2. Find the surface area of the regular pyramid shown to the nearest whole
number.

Answers

Answer 1

Answer:

208m^2

Step-by-step explanation:

area of hexagon = 93.53 using its equation

area of single triangle = 0.5(6*6)

area of all triangles = 6(0.5(6*6))

total area = 207.53

NWN = 208

In a concert band, the probability that a member is in the brass section is
0.50. The probability that a member plays trombone, given that he or she is in
the brass section, is 0.24.
What is the probability that a randomly selected band member is in the brass
section and plays trombone?
• A. 0.74
•
B. 0.12
• C. 0.26
• D. 0.48

Answers

Answer:

the answer is C. 0.26

Step-by-step explanation:

Because 0.50 + 0.24 is 0.74 and I'm guessing it goes to 1.0

So you subtract 1.0 from 0.74 to get 0.26

4. If you are moving a 25 N weight, over a distance of 2.5 meters, how much work is being
done?

Answers

Answer:

62.5 J

Step-by-step explanation:

Formula

Work = Force x Distance (Displacement)

Given :

Force = 25 NDistance = 2.5 m

Solving

Work = 25 x 2.5Work = 62.5 J

The work done with the given force and distance is 62.5 Newton meter.

What is time and work?

The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the Time taken when the amount of work done is constant.

Given that, force = 25 N weight and distance = 2.5 meters

We know that, work = Force×Distance

Here, work = 25×2.5

= 62.5 Newton meter

Therefore, the work done is 62.5 Newton meter.

Expand and simplify 2(x+7)+3(x+1)

Answers

To solve this function, we must add like terms until there is nothing that we can add, multiply, subtract, divide, or simplify

[tex]2(x+7) +3(x+1) = 2x + 14 + 3x + 3 = 5x + 17[/tex]

Hope that helps!

To solve this function the two most important things are The distributive property and combining like terms.

Steps:
1. Distribute the numbers on the outside of the parentheses to one’s on the inside
2. Then combine the like terms. Such as 3x and 4x.
3.Simplify if needed.
In this case after combining like terms it is the simplest this equation will get because you can’t combine 5x with 17. They aren’t like terms.

2(x +7)+3(x +1)
= 2x+14+3x+3
= 5x+17

Hope this helps! :)

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 22 feet up. The ladder makes an angle of 77^{\circ}

with the ground. Find the length of the ladder. Round your answer to the nearest tenth of a foot if necessary.

Answers

The ladder and the outside wall form a right triangle

The length of the ladder is 97.8 feet

How to determine the length of the ladder?

The given parameters are:

Distance (B) = 22 feet

Angle of elevation (θ) = 77 degrees

The length (L) of the ladder is calculated using the following cosine ratio

cos(θ) = B/L

So, we have:

cos(77) = 22/L

Make L the subject

L = 22/cos(77)

Evaluate the product

L = 97.8

Hence, the length of the ladder is 97.8 feet

The volume and surface area of the composite shape are 575.6cm³ and 518.1cm² respectively

How to calculate the volume and surface area of composite shapes

Composite shapes are the combination of two or more shapes combined together.

The composite shape given is made up of a hemisphere and a cone

Volume of the composite shape = 2/3πr³ + 1/3πr²h
Volume of the composite shape = 1/3πr²(2r+h)

Volume of the composite shape = 1/3(3.14)(5)²(2(5)+12)

Volume of the composite shape = 1/3(3.14)(5)²(22)
Volume of the composite shape = 575.6cm³

Hence the volume of the composite shape is 575.6cm³

Calculate the surface area

Surface area = πr(r+l) + 3π r²

Surface area = 3.14(5)(13+5) + 3(3.14)(25)
Surface area = 282.6 + 235.5 = 518.1 square cm

Hence the surface area of the composite figure is 518.1 square cm

Isabella is calculating the interest earned on a deposit of $3,000 in an account that earns 4% compound interest after 6 years.

Answers

given:

$3,000 in an account that earns 4% compound interest after 6 years.

solution:

[tex]p = 3000[/tex]

[tex]r = 4[/tex]

[tex]t = 6years[/tex]

[tex]interest = \frac{prt}{100} [/tex]

[tex] = \frac{3000 \times 6 \times 4}{100} [/tex]

[tex] = 720[/tex]

therefore, $720 is the current amount of interest.

The cost of attending an amusement park is $15 for children and $35 for adults on a particular day the attendance at the amusement park is 25,000 attendees and the total money earned by the park is 600,000 use a given matrix equation to solve for the number of children tickets sold

Answers

The total number of children tickets sold on the particular day is; 13750.

What is the total number of children tickets sold?

It follows from the task content that;

x + y = 25,000

15x + 35y = 600,000

On this note, it follows that the total number of children and adult tickets sold on that particular day is; x and y respectively.

Upon solving the equation simultaneously, x=13750.

Hence, the total number of children tickets sold is; 13750.

https://brainly.com/question/16863577

Answer:

13,750

Step-by-step explanation:

Switch values a and d value a 1 and value d 35 and then after that make values b and c negative so turn value b 1 into -1 and turn value c 15 into -15 and then follow this method a×d-(-b)×(-c) so like this 1×35-(15)(1)= 35-15=20 and thats the determinant so then you do put it on a fraction below 1 so like this 1/20 times the top part of the matrix (35 -1 ) and the bottom part of the matrix (-15 1) so mulitply every value by 0.05 so we end up with the top part of the matrix (1.75 -0.05)

and the bottom part of the matrix (-0.75 0.05) and then we multiply them like this

1.75(25,000) + (-0.05)(600,000)= 43,750 - 30,000= 13,750

-0.75(25,000) + 0.05(600,000) = -18,750 + 30,000= 11,250

so the missing matrix is

(13,750 11,250)

so the number of childrens tickets sold is 13,750
