Answer:
7 over 36
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Cuz 9x4=36 so thats your denomanator and 4x7=28 numerator for 28/36 but were not done yet, again 34 as a denomator and 9x1=9 so now u have 9/34!

Equation A: y = 15 − 2z
Equation B: 2y = 3 − 4z
Step 1: −2(y) = −2(15 − 2z) [Equation A is multiplied by −2.]
2y = 3 − 4z [Equation B]
Step 2: −2y = 15 − 2z [Equation A in Step 1 is simplified.]
2y = 3 − 4z [Equation B]
Step 3: 0 = 18 − 6z [Equations in Step 2 are added.]
Step 4: 6z = 18
Step 5: z = 3

Answer:
-1080
Step-by-step explanation:
1 min = -12
90 min = 90 * (-12) = - 1080

Answer:
2.32 feet
Step-by-step explanation:
Given;
The cross section of the bottom of a circular pound has the shape of a parabola
Now,
For the circular parabola, the equation is given as:
y² = 4ax
here,
y is the depth
x is the horizontal distance from the center
a is the constant
also,
at diameter of the pond = 24 feet
and,
at x = 0 ; y = 8 feet
now,
the point 2 feet from the shore with respect to the center of the pond = radius of the pond - The distance from the shore
= - 2 = 10 feet
thus,
at x = 10 feet ; y = 3 feet
thus,
we have
the equation as:
3² = 4a × 10
or
0.9 = 4a
or
a = 0.225
therefore,
we get the equation as;
y² = ( 4 × 0.225 ) × x
and, for point 6 feet away from the shore, i.e - 6 = 6 feet away from the center
we have
y² = ( 4 × 0.225 ) × 6
or
y² = 5.4
or
y = 2.32 feet (negative value is neglected as the depth cannot be negative)
Answer:
I wanna say 48 squared feet
Step-by-step explanation:
3x - 8 = 15
Answer:x = 7.667
Step-by-step explanation:
3x - 8 = 15
+ 8 = 23
3x = 23
divide 3 by 3 and 23 so you get x by itself
answer = 7.667
Answer:
x = 7.667
Step-by-step explanation:
3x - 8 = 15 (Rearrange expression)
-8 - 15 = -3x (Combine like terms)
-23 = -3x (Divide)
x = 7.667
