Answer:
c ≈ 5.5 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 2.4² + 4.9² = 5.76 + 24.01 = 29.77 ( take square root of both sides )
c = ≈ 5.5 cm ( to the nearest tenth )
Answer:
There are 6 green beads there.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of green beads
y is the number of yellow beads
The ratio of green beads to yellow beads in a bracelet is three to four.
This means that
So
The total number of beads is 14.
This means that
How many green beads are there ?
This is x.
However
So
Using multiplying by the gcm(3)
There are 6 green beads there.
Answer:
The volume of solid is 268.08 inches cube.
Step-by-step explanation:
The solid spherical ball has height 8 inches that means the diameter of the sphere is 8 inches. So, the radius will be the half of diameter. Thus, radius is 4 inches.
Now use below formula to find the volume of solid sphere.
Therefore, the volume of solid is 268.08 inches cube.
Answer: Your answer is B.840
Step-by-step explanation:
