1st week 10 5
2nd week 20 10
3rd week 30 20
4th week 40 40
<span>
A) Amanda's method is linear because the number of minutes increased by an equal number every week.</span>
common difference is 10.
1st week 0 + 10 = 10
2nd week 10 + 10 = 20
3rd week 20 + 10 = 30
4th week 30 + 10 = 40
Billy's method is exponential:
5(2)^x
1st week 5(2⁰) = 5(1) = 5
2nd week 5(2¹) = 5(2) = 10
3rd week 5(2²) = 5(4) = 20
4th week 5(2³) = 5(8) = 40
A
The volume (V) of a pyramid is found using the formula
V =
× area of base × height(h)
area of base = 9² = 81 ← area of a square, hence
324 =
× 81 × h = 27h ( divide both sides by 27 )
h =
= 12 → A
Question 7: $3945
78,900÷100×5= 3,945
or 789,00×0.05= $3,945
Question 8: I think it may be $675.46 ( but I'm not sure)
$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12
$1010÷12= $84.20
also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.
$938÷12=$78.20
and in order to find out her combined monthly payment we need to add them all together
$513.12+$84.16+$78.16= $675.46
Question 9: is False
Question 10: I don't know
Hope this helps
Answer:
I believe it is C. The square root of 47
Step-by-step explanation:
Because the distance from her house to the pool is about 6 and the square root of 47 is 6.8
