Cheryl solved a problem: 84 ÷ 0.01 = 8,400.
Alexandra [31]

Answer:

Cheryl is correct.

Step-by-step explanation:

Cheryl solved a problem : 84 ÷ 0.01 = 8,400.

This is absolutely right.

When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.

To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.

\frac{84\times 10}{0.01\times 10} = \frac{840}{0.1}

to make divisor a whole number we will again multiply both the numbers by 10.

\frac{840\times 10}{0.1\times 10} = \frac{8400}{1} = 8,400

Now answer would be 8400.

Therefore, Cheryl is correct.

Lisa [10]
The accumulated (future) value is given by the formula
F=P(1+i)^n
where 
P=amount of deposit (made at the beginning of the first period)
i=monthly interest, APR/12 = 3%/12 =0.0025
n=number of periods (month)

For example, the future value for the 6th month is
F(6)=1000(1.0025^6)=1015.09  (to the nearest cent)

Here is a schedule of the values,
i=month
F(i) = value at the end of month i.

  i   F(i)
 0  1000.0 
 1  1002.5 
 2  1005.01
 3  1007.52
 4  1010.04
 5  1012.56
 6  1015.09
 7  1017.63
 8  1020.18
 9  1022.73
10 1025.28
11 1027.85
12 1030.42 + $50 deposit = 1050.42
All values are rounded to the nearest cent.

What is the lowest whole number for hypotenuse c when using the formula <img src="https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%2Bb%5E
nata0808 [166]

9514 1404 393

Answer:

  0

Step-by-step explanation:

If a=b, you are asking for a whole number c such that ...

  c = √(a² +a²) = a√2

If 'a' is a whole number, the only whole numbers that satisfy this equation are ...

  c = 0 and a = 0.

  0 = 0×√2

The lowest whole number c such that c = √(a²+b²) and a=b=whole number is zero.

__

√2 is irrational, so there cannot be two non-zero whole numbers such that c/a=√2.

_____

<em>Additional comment</em>

If you allow 'a' to be irrational, then you can choose any value of 'c' that you like. Whole numbers begin at 0, so 0 is the lowest possible value of 'c'. If you don't like that one, you can choose c=1, which makes a=(√2)/2 ≈ 0.707, an irrational number. The problem statement here puts no restrictions on the values of 'a' and 'b'.
