1 answer:
Given is : Madison wants to make cookies for her little sisters birthday party. She is cutting a roll of cookie dough into pieces that are 1/2 inch thick
The thickness of the roll of cookie dough is = inches
Thickness of the complete roll = 13 inches
Number of cookies that can be cut are = = 26
Hence, Madison can cut/make 26 cookies from the roll.

The nearest whole number the diameter of the circle is 5.0 cm.
<u>Given the following data:</u>
- Circumference of a circle = 15.4 cm
To estimate to the nearest whole number the diameter of the circle:
In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.
<h3>How to calculate the circumference of a circle.</h3>Mathematically, the circumference of a circle is given by the formula:
<u>Where:</u>
- D is the diameter of a circle.
Making D the subject of formula, we have:
Substituting the given parameters into the formula, we have;
D = 4.90 cm
To the nearest whole number:
D = 4.90 ≈ 5.0 cm

Answer:
a) is demonstrated below, b) T=1.462N, c) T=14.6N
Step-by-step explanation:
a) Refer to the attached diagram.
Since the bird is standing in the middle of the line and each half is a straight line, Ta=Tb, so we will call the tension T=Ta=Tb and Tay=Tby
By trigonometry Tay=Ta·Sinθ
Since the system is in equilibrium W=Tay+Tby then:
W=2·Tay=2·Ta·Sinθ=2·T·Sinθ
Since W=mg, being m the mass of the bird and g, gravity:
Isolating T, we demonstrate that
b) Replacing θ=5º, m=0.026kg and g=9.8m/s² in the last equation, we can get the tension in Newtons:
c) With θ=0.5º
