8.4 x 10^12 / 4.2 x 10^6 = 2 x 10^6
For A it is 6240 / 20% for B it is 6240 x 15%
Answer:
Zack earned £125, Jack earned £75, and Sasha earned £50
Step-by-step explanation:
Considering the number of leaflets delivered
Zack 50%, Jack 30% and Sasha 20%
Total delivered = 50 + 30 + 20 = 100%
If they earn £250 on the 100% delivery, then each will have as shown below
Zack = (50/100)*250
= 5*25
= £125
Jack = (30/100)*250
= 3*25
= £75
Sasha = (20/100)*250
=2*25
= £50
Answer:
Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3
