Answer:
The density of the material must be at least 1.5 g/cm³.
Step-by-step explanation:
The volume for a pyramid is given by the following formula:
V = (1/3)*Abase*h
Where V is the volume, Abase is the base area and h is the height. For Alexis's pyramid, we have:
V = (1/3)*100*6 = 200 cm³
Since he wants the paperweigth to have a mass of at least 300 grams, the density must be at least:
density = mass/volume = 300/200 = 1.5 g/cm³
Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
Answer:
the answer her is 180 the second one
In a circle, the degree measure of an arc is the same as the measure of the central angle that intercepts it.
A full circle is 360 degrees.
Add all the measures and set equal to 360 degrees.
One angle measure is not given, but that angle has a mark and another angle has the same mark, so the angle whose measure is not give also measures -9x - 3.
-9x - 3 + x + 107 + (-6x + 8) + (-9x - 3) + (-13x - 1) = 360
-9x - 3 + x + 107 - 6x + 8 - 9x - 3 - 13x - 1 = 360
-36x + 108 = 360
-36x = 252
x = 252/(-36)
x = -7
