Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
Each meter costs $2. So, the total cost will be:
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
Subtract:
So, 65.21 meters of ribbon will be left.

<h3>How to graph the trigonometry function?</h3>The trigonometry function is given as:
y = 5 sin(4x)
To plot the graph, we use the following domain:
x > 0
This represents the minimum value of x
Also, we use
x < π/2
This represents the maximum value of x
When the domain are combined, we have:
0 < x < π/2
This means that the domain that gives a complete cycle is 0 < x < π/2

Answer:
D
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,
area of triangle
= ½ ×s ×s
= ½s²
Given that the area of the triangle is 12.5 units²,
½s²= 12.5
Multiply both sides by 2:
s²= 12.5(2)
s²= 25
Square root both sides:
s= 5 units
(reject negative value since s > 0)
Answer:
65°
Step-by-step explanation:
x = 180 - 44 - (180-109) = 109 - 44 = 65°
