You will need 3 to 4 yards of concrete for a footer that's 1 foot wide and 12 inches deep.
Answer:
Extra Miles walked by Alana = 1.625 miles
Step-by-step explanation:
Alana = 4 3/4 or 19/4
Bhavesh = 3 1/8 or 25/8
Extra Miles Alana walked = 19/4- 25/8
Extra miles Alana walked = <u>19(2) - 25</u>
8
Extra miles Alana Walked = <u>38-25</u>
8
Extra Miles Alana Walked = 1.625 miles
Solving a quadratic equation we can see that the negative number is -15.5

How to find the number?</h3>
Let's define x as the number. We know that x is negative, so x < 0.
Now, the statement can be rewritten as:
x*(2x - 3) = 527
Now we can solve this for x, we will get:
2x^2 - 3x = 527
2x^2 - 3x - 527 = 0
This is a quadratic equation, the solutions are given by:
x = (3 ± √( (-3)^2 - 4*(2)*(-527)) )/(2*2)
x = (3 ± 65)/4
We know that x is negative, then we only care for the negative solution, which is:
x = (3 - 65)/4 = -62/4 = -15.5
The negative number is -15.5

The pattern is it goes up by 7 twice then goes down by 2. Hope this helped!
Answer:
The value of X is 75°
<EFB +105°=180° (Being straight line)
<EFB=180-105
<EFB= 75°
X = <EFB = 75°. (corresponding angle)
