What is the simplified form of the expression below? 2 1/2 • 32 1/2

Answer:

NOT the graph A and the graph B.

Step-by-step explanation:

y = mx + b

m - slope

b - y-integer

If m > 0 then the function is increasing.

if m < 0 then the function is decreasing.

We have y = -2x + 3

m = -2 < 0 the function is decreasing

b = 3 y-intercept = 3

The x-intercept: y = 0. Substitute

0 = -2x + 3     add 2x to both sides

2x = 3    divide both sides by 2

x = 1.5

Therefore your answer is C or D (look at the picture)

Final answer:

To find the missing term in the proportion 72:24 = 15:__, you divide 72 by 24 to find the common ratio, which is 3. Then, you set 15/x = 3 and solve for x, giving you the missing term 5, making the proportion 72:24 = 15:5.

Explanation:

To find the missing term in the proportional relationship 72:24 = 15:__, we can set up a proportion where both ratios are equal. We know that 72 divided by 24 equals 3, so the missing term, which we'll call x, needs to satisfy the equation 15/x = 3.

By cross-multiplying, we get:

15 * 1 = 3 * x

15 = 3x

x = 15 / 3

x = 5

Therefore, the missing term is 5, and the proportion correctly reads 72:24 = 15:5.

Hello,

Question:

George jogged a total distance of 9 and 1 over 2 miles during the months of October and November. If George only jogged 1 over 4 mile every day, which expression shows the number of days in which he went jogging?

We know:

He jogged 9 1/2 miles during October and November

1/4 mile every day

Answer:

9 and 1 over 2 divided by 1 over 4

No because there will be a time when you need to determine the absolute value for instance: Absolute values are often used in problems involving distance and are sometimes used with inequalities

2.50 x 8.00= 10.50. :)

The relationship between the number of drinks bought and the total cost is represented by the equation [tex]C = 2.50 \times d[/tex], with d being the number of drinks. A table can be used to display this relationship, indicating the incremental increase in cost with each additional drink.

To represent the relationship between the number of drinks bought at the fair and the total cost, we can define a variable, let's say d, where d represents the number of drinks purchased. Since each drink costs $2.50, we can write the equation for the total cost C as:

[tex]C = 2.50 \times d[/tex]

Now, let's construct a table to show some examples of how this equation works:

 Number of Drinks (d) Cost (C)   1 $2.50   2 $5.00   3 $7.50   4 $10.00  

The equation C = 2.50  imes d helps us understand that for every additional drink bought, the cost increases by $2.50.

3p + 3q = 36    equation 1

5p + 39 = 40    equation 2

subtracting 39 both sides of equation 1.

5p +39 -39= 40-39

5p =1 ⇒   5p/5 = 1/5     ⇒ p = 1/5

putting value of p in equation 1.

3(1/5) +3q =36

3/5 +3q  =36       equation 3

subtracting 3/5 both sides equation 3 becomes.

3q =36 -3/5

3q=177/5      equation 4

dividing 3 both sides of equation 4

q=59/5

Answer: -3< 0

Step-by-step explanation: this means -3 is less than 0.

As on number line -3 and 0 are marked. We know 0 is origin if we go rightward i .e towards the positive number all numbers are greater than zero.

But if we move leftward on number line the numbers are less than zero.

The coordinates of the entrance to the new city park on this map should be (-5, -3).

In Mathematics and Geometry, a reflection over or across the y-axis or the line y = 0 is represented by this transformation rule .

This ultimately implies that, a reflection over or across the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of the point for the school entrance (5, -3), we have the following coordinates of its image;

(x, y)         →              (-x, y)

(5, -3)        →         (-5, -3)

Step-by-step explanation:

To express a counting problem as a ratio you should divide the number of things before the word "to" by the number of things after the word "to". A ratio can be expressed as a fraction or separating the two numbers with a colon (a:b).

Let's apply this to each one of our problems.

11. Here we have triangles to rectangles, so we are going to divide the number of triangles by the number of rectangles.

We can count 2 triangles and 8 rectangles from our picture, so

Triangles to rectangles = [tex]\frac{NumberofTriangles}{NumberifRectangles} =\frac{2}{8}[/tex]

Notice that both numerator and denominator of our ratio are divisible by 2, so simplify it, we just need to divide them both by 2:

[tex]\frac{2}{8} =\frac{\frac{2}{2} }{\frac{8}{2} } =\frac{1}{4}[/tex]

So the ratio from triangles to rectangles is [tex]\frac{1}{4}[/tex] or [tex]1:4[/tex]

which means that for 1 triangle there are four rectangles.

12. Here we have soccer balls to footballs, so we are going to divide the number of soccer balls to the number of footballs and simplify our resulting fraction. We have 6 soccer balls and 10 footballs in our picture

Soccer balls to footballs = [tex]\frac{NumberofSoccerBalls}{NumberofFootballs} =\frac{6}{10} =\frac{\frac{6}{2} }{\frac{10}{2} } =\frac{3}{5}[/tex]

For every 3 soccer balls there are 5 Footballs.

13. Here we have kittens to puppies or puppies to kittens. We know that there are 36 Kittens and 12 puppies.

- Kittens to puppies = [tex]\frac{NumberofKittens}{NumberofPuppies} =\frac{36}{12} =\frac{\frac{36}{12} }{\frac{12}{12} } =\frac{3}{1}[/tex]

For every 3 kittens there is a puppy.

