Jonny is buying a new pair of shoes. If the shoes are normally $25.00 and are on sale for 20% off, how much will he pay for the shoes before tax?
Answer:
$20
Step-by-step explanation:
First, we need to find 20% of $25. You can do this by multiplying $25 by 0.2
After multiplying , you get $5. So 20% of 25 is 5.
Now, we subtract because the shoes are 20% off
25 - 5 = $20
I hope this helped, please mark Brainliest, thank you!
Answer:
If Jonny is buying a new pair of shoes for that were $25.00 before the shoes went on sale the shoes are now 12.50 ct

Which number line can be used to find the distance between (-1,2) and (-5,2)
Answer:
The number line is y = 2.
Step-by-step explanation:
We are given the points (-1,2) , (-5,2) and we have to find the number line that can be used find the distance between them.
The y coordinate of the two points is
same (equal to 2) , so the number line that can be used to find the distance between them is y = 2.
Distance between the points = |-5+1| = 4

A goat is tethered to a rope that is 3.65 meters long. What is the maximum area of grass that the goat can graze on?
Answer:
3.65 meters
Step-by-step explanation:
If the rope is 3.65 meters long, then the goat can only go as far as the rope is long. That's unless the goat eats the rope.
The maximum area that a goat can graze on will be the area of a circle where the center of the circle will be one end of the rope as shown in the attached diagram.
What is the area of a circle?The area of a circle with radius r is πr².
Radius of the circle= length of the rope = 3.65m
So, area of the circle = [tex]\pi r^{2}[/tex]
Area of the circle = [tex]\pi 3.65^{2}[/tex]
Area of the circle = 41.85m².
Therefore, the maximum area of grass that the goat can graze on is 41.85 m²

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 minutes. Find the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes.
Answer: 0.75
Step-by-step explanation:
Given : Interval for uniform distribution : [0 minute, 5 minutes]
The probability density function will be :-
f(x) = 1/5-0 = 1/5 = 0.2, 0<x<5
The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-
Hence, the probability that a randomly selected passenger has a waiting time greater than 1.25 minutes = 0.75

One number is selected from the set {1, 2, 3, 4, 5, 6, 7, 8, 9}. Find the probability the selected number is less than 7, given that it is less than 8.
Give your answer as a decimal rounded to 4 decimal places.
====================================================
Explanation:
We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.
Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.
The probability we're after is A/B = 6/7 = 0.8571
Answer:
I just got this question in my book, and i already solved it. so just saying that i now the answer, it is 0.8571

what are the property for each equation
Answer:
associative, distributive, commutative
Step-by-step explanation:
Commutative is something just flipped around so the 3rd equation would be commutative. Associative is something with the same numbers but asked in a different way so 1st would be associative. Distributive is breaking the equation down and apart to make it easier to complete so the 2nd would be distributive.

f (x) = 5x - 1, find f (4) - show work
Answer:
f(4) = 19
Step-by-step explanation:
Plug in 4 for x in the given equation:
f(x) = 5x - 1
f(4) = 5(4) - 1
Simplify. Remember to follow the order of operations, PEMDAS. First multiply, then subtract:
f(4) = (5 * 4) - 1
f(4) = 20 - 1
f(4) = 19
f(4) = 19 is your answer.

A pound has 60 German Shepherds and 40 Great Danes of both sexes. If they breed with each other randomly, what is the probability that the puppies are: (i) pure breed German Shepherds, (ii) pure breed Great Danes, (iii) German Shepherd-Great Danes
Answer:
(i) pure breed German Shepherds,= 0.6
(ii) pure breed Great Danes,= 0.4
(iii) German Shepherd-Great Danes= 0.24
Step-by-step explanation:
The probability of success for the German shepherd is 60/100 0r 6/10 0r 0.6
The probability of failure for the German shepherd is 40/100 0r 4/10 0r 0.4
The probability of success for the Great Danes is 40/100 0r 4/10 0r 0.4
The probability of failure for the Great Danes is 60/100 0r 6/10 0r 0.6
The probability that it is a pure German shepherd is 60/100 0r 6/10 0r 0.6
The probability that it is a pure the Great Danes is 40/100 0r 4/10 0r 0.4
The probability that the puppies are: German Shepherd-Great Danes is given by since the events are independent
P (GS ∩ GD) = 0.6* 0.4= 0.24
Find the directional derivative of the function f(x,y)=2cos(y)exf(x,y)=2cos(y)ex at the point (0,π6)(0,π6) in the direction of the vector v=⟨−8,6⟩v=⟨−8,6⟩.
Answer:
[tex]D_u f(0,\pi/6)=\frac{4\sqrt{3}-3}{5}[/tex]
Step-by-step explanation:
We are given that
[tex]f(x,y)=2cos(y)e^{x}[/tex]
Point=([tex]0,\pi/6[/tex])
Vector v=<-8,6>
We have to find the directional derivative of the function.
[tex]f_x(x,y)=2cos(y)e^{x}[/tex]
[tex]f_x(0,\pi/6)=\sqrt{3}[/tex]
[tex]f_y(x,y)=-2sin(y)e^{x}[/tex]
[tex]f_y(0,\pi/6)=-1[/tex]
[tex]|v|=\sqrt{(-8)^2+6^2}=\sqrt{100}=10[/tex]
[tex]\hat{u}=\frac{v}{|v|}=\frac{-8i+6j}{10}=\frac{1}{10}(-8i+6j)[/tex]
[tex]\nabla f(0,\pi/6)=<f_x(0,\pi/6),f_y(0,\pi/6)>=<\sqrt{3},-1>[/tex]
Now, the directional derivative in the direction of v at point (0,[tex]\pi/6[/tex]) is given by
[tex]D_u f(0,\pi/6)=\nabla f(0,\pi/6)\cdot \hat{u}[/tex]
By using the formula
[tex]D_u f(x,y)=\nabla f(x,y)\cdot \hat{u}[/tex]
[tex]D_u f(0,\pi/6)=<\sqrt{3},-1>\cdot <-\frac{8}{10},\frac{6}{10}>[/tex]
[tex]D_u f(0,\pi/6)=-\frac{4\sqrt{3}}{5}-\frac{3}{5}=-\frac{1}{5}(4\sqrt{3}+3)[/tex]
