Answer:
31.483
Step-by-step explanation:
913/29=31.483
B
Because first “reduce” both sides of the top equation by the same to simplify it. See what both sides have in common.
They both have 3 long rectangles and 2 Sm. Squares.
That leaves, 2 long rectangles = 6 squares.
Which means that each long rectangle = 3 squares
Answer:
a) 8 subsets
b) 32 subsets
Step-by-step explanation:
The total number of subset of a set is known as the power of the set
Power of a set is expressed as;
P = 2^n
n is the number of element in the set
a) For a set containing 3 elements
n = 3
Power of the set = 2³
Power of the set is 8
This means that the set contains 8 different subsets
b) Cardinality of a set is the total number of element in the set
If the cardinal number of a set is 5, this means that the set contains 5elements
Hence the power of the set will be;
P = 2^5
P = 32
Hence the total number of subset for set whose cardinal number is 5 is 32
Answer:

Step-by-step explanation:
The <u>total area</u> of the circle is given by:

where
is a constant 
and
is the radius: 
Thus the total area of this circle is:

We want only the area of the arc that measures 50°. For this we must remember that the arc of the total circle is 360°.
Thus, we want 50° out of the 360° degrees in the circle. For this, we divide the total area by 360 and then we multiply by 50:

the area of the sector to the nearest tenth is
