what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

So, we have
-3f(x - 1)
When x = 0, we have
y = -3f(0 - 1)
This gives
y = -3f(-1)
From the table, we have
y = -3 * 21

-8/9 + (-2)/57
find the absolute value of the following rational number
The absolute value of the Rational number -474/513 is 474/513.
To find the sum of the rational numbers -8/9 and -2/57, you need to have a common denominator. The least common multiple (LCM) of 9 and 57 is 513. So, you can rewrite the fractions with a common denominator:
-8/9 = (-8/9) * (57/57) = -456/513
-2/57 = (-2/57) * (9/9) = -18/513
Now, you can add the fractions:
-456/513 + (-18/513) = (-456 - 18)/513 = -474/513
To find the absolute value of the rational number -474/513, you simply ignore the negative sign and take the value as positive:
| -474/513 | = 474/513
Therefore, the absolute value of the rational number -474/513 is 474/513.

In a raffle, 100 tickets are sold. George buys 10 tickets Julia by 5 tickets. There is one winning ticket. Find a probability that
a. George will win
b. jullia will win
The probability that George will win is 1/10 and the probability that Julia will win is 1/20.
What is probability?Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.The probability is calculated by dividing the total number of outcomes by the total number of potential events.So, calculate the probability as follows:
Probability formula: P(E) = Favourable events/Total eventsWe know,
The total number of tickets sold is 100.George has 10 tickets and Julia has 5.(A) George's probability of winning:
P(E) = Favourable events/Total eventsP(E) = 10/100P(E) = 1/10(B) Julia's probability of winning:
P(E) = Favourable events/Total eventsP(E) = 5/100P(E) = 1/20Therefore, the probability that George will win is 1/10 and the probability that Julia will win is 1/20.

From a group of eight people, two individuals are to be selected at random. How many selections are possible?
Answer:
28 different selections
Step-by-step explanation:
The number of ways in which k items can be drawn from a larger sample of n items is given by:
\(nC_k\;\) pronounced as "n choose k" relates to a class of problems known as combinatorics
\(nC_k\;\) is given by the formula
\(nC_k\; =\dfrac{n!}{k!(n-k)!}\)
where ! stands for the factorial of a number
n! = n x (n-1) x ...... x 3 x 2 x 1
Plugging values of n and k into the equation we get
\(8C_2\; =\dfrac{8!}{2!(8-2)!} = \dfrac{8!}{2!\;6!}\)
We can rewrite 8! as 8 x 7 x 6!
So
\(8C_2\; =\dfrac{8\cdot 7 \cdot 6!}{2!\; 6!} = \dfrac{8 \cdot 7}{2 \cdot 1} = \dfrac{56}{2} = 28\)

The scale factor used is:
1 centimeter equals half millimiter.
How to find the scale factor?The scale factor tells us how many units in the sculpture represent a real unit.
We know that:
Real length = 9mm
Length in the sculpture = 18cm
Then we have the relation between the lengths:
18cm = 9mm
Dividing both sides by 18 we will get:
1cm = 9mm/18
1cm = 0.5mm
So the scale is 1 centimeter equals half millimiter.

One angle's measurement is 11 times that of another. if the two angles supplementary one another. The measure of the angles area one is 165° and other angle is 15°.
Given that,
One angle's measurement is 11 times that of another. if the two angles supplementary one another.
We have to determine the angles' measurements.
The word "supplementary" refers to two angles coming together to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another
It has an acute angle on one side and an obtuse angle on the other.
The angles are both right angles.
So, It follows that A + B = 180°.
Angle A is 11 times angle B means
A=11B
We get,
11B+B=180
12B=180
B=180/12
B=15°
Then angle A is
A=11×15
A=165°

Janelle is planning to rent a car while on vacation. The equation C=0.32m + 15 models the relation between the cost in dollars, C, per day and the number of miles, m,she drives in one day. Find the cost on a day when Janelle drives the car 400 miles.
Answer:
cost when 400 miles is driven is $143.
Step-by-step explanation:
Model for cost calculation: C=0.32m + 15
We have to find cost when no. of miles driven is 400.
To find that cost we need to plug 400 in place of m.
C=0.32m + 15
=> c = 0.32*400 + 15
=> c = 128 + 15 = 143
Thus, cost when 400 miles is driven is $143.
Answer:
The C-intercept, 15, means that if Janelle drove 0 miles on a particular day it would cost her 15 dollars to rent the car for that day.

inches.
Answer:

Step-by-step explanation:Cube has all sides of equal dimensions and like that it has 6 faces.
So total surface area of cube is equal to the combined area of all the six faces.
Now each face has equal dimensions so same area
Therefore,
area of a single face =side²
Therefore, area of entire cube = 6 times the area of a single face
= 6 * side²
