Explanation:
The area of a circle can be calculated as:
[tex]\text{Area}=\pi\times r^2[/tex]Where π is approximately 3.14 and r is the radius of the circle.
So, if we have a circle of radius equals 4 ft, the area will be equal to:
[tex]\begin{gathered} \text{Area = 3.14}\times(4ft)^2 \\ \text{Area = 3.14}\times16ft^2 \\ \text{Area}=50.24ft^2 \end{gathered}[/tex]Answer: A=πr^2

determine the number of solutions for:
10x-2y=-16
-5x=8-y
hurry
The equations 10x-2y=-16 and -5x=8-y have infinitely many solutions because the lines are the same.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
10x - 2y = -16
-5x = 8 - y
Or
-5x + y = 8
10/(-5) = -2/1 = -16/8
-2 = -2 = -2
The equations are the same which means the lines are coincident.
There will be infinitely many solutions.
Thus, the equations 10x-2y=-16 and -5x=8-y have infinitely many solutions because the lines are the same.

Fill in the next two terms in the pattern. Enter your answers in the boxes. 0.16, 0.35, 0.54
ANSWER
0.73, 0.92
EXPLANATION
We want to fill the next two terms in the pattern.
The pattern given is:
0.16, 0.35, 0.54
There is a common difference in this pattern (the difference between two successive terms).
To find this, let us subtract the first term from the second:
0.35 - 0.16 = 0.19
This is the same for the third term subtracting the second term:
0.54 - 0.35 = 0.19
Therefore, the next two terms can be gotten by adding 0.19:
0.54 + 0.19 = 0.73
0.73 + 0.19 = 0.92
The next two terms are 0.73 and 0.92.

Given the inequality 6x ≤ 18, determine the value of x.
S:{26}
S:{14}
S:{7}
S:{3}
The value of x in the given inequality 6x ≤ 18, is S:3 out of all the given options.
The correct answer is S:3.
To solve for x, we divide both sides of the inequality by 6. When dividing by a negative number, we flip the direction of the inequality sign. This gives us x ≤ 3.
Therefore, the possible values of x are 3, 2, 1, 0, and so on. The answer can not be 26, 14, or 7, because those values would make x greater than 3.
Here is the solution in steps:
6x ≤ 18
6x/6 ≤ 18/6 (divide both sides by 6)
x ≤ 3
Therefore, the value of x is 3.

The volume of the sphere that snugly fits into the cylinder of volume 432π cube units is 288 cube units.
It is given that
The fall snugly fits inside the cylindrical jarThe ball touches the top and bottom of the cylindrical jarTherefore, from the image attached we can infer that
the diameter of the sphere and the cylinder is the sameLet the radius of the cylinder and the sphere be r units
Let the height of the cylinder be h units.
Hence h = 2r units
We know that the volume of the Sphere is 4/3πr³
The volume of a cylinder is πr²h

Determine whether each function is linear or nonlinear. y-t=n 12 11 13x+
The function y-t = n(12 - 11 + 13x) is linear according to the y-intercept form.
What is linear equation?A first-degree polynomial is a statement that a constant is equal to a first-degree polynomial, or the sum of a group of terms that are each the product of a constant and the first power of a variable.
The formula for a linear equation with n variables is a0 + a1x1 +... + anxn = c, where x1,..., and xn are variables, the coefficients a0,..., and an are constants, and c is a constant.
When there are multiple variables, the equation might be linear for some of the variables but not for others. The equation x + y = 3 is therefore linear in both x and y, as opposed to x + y2 = 0, which is linear in x but not in y.
We have been asked to find if the equation y-t = n(12 - 11 + 13x) is linear or nonlinear.
W know that a equation is linear if its in the y-intercept form
y = mx + b
Lets simplify the equation and we get
y-t = n(12 - 11 + 13x)
y - t = 12n - 11n + 13nx
y = n + 13nx + t
y = 13nx + (t + n)
This equation is in y-intercept form where
y = y
m = 13n
x = x
b = (t + n)
Thus, The function y-t = n(12 - 11 + 13x) is linear according to the y-intercept form.

Charlize will be left over with 95.6% of her total salary if her student loan payments are $325.00 per month for 144 months .
in the question ,
it is given that
Total salary of Charlize = $87655 .
since the pay is annual the student loan payment will also be for 12 months.
amount Charlize pays per month as student loan = $325
So , the amount Charlize spent on loan payment = $325×12
= $3900
Amount left with Charlize after deduction = $87655 - $3900
= $ 83755
So the percent of amount left with Charlize after deduction
= (amount left)/(total salary) × 100
Substituting the values
we get
percent of amount left with Charlize after loan deduction =(83755/87655)*100
= 0.955507*100
= 95.5507
rounding off to the nearest tenth
≈ 95.6 %

How to get the measure of angle HIF?
Let's look at the given image.
If we draw a vertical line that comes down from H, then we will form a little right triangle.
And if we draw another line that goes up from I we will get another right triangle, such that these two form a rectangle togheter.
Notice that these two triangles will be equivalent, just inverted.
Then the measure of HIF (the angle at vertex I of the left right triangle) will be equal to IHG (the angle at vertex H of the right triangle).

a layer of dirt must be spread over a circular area 3 feet in diameter. how deep a layer will be obtained using 45 cubic feet of dirt?
By solving a linear equation, we can see that the deep of the layer will be 6.37 ft.
How deep will be the layer?For a cylinder of radius R and deep D, the volume is:
V = pi*R^2*D
Where pi = 3.14
In this case, we know that the diameter is 3 ft, so the radius is:
R = 3ft/2 = 1.5ft
And the volume of dirt used is 45 cubic feet, then the deep D must be a solution of the following linear equation:
45 ft^3 = 3.14*(1.5ft)^2*D
Solving this for D, we get:
(45 ft^3)/(3.14*(1.5ft)^2) = D

What Sets Conditional Probability Apart from Regular Probability?
The probability of one event happening is examined in probability. The relationship between two occurrences that could happen is examined through conditional probability.
Based on the likelihood that the first event will occur, the probability of the second event happening is examined. The likelihood of the preceding event is multiplied by the probability of the subsequent, or conditional, occurrence to determine the conditional probability.

your answer in standard notation, rounding to the nearest tenth.
The diametric size of cell H is 3.86 times larger the diametric size of cell K.
How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, the diametric size of cell H, say y = 3.52×10⁻³ cm
The diametric size of cell K, say x = 9.1×10⁻⁴ cm = 0.91×10⁻³ cm
The ratio of the diametric size of H to K, y/x = 3.52×10⁻³/0.91×10⁻³ = 3.86
Thus, y = 3.86x, the diametric size of cell H is 3.86 times the diametric size of cell K.
