Since the product is negative, only one of the factors in the pair is negative.

If it's -10 Fahrenheit in Minneapolis and a cold front drops the temperature by 40 degrees, the new temperature would be -50 Fahrenheit.

If the temperature is -10 Fahrenheit in Minneapolis, and a cold front drops the temperature by 40.0 Fahrenheit degrees, we need to calculate the new temperature. This would mean subtracting 40 degrees from the current temperature of -10 degrees.

Starting with -10, we subtract 40 degrees:
-10 − 40 = -50

Therefore, the value that could represent the temperature in Minneapolis after the cold front is -50 Fahrenheit.

To find out when Jordan and Jake will earn the same amount, we need to set their earnings equations equal to each other and solve for the number of hours worked. The resulting value will be the number of hours at which they both earn the same amount.

To determine the number of hours it will take for Jordan and Jake to earn the same amount of money, we need to solve an equation that sets their earnings equal to each other.

For Jordan, her earnings (EJ) are calculated as $9 per hour plus a $10 allowance. So, we write this as an equation:

EJ = 9h + 10.

Similarly, for Jake, his earnings (EJk) are calculated as $6.50 per hour plus a $15 allowance. So, his earning equation is given by:

EJk = 6.5h + 15.

To find when they earn the same, we set the two equations equal to each other:

9h + 10 = 6.5h + 15

By simplifying the equation, it results in 'h', which represents the number of hours needed for Jordan and Jake to earn the same amount of money.

Heather's weekly sales must be $7500 in order to earn $375.00 in weekly salary.

Therefore,

Commission / commission rate = sale

Commission = $ 375.00 in a week

Commission rate = 5%

∴ 0.05

Then simplifying we get,

⇒ 375/0.05

= 7,500

Hence, Heather's weekly sales have to be $7500 to earn $375.00 in a weekly salary.

The pairs of numbers that multiply to give 44 are (1, 44), (2, 22), and (4, 11).

Given that we need to determine what times what equals 44,

We can look at the factors of 44 to discover two integers that multiply to equal 44.

The 44 factors are:

1, 2, 4, 11, 22, 44

As a result, the following alternative pairs of numbers can be multiplied to create 44:

1 × 44 = 44

2 × 22 = 44

4 × 11 = 44

Therefore, (1, 44), (2, 22), and (4, 11) are the pairs of numbers that multiply to generate 44.

To write a word problem where the starting number is in the hundreds and the answer is 4 tickets left over, create a scenario where someone buys tickets for a concert and some are left over.

To write a word problem where the starting number is in the hundreds and the answer is 4 tickets left over, we can create a scenario where someone buys tickets for a concert and some are left over. For example:

Sarah bought 350 tickets for a concert. She gave 120 tickets to her friends and sold 225 tickets. How many tickets does she have left?

To solve this problem, we subtract the number of tickets Sarah gave to her friends and sold from the starting number:

Starting number - Tickets given to friends - Tickets sold = Tickets left over

350 - 120 - 225 = 5

Sarah has 5 tickets left over.

Answer:

12.115 ounces of batter

Step-by-step explanation:

Isaac made 2 quarts and 1 cup of cupcake batter.

We will convert the amount into ounces

1 quart = 32 ounces

2 quarts = 32 × 2 = 64 ounces

1 cup = 8.115 ounces

∴ 2 quarts and 1 cup = 64 + 8.115 = 72.115 ounces

To make one cupcake Isaac needs the amount of batter = 6 ounces

He is making 10 cupcakes, so he would be needed = 10 × 6 = 60 ounces

He has 72.115 ounces of batter and he would be needed 60 ounces

The left over batter = 72.115 - 60 = 12.115 ounces.

12.115 ounces batter would be left over.

The total number of rows needed to reserve in the theater for 146 students and 5 teachers, assuming that each row has 8 seats, is 19 rows.

To determine the number of rows needed to reserve in the theater for 146 students, 5 teachers, and its chaperones, we first need to calculate the total number of individuals attending. This is done by simply adding the students and teachers:

146 students + 5 teachers = 151 people

Next, we divide the total number of people by the number of seats in each row to find the number of rows to reserve. Since each row has 8 seats:

151 people \/ 8 seats per row = 18.875 rows

Since you cannot reserve a fraction of a row, we need to round up to ensure there is a seat for everyone. Therefore, we will need to reserve 19 rows in total.

Two consecutive positive integers that sum to 71, a simple equation can be used leading to the solution that the integers are 35 and 36.

Tasked with finding two consecutive positive integers whose sum is 71. To solve this, let's represent the smaller integer as n, which means the next consecutive integer is n+1. According to the riddle, the sum of these two integers is 71:

n + (n + 1) = 71

Solving this equation:

2n + 1 = 71

2n = 71 - 1

2n = 70

n = 35

The smaller integer is 35, and the next consecutive integer is 36. Therefore, the two consecutive positive integers are 35 and 36.
