What is defined as the product?The term product refers to the solution to a multiplication troubles.Multiplication is also known as repeated addition because the multiplication problem indicates that you have a particular number of groups about something, each of which contains a specific number.The commutative property states that when two numbers have been multiplied together, this same product remains the same regardless of how they are written.When three or even more numbers are magnified together, the product is the same no matter which two are multiplied first.For the given conditions in the question.
Let the existing number be 'x'.
3 times the number means do the multiplication of number by 3.
= 3x.
3 times as many to potential members than to existing members.
Thus,
3x = 192
x = 192/3
x = 64

Tristian says that 9.32 is a rational number Barry says that 9.32 is a terminating decimal who is correct
Tristian and Barry both are correct as 9,32 is a rational and terminating decimal.
A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
A terminating decimal is a decimal number with a finite number of digits after the decimal point. The repeating decimal 5.6500000000... can be used to represent a terminating decimal like 5.65, however, when it is zero, the value is typically referred to as terminating.
A decimal number having a limited number of digits following the decimal point is referred to as a terminating decimal. Therefore, all decimal numbers that terminate are rational numbers.
Hence both are correct.

Point D(−1, 5) is reflected across the x-axis. Which statements about D′ are true? Select each correct answer. Responses The y-coordinate is 5. The , y, -coordinate is 5. The y-coordinate is −5. The , y, -coordinate is , negative 5, . The x-coordinate is −1. The , x, -coordinate is , negative 1, . The x-coordinate is 1.
The correct option is (A) The y-coordinate is -5. If point D(-1, 5) is reflected across the x-axis then the coordinates of D’ are (-1, -5).
What does it mean to reflect coordinates?Geometry. The x-coordinate remains constant when a point is reflected across the x-axis, but the y-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the x-axis as (x, -y).
Determine the location of the mirror line before reflecting an object on a coordinate plane. Simply multiply the coordinate of the point by -1 to reflect over the axis. Use the symbols. Simply multiply the coordinate of the point by -1 to reflect over the axis.
Given coordinates of D= (-1, 5)
While reflecting any points across the x-axis with coordinates as (x, y) becomes, (x, -y). i.e sign of y-coordinate changes.
The rule is: (x, y) arrow (x, -y)
Applying so, after reflecting point D, its reflection D' will have coordinates as (-1, -5)
Therefore, the y-coordinate is -5.

Greg is purchasing ink cartridges for his computer. Each ink cartridge costs $35.99 and comes with a $10 rebate. How much will Greg pay for one ink cartridge after the rebate?
*Rebate is a refund of part of the amount paid for an item
Greg will pay $25.99 for one ink cartridge after the rebate.
As stated in the question, rebate is the refund that customer receives. It is part of the amount paid. So, it can be easily deducted from the total amount. To find the payment amount, we will simply subtract rebate amount from ink cartridge cost.
Keep the values in mentioned relation to find the payment amount to be given by Greg for one ink cartridge.
Payment = 35.99 - 10
Performing subtraction to find the payment amount to be given by Greg
Payment = 25.99

Jodi wants to visit her extended family in barbados next summer, and the flight costs $450. how much does she need to save each month if she wants to buy the flight in exactly 9 months?
If Jodi wants to visit her extended family in Barbados next summer, and the flight costs $450, then she needs to save 50$ each month if she wants to buy the flight in exactly 9 months.
If the flight costs $450, then the amount of money Jodi needs to save each month can be determined by using division.
Division is one of the four basic operations of arithmetic and involves the separation into equal parts.
By dividing the cost of the flight by the number of months, the money Jodi needs to save each month can be calculated.
Considering x to be money Jodi needs to save each month,
x = flight cost / number of months
x = 450 / 9
x = 50
Hence, the money Jodi needs to save each month if she wants to buy the flight in 9 months is calculated to 50$.

c) The average speed during 20 the journey = 62.5 km/hr.
What is defined as the acceleration?Acceleration is the rate during which velocity changes over time, both in terms of speed and direction. A point or takes place in a straight line is sped up if it quickens or decelerates. Even if the speed is constant, motion on such a circle is accelerated because the direction is constantly changing.For the given question;
Every horizontal block is 1/8 hour = 7.5 minutes long.
Each vertical block has a speed of 10 km/hr:
The table drawn as per the data given in the table:
Time Velocity km/hr
0 Min ( 0 hr) ---> 0
15 Min (1/4 hr) --> 50
45 Min (3/4 hr) --> 50
60 MIn ( 1 hr) --> 100
90 Min ( 3/2 hr) ---> 100
120 Min ( 2hr) ---> 0
The formula for acceleration:
Part a: Acceleration = final velocity - initial velocity / final time - initial time
Acceleration in the first 15 minutes: (1/4 hr) = (50 - 0)/(1/4 - 0)
= 50/(1/4)
=200
Thus, acceleration in the first 15 minutes is 200 kmph.
Part b: Distance among two cities:
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)
= 25/4 + 25 + 75/4 + 50 + 25
= 125
The difference distance for two cities is 125 kilometers.
Part c: Average speed = distance/2
Average Travel Speed = 125/2 = 62.5 km/hr
Therefore,
a: Acceleration in the first 15 minutes = 200 km/h²
b: The distance between two cities is 125 kilometers.

Fuel efficiency of the cooper when driving at a speed of 75 mph = 29 miles per gallon
Fuel efficiency of the cooper when driving at a speed of 60 mph = 34 miles per gallon
Let y₁ = 75 mph, y₂ = 60 mph

Then the average rate of change of fuel efficiency = (y₂-y₁)/(x₂-x₁)
