Answer:
The volume of new sphere is 3.375 times greater than the volume of old sphere
Step-by-step explanation:
Let r be the radius of old sphere. This old sphere is dilated by a scale factor of 1.5 to create a new sphere, so the radius of new sphere is R=1.5r.
The volume of the sphere can be calculated using formula
Hence,
Answer:
44
Step-by-step explanation:
There are 4 quarters in a dollar.
"How many quarters are there in eleven (11) dollars?"
4 x 11 = 44
There are 44 quarters in eleven dollars.
2 meters were used in 10 masks
2meters/10masks= 0.2meters per mask
Answer:
29
Step-by-step explanation:
x+11÷8=5
5 × 8 = 40
40- 11 = 29
29 + 11 ÷ 8 =5
Given:
The equation of the curve is:
To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,
Differentiate the given equation with respect to x.
Now we need to find the value of this derivative at (2,7).
Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
