Answer:
One ml is equal to a cm3, then
m=2.67g/cm3*30.5cm3
m=81.435g
If we divide this quantity by 1000 to pass this to Kg we get:
m=81.435/1000=0.081435kg
Step-by-step explanation:
Remember the formula of density is density=mass/volume, if we solve for mass we get:
mass=density*volume
Answer: The area is 15 square units
Step-by-step explanation: It is helpful to sketch the coordinates on a graph to get an idea of what the triangle looks like so you can see which side will be the base, and where to get the height. You will see that AB is the hypotenuse, it is a right triangle, so AC can be the base and BC is the height.
Use the differences in x-values of points C & A to get the length of the base: 2-(-3) is 5
Use the differences in y-values of points B & C to get the height:
4-(-2) = 6
Area = bh/2
A = 5×6/2 = 30/2
A = 15 square unts
Answer:
24 pink
84 blue
Step-by-step explanation:
2 + 7 =9
2/9 = x/108
108 ÷ 9 = 12
12 × 2 =24
24 pink
7/9 = x/108
108÷9 = 12
12 ×7 =84
84 blue
