Answer: 35 chocolates were bought and 52 gums were bought.

Step-by-step explanation:

c + g = 87    where c is the number of chocolate and g is the number og gums

1.50c + 0.50g = 78.50    solve both equations by elimination.

-1.50c - 1.50g =  -130.5

1.50   + 0.50g = 78.50

           -1g =  -52

             g= 52

1.50c + 0.50(52) = 78.50

 1.50c + 26 = 78.50

             -26     -26

1.50c = 52.5

c = 35  

Answer:

x = [tex]\frac{3}{7}[/tex], x = [tex]\frac{-3}{7}[/tex]

Step-by-step explanation:

The first step is to get rid of the square on the x, and to get rid of it, you square root both sides of the equation, like so:

[tex]x^{2} = \frac{9}{49}[/tex]

[tex]\sqrt{x^2} = \sqrt{\frac{9}{49} }[/tex]

A perfect square is when a number has two factors that are identical to one another. In this case, 9 and 49 are both perfect squares, meaning we can break them down:

The square root of 9 is 3. (3 · 3 = 9)

The square root of 49 is 7. (7 · 7 = 49)

x = [tex]\frac{3}{7}[/tex]

The answer is also x = [tex]\frac{-3}{7}[/tex] because a negative · a negative = a positive.

Answer:

The area of this sector is 224*pi cm² or approximately 703.72 cm²

Step-by-step explanation:

In order to calculate the area of a sector for which we have an angle in radians, we need to apply a rule of three in such a way that pi*r² is related to 2*pi radians in the same proportion as the given angle is related to the area of the sector we want to find. This is shown below:

2*pi rad -> pi*r² unit²

angle rad -> sector area unit²

2*pi / angle = pi*r² / (sector area)

2*pi*(sector area) = pi*r²*angle

sector area = [pi*r²*angle]/2*pi

sector area = r²*angle/2 unit²

Applying the data from the problem, we have:

sector area = [(16)²*(7*pi/4)]/2 = [256*(7*pi/4)]/2 = 64*7*pi/2 = 32*7*pi = 224*pi

sector area = 224*pi cm²

sector area = 703.72 cm²

Answer:

Since [tex]P(A \cap B) \neq P(A)P(B)[/tex], these events are not independent.

Step-by-step explanation:

Independent events:

Two events, A and B are independent, if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

In this question, we have that:

[tex]P(A) = 0.4, P(B) = 0.2, P(A \cap B) = 0.1[/tex]

Answer: (-2, -1)

Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.

The two lines intersect in quadrant III

where x and y are both negative.

When finding the coordinates of a given point,

be very careful with your signs.

Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.

So to find the coordinates for this point, we start at the origin.

Then we move to the left 2 and down 1 so that's (-2, -1).

So the solution to this system is (-2, -1).

Answer:

E. 57 feet

Step-by-step explanation:

If you draw a rectangle and label the long side 5+2x, and the short side x, then that represents the rectangular floor.

The 2x is "twice the width".

The 5 added to the 2x is "5 feet longer than"

The x is the width of the room.

If the equation for the whole perimeter is 2(5+2x)+2x=166 <-(The perimeter)

                                     (Both of the long sides)^       ^(Both of the short sides)

Then we need to solve for x.

[tex]2(5+2x)+2x=166\\10+4x+2x=166\\10+6x=166\\6x=156\\x=26[/tex]

Next, we input the value we got into the equation 5+2x (The length of one side) and solve

[tex]5+2x\\5+2(26)\\5+52\\57[/tex]

So the length of the room is 57 feet.

Hope this helps!

The mean absolute deviation of the data is 30.

Given data:

To find the mean absolute deviation (MAD) of the given data, we need to follow these steps:

Calculate the mean (average) of the data set.

Find the absolute difference between each data point and the mean.

Calculate the mean of these absolute differences.

Given data set: 60, 105, 80, 125, 140, 95, 65, 170

Step 1:

Calculate the mean

Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) / 8

Mean = 840 / 8

Mean = 105

Step 2:

Find the absolute difference between each data point and the mean

|60 - 105| = 45

|105 - 105| = 0

|80 - 105| = 25

|125 - 105| = 20

|140 - 105| = 35

|95 - 105| = 10

|65 - 105| = 40

|170 - 105| = 65

Step 3:

Calculate the mean of the absolute differences

MAD = (45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8

MAD = 240 / 8

MAD = 30

The mean absolute deviation of the given data set is 30.

Interpretation:

The mean absolute deviation represents the average amount by which each data point deviates from the mean. In this case, the MAD of 30 indicates that, on average, the data points in the set deviate from the mean by approximately 30 units.

The two numbers are approximately 24.25 and 24.75.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

Let's call the two numbers x and y.

According to the problem, we have two equations:

x + y = 49 (since their sum is 49)

x - y = 1/2 (since their difference is 1/2)

We can solve this system of equations using the method of substitution.

First, we can rearrange the second equation to solve for one of the variables in terms of the other:

x - y = 1/2

x = y + 1/2

Now we can substitute this expression for x into the first equation:

(y + 1/2) + y = 49

2y + 1/2 = 49

2y = 48.5

y = 24.25

Now we can use this value of y to solve for x:

x = y + 1/2 = 24.25 + 1/2 = 24.75

Therefore, the two numbers are approximately 24.25 and 24.75.

Answer:

number of games played is 5

number of rides road 8

Step-by-step explanation:

8 x 2.25=18

5 x 1.25=6..25

18 + 6.25=24.25

The number of games Sydney played is 5 and the number of rides Sydney went on is 8.

Linear equation is the type of equation with highest power 1.

Assume the number games Sydney played be x. So, the number of rides she went is x+3.

The cost of 1 game is $1.25. So, the cost of x games will be 1.25x.

The cost of 1 ride is $2.25. So, the cost of x+3 rides will be 2.25(x+3).

The total cost is $24.25. Formulate the linear equation and solve it.

1.25x+2.25(x+3)=24.25

1.25x+2.25x+6.75=24.25

3.5x=17.5

x=5

Substitute x=5 into x+3.

5+3=8

Thus, the number of games Sydney played is 5 and the number of rides Sydney went on is 8.

Answer:

a) radius = 6.9288 units

b) OP = 13.857 units

Step-by-step explanation:

a)

As PA is tangent to the circle, the angle OAP is 90°, and if the angle of the arc AR is 60°, the angle AOP is also 60°.

So we can find the angle APO with the sum of internal angles of the triangle AOP:

90 + 60 + APO = 180

APO = 30°

Now, we can find the radius AO using the tangent relation of the angle APO, where the opposite side is the radius AO and the adjacent side is AP:

tangent(30) = AO / AP

0.5774 = AO / 12

AO = 0.5774 * 12 = 6.9288 units

b)

To find the length of OP, we can use the Pythagoras' theorem in the triangle AOP:

OP^2 = AO^2 + AP^2

OP^2 = 6.9288^2 + 12^2 = 192.01

OP = 13.857 units
