Answer:

$15.21

Step-by-step explanation:

17% of $13=0.17*13=2.21

13 (the price of the actual lunch) +2.21= 15.21

Alternatively, you can just do the operation:

13*(1+0.17)=15.21

This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip

Alex Ar [27]

Answer:

the answer is 97 if you're rounding but 99 if you want exactly 95

Step-by-step explanation:

if you add all the previous grades up it'll add up to 376 and then when you add 97 and then divide it by 5 (the total amount of assignments) it'll add up to 94.6 which rounds up to a 95 unless you want it a 95 exactly which would probably be 99

What is the value of x?
Vladimir [108]
We know that

angle F=180°-(40+87)°=53°
applying the law of sines
EF/sin G=EG/sin F
EF=x
EG=13 cm
G=87°
F=53°
so

x/sin 87°=13/sin 53°---------> x=sin 87*(13/sin 53°)-------> x=16.3 cm

The answer is
x=16.3 cm

H^2+14h=-31 Solve by completing the square
matrenka [14]
Since the constant has been moved to the left side, you can move on to the next step which is adding (b/2)² to both sides of the equation.

h² + 14h + (14/2)² = -31 + (14/2)²

Simplify the parenthesis and exponent.

h² + 14h + 7² = -31 + 7²

h² + 14h + 49 = -31 + 49

h² + 14h + 49 = 18

Factor the expression of the left.

(h + 7)(h + 7) = 18

Take the square root of both sides.

√(h + 7)(h + 7) = ± √9 • 2

(h + 7) = ± 3√2

h + 7 = ± 3√2

Subtract 7 from both sides.

You solutions are:

h = -7 + 3√2 → -2.7573 → -2.76

h = -7 - 3√2 → -11.2426 → -11.24
