I WILL MARK AS BRAINLIEST! Find the surface area and Volume of the following figures

Answers

Answer 1

Step-by-step explanation:

a) is really easy, right ?

the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.

there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1

SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²

the volume is just length×width×height

V = 7×2×1 = 14 in³

a little bit more difficult, but with a little trick just as easy.

the surface area consists of the 2 circle areas and the mantle "coating".

the area of a circle is pi×r².

we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.

the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.

now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.

circumference of a circle is 2×pi×r

so the surface area is 2×circle + (circumference circle)×12

SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =

≈ 534.07 ft²

the volume is one base area (circle) times height

V = pi×5²×12 = 300pi ≈ 942.48 ft³

Which of the following appears to be a scaled copy of the original image? *
YOU CAN CHOOSE MORE THAT ONE

Answers

Answer: Third Choice. B,C, and E

Concept:

A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.

Explanation:

Choice A. [tex]\boxed{FALSE}[/tex]

The figure given as choice A seems to be much thinner than the original image. Therefore, the figure did not copy each length in scale.

Choice B. [tex]\boxed{TRUE}[/tex]

The figure given as choice B seems to be the same size as the original image but different position. However, the position is not a concern in a scaled copy image. Therefore, the figure did copy each length in scale.

Choice C. [tex]\boxed{TRUE}[/tex]

The figure given as choice C seems to be larger than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Choice D. [tex]\boxed{FALSE}[/tex]

The figure given as choice D seems to be larger and wider than the original image. Therefore, the figure did not copy each length in scale.

Choice E. [tex]\boxed{TRUE}[/tex]

The figure given as choice E seems to be smaller than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Therefore, the choices would be B, C, E, which would be the third choice.

Extra: A shortcut (lazy) way to do the question

As listed above, A and D are clearly not to scale since one is much thinner, one is much wider. Therefore, we can directly neglect choices that contain A and D, which would only leave us with the third choice.

Hope this helps!! :)

Please help! Greatly appreciated sorry for really bad quality

Answers

The first answer.

Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units

The calculator isn't water or a fluid, therefore you have to follow the dimesions by the question. Since the Calculator is 14cm by 12.5cm, and the pencil case is 20cm by 10cm, the calculator cannot simply fit inside the pencil case as the calculator's width is longer than the pencil case's width.

What is the Leading Coefficient of 3x^6-2x^9+5x-12 when written in Standard Form?

Step-by-step explanation:

Given polynomial:

3x⁶ - 2x⁹ + 5x - 12

Convert this into standard form, order in descending powers:

-2x⁹ + 3x⁶ + 5x - 12

The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.

[tex]\\ \rm\longmapsto 3x^6-2x^9+5x-12[/tex]

What is the step by step explanation on how to solve 8 1/2 + 3 4/5? I already know the answer is 12.3 but I just need help on the how to do the work.

Answers

To do this, first add the whole numbers: 8 + 3 = 11. Set that aside for a moment.

To add the fractions, 1/2 + 4/5, you need a common denominator. With 2 and 5, you’d have an LCD of 10.

1/2 = 5/10

4/5 = 8/10

So 1/2 + 4/5 = 5/10 + 8/10 = 13/10

Now, 13 is bigger than 10, so 13/10 is the same as 1 and 3/10.

We’ll add that to the 11 we found back in the beginning and get 11 + 1 and 3/10 = 12 and 3/10 or 12.3.

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step

Answers

Answer:

-58, -57, -56

Step-by-step explanation:

if the first integer is x,

the second integer must be x + 1 (because it's consecutive)

and the third must be x + 2

Therefore:

3 times the sum of the first and third integers is -342:

3 * (x + (x+2) ) = -342

Combine like terms in parentheses

3 * (2x + 2) = -342

Distribute the 3 to the 2x and the 2:

6x + 6 = -342

Subtract 6 on both sides

6x = -348

Divide by 6 on both sides

x = -58

x + 1 = -57

x + 2 = -56

-58, -57, -56

Check:

3 * (-58 + -56) = 3 * -114 = -342

I hope this can help you

So basically the figure is just flipped over so it’s the same thing as the other side just placed in a different spot. So angle b would be 2.2. Angle a would be 3.2. Look at the other angle and do what I did for angle b and a and you would be able to figure it out.

which number produces an irrational number when added to 1/4

Answers

π is an irrational number when it is added to 0.4 we will get an irrational number

Answer:

A. 0.545454 - 1/4 = 0.295454 yes this is an irrational number

C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number

Step-by-step explanation:

A. 0.545454 - 1/4 = 0.295454 is an irrational number as the closest fraction is shown below at 3 decimal points only

As this can be converted to a fraction 147727 /500000 ≈ 0.295

B. - 4/9 - 1/4 = -0.694444444 is not an irrational number so answer is no

As this can be converted to a fraction -173611111 / 250000000

To write 0.694444444 as a fraction you have to write 0.694444444 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.694444444 = 0.694444444/1 = 6.94444444/10 = 69.4444444/100 = 694.444444/1000 = 6944.44444/10000 = 69444.4444/100000 = 694444.444/1000000 = 6944444.44/10000000 = 69444444.4/100000000 = 694444444/1000000000. Then divide by 470 and we know to use this some as 250000000/531915 = 470

C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number

closest fraction is only 4 significant figures

4017627 / 1250000

=3 and 267627 over 12500003

267627 /1250000

≈3.214 so in closer proof it is an irrational number.

D. sq rt 4 - 1/4 = 1.75 is not an irrational number as this fraction is 7/4 = 1 3/4
