Which of the following would earn the same amount of interest as a​ $600 principal with​ 2.5% interest for 6​ years?

Answers

Final answer:

To earn the same amount of simple interest as $600 with 2.5% interest over six years ($90), another investment combination that would yield the same interest amount is $1,000 at 3% interest for 3 years.

Explanation:

The student is asking which investment would earn the same amount of simple interest as a principal of $600 with 2.5% interest over 6 years. The formula for calculating simple interest is Interest = Principal  imes Rate  imes Time. For the given principal of $600 with 2.5% interest over 6 years, the interest earned would be:

Interest = $600  imes 0.025  imes 6

Interest = $90

To find another investment with the same interest earned, one must find a principal, rate, and time that satisfy the equation:

Interest Earned = New Principal  imes New Rate  imes New Time = $90

An example would be a principal of $1,000 with 3% interest for 3 years:

Interest Earned = $1,000  imes 0.03  imes 3

Interest Earned = $90

This indicates that both investments would earn the same amount of interest over their respective periods.

A recipe calls for 40 ounces of meat.How many pounds of meat does the recipe require?

Answers

Answer: 40 ounces=2.5 pounds


Step-by-step explanation:

Since 1 pound=16 ounces. You have to see how many times 16 goes into 40, it goes in forty 2 times with 8 left over so that means we need  decimal, since 8 is half of 16 the answer is 2.5.


Final answer:

To convert 40 ounces of meat to pounds, divide by the unit equivalence of 16 ounces per pound, resulting in 2.5 pounds of meat needed for the recipe.

Explanation:

The student is asking how many pounds are equivalent to 40 ounces of meat. To find the answer, you will need to know the unit equivalence between ounces and pounds.

The unit equivalence is 1 pound = 16 ounces. Therefore, to convert ounces to pounds, you divide the number of ounces by the unit equivalence.

Converting 40 ounces to pounds:

Start with the given amount in ounces: 40 ounces.Use the unit equivalence: 1 pound = 16 ounces.Divide 40 ounces by 16 ounces per pound to find the number of pounds.

40 ounces ÷ 16 ounces/pound = 2.5 pounds

So, the recipe requires 2.5 pounds of meat.

Anyone know? Will mark brainliest if correct!

Answers

The answer is A. g(x).

Here's why:

f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.

g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).

Key points:

The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.

g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).

Therefore, g(x) has the largest maximum y-value among the two functions.

there are 11 regular players and 5 substitute players on a soccer team how many players are on 15 soccer teams ??

Answers

Answer:

225 players (including the substitutes)

Step-by-step explanation:

11 regular player and 4 substitutes makes 15 team members per team.

15 players on each team times 15 teams gives you 225 players in total.


Final answer:

The total number of players on 15 soccer teams can be calculated by multiplying the total number of players (including regular and substitute) on one team (16 players) by the number of teams (15), which equals 240 players.

Explanation:

The subject of this question is Mathematics, and it's referencing a concept of multiplication in a real-world context. To determine the total number of players on 15 soccer teams, you consider that each team is composed of 11 regular players and 5 substitutes. So, the total number of players on one team is 16 (11 regular players + 5 substitutes).

To find out the number of players on 15 teams, you multiply the number of players on one team by 15. That is, 16 players * 15 teams = 240 players. So, there are 240 players on 15 soccer teams.

Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )

Answers

Answer:

she can watch 3.5 hours this week.

Step-by-step explanation:

Julia is allowed to watch no more than 5 hours of television a week.

Let x be the number of hours she can watch per week

number of hours not more than 5 hours

so x<=5

She already watched 1.5 hours. so inequality becomes

x+ 1.5 <= 5

Now we solve for x

subtract 1.5 on both sides

x + 1.5 < = 5 - 1.5

x < = 3.5

So, she can watch 3.5 hours this week.

Write the expression 6a-2(a-1) in simplest form

Answers

Final answer:

To simplify the expression 6a - 2(a - 1), distribute the -2 across the terms inside the parentheses, and then combine like terms to get the simplest form, which is 4a + 2.

Explanation:

To simplify the expression 6a - 2(a - 1), you need to distribute the -2 across the terms inside the parentheses and then combine like terms. Here's the process step by step:

Distribute the -2 to both a and -1 inside the parentheses: -2 x a gives us -2a, and -2 x -1 gives us +2.Write out the new expression without parentheses: 6a - 2a + 2.Combine like terms by subtracting -2a from 6a, which results in 4a.Add the constant term 2 to get the final simplified expression: 4a + 2.

The simplest form of the expression is 4a + 2.

A recursive rule for an arithmetic sequence is a1=-2; an=an-1 -9

What is an explicit rule for this sequence?

Answers

Final answer:

The explicit rule for the given arithmetic sequence is an = -2 + (n - 1) * (-9)

Explanation:

An arithmetic sequence is a sequence of numbers in which each term is found by adding a common difference to the previous term. In this case, the recursive rule for the arithmetic sequence is given as a1 = -2 and an = an-1 - 9.

To find the explicit rule for this sequence, we need to find a formula that directly calculates the nth term of the sequence. We can do this by examining the pattern in the sequence:

First term: a1 = -2Second term: a2 = a1 - 9 = -2 - 9 = -11Third term: a3 = a2 - 9 = -11 - 9 = -20Fourth term: a4 = a3 - 9 = -20 - 9 = -29...

From the pattern, we can see that each term is obtained by subtracting 9 from the previous term. So, the explicit rule for this arithmetic sequence is given by:

an = a1 + (n - 1) * d

where a1 is the first term, n is the term number, and d is the common difference. Plugging in the values, we have:

an = -2 + (n - 1) * (-9)

Simplifying this equation gives the explicit rule for the sequence.

Final answer:

The explicit rule for the arithmetic sequence is an = -2 + (n-1)(-9).

Explanation:

An explicit rule for an arithmetic sequence is given by the formula:

an = a1 + (n-1)d

Where:

an is the nth term of the sequence

a1 is the first term of the sequence

n is the position of the term in the sequence

d is the common difference between consecutive terms

In this case, the first term (a1) is -2 and the common difference (d) is -9. Therefore, the explicit rule for this sequence is:

an = -2 + (n-1)(-9)

Which value is the same as 2 tenths?

Answers

One fifth

.........
Final answer:

2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.

Explanation:

In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.

Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

Answers

Final answer:

To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.

Explanation:

To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:

240g plain flour : 2 eggs : 600ml milk

To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:

240g / x = 12 / 1

Cross multiplying, we get:

x = (240g * 1) / 12

x = 20g

Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.
