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.
Answer:
a.Angle. 3
Step-by-step explanation:
Angle 3 is complementary to angle 4.
Because 70+20=90°
Answer:
A.1 square and 4 triangles
Step-by-step explanation:
A pyramid has sides that are triangular faces and a base. In a square pyramid, the base is a square.
The net therefore has 1 Square and 4 Triangles.
A net is given in the attached diagram:
Answer:
Option 2 is correct.
Step-by-step explanation:
Given the coordinates of lines segment (3, 10) and (7, 8). we have to find the mid-point of given line segment.
Mid-point formula states that if
and
are the coordinates of end points of line segment then the coordinates of mid-point are

∴ Coordinates of mid-point of line segment joining the points (3, 10) and (7, 8) are

Hence, option 2 is correct.
