(36 3/4" + 36 3/8" + 371/2" +z) /4 = 36 5/8"
This is the equation that you would get for the average. Now we just solve for z.
Following PEMDAS you have to mulitply the equation by 4 to get rid of the divide by 4 part.
4( (36 3/4" + 36 3/8" + 371/2" +z) /4 = 36 5/8)
Which does this
36 3/4" + 36 3/8" + 371/2" +z = 146 1/2"
Now you have to add and subtract to get "z" by itself.
36 3/4" + 36 3/8" + 371/2" = 110 5/8"
(110 5/8" + z = 146 1/2" ) -110 5/8"
z= 35 7/8", so the answer is b
Answer:
axis of symmetry x=3/2
vertex (3/2, 0)
Step-by-step explanation:
to find the axis of symmetry we use h = -b/2a
where ax^2 + bx+c
h = -(-12)/2(4)
h= 12/8
h = 3/2
the axis of symmetry is x = 3/2
the x coordinate of the vertex is h x=3/2
to find k, the y coordinate of the vertex, substitute x=3/2 into the equation
y=4x^2-12x+9
y=4(3/2) ^2-12(3/2)+9
= 4 (9/4) - 6*3 +9
= 9-18+9
= 0
the vertex (3/2, 0)

From this, we know that Jhon had originally $1400.37 in the bank account.
Answer:
10.35 am
Step-by-step explanation:
Find the LCM
LCM = 275 minutes ÷ 60 minutes to change into hours
= 4hrs 35 min
6.00am + 4hrs 35min
= 10.35 am
Answer:
x = 13°
Step-by-step explanation:
5x+15°=7x-11°
5x-7x = -11°-15°
-2x = -26° divide both sides by -2
x = 13°
5x+15° = 5×13°+15° = 80°
7x-11° = 7×13° -11°. = 80°
