Answer:
49Pi cm^2
Step-by-step explanation:
Area of a circle = Pi r^2
Radius r = 7
Area = Pi x 7^2
= Pi x 7 x 7
= 49Pi cm^2
Answer:
n = 19.2
Step-by-step explanation:
12 / 5 = n / 8
n = 12 * 8 / 5
n = 96 / 5
n = 19.2
Answer:
39in.
Step-by-step explanation:
due to scale, cant be 15, as that would be the same length as other side
cant be 91 otherwise it wouldnt be similar if it had the same length as blue triangle which has 39 not 15 as the top side
Answer:
The relationships are correct and valid
Step-by-step explanation:
The correct question is as follows;
Verify the following
i.[ -3/4]^3 = -27/64
ii. [-2/3]^6 = 64/ 729
We have the solution as follows;
i) we have;
(-3/4)^3
That means ;
-3^3 = -3^3 = -27
4^3 = 64
so;
(-3/4)^3 = -27/64
ii) (-2/3)^6
(-2)^6 = 64
3^6 = 729
Thus;
(-2/3)^6 = 64/729
The value of the integer number n is greater than 5 and less than 9.
Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is use it to compare two statements.
Simplification is to make something easier to do or understand and to make something less complicated.
Shantira is thinking of a number n.
Her first clue is that six less than six times her number is between twenty-four and forty-eight.
Let n be the integer number.
Then according to the condition,
Her first clue is that six less than six times her number is between twenty-four and forty-eight.
24 < 6n - 6 < 48
Add 6, then
30 < 6n < 54
Divide it by 6
5 < n < 9
So the value of the integer number n is greater than 5 and less than 9.
