I'm pretty sure that the answer is 12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495
Hope this helps
Answer:
nope it would be B (1)
Step-by-step explanation:
Using an exponential equation, supposing a rate of 5%, it is found that it will take about 2.9 years for Emma's balance to reach $450.
An increasing exponential function is modeled by:
In which:
A(0) is the initial value.
r is the growth rate, as a decimal.
In this problem:
Her initial balance is of $300, hence . A(0)=300
The growth rate is of 15%, hence R =0.15
Then,
It will reach $450 after t years, for which A(t) = 450, hence:
It will take about 2.9 years for Emma's balance to reach $450

Solve the system of equations by graphing
Remember that the solution of the system is the intersection point both graphs
Using a graphing tool
The intersection point is (2.333,-1.667)
see the attached figure
therefore
The solution is
8 out of 40 fifth graders went to see the lab animal presentation. This can be written as this expression:
Find the greatest common factor of 8 and 40:
Factors of 8: 1, 2, 4, 8
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Therefore the greatest common factor is 8. Divide both the numerator and the denominator by 8.
Therefore the fractional part is
.
To get the percentage, you need to get the denominator to a value of 100.
To do so, you need to find the value to multiply both the numerator and denominator by to achieve this.
To get this value, you can divide 100 by the denominator of the fractional value.
Then you can multiply both the numerator and denominator by 20:
From here, the numerator will state the percentage:
