Answer:

Value in $= 3x -600

Step-by-step explanation:

Let the value of the stock before investment= x

At the first year , the value tripled

Value after first year=3x

The second year , the stock reduces by $600.

So

The value of the stock after the second year

Value in $= 3x -600

Answer:

No

Step-by-step explanation:

2 liters = 2,000

80/3 = 26.6

the bottle leaks 26.6 milliliters in a min

26.6 * 60 = 1596

1596 / 1000 = 1.596 ( to convert to liters)

the bottle will leak 1.596 an hour

No, the bottle will not empty in one hour because the bottle will leak 1.596 an hour.

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

Volume of bottle = 2 liters = 2,000 ml

For three  minutes bottle leaks = 80 ml

In one minute bottle leak= 80/3

                                   = 26.6 ml

In one minutes the bottle leak

=26.6 * 60

= 1596 ml

=1.596 liters

1596 / 1000 = 1.596 ( to convert to liters)

No, the bottle will not empty in one hour because the bottle will leak 1.596 an hour.

Answer:

2x + 2 > 10

2x > 10 - 2

2x > 8

x > 8

B. x > 4.

Answer:

B. x>4

Step-by-step explanation:

2x + 2 > 10

In order to solve this inequality, we must isolate the variable, x , on one side of the inequality.

2 is being added to 2x. The inverse of addition is subtraction. Subtract 2 from both sides of the inequality.

2x+ (2-2) > 10-2

2x > 10-2

2x > 8

x is being multiplied by 2. The invers of multiplication is division. Divide both sides of the inequality by 2.

2x/2 > 8/2

x > 8/2

x > 4

The solution to the inequality 2x+2 > 10 is x > 4 and the correct answer is B.

Answer:

9/2π

=14.13716694

Step-by-step explanation:

The equation of the volume of the sphere:

V=4/3πr^3

If the diameter is 3cm, the radius is divided by 2, so 1.5cm.

Plug that in, 4/3π1.5^3

Use a calculator:

9/2π

=14.13716694

[tex]14,14~cm^{3}[/tex]

d = 3cm = 2r => r = d/2 = 3cm/2 = 1,5 cm

[tex]V=\frac{4}{3}\pi*r^{3}\\\\=\frac{4}{3}*\frac{22}{7}*3.375cm^{3}\\ \\=\frac{4*22*3.375}{21}cm^{3}\\ \\=\frac{297}{21}cm^{3}\\ \\[/tex]

Answer:

[tex]Area = 72in^2[/tex]

Step-by-step explanation:

Your question is incomplete without an attachment (See attachment)

Required

Determine the area of the shaded part

From the attachment;

Assume that the shaded portion is closed to the right;

Calculate  the Area:

[tex]Area_1 = Length * Width[/tex]

[tex]Area_2 = 8in * (6in + 6in)[/tex]

[tex]Area_2 = 8in * 12in[/tex]

[tex]Area_1 = 96in^2[/tex]

Next;

Calculate the Area of the imaginary triangle (on the right)

[tex]Area_2 = \frac{1}{2} * base * height[/tex]

[tex]Area_2 = \frac{1}{2} * (6in + 6in) * 4in[/tex]

[tex]Area_2 = \frac{1}{2} * 12in * 4in[/tex]

[tex]Area_2 = \frac{1}{2} * 48in^2[/tex]

[tex]Area_2 = 24in^2[/tex]

Lastly, calculate the Area of the Shaded Part

[tex]Area = Area_1 - Area_2[/tex]

[tex]Area = 96in^2 - 24in^2[/tex]

[tex]Area = 72in^2[/tex]

Hence,

The area of the shaded part is 72in²

Answer:

The correct answer is:

A) Average income per household

Step-by-step explanation:

Correlation of variables is the statistical relationship between two variables. A correlation is positive if both variables move in the same direction (e.g both are increasing, or both are decreasing), and negative if the variables move in different directions - as one variable increases, the other decreases.

Correlation does not imply causation: This means that one can not legitimately associate a cause-and-effect relationship between the two variables, especially when there is a third variable (lurking) that has an effect on the outcomes that is not included as an explanatory or response variable.

In this example, it cannot be legitimately shown that increasing the number of cars per household would cause members of the community members to purchase health insurance, but when we bring in the lurking variable, which is the increase in average income per household, we can see that this possibility might cause more people to buy more health insurance even after they have purchased cars, because they have more money to spend.

Answer:

BC=6

Step-by-step explanation:

The perimeter is the sum of all the side lengths.

Thus, add up all the sides.

And we already know the perimeter is 64. Thus:

[tex](3z)+(10)+(z-1)+(2z+3)+(10)=64[/tex]

Combine like terms and add the numbers:

[tex]6z+22=64[/tex]

Subtract 22 from both sides:

[tex]6z=42[/tex]

Divide by 6:

[tex]z=7[/tex]

So, z is 7.

BC is z-1. Therefore:

[tex]BC=z-1\\BC=7-1=6[/tex]

So, BC is 6.

Answer:

  ∠DAB = 80°

  ∠BAC = 105°

Step-by-step explanation:

You are given ...

  ∠DAC = 25° = (x -20)°

Adding 20°, we have ...

  x° = 45°

Then the measures of the other angles are ...

  ∠DAB = (2x -10)° = 2(45°) -10°

  ∠DAB = 80°

and

  ∠BAC = ∠DAB +∠DAC = 80° +25°

  ∠BAC = 105°

Answer:

97

Step-by-step explanation:

Given the following conditions :

board measuring 1x100, each square is numbered from 1 to 100

Three colors are used to paint the squares from left to right in the sequence :

one blue, two reds and three green squares in a repeated pattern.

What is the highest numbered square that is painted blue?

The sequence of painting is repeated after :

(1 + 2 + 3) = 6 successive squares

Since the number of squares = 100

Maximum complete repetition possible :

100 / 6 = 16 remainder 4

Hence 16 * 6 = 96 (the highest complete sequence terminates on the square numbered 96)

On the 97th square, another sequence begins which is a blue and the 100th square is painted the first of the 3 green colors.

Hence, the highest numbered square that is painted blue is 97

Patterns are simply the rules that guide the formation of elements in a dataset. The highest numbered square that is painted blue is 97.

The sequence is given as:

[tex]Blue = 1[/tex]

[tex]Red = 2[/tex]

[tex]Green = 3[/tex]

The number of squares is given as:

[tex]n = 100[/tex]

First, we calculate the number of complete iteration of the sequence of squares.

[tex]Total = Blue + Red + Green[/tex]

[tex]Total = 1+2+3 =6[/tex]

So, the complete iteration (k) is:

[tex]k = \frac{n}{Total}[/tex]

[tex]k = \frac{100}{6}[/tex]

[tex]k = 16.67[/tex]

Remove decimal (do not approximate)

[tex]k = 16[/tex]

Next, calculate the position of the last element in the iteration.

[tex]Position = k \times Total[/tex]

[tex]Position = 16 \times 6[/tex]

[tex]Position = 96[/tex]

The blue square is the first on each iteration.

So, the highest numbered blue square is:

[tex]Highest = Position + Blue[/tex]

[tex]Highest = 96 + 1[/tex]

[tex]Highest = 97[/tex]

Hence, the highest numbered square that is painted blue is 97.

Answer:

12. 50 degrres

13. 90 degrees

14. 40 degrees

15. 50 degrees

16. 130 degrees

17. 90 degrees

Step-by-step explanation:

12. Angle UAY is equal to 50 degrees as it is stated in the graph

13. Angle YAZ is 90 degrees, as there is a square at the angle, meaning that the angle is a right angle.

14. Angle ZAX + Angle UAY + Angle YAZ = 180, as it is supplementary.

We know Angle UAY and Angle YAZ, so we can find Angle ZAX

Angle ZAX = 180 - UAY - YAZ = 180 - 50 - 90 = 40 degrees

15. Angle XAW = 50 degrees, as it is vertical angles with Angle UAY.

16. Angle WAU = Angle YAX = Angle YAZ + Angle ZAX = 90 + 40 = 130 degrees

17. Angle ZAW and Angle YAZ are supplementary, so they add up to 180 degrees.

Angle YAZ = 90 degrees, so Angle ZAW must also equal 90 degrees.

Answer:

137

Step-by-step explanation:

Given the following :

Margin of Error (E) = 7% = 0.07

Confidence level = 90% = 0.9

Prior study (p) = 54% = 0.54

Using the sample size formula:

([Z/E]^2) × p × (1 - p)

(1 - p) = 1 - 0.54 = 0.46

Z score at 90% confidence interval. = 1.645

[(1.645 / 0.07)^2] * 0.54 * 0.46

(23.5^2) * 0.54 * 0.46

552.25 * 0.54 * 0.46

= 137.1789

= 137

Sample size = 137
