Answer:
Here we will use the relation:
Density = mass/volume.
We know that:
Mass = 1485g
Volume = 750L
Density = 1485g/750L = 1.98 g/L
We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.
Two "common" gases with densities similar to this one are:
Carbon Dioxide, with d = 1.977 g/L
Dinitrogen Monoxide, with d = 1.977 g/L
In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
Answer:
π =14 cm
Step-by-step explanation:
Given:
circumference of a circle =616 cm
pie(π)=22/7
circumference of a circle=πr^2
616=22/7 *r^2
616*7/22 =r^2
4312/22 =r^2
196=r^2
=r
14 =r
The factored form is (x - 8)(x + 2).
(x - 8)(x + 2)
x^2 + 2x - 8x - 16
x^2 - 6x - 16
Answer:
the absolute value is 3,-13
The correct answer is x = 20
