Ok so first I am assuming you ment 2 sevenths so 12 divided by 2 sevenths is 42. so the father is currently 42. so when she was 10 he was 40. since 10 is 4 times 40 that is the age we need. so 42 minus 40 is 2. therefore the answer is 2.
Answer:
To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation.
so the three terms a
3(1)-2=1
3(2)-2=6-2=4
3(3)-2=9-2=7
As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16
so 16 is the tenth term
Hope this helped!
Answer:
81π ft³
Step-by-step explanation:
If the diameter is 6 ft, the radius is 3 ft.
The volume is V = (area of base)(height).
Here, V = (π[3 ft]²)(9 ft) = 81π ft³
Answer:
10, 22, 48.4, 106.48, 234.256
Step-by-step explanation:
The first term is already given it is 10.
The second term is the first term times 2.2.
10×2.2=22
The second term is 22.
The third term is the second term times 2.2.
22×2.2=48.4
The third term is 48.4.
The fourth term is the third term times 2.2.
48.4×2.2=106.48
The fourth term is 106.48.
The fifth term is the fourth term times 2.2.
106.48×2.2=234.256
The fifth term is 234.256.
Ummm this confuses me a bit
