Answer:  12.5 CC

Step-by-step explanation:

V=1/3Bh where B is the area of the base and h is the height

The perimeter of the square base is 8.6 so each side is 2.15 and the area of the base is (2.15)^2 or 4.6225

V=1/3(4.6225)(8.1)=12.5cc

The value of interior angle x for the given pentagon if found as 88 degrees.

<h3>What is termed as the pentagon?</h3>
  • A pentagon is a two-dimensional polygon with 5 sides and 5 angles.
  • This shape should have five sides and form a closed two-dimensional figure.
  • A closed figure consists of each of its sides intersecting to form vertices.
  • Five diagonals connect the five vertices to one‘s opposite vertices in a pentagon shape.
  • Each interior angle in a regular pentagon is 108°, so each exterior angle is 72°.

For the given question;

The exterior angles of the pentagon are given in figure.

Find all the interior angles for given angles using linear pair as all are straight lines.

  • 180 - 62 = 118
  • 180 - 33 = 147
  • 180 - 114 = 66
  • 180 - 59 = 121

The sum of all the interior angle of pentagon is 540.

Thus,

118 + 147 + 66 + 121 + x = 540

x = 540 - 452

x = 88

Thus, the value of interior angle x for the given pentagon if found as 88 degrees.

What is the percentage of the given number 35/50
mamaluj [8]
It is 70%, to calculate you want to get your denominator to be 100 (for 100%) and in order to get that you must multiply by two (whatever you do to the bottom you must do to the top) so, you get 70/100%

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f
AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = 15+22+16 = 53\ flyers

Number f flyers remaining is equal to Total number of flyers minus number of flyers already distributed.

Number of flyers remaining = 75-53= 22\ flyers

Number of volunteers remaining  =2

Now we will find number of flyers remaining each volunteers would get.

number of flyers remaining each volunteers would get is equal to Number of flyers remaining divided by Number of volunteers remaining.

framing in equation form we get;

number of flyers remaining each volunteers would get = \frac{22}{2}=11\ flyers

Hence the remaining volunteers would get 11 flyers each.
