Answer:
its true, depending on the times table.
From question,
lacy learned 34 recipes in 17 weeks,
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in
= 40*2
=80 recipes.
400 miles per hour is a rate. For every hour, the airplane travels four hundred miles.
Knowing this, If the plane travels for three hours, we use a simple multiplication equation to represent this problem.
400 x 3 = 1200
The plane traveled 1200 miles, if it traveled at a speed of four hundred miles for three hours.
Answer:
The answer is 17ft hope this helps
Step 1
The property of a parallelogram is that diagonals of a parallelogram bisect each other and hence have the same midpoint.
This means that the diagonals cut themselves into two equal halves.
Hence, they must have the same mid-points.
Therefore, if we prove that AC and BD have the same midpoint, then ABCD is a parallelogram.
Step 2
Find the midpoint of BD and AC
![\begin{gathered} (\frac{x_2+x_1}{2}),(\frac{y_2+y_1}{2}) \\ BD=(-\frac{1}{2},\frac{9}{2}) \\ AC=(-\frac{1}{2},\frac{9}{2}) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28%5Cfrac%7Bx_2%2Bx_1%7D%7B2%7D%29%2C%28%5Cfrac%7By_2%2By_1%7D%7B2%7D%29%20%5C%5C%20BD%3D%28-%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B9%7D%7B2%7D%29%20%5C%5C%20AC%3D%28-%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B9%7D%7B2%7D%29%20%5Cend%7Bgathered%7D)
Since they have the same midpoint, the answer will be;
We Prove that AC and BD have the same midpoint which we have done. we know the diagonals of a parallelogram bisect each other; therefore, they have the same midpoint and ABCD is a parallelogram.
