Answer:
The length is 48
The width is 20
Step-by-step explanation:
When 2 rectangles (figures) are similar, the ratio of corresponding sides are equal.
This rectangle is 5 by 12, so the shorter side (corresponding to 5) to the longer side (corresponding to 12) would be the same ratio, 5:12.
Let shorter side be s, and
longer side be l
It says, long side is 8 greater than twice short, we can write this as:
In similar rectangles, we have said the corresponding sides' ratio are equal, so we could write:
Now, we replace the new found expression for "l" onto this and cross multiply and solve for s first:
So the shorter side is 20. and hence the longer side would be:
l = 2s + 8
l = 2(20) + 8
l = 40 + 8
l = 48
The longer side is 48.
The length is 48
The width is 20
Answer:
Option A , C ,D
Step-by-step explanation:
A nonrefundable deposit required for the day-long program = $50
Charge per person = $4.50
Let us suppose the number of students is s
So, Charge for s students = $4.50s
Let c denotes the total cost
So, total cost :
So, Option A is correct : The linear model is f(s) = 4.5s + 50.
Total cost :
We are given that total students are 24
Substitute s = 0
So,
Substitute s = 24
So, Option C and D is also correct.
C. The domain is {x| 0 ≤ x ≤ 24}
D .The range is {y| 50 ≤ y ≤ 158}
Refer the attached figure
The graph is discrete .
So, Option E is incorrect.
