Answer:
Option d is correct.
Equation : P=7n+20.
Explanation;
Given the perimeter of each figure is;
Perimeter of triangle is equal to the sum of all the sides of a triangle.
Perimeter of 1 triangle is 21
Perimeter of 2 triangle is 34 and
Perimeter of 3 triangle is 41
Let n be the number of figure and P be the perimeter of the figure;
the only equation which satisfy the given perimeter is;
![P=7n+20](https://tex.z-dn.net/?f=P%3D7n%2B20)
Check:
for n =1 which means 1 triangle then;
![P =7n+20 = 7 \cdot 1 +20 = 7+20 = 27](https://tex.z-dn.net/?f=P%20%3D7n%2B20%20%3D%207%20%5Ccdot%201%20%2B20%20%3D%207%2B20%20%3D%2027)
for n = 2 , [ i.e 2 triangle]
![P =7n+20 = 7 \cdot 2 +20 = 14+20 = 34](https://tex.z-dn.net/?f=P%20%3D7n%2B20%20%3D%207%20%5Ccdot%202%20%2B20%20%3D%2014%2B20%20%3D%2034)
and for n =3 [i.e, 3 triangles]
![P =7n+20 = 7 \cdot 3 +20 = 21+20 = 41](https://tex.z-dn.net/?f=P%20%3D7n%2B20%20%3D%207%20%5Ccdot%203%20%2B20%20%3D%2021%2B20%20%3D%2041)
Therefore, the equation P =7n+20 relates the number of triangles in the figure(n) to the perimeter of the figure(P).
.Answer:
The answer is below
Step-by-step explanation:
The patient loses 1 kg every week for 5 weeks.
1 kg = 2.2 lbs
Therefore the patient loses 2.2 lbs every week for 5 weeks.
a) The weight of the patient after 5 weeks = 245 lbs. - (5 weeks)(2.2 lbs per week)
The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.
b) The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.
1 kg = 2.2 lbs.
234 lbs. = 234 lbs. * 1 kg per 2.2 lbs. = 106.36 kg
Answer:
B. The flow rate of the large tank is –10 gal/min, and the flow rate of the small tank is 10 gal/min.

Answer:
Total cost = $111
Step-by-step explanation:
Given:
Total number of oak tree = 3
Total number of elm tree = 1
Each oak tree cost = $23
Each elm tree cost = $42
Find:
Total cost
Computation:
Total cost = 3[Each oak tree cost] + 1[Each elm tree cost]
Total cost = 3[23] + 1[42]
Total cost = 69 + 42
Total cost = $111
Try this: (29.99 units/day)(1000 days) = 29990 units.
