A right cone has radius 5 ft and slant height 9 ft. The radius and slant height are both multiplied by 1/2. Which of the following correctly describes the effect on the surface area?

Answer:

I will let you answer this after reading below

Step-by-step explanation:

a=area

[tex] a = \pi {r}^{2} [/tex]

[tex]r = d \div 2[/tex]

write a in terms of d

[tex] a = \frac{\pi {d}^{2}}{ 4}[/tex]

since it's a semicircle divide a by 2 and that's your answer

Answer:

cos ∅ = 15/17

Step-by-step explanation:

hypotenuse² = 15² +8² = 225 + 64 = 289

hypotenuse = √289 = 17

cos ∅ = 15/17 =

Answer:

They are the same

Step-by-step explanation:

We are to check if (-5 + -3 ) =( -5 - +3)​

First you must know that the product of a positive and a negative n=sign will result in a negative sign i.e. + * - = -

Applying this in question;

(-5 + -3 )

= -5 - 3

= -8

similarly

( -5 - +3)​

= -5 - 3

= -8

Since both values are the same hence, (-5 + -3 ) =( -5 - +3)​

Answer/Step-by-step explanation:

First create a range for the number line. Label the number line. Then plot the minimum, lower quartile, median, upper quartile, and maximum values in this order. Draw a box from the lower quartile to the upper quartile, the line in the middle will go at the median. Now draw the line from the minimum & maximum values to the box.

Answer: 5cm and 8cm

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 26 ...... i

l × w = 40 ...... ii

We can reduce equation i to l + w = 13.

l + w = 13 ....... i

l × w = 40 ....... ii

From i, l = 13 - w ...... iii

Put the value of l into equation ii

l × w = 40

(13 - w) × w = 40

13w - w² = 40

13w - w² - 40 = 0

w² - 13w + 40 = 0

w² -8w -5w +40 = 0

w(w - 8) -5(w - 8) = 0

(w - 5) = 0 and (w - 8) = 0

w = 0 +5 and w = 0 + 8

w = 5

l = 8

The dimensions are 5cm and 8cm

Answer: 2(12 × 8)

Step-by-step explanation:

The area of the rug will be gotten by multiplying the length by its width. This will be:

= 12 foot × 8 foot

= 96feet²

Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:

= 2(12 × 8)

= 2(96)

= 192feet²

Answer:

32

Step-by-step explanation:

To find the perimeter just add all of the sides together.

5+7+5+1+4+3+4+3=32

Answer:

2

Step-by-step explanation:

Since x=-2

-2+3y=4

Add 2 on both sides

3y=6

Divide 3 on both sides

y=2

Answer:

x is equal to -2

the equation is x + 3y = 4

so we substitute the value of 'x' which is -2 in equation x + 3 = 4

Step-by-step explanation:

then we move 3y on left side.

then we add 4 + 2 which is 6.

then it will be, y = 6/3

which is 2

therefore we get y = 2

a(n+y) = 10t + 32

n+ y = (10t + 32)/a

y = ((10t+32) /a) -n

Answer:

b = -5 and c = -4

Step-by-step explanation:

The common ratio here is r = 20/(-5), or -4, and the first term, a(1), is -5.  Thus, the explicit formula is

a(n) = a(1)*r^(n -1)    (must use parentheses, as shown)

and so we have a(n) = -5*(-4)^(n - 1).  b = -5 and c = -4

Answer:

slope is undefined

Step-by-step explanation:

If the line was horizontal it would be 0 but this is verticle

Answer:

Undefined

Step-by-step explanation:

There's really no equation to this as it is a vertical line.

if it was horizontal it would be 0

but since it is a vertical line you can't really calculate meaning the answer is just undefined.

Step-by-step explanation:

Answer:

The absolute value is the distance between the number and zero on a number line, while opposites are the same distance from the zero on the  number line, so they are also on opposite sides of 0.

Step-by-step explanation:

Answer:

151

Step-by-step explanation:

So you have to start by finding the total number of degrees inside the shape. The shape has 5 sides.

So using this formula:

(n-2) * 180

(5-2) * 180

= 540 degrees inside the shape

Then solve for x.

5x +2 + 10x - 3 + 8x -19 + 13x - 31 + 7x -11 = 540

43x -62 = 540

43x = 602

x = 14

Plug in for S.

13 (14) -31
