Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft
Answer:
14 > -2 (2z + 3)
First you need to distribute the -2 inside the parentheses.
14 > -2(2z) + -2(3)
14 > -4z - 6 -Add 6 to both sides of the equation
14 + 6 > -4z - 6 + 6
20 > -4z -Now divide by -4 on both sides
20 / -4 > -4z / -4
-5 > z
However, when you divide by a negative number, you MUST flip the sign.
So, the answer is:
-5 < z
Hope this helps!
5. 4 is in the tenths place and it is under 5 so it rounds down to 5
The answer is 62 with a remainder of 2.
Hope this helps!
