Answer:
no they are not equivalent
Step-by-step explanation:
0.4/15 = 0.026
so for every minute they travel 0.026km
0.6/20 = 0.03
so for every minute they travel 0.03km
so they are not the same/equivalent

A computer was on sale for 270 if the original price was cut by 40% what was the original price
explain.
Answer: 108
Step-by-step explanation: The 40% percent taken away from $270 would be $108, because I round it to 50% percent off and that would $135 but since it's 40% off not 50% so I took away 10% from $135, and that's how I found my answer .
The five marathon runners weigh an average weight of 92 pounds, Nicole weighs 89 pounds, Jon weighs 95 pounds, Jenny and Kim weigh 90 pounds each, How much does Jordin weigh?
Answer:
Jordin weighs 96 pounds
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]
Jordin weighs 96 pounds

HELP PLS 19 and 40 degrees
Answer:
x ≈ 14.6
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{19}[/tex] ( multiply both sides by 19 )
19 × cos40° = x , then
x ≈ 14.6 ( to the nearest tenth )

Ryan collected data from a random sample of 700 students in his university asking whether or not they exercise more than 30 minutes per day. Based on the results, he reports that 36% of the students in the nation exercise more than 30 minutes per day. Why is this statistic misleading?
He only asked students in his university and he stated that it represented the whole nation (his university does not represent the whole country.)
To save costs dylan decides to decrese the size of the house she is building . Orginally the plans for the house show the dimensions of the house pad to be 20 ft by 30 ft . She reduces each dimension by 10 percent
Answer:
[tex]Length = 18[/tex]
[tex]Width = 27[/tex]
Step-by-step explanation:
Given
Dimension = 20 by 30
Reduction = 10%
Required
Determine the new dimensions
Because it is a reduction, the new dimension is calculated using:
[tex]New = Old (1 - Reduction)[/tex]
The new length is calculated as:
[tex]Length = 20(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Length = 20(1 - 0.10)[/tex]
[tex]Length = 20 * 0.90[/tex]
[tex]Length = 18[/tex]
The new width is calculated as:
[tex]Width = 30(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Width = 30(1 - 0.10)[/tex]
[tex]Width = 30*0.90[/tex]
[tex]Width = 27[/tex]
A backpack that regularly sells for $26 is on sale for 25% off the regular price. What is the sale price of the backpack
Answer:
Sale price of backpack is $19.5
Step-by-step explanation:
Original price of backpack = $26
Discount = 25%
We need to find sale price.
First we will find amount that will be discounted, and then subtract from original price.
So, Finding discount price
[tex]25\%of 26\\=\frac{25}{100}\times 26\\=6.5[/tex]
So, there will be discount of $6.5
Now, the sale price will be:
Sale price = Original Price - Discount
Sale Price = 26 - 6.5
Sale Price = 19.5
So, Sale price of backpack is $19.5
A boat is pulled into a dock by a rope with one end attached to the front of the boat and the other end passing through a ring attached to the dock at a point 5 feet higher than the front of the boat. The rope is being pulled through the ring at the rate of 0.6 ft/sec. How fast is the boat approaching the dock when 13 feet of rope are out
Answer:
The boat is approaching the dock at 0.65 ft/sec when 13 feet of rope are out.
Step-by-step explanation:
Let x be the length of rope and y be the distance between boat and dock.
Height of point where a ring attached =z=5 feet
[tex]\frac{dx}{dt}=-0.6ft/sec[/tex]
x=13 feet
Using Pythagoras theorem
[tex]H^2=P^2+B^2[/tex]
[tex]x^2=z^2+y^2[/tex]
[tex]x^2=5^2+y^2=25+y^2[/tex]
[tex](13)^2=25+y^2[/tex]
[tex]169-25=y^2[/tex]
[tex]144=y^2[/tex]
[tex]y=12 feet[/tex]
Differentiate w.r.t t
[tex]2x\frac{dx}{dt}=2y\frac{dy}{dt}[/tex]
[tex]x\frac{dx}{dt}=y\frac{dy}{dt}[/tex]
[tex]13(-0.6)=12\frac{dy}{dt}[/tex]
[tex]\frac{7.8}{12}=\frac{dy}{dt}[/tex]
[tex]\frac{dy}{dt}=-0.65feet/sec[/tex]
Hence,the boat is approaching the dock at 0.65 ft/sec when 13 feet of rope are out.
