If c=12 find a right triangle 90 degrees 45 degrees 45 degrees

Answers

If is a triangle 90°, 45°, 45° then the sides are in ratio 1 : 1 : √2.

If c = 12 is a hypotenuse, therefore we have the equation:

$a\sqrt2=12\ \ \ \ |\cdot\sqrt2\n\n2a=12\sqrt2\ \ \ \ |:2\n\n\boxed{a=6\sqrt2}$

If c = 12 is a leg, therefore we have:

$\boxed{a=12\sqrt2}$

(14 POINTS!) Based On the information in the table, is the cost of the apples proportional to the weight of apples ?

Answers

Answer:

yes it is proportional, if you subtract 3.76 from 5.64 you get 1.88 then add 1.88 to each number to make sure it's right.

Answer:

The statement of whether the cost is proportional to the cost and weight of apples is: yes, it is proportional.

Step-by-step explanation:

From what I can find out from the graph, I would firstly likely want to see if there is a constant between each pound and cost. Meaning, I would want to see if there is a rule that is used throughout the table.

From what I had found out, the rule of this table is:

(x = pounds of apples)

(y = cost of apples)

y = 1.88x

This means that in order to get the 'y' value, also known as the cost of apples, we must multiply 1.88 to the 'x' values, pounds of apples.

This can be found by:

First, dividing 3.76 to 2, your quotient is: 1.88

$(3.76)/(2)=1.88$
