Whiskers the cat weighs 2 and 2 over 3 kg.piglio weighs 4 kg. How many times as heavy as piglio is whiskers
ruslelena [56]

Answer:

Whiskers is two-third times as heavy as piglio is.

Step-by-step explanation:

Given:

Weight of whiskers is, W=2\frac{2}{3}\ kg

Weight of piglio is, P=4\ kg

In order to compare their weights, we have to divide both the weights and then express one weight in terms of the other.

Therefore, dividing whiskers weight by piglio's weight, we get:

\frac{W}{P}=2\frac{2}{3}\div 4\\\frac{W}{P}=\frac{8}{3}\div \frac{4}{1}(\textrm{4 can be rewritten as 4/1 in fraction form})

Now, when we divide two fractions, we replace the division sign by multiplication and reverse the second fraction. This gives,

\frac{W}{P}=\frac{8}{3}\times \frac{1}{4}\\\frac{W}{P}=\frac{8\times 1}{3\times 4}\\\frac{W}{P}=\frac{2}{3}

Now, expressing 'W' in terms of 'P', we multiply both sides by 'P. This gives,

W=\frac{2}{3}P

Therefore, the weight of whiskers is two-third times as heavy as piglio is.

mestny [16]
The answer is "0.56".

As <span> 56% of voters support funding a new community center, so
56/100 = 0.56.

A binomial experiment refers to a measurable test that has the accompanying properties: The trial comprises of n repeated trials. Every trial can bring about only two conceivable results. We call one of these results a win and the other, a disappointment. The likelihood of accomplishment, meant by p, is the same on each trial.

Step-by-step explanation:

x² - 13x + 30

x² - 10x - 3x + 30

x(x - 10) - 3(x - 10)

May you solve this for me?
shusha [124]

Answer: 23.94 cm

Step-by-step explanation: I am totally not sure if this is the answer, but think of it this way: Those are 2 semi circles. The formula for the area of a semi circle is A = π * r^2 / 2. For the semi circle with 6 cm, the radius is 3. So we can plug it in the formula. 3.14 * 3^2 / 2, which is 14.13. For the semi circle with 5 cm, the radius is 2.5. Again plug it in and it will be 3.14 * 2.5^2 / 2, which is 9.8125. Then, to get the total area, add the 2 final values together. 9.8125 + 14.13, which is 23.9425. Then it said "round to the nearest hundredth if necessary. We can round to the nearest hundredth, which is 23.94, so that would be the answer. That is just my thought process.

I am not really sure if it's the answer, but take a gander at my thought process and hopefully, you can agree with me.
