To get -18, we can use the factors
2 times -9 = 18How to fill the blanksTo find two numbers that multiply to give -18, we need to consider pairs of factors of -18. The factors of -18 are:
1 and -18
2 and -9
3 and -6
So, the pairs of numbers that multiply to give -18 are:
1 * -18 = -18
2 * -9 = -18
3 * -6 = -18
Therefore, -18 can be expressed as the product of various combinations of these pairs, such as (-2) * 9, (-3) * 6, and so on.

Diego Rollins is paid $10.20 an hour for a regular 40-hour week at the
driving range. His overtime rate is 15 times his regular hourly rate.
This week he worked his regular 40 hours plus 8 hours of overtime.
Vhat is Diego's total pay?
Answer:
$1632
Step-by-step explanation:
Hourly pay for Diego = $10.20
Weekly hours = 40 Hours
Basic earning = 10.20 × 40 = $408
Overtime pay = 15 × Hourly rate = 15 × 10.20 = $153
Total overtime = 8 hours
Overtime earning = 153 × 8 = 1224
Total earning for the week = 408 + 1224 = $1632

A crayon company makes 87,491 blue crayons, 36,262 red crayons, and 25,063 gray crayons. how many more blue crayons are made than red and gray crayons combined?
Answer:
26 166
Step-by-step explanation:
Blue = 87 491
Red = 36 262

-(Red + green) = - 61 325
Blue - (red + green) = 26 166
The company makes 26 166 more blue crayons than red and green combines.
Lainey bought a set of 20 markers for $6
Final answer:
To find the unit price of markers in a set, divide the total cost by the number of markers to find that each marker costs $0.30 when 20 are purchased for $6.
Explanation:
Lainey's purchase of a set of 20 markers for $6 can be used to illustrate a simple mathematical concept known as unit price, which is the cost per individual item when items are sold in a set or batch. To calculate the unit price, you divide the total cost by the number of items in the set. Here's how you can do this calculation:
Determine the total cost of the set of markers, which is $6.
Count the number of markers in the set, which is 20.
Divide the total cost by the number of markers to find the unit price: $6 ÷ 20 = $0.30 per marker.
Therefore, the cost of each individual marker from the set is $0.30. Starting small, such as with markers, pencils, sharpeners, and erasers, and gradually adding other items like construction paper or magnets, are good practices in both purchasing supplies and understanding incremental costs in financial literacy.

If n represents a number then write an expression for a number that’s twice than n
Final answer:
An expression for a number that's twice another number represented by n is written as 2n.
Explanation:
If n represents a number, then the expression for a number that's twice n can be written as 2n. This stems from the definition that multiplying a number by 2 effectively doubles it. To better understand this concept, consider the next statement, N=N*2, which tells us that the new value of N is twice the original value. So, if we substitute N with n, we can express a number that's twice n as 2n.

When measuring the length a and the width b of a rectangle, it was found that 5.4< a< 5.5 and 3.6< b< 3.7 (in centimeters). Find the possible values of: the perimeter of the rectangle
Answer:
The possible values of the perimeter of the rectangle is between 18 and
18.4 cm ⇒ [18 < perimeter of rectangle < 18.4] cm
Step-by-step explanation:
* Lets explain how to solve the problem
- The perimeter of any quadrilateral is the sum of the length of its
four sides
- The rectangle is a quadrilateral with each two opposite sides are
equal in lengths, then its perimeter = 2l + 2w, where l, w are its
length and width
∵ The the length of the rectangle is a
∵ 5.4 < a < 5.5 cm
∵ The perimeter of the rectangle = 2a + 2b
- Lets multiply the inequality by 2
∴ 5.4 × 2 < a × 2 < 5.5 × 2
∴ 10.8 < 2a < 11 ⇒ (1)
∵ The width of the rectangle is b
∵ 3.6 < b < 3.7 cm
- Lets multiply the inequality by 2
∴ 3.6 × 2 < b × 2 < 3.7 × 2
∴ 7.2 < 2b < 7.4 ⇒ (2)
- Add inequalities (1) and (2)
∵ 10.8 < 2a < 11
+ 7.2 < 2b < 7.4
∴ 18 < 2a + 2b < 18.4
∵ 2a + 2b represents the perimeter of the rectangle
∴ The possible values of the perimeter of the rectangle is between
18 and 18.4 cm ⇒ [18 < perimeter of rectangle < 18.4] cm

