To find out the total time Jake and Kyile spent working in their project we have to make a multiplication of the time spent and the days they did it:
jake = (3/4)*2 = 6/4 = 3/2
so Jake spent 3/2 hours working in his project, that is 1.5 hours
kyile = (1/4)*6 = 6/4 = 3/2
Therefore they worked the same amount of hours!
Because the balls or spheres are tightly packed in a cube, their radius is approximately equal to 2 ft. The volume of a sphere is calculated through the equation,
V = 4/3πr³
Substituting the known radius,
V = 4/3π(2 ft)³
V = 33.51 ft³
The 9 spheres will have a total volume of 301/59 ft³ which is also equal to 521152.52 in³.
Answer:
D.) 9√2
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 8^2 = √226^2
x^2 + 64 = 226
x^2 = 226 - 64
x^2 = 162
√x^2 = √162
√162 = √81 • √2
√81 = 9
√2 = √2
9√2
Answer=B 4.8
We have a right triangle in the drawing so for the altitude we can use the pythagorean theorem. It's as follows...
a²+b²=c² (where a and b are the side lengths and c is the hypothenuse)
Lets input in the data that we have.
11²+b²=12²
simplify
121+b²=144
subtract 121 from both sides
b²=23
To solve for the missing side/altitude we just need to find the square root of 23
b=√23
b=4.79 or 4.8
Answer=B
P(7) = 1/8 = 0.125 out of 1
