Step-by-step explanation:

A rectangular tank 3600 bricks measuring 1/5m by 1/8m by 1/10m into the tank before the water overflows.

To find bricks can be put into the tank before the water overflows,  the volume of water in the tank and then determine the volume of each brick.

The volume of water in the tank  length, width, and depth:

Volume of water = length × width × depth = 3m × 2m × (3/4)m

The volume of each brick:

Volume of each brick = length × width × height = (1/5)m × (1/8)m × (1/10)m

Divide the volume of water in the tank by the volume of each brick:

Number of bricks = (Volume of water) / (Volume of each brick)

Now let's substitute the given values into the formulas and

Volume of water = 3m × 2m × (3/4)m = 9/2 m³

Volume of each brick = (1/5)m × (1/8)m × (1/10)m = 1/400 m³

Number of bricks = (9/2 m³) / (1/400 m³)

= (9/2) / (1/400)

= (9/2) × (400/1)

= 9 × 400 / 2

= 3600

Step-by-step explanation:

We can call the number x. 75% can be expressed as 0.75 so we can write the following equation: 0.75x = 24. Dividing both sides by 0.75 to get rid of the coefficient of x, we get that x = 32.

Answer:

32.

Step-by-step explanation:

Let's say the number we are trying to find is x.

24 = 0.75x

0.75x = 24

x = 24 / 0.75

x = 32

The Area of triangle with the given height 10 cm and base 6 cm is calculated to be  30 square centimeters.

To calculate the area of a triangle with height 10 cm and base 6 cm, we can use the formula:

Area = (1/2) x Base x Height

Substituting the given values, we get:

Area = (1/2) x 6 cm x 10 cm

Area = 30 square cm

Therefore, the area of the triangle is 30 square centimeters.

We can see that the area of the triangle is calculated by multiplying the base and height and then dividing the result by 2. In this case, the height of the triangle is 10 cm and the base is 6 cm, so the area is 30 square cm. This formula can be used to calculate the area of any triangle, regardless of its size or shape.

Answer:

bottom right rectangle: 5x − y

bottom circle: 6x

Step-by-step explanation:

First, solve for the bottom right rectangle by finding the difference between the top right rectangle and the middle right circle:

(9x + 4y) − (4x + 5y)

= (9x − 4x) + (4y − 5y)

= 5x − y

Next, to find the bottom circle, add the bottom left rectangle with the bottom right rectangle (the one we just solved for):

(x + y) + (5x − y)

= (x + 5x) + (y − y)

= 6x

For the given similar polygons, the value of x equal to 30.

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   \(\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\)

Then,

                                    \(\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}\)

The length of the ribbon to the nearest tenth is 50.3 inches.

To find the length of the ribbon that surrounds the edge of a circular hat that has a radius of 8 inches, we can use the formula for the circumference of a circle.

The formula for the circumference of a circle is given by the following:

C = 2πr

Where C represents the circumference of the circle, π represents the constant value of pi which is approximately equal to 3.14, and r represents the radius of the circle.

Given that the circular hat has a radius of 8 inches, we can use this value to find the circumference of the circle.

Hence, we have: r = 8 inches

C = 2πr

C = 2π(8)C = 16π

The length of the ribbon that surrounds the edge of the circular hat is equal to the circumference of the circle. Therefore, the length of the ribbon is:16π ≈ 50.3 inches (to the nearest tenth)

Therefore, the length of the ribbon to the nearest tenth is 50.3 inches.

AB and DC are parallel to each other, so they are the same length. Set their lengths equal to each other and solve for x

4x = 7x - 9

4x - 7x = 7x - 7x -9

-3x = -9

-3x/-3 = -9/-3

x = 3

Now solve for AB.

AB = 4x

AB = 4(3)

AB = 12

The expressions for (f+g)(x)=5x-1, (f⋅g)(x)=6x²-3x and the value of (f-g)(4) is -5.

The given functions are f(x)=2x-1 and g(x)=3x.

