Answer:

The perimeter of the rectangle is 12x + 4

Step-by-step explanation:

4x + 4x is 8x

2 + 2 is 4

2x + 2x is 4x

8x + 4x is 12x

12x + 4

What is the angle of 3:25?
Veronika [31]
The answer is 47.5. 

The equation for this problem is:

60(H) + (M) divided by 2.
Plug the numbers of the time in the equation,

60(3) + (25) / 2 

180 + 25 / 2 = 205/2

205/2 = 102.5 (Smaller Angle)

Then you calculate the angle between 12 and the Minute hand 25.

0m= 6M
0m = 6(25)
0m= 150

Final step is to subtract the hour angle by the minute angle.

H(102.5)-(150)= -47.5 or 47.5 degrees

Hope this helps,

Can someone please help me with b, d, and 9-13? I already drew a number line, thanks in advance! :)
inessss [21]
B)
\frac{3}{13}  = s
d)
\frac{5}{4}  = s
9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,

10)
{2}^{2}  = 4
{3}^{2}  = 9
so {5, 6, 7, 8} is the answer

11) for some reason it won't let me insert a picture but put place
\sqrt{4}
above 2, and then place
\sqrt{9}
above 3, and then place
\sqrt{7}
in between 2 and 3, but place it a little closer to three since
\sqrt{7}  = 2.65
12) place
\sqrt{5}
between 2 and three, but closer to two since
\sqrt{5}  = 2.24
and also
\sqrt{5}  <  \sqrt{7}
and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.


I hope this helped and if not, message me and ill try to explain!
