You are attempting to estimate the number of protester marching through the city

Mathematics

9514 1404 393

Answer:

  1000

Step-by-step explanation:

If the number of protesters per minute remains a constant, then you could write the proportion ...

  p/12 = 177/2.1

Multiplying by 12 gives ...

  p = 12(177/2.1) ≈ 1011.4

Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:

 1010 protesters

It is probably sufficient to report the number to 2 significant figures*:

  1000 protesters

_____

* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.

It says write the following using am or pm
777dan777 [17]
The answer would be am because it says 1/4 to midday and midday is 12 and 12 is when pm starts so it would be am. 

Hope this helps! :)

Which inequalities are true? Check all that apply. Three-fifths < 0 Four-sixths greater-than one-half Nine-elevenths < 1 T
Kipish [7]

\frac{3}{5} < 0

\frac{8}{16} > \frac{1}{2}\\\\

<em><u>Solution:</u></em>

<em><u>We have to find the inequalities that are true</u></em>

<em><u>Option 1</u></em>

\frac{3}{5} < 0\\\\0.6 < 0

0.6 is not less than 0

Thus this inequality is not true

<em><u>Option 2</u></em>

\frac{4}{6} > \frac{1}{2}\\\\0.667 > 0.5

0.667 is greater than 0.5

Thus this inequality is true

<em><u>Option 3</u></em>

\frac{9}{11} < 1\\\\0.818 < 1

0.818 is less than 1

Thus this inequality is true

<em><u>Option 4</u></em>

\frac{8}{16} > \frac{1}{2}\\\\

0.5 = 0.5

Thus the above inequality is not true

A mirror is in the shape of an isosceles right triangle and has a hypotenuse length of seven times the square root of two. What
frez [133]

The length of one of the legs  of an isosceles right triangle and has a hypotenuse length of seven times the square root of two is 7 units.

<h3>What is an Isosceles triangle?</h3>

Isosceles triangles are triangles that has two of it sides equal to each other. The base angles of an isosceles triangle are equal.

The  isosceles triangle is also a right angle triangle. The hypotenuse is the longest side of a right angle triangle.

Therefore,

hypotenuse = 7(√2)

let the length of the other legs = x

Therefore, using Pythagoras theorem

c² = a² + b²

(7(√2))² = x² + x²

49 × 2 = 2x²

98 = 2x²

x² = 98 / 2

x = √49

x = 7 units
