Answer:

19 skins

Step-by-step explanation:

Total surface area of the cone = πr(r+l)

r is the radius = 10ft/2 = 5ft

l is the slant height

l^2 = 12^2 + 5^2

l^2 = 144+25

l^2 = 169

l = 13ft

Get the surface area

TSA = 3.14(5)(5+13)

TSA = 15.7*18

TSA = 282.6 ft^2

If each skin covers 15 sq. feet

Number of skin needed = 282.6 /15

Number of skin needed = 18.84

Number of skin needed is approximately 19 skins

Answer: \bold{y=\dfrac{24}{x}} ; indirect variation ; x = 2.4

<u>Step-by-step explanation:</u>

direct variation is when: \dfrac{y}{x}=k   ; where k is the constant rate

indirect variation is when: xy = k  ; where k is the constant rate

In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation: y = \dfrac{24}{x}

since k = 24, then input y = 10 and k = 24 into the equation above:

10 = \dfrac{24}{x}

10x = 24

x = \dfrac{24}{10}

x = 2.4

Two-thirds of a number added to itself is 20. What is the number?
vivado [14]

Answer:

12

Step-by-step explanation:

2/3 x + x = 20

2/3 x + 3/3x = 20

5/3 x = 20   ... times 3/5 both sides

x = 12

check: 2/3 x 12 + 12 = 8 + 12 = 20

Can someone please help me with the question, a/4 = 15/12 a=?
malfutka [58]

Answer:

a = 5

Step-by-step explanation:

a/4 = 15/12

We can use cross products to solve

a* 12 = 4*15

12a = 60

Divide each side by 12

12a/12 = 60/12

a =5

Is 10/18 in decimal form a terminates or repeating decimal
Oksana_A [137]

Hey there! I'm happy to help!

To write a fraction as a decimal, you simply divide the numerator by the denominator.

10÷18=0.55555.... (the 5s never end!)

We see that the 5s repeat forever. This means that this is a repeating decimal.

Have a wonderful day! :D
