Hana first decides to host a tea party. She has 60 tea sandwiches and 48 scones to serve. What is the greatest amount of people she can host, such that there will be no leftovers AND each person will receive the same number of sandwiches and scones, respectively?
Answer:
12
Step-by-step explanation:
She can host the greatest amount of people will be 12, such that there are no leftovers and each person will receive the same number of sandwiches and scones, respectively.
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.
Given that She has 60 tea sandwiches and 48 scones to serve
We have to determine the Greatest Common Factor (GCF) between 60 and 48
We need to write 60 and 48 as the product of their prime factors,
⇒ 2 × 2 × 3 × 5.
⇒ 3 ×2 × 2 × 2 × 2.
Here the Greatest Common Factor (GCF) is 12.
Thus, she can host the greatest amount of people will be 12, such that there are no leftovers and each person will receive the same number of sandwiches and scones, respectively.

Three out of 8 monkeys in the zoo eat less than 12 pounds of food. What is the decimal equivalent for the number of monkeys eating less than 12 pounds of food?
Answer: The decimal equivalent for the number of monkeys eating less than 12 pounds of food = 0.375
Step-by-step explanation:
Given: Three out of 8 monkeys in the zoo eat less than 12 pounds of food.
i.e. The fraction of monkeys eat less than 12 pounds of food =[tex]\dfrac38[/tex]
Divide 3 by 8, we get [tex]\dfrac38=0.375[/tex]
Hence, the decimal equivalent for the number of monkeys eating less than 12 pounds of food = 0.375

Describe the pair of angles shown in the figure.
Answer:
D
Step-by-step explanation:
As, complementary angles are those which add up to 90°,but those add up to 100°.So not option A
And it not supplementry angles because tge angles that add a 180°,so not option B
And not vertical, because if it was vertical then both of the angles would be equal so not option C
It is D because they both are adjacent to each other, therefore it is option D
The pair of angles shown in the figure will be Adjacent angles. Then the correct option is D.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Adjacent angle - When corresponding sides have a similar vertex and edge, they are referred to as Adjacent angles.
Then the pair of angles shown in the figure will be Adjacent angles.
Then the correct option is D.

Last month the local YMCA bought 2pounds of French fries for $4.56 for summer camp . The next month they purchased 12 pounds of French fries for $22.80 . What is the difference in the unit cost per pounds that the YMCA during summer camp?
Answer:
D = $0.38 per pounds
Step-by-step explanation:
It is given that,
Last month the local YMCA bought 2pounds of French fries for $4.56 for summer camp.
The next month they purchased 12 pounds of French fries for $22.80.
Unit cost per pound for last month is :
[tex]C=\dfrac{4.56}{2}=\$2.28\ \text{per pounds}[/tex]
Unit cost per pound for the next month is :
[tex]c=\dfrac{22.8}{12}=\$1.9\ \text{per pounds}[/tex]
Taking difference,
D = C - c
D = $2.28-$1.9
D = $0.38 per pounds
So, the difference that the YMCA during summer camp is $0.38 per pounds.

Daniel owes his sister $33. His sister said that she would give him a third off the debt. Write an expression that you could use to solve to find how much Daniel would owe his sister.
Answer:
P=33-11
Step-by-step explanation:
given that Daniel owes her $33
a third of $33
is 1/3*33
=$11
now let the amount Daniel will owe her after giving her a third of the debt be P
therefore the expression to find how much Daniel owes her will be
P=33-1/3*33
simplifying the expression we have
P=33-11
P=$22
Daniel will owe her $22

In the first 42 super bowls, 0.16 of the MVP's (most valuable players) were running backs. a. What percent of th MVP's were running backs? Write the percent as a mixed number.
Answer:
Percent of MVPs that were running back is 16.6%
The percent as a mixed number is 16 6/10% or 16 3/5%
5/6 of the MVPs were not running backs
Step-by-step explanation:
Here is the complete question:
In the first 42 Super Bowls, 0.16(repeating sign over 6) of the MVPs (most valuable players) were running backs. a. What percent of the MVPs were running backs? Write the percent as a mixed number. b. What fraction, in simplest form, of the MVPs were not running backs?
Step-by-step explanation:
From the question, 0.16(repeating sign over 6) of the MVPs were running backs. Since there is repeating sign over 6, then, we can say 0.166 of the MVPs were running backs.
a. To determine what percent of the MVPs were running running back, we will multiply 0.166 by 100%.
Hence, Percent of MVPs that were running back = 0.166 × 100% = 16.6%
To write the percent as a mixed number,
16.6 = 16 + 0.6 = 16 + 6/10 = 16 6/10 = 16 3/5
∴ 16.6% = 16 3/5%
Hence, the percent as a mixed number is 16 6/10% or 16 3/5%
b. To determine what fraction of the MVPs were not running backs, that will be
1 - 0.16(repeating sign over 6) = 0.83 (repeating sign over 3)
0.83(repeating sign over 3) as a fraction is 5/6
Hence, 5/6 of the MVPs were not running backs

Meg receives 10% commission on her first $5000 in sales. She receives 20% commission on any sales beyond the first $5000. Bonus: Do the amount of sales and Meg's commission form a proportional relationship? Why or why not?
Answer: There is no proportional relationship in commission and sales.
Step-by-step explanation:
to show a proportional relationship between two variables x and y , we write them as:
y= mx, where m = proportionality constant.
Let y = commission, x= sales , m= commission percent
Till x= $5000 , commission percent = 10%
Beyond x= $5000 , commission percent = 20%
i.e. m is not constant, but as x increases y also increases.
Hence, there is no proportional relationship in commission and sales.
Graph the line with the equation y=1/4x-4
Answer:
Step-by-step explanation:
The required graph of the line y = 1/4x - 4 is attached below that represents a straight line that slants upward from left to right,
To graph the line with the equation y = 1/4x - 4, we can use the slope-intercept form of a linear equation.
In the given equation, y = 1/4x - 4, we can identify the slope and y-intercept:
Slope (m) = 1/4
Y-intercept (b) = -4
The graph of the line y = 1/4x - 4 will be a straight line that slants upward from left to right, with a slope of 1/4 and crossing the y-axis at -4.

rebecca uses 3/4 gallon of paint to cover 1 wall. she has three gallons of paint. how many walls can she paint?
Answer:
4 walls
Step-by-step explanation:
First we could re-write 3 gallons with a denominator of 4 which would be 12/4 gallons. Next, we could divide like so:
12 divided by 3 = 4
Our answer is 4 walls
Hope this Helps!!! :)
She can paint 4 walls in 3 gallons of paint.
What is multiplication?Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.
Example - 2 × 3 means 2 is added three times or 3 is added 2 times.
Given, the Rebecca uses 3/4 gallon of paint to cover 1 wall.
And she has three gallons of paint.
Now to paint the wall;
number of wall that she can paint = number of gallon she has÷3/4
Number of wall that she can paint = 3 ÷ 3/4
Simplifying the above term to multiplication,
Number of wall that she can paint = 3 x 4/3
Number of wall that she can paint = 4
Therefore, she can paint 4 walls in 3 gallons of paint.
