/4

Required

Weight of Pinata when filled with candies

To solve this question, we simply need to add all weights together

First, we need to add up the weight of the candies

\(Candies = \frac{3}{8} + \frac{3}{8} + \frac{1}{2}+ \frac{1}{2}+ \frac{1}{2}+ \frac{3}{4} + 3 + \frac{11}{4}\)

Take LCM

\(Candies = \frac{3 + 3 + 4 +4 + 4 + 6 + 24 + 22}{8}\)

\(Candies = \frac{70}{8}\)

Simplify:

\(Candies = \frac{35}{4}\)

Next; Add the weight of the candies to the weight of pinata

\(Weight = Candies + Pinata\)

\(Weight = \frac{35}{4} + \frac{11}{4}\)

Take LCM

\(Weight = \frac{35 + 11}{4}\)

\(Weight = \frac{46}{4}\)

Simplify

\(Weight = \frac{23}{2}\)

Hence, the weight of the Pinata after it is filled with candies is 23/2 lb

Step-by-step explanation:

Paul is making bread using a recipe. The amount of flour he uses is proportional to the number of loaves of bread. He uses 11 1/4 cups of flour to make 5 loaves of bread. If Paul used 18 cups of flour, and then sold the loaves of bread he made at a bake sale for $2.50 each, how much money would Paul make from his bread sales?

Step 1

Find out how many loaves of bread he can produce from 18 cups of flour

11 1/4 cups of flour = 5 loaves of bread

18 cups of flour = x loaves of bread

Cross Multiply

11 1/4 cups × x loaves = 18 cups × 5 loaves

x loaves = 18 cups × 5 loaves/ 11 1/4 cups

x loaves = 90 ÷ 11 1/4

x loaves = 90 ÷ 45/4

x loaves = 90 × 4/45

x loaves = 8 loaves of bread

He can produce 8 loaves of bread from 18 cups of flour.

Step 2

We are told that:

1 loaf of bread costs $2.50

Hence,

1 loaf of bread = $2.50

8 loaves of bread = $x

Cross Multiply

$x = 8 loaves of bread × $2.50

$x = $20

Therefore, Paul made $20 from his bread sales
