1km = 1000m
1hr = 3600sec
Do proportions:
1km / 1000m = 15km / x
15000m = x
1hr = 3600sec 
15000/3600 = 4.2m per second

Answer:
Step-by-step explanation:
1/4 x 20x - 1/4 x 28<2x - 6 + 2
5x - 28/4<2x - 4
5x - 2x<-4 + 28/4
3x<-4/1 + 28/4
3x<-16 + 28/4
3x<12/4
3x<3
3x/3<3/3
x<1
 
        
             
        
        
        
7. honestly not 100% sure. i did 364 divided by 13 which was 28 so 28 flowers per table. and then 28 divided by 4. 7 flowers per vase.
        
             
        
        
        
Answer:
ΔEFG is an isosceles triangle.
Step-by-step explanation:
Given:
 E (0, 0), 
F (−7, 4),
G (0, 8)
ΔEFG
Solution:
Distance formula
Distance d = 
Step 1: Finding the length of  EF
By using distance formula,



Step 2: Finding the length of  FG
By using distance formula,

Step 2: Finding the length of  GE

Thus we could see that the sides EF = FG
So it is  a isosceles triangle.
