Answer:
old per: 1280
new per:2560
Step-by-step explanation:
first perimeter u get it by adding all the sides and since its a square  then all the sides are equal so u can just do 
320*4 which is equal to 1280
and by doubling the sides u can just double it in the old equation meaning
(320*2)*4
which is equal to 2560
 
        
                    
             
        
        
        
Answer:
Karl works 7 hours a week
Step-by-step explanation:
Step 1: Determine total amount that Sally earns
Total amount Sally earns=rate per hour×number of hours worked(h)
where;
Rate per hour=$7 per hour
Number of hours worked=h
Replacing;
Total amount Sally earns=(7×h)=7 h
Step 2: Determine total amount Karl earns
Total amount Karl earns=rate per hour×number of hours worked
where;
rate per hour=$5
number of hours worked=2 more than Sally=h+2
replacing;
Total amount Karl earns=5(h+2)
Step 3: Equate Sally's total earnings to Karl's total earnings and solve for h
7 h=5(h+2)
7 h=5 h+10
7 h-5 h=10
2 h=10
h=10/2
h=5
Karl works (h+2) hours=(5+2)= 7 hours
Karl works 7 hours a week
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1. There is a total of 16 outcomes
2. To get outcomes with a sum GREATER than 5, we have
2+4, 3+3, 3+4, 4+2, 4+3, 4+4 for a total of 6 outcomes.
3. To spin the same number twice, the possible outcomes are
1-1, 2-2, 3-3, 4-4 for a total of 4 outcomes.
