Answer:
Step-by-step explanation:
In the diagram below:
First, we determine the value of
To determine the value of side a, we apply the Sine rule
Similarly, to determine the value of side b, we apply the Sine rule
Therefore:
Angles on one side of a straight line will always add to 180°.
This is the concept of algebra, given that the room is 150 sq. feet, the dimensions of the room can be found as follows;
Suppose the room is a perfect square, the length=width= x ft
therefore the are will be:
area=length*width
=x*x=x^2 sq. ft
hence;
x^2=150
getting the square root of both sides we get:
sqrt x^2=sqrt150
x=sqrt150
x=12.248 ft
x=12 ft (to the nearest feet)
Answer:
Total 1352 different arrangements can be formed.
Step-by-step explanation:
Total number of letters is 26 (a to z).
We need to find the arrangements of 3 letters
It is given that the first letter must be w or k and repetition of letters are allowed.
Since first letter can be w or k, therefore the possibilities for first letter is 2.
Repetition of letters are allowed and any letter can be formed in place of second and third letter.
So, the possibilities for second letter is 26 and possibilities for third letter is 26.
Total possibilities of arrangements of 3 letters is
Therefore total 1352 different arrangements can be formed.
Answer:
Number of pizza deliver on Saturday = 14 pizza
Step-by-step explanation:
Given:
Number of delivery day (Friday, Saturday) = 2
Number of pizza deliver on Friday = 8
Average of delivery (Mean) = 11 pizza
Find:
Number of pizza deliver on Saturday
Computation:
Mean = Sum of pizza / Number of delivery day
11 = [8 + Number of pizza deliver on Saturday] / 2
22 = 8 + Number of pizza deliver on Saturday
Number of pizza deliver on Saturday = 22 - 8
Number of pizza deliver on Saturday = 14 pizza
