Answer:
The answer for this is 5!
Step-by-step explanation:
<em>First, the two bottom angles are similar so add 52 and 52. After that subtract what you found from 180. A triangle has a total of 180 degrees in all three of their angles. </em>
<em>You will get 76. Then subtract 6 from that and divide by 14. There is your answer :)</em>
Answer:
11/21
Step-by-step explanation:
34 and the 10 numbers in the 40s have at least one 4. If you include 30 and 50 in the range you're choosing from, then 11 out of the 21 numbers have at least one 4.
A randomly chosen integer from [30, 50] has a probability of 11/21 of having at least one 4.
Answer:
The volume of the hemisphere is 496741.6 m³
Step-by-step explanation:
The volume of an sphere is given by:
In which and r is the radius.
An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So
In this question:
. So
The volume of the hemisphere is 496741.6 m³
Answer:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:
Step-by-step explanation:
z=xi+yj
x=-1.2=r cosθ (say)
y=-1.6=r sinθ(say)
square and add
r²cos²θ+r² sin ² θ=(-1.2)²+(-1.6)²=1.44+2.56=4
r²=4
r=2
divide
tanθ=y/x=-1.6/(-1.2)=16/12=4/3
θ=tan ^{-1}(4/3)≈53.13°
so polar coordinates are (2,53.13°)
