Answer:

12 sides

Step-by-step explanation:

Given that :

Two of the exterior angles are = 60

The rest are each 24 ;

Find n, the number of sides of the polygon

The sum of the exterior angles of a polygon = 360

2 of the angles are 60° each ;

360 - (2 * 60)

360 - 120 = 240°

The remaining sides are 24° each ;

Hence, number of sides that are 24°

240° / 24° = 10 sides

Hence, total number of sides :

10 sides (14° each) + 2 sides (60° each)

10 + 2 = 12 sides

A prism is filled with 70 cubes with a side length of 1 2 unit. What is the volume of the prism in cubic units? Enter answer as
galina1969 [7]

Answer:

The volume of the cube is;

8\dfrac{3}{4} \ cube \, units

Step-by-step explanation:

The parameters of the prism are;

The number of cubes used to fill the prism, n = 70 cubes

The side length of each cube, s = 1/2 unit

The volume of the cube, V = n × s³

∴ Therefore, the volume of the cube, V = 70 × (1/2)³ = 8\dfrac{3}{4} \ cube \, units = 8.75 cube unit

Some 1 plz HELP!<br> 3 5/6 X 4 4/5<br> (plz include instructions if u can thx!)
rewona [7]
Well convert 3 5/6 to 23/6 and 4 4/5 to 24/ 5
then find a multiple that both 5 and 6 have which is 30
23x5= 115 and 24x6= 144
so 115 x 144= 16560/30
16560/30 = 552 /1 so your answer is

Aleksandr [31]

Answer:

Is the w2, w(2) or

{w}^{2}

?

If it's w(2) the answer is -4--8+1=-4+8+1=5

if it's w^2 then the answer would be 4--8+1=4+8+1=13

During a basketball practice, Mai attempted 49 free throws and was on 25% of them. How many successful free throws did she make?
Brrunno [24]

Mai made 12 successful free throws.

Step-by-step explanation:

Given,

Free throws made by Mai = 49 free throw

Successful throws = 25%

Number of successful throws = 25% of free throws

Number of successful throws = \frac{25}{100}*49

Number of successful throws = \frac{1225}{100} = 12.25

Rounding off to nearest whole number;

Number of successful throws = 12

Mai made 12 successful free throws.

In reciprocal is the denominator one unit
docker41 [41]
Not always if you're saying it will always be something like 1/2 becomes 2/1 with a unit of one. It's just flipped, so 2/6 will be 6/2, 4/5 becomes 5/4, 22/16 becomes 16/22 etc. That is all there is to it. Make sure you simplify your answers.
