Step-by-step explanation: I DID THE WORK. SIMPLE
Answer:
14 quarters and 28 nickels
Step-by-step explanation:
System of Equations where x = number of quarters and y = number of nickels
(1) equation with value of each coin
0.25(x)+0.05(y) = 4.90
(2) total number of coins
x + y = 42
Solve system of equations using either substitution or elimination
(elimination multiplying equation 2 by -0.5)
.25(x) + 0.05(y) = 4.90
-0.05(x) - 0.05(y) = 42 * (-0.05)
(3) Resulting equation
.20(x) = 2.8
x = 14
plug x into equation 2
14 + y = 42
y = 28
There are 14 quarters and 28 nickels in Mary's collection.
Answer:
2023 rabbits
Step-by-step explanation:
The exponential model consists of the following expression:
Where:
- Initial population.
- Increase rate.
- Time
- Current population.
The initial population and increase rate are, respectively:
![r = \sqrt[4]{\frac{17}{12} }](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B4%5D%7B%5Cfrac%7B17%7D%7B12%7D%20%7D)
The exponential model that predicts the population of rabbits is:
Lastly, the expected population for the year 1996 is:
Answer:
height: 125m; distance: 500m
Step-by-step explanation:
x = 250
f(x) = x − 0.002x2
f(x) = 250 − 0.002(250 )2
= 250 − 0.002(62,500)
= 250 − 125
= 125
250 times 2 = 500
