Let, the number of hour, she can still watch the T.V. = x
Equation would be: x + 1.5 ≥ 5
Solving the equation:
x + 1.5 ≥ 5
Subtract 1.5 from both the sides,
x + 1.5 - 1.5 ≥ 5 - 1.5
x ≥ 3.5
In short, She can watch 3.5 hours more in that week
Hope this helps!
The answer is A, because you take the square root of both sides and solve. <span />
Answer:
The answer to your question is x = 66.42° and x = 293.6°
Step-by-step explanation:
Data
cos x = 2/5
x = ?
Process
1.- Look at the sign of 2/5.
2/5 is positive so the angle we are looking for is in the first or the fourth quadrant.
2.- Remember the side that the trigonometric function relates
cos x = Adjacent side / hypotenuse
then, adjacent side = 2
hypotenuse = 5
3.- Get cos⁻¹ x
cos⁻¹x = x = 66.42°
4.- If the angle is in the first quadrant x = 66.42°
5.- If the angle is in the fourth quadrant x = 293.6°
Answer:
30
Explanation:
It’s pretty simple actually, you just need to get the square root of 900 by seeing what two equal numbers give you 900. The answer in this scenario would be 30 since 30x30 would give you 900. Since it is a square all sides are equal and your answer would only be 30.
Hope this helped you :)