- Puppies to kittens = [tex]\frac{Number of Puppies}{NumberofKittens} =\frac{12}{36} =\frac{\frac{12}{12} }{\frac{36}{12} } =\frac{1}{3}[/tex]

For each puppy there are 3 kittens.

Step-by-step explanation:

by subtracting the first two numbers then the next two you will see the pattern.

Answer:

An integer is a whole number  that can be positive, negative, or zero

The negative of a negative number is positive. -(-3) = +3

The negative of a positive number is negative. -(3) = -3

Zero can neither be positive nor negative

well first you want to do 21/32 and you get 0.6562

then youll do 7/8 you get 0.875

then youll divide 0.6562 by 0.875 you get 0.7499

then it would be 7499/10000 converted back into a fraction

To divide fractions like 21/32 divided by 7/8, we multiply the first fraction by the reciprocal of the second, getting (21 times 8)/(32 times 7) which simplifies to 3/4.

The subject in your question is Mathematics, specifically division of fractions. To divide fractions, we need to first understand the concept of reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and the denominator. So the reciprocal of 7/8 is 8/7. When you divide by a fraction, it's the same as multiplying by its reciprocal. Therefore, 21/32 divided by 7/8 equals 21/32 times 8/7.

To further solve this, you multiply the numerators together to get a new numerator and the denominators to get a new denominator. So you get (21 times 8)/(32 times 7) which is 168/224. When you simplify this fraction, you should get 3/4. So, 21/32 divided by 7/8 is 3/4.

First, model it out in an equation, and lets say x is the amount carrie walked

x+2x+3x=15

Then, combine like terms

6x=15

then divide

2.5

So now we have carries walk speed, then we go by the question, multiply 3 by 2.5 for amy, and 2 by 2.5 for marcus

carrie walked 2.5 miles

marcus walked 5 miles

amy  walked 7.5

To find out how many miles Amy, Marcus, and Carrie each walked, algebra is used. Carrie walked 2.5 miles, Marcus walked twice as much (5 miles), and Amy walked three times as much as Carrie (7.5 miles), totaling 15 miles.

The student is asking how many miles Amy, Marcus, and Carrie each walked if together they walked a total of 15 miles in the Wilbur School Walkathon, with Marcus walking twice as far as Carrie, and Amy walking three times as far as Carrie. To solve this problem, we can use algebra. Let's denote the number of miles Carrie walked as c. According to the problem, Marcus walked twice as far as Carrie, so Marcus walked 2c miles. Amy walked three times as far as Carrie, therefore Amy walked 3c miles.

Total distance walked by all three together is 15 miles.

Carrie walked c miles.

Marcus walked 2c miles.

Amy walked 3c miles.

The sum of their distances is equal to the total distance, so we can write the equation c + 2c + 3c = 15. When we add up the left side, we get 6c = 15. To find out how many miles Carrie walked, we divide both sides of the equation by 6, resulting in c = 15 / 6, which simplifies to c = 2.5. Carrie walked 2.5 miles.

Since Marcus walked twice as much, Marcus walked 5 miles (2 times 2.5). And since Amy walked three times as much as Carrie, Amy walked 7.5 miles (3 times 2.5).

Greater than = >

Put it all together:

6n > n + 20

2.5 times 0.3 is 0.7500 when expressed to four decimal places, taking into account the correct amount of significant figures.

The question asks to calculate 2.5 times 0.3 and express the result to four decimal places. To perform this multiplication, we multiply

2.5 × 0.3 = 0.75.

When expressing the result with four decimal places, we add extra zeros as necessary, resulting in 0.7500. It's important to remember that calculators provide results that must be rounded to reflect the number of significant figures of the initial numbers involved in the calculation.

To estimate the number of bottles Margaret can fill, multiply the daily milk production (21.7 liters) by the number of production days (280) to get the total milk produced, then divide this by the volume of one bottle (0.5 liters) to determine the number of bottles (12152).

Estimating Number of Bottles from Milk Production

Margaret has goats that produce an average of 21.7 liters of milk a day for 280 days. The key task here is to estimate how many half-liter bottles could be filled with this amount of milk. Since each bottle holds half a liter, we need to calculate the total volume of milk and then divide it by the volume of one bottle, which is 0.5 liters.

Therefore, Margaret would be able to fill an estimated 12152 half-liter bottles with the milk produced.

If it's $2.70 now, the cost would be $4.45 in 1995.

To find the 1995 cost of a movie ticket that was $2.70 in 1980, divide the 1995 CPI by the 1980 CPI and multiply by the 1980 price. The calculation yields a cost of approximately $4.99 for a movie ticket in 1995.

To calculate the cost of a movie ticket in 1995 using the Consumer Price Index (CPI) from 1980 to 1995, we can use the formula to adjust prices based on inflation:

Let's assume the cost of a movie ticket in 1980 was $2.70. The CPI for 1980 is 82.4, and for 1995 it is 152.4. We calculate the ratio as 152.4 / 82.4 = 1.8495.

Multiplying the 1980 ticket price by this ratio gives us:

$2.70 * 1.8495 = $4.99 approximately.

Therefore, the cost of a movie ticket in 1995, adjusted for inflation, would be about $4.99.
