Answer:
a)B)9π
b)G)16π in²
Step-by-step explanation:
according to the question
as we know
C/d=π
C=dπ
Therefore
C=9π
Answer:
27
divide 42 by 33 and multiply by 100 =127
Answer:
(10, 3)
Step-by-step explanation:
Solve by Substitution
2x − 4y = 8 and 7x − 3y = 61
Solve for x in the first equation.
x = 4 + 2y 7x − 3y = 61
Replace all occurrences of x with 4 + 2y in each e quation.
Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61
x = 4 + 2y
Simplify 7 (4 + 2y) − 3y.
28 + 11y = 61
x = 4 + 2y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
11y = 33
x = 4 + 2y
Divide each term by 11 and simplify.
y = 3
x = 4 + 2y
Replace all occurrences of y with 3 in each equation.
Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)
y = 3
Simplify 4 + 2 (3).
x = 10
y = 3
The solution to the system is the complete set of ordered pairs that are valid solutions.
(10, 3)
The result can be shown in multiple forms.
Point Form:
(10, 3)
Equation Form:
x = 10, y = 3
Answer:
C
Step-by-step explanation:
10^5=100,000
100,000*4.7=470,000 (Four Hundred Seventy Thousand)
10^8=100000000
100000000*3.9=390,000,000 (Three Hundred Ninty Million)
10^5=100,000
100,000*5.2=520,000 (Five Hundred Two Thousand)
