Well the formula for a perimeter of a triangle is 2(lxw) so the length here is 10 i think (just count the cubes on the bottom) then with that number you multiply that by the width (side) then multiply by 2. i counted ten on the length and 5 on the width (im not sure if thats how any because its hard to cound on a tiny grid on a computer hehe), so i multiplied 10 x 5 and got 50, then multiply by 2, i got 100. im not sure, but ill double check :)

Whats bigger 81.9 or 91.91
andriy [413]
It would be 91.91 because it is closer to 100, or any other greater number than 81.9 is. You could also look at it as, when you count, the number that you say first, is the smallest. So in this case, you'll say 81 before you say 91.

Hope you understand it in the way that I meant it. (:

Kareen bought 12 pencils for $2.16. At the same unit price, how many pencils could he buy with $4.50?
Bumek [7]

First, you want to find the price per pencil:

2.16/12=0.18

Then divide $4.50 by price per pencil:

4.50/0.18=25

He could buy 25 pencils with $4.50.

The table below shows the distribution of students who speak some Ghanaian languages.
melisa1 [442]

Answer:27.78% ; Twi; 1/3

Step-by-step explanation:

Given the data :

Language - - - - - - - Number of students

Nzema - - - - - - - - - - - 5

Ga - - - - - - - - - - - - - - - 20

Twi - - - - - - - - - - - - - - - 30

Ewe - - - - - - - - - - - - - - - 25

Fante - - - - - - - - - - - - - - 10

1.) To prepare pie chart:

Total number of students :

(5 + 20 + 30 + 25 + 10) = 90 students

Nzema: (5/90) × 360 = 20

Ga : (20/90) × 360 = 79.99 = 80

Twi : (30/90) × 360 = 119.99 = 120

Ewe : (25/90) × 360 = 79.99 = 100

Fante : (10/90) × 360 = 39.99 = 40

Total = 360

Pie chart is attached in the picture below

2)Percentage students that speak Ewe = (25/90) * 100 = 27.78%

Or (100/360) * 100 = 27.78%

3.) Modal language : This is the language spoken by majority of the students = Twi

4.) Fraction of student that speak either GA or Fante :

(GA or Fante) = (20 + 10) / 90 = 30/90 = 1/3
