For this case, the first thing we must do is find the total area.
 We have then:
 A1 = (11) * (13) = 143 feet ^ 2

A2 = (11) * (19) = 209 feet ^ 2

 A3 = (11) * (13) = 143 feet ^ 2

A4 = (11) * (17) = 187 feet ^ 2
 Then, the total area is: A = A1 + A2 + A3 + A4

 Substituting values:
 A = 143 + 209 + 143 + 187

A = 682 feet ^ 2
 The number of gallons is: N = 682/180

N = 3.79
 Round to the whole whole integer: N = 4 gallons

 Answer:
 the homesellers would have to buy 4 gallons

Answer:

  $311.74

Step-by-step explanation:

A financial calculator computes the payment amount to be $311.74.

___

Your graphing calculator may have the capability to do this. Certainly, such calculators are available in spreadsheet programs and on the web.

___

The appropriate formula is the one for the sum of terms of a geometric series.

  Sn = a1·((1+r)^n -1)/(r) . . . . . where r is the monthly interest rate (0.005) and n is the number of payments (480). Filling in the given numbers, you have ...

  $620827.46 = a1·(1.005^480 -1)/.005 = 1991.4907·a1

Then ...

  $620827.46/1991.4907 = a1 ≈ $311.74

dsp73
The area of polygon D is given by:
 Ad = k ^ 2 * Ac
 Where,
 k: scale factor
 Ac: area of polygon C
 Substituting the values we have:
 Ad = (1/2) ^ 2 * (40)
 Ad = (1/4) * (40)
 Ad = 10 square units
 Answer:
 
the area of Polygon D is:
 
Ad = 10 square units

In the question some data is missing, that's value can be defined as follows:

Values:

\ X =  3.3 \\

\mu \ = 2.8 \% \\\sigma = 0.6

Formula:

z= \frac{X - \mu }{\sigma} \\

  = \frac{3.3 - 2.8 }{0.6} \\\\= \frac{ 0.5}{0.6} \\\\= \ 0.83

yarga [219]

Answer:

<h2>The right side triangle is isosceles and equilateral.</h2>

Step-by-step explanation:

In this problem we need to draw isosceles triangles with AB=AC. The triangle is attached.

Also, we have to identify which triangle is isosceles based on the image. The triangle on the left is isosceles and equilateral. Remember that a isosceles triangle is defined by the congruence between at least two sides, in this case, we have three congruent sides, which makes the triangle isosceles and equilateral.

The triangle on the right side is not isosceles, it's just a right triangle. When a right triangle is also isosceles, its acute angles are 45°, which is not the case here.
