Answer:
A) 8cm
B) 12cm
Step-by-step explanation:
A) Perimeter = 4 × L
where L is the length of the sides
32 = 4 × L
32/4 = L
L = 8cm
B) Area = L^2
144 = L^2
L = square root of 144
L = 12cm
a)
The length of each side is 8 cm.
d)
The length of each side is 12 m.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
The perimeter of the square = 32 cm
Area of the square = 144 m²
Now,
Perimeter = 32 cm
4 Side = 32 cm
Side = 32 /4
Side = 8 cm
Area = 144 m²
Side² = 144
Side = 12 m
Thus,
The length of the side is 8 cm.
The length of the side is 12 m.

2x - 1y = -9
y = - 5 - 5x
Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30

John was 40" tall in 2008 and 46" tall in 2010. Dave was 53" tall in 2003 and 70" tall in 2007. Who is growing at
a faster rate? If each person keeps growing at the same rate, how tall can we expect each to be in 2011? Is this
a reasonable expectation?
Answer:
John is growing at a faster rate.
Step-by-step explanation:
John grew 6 inches in 2 years, while Dave grew 7 inches in 4 years. We can expect John to grow another 3 inches by 2011, making John 49 inches tall in 2011. We can expect Dave to grow about another 7 inches by 2011, since another 4 years has passed. This seems reasonable enough...

GH bisects ∠FGI.
So, ∠HGI =∠FGH
6x - 17 = 5x - 8 {Add 17 to both sides}
6x = 5x - 8 + 17
6x = 5x + 9 {Subtract 5x form both sides}
6x - 5x = 9
a) x = 9
b) ∠FGH = 5* 9 - 8
= 45 - 8
∠FGH = 37
c) ∠HGI = 6*9 - 17
= 54 - 17
∠HGI = 37
d) ∠FGI = ∠FGH + ∠HGI
= 37 + 37
∠FGI = 74

Soccerball 12.05 recommended psi tolerance+3.55 Basketball 8.00 average recommended psi tolerance +0.5 volleyball 4.44 average recommended psi tolerance +0.18
Answer:
For Soccer ball:
x = | 12. 05 + 3.55 |
For basketball:
x = | 8.00 + 0.5 |
For volleyball:
x = | 4.44 + 0.18 |
Step-by-step explanation:
Given the following :
Let x = ball's actual air pressure
_________avg Recommended psi ___tolerance
Soccer ball____ 12. 05 ____________+3.55
Basketball _____8. 00_____________+0.5
Volleyball _____ 4.44 _____________ + 0.18
Actual air pressure = | average recommended psi + tolerance |
Hence ;
For Soccer ball:
x = | 12. 05 + 3.55 |
For basketball:
x = | 8.00 + 0.5 |
For volleyball:
x = | 4.44 + 0.18 |

how does cheese spoil?
Answer:
Microbiological spoilage of cheese is one of the important reasons that render the nutritious and tasty cheese not only inedible but also a potential source of infection. The spoilage may be due to bacteria or fungi. The defect due to contamination may arise from the surface of the cheese showing visual and organoleptic changes or it may be hidden internally.
Answer:
Cheese: It smells like sour milk.
If you spot mold on hard cheese, it's generally safe to cut off the moldy part and eat the rest, since the spores likely will not have spread throughout the cheese. Another sign that cheese has gone bad is a smell or taste of spoiled, sour milk.
In a group of 28 students, 12 study both Art and Biology.
12 study Biology but not Art.
4 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
