When chad had one cat he needed to serve 1/5 of a can of cat food each day. Now that chad adopted a second cat he needs to serve

Akimi4 [234]

Answer:

$5\frac{3}{10}$ cans extra food is needed to feed the second cat.

Step-by-step explanation:

Given:

When chad had one cat he needed to serve 1/5 of a can of cat food each day. Now that chad adopted a second cat he needs to serve a total of 11/2 cans each day.

Now, to find the extra food is needed to feed the second cat.

Food needed for one cat = $\frac{1}{5}\ of\ can.$

Food needed for both one and second cat needed = $\frac{11}{2}\ =5\frac{1}{2}\ cans.$

Now, extra food needed to feed the second cat:

Food needed for both one and second cat needed - food needed for one cat.

$\frac{11}{2} -\frac{1}{5}\\\\=\frac{55-2}{10} \\\\=\frac{53}{10}$

$=5\frac{3}{10}\ cans.$

Therefore, $5\frac{3}{10}\ cans$ extra food is needed to feed the second cat.

Answer:

Step-by-step explanation:

Remember:

$\boxed{(1+y)^{\frac{1}{2} }= 1+\dfrac{y}{2} -\dfrac{y^2}{2*4} +\dfrac{1*3*y^3}{2*4*6} +K\ with -1 < y \leq 1 }\\\\\\Let\ say\ 4-x=1+y\ or\ y=3-x\\\\\\(4-x)^{\frac{1}{2} }=1+\dfrac{3-x}{2} -\dfrac{(3-x)^2}{2*4} +K\ with\ 2\leq x$

Ava used the following equation in order to solve a math problem involving integers.

AnnZ [28]

Answer:

The only equation which is incorrect is in option B.

Step-by-step explanation:

Eva used the following equation in order to solving integers, which is

$\frac{-h}{-k} = j$

⇒ $j = \frac{h}{k}$ ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that $- j = \frac{- h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

In option B) it is given that $- j = \frac{- h}{- k}$

⇒ $j = - \frac{h}{k}$ which is not same as equation (1).

In option C) it is given that $- j = \frac{h}{- k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Again, in option D) it is given that $j = \frac{h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)

Tony needs 16 inch-long pieces of gold chain to

Vitek1552 [10]

Answer:

Option (1). 6 inches

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces ?

Tony has a piece of chain = 4.5 feet long

≈ 4.5 × 12 inches

≈ 54 inches

Number of necklaces Tony wants to make = 3

Length of every piece of gold chain required for one necklace = 16 inches

Total length of gold chain required for 3 necklaces = 3 × 16 inches

= 48 inches

Length of remaining chain = 54 - 48 = 6 inches

Therefore, Option (1) will be the answer.
