We know that the smaller base is x cm, the greater base is x+4 cm, and that the height is x/2 cm.
Since the area of a trapezium is given by
If we plug the expressions we have
If this must equal 84, we can solve for x as follows: start with
Multiply both sides by 4:
Subtract 336 from both sides:
We can divide both sides by 2 to make computation simpler:
Use the quadratic formula (or any mean you prefer) to solve this equation and get the solutions
We can't accept the negative solution, because it would imply
and we can't have negative side lengths. So, the answer is 12.
Answer:
W = 9 inches.
Step-by-step explanation:
The volume of a rectangular prism is given by
Where
w,h and l re width, height and length of rectangular prism
It is not mentioned that a box has a length of 18 inches and a height of 3 inches.
Using above formula.
So, the width of the box is 9 inches.
The linear equation B. y = -x +7.5 best describes the given model. The mood rating for a student that spent 5.5 hours online would be 2.
Step-by-step explanation:
Step 1; We plot the points that fall on the line and that lie on an exact x or y coordinate. The following 4 points are plotted (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4). We substitute the values of x in the given equations to see which best describes the model.
Step 2; When y = x + 7.5, we get the coordinates as (0.5, 8), (2, 9.5), (2.5, 10) and (3.5, 11).
When y = -x + 7.5, the coordinates are (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4).
When y = + 7.5, the coordinates are (0.5, 7.25), (2, 6.5), (2.5, 6.25) and (3.5, 5.75).
So equation 2 has the closest values to the actaul graph.
Step 3; By substituting x = 5.5, y = -(5.5) + 7.5 = 7.5 - 5.5 = 2.
