Answer: 3 rolls of tape
Step-by-step explanation:
1. Make an equation:
2 3/4x=8 1/4; x=number of rolls of tape
2. Divide both sides by 2 3/4 to isolate x:
x=8 1/4 divided by 2 3/4
3. Simplify:
x=3
Have a nice day! :D
Answer:
The rectangle is 3.2 cm by 12.6 cm
Step-by-step explanation:
See attached image for a diagram.
Choose <em>w</em> to represent the width because the length is described by referring to the width: it's 3 more than (add 3) triple (multiplied by 3) the width.
Length = 3w + 3
The diagonal forms two right triangles, each with leg = <em>w</em>, other leg = 3<em>w</em> + 3, hypotenuse = 13.
The Pythagorean Theorem says so
Now solve using the Quadratic Formula with .
The negative root makes no sense as a distance, so the width of the rectangle is 3.2 cm. The length is 3(3.2) + 3 = 12.6 cm.

Answer:
1) For : and , 2) For : and
Step-by-step explanation:
The polynomial is a second-order polynomial of the form . By direct comparison, we construct the following system of equations:
(1)
(2)
By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both and are integers. We assume two arbitrary integers for :

2)
Answer:
The weight of Shanu's dog now is 21.375 pounds.
Step-by-step explanation:
We are given that Shaun's dog weighs 22 One-fourth pounds. Shaun weighed the dog after one week and found she had lost Seven-eighths of a pound.
And we have to find the weight of the dog after exercise.
The Original weight of Shaun's dog =
Converting the above mixed fraction into an improper fraction we get;
=
Now, it is stated that after walking an extra mile every day, Shanu's dog lost Seven-eighths of a pound, that is =
So, the weight of Shanu's dog now = Original weight - Weight after exercise
=
Making denominator same for both the fractions;
=
=
=
= = 21.375 pounds.
Hence, the dog weigh 21.375 pounds now.
