The required volume of composite figure is 3465 cubic units. Option d is correct.

For composite figure made of triangular pyramid over triangular prism both as congruent base with dimension h = 10 and base =22.
Hight for both pyramid and prism is 19.5 and 25
Volume of composite figure is to be determine,  

When two or more solid put together to form new solid is said to be composite figure.

Here,
Volume of a pyramid = 1/3(1/2 base x height of triangle base)*h of
Volume of a pyramid = 1/3*22*10/2*19.5 = 715 cubic units

Similarly, for triangular prism
Volume of a triangular prism= 22*10/2x 25 = 2750 cubic units

Total volume =  volume of a triangular (pyramid +  prism)
Total volume = 715+2750
Total volume = 3465 cubic units.

Thus the required volume of composite figure is 3465 cubic units.

Answer:

c

Step-by-step explanation:

The correct option is Option B: is an A.P., because d = 10

An arithmetic progression, also known as an arithmetic sequence, is a sequence of numbers in which the difference between consecutive terms is constant. This constant difference is called the common difference and is denoted by 'd'.

The given sequence is:

-5, 5, 15, 25, ....

In every Arithmetic Progression (A.P.)

The common difference d

d= 2nd term - 1st term = 3rd term - 2nd term

d = 5-(-5) = 15 - 5

d = 10

Hence the common difference is 10,

Therefore  the sequence is an A.P., because d = 10

Step-by-step explanation:

Calculate the value of z and its probability, since with this we can know how likely it is that this will happen.

We have that the mean (m) is equal to 8.3, the standard deviation (sd) 1.2 and the sample size (n) = 15

They ask us for P (x =7.2)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (7.2 - 8.3) / (1.2 / (15 ^ (1/2))

z = -3.55

With the normal distribution table (attached), we have that at that value the approximate probability is:

P (z = -3.55) = 0.0001

The probability is 0.01 %

This affirms that the students do not sleep what the study says because the probability of this happening according to the survey is almost nil.

The third choice

Answer:

The distance in miles between  the towns is 67.5.

Step-by-step explanation:

Given:

On a map the scale is shown as 0.5 inches equaling 15 miles.

If the distance are 2.25 inches apart on the map between the towns .

Now, to find the distance in miles between  the towns.

The distance on the map between the towns = 2.25 inches.

Let the actual distance between the two towns be [tex]x.[/tex]

The scale of the map is 0.5 inches equaling 15 miles.

If, 0.5 is equivalent to 15 miles.

Thus, 2.25 is equivalent to [tex]x.[/tex]

Now, to solve using by cross multiplication method:

[tex]\frac{0.5}{15} =\frac{2.25}{x}[/tex]

By cross multiplying we get:

[tex]0.5x=33.75[/tex]

Dividing both sides by 0.5 we get:

[tex]x=67.5\ miles.[/tex]

The actual distance between the two towns = 67.5 miles.

Therefore, the distance in miles between  the towns is 67.5.

Answer:

437,500

Step-by-step explanation:

The percentage value of amount of money spent on radio advertising is given by R = $ 437,500

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage value of amount of money spent on radio advertising be represented as R

Now , the total amount of revenue money = $ 50,00,000

The percentage of money spent on traditional media = 25 %

So , the amount of money spent on traditional media = percentage of money spent on traditional media x total amount of revenue money

On simplifying , we get

The amount of money spent on traditional media = ( 25/100 ) x 5000000

The amount of money spent on traditional media = $ 12,50,000

Now , the percentage of amount spent on radio advertising = 35 %

So , the amount of money spent on radio advertising = ( 35/100 ) x amount of money spent on traditional media

On simplifying , we get

The amount of money spent on radio advertising = ( 35/100 ) x 12,50,000

The amount of money spent on radio advertising = $ 4,37,500

Hence , the amount of money on radio advertising is $ 4,37,500

Answer:

80 cm³

Step-by-step explanation:

Density = mass/volume

1.19 = 95.2/volume

Volume = 95.2/1.19

= 80

Answer:

80 cm cubed

Step-by-step explanation:

The density of a substance is denoted by d = m/V, where d is the density, m is the mass, and V is the volume.

Here, we know that the mass m = 95.2 grams and the density d = 1.19 g/cm cubed. So, plug these values into the formula:

1.19 = 95.2/V

Divide both sides by 1.19 and multiply both sides by V:

V = 95.2/1.19 = 80 cm cubed

Thus, the volume is 80 cm cubed.

Answer:

20cm

Step-by-step explanation:

7.2 + 7.2 + 2.8 + 2.8 = 20

Each side of the rectangle is equal to the side opposite from it. That means you have 2 sides of 7.2 cm and 2 sides of 2.8 cm.

To find perimeter, you add all the sides. So that's 7.2 + 7.2 + 2.8 + 2.8, which is 20 cm altogether.

Answer:

3x^2-10x-8

Step-by-step explanation:

Answer:

88.2 squared

Step-by-step explanation:

The formula to find the area of a circle is a = pi * r ^2

Let's replace the values that we know.

a = 3.14 x 5.3 ^2

First, we should do 5.3 ^2, which is 28.09.

a = 3.14 x 28.09

Now we are able to do 3.14 x 28.09 which is 88.2026

But that isn't it! We need to round to the nearest tenth, which is this digit:

88.2026

Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:

88.2

Final answer:

The area of the round mirror with a radius of 5.3 inches, when calculated using the formula A = πr^2 and rounded to the nearest tenth, is 88.2 square inches.

To find the area of the round mirror with a radius of 5.3 inches, we will use the formula for the area of a circle, which is A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle.

Given that the radius of the mirror is 5.3 inches, we can substitute this value into the formula to find the area:

A = π(5.3)^2 ≈ 88.2 square inches.

Let's plug in the radius:

When rounded to the nearest tenth, the area of the mirror is 88.2 square inches.

Answer:  The answer is 0.3

Step-by-step explanation:

Lily should expect to buy 1.5 boxes to get all four prizes.

This question belongs to the field of probability in Mathematics. The problem is asking how many boxes Lily should expect to buy in order to get all four prizes. This is a geometric problem because each box has a probability of 1/4 of containing a prize, and each trial is independent with the same probability of success. To solve this problem, we can use the concept of expected value.

The expected value is the average number of boxes Lily needs to buy to get all four prizes. The expected value can be calculated by multiplying the probability of each outcome by the number of boxes it takes to achieve that outcome, and then summing up these products:

Expected value = (1/4) * 1 + (1/4) * 2 + (1/4) * 3 + (1/4) * 4 = 1.5

Therefore, Lily should expect to buy approximately 1.5 boxes to get all four prizes.
