the oak tree at school was 34 feet tall then it grew 18 feet taller how tall is the oak tree now

Jan sold 8 magazines.

The question is a classic example of a system of linear equations in the context of solving word problems. To solve for the number of magazines Jan sold, we need to set up equations based on the information provided.

Let's denote the number of magazines Jan sold as J. According to the problem, Larry sold twice as many magazines as Jan did, which can be represented as 2J. Henry sold 8 more magazines than Jan, which can be represented as J + 8. Lastly, we are told that Larry and Henry sold the same number of magazines, meaning 2J is equal to J + 8.

To find the number of magazines Jan sold (J), we solve the equation:

2J = J + 8

2J - J = 8 (Subtract J from both sides)

J = 8

Thus, Jan sold 8 magazines.

Answer:

4

Step-by-step explanation:

Answer:

Every number from 51 all the way to 99.

Step-by-step explanation:

these are all not greater nor less than 50 and 100.

For girls: 12/30 = 4/10 = 2/5

For boys: 16/40 = 4/10 = 2/5

The ratios of the number of students on the team to the number of students trying out for both boys and girls are the same since 12/30 = 16/40...

The required quotient is 11 from the division of 22  by 2.

Given that,
To write a division problem that has two digit dividend and 1 digit divisor.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
let the two-digit dividend be 22 and the divisor be 2,

Final answer:

To find the approximate difference in the amount of wax needed to make a candle from each of these molds, we can calculate the volume of wax using the formula for the volume of a cylinder. The approximate differences in volume can be calculated by subtracting the volume of mold a) from the volumes of molds b), c), and d).

Explanation:

To find the approximate difference in the amount of wax needed to make a candle from each of these molds, we need to calculate the volume of wax required for each mold. The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.

Using the given values, we can calculate the volumes as follows:

Volume for mold a) = 3.14 × (sqrt(4.19/3.14))² × 1 = 7.98 cubic inches

Volume for mold b) = 3.14 × (sqrt(10.4/3.14))² × 1 = 35.58 cubic inches

Volume for mold c) = 3.14 × (sqrt(12.56/3.14))² × 1 = 50.24 cubic inches

Volume for mold d) = 3.14 × (sqrt(20.93/3.14))² × 1 = 111.51 cubic inches

The approximate differences in the amount of wax needed to make a candle from each of these molds are:

Approximate difference between mold a) and b) = 35.58 - 7.98 = 27.6 cubic inches

Approximate difference between mold a) and c) = 50.24 - 7.98 = 42.26 cubic inches

Approximate difference between mold a) and d) = 111.51 - 7.98 = 103.53 cubic inches

Mathematical properties like the Commutative Property and place value concepts can assist in simplified addition of decimals and whole numbers. Multiplying decimals by powers of ten can further ease such additions.

In the field of mathematics, properties can significantly aid in the process of adding whole numbers and decimals. One such property is the Commutative Property which states that the order in which numbers are added does not change the sum. For example, if you are adding 2.3 (decimal) + 4 (whole number), you would get the same result as 4 + 2.3.

Furthermore, you can leverage the concept of place value. This involves aligning the decimal points and adding digits from right to left to get the correct sum.

Lastly, multiplying by powers of ten can aid in the addition of whole numbers and decimals. When we multiply a decimal by a power of 10, we simply move the decimal point to the right by the same number of places as there are zeros in the power of 10. This can make additions easier. For instance, if we want to add 4 + 0.23, we could multiply 0.23 by 100 (a power of 10) to get 23, and then it's much straightforward to add 4 + 23. But we have to remember to divide by 100 at last to get the real answer: 4.23.

Choosing between a career as a brain surgeon and a novelist involves weighing the time commitment for education and training against immediate earning potential. Additionally, personal passion, societal impact, and job significance in relation to one's lifestyle should be considered. The value of a career isn't solely determined by financial gain or status.

Deciding between becoming a brain surgeon or a novelist involves considerations beyond immediate income. The hypothetical scenario emphasizes that both professions, in this case, pay $150,000 annually, with a key difference in time invested in education and training. A brain surgeon requires extensive education and does not begin earning until about age 35, whereas a shoe shiner, used metaphorically for immediate income jobs like novel writing, earns from age 16. This leads to an opportunity cost of $2.85 million over 19 years.

However, career decisions are not solely based on financial aspects. They require considering personal interests, skills, and societal needs. A brain surgeon's job is highly specialized, and few people possess the necessary skills, which warrants a high income as an incentive. Conversely, a novelist's path may allow more immediate creative expression and potentially earlier financial independence.

It's essential to consider long-term consequences and uncertainties in career choice. Your passion, societal impact, and desired lifestyle must all shape your decision. Moreover, the intrinsic value of different professions cannot be solely quantified by income or prestige. Jobs like brain surgery or coal mining are both critical, and their importance is context-dependent.

Answer:

The domain is the temperature

Step-by-step explanation:

The domain of a function can be seen as the set of all possible independent values or variables which will make the function "work", and will output real values for the independent variable.

In the question above, what's been recorded daily is the temperature.

Hence, it serves as the independent variable as its variation does not depend on that of another.

So, temperature is the domain for the function above
