Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
Answer:
scale factor = 
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original
scale factor =
=
= 
I think the answer is B? They didn't say whether point P is in the centre of the circle, so the answer could also actually be D. But assuming that P is the centre point of the circle, the answer should be B.
AP (7mm) > Radius of circle p (6mm)
meaning that the line should extend out of the circle from the centre of it and thus produce one intersection.
As for the rest of the line, BP,
BP (3mm) < Radius of circle p (6mm)
meaning that if the distance of point P to point B is shorter than the distance of point p from the line of the circle (this distance being the radius), it should not make another intersection.
Therefore, there is only 1 intersection and the answer should be B (if point P is the middle of circle p)
