The order you use the operations is pemdas.
 p stands for parentheses. e stands for exponents. m stands for multiplication. d stands for division. a stands for addition. s stands for subtraction. solve your operation to get your answer. I got 5 1/3

The area of one rectangle is twice the area of another. What is the ratio of their perimeters
Veronika [31]

Answer:

The answer is 8 units! Hope this helps!

Step-by-step explanation:f the length of any one side of the square is x, then the area is x2, and the perimeter is 4x. If the area is twice the perimeter, x2 = 2(4x), and x2 − 8x= 0. By factoring, we see this equation is equivalent to x(x − 8) = 0, which has solutions 0 and 8. The length cannot be 0, so it must be 8 units.

PLEASE HELP <br> WHAT ARE THE coordinates for the center of the hyperbola??
solong [7]

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center (x_0,y_0) is given by:

\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1

In this question, we have that:

-x_0 = -1 \rightarrow x_0 = 1

-y_0 = 3 \rightarrow y_0 = -3

The coordinates of the center of the hyperbola are (1,-3)

I don’t know how to use the triangle area to calculate the area of the inscribed polygons
Trava [24]

First of all, let's recall the area of a triangle, knowing its base (b) and height (h):

A = \cfrac{bh}{2}

The exercise is showing you that, if you inscribe a polynomial with more and more side, the area of the polynomial will approximate the area of the circle better and better (you can see youself that the polygon is "filling" the circle more and more as the number of sides increase).

Now, the second column tells you the area of each of the triangles the polygon is split into. So, we can see that the first polygon is split into 3 triangles, each of them having base 1.73 and height 0.5.

So, the area of each triangle is

A = \cfrac{1.73 \cdot 0.5}{2} = 0.4325

There are three of these triangles, so the area of the whole polygon is

A = 0.4325 \cdot 3 = 1.2975

In the second case, you have six triangles, each with base 1 and height 0.87. So, the whole area is

A = 6 \cdot \cfrac{1\cdot 0.87}{2} = 0.87 \cdot 3 = 2.61

Finally, in the last case you have 8 triangles, each with base 0.77 and height 0.92. So, the whole area is

A = 8 \cdot \cfrac{0.77\cdot 0.92}{2} = 0.77\cdot 0.92 \cdot 4 = 2.8336

Carlos has 32 envelopes and wants to deliver 3 envelopes to each class. How many classrooms will he visit?
statuscvo [17]

10 classrooms

With 2 left over.

It's a simple question, make sure that you know that the key is 32/3, and because it's not fully divisible use the whole number (10)
