The number of friends that were called on Sunday are 27 friends.
On Friday, the number of friends Sharon called = 3 friends
On Saturday, the number of each of those 3 friends called 3 different friends.
Therefore the number of friends on Saturday = 3×3
= 9
The number of friends called on Sunday = 9 × 3
= 27
Therefore the number of friends called on Sunday= 27

If you multiplying by 1/4 makes a positive number smaller, then what does dividing by 1/4 do to the value of the number? Explain your reasoning
Division and multiplication are reciprocal operators.
Dividing the positive number by 1/4 will make the positive number bigger.
From the question, we understand that:
1/4 makes the positive number smaller, when it is multiplied to the positive number.
Because division and multiplication are reciprocals,
Dividing the positive number by 1/4 will make the positive number bigger.
Hence, what division does to the positive number is that: It makes it bigger

Which unit rates would be appropriate for describing the amount of rainfall over time?
Select each correct answer.
meters per second
milliliters per minute
centimeters per day
inches per hour
The unit rate appropriate for describing the amount of rainfall over time is centimeters per day. Therefore, option C is the correct answer.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Here,
Rainfall amount is expressed as the quotient of a unit of height and a unit of time.
The way to choose the most appropriate is the relation between both quantities.
For example, "meters per second" is a way too high unit for the height (which is usually inches or millimeters, instead of meters) and way too low for the time unit (which is usually per day, not seconds). This unit would have a really small number for any rain.
The most common unit is "centimeters per day"
Then, we should find a unit rate with a small unit for height and a large unit for time.
Therefore, option C is the correct answer.

Which equation is a point slope form equation for line AB ?
A. y+1=−2(x−6)
B. y+6=−2(x−1)
C. y+5=−2(x−2)
D. y+2=−2(x−5)
Answer: D . [tex]((y+2)=-2(x-5)[/tex]
Step-by-step explanation:
The equation of a line passing through two points (a,b) and (c,d) in point-slope form is given by :-
[tex](y-d)=\dfrac{d-b}{c-a}(x-c)[/tex]
From the given graph ,it can be seen that the line is passing through two points A(1,6) and B(5,-2).
Then the equation for the line AB in point-slope form would be :-
[tex](y-(-2))=\dfrac{-2-6}{5-1}(x-5)[/tex]
[tex]\Rightarrow\ (y+2)=\dfrac{-8}{4}(x-5)[/tex]
[tex]\Rightarrow\ (y+2)=-2(x-5)[/tex]
Hence, the equation is a point slope form equation for line AB :
[tex](y+2)=-2(x-5)[/tex]

15/16 is 1 sixteenth group of what size?
15/16 is 1 sixteenth group of size 1.0667.
15/16 represents a fraction where the numerator (15) is smaller than the denominator (16), indicating that it is less than a whole. When we express 15/16 as a mixed number, we get 15/16 = 0.9375, which means it is almost a whole.
In terms of groups, 15/16 can be thought of as 15 groups of a certain size out of 16. To find out the size of each group, we divide the total (16) by the number of groups (15), which gives us 16 ÷ 15 = 1.0667. Therefore, 15/16 is 1 sixteenth group of size 1.0667.
In other words, if we divide the whole into 16 equal parts, each part would be approximately 1.0667 units in size, and taking 15 of these parts would give us 15/16 of the whole.
This demonstrates that fractions can be interpreted as division problems and can be represented in various ways to understand the concept more deeply.

Answer: [tex]\dfrac{1}{90}[/tex]
Step-by-step explanation:
Given : The total number of companies = 720
The number of companies won = 8
Now, the probability of a company winning is given by ;-
[tex]\text{P(winning)}=\dfrac{\text{Number of company wins}}{\text{ Total companies}}\\\\\Rightarrow\ \text{P(winning)}=\dfrac{8}{720}\\\\\Rightarrow\ \text{P(winning)}=\dfrac{1}{90}[/tex]

Julie cashed a paycheck and repaid her brother $10 that she had borrowed from him. She then spent $30 on fuel for her car and half of the remaining money on a new tent for camping. She bought a pair of running shoes for $29.45 and had $17.75 left. How much did Julie receive when she cashed her paycheck?
Answer:
Julie received $134.4 when she cashed her paycheck .
Step-by-step explanation:
Let the amount of paycheck be x
She paid $10 to her brother
She then spent $30 on fuel for her car
So, She left with amount = x-40
Now She spent half of the remaining money on a new tent for camping
Spent on camping = [tex]\frac{1}{2}(x-40)[/tex]
Remaining = [tex](x-40)-\frac{1}{2}(x-40)[/tex]
She bought a pair of running shoes for $29.45
So, Remaining = [tex](x-40)-\frac{1}{2}(x-40)-29.45[/tex]
We are given that She had $17.75 left.
So, [tex](x-40)-\frac{1}{2}(x-40)-29.45=17.75[/tex]
[tex]x=134.4[/tex]
Hence Julie received $134.4 when she cashed her paycheck .
Keri uses the digits 7,5,4 and 8. Help Kerri write down all possible A. 4 digit odd numbers B. 4 digit even numbers. Use digit only once in each number.
To write down 4-digit odd and even numbers using the digits 7, 5, 4, and 8, there are 4 possible odd numbers and 2 possible even numbers.
Explanation:In order to write down all possible 4-digit odd and even numbers using the digits 7, 5, 4, and 8, we need to consider the following:
An odd number always ends with an odd digit, which in this case can only be 7 or 5. So, we have two options: 75 or 57.The remaining two digits can be arranged in any order. We have 2 options for the first digit (4 or 8) and 1 option for the second digit (the remaining digit).Therefore, for 4-digit odd numbers, we have a total of 2 * 2 * 1 = 4 possible numbers: 754, 584, 758, and 578.An even number always ends with an even digit, which in this case is 8. So, we need to choose an even digit for the thousands place. We have one option, which is 4. The remaining two digits can be arranged in any order.Therefore, for 4-digit even numbers, we have a total of 1 * 2 * 1 = 2 possible numbers: 854 and 584.can some one please help with this PLEASE

Factor 5x2 - 7x + 2.
The factored form of the given expression 5x² - 7x + 2 is equal to (5x - 2)(x - 1).
To factor the quadratic expression 5x² - 7x + 2,
find two binomials in the form (ax + b)(cx + d) whose product gives us the original expression.
The general form of a quadratic expression is ax² + bx + c, where:
a = 5
b = -7
c = 2
To factor the expression, look for two numbers whose product is ac (5× 2 = 10) and whose sum is b (-7).
The two numbers are -5 and -2 because:
-5 × -2 = 10
-5 + (-2) = -7
Now, rewrite the middle term (-7x) using these two numbers:
5x² - 5x - 2x + 2
Next, we group the terms and factor them by grouping:
(5x² - 5x) + (-2x + 2)
Factor out the greatest common factor from each group:
5x(x - 1) - 2(x - 1)
Now, factor out the common binomial factor (x - 1):
(5x - 2)(x - 1)
Therefore, the factored form of 5x² - 7x + 2 is (5x - 2)(x - 1).

Answer:
The expression [tex]18-3x[/tex] describe the number of tokens Nadeen has left.
Step-by-step explanation:
Consider the provided information
Nadeen is at an arcade. She started with 18 tokens. Each game costs 3 tokens.
The cost of each game is 3 tokens
Suppose x is the number of games played by Nadeen
Thus, the cost of x games is 3x tokens
it is given that Nadeen started with 18 tokens.
So, token left = [tex]18-3x[/tex]
Therefore, the expressions [tex]18-3x[/tex] can be used to describe the number of tokens Nadeen has left.
