Answer:
B.
Step-by-step explanation:
Let's call x the number of pens and y the number of notebooks that Monique can buy.
If each pen costs $2 and each notebook costs $3, so she is going to spend 2*x on pens and she is going to spend 3*y on notebooks.
Additionally, she is going to spend a maximum of $36. so:
2x + 3y 36
It means that the line that separated the region is:
2x + 3y = 36
This is the same that a line that passes for the points (0,12) and (18,0) or the line of the region B
Answer:
The 30% of a number can be calculated multiplying that number by 0.3, so, if we call the number we don't know x, we can write this equation:
0.3x = 12
And then solve it for x::
x = 12/0.3 = 40
So now we know that the number is 40.
We can replace the 40 in the equation to get if our answer is correct or not..
30% of 40: 0.3 * 40 = 12
And then, we see it's correct
Area of the square:
s* s
Area of the triangle:
0.5*s*l
You have one square plus 4 triangles
1(s*s) + 4(0.5*s*l) = s^2 + 2sl
Your answer will be C
Answer: can you give us some choices
Step-by-step explanation:
P (Principal) = $5000
I (Interest) = $6050 - $5000 = $1050
T (Time) = 3 1/3 years or 40 months
Formula:
I = (PRT)/100
manipulate this and you’ll get:
R = (100I)/PT
Plug in the values:
R = (100 * 1050)/(5000 * 3 1/3)
R = 105000/16666
R = 6.3
Hence, the annual interest rate is 6.3%.
However, I did not understand whether you want the annual interest rate or monthly interest rate.
If you require monthly interest rate, then just put T (Time) = 40, to signify 40 months.
Hope this helps
