Answer:
1/5
Step-by-step explanation:
There are 10 marbles and two white marbles.
make a probability.
2/10
simplify= 1/5
So first make them inproper fractions
6 2/3 = 20/3
4 7/8 = 39/8
then you multiply them
20 * 39 = 780
3 * 8 = 24
12 can go into both numbers
780 <span>÷ 12 = 65
24 </span><span>÷ 2 = 2
the answer is 65/2 or if you want it simplified 32 1/2
Hope this helped you :)

Answer:
<em>a:b:c=8:12:15</em>
Step-by-step explanation:
<u>Combined Ratio</u>
We are given the ratios:
a:b=2:3
b:c=4:5
The combined ratio a:b:c will include all three variables in one single expression.
Before finding it, we must have a common number for the common variable (b). Since b is 3 in the first ratio and 4 in the second ratio, we must equate both by finding the LCM of 3 and 4=12, thus both ratios will be amplified as follows:
a:b=2:3=(2*4):(3*4)=8:12
b:c=4:5=(4*3):(5*3)=12:15
Now there is a common factor in both ratios, we can combine them removing the common factor:
a:b:c=8:12:15
You would have to multiply 3 1/3 and 4 and that is 13.33...
The exponential function that models this situation is:
Using the function, in 2050, she will have $37,453.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
For this problem, the parameters are:
A(0) = 10000, r = 0.045.
Hence the equation is:
2050 is 30 years after 2020, hence the amount is:
