Answer: 3.2\times10^6\text{ mm}

=3.2\times10^5\text{ cm}

3.2\times10^3\text{ meters}

Step-by-step explanation:

We know that 1 kilometer = 1000 meters

Therefore, \text{3.2 kilometers =}3.2\times1000=3.2\times10^3\text{ meters}

Also, 1 meter = 100 cm

Therefore, 3.2\times10^3\text{ meters}=3.2\times10^3\times100

=3.2\times10^3\times10^2=3.2\times10^{3+2}\\\\=3.2\times10^5\text{ cm}......\text{[ by product law of exponent]}

Also, 1 cm = 100 mm

Therefore,

3.2\times10^5\text{ cm}=3.2\times10^5\times10\\\\=3.2\times10^{5+1}=3.2\times10^6\text{ mm}......\text{[ by product law of exponent]}

PLEASE HELP!
ELEN [110]

Answer:

Colin's mean score = 17.10

The new mean is 18.00

Step-by-step explanation:

Given scores: 31, 10, 26, 16, 28, 31, 9, 11, 8, 1

number of terms: 10

mean is calculated by given formula = sum of all the data set/ number of terms in the data set.

mean for the 10 scores = (31+ 10+ 26+ 16+ 28+ 31+ 9+ 11+ 8+ 1 )/10

                                       = 171/10 = 17.1

Colin's mean score = 17.10

____________________________________________

runs scored by Colin in 11th match = 27

number of terms: 11

new mean = new sum /number of terms

new mean = (old sum score + 27)/11 = (171+27)/11

new mean = 198/11 = 18

The new mean is 18.00

a teacher asked 3 pupils to choose any 2 digit number square it and then find the remainder after dividing the result by 7. Dori
gizmo_the_mogwai [7]
First write out all the two digit square numbers

4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81

Next divide all of them by 7

16/7 = 2 2/7 or 2 and 2 remainders
25/7 = 3 4/7 or 3 and 4 remainders
36/7 = 5 1/7 or 5 and 1 remainder 
49/7 = 7
64/7 = 9 1/7 or 9 and 1 remainder
81/7 = 11 4/7 or 11 and 4 remainders

This tells us that the only possible remainders for a two digit square number divided by 7 are 1, 2 and 4
If Doris got 6 and Horace got 3, they must have made a mistake.