The numbers of calories per serving for various snakes foods are listed below.
Corn chips: 230 calories
Popcorn: 25 calories
Potato chips: 115 calories
Pretzels: 62 calories
What is the mean number of calories per serving for these foods?
A.) 88.5 cal.
B.)108 cal.
C.)230 cal.
D.)432 cal.
Answer:
B. 108 calories
Step-by-step explanation:
The mean number of a data set is
[tex]\text{Mean}=\dfrac{\text{The sum of all calories in products}}{\text{The number of products}}[/tex]
Corn chips: 230 calories
Popcorn: 25 calories
Potato chips: 115 calories
Pretzels: 62 calories
Thus,
The sum of all calories [tex]=230+25+115+62=432[/tex]
The number of productrs = 4
The mean number of calories [tex]=\dfrac{432}{4}=108[/tex]
Sven is trying to find the maximum amount of time he can spend practicing the five scales of piano music he is supposed to be working on. He has 60 minutes to practice piano and would like to spend at least 35 minutes playing songs instead of practicing scales. So, Sven sets up the following inequality, where t is the number of minutes he spends on each scale, and solves it.
Answer:
He must spend no more that 25 minutes practising scales.
Step-by-step explanation:
5t + 35 ≤ 60
5t ≤ 25
t ≤ 5.
So the maximum time for practising the scales is 5*5 = 25 minutes.
Answer:
Sven should spend 5 minutes or less on each scale. Maximum times is 25 minutes.
Step-by-step explanation:
Total time to practice piano = 60 minutes
He would like to spend at least 35 minutes playing songs instead of practicing scales.
Let t is the number of minutes he spends on each scale.
The time spend on 5 scales = 5t
Time for playing songs = 60 - 5t
It is given that he would like to spend at least 35 minutes playing songs instead of practicing scales. It means time for playing songs is greater than or equal to 35.
[tex]60-5t\geq 35[/tex]
Subtract 60 from both sides.
[tex]60-5t-60\geq 35-60[/tex]
[tex]-5t\geq -25[/tex]
Divide both sides by -5. If an inequality is divided or multiplied by a negative number, then the sign of inequality is changed.
[tex]t\leq 5[/tex]
Sven should spend 5 minutes or less on each scale.
The maximum value of t is 5, so the maximum time spend on practicing scales is
[tex]\text{Maximum time}=5t\Rightarrow 5(5)=25[/tex]
Therefore, the maximum time is 25 minutes.

16. A 20.25-gallon gasoline tank is 3/5 full. How many gallons
will it take to fill the tank?
To fill the tank, multiply 2/5 by the tank's capacity of 20.25 gallons.
Explanation:To find the number of gallons it will take to fill the tank, we need to determine how much more fuel is needed to make the tank full. We can do this by subtracting the current amount of fuel in the tank from its full capacity. The tank is 3/5 full, so the remaining amount of fuel needed to fill the tank is 2/5 of its capacity. Since the capacity of the tank is given as 20.25 gallons, we can calculate the number of gallons needed to fill the tank by multiplying 2/5 by 20.25:
2/5 * 20.25 = 8.1 gallons
Therefore, it will take 8.1 gallons to fill the tank.

In a department store, a $40 dress marked, "save 25%." what is the discount? what is the sales price of the dress?
Answer:
Discount = $10
Sales Price = $30
Step-by-step explanation:
Discount
= 25% of marked price
= 25% x $40
= (25/100) x 40
= $10
Sales price = Marked price - Discount = $40 - $10 = $30
The local football team won the championship several years ago, and since then, ticket
prices have been increasing $4 per year. The year they won the championship, tickets were
$20. Write an explicit formula for a sequence that will model ticket prices. What will the ticket
price be 10 years after that championship year?
Answer:
60$
Step-by-step explanation:
if 4$ is per year 20 ÷4 is 5, 5 years have passed and if 10 uears after the champion ship it will be 60 because 4 × 10 is 40 plus the 5 years since it was 20 therefore 20+40 =60
The explicit formula for the ticket price after n years is T(n) = 20 + 4n. Plugging in 10 for n, we find that the price 10 years after the championship will be $60.
Explanation:The question asks us to create an explicit formula to model the increasing price of football tickets after the local team won a championship. If tickets were originally $20 and the price increases by $4 each year, we can use the formula T(n) = 20 + 4n to represent the price of football tickets after n years.
For 10 years after the championship year, we plug 10 into our equation for n: T(10) = 20 + (4 \times 10) = 20 + 40 = $60. Thus, the ticket price will be $60, 10 years after the championship year.
