A 45° sector is 1/8 of the area of the circle, so is (72π m^2)/8 = 9π m^2.
The distributive property of multiplication is a very useful property that lets you rewrite expressions in which you are multiplying a number by a sum or difference.
Answer:
D. Each digit represents 10 times its original value.
Step-by-step explanation:
The Answer to this is: True.
Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 <u>70x - 63y = 462</u> {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6
