Step-by-step explanation:
Mary spends 8*6=48 dollars
Pete spends 9*12=108
Mary got a better deal per cupcake
Answer:
They spent the same amount per cupcake ($1.33)
Step-by-step explanation:
To solve this, we need to find the unit rate of cost per cupcake. To do that, we divide 8 by 6 and divide 12 by 9. When we do that, we get 1.33 for both. That means they spent the same amount per cupcake ($1.33).

20% of all the children in a class are left handed.
4 children are left handed.
How many children are there in the class altogether?
Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have
[tex]\frac{20}{100} \times x = 4[/tex]
[tex]x = \frac{4 \times 100}{20}= 20[/tex]
There are 20 children in the class altogether
err i dont know U>U here you go peeps
Answer:
[tex] {x}^{2} + {y}^{2} + 4x - 2y = - 1 \\ ( {x}^{2}+2\times2\times x + {2}^{2} ) - 4 + ({y}^{2} - 2 \times 1 \times y + {1}^{2} ) - 1 = - 1 \\ {(x + 2)}^{2} - 4 + {(y - 1)}^{2} - 1 = - 1 \\ {(x + 2)}^{2} + {(y - 1)}^{2} = 4\\ {(x + 2)}^{2} + {(y - 1)}^{2} = {( 2) }^{2} [/tex]
Therefore, the centre of the circle is in ( -2, 1 )

Josh is 6 years older than 4 times Kim's age. the sum of their ages is less than 31.
what is the oldest Kim could be?
Answer:
4
Step-by-step explanation:
31 - 6 = 25
25/4 = 5
because its LESS than that, it has to be lower than 5, therefore its 4.
Kim should be 12 years old.
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Josh is 6 years older than 4 times Kim's age and the sum of their ages is less than 31.
From the information, let's consider Josh's age be J and that age Kim's be K
As given,
J = 6 + K ..............(i)
And,
J+K < 31
Substituting in eq(i)
6+K+K < 31
2K < 25
K < 25/2
K < 12.5
Since, Kim's age should be less than 12.5
Hence, Kim's age is 12 years.

Determine one number that summarizes the 5 numbers
First, one can use the mean to get the summary of the numbers.
The mean is calculated as:
[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]
[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]
[tex]Mean = \frac{60}{5}[/tex]
[tex]Mean = 12[/tex]
Another number that summarizes the numbers is the mode of the distribution.
[tex]Mode = Highest\ Occurring\ Value[/tex]
So, in this case:
[tex]Mode = 11[/tex]
Hence, you can either use 11 minutes or 12 minutes.

An asteroid is 10^{8} miles away from earth, and it is traveling at a speed of 10^{5} miles per day.
How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
