This question is based on the equation of circle. Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
Given:
A circle with center (4, -7) and radius 9.
We need to determined the equation describes a circle with center (4, -7) and radius 9.
According to the question,
As we know that, the equation of a circle in standard form is
⇒ (x - h)² + (y - k)² = r²
Where (h, k) are the coordinates of the center and r is the radius.
Here, it is given that, (h, k) = (4, - 7) and r = 9.
Therefore, by putting the given values.
We get,
⇒ (x - 4)² + (y - (- 7))² = 9², that is
⇒ (x - 4)² + (y + 7)² = 81 ← equation of circle
Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

1. Savannah has 5 dogs and she feeds each of them 6 oz of dog food every day. How many
pounds of dog food do they eat each day?
Answer:
0.375 lb
Step-by-step explanation:
For this one all you need to do is convert 6 oz to pounds and to do this
For example to convert an ounce measurement to a pound measurement, use a simple formula. Since one ounce is equal to 1/16 of a pound, the formula for the conversion is:
pounds = ounces ÷ 16
1. Take measurement
2. Divided ounces by 5
3. Round the result to desired decimal places.
And don't just put this answer because I am not very sure.
1.875 pounds of dog food can be eaten by 5 dogs per day.
Pound and ounce based problem:What information do we have?
Number of dogs = 5
Each dog eats per day = 6 oz
Total dog food eaten per day = Number of dogs × Each dog eats per day
Total dog food eaten per day = 5 × 6
Total dog food eaten per day = 30 oz
1 pound = 16 oz
So,
Total dog food eaten per day = 30oz / 16oz
Total dog food eaten per day = 1.875 pound

Is there
a way to place 29 books on shelves so
that each shelf has the same number of books,
with more than one book on each shelf?
Explain.
Answer:
no
Step-by-step explanation:
no because 29 is a prime number, meaning its only factors are 1 and 29. if you were to have more than 1 book on each shelf then you would go into half and quarters of books.
Answer:
29 is only divisible by 1 and 29
so
you could either do one on each shelf or all 29 on one shelf

Consider two consecutive odd positive integers. If their product is 23 more than their sum, what
are the two integers?
Answer:
Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.
Step-by-step explanation:
The value of two consecutive odd positive integers are 5 and 6.
What are Integers?
A whole that can be positive , negative and zero is called integers.
Given that;
The product of two integers is 23 more that their sum.
Let two consecutive odd positive integers are x and x + 2.
Now, By the given condition we can formulate;
x (x + 2) = 23 + x + (x + 2)
x² + 2x = 23 + 2x + 2
x² + 2x = 25 + 2x
x² = 25
Take square root;
x = √25
x = ± 5
Since, Numbers are positive.
So, x = 5
And x + 1 = 5 + 1 = 6
Thus, The value of two consecutive odd positive integers are 5 and 6.
