Answer:
x = 3
Step-by-step explanation:
ΔABC is 45 45 90 right triangle
The ratio of leg: hypo = a : a√2
Given: hypo AC = 6√2; so AB = BC = 6
ΔBCD is 30 60 90 right triangle
The ratio of short leg : long leg : hypo = x : x√3 : 2x
Hypo. BC = 6 = 2 (3)
So short leg BD = x = 3
Answer:
since 3x^2-7x+4=0 is in the form ax^2+bx+c=0, a=3, b=-7, c=4
Answer:
x = 14 cm
Step-by-step explanation:
200 000 cm = 2 km
1 cm ............... 2km
x cm ..............28 km
x = 28*1/2 = 28/2 = 14 cm
Answer:
C≈8.17cm
Step-by-step explanation:
C=2πr=2·π·1.3≈8.16814cm
Answer:
1.25 would be the leading coefficient
Step-by-step explanation:
Leading coefficients in scientific notation have to be more than 1, and less than 10. Therefore, 12.5 or 0.125 would not be correct answers as they do not fit the criteria. Only 1.25 would work as the leading coefficient.
