Lee drank 1 2/3 quarts water Monday. He drank 2/5 water Tuesday. How amny quarts did he drink today?

Answers

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.

The area of the rectangle is 64.8 square centimeters. What is the perimeter of the rectangle? 10cm and 8cm​

Answers

10cm + 10cm + 8cm + 8cm = 36cm

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.

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)
