Answer:
Step-by-step explanation:
length = 120/8 = 15 feet
perimeter = (15 + 8) x 2 = 46 feet
Answer:
Yes
Step-by-step explanation:
The lines of symmetry are the three altitudes.
Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
Answer:
10.
Step-by-step explanation:
You get this answer by doing 10 x 10, which is 100.
10 groups of 10 in 100.
Answer: 
Step-by-step explanation:
Given, A pizza is to be cut into halves.
Since half is represented by 
.
So each piece is now of the original.
if each of these halves is to be cut into sevenths, then the fraction of final pieces would be: 
or we can say each half is divides into 7 pieces since there are two halves, so there will be 2 x 7 = 14 peices.
And the fraction of the pizza is each of the final pieces = .
