can you please help?

Answer:

52.36%

Step-by-step explanation:

First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%

Answer:

(-5, 3)

Step-by-step explanation:

Let O(x, y) be the centroid of the triangle.

The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.

The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.

For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:

[tex]x=\frac{3 + (-7)+(-11)}{3}=-5\\\\y=\frac{-3 + 9 + 3}{3} =3[/tex]

The centroid is at (-5, 3)

Multiply 3 and n, and 3 and 4.

Answer:

  (d)  80 square units

Step-by-step explanation:

As with many composite area problems, this can be worked any of several ways. The attached shows trapezoid ABCE, from which triangle CDE can be removed to get the desired area.

The relevant formulas are ...

  A = (1/2)(b1 +b2)h . . . . . . area of a trapezoid

  A= (1/2)bh . . . . . . . . . . . . area of a triangle

__

Here, the trapezoid has bases 12 and 2, and height 12, so its area is ...

  A = (1/2)(12 +2)(12) = 84 . . . . square units

The triangle has a base of 4 and a height of 2, so its area is ...

  A = (1/2)(4)(2) = 4 . . . . square units

Then the area of the desired figure is ...

  84 - 4 = 80 . . . . square units

Answer:

dimensions of the book are 2 in. by 24 in.    

Step-by-step explanation:

I assume the book is a rectangle

Let w = the width

     l = the length

A = lw = 48         P = 2w + 2l = 52

                                   w + l = 26

                                          l = 26 - w

w(26-w) =48

26w - [tex]w^{2}[/tex] = 48

[tex]w^{2} - 26 w + 48 = 0[/tex]

(w-2)(w -24) =  0

w = 2    or   w = 24

                           if w = 2, then l = 26 - 2 = 24

                           if w = 24, then l = 26 - 24 = 2

So, the dimensions of the book are 2 in. by 24 in.

Answer:

The answer is 9

Step-by-step explanation:

Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying

[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.

Answer:

30 centimeters every 15 months is correct the other one isnt.

Step-by-step explanation:

The rates are equivalent, and we can justify this by converting the time units to make a valid comparison.

To determine if the rates are equivalent, we need to compare the ratios of centimeters to time between the two rates.

Rate 1: 60 centimeters every 2.5 years

Rate 2: 30 centimeters every 15 months

Let's convert both rates to a common time unit to make a valid comparison. We can convert years to months or months to years.

Converting Rate 1:

2.5 years * 12 months/year = 30 months

Rate 1 becomes 60 centimeters every 30 months.

Now, let's compare the rates:

Rate 1: 60 centimeters every 30 months

Rate 2: 30 centimeters every 15 months

The rates are equivalent because the ratios of centimeters to time are the same for both rates. In both cases, the ratio is 2 centimeters per month.

Therefore, the rates are equivalent, and we can justify this by converting the time units to make a valid comparison.
