Answer:
The lengths of AB and EF are 10 and 2 respectively
Step-by-step explanation:
The lengths of AB and EF are 10 and 2 respectively
If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;
AB/DE = BC/EF
5x/4 = 5/x
5x² = 20
x² = 20/5
x² = 4
x = 2
Since the value of x is 2, length of AB is 5x = 5(2) = 10
Since EF = x, hence EF = 2
The lengths of AB and EF are 10 and 2 respectively
write each of the following expressions as a power of two (4x2^5)\(2^3x1/16)

Answers
Answer:
Step-by-step explanation:
Rewrite as : (2^2 * 2^5) / (2^3 * 2^4)
= 2^7 / 2^(-1)
Note: Based on exponent rules you do 2 power 7 minus, minus seven. And 2 minus is a positive. So you do 2 power seven plus 2 power 1. That is 2 power 8.
= 2^8

In the 5 place, there is 0.
In the 25's place, there is a 2, which means 2*25=50
In the 125's place, there is a 1, 1*125=125.
125+50+3=178

If no justification for work, you shall get reported bc of spam of points. Thank you!!
Answers
Answer:
Step-by-step explanation:
Sky High $50 = 10 people so on $5 each person
Jump it up $70 fee then $2 per person
90 for 10 people at jump it up
100 for 15 people at jump it up
75 for 15 at sky high
110 for 20 people at jump it up
100 for 20 at sky high
118 for 24 people at jump it up
120 for 24 people at sky high
the minimum number of friends for it to be cheaper at jump it up is 24 friends since it would be $118 compared to $120 at sky high
the set up fee of 70 then 2 per friend compared to 50 for 10 to start then 5 each makes it come down to 24 friends in all for jump it up to be cheaper minimum anything lower sky high is cheaper
