Answer: Lis saved $1166.4 .
Step-by-step explanation:
Given , Ellen saved $2000 and she spent 10% of it to buy a bike.
Then, Ellen's left saving = saved amount - 10% of (saved amount)
= $2000 - 0.10 x $2000 <em>[We convert perecntage to decimal by diving it by 100]</em>
= $2000 - $200
= $1800
So, Ellen's left saving= $1800
Also, Kim saved 8% more than that of Ellen's left savings.
Kim's Saving = Ellen's left saving + 8% of (Ellen's left saving)
= $1800 + (0.08) x ($1800) <em>[We convert perecntage to decimal by diving it by 100]</em>
= $1800 + $144
i.e. Kim's Saving= $1944
If Lisa saved 60% as much as Kim, then Lisa's saving = 60% of (Kim's Saving)
= (0.60) x ($1944) <em>[We convert perecntage to decimal by diving it by 100]</em>
i.e. Lisa's saving = $1166.4
Answer:
13. A
14. C.
Step-by-step explanation:
A relation is a function if there is only one y assigned to each x.
That is if you have a set of points, there should be no repeated x value.
So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.
The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.
The y-intercept is where the graph goes through the y-axis at. It goes through at -1 so b=-1.
The slope is rise/run. So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works. You can do the counting if you want. You could also use the slope formula.
To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.
(0,-1)
-(3,1)
--------
-3 -2
So the slope is -2/-3 or just 2/3.
So the equation is y=2/3 x-1
C.
Answer:
76.7 liters
Step-by-step explanation:
You have ...
C1×V1 = C2×V2
so ...
V2 = V1×(C1/C2) = (115 L)×(14/21) = 76 2/3 L
V2 ≈ 76.7 L
Answer:
The correct option is c.
Step-by-step explanation:
The given equation is
The given inequality is
A point will contained in solution set if the above inequality satisfied by that point.
Check the point (0,-3),
This statement is false, therefore option a is incorrect.
Check the point (-3,0),
This statement is false, therefore option b is incorrect.
Check the point (3,3),
This statement is true, therefore option c is correct.
Check the point (-3,-3),
This statement is false, therefore option d is incorrect.
