Final answer:

The algebraic expression for 'Double the sum of 2 and x increased by one-half x squared' is 2(2 + x) + (1/2)x².

Explanation:

To translate the phrase 'Double the sum of 2 and x increased by one-half x squared' into an algebraic expression, we break it down into parts:

The sum of 2 and x is given by the expression (2 + x).

Double this sum can be written as 2(2 + x).

One-half x squared is written as (1/2)x².

Increasing the doubled sum by one-half x squared means adding (1/2)x² to it.

Therefore, the complete algebraic expression is 2(2 + x) + (1/2)x².

Regarding the concept of squaring of exponentials, remember that when you square a term like x², you are effectively raising x to the power of 4 because the exponents are multiplied.

Answer: The required expression will be

[tex]\frac{6000-p}{24}[/tex]

Step-by-step explanation:

Since we have given that

Amount that Liam has = $250

Amount that he and his classmates spent on  present for their teacher =$p

Number of students in which $p will split = 24

According to question,

Amount that left to Liam is given by

[tex]250-\frac{p}{24}\\\\=\frac{6000-p}{24}[/tex]

Hence, the required expression will be

[tex]\frac{6000-p}{24}[/tex]

To calculate how much money Liam has left, subtract the cost of the present from his initial amount of money. The expression that represents this is $250 - ($p/24).

To find out how much money Liam has left after buying the present, we need to subtract the cost of the present from the initial amount of money Liam had. The cost of the present can be calculated by dividing the total cost by the number of classmates, which is 24. So, the cost of the present is $p/24. Therefore, the expression that represents how much money Liam has left is:

$250 - ($p/24)

Answer:

Weight of parcel to the nearest whole kilogram = 6 kg

Explanation:

 Weight of parcel = 12 lbs 8 oz

 1lb = 16 oz  also we have 1lb = 454 g

 Weight of parcel = 12 lbs 8 oz = 12 + (8/16) lbs = 12.5 lbs

  Weight of parcel in g = 12.5*454 = 5675 g

  Weight of parcel = 5675 g = 5.675 kg

  Weight of parcel to the nearest whole kilogram = 6 kg

To convert the weight of a 12 lbs 8 oz parcel to kilograms, you first convert the weight to ounces, then to grams, and finally to kilograms. The final conversion results in a weight of approximately 5.67 kg, which is rounded to the nearest whole number as 6 kg.

The weight of a parcel can be converted from pounds and ounces to kilograms using a two-step process. First, you need to convert the entire weight into ounces, and then convert that result to grams. Finally, convert grams to kilograms.

To convert 12 lbs 8 oz to ounces, calculate as follows: (12 lbs × 16 oz/lb) + 8 oz. This equals 192 oz + 8 oz = 200 oz.

To convert ounces to grams: 200 oz × 28.35 g/oz gives 5670 g.

To find the weight in kilograms, divide the number of grams by 1000, because 1 kg = 1000 g. So, 5670 g ÷ 1000 g/kg gives 5.67 kg. To the nearest whole kilogram, the package weighs 6 kg.

To determine how many different boy-girl dates can be arranged from 15 girls and 14 boys, multiply the number of boys by the number of girls, leading to 210 different boy-girl dates.

The question asks how many different boy-girl dates can be arranged if an eighth-grade class has 15 girls and 14 boys. To solve this, we can use the concept of multiplication principle in combinations. Each boy in the class has the option to date any of the 15 girls. This means each of the 14 boys has 15 choices for who to date. Therefore, to calculate the total number of distinct boy-girl date arrangements, we multiply the number of boys by the number of girls they can potentially date.

Calculating: 14 boys × 15 girls = 210 different boy-girl dates can be arranged.

This simple calculation shows how combinations are used to determine possibilities in everyday scenarios, reinforcing the importance of basic arithmetic skills in problem-solving.

The inequality to describe S, the weight of the special sundae in kilograms, at Ping's Ice Cream Palace is S > 2, indicating the sundae weighs more than 2 kilograms.

The question involves creating an inequality to describe the weight of a special sundae, S, at Ping's Ice Cream Palace. Since the sundae contains over 2 kilograms of ice cream, this means the weight of the sundae is greater than 2 kilograms. However, since there can be any number of toppings, there is technically no upper limit to the weight. Therefore, the inequality to describe S, the weight of the special sundae in kilograms, would be:

S > 2

This inequality indicates that the weight of the sundae is strictly more than 2 kilograms, considering the ice cream and any added toppings.

