Answer:
(1,5) is not a solution to the system of equations
Step-by-step explanation:
To find the point (1, 5) is a solution to the system of equations.
We look at the intersection of both graphs given
Both graphs intersects at (0,2)
Intersection of two graphs is the solution of system of equations
Two graphs intersects at (0,2). so (0,2) is the solution of system of equations
(1,5) is not a solution to the system of equations
Answer: 73.55%
Step-by-step explanation:
p = (100-a) e^-b(0.07)
we have a = 20 and b =1.2
= (100-20) e^-(1.2)(0.07)
= 80(e^-0.084)
= 80(0.919431)
= 73.55%
For this priblem you'll have to find 7,5% of 110. To find the equivalent amount to the given percentage of a number, you multiply the percentage by the number, and then divide that amount by 100:
7,5 * 110 / 100 =
825 / 100 =
$8,25

Answer:
of the burgers were well done
Step-by-step explanation:
Firstly, we are told that a total of 50 burgers were served at Kayla's Burgers, this represents the
.
In additon, we are told 15 of that burgers were cooked well done and we need to know which percentage they represent. This can be calculated by the Rule of Three as follows:
-----![100 \%](https://tex.z-dn.net/?f=100%20%5C%25)
-----![X](https://tex.z-dn.net/?f=X)
Then:
![X=\frac{(15 burgers)(100 \%)}{50 burgers}](https://tex.z-dn.net/?f=X%3D%5Cfrac%7B%2815%20burgers%29%28100%20%5C%25%29%7D%7B50%20burgers%7D)
This means that
of the burgers were well done
