Answer:
If you're asking what the perimeter is:
C 32cm
If you're asking what the length of a side is:
A 8cm
Step-by-step explanation:
Area of a square is calculated by length x width.
And all four sides of a square are equal in length.
Area: 8cm×8cm=64cm2
Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm
Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.
√(64)=8
Answer:
a)
b) 0.476
c) 0.667
Step-by-step explanation:
We are given the following in the question:
Y = the number of forms required of the next applicant.
Y: 1, 2, 3, 4, 5, 6
The probability is given by:
a) Property of discrete probability distribution:
b) at most four forms are required
c) probability that between two and five forms (inclusive) are required
Answer. 17<18
The sum of 3x + 14 equals 17x.
The difference between 20 - 2x equals 18x.
Therefore the equation is not equal to each other.
Answer:
$25.66
Step-by-step explanation:
Given data
Total Bill before tax and tip= $27.30
Tax= 9%
Tip= 15%
Let us find the tax
=9/100*27.30
=0.09*27.30
=$2.457
Let us find the tip
=15/100*27.30
=0.15*27.30
=$4.095
Therefore his bill after tax and tip is
=27.30+2.457-4.095
=$25.66
Answer:
5.415m and 2.585m long
Step-by-step explanation:
For a right triangle
hyp^2 = opp^2 + adj^2 (Pythagoras theorem)
Given
hypotenuse = 6m
height(opposite) = h meters
Adjacent = (8-h)m
Substitute into the expression above;
6² = h²+(8-h)²
36 = h²+64-16h+h²
36 = 2h²-16h+64
2h²-16h+64-36 = 0
2h²-16h+28= 0
Divide through by 2
h²-8h+14 = 0
Using the general formula
h = 8±√8²-4(14)/2
h = 8±√64-56/2
h = 8±√8/2
h = 8±2.83/2
h = 8+2.83/2 and 8-2.83/2
h = 10.83/2 and 5.17/2
h = 5.415 and 2.585
hence the length of the height of the right triangle are 5.415m and 2.585m long
