Answer:
y = 22.5
Step-by-step explanation:
Here, the 4 angles shown are all exterior angles of the polygon.
The sum of the exterior angles of a polygon is ALWAYS 360°
<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>
y = 22.5
Answer:
I think the answer is C
Step-by-step explanation:
If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%
N- a number
The sum of 18 and a number: 18 + n
The original number is 7 i think.
10(x^2) = 70x
10x^2 - 70x = 0
x^2 -7x =0
Δ= b^2 -4ac
where c doesnt exist=0
Δ= 49
-b ± √Δ /2a
7 ± √49 /2
7±7/2
x is either 14/2= 7
or 1/2, which doesnt work.
Lets see:
10(7^2) = 70•7
10•49 = 490
and that is right.
i hope my logic is correct.
Answer:
7
Step-by-step explanation:
Divide 7/8 by 1/4. (You divide the "supply" of raisins into 1/4 cup "parts".)
Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).
The result is 28/8, which can be simplified ("reduced") to 7.
