For this case what we should do is write correctly the given equation:
 D ^ 2 = W ^ 2 + H ^ 2
 We substitute the values:
 D = 17inch
 H = 9inch
 Substituting:
 17 ^ 2 = W ^ 2 + 9 ^ 2
 We clear the value of W:
 W = root (17 ^ 2 - 9 ^ 2)
 W = 14.4 inch
 Answer:
 
The width of the laptop screen is:
 
D. W = 14.4 inch

ASAP! GIVING BRAINLIEST! Please read the question THEN answer correctly! No guessing.
icang [17]

Answer:

D. temperature(minutes), or t(m)

Step-by-step explanation:

Based on the information given, only the temperature of the coffee and the amount of minutes it sits is involved. This means we can eliminate choices "A," and "B."

When something depends on another, it's outside of the parenthesis. So in this case, the temperature depends on the amount of minutes it sits on the desk, making the temperature outside of the parenthesis.

A service station checks Mr. Gittleboro's radiator and finds it contains only 30% antifreeze. If the radiator holds 10 quarts an
Andrew [12]

Answer:

2.86 quarts ( approx )

Step-by-step explanation:

Given,

The initial quantity of the Mr. Gittleboro's radiator that contains 30% antifreeze = 10 quarts,

Let x quarts of pure antifreeze replaced x quarts of Mr. Gittleboro's radiator to bring it up to a required 50% antifreeze,

So, the quantity of 30% antifreeze radiator after drained off x quarts = (10-x) quarts

Also, the quantity of final antifreeze radiator 50% antifreeze = 10 quarts

Thus, we can write,

30% of (10-x) + 100% of x = 50% of 10

30(10-x) + 100x = 500

300 - 30x + 100x = 500

300 + 70x = 500

70x = 200

x = 2.85714285714 quarts ≈ 2.86 quarts
