Step-by-step explanation:
or 2/14
Answer
7/12
Step-by-step explanation:
At one store, a 2-liter bottle of soda costs $2.12. At another store, a 3-liter bottle costs $3.15. Which bottle is a better deal? Write a division equation for each 2-liter bottle, and then decide which is the better deal.
Answer:
The 3 liter bottle has a better deal
Step-by-step explanation:
Which bottle is a better deal?
For the 2 liter bottle
At one store, a 2-liter bottle of soda costs $2.12.
2 liter bottle = $2.12
1 liter bottle = x
Cross Multiply
2x = $2.12
x = $2.12/2
x = $1.06
Hence, this is $1.06 per liter
For the 3 liter bottle
At another store, a 3-liter bottle costs $3.15.
3 liter bottle = $3.15
1 liter bottle = x
Cross Multiply
3x = $3.15
x = $3.15/3
x = $1.05
Hence, this is $1.05 per liter
Therefore, the bottle which is a better deal is the 3 liter bottle because, 1 liter goes for $1.05

In 2002, the price of mailing a letter was $.34 for the first ounce or part of an ounce and $.21 for each ounce or part of an ounce after the first ounce.
Write a rule to describe the function. How much did it cost to mail a 4-ounce letter?
A.
f(x) = 0.21(x – 1); $.63
B.
f(x) = 0.34 + 0.21x; $1.18
C.
f(x) = 0.34 + 0.21(x – 1); $.97
D.
f(x) = 0.34x + 0.21(x – 1); $1.99
Answer:
C.
f(x) = 0.34 + 0.21(x – 1); $.97
Step-by-step explanation:
In 2002, the price of mailing a letter was $.34 for the first ounce and $.21 for each ounce after the first ounce. Write a rule to describe the function.
---------------------------------------
Price = 0.34 + 0.21(x-1) where x is the weight of the item in ounces.
Let +x+ = weight of the letter in ounces
Let +P+ = the price of mailing the letter in dollars
---------------------------------------
+P+=+.34+%2B+.21%2A%28+x+-+1+%29+
( +x+%3E=+1+ )
-----------------------------
A 4-ounce letter costs
+P+=+.34+%2B++%28+4+-+1+%29%2A.21+
+P+=+.34+%2B+.63+
+P+=+.97+
It costs $.97

SOLVE RIGHT NOW PLEASE. Determine the solution to the system of equations below by using the ELIMINATION METHOD.
6x+5y=39
3x+5y=27
Answer: x=4 and y=3
Step-by-step explanation:
We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.
If Evan wants 5/8 mile to his friends house then together they walked 7/12 mile to the movie theater which pair of fractions can avenues to find how far they walked in all
Answer:
5/8 + 7/12
Step-by-step explanation:
Miles to friends house = 5/8
Ditance to the movies = 7 1/2
To find the total distance walked in Wal, we sun the fraction of distance Evans walked to his friend's house and the distance walked from friend's house to the movies ;
That is :
5/8 + 7/12
= 29/24 miles

Answer:
For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.
Step-by-step explanation:
The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).

P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left to read. How many hours of reading will Ethan have to do in order to have 14 pages left to read?
Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read
Step-by-step explanation:
Given the equation
P=-30h+74
where p =number of pages left to read and
h= the number of hours he has spent reading
Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be
P=-30h+74
14= -30h + 74
30h= 74-14
30h= 60
h = 60/30
h =2 hours
Ethan will have to spend 2 hours reading if 14 pages are left to read

The table shows the test scores and the sleep averages of several students.
a. Write the least squares regression equation that models the data. Let x = hours of sleep and y = test score.
b. Use the equation to determine the approximate test score of a student who sleeps an average of 8 h a night. Show your work.
hey someone else has already answered this!
a. To find the least squares regression equation for a group of (x,y) points:
Step 1: For each point(x,y), we need to calculate x² and xy first.
Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy
Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.
Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N
Step 5: Assemble the equation as y= mx+b
Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16
So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²
=
=
=
= 6.33
and b = Σy − m(Σx)/ N
=
=
=
= 38.71
So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71
b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35
The approximate test score of a student who sleeps an average of 8 h a night is 89.35%
EVERYTHING IS FROM sicista on brainly!
Answer:
A way to write the least regression equation that models is data y = mx + b => y= 6.33x + 38.71 and as for problem B when X = 8 then y = (6.33 x 8) + 38.71 = 50.64 = 38.71 = 89.35 so the estimated test score of a student who sleeps eight hours a night is equal to 89.39%
