Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she
1 answer:
Answer:
Number of dimes = 34
Number of nickels = 13
Step-by-step explanation:
Total number of coins = 47
Coins are in the form of nickels and dimes.
Value of a nickel = 5 cents
Value of a dime = 10 cents
Total value of coins = $4.05 or 405 cents
To find:
Number of nickels and dimes?
Solution:
Let number of nickels =
Money value of nickels = 5
Let number of dimes =
Money value of dimes = 10
Total value of coins =
This value is given as equal as 405.
As per question statement, the equations can be written as:
Multiplying equation (2) with 5 and subtracting from equation (1):
Number of dimes = 34
Number of nickels = 47 - 34 = 13

Answer:
Option (D)
Step-by-step explanation:
In the picture attached,
An obtuse angle triangle ABC has been given.
By applying Sine rule in the triangle,
Since, m∠A + m∠B + m∠C = 180°
45° + 110° + m∠C = 180°
m∠C = 180°- 155° = 25°
b =
b = 15.56
b ≈ 15.56
a =
a = 11.712
a = 11.71
Therefore, Option (D) will be the answer.
1. Each term in this polynomial has a common factor of :
2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.
3. You can use the same approach as in (2), or recall that :
4. Recall that a difference of squares can be factored as . So
