Answer:
x ≈ 4.1 cm
Step-by-step explanation:
The segment from the centre to the chord is a perpendicular bisector
The third side of the triangle = 14.6 ÷ 2 = 7.8
We now have a right triangle with legs x and 7.8 with hypotenuse 8.8
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 7.8² = 8.8²
x² + 60.84 = 77.44 ( subtract 60.84 from both sides )
x² = 16.6 ( take the square root of both sides )
x =
≈ 4.1 ( nearest tenth )

Answer:
She has to drink 0.05 liters more
Step-by-step explanation:
She has to drink 2.5 liters of water each day.
The total amount of water she drank is
3/4 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
0.75 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
2.45 liters + x liters = 2.5 liters
x liters = 2.5 liters - 2.45 liters
x liters = 0.05 liters
She has to drink 0.05 liters more or has not drunk 0.05 liters.
If she drinks 0.05 liters more she will reach her set goal.
3/4 liters
1 liter= 1000ml
3/4 liters= 3* 1000/4 ml
3/4 liters= 3000/4 ml
3/4 liters= 750 ml
750 ml/ 1000ml = 0.75 liters
Answer:
Solving steps:
<u>find the value of y when x = 1</u>
=> y = 8(1)
multiply 8 by 1
=> y = 8
