What is the perimeter of a square with an area of 256 cm^2
Answer:
16cm
Step-by-step explanation:
The area of a square is calculated by perimeter * perimeter. 256 is made of 16*16
Answer:
you know that the Area of a square is calculated as S^2 or SxS
to find the side length just do square root of 256
wich is 16 cm
multiply by 4 and the perimeter is 16*4= 64

solve the enquality 2x+1>11
Step-by-step explanation:
2x+1>11 1 is positive integers so it have to be cancelled by negative integer 1
2x>11-1
2x>10 two will be cancelled by two to get x
then we divide 2 from 10
x>5 this means x is greater than 5
{x=6,7,8,...}
Convert the angle 2π/3 radians to degrees.
Answer:
2π/3 radians is equal to 120°.
Step-by-step explanation:
In this problem, we need to convert the angle 2π/3 radians to degrees.
The relation radian and degree is given by :
[tex]D=\dfrac{180}{\pi}\times R[/tex]
Substitute all the values,
[tex]D=\dfrac{180}{\pi}\times \dfrac{2\pi }{3}\\\\D=120^{\circ}[/tex]
So, 2π/3 radians is equal to 120°.

3. A taxi cab company charges $3.00 for 1 minute and $5.50 for 6 minutes.
a) Calculate the slope. What does it mean according to the question?
b) Calculate the y-intercept. What does it mean according to the question?
c) How much would it cost for a 30-minute cab ride?
d) How far could you travel for $50?
Answer:
a) 1/2
b)2.5
c)17.5
Step-by-step explanation:
The question gives you two points on the line. From this, you can calculate the slope. Since slope is m=[tex]y_2-y_1/x_2-x_1[/tex], the work for question a is as follows:
m= 5.5-3/6-1
m=1/2 or 0.5
Now, you can use the information given to calculate the y-intercept. Use any of the two points to fill in x and y, and use the slope you just calculated to fill in for m. Fill in the equation and use algebra to isolate the variable and solve for b.
y=mx+b
3=0.5(1)+b
3-0.5=b+0.5-0.5
2.5=b
Finally, plug in all the numbers to find the answer for question c.
y=0.5x+2.5
y=0.5(30)+2.5
y=17.5

Step-by-step explanation:
Given the table:
Month f(x) = Number of imports g(x) = Number of exports
January (1) 3 1
February (2) 4 3
March (3) 5 5
April (4) 6 7
From the table, it is clear that:
Number of imports = number of month + 2
so
also
Number of exports = 2(number of month) + 1
so
Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.
If we compare it with the slope-intercept form of the line
Then,
slope = m = 1
y-intercept = 2
Also number of exports equals is also a linear function.
i.e.
Here,
slope = m = 2
y-intercept = -1
If there is some point that is equal in both the function then it can be said that they are intersecting.

Answer:
Step-by-step explanation:
the area of the squared is 5 * 5 = 25
the area of the triangle is 1/2*base*height = 1/2*2*5= 5
the area of the circle is [tex]\pi[/tex][tex]r^{2}[/tex] = [tex]\pi[/tex][tex]2.5^{2}[/tex] = 19.625
now add the pieces up for the total
25+5+19.625 = 49.625 [tex]in^{2}[/tex]
:)
First, find the area of the semi-circle.
A= pi*radius squared
Find your radius. The diameter is 5, half of that is 2.5
Input into the formula
A= pi*2.5^2
=3.14*6.25
=19.625 in^2
You can round that to about 19.6 inches.
Find the area of the square
A=s^2
= 5^2
= 25 in^2
Find the area of the triangle.
A= b*h/2
= 2*5/2
= 10/2
= 5 in^2
Add it all up.
19.6+ 25 + 5= 49.6
∴ 49.6 in²

What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
From the graph:
The midline is the horizontal line about which the graph of a function oscillates
y = -2
The amplitude is the half vertical distance the function travels around the midline.
Amplitude = 1.5
The period: the distance traveled to complete the one rotation:
Period = 4π

Answer:

Step-by-step explanation:
5+2=7
3x5=15
5-5=0
Answer:
A. 20 - x = 5 X = 15
B. x + 2 = 7 X = 5
C. 3x = 15 X = 5
D. 5x = 15 X = 3
E. x - 5 = 0 X = 5
Step-by-step explanation:
For A
Steps
20 - x = 5
subtract 20 from both sides.
20 - x - 20 = 5 - 20
Simplify
-x = -15
Divide both sides by negitive 1
-x/-1 = (-15)/ -1
Simplify
x = 15
For B
Steps
x + 2 = 7
subtract 2 from both sides.
x + 2 - 2 = 7 - 2
Simplify
x = 5
For C
Steps
3x = 15
Divide both sides by 3
3x/3 = 15/3
Simplify
x = 5
For D
Steps
5x = 15
Divide both sides by 5
5x/5 = 15/5
Simplify
X = 3
For E
Steps
x - 5 = 0
Add 5 to both sides
x - 5 + 5 = 0 + 5
Simplify
X = 5

Find the volume of a sphere with a diameter of 8cm
Answer:
V = 267.95
Step-by-step explanation:
Volume of a Sphere:
V = 4/3πr³
r = d/2
r = 4
Work:
V = 4/3πr³
V = 4/3(3.14)(4³)
V = 4/3(3.14)(64)
V = 267.95
Answer:
268.1 cm^3
Step-by-step explanation:
The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r)^3.
If the diameter of this sphere is 8 cm, then the radius is 4 cm, and r^3 = 64 cm^3. Thus, the volume is:
V = (4/3)(3.14)(64 cm^3) = 268.1 cm^3
