6) 
(CPCTC)
7) 
bisects 
(if a segment splits an angle into two congruent parts, it is an angle bisector)
Answer:
96 + x Less-than-or-equal-to 149
Step-by-step explanation:
no more than 149 people can board so if it was "more" than 149 then it would be incorrect.
D. 64x^9
This is because 4x^3 is the side length and you substitute it into l^3
and you get (4X^3)^3
(4X^3)^3 is the same as (4X^3) x (4X^3) x (4X^3)
1. (4X^3)^3
2. (4X^3) x (4X^3) x (4X^3)
3. (16X^6) x (4X^3)
(remember when multiplied, exponents get added to each other)
4. 64X^9
After multiplying all three of those you get 64X^9 D.

a. The simplest form is 1:60
b. The simplest form is 4:5
c. The simplest form is 1:50
d. The simplest form is 1:10
Step-by-step explanation:
a. 10 seconds to 10 minute
First we will convert the values in to same units for finding ratio.
Therefore;
one minute = 60 seconds
10 minutes = 60*10 = 600 seconds
Ratio;
Dividing both by 10
The simplest form is 1:60
b. 28 to 35
Ratio;
28:35
As both are multiples of 7, therefore dividing by 7
The simplest form is 4:5
c. 2cm to 1m
Converting in same units
1 m = 100 cm
Ratio;
2 : 100
Dividing by 2
The simplest form is 1:50
d. 30p to Rs. 3
Converting in same units
1 Rs. = 100 p
3 Rs. = 100*3 = 300p
Ratio;
30:300
Dividing both by 30
The simplest form is 1:10
