Answer:
I'm pretty sure A but let me know if I'm wrong
8 * 684 = 5472
it is in between 5471 and 5473
Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)
after 4 weeks:
.3*4= 1.2 saved
then it is doubled
1.2*2 = 2.40
8 weeks
he will have saved for 4 more weeks ( week 5 6 7 8)
4 * .3 = 1.2 saved
2.4 + 1.2 = 3.6 saved
then it is doubled
3.6 * 2 =7.20
he will have saved for 4 more weeks ( week 9, 10, 11, 12)
4 * .3 = 1.2 saved
7.2+ 1.20=8.40
then it is doubled
8.4*2 = 16.8
He will have 16.80 after 12 weeks
First, we know that the equation for permeter of a circle is C=2*pi*4 or C=2*3.14*r if you are using 3.14 for pi. Since this is a semicircle, we simply divide this equation by 2 and plug in our radius (radius id 6 because 12/2 =6)
So we are using C=3.14*r
C=3.14*6
So the perimeter equals 18.84 so A
Hope this helps!
