Find the L.S.A and T.S.A and volume of prism. whose sides are 3, 4 and 5 and height is 20cm
The lateral surface area of prism is 240cm2, total surface area is 250cm2 of prism , the volume of prism is 100cm2.
What is lateral surface of prism?
The lateral surface area of the right triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h, where a, b and c are the bases of the rectangular faces and h is the common height or the total height of the prism. Also, (a + b + c) is the perimeter of the base (triangle).
What is total surface area of prism?
The total surface area of a right prism is T. S. A. = PH+2A, where P is the base perimeter, A is the base area, and H is the height of the prism.
What is volume of prism?
The formula for the volume of a prism is given by the product of the base and height of the prism. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism.
Given that,
The sides of prism are a=3cm, b= 4cm, c= 5cm
Also given that the height of the prism is h=20cm.
The lateral surface area of prism (LSA) = ah + bh + ch
Lateral surface area of prism = (3)(20)+(4)(20) +(5)(20)
Lateral surface area of prism = 60 + 80 + 100
Lateral surface area of prism = 240 cm2
The Total surface area of prism (TSA) = ph+2a
Total surface area = (LSA) + area of 2 bases
Total surface area = 240 + 2(5)
Total surface area = 250cm2
The volume of prism = base x height
Volume of prism = 5 x 20
Volume of prism = 100cm2.

greg is 5yr. older than randy, who is 3yr. older than Wilson. the sum of their ages is 32. how old is greg
The ages of Wilson, Randy and Greg given their total ages is 7, 10 and 15 years respectively.
This means that the total ages of Wilson, Randy and Greg is 7 years, 10 years and 15 years.
AlgebraLet's represent the information above as follows:
Wilson's age = xRandy's age = (x + 3)Greg = (x + 3) + 5Total ages = 32The total ages = Wilson + Randy + Greg
That is, Wilson's age, Randy's age and Greg's ages is given as:
32 = x + (x + 3) + (x + 3) + 5
32 = x + x + 3 + x + 3 + 5
32 = 3x + 11
32 - 11 = 3x
21 = 3x
x = 21/3
x = 7 years
Therefore, from the calculations above,
Wilson's age = x
= 7 years
Randy's age = (x + 3)
= 7 + 3
= 10 years
Greg = (x + 3) + 5
= (10) + 5

The solution to the system of equations is (2.5, -2)
How to determine the solution to the system of equations?The system of equations is given as:
2x + y = 3
2x - 5y = 15
Subtract the equations to eliminate the variable x
This is represented as
2x - 2x + y - -5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
y + 5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
6y = -12
Divide both sides of the above equation by 6
So, we have
y = -2
Substitute y = -2 in 2x + y = 3
2x - 2 = 3
This gives
2x = 5
Divide by 2
x = 2.5

According to the sliding filament model, which of these gets shorter during muscle contraction? (choose all that apply)
The required result of the sliding filament model given below.
What is the sliding filament model?The mechanism by which muscles contract is described by the sliding filament model. Actin and myosin myofilaments move over one another as a result of a cycle of repeated occurrences, constricting the sarcomere and creating tension in the muscle.
The A band is the middle, darkly pigmented area of the sarcomere that runs the entire length of the thick filaments. The portion of the thin filaments that cross over the thick filaments is also included. The I band is formed by the remaining thin filaments within the sarcomere but not by any thick filaments. Each A band has a narrow region in the middle called the H zone, which is made up entirely of dense filaments.
Myosin heads pull the thin filaments in the direction of the M line during muscle contraction. Because of this, the thin filaments glide inward, allowing their ends to overlap and connect at the sarcomere's core. The I band and H zone become smaller as a result.

A cylinder has a circular base.
3.3.2
As cylinders have circular bases, the formula for the area of the base of a cylinder should be the same as the formula for the area of a circle:
[tex]\boxed{\mathrm{Area = \pi r^2}}[/tex].
3.3.3
To find the volume of a cylinder, we can imagine stacking multiple circles on top of each other so that the height of the structure increases, and the shape becomes a cylinder.
This means that the volume of a cylinder is simply the area of the base circle multiplied by the height (h) of the cylinder.
∴ [tex]\boxed{\mathrm{Volume = \pi r^2h}}[/tex].

We can use the above formula to calculate the volume of the given cylinder, where:
• r = [tex]\mathrm{\frac{diameter}{2}}[/tex] = [tex]\frac{8}{2}[/tex] = 4 m
• h = 3 m
∴ [tex]\mathrm{Volume = \pi \times (4 \: m)^2 \times 3 \: m}[/tex]

How many zeroes are in the product of 40 × 10 7 ?
Answer:
Either, it's 2,800 and that would be 2 zeroes or it is 400,000,000 and that would be 8 zeroes
Step-by-step explanation:
40 x 10 x 7 = 2,800
40 x 10^6 = 400,000,000
Total 8 zeroes are in the product of 40 × 10⁷.
Let's step-by-step dissect the calculation and the total amount of zeros.
We are given the phrase 40 × 10⁷, where 10⁷ is defined as 10 multiplied by 7.
Step 1: Calculate 10⁷
10^7 means 10 raised to the power of 7, which is equal to 10,000,000 (10 million). This is because 10⁷ = 10 × 10 × 10 × 10 × 10 × 10 × 10 = 10,000,000.
Step 2: Calculate the product 40 × 10⁷
Now, we multiply 40 by 10,000,000:
40 × 10,000,000 = 400,000,000
The product 400,000,000 has a total of 9 digits.
Instead of just looking at the overall number of digits, we are more concerned with the amount of zeros in the product.
Counting the zeros:
In the number 400,000,000, there are 8 zeros. These zeros come from the seven factors of 10 in the product 10⁷.
So, the product of 40 × 10⁷ has 8 zeros.
In conclusion, the result of 40 times 10 raised to the power of 7 is 400,000,000, which has eight zeros. This is so because every factor of 10 adds a zero to the final total.
