Answer: It is $42.4
Step-by-step explanation: Multiply (0.20)(53), you get 10.6, now that's the price that is discounted, so subtract that from the total, to get $42.4. If you want to check your answer, do 42.4/53 and you would get 0.80, or 80%. That is what you should get since you have a 20% discount from 100% of a product.
Answer:
the sales price is $10.60
Step-by-step explanation:
to find 20% of 53, I multiplied 53 by 20 and 100 by a (i used the variable a to substitute for the answer we are going to get)
53 x 20 = 1060
100 x a = 100a
In order to get "a" we have to divide by 100 for each number.
1060 ÷ 100 = 10.6
100a ÷ 100 = a
in conclusion, a = 10.6, or $10.60 hope this helps :)

What is the solution to the equation 9x - 1
= 80.
X = -9
X = 1
x = 81
x=9
Answer:
x = 9
Step-by-step explanation
9x - 1 = 80
add 1 to both sides and you get
9x = 81
divide each side by 9 and you get
x = 9
The solution of equation 9x - 1 = 80 by combining like terms with the use of operations addition, division, etc is x = 9. Hence option 4 is true.
Used the concept of an equation that states that,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that the expression is,
9x - 1 = 80
Now simplify the expression by combining like terms with the use of operations addition, division, etc.
The expression is,
9x - 1 = 80
Add 1 on both sides,
9x - 1 + 1 = 80 + 1
9x = 81
Divide both sides by 9,
x = 81/9
x = 9
So, x = 9 is the solution of expression.
Thus option 4 is true.

The first term of an arithmetic sequence is 24 and the 19 term is-48. What is the
common difference?
Answer:
common difference d = - 4
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₁ = 24 and a₁₉ = - 48 , then
24 + 18d = - 48 ( subtract 24 from both sides )
18d = - 72 ( divide both sides by 18 )
d = - 4

Then, on Sunday she babysat her little brother for 2 hours.how many hours did she babysit on Saturday and Sunday .
Answer:
5 hours
Step-by-step explanation:
To change minutes to hours you will have to divide the total minutes by 60 (because 60 minutes is in one hour), in this situation it would look like this:
180/60 = 3
So, Alexa babysat for 3 hours on Saturday.
Now, just add the 3 hours from Saturday and 2 hours from Sunday and you get a total of 5 hours!

Chuck Stone is standing atop a high platform. He fires a rock up into the air with his slingshot. While it is in flight, the rock's distance in feet above the ground f(x) is a quadratic equation of time in seconds (x). This situation is modeled by the following function: f(x) = -5x^2 + 40x + 30.
a. How high above the ground is the platform?
30
b. How long does it take for the rock to hit the ground? Show all work to receive full credit!
is 30 correct for a? and please help me with b! Thank you!!!
Answer:
a) the platform is 110 feet above the ground.
b) It takes 8.69 sec for the rock to hit the ground
Step-by-step explanation:
This situation is modelled by the following function: [tex]f(x) = -5x^2 + 40x + 30\\[/tex]
We need to answer the following questions.
a) How high above the ground is the platform?
First we find x using the formula: [tex]x=-\frac{b}{2a}[/tex]
we have b = 40 and a = -5
Putting values and finding x
[tex]x=-\frac{b}{2a}\\x=-\frac{40}{2(-5)}\\x=-\frac{40}{-10}\\x=4[/tex]
Now putting x=4 in the function to find how high above the ground is the platform
[tex]f(x) = -5x^2 + 40x + 30\\Put\:x=4\\f(4)=-5(4)^2+40(4)+30\\f(4)=-5(16)+160+30\\f(4)=-80+160+30\\f(4)=110[/tex]
So, the platform is 110 feet above the ground.
b) How long does it take for the rock to hit the ground? Show all work to receive full credit!
We will factorise the given function [tex]f(x) = -5x^2 + 40x + 30[/tex] to find the time taken to hit the ground.
We can solve the equation using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a =-5, b=40, c=30
Putting values and finding x
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-40\pm\sqrt{(40)^2-4(-5)(30)}}{2(-5)}\\x=\frac{-40\pm\sqrt{1600+600}}{-10}\\x=\frac{-40\pm\sqrt{2200}}{-10}\\x=\frac{-40\pm46.9}{-10}\\x=\frac{-40+46.9}{-10},x=\frac{-40-46.9}{-10} \\x=-0.69,x=8.69[/tex]
So, we get values of x: x = -0.69 and x=8.69
As time cannot be negative, so we take x=8.69
So, It takes 8.69 sec for the rock to hit the ground

What is 3,348 rounded to the nearest hundred?
Answer:
3,300
Step-by-step explanation:
Answer:
3, 348 rounded to the nearest hundred is 3, 300.
Step-by-step explanation:
Let's have a look at the hundreds place. The number "3" is in the hundreds place, which has the value 300 since 3*100 = 300. What is the number next to the three in the hundreds place? Well, it is 4, which has the value of 40 since 4*10 = 40.
Remember, 4 or less, let it rest (this means keep the number and make the other numbers after it into zeroes).
5 or more, let it soar (this means to add one to the number and make the other numbers after it into zeroes).
HELPPPPPP SOLVE FOR X
Answer:
x = 6
Step-by-step explanation:
These are supplementary angles.
This means that the angles add up to 180 degrees.
The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.
6y = 90
y = 15
Now that we have found y we can solve for x.
Plug in the y to the 5x + 4y
5x + 4(15)
5x + 60
We can set this equal to 90 again
5x + 60 = 90
5x = 30
x = 6
Therefore x is equal to 6.
I hope this helps!!

Answer:
x= 6
Step-by-step explanation:
Straight line: is equaled to 180 degrees.
6y= 90 (90 divided by 6= 15), so y= 15
5x + 4y= 90 --> 5x + 4(15)= 90 --> 5x + 60= 90 --> 90 - 60= 30 --> 5x= 30 (30 divided by 5= 6), so x= 6
