Answer:
5 × 3=15 and 5+5+5=15 that's all
Answer:
6x = 120
Step-by-step explanation:
Let the number be " x ".
The product of 6 and a number,
6 * x = 6x
The product of 6 and a number is 120,
6x = 120
Therefore,
the algebraic form is 6x = 120.
Answer:
option A
{1, 2, 4, 7, 9}
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable. Mostly it is 'x' values.
In the figure the tail of arrow represent values of domain and head of arrow represent values of range.
So,
{1, 2, 4, 7, 9} is the domain of G(x) and {3, 5, 8} is the range
Answer:
The ratio of the small sphere’s area to that of the big one is 25:64
Step-by-step explanation:
The area of a sphere can be calculated using the formula:
A = 4 π r^2
Now, since their radii are if the ratio 5:8, we can say that the radius of the small sphere is 5 while that of the big sphere is 8
For the small sphere, the value of the area will be 4 * π * 5^2 = 100 π unit
For the big sphere, the value of the area will be 4 * π * 8^2 = 256 π unit
The ratio of the smaller sphere to the larger sphere is;
100 π : 256 π
Divide through by 4
25: 64
Divide 26 by 6 to get 4.33. Divide 60 by 3 to get 20.
It will take approximately 4 hours and 20 minutes to run the marathon.
