The area of each triangular face is 40 square feet

<em><u>Solution:</u></em>

Given that,

Square pyramid has a base area of 64 square feet

The pyramid’s total surface area is 224 square feet

The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base

<em><u>Therefore, total surface area of square pyramid is given as,</u></em>

Total surface area = base area + 4(Area of traingular face)

Let "x" be the area of each traingular face

224 = 64 + 4(x)\\\\224 - 64 = 4x\\\\4x = 160\\\\x = 40

Thus area of each triangular face is 40 square feet

David pays $335 in advance on his account at the gym. Each time he visits the gym , $6 is deducted from the account. Write an eq
Korolek [52]

Answer:

x = 335 - (6 * v)

Step-by-step explanation:

In order to calculate the value remaining, we need to first multiply the daily cost of each visit by the number of visits made to the gym which is represented by the variable (v). Once we have this cost of all the days then we subtract this amount from the current account balance in order to get the new remaining balance which is represented by x.

x = 335 - (6 * v)

Sv is an angle bisector of rst. If mrsv = (3x+5) and mrst = (8x-14), find x.
MA_775_DIABLO [31]

m∠RSV = 3x + 5, m∠RST = 8x - 14       <em>given</em>

m∠RSV ≅ m∠VST                                 <em>definition of segment bisector</em>

m∠RSV + m∠VST = m∠RST                 <em>angle addition postulate</em>

(3x + 5) + (3x + 5) = (8x - 14)                  <em>substitution</em>    

6x + 10 = 8x - 14                                    <em>simplify (added like terms)</em>

       10 = 2x - 14                                    <em>subtraction property of equality</em>

      24 = 2x                                           <em>addition property of equality</em>

      12 = x                                              <em>division property of equality</em>

Answer: x = 12
