Rational number between 1.2 and 1.3 is 1.25 right?

77 - 3x = 5

subtract 77 from both sides : -3x = -72

divide by -3 on both sides to get x by itself : x = 24

The answer is that Mia has 24 friends (x = 24)

Swimmers: 50 children ÷ 12 = 4.2  (you can't have a decimal so you must round up)

5 adults are need.

Dancers: 32 children ÷ 15 = 2.1  (you can't have a decimal so you must round up)

3 adults are need.

Minimum number of adults needed is: 5 for swimmers + 3 for dancers = 8 adults

To round 12,387 with the thousands place underlined, we look at the digit to the right (3) and, since it is less than 5, we round down by keeping the 2 unchanged and turning all the digits to its right to zeros, which gives us 12,000.

Since the next digit (3) is less than 5, we do not increase the value of the underlined digit. Thus, we keep the 2 as it is and change all the digits to the right of it to zeros, resulting in the rounded number 12,000.

This concept is similar to the general principle applied when rounding numbers, which involves looking at the digit immediately to the right of the target place value. If it's 5 or greater, we round up. Otherwise, we round down. Examples of rounding numbers in different situations include:

Significant figures: Rounding an answer like 2,085.5688 to five significant figures would result in 2,085.6 because the first digit to be dropped is greater than 5.

Limiting the final answer to a certain place value: When adding 6527.23 and 2, the answer must be reported as 6528 because the digit 2 has no decimal places that would be significant, so we can only report to the ones place.

When working with calculations such as 119.902, if we need to limit our answer to tenths based on significant figures, we round down to 119.9.

Jannelle could go 4,720 miles hope this helps

4720 miles can be driven with 16 tanks of gas.

Two or more ratios setting to be equal to each other is termed as proportion.

If two quantities are directly proportional, if one increases. other also increases and if one decreases, other also decreases.

If two quantities are inversely proportional, if one increases other decreases and if one decreases, other increases.

Solve this problem using proportional concept.

Jannelle can drive an average of 295 miles on one tank of gas. We have to find the miles she can drive on 16 tanks of gas.

Miles Jannelle can drive on one tank of gas = 295 miles

Miles Jannelle can drive on 16 tanks of gas = 16 × 295

                                                                        = 4720 miles

Hence Jannelle can drive 4720 miles on 16 tanks of gas.

The length of ribbon needed to make 9 bows is 9 times the amount of ribbon needed for one bow, expressed mathematically as 9*x given 'x' is the length of ribbon for one bow.

Based on your query, there appears to be a detail missing, which is the length of the ribbon needed to make one bow. Suppose we denote that length as 'x' units. To find the total length necessary for making 9 bows, we would simply multiply that length by 9. In mathematical terms, this would be expressed as 9*x. So if it takes x units of ribbon to make one bow, it will take 9*x units of ribbon to make 9 bows.

Due to a typo, the exact length of ribbon per bow is unspecified. Assuming a length of [tex]\( x \)[/tex] per bow, for 9 bows the total needed would be [tex]\( 9x \)[/tex] This is akin to scaling up costs for making multiple items, similar to the production cost examples provided.

It seems there is a typo in the initial fraction of ribbon used per bow, as it is not provided in the question. Assuming the fraction provided is the one we would work with, let's say it takes [tex]\( x \)[/tex] of a ribbon to make one hair bow. To find out how much ribbon is needed to make 9 bows, we multiply [tex]\( x \)[/tex] by 9. Therefore, the total amount of ribbon required for 9 bows would be [tex]\( 9x \)[/tex].

Going by the example information given, if we compare it with the cost of manufacturing goods, we can draw on the parallel of calculating the cost to produce multiple items. For example, if pants finishing costs 49 cents for 7 pairs, and we want to calculate for 9 pairs, we would set up a proportion or use unit rate to find the answer. Though this example doesn't directly relate to the ribbon question, it illustrates the process of scaling up a unit quantity to a larger quantity, which is a common mathematical operation in both scenarios.

Answer:

D. multiply the previous value by 3

Step-by-step explanation:

The pattern of values as the exponents increase is

1/3, 1, 3, 9

Comparing 1/3 to 1, we either add 2/3 or multiply by 3.

Comparing 1 to 3, we either add 2 or multiply by 3.

Comparing 3 to 9, we either add 6 or multiply by 3.

The constant in this pattern is multiplication by 3.

The value of rate of change in the equation [tex]T(d)=37.69d+60.22[/tex] is 37.69.

Step-by-step explanation:

Given the equation that models the total cost(T) is:

[tex]T(d)=37.69d+60.22[/tex]  where d is the drink you purchase.

To determine the rate of change:

1. An equation must be into the Slope-intercept form (y=mx+b).

2. m is the slope (rate of change) of the linear function.

3. b is the y-intercept of the linear function (y- intercept is where the line crosses the y-axis).

Since, the given equation is in the linear form i.e, [tex]T(d)=37.69d+60.22[/tex]

The rate of change(m) of the given equation is, 37.69.

the original price of the sofa was 727.26

Step 1. Simplify brackets

-3x + 7 -4(2x - 6) -12 > 7

Step 2. Cancel 7 on both sides

-3x -4(2x - 6) -12 > 0

Step 3. Expand

-3x - 8x + 24 - 12 > 0

Step 4. Simplify -3x - 8x + 24 - 12 to -11x + 12

-11x + 12 > 0

Step 5. Subtract 12 from both sides

-11x > -12

Step 6. Divide both sides by -11

x < -12/-11

Step 7. Two negatives make a positive

x < 12/11

The answer is x < 12/11.

Answer:

$5

Explanation:

Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.

Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.

   660=x50

From here, you have to solve for x. So cross multiply, and then simplify.

   60x=50⋅6

   60x60=50⋅6/60

   60x60=50⋅6/60

   x=5⋅6/6

   x=5

So the answer is $5.

Jerry earned about $76.98 for the day.

Jerry walked a dog from 6:40 am to 7:30 pm. To calculate how much he earned, we need to determine the total number of hours he worked.

First, we convert the end time into military time, which is 19:30.

Subtract the start time, 6:40, from the end time, 19:30.

Calculation:

Now, we use the rate of $6 per hour to calculate his earnings:

Earnings = Total hours * Rate per hour

Earnings = 12.83 hours * $6/hour = $76.98

Since Jerry worked a fraction of an hour, we included the approximate earnings up to two decimal places.

So, Jerry earned about $76.98 for the day.

There are 259 kids on all 7 buses.

Add 16 to 1 9/16 that will then be 25/16 then you divide 5 from 25 that equals 5 so that is your answer

the product is always the same:

1440

The smallest possible product using the digits 2, 3, 5, 6, 8 is 1440.

To do this, we’ll arrange the digits in ascending order:

2 < 3 < 5 < 6 < 8

Hence, the smallest number formed using these digits is 23568.

Now let’s calculate the product:

2*3*5*6*8 = 1440

So, the product is always the same: 1440.

Whether you arrange the digits in ascending or descending order, the product remains unchanged because multiplication is commutative (i.e., the order of multiplication doesn’t matter)

It will take 4 minutes to rotate 1º because 15 divided by 15 is one (to get 1º) and 60 (1 hour) divided by 15 is 4.

This is placed at the thousandth place
