Answer: Yes.
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case the distance between Doreen’s house and the tower) and a and b are the other sides.
Replacing with the values given:
c^2 = 16^2 + 12^2
c^2 = 256+144
c^2 = 400
c = √400
c = 20 miles
So, she is within the area serviced by the tower (20 miles)

Answer:
x = 2
or 
Step-by-step explanation:
Subtract 5x from both sides. This leaves us with 2x = 5. Now divide both sides by 2 to isolate x. If you want an improper fraction you can stop at x = . If you want a mixed number you will have x = 2.

Answer:
x = 1 ,or x = -7
Obviously, the true answer is not in the options given.
Step-by-step explanation:
x² + 6x - 6 = 10
The above equation can not be factorized, hence the use of Almighty Formula.
x = [-b +- √b² - 4ac] / 2a
Where a = 1, b = 6, c = -6
x = [-6 +- √6² - (4*1*-6)] / 2*1
x = [-6 +- √36 - (-24)] / 2
x = [-6 +- √36 + 24] / 2
x = [-6 +- √60] / 2
x = [-6 +- 7.75] / 2
x = [-6 + 7.75] / 2 ,or x = [-6 - 7.75] / 2
x = 1.75/2 ,or x = -13.75/2
x = 0.875 ,or x = -6.875
Approximately
x = 1 ,or x = -7
Answer:
4.7 miles
Step-by-step explanation:
if she walks 10,000 steps at 30 inches then we have 300,000 inches...
30000 divided by 63360 (inches in a mile)
4.7 rounded
Answer:
<span>a=15</span>
Explanation:
<span>5a−10b=45</span> , when <span>b=3</span>
Substitute the value of b into the equation.
<span>5a−10<span>(3)</span>=45</span>
Solve for a.
<span>5a−10<span>(3)</span>=45</span>
<span>5a−30=45</span>
<span>5a=75</span>
