Find the length of one side of a square inscribed in a circle that has a radius of 4 cm.
Answers
The length of one side of a square = 8 cm
To find out the length of one side of a square that is inscribed in a circle that has a radius of 4 cm:
Since the square is inscribed in the circle, a diagonal
of the square is a diameter of the circle.
The diameter of the circle = 2 x radius = 8 cm .
The diagonal of the square = 8 cm.
The diagonal of a square is (length of a side) x (√8).
Side x √8 = 2√2 cm
Divide each side by √2:
Side = 8 cm / √2 = 8 √2 / √2 = 8 cm.
Hence the answer is the length of one side of a square = 8 cm

Answers
The approximate surface area of an AA battery would be = 5,583 mm^2. That is option A.
What is an AA battery?An AA battery is defined as the type of battery that is used to supply chemical energy to electronic gadgets.
The AA battery has the shape of a cylinder and the formula for the surface area of cylinder:
h = 49.5mm
r = 14mm
π = 3.14
A=2πrh+2πr²
A = (2×3.14 ×14×49.5)+ (2× 3.14×14²)
A = 4,352.04 + 1,230.88
A = 5582.92
Therefore the surface area of the AA battery is approximately 5,583 mm^2.

Answers
The given speed in kilometers per sec to miles per hour is 51449.534 mph.
Given that, the Oyo Empire if they are traveling 23 kilometers per sec.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Now, the conversion of kilometers per sec to miles per hour is as follows:
To convert a kilometer per second measurement to a mile per hour measurement, divide the speed by the conversion ratio.
Thus, mph = km/s ÷ 0.00044704
Now, 23/0.00044704
= 51449.534 miles per hour
Hence, the given speed in kilometers per sec to miles per hour is 51449.534 mph.

Part B:Cindy sells 24 slices of blueberry pie and 15 slices of cherry pie. The next day, she sold 26 slices of blueberry pie and 17 slices of cherry pie. What was her total profit?
Answers
A) 3.5a +3.5b ≥ 128.09 B) Total profit: $158.91
1) Gathering the data
$65.25 ingredients for blueberry pies
$62.84 cherry pie
Each slice
3.50
A) Since Cindy's profit relies on her sales we can write
b = slices of blueberry
c = cherry pie slices
3.50b +3.50a ≥ 65.25+62.84
3.5a +3.5b ≥ 128.09
B) Gathering those data and adding the number of slices that were sold:
1st day
b= 24
a =15
2nd day
b=26
a=17
Plug into that:
Profit: 3.5(15+17) + 3.5(24+26)
P =287
$287 was the total revenue
Cherry pie cost of production 62.84
3.5(15+17)=112
Profit = 112 -62.84
Profit = $49.16
Blueberry cost of production: $65.25
3.5(24+26) =175
175 - 65.25 =109.75
Profit $ 109.75
Total profit: $158.91

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.
Given ,
The automotive manufacturer produces 12 more automobiles than trucks each day.
T is the input and c is the output in this connection. Therefore, by adding 12 to t, you may calculate c.
Write this connection as a function.
c = t + 12
To determine the value of c, replace t in the function with 1 instead.
c = t+12

work is done on the toy car?
Answers
The work is done on the toy car is 164.4 J .
How to calculate work done?We are aware that the definition of work is the multiplication of the magnitude of the displacement (d) and the component of the force acting in the displacement direction.
When an object moves over a distance while being applied with force, the work is considered to have been completed.
Three categories can be used to classify the type of labor performed. Positive work, negative work, and zero work are the three types. The angle between force and displacement determines the kind of work that is done. Positive work is defined as any work that causes an object to move in the direction of the applied force.
Given ,
Work = force * distance
Force = 5.2 N
Distance = 32 m
So ,
Work = 5.2 * 32

Given:
The total no of Accord sold = The total no of Camry sold - 81000,

The total no of Accord sold + The total no of Camry sold = 865000
The total no of Camry sold - 81000+The total no of Camry sold =865000,
The total no of Camry sold = 865000+81000 / 2
The total no of Camry sold = 473000, and
