Answer:
Having 2 meters and 25 meters legs and 3 meters and 30 meters legs.
Step-by-step explanation:
Priya thinks that an angle of elevation of 7 Degrees or less will be safe for a learner of bike riding.
Now, a 7-degree elevation angle in a right triangle will have a 3 : 25 ratio of its legs.
Therefore, the list of 2 right triangles that would be safe for a new rider will be having 2 meters and 25 meters legs and 3 meters and 30 meters legs.
I both cases the angle of elevation will be less than 7 degrees. (Answer)
Answer:
Option A - 
Step-by-step explanation:
Given : For the sequence 
To find : Identify the values of following?
Solution :
The nth term of the sequence is
Substitute n=0,1,2 and 3
When n=0,
When n=1,
When n=2,
When n=3,
Therefore, The value is
So, Option A is correct.
The system of equations is
n + d = 27
n + 5d = 55
Step-by-step explanation:
The given is:
- Kiran has 27 nickels and quarters in his pocket
- They worth a total of $2.75
- We need to write a system of equations to represent the relationships between the number of nickels n, the number of quarters d, and the dollar amount in this situation
∵ The number of nickles is n
∵ The number of quarters is d
∵ There are 27 nickles and quarters
∴ n + d = 27 ⇒ (1)
∵ 1 nickel = 5 cents
∵ 1 quarter = 25 cents
- Multiply n by 5 and d by 25 to find their value
∴ They worth = 5n + 25d
∵ They worth a total of $2.75
- Chang the dollar to cent
∵ 1 dollar = 100 cents
∴ $2.75 = 2.75 × 100 = 275 cents
- Equate their value by 275
∴ 5n + 25d = 275
- Simplify it by divide each term by 5
∴ n + 5d = 55 ⇒ (2)
The system of equations is
n + d = 27
n + 5d = 55
