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
Step-by-step explanation:
60/360 x 90 = 15
the answer is B
An expression represents the perimeter, in centimeters, of this triangle is 6q + 8r - 5s.
<u>Given the following data:</u>
- b = (5q - 10s) centimeters.
- c = (5s + 7r) centimeters.
<h3>What is a triangle?</h3>
A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
<h3>How to calculate the perimeter of a triangle?</h3>
Mathematically, the perimeter of a triangle can be calculated by using this formula:
P = a + b + c
<u>Where:</u>
a, b, and c are length of sides.
Substituting the given parameters into the formula, we have;
P = q + r + 5q - 10s + 5s + 7r
P = 6q + 8r - 5s centimeters.

Answer and explanation:
If a map is being reduced to form a pocket sized version then it is being proportionality reduced a smaller size that is required. Cartographers enlarge and reduce maps proportionally to serve different purposes in their study. The map is still the same but smaller in size.
If on a map 2cm represents 2 meters, that is 0.02/2 which evaluates to 1/100, then we are comparing distance and ensuring they are proportional using scale factor(our scale factor is 1:100 here)
