Answer:
12.5 pie , 39.25 using pie=3.14, and 39.28 to be exact
Step-by-step explanation:
BTW n=pie
10in= Diameter
5in=Radius
Area=n5^2
= 25n/2
=12.5n
12.5 times 3.14= 39.25
22/7 times 12.5= 39.2857143

Select the correct answer. Which number has a terminating decimal expansion? A. 2/7 B.√12 C. 5/8 D. 2/11
Answers
Answer:
Option C is correct option.
Step-by-step explanation:
We need to determine which number has a terminating decimal expansion.
Terminating decimal
A decimal number that contains a finite number of digits after the decimal point is called terminating decimal .
for example 0.123 is terminating decimal as it has finite number of digits after decimal point.
Now, we will look at each option to find the terminating decimal
A. 2/7
Converting in decimal form: 0.28571....
As it doesn't contain finite numbers after decimal point, so 2/7 is not terminating decimal.
B.√12
Converting in decimal form: 3.46410....
As it doesn't contain finite numbers after decimal point, so √12 is not terminating decimal.
C. 5/8
Converting in decimal form: 0.625
As it contain finite numbers after decimal point, so 5/8 is terminating decimal.
D. 2/11
Converting in decimal form: 0.18181....
As it doesn't contain finite numbers after decimal point, so 2/11 is not terminating decimal.
Therefore, Option C is correct option.

if y varies inversely as x and y=23 when x=8 find y when x=4
Answers
EQUATION:
[tex]y = \frac{k}{x} [/tex]
––––––––
First, find the constant of variation k using the formula k=xy.
[tex]23 = \frac{k}{8} [/tex]
[tex]k = (8)(23)[/tex]
[tex]k = 184[/tex]
––––––––
Then, find y if x is equal to four using the formula y=184/x.
[tex]y = \frac{184}{x} [/tex]
[tex]y = \frac{184}{4} [/tex]
[tex]y = 46[/tex]
Final Answer:
y = 46You and your friend go to a taco truck for lunch. You order 3 soft tacos and 3 burritos and spend $11.25. Your friend orders 4 soft tacos and 2 burritos and spends $10.00.
Answers
Answer: See explanation
Step-by-step explanation:
Let soft tacos be x
Let burritos be y
3x + 3y = 11.25 ......... i
4x + 2y = 10.00 ......... ii
Multiply equation I by 4
Multiply equation ii by 3
12x + 12y = 45 ....... iii
12x + 6y = 30 ....... iv
Subtract iv from iii
6y = 15
y = 15/6 = 2.5
A burrito cost $2.50
Since 3x + 3y = 11.25 .
3x + 3(2.50) = 11.25
3x + 7.50 = 11.25
3x = 11.25 - 7.50
3x = 3.75.
x = 3.75/3
x = $1.25
A soft tacos is $1.25

how do you solve systems by graphing
Answers
Answer:
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

B. g(x)=16x^2
C. g(x)=1/4x^2
D. g(x)=(4x)2
Answers
Answer:
D. g(x)=(4x)^2
Step-by-step explanation:
(A.P.E.X)
The function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.
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.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
A. g(x)=4x²
B. g(x)=16x²
C. g(x)=1/4x²
D. g(x)=(4x)²
It is given that:
f(x) = x²
From the graph as we can see the function f(x) is the parent function and g(x) is transformed function.
The function g(x):
g(x) = ax²
Plug x = 1
g(x) = 4
4 = 1²a
a = 4
g(x) = 4x²
Thus, the function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.
