A bird flew from the ground onto a tree branch 5 feet above the ground. What could the bird do next that would make this situation a model of combining a number and its additive inverse?
A.
Fly down 5 feet and return to the ground.
B.
Fly 5 feet higher up onto another tree branch.
C.
Fly to a different tree branch 5 feet above the ground.
D.
Fly into an empty swimming pool 5 feet below ground level.
Answer:
Fly down 5 feet and return to the ground.
Step-by-step explanation:
We are given that A bird flew from the ground onto a tree branch 5 feet above the ground.
We are supposed to find What could the bird do next that would make this situation a model of combining a number and its additive inverse
Additive inverse - What you add to a number to get zero is additive inverse.
The negative of a number.
Now we are told What could the bird do next that would make this situation a model of combining a number and its additive inverse
Since it already flew 5 feet above the ground .
Additive inverse of 5 feet is -5 feet
So, to make the situation of combining a number and its additive inverse
Bird has to flew 5 feet return to the ground i.e.-5 feet
So, a model of combining a number and its additive inverse = 5+(-5)
Hence Option A is correct.
Fly down 5 feet and return to the ground.
Answer:
A is correct

What is the relationship between 2.57×10^4 and 2.57×10^−1 ? Select from the drop-down menus to correctly complete the statement.
A)1000 B)Greater
10,000 Less than
100,000
1,000,000
Answer:
We have the numbers:
2.57×10^4 and 2.57×10^−1
The first thing we can see is that the first number exponent is 4, and the second number's exponent is -1, so the difference between is of 5.
If we calculate the quotient between the numbers we have:
(2.57×10^4)/( 2.57×10^−1) = (2.57/2.57)*(10^4/10^-1) = 1*10^(4 - (-1)) = 10^5
Then the first number is 10^5 times bigger than the second number, then the first number is 100,000 greater than the second one.

What is the equation of the line shown in this graph?
Drag and drop the expressions to write the equation of the line in slope-intercept form.
y = __ + ___
choices : 4x , 2x , -x , -2x , 2 , 4 , -4 , -2
The equation of line is y = -1/2 x + 5/2 or x+ 2y = 5.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
The points from the Graph are (1, 2) and ( 4, -4).
So, the slope is
= (4-1)/(-4-2)
= 3/(-6)
= -1/2
and, using the slope intercept form
(y- 2)= m (x- 1)
y-2 = -1/2 ( x-1)
y-2 = -1/2x + 1/2
y= -1/2 x + 1/2 + 2
y = -1/2 x + 5/2
2y = -x + 5
x+ 2y = 5
Hence, the equation of line is y = -1/2 x + 5/2 or x+ 2y = 5.

Eva is arranging 24 photos in an album. How many different ways can she arrange the photos so that the number of photos on each page is the same?
Final answer:
To determine how Eva can arrange 24 photos in an album so that each page has the same number of photos, we need to find the factors of 24. With factors of 1, 2, 3, 4, 6, 8, 12, and 24, there are 8 distinct ways to arrange the photos across the album's pages with each page having the same number of photos.
Explanation:
The student's question is about determining the different ways Eva can arrange 24 photos in an album so that each page contains the same number of photos. To solve this, we need to consider the factors of 24, as the number of photos on each page must be a factor of the total number. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. This means Eva has 8 different page arrangements where each page has the same number of photos.
Now, for each of these arrangements, the order of the photos on each page and the order of the pages themselves can change. If we assume all photos are distinct, the number of ways to arrange the photos on a single page is the factorial of the number of photos per page. However, since Eva is concerned only with the arrangement of the number of photos per page being the same, not the order within the pages, we only need to consider the 8 different page arrangements.

Lucio says he can use counters to represent the number of eggs laid. Explain how he could do this to find out whose chickens laid more eggs
Lucio can use counters to represent the number of eggs laid by each set of chickens. He can then compare the numbers to ascertain which set laid more eggs. Counters provide a simple way to visually represent and compare quantities.
Explanation:Lucio can use counters to represent the number of eggs laid by allocating one counter for each egg. Let's assume Lucio has two sets of chickens from which he collects eggs. He can use different colored counters or different objects to represent the eggs laid by each set. Every time a chicken lays an egg, he places a corresponding counter in a designated area. By the end of a certain period, say one day, he can compare the number of counters in each area. This way, the set of chickens with more counters represents the one that laid more eggs.
Counters provide a simple yet effective way to visually represent and compare quantities in real-world scenarios.

The perimeter of Square A is 24 linear units. The area of Square B is 4 times the area of Square A. What is the area of Square B? What is the perimeter of Square B?show your work
Answer:
area of Square B: 144 quadratic units
perimeter of Square B: 48 linear units
Step-by-step explanation:
The perimeter of a square is
perimeter = 4*L
where L is the length of each square side. For square A:
24 = 4*L
L = 24/4
L = 6 linear units
The area of a square is
area = L^2
For square A:
area = 6^2 = 36 quadratic units
The area of Square B is 4 times the area of Square A. So
area of Square B = 4*area of Square A
area of Square B = 4*36
area of Square B = 144 quadratic units
And the length of the sides of the square B can be computed as
area = L^2
L = sqrt(area)
L = sqrt(144)
L = 12 linear units
Therefore, the perimeter of square B is
perimeter = 4*L
perimeter = 4*12
perimeter = 48 linear units

Balu and Pumba shared ½ of a cake. Balu got to eat twice as much cake as Pumba. What fraction of the whole cake did Balu eat?
Final answer:
Balu ate 1/3 of the whole cake.
Explanation:
To solve this problem, we can use the concept of fractions. Let's say Pumba ate x fraction of the cake. Then Balu ate twice as much as Pumba, which means Balu ate 2x fraction of the cake. Together, Pumba and Balu ate 1/2 of the cake. So we can add their fractions: x + 2x = 1/2. Combining the like terms, we get 3x = 1/2. To solve for x, we divide both sides of the equation by 3: x = 1/2 ÷ 3 = 1/6. Therefore, Balu ate 2x = 2 × (1/6) = 2/6 = 1/3 of the cake.
4. Johnny took a bus 220 miles south to Fort Lauderdale and then 60 miles west to Naples. He flew home. How many miles did he fly home?
Johnny's flight home distance is calculated using the Pythagorean theorem, which comes to approximately 228 miles, treating his southward and westward travels as legs of a right-angled triangle.
Explanation:The question asks about the flight distance Johnny must cover to get home. Since Johnny traveled 220 miles south and then 60 miles west, we can represent this as a right-angled triangle with the southward travel as one leg and the westward travel as the other leg. According to the Pythagorean theorem, which states that in a right-angled triangle the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides, we can calculate Johnny's flight distance home.
Therefore, the calculation would look like this:
Plugging in the numbers:
Johnny's flight distance home is approximately 228 miles.
