15,000
Since her interest is simple, it adds the 10% to the original amount.
So, we multiply her amount (10,000) by the interest rate (.1) and by the amount of years (5).
10,000 * .1 * 5= 5,000
This is how much she has gained from said interest. Adding this to 10,000 gives us 15,000, which is the amount she will have.
Another way to do this would be to make a chart/table:
Start: 10,000
1. 11,000
2. 12,000
3. 13,000
4. 14,000
5. 15,000
And thus, we get the same answer.
The 60th customer each day will get both a calendar and a toy, as 60/20 = 3 and 60/6 = 10
Answer:
y = -2x + 3
y = -1/2x + 5
Step-by-step explanation:
- So the best way to solve is to come up with two slopes, I'd prefer 2 perpendicular slopes because perpendicular lines only cross once hence one solution guaranteed
- so say we choose a slopeA = 2 and slopeB = -1/2, the slopes are perpendicular only if when you multiply them you get -1
- then we use the slope intercept form of an equation y = mx + b
- we make up two equations y = -2x + b and y = -1/2x + b , now we can just make up number for b so the two equations are
- y = -2x + 3
- y = -1/2x + 5
- Then we solve them by substituting for y so
- -1/2x + 5 = -2x + 3 and x = -4/3
- and then we put this to get y in either equation
- y = -2(-4/3) + 3
- y = 17/3
- So the equations work
Answer:
Angle E is 59
Angle U is 89
Step-by-step explanation:
Angle E: 35 + 86 = 121
180 - 121 = 59
Angle U: 29 + 62 = 91
180 - 91 = 89
Remember
aln(c)=ln(c^a)
and
ln(a)-ln(b)=ln(a/b)
so
3ln3-ln9=
ln(3^3)-ln9=
ln27-ln9=
ln(27/9)=
ln3
