1. 40/100 × 129.50 = 51.80
2. 129.50 - 51.80 = 77.70
3. 15/100 × 77.70 = 11.66
4. 77.70 + 11.66 = 66.04
The final cost of the roller blades is $ 89.66
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of purchase be = A
Now , the initial cost of roller blades = $ 129.50
The discount percentage of roller blades = 40 %
So , the equation will be
The cost of the roller blades after discount = 129.50 - ( 40/100 ) x 129.50
= 129.50 - 51.8
= $ 77.7
Now ,
The sales tax percentage of roller blades = 15 %
So , the equation will be
The cost of roller blades after sales tax = 77.7 + ( 15/100 ) x 77.7
= 77.7 + 11.655
= $ 89.655
Therefore , the final cost is A = $ 89.66
Hence , The final cost of the roller blades is $ 89.66

you flip a coin 10 times in a row. every single time it comes up heads. on the 11th flip, is it more likely to be heads, tails, or are heads and tails equally likely
Answer:
1/2
Step-by-step explanation:
It will be either heads of tails equally likely.
It’s still 1/2. Flipping a coin is an independent event. In other words, the outcome of the next flip is uninfluenced by what has happened previously. It’s as if it were the first time you ever flipped the coin. The probability is unaltered.

x = 55
Step-by-step explanation:
[tex](x + 40) \degree = (150 - x) \degree \\ (vertical \: \angle s) \\ \\ x + 40 = 150 - x \\ \\ x + x = 150 - 40 \\ \\ 2x = 110 \\ \\ x = \frac{110}{2} \\ \\ x = 55[/tex]
Answer:

Write an equation of a line with slope -3/2 and x-intercept (4,0)
Answer:
An equation of a line with slope -3/2 and x-intercept (4,0) will be:
[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven
Slope m = -3/2x-intercept (4, 0)now substitute m = -3/2 and the point (4, 0) in the slope-intercept form of line equation
[tex]y = mx+b[/tex]
[tex]0\:=\:-\frac{3}{2}\left(4\right)\:+\:b\:\:\:\:\:[/tex]
[tex]-6+b=0[/tex]
Add 6 to both sides
[tex]-6+b+6=0+6[/tex]
Simplify
[tex]b=6[/tex]
Thus, the y-intercept b = 6
now substitute m = -3/2 and b = 6 in the slope-intercept form of line equation
[tex]y = mx+b[/tex]
[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]
Therefore, an equation of a line with slope -3/2 and x-intercept (4,0) will be:
[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]
and no boxes were removed, all the boxes in the warehouse were arranged in stacks of 14 boxes each, with no boxes left over. How many boxes were in the warehouse before the 60 additional boxes arrived
Answer:
360 boxes
Step-by-step explanation:
The number of boxes in the warehouse before 60 boxes were added is;
n = 12k .... equation 1
where k is the constant of the number of stacks and n is the number of boxes.
The number of boxes after the 60 boxes were added is;
n + 60 = 14k ... equation 2
substitute the value of n in equation 2 for equation 1:
12k + 60 = 14k
60 = 14k - 12k
60 = 2k
k = 60 / 2 = 30
The number of boxes in the warehouse before 60 boxes was added is;
n = 12 * 30 = 360

There are 6 people in Jacob’s family. Jacob’s sister is 5 years younger than he is. He has twin brothers who are 3 years older than he is. His mom is 3 times Jacob’s age, and his dad is 4 years older than his mom. The total of all the ages of all his family members is 165 years. How old is Jacob? Define a variable, write an equation, and solve the problem.
Answer:
Jacob is [tex]16[/tex] years old.
Step-by-step explanation:
Let the age of Jacob be [tex]x[/tex] years.
Jacob’s sister is [tex]5[/tex] years younger than he is.
So, the age of Jacob's sister be [tex]x-5[/tex] years.
Jacob's twin brothers are [tex]3[/tex] years older than he is.
So, the age of each of the twin brother be [tex]x+3[/tex] years.
Jacob's mom is [tex]3[/tex] times his age.
So, the age of Jacob's mom be [tex]3x[/tex] years.
Jacob's dad is [tex]4[/tex] years older than his mom.
So, the age of Jacob's dad be [tex]3x+4[/tex] years.
Now, the total of all the ages of all his family members is [tex]165[/tex] years.
So, [tex]x+x-5+x+3+x+3+3x+3x+4=165[/tex]
[tex]\Rightarrow 10x+5=165[/tex]
[tex]\Rightarrow 10x=165-5[/tex]
[tex]\Rightarrow 10x=160[/tex]
[tex]\Rightarrow x=\frac{160}{10}[/tex]
[tex]\Rightarrow x=16[/tex]
Hence, Jacob is [tex]16[/tex] years old.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is to determine the product of two or more numbers. If an event can occur in m different ways and if following it, that a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We don not write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together.
We are given the number as 9 x 3
WE can see that the number is multiple of 3
Therefore by using simplification we get;9 x 3 = 27
Hence, the answer is 27.

A. 28.26cm
B. 37.68cm
C. 18.84cm
D. 56.52cm
Answer:
Option D
Step-by-step explanation:
circumference: 2pi x r
r = 9 (6 + 12)/ 2
2 x pi x 9
= 18 pi cm^2 = 56.55 cm^2
Answer:
D. 56.52 cm
Step-by-step explanation:
Circumference = 2*pi*r
Based on the picture, we can see the largest circle has a diameter of 18 cm. (12 + 6)
The radius of the largest circle is half of it's diameter: 18/2 = 9 cm
Now put in the numbers for the circumference equation:
Circumference = 2 * pi * 9 (9 is the radius)
Circumference = 56.5 cm