Here,

(f+g)(x)= f(x)+g(x)

= 2x-1+3x

= 5x-1

(f·g)(x)=f(x)×g(x)

= (2x-1)×3x

= 2x×3x-1×3x

= 6x²-3x

(f-g)(4)

Here, (f-g)(4)=f(4)-g(4)

= 2×4-1-3×4

Step-by-step explanation:

First, find the amount of time she works every day.

Between 8:45 and 5:15, there are 8.5 hours.

Subtract 1 for her lunch break, so there are 7.5 hours worked every day

Then, calculate how much she gets every day:

7.5(8.75)

= $65.625

Multiply this by 5 to find her pay for the week:

65.625(5)

= $328.13 is her total pay for the week

The total pay for the week will be $318.75.

Therefore, the interquartile range of the company scores for the reference population is approximately 26.96.

To find the interquartile range (IQR) of the intelligence scores for the reference population, we need to calculate the difference between the third quartile (Q3) and the first quartile (Q1).

Since the scores are normally distributed with a mean of 120 and a standard deviation of 20, we can use the properties of the normal distribution to determine the quartiles.

The first quartile, Q1, corresponds to the 25th percentile, which is located at z = -0.674. We can calculate the value of Q1 as:

Q1 = mean + z * standard deviation = 120 + (-0.674) * 20 = 120 - 13.48 = 106.52

Similarly, the third quartile, Q3, corresponds to the 75th percentile, which is located at z = 0.674. We can calculate the value of Q3 as:

Q3 = mean + z * standard deviation = 120 + (0.674) * 20 = 120 + 13.48 = 133.48

Finally, we can calculate the interquartile range (IQR) as the difference between Q3 and Q1:

IQR = Q3 - Q1 = 133.48 - 106.52 = 26.96

Answer:

Step-by-step explanation:

In this scenario, the probability of success, p is 28% = 28/100 = 0.28

Number of samples, n = 160

Probability of failure, q = 1 - p = 1 - 0.28 = 0.72

Mean,µ = np = 0.28 × 160 = 44.8

Standard deviation, σ = √npq = √160 × 0.28 × 0.72 = 5.68

Let x be the random variable representing the number of wood samples from long-leaf pine trees with a fungal disease. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

the probability that you’ll have at least 50 diseased samples to return to your boss is expressed as

P(x ≥ 50) = 1 - P(x < 50)

For P(x < 50)

z = (50 - 44.8)/5.68 = 0.91

Looking at the normal distribution table, the probability corresponding to the z score is 0.819

Therefore,

P(x ≥ 50) = 1 - 0.819 = 0.181

Frequency of people who like DOGS = 55

Frequency of people who like HAMSTERS = 20

Frequency of people who like OTHERS = 25

Step-by-step explanation:

(As the dual bar chart is not given in the question, it is incomplete. The dual bar chart of this question is attached below)

No. of people who like CAT = 40

From the chart, we can see that the number of men and number of women who like CAT are equal.

Which means that out of 40 people, 20 men like CAT and 20 women like CAT.

Considering that 20 men like CAT, the bar chart of men who like CAT has a frequency 20. If we see the chart of men who like CAT, it takes 4 vertical steps to get to the frequency of 20, which means that 1 step represents 20/4= 5.

One vertical step has a frequency of 5

One vertical step has means a frequency of 5

Men who like DOGS = 5 steps = 5(5) = 25 Men

Women who like DOGS = 6 steps = 6(5) = 30 Women

Total people who like DOGS = 25 Men + 30 Women = 55 people

One vertical step has means a frequency of 5

Men who like HAMSTER = 3 steps = 3(5) = 15 Men

Women who like HAMSTER = 1 steps = 1(5) = 5 Women

Total people who like HAMSTER = 15 Men + 5 Women = 20 people

One vertical step has means a frequency of 5

Men who like OTHERS = 2 steps = 2(5) = 10 Men

Women who like OTHERS = 3 steps = 3(5) = 15 Women
