Answer:
84 cm²
Step-by-step explanation:
The figure has a uniform horizontal cross section, so its area is the product of that cross section length and its vertical dimension.
__
A = bh
A = (6 cm)(14 cm) = 84 cm²
The area of the shape is 84 square centimeters.
_____
Additional comment
You could decompose the figure into a rectangle with base 6 and height 8, and a parallelogram with base 6 and height 14-8=6. The area formula is the same for each: A = bh, so the area of the composite figure is ...
A = 6×8 +6×(14 -8)
= 6×(8 +(14 -8))
= 6×14 . . . . same as above.

Answers
Answer:
Here's your answer.
Let the number be x.
Here we have to multiply with 100 on both sides.
[tex] \implies \: 100x = 252.5252 \\ \\ \implies \: 100x = 250 \ + 2.5252... \\ \\ \implies \: 100x = 250 + x \\ \\ \implies \: 99x = 250 \\ \\ \implies \: x = \frac{250}{99} [/tex]
Therefore, sum of numerator and denominator = 25099 = 349

She finds the mean is 78. Her steps for finding the variance are shown below.
What is the first error she made in computing the variance?
Emi failed to find the difference of 89 - 78 correctly.
Emi divided by N - 1 instead of N.
Emi evaluated (46 - 78)^2 as -(32)^2.
Emi forgot to take the square root of -135.6.
Answers
The error she made is Emi evaluated (46-78)² as - (32)² is wrong.
What is variance?Variance is calculated as the average of squared differences of the data observations from the mean.
Given data: 87, 46, 90, 78, and 89.
Here, the first Emi find the difference of 89 - 78 correctly.
Now, Emi division is also correct.
Now, Emi evaluated (46 - 78)^2 as -(32)^2 is wrong.
(46-78)² = (-32)²
Here she used the negative sign outside.
Hence, Emi evaluated (46 - 78)^2 as -(32)^2 is wrong.

Suav left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 4 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 4 minutes. Then he drove home at a speed of 6 blocks every minute. Make a graph of showing the number of blocks away from home that Suav is xx minutes after he leaves his house, until he gets back home.
Answers
The graph for Suav's trip is attached along with the values derived from the information provided.
What is the explanation for the graph?The key to understanding the graph is that every time spent while he was on the way to the back and back are all added cumulatively.
So when he stops at the store which is 8 blocks away from home, the time spent is recorded as 4 + 2 at location 8 blocks.
It is also to be noted that the time spent is plotted on the x-axis and the blocks away from home on the y-axis.
