What is Distributive Property?This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
Given:
We have 4(x+y)=4x+4y.
We have the Distributive Property
a x ( b+ c )= a x b + a x c
let x= 2 and y = 5
So, 4 (x+ y) = 4 (2+ 5)= 4(7) = 28
and, 4x+ 4y= 4(2)+ 4(5) = 8+ 20 = 28

What is Division?Division is one of the four basic operations of mathematics.
On performing the operation division, a number is divided into some number of equal parts.
The number which is being divided is called the dividend, the number which divides the dividend is called divisor and the number got when division is performed is called the quotient and the remaining number which has not divided is called the remainder.
Total number of students = 40
If there is 1 group, number of students in the group = 40/1 = 40
If there are 20 students in each group, then the number of groups = 40/20 = 2.
If there are 4 groups, then number of students in each group = 40/4 = 10.
Hence there will be 40 students in the group if there is 1 group. There are 2 groups if there will be 20 students in each group. There will be 10 students in each group if there are 4 groups.

The circumference of a circular field is 295.16 yards what is the radius of the field use 3.14 for pi and do not round your answer
The radius of circle is 47 yards.
What is Circumference of circle?The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle. It is typically expressed in units like cm or unit m.
The radius of the circle is considered when applying the formula to determine the circumference of the circle. Therefore, in order to calculate the circle's perimeter, we need to know the radius or diameter value.
Given:
Circumference of circle= 295.16 yards
Now,
circumference of circle= 2πr
295.16= 2 x 3.14 x r
295.16 = 6.28 x r
r = 295.16/ 6.28
r = 47 yards.
Hence, the radius of circle is 47 yards.

Is 0 prime odd or even prime or composite?
Answer:
0 is nor prime or composite
Step-by-step explanation:
The definition of a prime number is a positive integer that has exactly two positive divisors. Therefore, the simplest reason why 0 is not prime is that 0 is not a positive integer, and the axiom says that all whole numbers greater than 1 are either prime or composite.

It snowed 4 times during October. The snowfall amounts were 0.75 inches, 1.93 inches, 4.73 inches, and 2.33 inches. What was the total snowfall for October?
The total snowfall for October was 9.74 inches. Adding the snowfall amounts of 0.75, 1.93, 4.73, and 2.33 inches resulted in this sum.
Let's break down the calculation step-by-step:
Identify the given snowfall amounts for October:
The snowfall amounts are 0.75 inches, 1.93 inches, 4.73 inches, and 2.33 inches.
Add up the snowfall amounts to find the total:
Total snowfall = 0.75 inches + 1.93 inches + 4.73 inches + 2.33 inches.
Perform the addition
Total snowfall = 9.74 inches.
The total snowfall for October was 9.74 inches. This result is obtained by adding all four individual snowfall amounts together.
So, the calculation in step-by-step form is as follows:
0.75 + 1.93 + 4.73 + 2.33 = 9.74 inches.

A given cube with a volume of 1728 cubic inches:
Find the length of an edge:The sum of the first and third of three consecutive even integers is 128. find the three even integers.
Final answer:
The three even integers are 62, 64, and 66.
Explanation:
The sum of the first and third of three consecutive even integers is 128. To find the three even integers, we start by letting the first integer be x. Because the integers are consecutive even numbers, the second integer will be x + 2 and the third will be x + 4. The sum of the first and third integers gives us the equation:
x + (x + 4) = 128
Solving this equation:
Combine like terms: 2x + 4 = 128.
Subtract 4 from both sides: 2x = 124.
Divide both sides by 2: x = 62.
So, the first even integer is 62. Consequently, the second is 62 + 2 = 64, and the third is 62 + 4 = 66. Therefore, the three consecutive even integers are 62, 64, and 66.

Patty is, right now, 3 times as her brother Terry. in 10 years, the sum of their age will be 36. how old are they right now? show your work.
Patty is 12 years old, and Terry is 4 years old. After setting up an equation based on their ages now and in 10 years, we determine that Terry is 4, and since Patty is three times as old, she is 12.
The problem presented is a typical age-related algebraic question. To solve it, we can set up equations based on the information given. Let's define Patty's current age as 3T, where T represents Terry's current age. In 10 years, Patty will be 3T + 10 and Terry will be T + 10. According to the problem, the sum of their ages in 10 years will be 36. So, we can write the following equation:
3T + 10 + T + 10 = 36
Solving this equation:
Combine like terms: 4T + 20 = 36Subtract 20 from both sides of the equation: 4T = 16Divide both sides by 4 to find Terry's age: T = 4With Terry's age being 4, Patty's current age is 3 times Terry's age, which means Patty is 3 × 4 = 12 years old. So, Patty is 12 and Terry is 4 years old right now.
