Answer:
The triangles are congruent by SAS.
Step-by-step explanation:
The triangle have two congruent sides because it is given. The congruent angle is the angle at which they connect, these two angles are congruent because they are vertical angles.
<u>Answer</u>
$1,400
<u>Explanation</u>
The original price = 100%
After the discount the selling price = (100-25)=75% of the original price.
75% ⇒ $1050.00
100% ⇒ ?
From here you cross multiply
Original price = (100% × $1050.00)/75%
= 105,000/75
= $1,400
You multiply 2 both equations and move 14x to left
Answer:
17.1
Step-by-step explanation:
1. Find the Mean
(25+40+35+25+40+60+75)/7 = 42.9
2.For each number, subtract the Mean and square the result.
(25-42.86)^2=319
(40-42.86)^2=8.2
(35-42.86)^2=61.8
(25-42.86)^2=319
(40-42.86)^2=8.2
(60-42.86)^2=293.8
(75-42.86)^2=1033
3. Find the Mean of those squared differences.
(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9
4.Take the square root of that and this is what you want.
square root of 291.9 = 17.1
