Answer:
$920
Step-by-step explanation:
The amounts added are the arithmetic sequence ...
1, 2, 3, ... 40
The average term of this sequence is (1 +40)/2 = 20.5. The sum of the terms of this sequence is the number of terms (40) multiplied by the average term (20.5). That product is ...
40·20.5 = 820
Chu-Li will have added $820 to her bank in 40 weeks, so the total there is ...
$100 +820 = $920 . . . amount Chu-Li will have 40 weeks from now
I think $6.75 for 15 juice boxes is better because, each juice box is 0.45.
While $5.50 for 11 juice boxes is 0.50.
And if we were to add 0.50 enough times to make 15 juice boxes it would equal 7.50
RIP OFFFFFFF
THE SECOND ONE IS A WAY BETTER OF A DEAL
Answer:
Step-by-step explanation:
Money spent on rent =1/3 of $576= 1/3×576= $192
Money spent on food = 1/4 of 576 = 1/4×576 =$144
Money left = 576-(192+144)=
=576-336= $240
Unless otherwise specified we usually assume the dilation is about the origin. That is you can tell the scale factor by the way the distance to the origin changes.
Point C, for example, is 6 units from the origin. Its image, C' is 4 units from the origin. Then the scale factor image/original is 4/6 = 2/3.
Your green question mark gets filled with 3 to make the fraction 2/3.
_____
To find the translation, pick any point on A'B'C' and find the corresponding point A'', B'', or C''. Count the squares you have to go left to get from A' to A'', for example. That will be 5 to the left. Similarly, count the squares you have to go down to get from A' to A''. That will be 4 down.
