4a) The length of WY is congruent to the length of WX so set them equal and solve for n.
5n - 2 = 2n + 7; add 2 to both sides
5n = 2n + 9; subtract 2n from both sides
3n = 9; divide both sides by 3
n = 3; substitute 3 in for the value of n
2(3) + 7 = WY
6 + 7 = WY
13 = WY
4b) First find the value of KN by using the pythagorean theorem (a² + b² = c²) so the value of KN is 17² = 14² + KN² or √19
Then you can use that value to find the value of NL using pythagorean theorem again. 17² = √19² + NL² or √270.
To find OL, divide √270 by 2 to get approximately 8.22
Hope this helps!!
***I actually just realized that the measure of NL is 14 and 1/2 of 14 is 7 so 7 is probably more accurate***
Answer:
(-3,5) ia the answer
Step-by-step explanation:
It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.
Answer:
90 men
Step-by-step explanation:
just keep the ratio constant
3:7
equals 10 parts
300/10=30
3*30:7*30
90 men and 210 women
hope this helps!!! :)
Hello there,
The time it takes an excursion boat to travel 36 miles downstream is the same as the time it takes the boat to travel 12 miles upstream. If the stream is 4 miles per hour, which of the following is the speed of the boat in still water.
Answer: 8 m/h
Answer:the price now is $128
Step-by-step explanation:
you can get this by dividing the cost by the percentage it has risen by. For example: 120 / 15 = 8 and then you add 8 to the initial price
