Answer: 224 feet
Step-by-step explanation:
Each curtain is 48 inches long, and she wants to make 56 curtains.
However, the fabric store sells by the foot.
There are two ways to do this:
1) You can convert beforehand.
48 inches= 4 feet because 1 inch=1/2 foot.
Multiply 48 by 1/12 to find how many feet are in 48 inches.
= 48/12
=4
So 48 inches= 4 feet
Now, each curtain is 4 feet. There are 56 curtains to be made.
Now multiply by 4 to find how many feet are in 56 curtains.
56x4=224 feet.
Answer= 224 ft
Or: You can convert afterwards
48x56= how many inches in 56 curtains
= 2,688 inches
Then, convert to feet!
1 inch= 1/12 foot
2688 multiplied by 1/12:
=2688/12
=224 feet
Answer= 224 feet
Either way, you both get 224 feet.
Answer:
B
Step-by-step explanation:
You need the equation to equal 0
4x²-5=3x+4 Subtract 4 and 3x from both sides
4x²-5-4-3x
4x²-3x-9
a=4 b=-3 c=-9
(-b±√(b²-4ac))/2a
(-(-3)±√-3²-4(4)(-9)) / (2(4)
Answer:
Step-by-step explanation:
Recall the definition for conditional probability.
We have P(A/D) = P(A and D)/P(D)
P(AD) = 2/17
P(A) = 8/17 and P(D) = 10/17
From the definition of conditional probability,
P(A/D) = P(AD)/P(D) = 2/17 divided by 10/17 = 1/5
But P(D/A) = P(AD)/P(A) = 2/17 divided by 8/17 = 1/4
Hence the two are not equal.
This is because there is a difference in the denominators
