Answer:
8 inches = 120 miles
Step-by-step explanation:
If 2 inches is equivalent to 30 miles, then divide 120 by 30 then times the answer by two.
120 / 30 = 4
4 x 2 = 8
8 inches = 120 miles
To check;
30 x 4 = 120
8 / 2 = 4
Hope this helps!!!
7/4*1/5= 7/20
always remember that in math the word "of" always means you need to multiply.
so the answer is 7/20
Answer:
0.000071
Step-by-step explanation:
The given number that is given in scientific notation is, ............(1)
We need to write this number in standard notation. A number can be written in scientific notation as :
..........(2)
In standard notation,
So, is equivalent to . Hence, the correct option is (d)
Based on the given data, the following formula will be useful;
Area of the base, A = pi*r^2
Lateral Area, A(l) = pi*r*sqrt of h^2 + r^2
Surface Area, A(s) = pi*r*(r+sqrt of h^2 + r^2)
Based on the given area of the base, the radius can be calculated and is equal to 3.9088 in. Based on the given lateral area, the h or the lateral edge can be calculated and is equal to 7.8785 in. Given all the information needed, and directly substituting to the above formula for surface area, SA is equal to 156 in^2 (option D)
