Well if one week is 7 days, and there are 42 days left, then 42 / 7 = 6 more weeks.

Hope this helps!

To answer this question, you will need to divide 42 by 7. There are 7 days in the week and 42 days left. Once divided, you will be left with the number 6. With that being said, there are 6 weeks left of school.

Answer:

${10}^{th} \: term = \frac{5}{512}$

Step-by-step explanation:

geometric progression formula:

${n}^{th} \: term = ar ^{n - 1}$

given:

common ratio, r = 1/2

$first \: term \: = 5$

1) find the value of a

${n}^{th} \: term \: = a {r}^{n - 1}$

we're finding the 1st term, so substitute 1 into n:

${1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1}$

first term is 5. so we substitute 5 into the equation:

$5 = a(1)$

$a = 5$

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

${10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1}$

${10}^{th} \: term = 5( \frac{1}{512} )$

${10}^{th} \: term = \frac{5}{512}$

Answer:

NI = 45

IG=28

HG^2 = NI^2 +IG^2

= 45^2 +28^2

=2025+784

= 2809

HG=53

CosG = IG/HG

= 28/53

= 0.52

The scientist would use milligrams, grams, and kilograms.

The best procedure would be to randomly pick 52 fish from the entire pond and weigh each of them as this would be the most unbiased way to achieve the average mass
