The selling price of an item is $650. It is marked down by 20%, but this sale price is still marked up from the cost of $400. Find the markup from cost to sale price.
Answer: The markup from cost to sale price = $120.
Step-by-step explanation:
Given: Selling price per item = $650
Marked down price = 20% of (Selling price)
= 0.20 x $650
= $ 130
New selling price = Old selling price - Marked down price
= $(650-130) = $520
Since new selling price is still greater than the cost of $400.
Mark up from cost to selling price = New selling price - Cost
= $(520-400)
=$120
Hence, the markup from cost to sale price = $120.

Gabriella is three years younger than her sister, Amy. If
Gabriella is 5 years old, how old is Amy? Write an equation
to solve
Answer:
5+3 is Amy, so Amy is 8
Step-by-step explanation:
So, lets say amy is a
and gabriella is g
WE know that g=5, because gabriella is 5 years old
And, Gabriells is younger than Amy, so we need to add to get Amy's age
So, 5 ( Gabriella's age ) + 3=Amy
So, 5+3= Amy
So Amy is 8
Answer:
Amy is 8 years old.
Step-by-step explanation:
5 + 3 = 8
If Gabriella is three years younger then Amy then all you have to do is add 5 (Gabriella's age) plus 3 (how much older Amy is than Gabriella) and that is 8.

Three times a number (n) is 36 less than five times the number (n). What is the number?
Answer:
18
Step-by-step explanation:
To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.
Now, break it by parts - "three times a number" would be [tex]3n[/tex]. The "is" means that it equals something, giving us [tex]3n =[/tex]. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: [tex]5n -36[/tex]. So, put it all together and it is [tex]3n = 5n-36[/tex].
Next, solve the equation for n. The answer will be the number.
[tex]3n = 5n-36\\0 = 2n - 36\\36 = 2n \\n = 18[/tex]
Thus, the number is 18.

You flip a coin 100 times in the air and find that it lands on heads 65 times. Determine the theoretical and experimental probability of landing on heads. In your final answer, include all of your calculations.
Answer:
The experimental probability --> [tex]\frac{13}{20}[/tex]
The theoretical probability --> [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Key skills needed: Experimental vs theoretical probability, Fractions
1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)
- Theoretical probability is based on simple reasoning
- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)
2) Now with this, let's start solving:
Experimental probability ---> [tex]\frac{heads}{total}[/tex] --> You flipped the coin a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator. So our experimental probability is --> [tex]\frac{65}{100}[/tex] --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> [tex]\frac{13}{20}[/tex] Now onto theoretical probability --> [tex]\frac{heads}{total}[/tex] --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means --> Our theoretical probability is [tex]\frac{1}{2}[/tex]Hope you understood and have a nice day!! :D
Answer:
Experimental Probability: 65/100 We tested the probability 100 times, 65 of those times being heads. So %65 is our experimental probability (in percentage form) of flipping a coin and landing on heads. Simplified, 13/20 is our fraction.
Theoretical Probability: 50/100 or 1/2. There are two sides to a coin, and one is heads, so the theoretical probability is 1/2. In percentage form, the probability would be %50, or 50/100.

We have the correct feet number (5) but the incorrect inches number (should be 3 inches and not 1/4 inches)
Step-by-step explanation:
Here, we want to make a conversion from feet to inches and feet
Mathematically, we know that;
1 feet = 12 inches
So, for 63 inches, we can have a clear ;
63/12 = 5 feet + 3 inches
Hence, the correct conversion of 63 feet should be;
5 feet and 3 inches

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
Answer:
∠ A = 65°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°
∠ D + ∠ B = 180°, that is
x + 148 = 180 ( subtract 148 from both sides )
x = 32
Thus
∠ A = 2x + 1 = 2(32) + 1 = 64 + 1 = 65°
The measure of angle inscribed in the circle m∠A = 65°
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the quadrilateral inscribed inside the circle be ABCD
Now , the measure of m∠B = 148°
The measure of m∠D = x°
The measure of m∠A = ( 2x + 1 )°
For a quadrilateral inscribed inside a circle , the opposite angles are supplementary
And , the measure of m∠B + measure of m∠D = 180°
On simplifying , we get
x + 148° = 180°
Subtracting 148° on both sides , we get
x = 32°
Now , the measure of m∠A = ( 2 ( 32 ) + 1 ) °
The measure of m∠A = 65°
Hence , the measure of angle A of the quadrilateral of circle is 65°
