Answer:
4 3/5
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
sin 60 = √3/2
so √3/2 = h / 12
height h = 12√3/ 2
= 6√3 inches or 10.39 inches to nearest hundredth.
Volume = area of base * height = 10*8*6√3
= 480√3 in^3 or 831.38 in^3 to nearest hundredth.
Answer:
Graph 1 ➡ y = 1/5 x + 3
Graph 2 ➡ y = 3x
Graph 3 ➡ y = -3x + 5
Graph 4 ➡ y = 1/3 x + 5
Step-by-step explanation:
Remember that slope is basically rise/run, where rise is up and down movement and run is left and right movement.
Also remember the formula for slope is y=mx+b, where m is slope and b is y-intercept. Additionally if y-intercept is 0 you don't write it.
Hope this helps :)
The weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
<h3>Simultaneous equation</h3>
Let
- Weight of tables = x
- Weight of chairs = y
- Cost of 3 tables and 5 chairs is 62.5lbs
- Cost of 3 tables and 2 chairs is 52lbs
3x + 5y = 62.5
3x + 2y = 52
- Subtract the equation to eliminate x
5y - 2y = 62.5 - 52
3y = 10.5
y = 10.5/3
y = 3.5 lbs
Substitute y = 3.5 into
3x + 2y = 52
3x + 2(3.5) = 52
3x + 7 = 52
3x = 52 - 7
3x = 45
x = 45/3
x = 15 lbs
Therefore, the weight of each small tables and chairs in the United States is 15lbs and 3.5lbs respectively.
