I) 80% x 5640 = Rs. 4512
ii) 4512 divide by 50 = Rs. 90.24
Answer:
A) R = 1900 -24t
B) 1684 billion barrels
C) 79.17 years
Step-by-step explanation:
<h3>A)</h3>
Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.
R = 1900 -24t
__
<h3>B)</h3>
For t=9, the reserves will be ...
R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels
__
<h3>C)</h3>
The reserve will be 0 when ...
0 = 1900 -24t
24t = 1900 . . . . . add 24t
t ≈ 79.17 . . . . divide by 24
Reserves will be gone in about 79.17 years.
“C” Os the correct answer
The three stages that have to do with fluency, progression and automaticity are found in the Number Sense and Operations .
<h3>What is the number sense and operation strand of mathematics?</h3>
This is the part of mathematics that is known to teach the student basic ways to carry out number operations in mathematics. This has to do with representation of numbers as well as solving for the existing relationships in these numbers.
Having a sense of numbers is a very important ability skill that has to be developed early is students to enable them progress in the subject.

Answer:
y=-x-4
Step-by-step explanation:
You can write the equations in point-slope form first.
1) y+3=-(x+1)
2) Then you can convert it into slope intercept form
3) y=-x-1-3
4) y=-x-4
