Hint: The rule of the 45-45-90 triangle is that both sides are x and the hypotenuse is x√2.

x = 5√2

To find the hypotenuse you multiply x by √2.

5√2 (√2)
5√4
5 (2)
10

The hypotenuse is 10.

The pythogorean theroem says that a^2+b^2=c^2, where a and b are legs of the right triangle and c is the hypothnuse. Therefore, when you add 5 times sqrt 2 and the other number sqrt 2 (i can't see it ) then it should get you 5+x=c^2. Then you add the two numbers and sqrt the sum. Because I can't see the other number, that's the best I can do.

That would be D. The first two would be fight (I think) except they don't include turning the calculator on. C is just plain wrong. D has all the right keystrokes.

Which of the following inequalities matches the graph? (1 point)

Aleksandr [31]

Answer: 2x + y < 7

Step-by-step explanation:

In the graph we can see that:

The line is a dashed line, and the shaded area is below the dashed line, then we will have something like:

y < a*x + b

We also can see that the slope of the line is negative, and that the y-intercept is +7

Then the inequality will be something like:

y < a*x + 7

Now we can see that the line passes through the points (0, 7) and (3, 1)

Then the slope will be:

a = (1 - 7)/(3 - 0) = -6/3 = -2

that is negative, as we already said.

Then we have:

y < -2*x + 7

we can rewrite this as:

2x + y < 7

This is the first solution shown.

URGENTEE. NON SO RISOLVERE QUESTO PROBLEMA.

Marrrta [24]

the question in English

Draw a rectangle having the base congruent to the nine sevenths of the height.

Let

b-------> the base of rectangle

h-------> the height of rectangle

we know that

b=(9/7)*h-------> this is the equation to obtain the base of the rectangle for a given height

examples

1) for h=7 units

b=(9/7)*7-------->b=9 units

the dimensions are 9 units x 7 units------> see the attached figure

2) for h=5 units

b=(9/7)*5-------->b=(45/7) units

the dimensions are (45/7) units x 5 units

The answer in Italian

Facciamo

b-------> base del rettangolo

h-------> altezza del rettangolo

Noi sappiamo che

b=(9/7)*h-------> questa è l'equazione per ottenere la base del rettangolo per una determinata altezza

esempi

1) per h=7 units

b=(9/7)*7-------->b=9 units

le dimensioni sono 9 units x 7 units-----> vedere la figura allegata

2) per h=5 units

b=(9/7)*5-------->b=(45/7) units

le dimensioni sono (45/7) units x 5 units
