Mary crocheted a rectangular blanket whose diagonal measures approximately 7.21 feet. What are the most likely length and width

mote1985 [20]

Answer:

If both sides are integers, one side will be 4 feet and the other will be 6 feet. The other solution is the symmetrical solution (4 feet instead of 6 feet, and 6 feet instead of 4 feet).

Step-by-step explanation:

We have a rectangular blanket, that has a diagonal that measures h=7.21 feet.

The two sides of the rectangle a and b can be related to the diagonal h by the Pithagorean theorem:

$a^2+b^2=h^2$

Then, we can express one side in function of the other as:

$a^2+b^2=h^2\\\\a^2=h^2-b^2\\\\a=\sqrt{h^2-b^2}=\sqrt{7.21-b^2}=\sqrt{52-b^2}$

Then, if we define b, we get the value of a that satisfies the equation.

A graph of values of a and b is attached.

If both side a and b are integers, we can see in the graph that are only two solutions: (b=4, a=6) and (a=4, b=6).

He dot plots show the number of hours a group of fifth graders and seventh graders spent playing outdoors over a one-week period

garik1379 [7]

Answer:

The left side of the data looks similar to the right side in the seventh-grade data, but not in the fifth-grade data.

Step-by-step explanation:

In the seventh-grade data, we can split dots into two equal groups, one from 0 to 3 and the other one from 4 to 7. In the first group the dot distribution is {2, 2, 3, 5}. In the second group the dot distribution is {5, 3, 3, 1}. Then, the left side looks similar to the right side (they are symmetrical).

If we perform a similar division between dots for fifth-graders data, we obtain one group, from 1 to 4, which dot distribution is {2, 3, 1, 4}; and another group, from 5 to 8, which dot distribution is {5, 5, 2, 2}. Then, the left side doesn't look similar to the right side (they aren't symmetrical).
