Answer:

360"

Step-by-step explanation:

Firstly, you need to be able to convert your feet to inches. Remember, one foot is equal to twelve inches. You multiply six inches by five feet and later multiply by twelve to convert to inches.

I believe she can cut 360 6 inch strips from all of the rolls

Because:

the 5 rolls of ribbon each have six feet of ribbon on each roll, times the amount of inches in a foot

5(rolls of ribbon)*6(feet on each roll)*12(inches in a foot) = 360 (6 inch strips she can cut)

PLEASE give brainliest if correct!
have a nice day :-)

In a certain community, 36 percent of the families own a dog and 22 percent of the families that own a dog also own a cat. In ad

Answer: a) 0.0792 b) 0.264

Step-by-step explanation:

Let Event D = Families own a dog .

Event C = families own a cat .

Given : Probability that families own a dog : P(D)=0.36

Probability that families own a dog also own a cat : P(C|D)=0.22

Probability that families own a cat : P(C)= 0.30

a) Formula to find conditional probability :

$P(B|A)=\dfrac{P(A\cap B)}{P(A)}\\\\\Rightarrow P(A\cap B)=P(B|A)\times P(A)$ (1)

Similarly ,

$P(C\cap D)=P(C|D)\times P(D)\\\\=0.22\times0.36=0.0792$

Hence, the probability that a randomly selected family owns both a dog and a cat : 0.0792

b) Again, using (2)

$P(D|C)=\dfrac{P(C\cap D)}{P(C)}\\\\=\dfrac{0.0792}{0.30}=0.264$

Hence, the conditional probability that a randomly selected family owns a dog given that it owns a cat = 0.264

A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³.

iogann1982 [59]

Volume of a Cylinder (Drum) = πr²h

Substitute the known values,
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³

Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9

In short, Your Answer would be: $397.9

Hope this helps!

6. Write an equation of a line parallel to y = 3x + 9 and goes through the point (-1,5).

lisabon 2012 [21]

Answer: The equation parallel to the line is y=3x+8

Step-by-step explanation: Parallel lines have the same gradients, wr have a gradient for the above line which 3. The standard formula for the linear equation is y=mx+c

We have to calculate c since we have x and y.

y=mx+c

5= 3(-1)+c

c=8

The equation become y=3x+8
