how do you find surface area with a detail explanation.
giving briniest.

Answers

Answer 1

Surface area is the total area on the surface of a three-dimensional shape. The main formula you can use is SA = 2lw + 2lh + 2hw. This means that you would first multiply the length by the width and multiply that product by 2, multiply the length and the height and multiply that product by 2, and lastly multiple the width and the height and multiply that product by 2. After you multiply what you need to multiply, you add all of your products together, thus resulting in the surface area of the figure.

Answer 2

The formula for surface area depends on the shape
Here are some common ones
Cuboid: 2(lb+bh+hl)
Cube:6l^s
Cylinder:2 x 22/7 x r(r+h)

1st perimeter would be 8+8+2+2 which is 20 and the second is 5*4 which is also 20. so ig the answer for that would be neither one is longer cuz they are the same length.

in the next question you have to find the perimeter from the area. the area is length times width and the shape is a square. Therefore, just figure out what number squared is equal to 64m^2, which would be 8m. You then multiply 8m by 4 which gets you 32m. 32m is the perimeter of the square.

the shape on the very right is just 5*6, so the area of that is 30. the other shape, to find the sides, just do (6+6)(10-5) which simplifies to 12*5. 12*5= 60 and when you add 30 to that you get the final area of the figure, 90cm.

B) y = 5x
C) y = 6x
D) y = 1/5x

Answers

The solution is, choice B) [tex]y=5x[/tex] represent a proportional relationship.

What is proportional relationship?

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y\div x = k[/tex] or [tex]y = kx[/tex]

here, we have,

we know that,

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so, we get,

choice A) [tex]y=30x[/tex]

Is a linear equation that passes through the origin

therefore,

The case A) represent a proportional relationship

choice B) [tex]y=5x[/tex]

Is a linear equation that passes through the origin

therefore

The case B) represent a proportional relationship

choice C) [tex]y =6x[/tex]

Is a linear equation but not passes through the origin

therefore

The case C) does not represent a proportional relationship

choice D) [tex]y = \dfrac{1}{5}x[/tex]

Is a linear equation but not passes through the origin

therefore

The choice D) does not represent a proportional relationship

Hence, The solution is, choice B) [tex]y=5x[/tex] represent a proportional relationship.

In the given triangle, the measure of angle C is 32°

Calculating the measure of angles

From the question, we are to determine the value of angle C.

Let half of ∠IAB = a

and half of ∠IBA = b

Then,

a + b + 106° = 180° (Sum of angles in a triangle)

a + b = 74°

Also,

2a + 2b + ∠C = 180° (Sum of angles in a triangle)

2(a + b) + ∠C = 180°

2(74°) + ∠C = 180°

148° + ∠C = 180°

Subtract 148° from both sides

148° - 148° + ∠C = 180° - 148°

∠C = 32°

Hence, the measure of C is 32°

There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.

1
4
8
32

Answers

Answer:

There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.

When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.

The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):

Expected number of blue marbles = (1/4) * 4 = 1

Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.

1) 1

Reasoning:

There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.

Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.

The cost that will maximize the demand, considering the quadratic function, is given as follows:

$3.

How to maximize the demand?

The quadratic function representing the demand is given as follows:

y = -10x² + 60x + 180.

The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:

x = -b / (2a)

The coefficients of the quadratic function in this problem are given as follows:

a = -10, b = 60.

The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:

x = -60/(2 x (-20))

x = 3.

Hi,would you please help me to solve this math problem?
How would the length of a circle change if:
a) the radius is increased 2 times
b) the radius is decreased 3 times
c) the diameter is increased 6 times?

Answers

Answer:

a) If the radius of a circle is increased 2 times, the length of the circle (circumference) will increase by a factor of 2π or approximately 6.28 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is doubled, then the circumference will also be doubled.

b) If the radius of a circle is decreased 3 times, the length of the circle (circumference) will decrease by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is divided by 3, then the circumference will also be divided by 3 and multiplied by 2π.

c) If the diameter of a circle is increased 6 times, the length of the circle (circumference) will increase by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = πd, where d is the diameter. If the diameter is multiplied by 6, then the circumference will also be multiplied by 6π

Step-by-step explanation:

pls Mark me As a brainlist

a) length of the circle increased by 2 times.

b) length of the circle decreased by 3 times.

c) length of the circle increased by 6 times.

Length of a circle that is the circumference of the circle is given by the formula = 2πr ( let's say C)

a) Given that the radius of the circle is increased by two times.

R = 2r

Required length of the circle = 2πR = 2π(2r) = 2×2πr = 2C

Hence, the length of the circle will be increased by 2 times.

b) Given that the radius is decreased by 3 times.

R= r/3

Required length of the circle = 2πR = 2π(r/3) = (2πr)/3 = C/3

Hence, the length of circle will be decreased by 3 times.

c) Given that the diameter of the circle is increased by 6 times.

D = 6d = 6×2r = 12r

Required length of the circle = πD= π×12r = 6(2πr) = 6C

Hence, the required length of circle will be increased by 6 times.
