Answer:
LiNO3
Step-by-step explanation:
Lithium nitrate is an inorganic compound with the formula LiNO3.
4.) The dotted line on the trapezoid is one of the lines. As you can see, to the left of the line is a right triangle. The other line should be drawn on the right side of the trapezoid to section off the other triangle. Now there is a rectangle in the middle with dimensions of 8 cm by 6 cm, and two identical triangles on either side. To find their base length, we can subtract 8 from 12 to get 4. These difference represents the sum of the two triangles' bases. Since the triangles are identical, we can divide 4 in half to get a base of 2 cm for each triangle. Therefore the triangles both have dimensions of 2 cm by 6 cm.
To find the area, we can add together the areas of the triangles and rectangle. We use length times width to find the area of a rectangle, and we use one-half base times height to find the area ofo a triangle.
Rectangle: 8*6 = 48 cm^2
Triangle: 0.5*2*6 = 6 cm^2
So the area of the trapezoid is 48 + 6 + 6 = 60 cm^2
Answer:
22,500 =2p
Step-by-step explanation:
Because the price of the new car is the price of the old car times 2.
22,500 =2p
First you get P alone. P is being multiplied by 2 so you divide it by 2 so it cancels out.
11250 = p
When you do something to one side of the equation you do the same to the other side so they are still equal to each other.
Answer:
