When graphing inequalities, where can the solutions be found?

Answers

Solutions will be located in the shaded region. Since this is a “less than” problem, ordered pairs on the boundary line are not included in the solution set. These values are located in the shaded region, so are solutions. (When substituted into the inequality x–y<3.

When solving systems of inequalities, the solutions are the regions where all the inequalities are true and will be represented by the intersection of the shaded areas.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

When graphing inequalities, the solutions can be found on the side of the number line or the coordinate plane where the inequality is true.

For example, if the inequality is x > 3, the solutions would be all the values of x that are greater than 3. These solutions would be represented by shading the area to the right of line x = 3 on the coordinate plane.

Similarly, if the inequality is y < 2, the solutions would be all the values of y that are less than 2. These solutions would be represented by shading the area below the line y = 2 on the coordinate plane.

It's important to note that when solving systems of inequalities, the solutions are the regions where all the inequalities are true and will be represented by the intersection of the shaded areas.

Seema sells two cookers for Rs.2574 each. On one she gains 10% and on the other she loses 10%.Find her gain or loss percent in the whole transaction.​

Answers

Answer:

18.18%

Step-by-step explanation:

Selling price of one coker = Rs.2574

If she loose 10% on one;

%loss = Cost price - Selliing price/cost price * 100

10 =Cp-2574/Cp * 100

10/100 = Cp-2574/Cp

0.1Cp = Cp-2574

0.1Cp - Cp = -2574

-0.9Cp =  -2574

Cp = 2574/0.9

Cp = Rs. 2860

Amount lost = 2860-2574 = Rs. 286

If she gains 10% on the second

%loss =Sp-Cp/Cp * 100

10 = 2574-Cp /Cp * 100

10/100 = 2574-Cp /Cp

0.1Cp = 2574-Cp

1.1Cp = 2574

Cp = 2574/1.1

Cp = Rs. 2340

Amount gained = 2340-2574 = Rs. 234

Total Loss = Amount lost - Amount gained

Total loss = 286 - 234

Total loss = Rs. 52

Total loss % = 52/286 * 100

Total loss % = 5200/286

Total loss % = 18.18%

09) The ratio of the number of jackfruit in baskets P, Q

jackfruit in basket Q. Calculate the total number
of jackfruits in the three baskets.
A 121 B 144 C 156 D 169​

Answers

Answer:

156 jackfruits

Step-by-step explanation:

Let there are 6x jackfruit in baseket P, 2x in basket Q and 5x in basket R.

The total number of jackfruit  in basket P is 48 more than the number of  jackfruit in basket Q. ATQ,

6x = 48 + 2x

Solving for x.

6x - 2x = 48

4x = 48

x = 12

Jackfruits in basket P = 6x = 6(12) = 72

Jackfruits in basket Q = 2x = 2(12) = 24

Jackfruits in basket R = 5x = 5(12) = 60

Total no of jackfruits = 72 + 24 + 60

= 156

So, there are 156 jackfruits in the three baskets.

Container A and container B have leaks. Container A has 800 ml of water, and is

leaking 6 ml per minute. Container B has 1000 ml, and is leaking 10 ml per minute.

How many minutes will it take for the two containers to have the same amount of

water?

**Write an equation to represent the situation (first blank). Use the variable m, for

minutes.

**Then solve for m (second blank).

**Finally, use your solution to determine the water level at that time (third blank).

The equation

can represent this situation. It will take

minutes for the two containers to have the same amount of water. At this time,

both containers will have ml left.

Answers

Answer:

a) 50 minutes

b) The water level at 50 minutes for Container A and B would be 500ml

Step-by-step explanation:

a) Let number of minutes at which both containers leak be represented by m.

Container A has 800 ml of water, and is leaking 6 ml per minute.

800ml - 6ml × m

800 - 6m

Container B has 1000 ml, and is leaking 10 ml per minute.

1000ml - 10ml × m

1000 - 10m

How many minutes will it take for the two containers to have the same amount of water?

Container A = Container B

800 - 6m = 1000 - 10m

Collect like terms

-6m + 10m = 1000 - 800

4m = 200

m = 200/4

m = 50 minutes

It will take 50 minutes for the two containers to have the same amount of water.

b) Finally, use your solution to determine the water level at that time.

Since m = 50 minutes

Container A = Container B

800 - 6m = 1000 - 10m

800 - 6 × 50 = 1000 - 10 × 50

800 - 300 = 1000 - 500

500 ml = 500 ml

Therefore, the water level at 50 minutes is 500 ml

14. A satellite orbits 22, 300 miles above the equator. It completes one revolution in 24 hours. Assume that the radius of the Earth is 3, 960 miles. How far will the satellite travel in one day?​

Answers

Answer:

Displacement = 0 mi

Distance = 164,996.45 mi

Step-by-step explanation:

In this case, the displacement will be zero because the satellite goes back to its starting point after one day. If there is no distance traveled between the starting point and the ending point, then the Displacement will be zero.

When it comes to the distance, we will need to calculate the perimeter of the circle the satellite describes when making one whole turn around the earth.

The perimeter of a circle is given by the equation:

[tex]p=2\pi r[/tex]

so we need to start by finding what the radius of the circle is. This radius if found by adding the radius of the earth and the distance above the equation the satellite is located at, so we get that:

[tex]r=r_{earth}+h[/tex]

where h is the height of the satellite, so the radius of the circle is:

[tex]r=22,300mi + 3,960 mi[/tex]

so

r=26,260 mi

so now we can use the perimeter equation to get:

[tex]p=2\pi r[/tex]

[tex]p=2\pi (26,260)[/tex]

So the distance traveled by the satellite in one day will be:

P=164,996.45 mi.

1. 21
2. 22
3. 23
4. 24

Answers

3 is the correct answer

The quotient is 21. the correct answer is option 1) 21.

To find the quotient of 189 divided by 9, we divide 189 by 9.

When dividing 189 by 9, we find that 9 can be subtracted from 189 a total of 21 times without going into negative values. Therefore, the quotient is 21.

So, the correct answer is option 1) 21.

When we divide 189 by 9, the result is 21, which means that 21 is the number of times that 9 can be subtracted from 189 without remainder. The quotient represents the whole number part of the division, indicating the number of groups of 9 that can be formed from 189.

Johny and Rahul divided the benefit of the business in the ratio 7:9. If
Rahul got 4878 rupees as benefit did Johny get?

Answers

Answer:

Step-by-step explanation:

7:9 = x:4878

4878/9 times 7

3794 would be your answer

Answer:

3,794 rupees

Step-by-step explanation:

Johny got 7 parts of the benefit while Rahul got 9. This can be represented as a fraction: 7/9

To solve this problem, we can use cross multiplication, where x represents the amount of rupees Johny got:

[tex]\frac{7}{9}[/tex] = [tex]\frac{x}{4878}[/tex]

Multiply 7 by 4,878: 34,146

Multiply 9 by x: 9x

Now the equation looks like this:

9x = 34,146

Divide both sides of the equation by 9 to isolate the x:

9x/9 = 34,146/9

x = 3,794

Johny got 3,794 rupees.
