athletic shoes: $79.99
discount: 40%
Answer:
48$ -specific (not rounded)
Step-by-step explanation:
There could be other solutions that can work. Such as counting the 79.99 to just 80. But for the very SPECIFIC value, you have to find 40% of 79.99 by multiplying it by .4 . 79.99*.4 = 31.99. After that, you would subtract 79.99 and 31.99 which would get you to 48.
Answer:
$47.99
Step-by-step explanation:
79.99*40/100
79.99*0.4
40% of $79.99 = $32.00 ( rounded )
79.99 - 32 = $47.99
For dinner, jerry had a double cheeseburger and one order of medium fries totalalling 1200 calories. Joe has two double cheeseburgers and one medium fry totalling 1260 calories. How many callories are in one cheeseburger and medium frys
Answer: See explanation
Step-by-step explanation:
Let the number of callories that are in one cheeseburger be = x
Let the number of calories that are in one medium frys be = y
Therefore, the question can be formed into an expression as:
Jerry = 1x + 1y = 1200
Joe = 2x + 1y = 1260
x + y = 1200 ....... i
2x + y = 1260 ....... ok
Subtract equation i from ii
x = 60
Therefore, number of callories that are in one cheeseburger is 60 calories
Since x + y = 1200
60 + y = 1200
y = 1200 - 60
y = 1140 calories
The number of calories that are in one medium frys is 1140 calories

What is a pendulum?
Answer:
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position
EXAMPLES:
the tick in a grandfather clock, a wrecking ball suspended by a chain or link
Step-by-step explanation:
hope this helps! please mark brainliest:)
A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity
Pendulum: A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity. The bob is typically attached to a string, rod, or wire that allows for free movement.
When a pendulum is set in motion, it swings back and forth in a regular and repetitive pattern.
The motion of a pendulum is governed by several factors, including the length of the pendulum, the mass of the bob, and the gravitational acceleration.
The swinging motion of a pendulum is influenced by two fundamental principles:
1. Period: The period of a pendulum is the time it takes for the pendulum to complete one full swing from one side to the other and back. The period depends on the length of the pendulum and is not affected by the mass of the bob. A longer pendulum will have a longer period, while a shorter pendulum will have a shorter period.
2. Oscillation: The pendulum oscillates due to the force of gravity acting on the bob. As the pendulum swings to one side, it gains potential energy, which is then converted into kinetic energy as it swings back. This energy transfer causes the pendulum to continue swinging back and forth.

The equation x+3y=2 can be rewritten in the equivalent form y=___x+____ which revels a slope equals to ___
-3,-2,-1,-2/3,-1/3,1/3,2/3,1,2,3
Hello!
[tex]\large\boxed{Slope = -\frac{1}{3}}[/tex]
x + 3y = 2
Rewritten into slope form: y = mx + b
Find the slope when rewritten:
Move x to the right hand side of the equation. (Subtract)
x - x + 3y = 2 - x
3y = 2 - x
Divide both sides by 3:
y = 2/3 - 1/3x
Rearrange:
y = -1/3x + 2/3.
The slope is equivalent to -1/3.

Isaac buys eggs and apples at the store. He pays a total of $24.26. He pays a total of $4.36 for the eggs. He buys 5 bags of apples that each cost the same amount.
Let x be the cost of each bag of apples. Then the equation is given as,
5x + 4.36 = 24.26
Simplify the equation, then we have
5x = 24.26 - 4.36
5x = 19.90
x = 19.90 / 5
x = $3.98

Andrea and Peter are riding their bicycles in the same direction on the same path. Andrea started 6 miles ahead of Peter and is traveling at a rate of 12 miles per hour. Peter is traveling at a rate of 14 miles per hour. After how many hours will Peter catch up to Andrea? Write and solve an equation to model the problem. Explain the meaning of the solution.
Answer:
3 hours
Step-by-step explanation:
Step one:
given
Andrea started 6 miles ahead of Peter and is traveling at a rate of 12 miles per hour.
let the number of hours be x
and the total distance traveled be y
y=6+12x------------1
the initial distance is 6 miles
the distance traveled after x hours = 12x
Peter is traveling at a rate of 14 miles per hour.
y=14x------------2
the initial distance is 0 miles
the distance traveled after x hours = 14x
Step two:
let us equate the two expressions above
6+12x=14x
14x-12x=6
2x=6
divide both sides by 2
x=6/2
x= 3 hours
it will take 3 hours for both of them to cover the same distance

Square number (2x+5y)(3x^2-4xy+2y^2)
Answer: 6x³+7x²y-16xy²+10y³
Step-by-step explanation:
( 2x + 5y )( 3x² - 4xy + 2y²)
⇒ (2x * 3x² ) = 6x³
⇒ (2x * - 4xy) = -8x²y
⇒ (2x * 2y² ) = 4xy²
⇒ (5y * 3x² ) = 15x²y
⇒ (5y * - 4xy) = -20xy²
⇒ (5y * 2y² ) = 10y³
( 2x + 5y )( 3x² - 4xy + 2y²) = 6x³-8x²y+4xy²+15x²y-20xy²+10y³
= 6x³+7x²y-16xy²+10y³
