Is 3.5 an irrational number

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

Step-by-step explanation:

The unit rate of video tape is $1.66.

One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.

Repetitive subtraction is the process of division. It operates in the opposite direction of multiplication.

Given cost of 3 video tapes = $4.99

to find the cost of 1 tape,

we can calculate by using division method

cost of 1 tape  = 4.99/3

cost of 1 tape  = 1.66333

cost of 1 tape  = $1.66

Hence the cost is $1.66.

The distance that should be travel in 5 hours is 105,000 km.

Given that,

We know that

Speed = Distance ÷ time

21,000 = Distance ÷ 5

So, the distance is

= 21,000 × 5

= 105,000 km

Therefore we can conclude that the distance that should be travel in 5 hours is 105,000 km.

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.

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.

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.

Step-by-step explanation:

To estimate the value of √97.5÷1.96, we approximate √97.5 to be just under 10, and 1.96 to be about 2. Dividing these estimations, 10 by 2, we get an approximate answer of 5.

The student asked to estimate the value of √97.5÷1.96. First, let's find a reasonable approximation for each number.

For the square root of 97.5, we know that √100 is 10, so we can estimate √97.5 to be slightly less than 10. For 1.96, that's very close to 2, so we can use that for our approximation.

Now, our estimated equation is 10÷2, which is 5. Hence, the estimated value of √97.5÷1.96 is approximately 5.

In performing the division of 5,253 by 101, the result comes out to be 52 with a remainder of 1.

The student's question is asking for the result of dividing 5,253 by 101. To perform this division, you can use long division method.

Here's how you do it:

This implies that 5,253 divided by 101 equals 52 with a remainder of 1.

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.

The simplest form that compares the numbers 4 and 6 is 2:3.

To write the simplest form of a ratio, we need to find the greatest common divisor (GCD) of the given numbers and divide both the numerator and denominator by it. In this case, the GCD of 4 and 6 is 2, so we divide both numbers by 2 to get the simplest form of the ratio. Therefore, the simplest form that compares the numbers 4 and 6 is 2:3.

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.

The equation of line is y = -1/2 x + 5/2 or x+ 2y = 5.

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.

It will take 2 days to process the aluminum collected on Saturday. Each cup of dye can make 1/2 T-Shirt. Each flower bed can make 6 T-Shirts.

To determine how many days it will take to process the aluminum collected on Saturday, we can divide the amount collected by the amount processed each day.
7/4 ton / 7/8 ton/day = (7/4) / (7/8) = 7/4 x 8/7 = 2 days.
Therefore, it will take 2 days to process the aluminum collected on Saturday.

To find out how many T-Shirts each cup of dye can make, we can divide the amount of dye needed for a T-Shirt by the amount of dye in each cup.
3/8 cup / (3/4) cup = (3/8) / (3/4) = 3/8 x 4/3 = 1/2 T-Shirt.
Therefore, each cup of dye can make 1/2 T-Shirt.

To find out how many T-Shirts each flower bed can make, we need to multiply the amount of dye in each color by the number of cups.

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.

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.
