When rounding to the nearest hundred, which of the following numbers round to 400?

2 answers:

6 0

When rounding numbers up or down, you need to look at the number in the place to the right of the place you are rounding to.

You have been asked to round to the nearest hundred (3rd place from the right)

Look one place to the right of the hundred place (the ten's place in this instance). If it is 4 or less, you will leave the hundred's digit as is and fill in the tens and ones places with a zero (this is called rounding down).

If it is 5 or higher, you will "round up" the digit in the hundred's place to the next hundred.

348 has a 4 in the tens place - so we will "round down" by leaving the hundred digit and placing zeros in the tens and ones. (300)

452 rounds up to 500 (because of the 5 in the tens place)

325 rounds down...

423 rounds down...

351 rounds up to ... 400! We found our answer

445 rounds down...

The answer is 423 since it's the closest number to 400 from all the numbers listed above.

The numbers 351 and 445 would also round to 400 but they are not the closest ones.

Hope it helped,

Find the Perimeter & Area for the following circle.

Feliz [49]

Answer:

A = 28.3 cubic inches; P = 20.1 inches

Step-by-step explanation:

Looks like 3/4 of a full circle

The area of a circle is calculated with the formula: $\pi r^{2}$

Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.

The radius is given as 3 inches

Area = $3.14*3^{2} = 3.14*9 = 28.26$ cubic inches = 28.3 cubic inches

------------------------

Perimeter is calculated with $2\pi r$ .

But this is 3/4 of a circle with an additional two 3-inch sides

Perimeter = $\frac{3}{4}*2\pi r$ + 2(3) = 14.1 + 6 = 20.1 inches

What is the probability that a 13-card bridge hand contains all cards from the same suit?

slega [8]

The total number of 13-card hands that can be dealt is 52C13. Four of these are of the same suit. Therefore the required probability is given by:
$\frac{4}{52C13}= 6.3\times 10^{-12}$
