Answer:
≈ 27 m
Step-by-step explanation:
Assuming the house is in the form of rectangle:
- Length = 17 m
- Width = 21 m
- Diagonal =?
As per Pythagorean,
- d = √l²+w² = √17² +21² = √289+441 = √730 ≈ 27 m
Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5

2.32E8
4.31E-13
4.31E-6
Answer:
2.32E8 = 232,000,000
2.32E9 = 2,320,000,000
Step-by-step explanation:
2.32E8 - - > 8 digits after the decimal point ; 232,000,000
2.32E9 - - > 9 digits after the decimal point ;
2,320,000,000
4.31E-13 - - > 13 preceeding 0's before digit '4' ; 0.000000000000431
4.31E-6 - - > 6 preceeding 0's before digit '4' ; 0.000000000000431
Parallel to the graph of y = -2/3x + 5
means that it has the same slope
Rewrite
y = -2/3x + b
plug in the given coordinates to solve for b
5 = -2/3(-3) + b
5 = 2 + b
subtract 2 from both sides
3 = b
plug that back into the equation
y = -2/3x + b
y = -2/3x + 3
The answer is <span>B. y= -2/3x+3</span>
This line is parallel to y = -2/3x + 5 and it passes the point (3, 5).
Hope this helps :)
