If mark celebrated his 8th birthday 10 years ago then mark is 18 years old. Jess is twice as old as mark so Jess is 36 years old. Julie is 26 less than mark and jess combined so Julie is 28 years old. Gwen is two years older than Julie so Gwen is 30 years old. The twins are 2 less than 1/3 of gwen so the twins are 8 years old
-3*-2=6+3=9 you got that part right
3*-4=-12+9=-3
therefore 9>-3
If it is all calculated together correctly then the final answer would be 25%.
Since it is to the third, we move the decimal point three places over to the right:
4.16 ---> 4,160
What ever the power, move it over that amount.
If the power is negative,move it that amount to the left, making it smaller.
Hope this helps!
Answer:
A). Scale factor = 
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor = 
= 
= 
= 
Part B
Scale factor =
