Answer:
20%
Step-by-step explanation:
Given parameters:
Marked price = Rs. 100
Selling price = Rs. 80
Unknown:
Discount rate = ?
Solution:
The price on the label of an article is the marked price;
Discount amount = Marked price - selling price
= Rs. 100 - Rs. 80
= Rs. 20
Discount rate = [tex]\frac{Discount }{Marked price } x 100[/tex]
Discount rate = [tex]\frac{20}{100}[/tex] x 100 = 20%

The University of Washington Huskies tried throwing one of the longest Hail Mary's in history
- about 73 yards. For this pass, the ball's height over time was modeled by the function
h(t) = –16t2 + 64t + 6, where h(t) was the height in feet and t was the time in seconds.
Let's break down whether the Huskies ever had a chance.
1.
73 yards isn't just a long way to throw, it's a long way to run. To give his team the
best chance of running all the way down the field and catching the ball before it hits
the ground, the quarterback (passer) needs to keep the football in the air for a long
time. How long was the ball in the air?
9514 1404 393
Answer:
4.09 seconds
Step-by-step explanation:
The ball is in the air until h(t) = 0. Solving that equation for t, we have ...
0 = -16t^2 +64t +6
t^2 -4t = 3/8 . . . . . . rearrange, divide by 16
t^2 -4t +4 = 4 3/8 . . . add 4 to complete the square
(t -2)^2 = 4.375 . . . . write as a square
t = 2 +√4.375 . . . . . positive square root, add 2
t ≈ 4.09165
The ball was in the air about 4.09 seconds.
For Anthony’s birthday, his mother is making cupcakes for his 12 friends at his daycare. The recipe calls for 3 1/3 cups of flour. This recipe makes 2 1/2 dozen cupcakes. Anthony’s mother has only 1 cup of flour. Is there enough flour for each of his friends to get a cupcake
Answer:
No, there is no enough flour for each of his friends to get a cupcake
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes
∵ Each dozen contain 12 cupcakes
∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex] × 12
∴ The number of cupcakes can the recipe make = 30 cupcakes
∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour
→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes
∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes
∵ Anthony’s mother has only 1 cup of flour
→ By using the ratio method
→ flour : cupcake
→ 3[tex]\frac{1}{3}[/tex] : 30
→ 1 : x
→ By using cross multiplication
∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30
∴ 3[tex]\frac{1}{3}[/tex] x = 30
→ Divide both sides by 3[tex]\frac{1}{3}[/tex]
∴ x = 9
∵ x represents the number of cupcakes
∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour
∵ Anthony has 12 friends at his daycare
∵ The number of the cupcakes = 9
∴ The number of cupcakes is not enough for each of his friends to
get a cupcake

Answer:
3 mph
Step-by-step explanation:
To make 1/9 hour to 1 hour, you need to x9.
You can use this way:
Let the speed be x
(1/3)/(1/9)=x/1

On a chapter test, Stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. The directions on the test are not very specific, however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer.
4x3 = 756
What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution.
Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation.
After solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in Part 1) to Stephanie regarding the format of her answer? Use complete sentences to explain your reasoning.
Answer:
Since, we are asked to present an exact solution, we are not able to give approximations.
The term exact means that you need to give the answer like this:
If we were asked to give an approximate result it would be like this x = 5,738.

1. Make a proportion.
Set the numbers equal to each other.
I chose the numbers 9, 12, 15, and of course x.
Make the fractions in a way that the x is in the numerator if you want to make your life easier.
15/9 = x/12
2. Simplify
Cross multiply the numbers.
This will give you the equation of
9*x and 15*12
3. Make an equation
Simplify the numbers by mulitplying them
9x = 180
4. Divide both sides by 9
9x = 180
/9 /9
x = 20Hope this helped,

A scientist had 1.25 ounces of a chemical. He bought 2.5 ounces more of the chemical and then used 0.75 ounce in an experiment. How much chemical does the scientist have remaining?
Answer:
3 ouncesStep-by-step explanation:
Step one:
given data
the initial amount of chemical = 1.25 ounces
Extra amount of chemical =2.5 ounces
Total amount of chemical =1.25+2.5=3.75 ounces
Step two:
we are told that the scientist used 0.75 ounces of chemical
Hence the remaining chemical is
remaining= 3.75-0.75
remaining= 3 ounces
The remainder is 3 ounces

A linear function has the same y-intercept as x + 4y = 8 and its graph contains the point (5,3). Find the slope of the linear function. Write the slope in fraction form.
Answer:
x - 5y = - 10
Step-by-step explanation:
y = mx + b (b is y-intercept)
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~
x + 4y = 8 ⇔ y = [tex]-\frac{1}{4}[/tex] x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are (0, 2)
(5, 3)
m = [tex]\frac{3-2}{5-0}[/tex] = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x + 2 (slope-intercept form)
x - 5y = - 10 (standard form)

Answer:
2(x-3x) + 3
value of X and M is x and -3x respectively
Step-by-step explanation:
you can factor out the 2 from the 2x -6x and gets the 2(x-3x) while n is the constant that remains the value of 3
I hope this helps
Answer:
m = - 3, n = - 6
Step-by-step explanation:
Expand and compare coefficients of like terms, that is
(x + m)² + n
= x² + 2mx + m² + n
Compare to x² - 6x + 3
comparing coefficients of x- term
2m = - 6 ( divide both sides by 2 )
m = - 3
Comparing constant terms
m² + n = 3 , that is
(- 3)² + n = 3
9 + n = 3 ( subtract 9 from both sides )
n = - 6
