Answer:

8ft +10ft+10ft= 28ft

the perimeter of half a circle is

p=½πd+d

but in this case you won't add d since we're not going inside the circle therefore you use this formula ½πd

½×3.14×8 =12.56

12.56+ 28=40.56ft

hope it made sense

Can anyone help out with the first question so I can get an idea with the others?
Oksanka [162]
As you can see, the first number line is divided into tenths (0.1, 0.2, 0.3). So, put 8.152 in between 8.1 and 8.2.

Then, the ends of the next number line should be 8.1 at the start, and 8.2 at the end. You keep going smaller to find the exact spot. So, move 5 places inwards and place the 8.153, between 8.15 and 8.16.

Afterwards, the ends of the last number line should be 8.15 and 8.16. Now, it is divided into thousandths. So, find the third spot. Now, it should be 8.153 correctly labeled.

How do you solve 5/x=x-4
alexandr402 [8]
\frac{5}{x}=x-4\\
x\not=0\\
5=x^2-4x\\
x^2-4x-5=0\\
x^2+x-5x-5=0\\
x(x+1)-5(x+1)=0\\
(x-5)(x+1)=0\\
x=5 \vee x=-1