Rounding the world's largest aloha shirt measurement, 4.26 meters, results in 5 to the nearest ones place and 4.2 to the nearest tenths place.

To round the measurement of the world's largest aloha shirt to the nearest ones place, we look at the decimal part of the number 4.26. Since the digit after the decimal is 6 (which is 5 or higher), we round up the number 4 to 5. Therefore, when rounded to the nearest ones place, 4.26 becomes 5.

To round to the nearest tenths place, we only need to consider the first digit after the decimal point. In this case, that digit is 2, which means there is no need to round up or down; the tens digit stays the same. So, when rounded to the nearest tenths place, 4.26 remains 4.2.

Answer:

8

Step-by-step explanation:

There are 42 people who had breakfast.  Each person had either egg or pancake or both.

Of these only eggs were 2/3 and both were 2/3

Hence the remaining ate only pancakes

i.e. portion of persons who ate pancakes = 1-(1/7+2/3)

= 4/21

Total no of people in the restaurant = 42

Of those people who ate eggs only= 1/7 (42) = 6

No of persons who ate both pancakes and eggs = 2/3(42) = 28

Hence no of persons who ate only pancakes =42-(6+28) = 8

95.20-50=  45.20

45.20/.40= 113

they went 113 minutes over their plan

The family exceeded their plan by 113 minutes.

To find out how much time the family exceeded their plan, we need to subtract the included minutes from the total minutes used and then divide by the overage rate. The included minutes in the plan are 900, and the cost per minute over the limit is $0.40. The total amount paid by the family is $95.20. Let's calculate:

Total minutes used = Total amount paid - Cost of the plan = $95.20 - $50 = $45.20
Exceeded minutes = Total minutes used - Included minutes = $45.20 / $0.40 = 113 minutes

The family exceeded their plan by 113 minutes.

Final answer:

After comparing the fractions of the chocolate cake (5/12) and the marble cake (1/2 or 6/12) eaten by the family, it's clear that they ate more marble cake as 6/12 is greater than 5/12.

Explanation:

Jared cut a chocolate cake into 12 equal parts and a marble cake into 6 equal parts. After his family ate 5 slices of chocolate cake and 3 slices of marble cake, we want to determine which type of cake they ate more of. To compare the quantities directly, we consider the size of each individual slice. A chocolate cake is cut into 12 pieces, so each slice represents 1/12 of the full cake. The marble cake is cut into 6 pieces, meaning each slice is 1/6 of the entire cake. Therefore, when the family ate 5 slices of chocolate cake, they consumed 5/12 of the chocolate cake, and consuming 3 slices of marble cake equates to 3/6, or 1/2 of the marble cake.

To compare these fractions, we can notice that 1/2 is equivalent to 6/12 when converted to have a common denominator. Comparing 5/12 and 6/12, it is clear that 6/12 is greater. Thus, the family ate more marble cake than chocolate cake.

Answer:

Step-by-step explanation:

Kendra buys  x pounds lettuce.

If lettuce costs $2.25 per pound.

Then for x pounds of lettuce,

cost=2.25x

Kendra buys  y pounds tomatoes.

If tomatoes costs $2.65 per pound.

Then for y pounds of tomatoes,

cost=2.65y

So, total cost=2.25x+2.65y

Now, this total cost will be at least  $8

So, the inequality is-

[tex]2.25x+2.65y\geq8[/tex]

The problem can be represented by the inequality [tex]2.25x + 2.65y \geq 8[/tex] where x is the number of pounds of lettuce Kendra buys and y is the number of pounds of tomatoes she buys. The total cost of the vegetables equals or exceeds $8.

In this situation of buying lettuce and tomatoes, the cost of lettuce per pound is $2.25 and the cost of tomatoes per pound is $2.65. Kendra spends at least $8 on lettuce and tomatoes. Let x represent the number of pounds of lettuce that Kendra buys and let y represent the number of pounds of tomatoes that she buys. Understanding the problem, the inequality that represents this situation is

[tex]2.25x + 2.65y \geq 8[/tex]. This is because each pound of lettuce ('x') is multiplied by its cost, and each pound of tomatoes ('y') is multiplied by its cost. If Kendra spends at least $8, then the total cost equals or exceeds $8.
