Answer:
Kabuls = 7.5
Carumpts= 0.85
Step-by-step explanation:
Let x represent the price of kabuls
Let y represent the price of carumpts
8x + 2y= 61.70......equation 1
3x + 10y= 31.........equation 2
Multiply equation 1 by 3 and equation 2 by 8
24x + 6y= 185.1
24x + 80y= 248
-74y = -62.9
y= 62.9/74
y= 0.85
Substitute 0.85 for y in equation 1
8x + 2(0.85) = 61.70
8x + 1.7= 61.70
8x = 61.70-1.7
8x = 60
x= 60/8
x= 7.5
Hence the dollar value for kabuls is 7.5 and carumpts is 0.85
Answer:
1/3(3.14)2^2(24)
Step-by-step explanation:
The volume of a cone is given by the formula;
1/3πr³
Considering the radius is 2 cm and the height is 24 cm (4 times the diameter).
Therefore;
Volume = 1/2(3.14)2²(24)
This can be used to calculate the volume.
Answer:
3:5
The ratio of pens:pencils is 3:5.
Step-by-step explanation:
Station A is at a distance of 28.83 miles from the storm
<h3>
Sine rule</h3>
Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:
From the diagram:
Also:
Hence:
- C + A + B = 180°
- C + 29 + 124 = 180
- C = 27°
b = distance station A from the storm, c = AB = 27 miles
Using sine rule:
Station A is at a distance of 28.83 miles from the storm
