Step-by-step explanation:
π is an irrational number
Reason:-
π is defined as the ratio of the circumference of a circle to the diameter of the circle
⇛π = C/d
The diameter and the Circumference of a circle are incommensurable.i.e.there does not exist a common unit to measure that allows us to measure the both. If you measure accurately then atleast either C and d is irrational. So π is regarded as Irrational number.
The decimal expansion of π is non terminating and non recurring decimal.

22/7 = 3.142857142857...
It is a non terminating and recurring decimal
it is a rational number.
We know that
The decimal form of a rational number is either terminating or non terminating and recurring decimal.
The value of π is closely nearer to 22/7
π= 3.1415...
π≠22/7
We often take 22/7 as an approximate value of π
Answer: From the above given options option (c) {π is irrational and 22/7 is rational} is your correct statement.

Mark deopsits $500 into a bank account. He gets a 3% interest rate. How much money will Mark earn in interest over 5 years?
$150
$750
$75
$10
Simple interest formula :
total = starting amount x (1 + ( interest rate x time))
total = 500 x (1 + (.03 x5))
Total = 575
Interest = 575-500 = 75
answer: $75
can someone help me please
Answer:
x=17°
Step-by-step explanation:
The opposite angles, will always be the same. so the the angle across from 163° will be 163
so 163°-x°=180°
Because straight angles = 180°
You'd get x°=17°

select all of the equations that represent a nonlinear function
A. y= 3x(square)+9x+6
B. y=3x-10
c. y=2x+9x
d. y=x(3x+10)
e.y=x/3+10
Answer:
a. y = 3x² + 9x +6
d. y = x(3x + 10)
Step-by-step explanation:
Most equations that have a squared variable are going to be nonlinear.
If you distribute the x in the d equation you get this: y = 3x² + 10x
Choices b, c, and e are going to be linear because there is only one variable, and those variables do not have exponents.

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided You (or your parents) purchase a new car for $19,725.00 plus 4.75% sales tax. The down payment is $2,175.00 and you (or your parents) have an average credit rating. How much interest is accrued after the first month? Credit New Car APR (%) Used Car APR (%) 5.40 Excellent 5.65 6.35 Good 5.95 16.30 6.90 Average 17.60 Fair 7.55 9.80 10.0 Poor
Using simple interest, it is found that $97.06 of interest is accrued after the first month.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
[tex]I(t) = Prt[/tex]
In which:
P is the principal.r is the interest rate, as a decimal.In this problem, first we have to find the total price of purchase of the car, which is $19,725.00 plus 4.75% sales tax, hence:
[tex](1 + 0.0475) \times 19725 = 1.0475(19725) = 20662[/tex]
Then:
Considering a down payment of $2,175, the principal is of P = 20662 - 2175 = 18487.New car and average credit rating, hence the interest rate is of 6.30%, that is, r = 0.063.We want the interest earned after one month, considering the time is measured in years, we have that [tex]t = \frac{1}{12}[/tex].Then:
[tex]I\left(\frac{1}{12}\right) = 18487(0.063)\frac{1}{12} = 97.06[/tex]
$97.06 of interest is accrued after the first month.

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = 2/3x + 5 (-3, 8)
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
[tex]y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{2}{3}}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
so we're really looking for the equation of a line whose slope is 2/3 and passes through (-3 , 8)
[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{8})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{\cfrac{2}{3}}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-8=\cfrac{2}{3}(x+3)\implies y-8=\cfrac{2}{3}x+2\implies y=\cfrac{2}{3}x+10[/tex]

[tex] 8a + 3b = 7 [/tex]
[tex] 3b = 7 - 8a [/tex]
[tex] b = \dfrac{7 - 8a}{3} [/tex]

Answer:
Median: 50
Mode: 52
Step-by-step explanation:
To find the median, you arrange all of the numbers in order and find the number in the middle.If the number of values is an even number, the median will be the average of the two middle numbers.
The mode is the number that occurs the most in a set of data.
What is the lateral surface area of the square pyramid represented by this net?
Answer:
340 ft²
Step-by-step explanation:
From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).
First, find the area of the square.
Area of a square = width x length = 10 x 10 = 100 ft²
All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.
Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²
So the total area of all 4 triangles = 4 x 60 = 240 ft²
Therefore the total surface area = 100 + 240 = 340 ft²
Answer:
340 ft²
Step-by-step explanation:
The surface area of a shape is basically the area of its faces.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
1. First, Let's find the area of the triangles. To find the area of a triangle, we need to multiply the height and the base and then divide the product by 2.
[tex]\rightarrow \text{Area of triangle} = \dfrac{12 \times 10}{2}[/tex]
Now, let's find the area of the triangle by simplifying the RHS.
[tex]\rightarrow \text{Area of triangle} = 6 \times 10[/tex]
[tex]\rightarrow \text{Area of triangle} = 60 \ \text{ft}^{2}[/tex]
Since there are four triangles, we need to further multiply the area of the triangle by 4 to find the area of four triangles.
[tex]\rightarrow \text{Area of four triangles} = 4(60)[/tex]
[tex]\rightarrow \text{Area of four triangles} = 240 \ \text{ft}^{2}[/tex]
2. Now, let's find the area of the square. To find the area of the square, we need to square the side length.
[tex]\rightarrow \text{Side length} = 10 \ \text{ft}[/tex]
[tex]\rightarrow \text{Area of square} = 10^{2}[/tex]
[tex]\rightarrow \text{Area of square} = 100 \ \text{ft}^{2}[/tex]
3. Lastly, let's find the surface area. To find the surface area of the figure, we need to sum up the area of the triangles and the area of the square.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 240 + 100}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 340 \text{ft}}^{2} }[/tex]
