Answer:

24 inches represents 9 miles in the map

Step-by-step explanation:

To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:

8 ------- 3

x ------- 9

This is simply a rule of three, then you calculate:

[tex]x=\frac{8\ x\ 9}{3}=\frac{72}{3}=24[/tex]

Hence, 24 inches represents 9 miles in the map

Answer:

a. On the 13th day

b. 2,451 players we’re sold on that day

Step-by-step explanation:

a. The day in which the company sold the same number of players can be calculated by equating the values of y that we have ;

y = 191x-32 and y = -x^2 + 200x + 20

Equating both, we have;

191x-32 = -x^2 + 200x + 20

x^2 -200x + 191x-20-32 = 0

x^2-9x-52 = 0

x^2-13x + 4x -52 = 0

x(x-13)+4(x-13) = 0

(x-13)(x+4) = 0

x = 13 or -4

as days cannot be negative we choose only x = 13

This means the company sold equal numbers of players on the 13th day

b. To get the number of players sold on that day, we choose any of the y equation and substitute x = 13

Thus, we have for y = 191x -32; 191(13) - 32 = 2,451 players

Answer:

0.1667 = 16.67%.

Step-by-step explanation:

We already know that the card drawn is blue, so now we need to check the value of the card.

The blue cards have 6 possibilities of values (2, 3, 4, 5, 6 or 8), and the number 4 appears only 1 time, so the probability of the blue card having the value 4 is the number of times this value occurs by the number of possible values:

P = 1/6 = 0.1667 = 16.67%.

Answer:

26 blocks

Step-by-step explanation:

 To determine the number of blocks Tommy walked, you will calculate the distances between each of his points (ordered pairs).

Using the distance formula i.e[tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]

(0,0) to (0,6) is : [tex]\sqrt{(0-0)^2+(6-0)^2}[/tex] = 6 blocks  

(0,6) to (7,6) is: [tex]\sqrt{(7-0)^2+(6-6)^2}[/tex]= 7 blocks

(7,6) to (7,0) is: [tex]\sqrt{(7-7)^2+(0-6)^2}[/tex] = 6 blocks

(7,0) to (0,0) is: [tex]\sqrt{(0-7)^2+(0-0)^2}[/tex] = 7 blocks, back home

This totals 26 blocks that Tommy walked.

Answer:

-9.5116

Step-by-step explanation:

-1.58 * 6.02.

The easy way is to use your calculator.

To do it manually  you can multiply -158 by 2, then by 10 and then by 600.

Add these 3 results.

This gives -95116.

Now you have 4 numbers after the decimal point in -1.58 and 6.02 so counting from the right  in -95116 we locate the decimal point:

= -9.5116.

So the right answer is √314 units.

Answer:

length = 5 meters

width = 2 meters

Step-by-step explanation:

The volume of parallelepiped is given by:

Volume = length * width * height.

If the volume is 50 m3, the length is x + 3, the width is x and the height is 5 m, we can use the volume equation to find the value of x:

50 = (x+3) * x * 5

10 = (x+3) * x

x^2 + 3x - 10 = 0

Using Bhaskara's formula, we have:

Delta = 3^2 + 4*10 = 49

sqrt(Delta) = 7

x1 = (-3 + 7)/2 = 2

x2 = (-3 - 7)/2 = -5 (This value would cause negative measurements, so it is not a valid answer)

So with the value of x = 2, we can find the length and the width of the tank:

length = x + 3 = 2 + 3 = 5 meters

width = x = 2 meters

Answer:

The pressure exerted by gas number 3 is 159 mmHg

Step-by-step explanation:

To answer this question, the law to Use is Dalton’s law of partial pressure

Dalton’s law of partial pressure states that for a mixture of gases which do not mix, the total pressure exerted by such gases is equal to the sum of the individual pressure.

Now for the three gases, the total pressure Pt is equal to P1 + P2 + P3

Now we have Pt = 950 mmHg, P1 = 335 mmHg and P2 = 456 mmHg

P3 = Pt-P1-P2

Plugging the values above, we have ; 950-335-456 = 159 mmHg

Answer: Large box 1 can hold 64.67 inches; Large box 2 can hold 56.19 inches.

Step-by-step explanation:

Small box: 162 inches.

Large box 1: 10476 inches.

Large box 2: 9102 inches

Number of small box that can be contained in large box 1= 10476/162 = 64.67

Number of small box that can be contained in large box 2 = 9102/162 = 56.19

If my friend uses division to determine and said Large Box 1 can hold 64 small boxes and Large box 2 can hold 56 small boxes. The error in his reasoning was that he didn't approximated to whole number. He should have written the figure completely or to 2 or 3 decimal places.

The circumference of a circle is the distance around the outside of a circle. If we can find the circumference of the wheel, we can find out how far Elena can travel when her wheel turns one time.  If we can find out how far she travels in one wheel turn, we will multiply that distance by 840 to see how far she travels when her wheels turn 840 times.

Answer:

y = [tex]\frac{1}{2}[/tex] x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 3 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, - 3) into the partial equation

- 3 = 1 + c ⇒ c = - 3 - 1 = - 4

y = [tex]\frac{1}{2}[/tex] x - 4 ← equation of perpendicular line

An equation of the line that passes through points (2,−3) and is perpendicular to the line is equal to [tex]y=\frac{1}{2} x-4[/tex]

Given the following equation:

First of all, we would determine the slope of the given equation:

Slope, [tex]m_1[/tex] = -2

In Mathematics, the slopes of two lines are said to be perpendicular when the product of these slopes is equal to negative one (-1).

Mathematically, this is given by;

[tex]m_1 \times m_2 = -1[/tex]  

Substituting the value of [tex]m_1[/tex], we have:

[tex]m_1 \times m_2 = -1\\\\-2 \times m_2 = -1\\\\m_2 = \frac{1}{2}[/tex]

The standard form of an equation of line is given by the formula;

[tex]y -y_1 =m(x-x_1)[/tex]

Where:

Substituting the points into the formula, we have;

[tex]y-y_1 =m(x-x_1)\\\\y-[-3] =\frac{1}{2} (x-2)\\\\y+3=\frac{1}{2} x -1\\\\y=\frac{1}{2} x-1 -3\\\\y=\frac{1}{2} x-4[/tex]
