Answer:

1. There is no change in the number of state representatives for fourth state after the last census.

2.  We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.

36 in sq, because a rectangle has even sides on both so it’s 12 + 12 + 6 + 6

Answer:

84 square cm.

Step-by-step explanation:

The area of the rectangle: 12*6=72

The area of one right triangle: 1/2(2*6)=6

Since we have two right triangles, their area combined: 6*2=12

Add 72+12= 84 square cm.

A video game is on sale at Amazon for 35% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They will have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.

Pat takes 35% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.

Henri finds 65% of the original price and then calculates 110% of the sale price.



Will Pat's strategy calculate the correct total? Explain the calculations.

Will Henri's strategy calculate the correct total? Explain the calculations.

Do they each have enough to purchase the game?

Explain your answers using complete sentences and show your work.

Answers

Answer:

yes pat will, because he is taking 35% off of the original price to get the sales price. no henry wont, because the total is supposed to go down not up. no they will not be able to buy 1 for each of them because 1 game costs $18.70

Step-by-step explanation:

28.50/100=0.285

0.285=0.28

0.28*35=9.80

28.50-9.80=18.70

What is the approximate radius of a sphere with a volume of 1436 cm^3?

Answers

Answer: 7 cm

Step-by-step explanation:

The approximate radius of a sphere with a volume of 1436 cm³ will be 7 cm.

What is the volume of the sphere?

Let r be the radius of the sphere.

Then the volume of the sphere will be

V = 4/3 πr³ cubic units

The volume of the sphere will be 1463 cm³.

Then the radius will be

    1436 = 4/3 πr³

    1077 = πr³

342.82 = r³

          r = 6.998

          r ≈ 7 cm

Answers

Answer:

210 is the number of midsized cars

Step-by-step explanation:

Assume x is the number of midsized cars

So you can create the equation 70/100=x/300

(300*70)=100x

21000=100x

How many solutions does this linear system have? y = 2x – 5 –8x – 4y = –20 one solution: (–2.5, 0) one solution: (2.5, 0) no solution infinite number of solutions

Answers

Answer: b. one solution: (2.5, 0).

Step-by-step explanation:

y = 2x - 5

-8x - 4y = -20

-8x - 4y = -20

-8x - 4 * (2x - 5) = -20

-8x - 8x + 20 = -20

20 + 20 = 16x

16x = 40

x = 40/16

x = 2.5   y = 2x - 5 = 2 * 2.5 - 5 = 5 - 5 = 0

(x, y) = (2.5, 0)

The system of equations will have a unique solution (2.5, 0)

What is system of equations?

A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations.

Given is a system of linear equations y = 2x-5 and -8x-4y = -20

y = 2x-5......(i)

-8x-4y = -20

Rearranging the equation,

8x+4y = 5

2x+y = 20

y = 20-2x.......(ii)

Solving the equation,

20-2x = 2x+5

15 = 4x

x = 2.5

Put x = 2.5 in eq(i)

y = 2(2.5)-5

y = 0

Now, determining how many solutions do this system has,

Ratios of the coefficient,

1/1, 1/4, -1

Since, 1/1 ≠ -1

Therefore, the system of the equation has only one solution.

Hence, the system of equations will have a unique solution (2.5, 0)
