What is a diameter?The diameter of a circle or sphere is the length of a straight line that passes through the center of a body or figure, notably a circle or sphere.
The diameter of the circle is 11 4/5 ft, which can be written as:
11 4/5 ft = 11 + 4/5 ft = (11 x 5)/5 + 4/5 ft = 55/5 + 4/5 ft = 59/5 ft
The formula to calculate the radius of a circle using the diameter is:
radius = diameter/2
So, the radius of the circle is:
radius = (59/5)/2 = 59/10 ft
Now, we can use the given expression to represent the radius in terms of Z:
radius = Z + 3.6
Substituting the value of the radius, we get:
59/10 = Z + 3.6
Subtracting 3.6 from both sides, we get:
59/10 - 3.6 = Z
Multiplying both sides by 10, we get:
Z = 59/10 - 36/10
Z = 23/10
Therefore, Z = 2 3/10.

If the volume of cube is 8a3 + b3 + 12a2b + 6ab2. What is the
measure of the side of the cube?
Answer:
2a + b
Step-by-step explanation:
volume = 8a³ + b³ + 12a²b + 6ab² = (2a + b)³
volume = ( Side of the cube )³
( Side of the cube )³ = (2a + b)³
Side of the cube = 2a + b

Can u solve it?
Find x,y,v and u.
Explanation:
Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.
the optimal way is to do it with Cramer's rule.
First, find the determinant and then find the determinant x, y, v, u.
Afterward, simply divide the determinant of variables by the usual determinant.
eg. [tex]\frac{Dx_{} }{D}[/tex] and etc.
I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

Step-by-step explanation:
a function is defined by the equation f(1/2)=2X-5
Answer:
The value of f(-1) in the given equation is -10.
Step-by-step explanation:
When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.
f(-1) = -3(-1)² + 2(-1) - 5
Simplify the exponent on -1.
f(-1) = -3(1) + 2(-1) - 5
Multiply -3 by 1.
f(-1) = -3 + 2(-1) - 5
Multiply 2 by -1.
f(-1) = -3 - 2 - 5
Subtract 2 from -3.
f(-1) = -5 - 5
Subtract 5 from -5.
f(-1) = -10

Answer:
exactly 135 grandparents
Step-by-step explanation:
Here, it asks us for how many grandparents spend less than two hours online, which is 54% as that is what the sample result says. Now, you must what 54% of 250 is to find the number of grandparents who spend less than 2 hours. To do this, you make 54% a decimal and multiply it with 250. You do 0.54 x 250, which gives you exactly 135 grandparents who spend less than two hours online.
