Answer:
615 centimeters
Step-by-step explanation:
Kate used 6.15 meters of ribbon to make a bow
The centimeters of the ribbon used by kate can be calculated as follows
1 meter=100 centimeters
6.15 meters= x
Cross multiply both sides
1 × x = 6.15 × 100
x = 615 centimeters
Hence Kate used 615 centimeters of the ribbon
Answer:
length: 12m
width: 2m
Step-by-step explanation:
24 = a*w
a = w+10
then:
24 = (w+10)w
24 = w*w + 10*w
24 = w² + 10w
0 = w² + 10 - 24
w = {-10±√((10²)-(4*1*-24))} / (2*1)
w = {-10±√(100+96)} / 2
w = {-10±√196} / 2
w = {-10±14} / 2
only positive numbers:
w = {-10+14}/2
w = 4/2
w = 2m
a = w+10
a = 2 + 10
a = 12m
Check:
24 = 12*2
