Answer:
11.99 ft
Step-by-step explanation:
The formula for the volume of a cyl. of radius r and height h is V = πr²h.
Solving this immediately for h yields:
V
h = ----------
πr²
Inserting the known quantities results in:
V 1356.48 ft³
h = ---------- = ---------------------- Note that r = (1/2)d, so r = (1/2)(12 ft) = 6 ft
πr² 3.14159 (6 ft)²
= 11.994 ft
The height of the cyl. is 11.99 ft (to the nearest hundredth foot)
Using a linear function, it is found that the expression to find the perimeter of the composite figure made up of t triangles is:
<h3>What is a linear function?
</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
<h3>What is the perimeter of a figure?</h3>
- The perimeter of a figure is the<u> sum of all it's outside dimensions.</u>
Researching the problem on the internet, it is found that:
- When the figure is made of 1 triangle, the perimeter is of 12, as it is an isosceles triangle with two dimensions of 5 and one dimension of 2.
- When the figure is made of 2 triangles, the perimeter is of 14. For 3 triangles, it is of 16, and so on...
- Hence, when the number of triangles changes by 1, the perimeter changes by 2, which means that the slope is , and the equation is:
When t = 1, P(t) = 12, hence, we can find b:
Hence, the expression is:

Answer:
Greatest sack = 42
1 candy bar and 3 lollipops
<em></em>
Step-by-step explanation:
Represent Candy bars with C and Lollipops with L
Solving (a): Greatest number of treat sacks
To solve this, we simply calculate the GCF of C and L
Hence, the GCF is
Hence, greatest number of sack is 42
Solving (b): Number of treat in each sack.
To do this, we simply divide the number of C and L by the calculated GCF
For C:
For L:
<em>Hence, 1 candy bar and 3 lollipops</em>
