Answer:
2X = Y
Step-by-step explanation:
To determine the equation that will allow to establish the amount of souvenirs bought by Aubrey (Y), taking into account that for each day of vacation (X) buys 2 souvenirs, the following must be taken into account:
The number of days (X) must be multiplied by 2. Thus, if you buy 2 souvenirs per day and your vacation lasts 4 days, you will have bought 8 souvenirs (4 x 2). Thus, the value of Y is equal to 2X, that is:
2X = Y

Answer:
$27.14
Step-by-step explanation:
Price of 1 DVD: $9.10
Price of 4 DVDs: 4 * $9.10 = $36.40
Discount: 25%
Now we find 25% of $36.40.
25% of $36.40 =
= 0.25 * $36.40
= $9.10
The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.
$36.40 - $9.10 = $27.30
Now we need to apply the 6.75% tax to $27.30.
6.75% of $27.30 =
= 0.0675 * $27.30
= $1.84
The sales tax is $1.84.
Now we add the sales tax amount to the total discounted price.
$27.30 + $1.84 = $29.14
Answer: $27.14

Devi rides the bus to her grandmother's house every day. She tracked how many minutes the bus rides took for one week: 24 32 25 24 30 30 24 calculate the mean, median, range, and mid range of the bus ride times for a week
Answer:
Mean: 27
Median: 25
Range: 8
Mid Range: 28
Step-by-step explanation:
The value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.
It is given that the time in minutes for which Devi rides the bus in a week is 24, 32, 25, 24, 30, 30, 24.
We have to find out the value of mean, median, range and mid range.
What is mean of numbers ?
The mean of numbers is the ratio of sum of all numbers to the total no. of numbers.
As per the question ;
The time in minutes for which Devi rides the bus in a week is ;
24, 32, 25, 24, 30, 30, 24.
So ;
The mean will be ;
= [tex]\frac{24 + 32 + 25 + 24 + 30 + 30 +24}{7}[/tex]
= [tex]\frac{189}{7}[/tex]
= 27
and
We know that when n is odd number then ; Median is ;
= [tex]\frac{n+1}{2}th[/tex] term
= [tex]\frac{8}{2}th[/tex] term
= 4th term
= 24
and
Range will be ;
= largest number - smallest number
= 32 - 24
= 8
and
Mid range will be ;
= (largest number + smallest number) / 2
= [tex]\frac{32 + 24}{2}[/tex]
= 56 / 2
= 28
Thus , the value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.

Can someone help me please
Answer:
y= -2x + 9
Step-by-step explanation:
I got 2x because you use rise over run. As you can see in the image, the slope goes up two and to the left one ( 2x). It's plus 9 because that where it intersects the 9 on the y-intercept. The slope is negative because the line is going down from left to right ( always read it from left to right).
I hope this helps. I'm not that great at explaining so....:)
Answer:
2x+y-9=0
Step-by-step explanation:
let's take two co ordinates
(X1,y1)=(4,1)
(X2,y2)=(3,3)
Equation using two point :
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
plug in the values,(y-1)/(3-1)=(x-4)/(3-4)
(y-1)/2=(x-4)/-1
-1*(y-1)=(x-4)*2
-y+1=2x-8
0=2x+y-9
2x+y-9=0
jesse bought a car for 2,200,000 he sold for a 20% profit from the money raised from the sale he bought another more expensive car which unfortunately he had to sell for a 10% loss that was his overall profit or loss
Answer:1,76,000 Profit
Step-by-step explanation:
Given
Jesse initially bought the car for 2,200,000 and sold it for 20 %
S.P.=C.P.(1+Profit%)
so, the Selling price of the car is S.P.=[tex]2,200,000\times 1.2=2,640,000[/tex]
profit=2,640,000-2,200,000=4,40,000
After this, he bought another car and sells it for a 10 % loss
So, the selling price of the car is [tex]2,640,000\times 0.9=2,376,000[/tex]
loss=2,640,000-2,376,000=2,64,000
Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

Which of the following methods can be used to find the derivative of y = arcsin x with respect to z ?
|. Use the quotient rule to differentiate
II. Use the chain rule to differentiate sin(arcsin x) = 2.
III. Use implicit differentiation to differentiate the function y in the relation sin y = x with respect to z.
A) I only
B) Ill only
C) II and III only
D) I, II, and III
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain

13 squared plus b2 equals 18 squared. What is the answer? Please show the work.
Answer:
Solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]
Step-by-step explanation:
13 squared plus b2 equals 18 squared. What is the answer?
We can write it as:
[tex](13)^2+(b)^2=(18)^2[/tex]
Now, solving and find value of b
We know that 13² = 169
and 18² = 324
Putting values:
[tex](13)^2+(b)^2=(18)^2\\169+b^2=324[/tex]
Subtract 169 on both sides
[tex]169+b^2-169=324-169\\b^2=155[/tex]
Now, taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{155}\\b=\pm\sqrt{155}\\b=\sqrt{155},b=-\sqrt{155}[/tex]
So, solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]
A circle has a diameter of 18 feet. Which following is closest to the l circumference of the circle?
A-28.3ft
B-56.5ft
C-113.1ft
D-245.5ft
circumference =2×pi×r
18/2=9(r)
so...2×pi×9
=54..5
Answer:
56.5 ft
Step-by-step explanation:
We define the number π as the ratio between the circumference and diameter of a circle: π = c/d. Rearranging this equation gives us one for the circumference: c = πd. Using an approximation of π ≈ 3.14 and our value of d = 18 feet, we can find that c = 3.14(18) = 56.52 ft, or 56.5 ft, rounded to the nearest tenth.

Since he took 1 page of notes for each hour, and attended 33 hours of class, this will add 33 pages of notes to his notebook.
To find the total, add 8 to this, because he already had 8 pages on his own.
33 + 8

Answer:
27 minutes.
Step-by-step explanation:
R = k/t
Substituting given info
600 = k/45
k = 45 * 600 = 27000
So the relation is S = 27000/t
So if R = 1000
1000 = 27000/t
t = 27000/ 1000
t = 27.
