To find out if a number is prime, it can only have two factors, 1 and itself.
The tax is 8.5%.
To find the tax on an item, multiply 8.5% by the price of the item.
t-shirt:
8.5% of $12.99 = 8.5% * $12.99 = 0.085 * $12.99 = $1.10
The tax on the t-shirt is $1.10
pair of jeans:
8.5% of $39.99 = 8.5% * $39.99 = 0.085 * $39.99 = $3.40
The tax on the jeans is $3.40
The difference in the amount of tax is
$3.40 - $1.10 = $2.30
Answer: $2.30
Deacon Middle School
5x = number of boys
4x = number of girls
where x is some unknown number for now
(number of boys)+(number of girls) = 270 students total
5x+4x = 270
9x = 270
x = 270/9
x = 30
Since x = 30, this means
number of girls = 4x
number of girls = 4*30
number of girls = 120
There are 120 girls at Deacon Middle School
-----------------------------------------
Similarly, for Meadow Middle school
number of boys = 4y
number of girls = 5y
for some number y
(number of boys) + (number of girls) = 180 students total
4y+5y = 180
9y = 180
y = 180/9
y = 20
making,
number of girls = 5*y
number of girls = 5*20
number of girls = 100
so there are 100 girls at Meadow Middle School
-----------------------------------------
In summary so far, there are...
120 girls at Deacon Middle School
100 girls at Meadow Middle School
In total 120+100 = 220 girls from both schools
This is out of 270+180 = 450 students total
Divide the two values (220 and 450) to get
220/450 = 22/45
The final answer is 22/45
It cannot be reduced further as there are no common factors (other than 1) between 22 and 45
Answer:
The first rule we will look at is the product rule for simplifying square roots, which allows us to separate the square root of a product of two numbers into the product of two separate rational expressions.
