Distinguish between rote and rational counting

1 answer:

6 0

Answer: There is a difference between rote counting and rational counting. Rote counting involves the memorization of numbers. Rational counting tells children "how many there are." For children to count rationally, they need to demonstrate one-to-one correspondence.

Answer:

Exact volume = 294π in³

Approximate volume = 923.6 in³

Explanation:

The volume of a cylinder can be calculated using the following rule:

volume = πr²h

where r is the radius and h is the height of the cylinder

In the given cylinder:

radius = r = 7 in

height = h = 6 in

Substitute with the givens in the formula to get the volume:

Volume of cylinder = πr²h = π(7)²(6) = 294π in³ ≈ 923.6 in³ to the nearest tenth

Hope this helps :)

12. Volume of a cube is 648V3 cm³. Find its total surface area.

AleksAgata [21]

Answer:

area= 449.2984 cm^2 if I understand correctly that the volume is 648 cm^3

Step-by-step explanation:

side length=the cube root of 648

side length=8.6535 cm

area=8.6536x8.6535x6=449.2984 cm^2

One of the rules of logarithms is as follows;

$\begin{gathered} \log _ab=x \\ Is\text{ equivalent to,} \\ a^x=b \end{gathered}$

We can now insert the corresponding values in the question provided, as shown below;

$\begin{gathered} \log _2\frac{1}{16}=-4 \\ \text{This is equivalent to,} \\ 2^{-4}=\frac{1}{16} \end{gathered}$

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

$a^{-x}=\frac{1}{a^x}$

Therefore, our equation can now be re-written as follows;

$\begin{gathered} 2^{-4}=\frac{1}{16} \\ \frac{1}{2^4}=\frac{1}{16}^{} \\ \frac{1}{16}=\frac{1}{16} \end{gathered}$

However, the question requires the answer to be expressed in exponential form. Therefore,

$\log _2\frac{1}{16}=2^{-4}$

Find a counterexample to show that the following statement is false. The sum of two five-digit numbers is a six-digit number + i

Andrej [43]

Answer:

It not necessary that every time the sum of two five digit number is a six digit number.

Step-by-step explanation:

We are given the statement that sum of two five digit numbers is always a six digit number.

We have to give a counter example to show that the given statement is false.

It not necessary that every time the sum of two five digit number is a six digit number.

Example:

10,000 + 30,000 = 40,000

13,245 + 74,632 = 87,877

56463 + 26230 = 82693

50,000 + 50,000 = 1,00,000
