Charlene, Mark, and Paul sold a combined total of 44 magazine subscriptions for their fundraiser.

In this problem, Charlene, Mark, and Paul collectively sold magazine subscriptions. We need to find the total number of subscriptions sold. We can do this using simple addition: Charlene sold 15 subscriptions, Mark sold 17 subscriptions, and Paul sold 12 subscriptions. Therefore, using s to represent total subscriptions, our equation would be: s = 15 (Charlene's sales) + 17 (Mark's sales) + 12 (Paul's sales). Summing the numbers, s = 44. Hence, they sold 44 subscriptions in total.

Answer:

44 hours

Step-by-step explanation:

Decreasing the people by a factor of 2 means we have 3 people

The job takes 6* 22 = 132 people hours

When we decrease the people, it will take more hours

132 people hours = 3 people * t hours

Divide each side by 3

132/3 = 3t/3

44 = t

It will take 44 hours

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.

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.

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.

Answer:

Reflection

Step-by-step explanation:

When we reflect a point on the x axis, the y coordinate changes its sign.

For example if a Point P has coordinates (x,y), it will be (x, -y) after reflection on the x axis.

A (-6,2) reflected on the x axis becomes A' (-6, -2)

B (-2,6) reflected on the x axis becomes B' (-2, -6)

C (-4,2) reflected on the x axis becomes C' (-4, -2)

So, the type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection on the x axis.

Step-by-step explanation:

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.

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.

Start by distributing:

-12(x+5) = (-12 * x) + (-12 * 5) = -12x - 60

144 = -12x - 60

Add 60 to both sides to start isolating your variable:

204 = -12x

Solve for x by dividing both sides by -12:

x = -17

Step-by-step explanation:

multiply -12 with x and 5, after you get the answer. subtract 60 on the left and right, after getting 84 divide it by -12 and the final answer will be -7

Step-by-step explanation:

Day 1) Monday --> 10 min.

Day 2) Tuesday --> 15 min.

Day 3) Wednesday --> 20 min.

Day 4 )Thursday --> 25 min.

Day 5) Friday --> 30 min.

Day 6) Saturday --> 35 min.

Day 7) Sunday --> 40 min.

Using the formula for the nth term in an arithmetic sequence, we find that Jasmine will practice for 40 minutes on the 7th day.

The problem can be solved by using arithmetic progression. The first term of this sequence is the amount of time Jasmine spent practicing on Monday, which is 10 minutes. The common difference is the amount of time she adds to her practice every day, which is 5 minutes. To find out how long she will practice on the 7th day, we can use the formula for the nth term in an arithmetic sequence: a + (n-1)d.

Plugging in our values, we find:
10 + (7-1)*5 = 10 + 30 = 40.

So, Jasmine will practice for 40 minutes on the 7th day.

To find the probability that the first grape candy chosen from the bag will be, at least, the third candy chosen overall, you multiply the probability that a candy is not grape (0.74) by itself (since we're considering two independent events, both candies not being grape). The answer is 0.5476.

The subject of this question is probability which is a branch of mathematics. You're looking to find the probability that the first grape candy drawn from a bag of Sandy's Sours will be, at least, the third candy chosen overall.

Given that 26% of the candies are grape, the probability that the first candy drawn is not grape is 1 - 0.26 = 0.74 (or 74%). Since we're looking for the first grape candy to be the third candy drawn or later, we need the first two candies to be not grape.

The probability that the first candy drawn is not grape is 0.74. Because each candy draw is an independent event (the result of one draw does not affect the results of any other draws), the probability that neither the first nor the second candy drawn is grape is 0.74 * 0.74 = 0.5476 (or 54.76%).

Answer:

A). $50.27

Step-by-step explanation:

Add $39.99 and -$10.28 to get $50.27

Final answer:

Julie withdrew $50.27 from her account, which can be calculated by adding her previous balance of $39.99 to the absolute value of her negative current balance, $10.28.

Explanation:

The question asks to determine how much was withdrawn from Julie's bank account, given that her balance went from $39.99 to -$10.28. To do this, we subtract the current balance from the previous balance. So the calculation is $39.99 - (-$10.28).

First, subtracting a negative is the same as adding its absolute value, so the equation can be rewritten as $39.99 + $10.28.

When these two values are added together, we get a total of $50.27. This means that Julie withdrew $50.27 from her account.

Therefore, the correct answer is A). $50.27.

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

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:

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)
