Answer: D. n + q = 20
5n + 25q = 300
Let n indicate the total number of nickels you own.
Let q signify the quarters you possess.
Given that you have 20 coins, this leads to the equation n + q = 20.
The overall value of the coins equals $3. Since a quarter is worth $0.25 and a nickel is valued at $0.05, the following equation results:
0.05n + 0.25q = 3.
After multiplying both sides by 100, you get 5n + 25q = 300.
The right choice is D. n + q = 20
5n + 25q = 300
The statue stands at a height of 21.4 feet. To explain in detail, we know that a person positioned 50 ft away from the statue looks up at an elevation angle of 16 degrees towards the top and looks down at an angle of depression of 8 degrees to see the base. To visualize, we can draw a diagram. For triangle ABF, we have that FC equals 50. We will employ trigonometric formulas to calculate x. In triangle DEF, similarly, we will apply trigonometric formulas and find that the statue's height equals x+y. Thus, the total height of the statue is found.
Y - 52 = (580 - 52)/(8 - 2) (x - 2)
y - 52 = 528/6 (x - 2) = 88(x - 2)
y = 88x - 176 + 52
y = 88x - 124
Answer: Mrs Bell
Step-by-step explanation:
According to the information provided, Mrs. Bell's house has an interest rate of 4.175% or 0.04175, while Mr. Bentley's house has an interest rate of 4.25% or 0.0425.
Thus, Mrs. Bell benefits from the lower interest rate, as 4.25% exceeds her rate of 4.175%
Response:
15
Step-by-step explanation:
To determine the number of classes, subtract 10 from 146 which leaves you with 136. Dividing 136 by 9 results in approximately 15.1 repeating, but since classes cannot be a fraction, the answer rounds down to 15.
