What is the denominator when 5/6 is multiplied by 7/8
Answer:48
Step-by-step explanation:
this is because 5x7 equals 35 and 6x8 equals 48 and the answer is 35/48
Answer:
the denominator would be 48
Step-by-step explanation:
8*6=48 which is done by multiplying the 2 denominators but the total fraction would be 35/48
The area of the rectangle is 64.8 square centimeters. What is the perimeter of the rectangle? 10cm and 8cm
The perimeter of the given rectangle is 32.2 cm.
What is a perimeter?The perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.
Given that, The area of the rectangle is 64.8 square centimetres.
Area = l*w
l*w = 64.8
l = 64.8/w
Perimeter = 2(l+w)
= 2(64.8/w+w)
= 129.6/w +2w
We take the derivative of P and set it to 0,
dP = -129.6/w²+2
-129.6/w²+2 = 0
129.6/w² = 2
2w² = 129.6
w² = 64.8
w = 8.05
Now, we have,
l = 64.8/w
∴ l = 64.8/8.05 = 8.05
The perimeter = 2(l+w)
= 2(8.05+8.05)
= 2*16.10
= 32.2 cm
Hence, The perimeter of the given rectangle is 32.2 cm.

Lee drank 1 2/3 quarts water Monday. He drank 2/5 water Tuesday. How amny quarts did he drink today?
Answer:
Lee drank 31/15 qt. of water (2 1/15 qt. as a mixed number, or approximately 20.07 qt. as a decimal).
Step-by-step explanation:
To add and subtract fractions, a least common denominator needs to be found. But first, to make it easier, mixed numbers should be replaced with improper fractions. So, Lee drank 5/3 qt. of water.
Now to find the LCD (least common denominator), the denominators of each fraction should be multiplied by 1, then 2, then 3, etc until a product of one fraction is the same as that of another (as shown):
For 2/5, the denominator is 5, so 5*1 = 5, 5*2 = 10, 5*3 = 15...
For 5/3, the denominator is 3, so 3*1 = 3, 3*2 = 6, 3*3 = 9, 3*3 = 4, 3*5 = 15...
15 is the LCD, since both denominators can be multiplied by a whole number for a product of 15.
Now, each fraction is multiplied by 1, by multiplying each fractions numerators and denominators by the number found previously that causes the denominator to equal 15:
For 2/5, 5*3 = 15, so both 2 and 5 are multiplied by 3
2* 3 = 6, 5 * 3 = 15, so 2/5 = 6/15
For 5/3, 3*5 = 15, so both 5 and 3 are multiplied by 5
5* 5 = 25, 3 * 5 = 15, so 5/3 = 25/15
Now these fractions can easily be added or subtracted by performing these operations on their numerators. Sonia drank 6/15 qt. more than Lee, so she drank 6/15 + 25/15 qt. of water, or 31/15 qt.

P(B) =
(Simplify your answer. Type an integer or a decimal.)
9514 1404 393
Answer:
P(B) = 0.65
Step-by-step explanation:
The appropriate formula is ...
P(A or B) = P(A) +P(B) -P(A and B)
Then P(B) is ...
P(B) = P(A or B) +P(A and B) -P(A)
P(B) = 0.8 +0.15 -0.3
P(B) = 0.65

Answer:
70 (I think)
Step-by-step explanation:
1/3 is 3.33 (threes go on forever) but thats only for 1/5 of an hour, so you multiply 3.33 by 5 and get 16.66 (pretty sure the sixes also go on forever) and thats one full hour, so you multiply 16.66 by 4.20 (4 1/5 but in decimal form) and you get 70
