Answer:

r = 7  

Step-by-step explanation:

In a direct proportionality,

y = rx

Substitute a pair of values for x and y

77 = r × 11

Divide each side by 11

r = 77/11 = 7

Last year, ginger cost $15 per kilogram. Due to a harvest shortage this year, the price of ginger has to increase by 15% per kil
Anastaziya [24]
<h3>Answer:    17.25 dollars</h3>

=======================================================

Explanation:

15% of 15 = 0.15*15 = 2.25

The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars

------------

As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:

1.15*15 = 17.25

This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15

Calculate the center angle a if the lenght of the circular arc 31,4cm and the radius of the circle 9cm​
Fed [463]

Answer:

3.49 radians

Step-by-step explanation:

The arc length formula is s = rФ, where r is the radius and Ф is the central angle.  We know s and r and need to calculate Ф.

From s = rФ we get Ф = central angle = s/r

Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
