Determine whether the sequence 12, 40, 68, 96 could be geometric or arithmetic. If possible, find the common ratio or difference.
a
It could be arithmetic with d = 28.
b
It could be arithmetic with d = –28.
c
It could be geometric with r = 28.
d
It is neither.
Answer:
A
Step-by-step explanation:
it is Arithmetic because if you subtract 12 from 40 you'll get 28 , same for the others. but if you get the common ratio by dividing 40/12 which is 3.333... it's doent work for the sequence

Monic and Rachel purchased a tv for $378. Monica paid $36 less then Rachel. How many did each person pay for the tv? Solve using substitution or elimination. Plz answer quick
Answer:
Monica paid $171 while Rachel paid $207
Step-by-step explanation:
We are told that Monic and Rachel purchased a tv for $378.
Let the amount spent by Monica be X and the amount spent by Rachel be Y.
Thus;
x + y = 378 - - - - (eq 1)
We are told that Monica paid $36 less then Rachel. Thus;
y = x + 36
Or y - x = 36 - - - (eq 2)
Add eq 1 & eq 2 together to give;
2y = 378 + 36
2y = 414
y = 414/2
y = $207
Put 207 for x in eq 1 to get;
x + 207 = 378
x = 378 - 207
x = $171
Thus;
Monica paid $171 while Rachel paid $207

of mlln, line AC ll line BD, and m angle 3 - 108, what is the measure of angle 7
Answer:
A) 72
Step-by-step explanation:
Okay well sice the lines AC and BD are parrallel that tells you that angles 4 is equal to 7 and angle 3 is equal to 8. Knowing this helps, now angle 3 and 4 have to equal 180 degrees cause it a strioght line. so do 180 - 108 (angle 3) equals angle 4. Once you find angle 4 degrees its the same as angle 7.

Brett shaded 4/8 of a sheet of notebook paper. Aisha says he shaded 1/2 of the paper. Are the two fractions equivalent? if so, what is another equivalent fraction
Answer:
The two fractions are equivalent; another equivalent fraction is 3/6
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] x 4 = 4/8, therefore the fractions are equivalent.
1/2 x 3 = 3/6 which is equivalent to 1/2.
Approximate √10 to the nearest whole number
Answer:
3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Since square rooting (√) is the opposite function of squaring a number (exponent of 2), to approximate √10 to the nearest whole number, determine the two squares it is in between.
If you square 3, you will get 9 (3 x 3 = 9) and if you square 4, you will get 16 (4 x 4 = 16). Since 10 is in between 9 and 16, √10 will be in between 3 and 4.
The difference between 9 and 10 is only 1, while the difference between 10 and 16 is 6. Therefore, √10 is closest to 3.

CAN ANYONE HELP ME ASAP? I WILL GIVE BRAINLIEST!
Answer/Step-by-step explanation:
According to the centroid theorem, the X is ⅔ of the distance from each vertex to the midpoint of the opposite side.
Thus:
1. If CW = 15,
CX = ⅔*(15)
CX = 10
XW = ⅓*(15)
XW = 5
2. If BX = 8,
BX = ⅔*BY
3*BX = 2*BY
(3*BX)/2 = BY
(3*8)/2 = BY
24/2 = BY
12 = BY
BY = 12
XY = ⅓*BY
XY = ⅓*12
XY = 4
3. If XZ = 3, find AX and AZ.
XZ = ⅓*AZ
XZ*3 = AZ
3*3 = AZ
9 = AZ
AZ = 9
AX = ⅔*AZ
AX = ⅔*9
AX = 6

36 • (-9)
SHOW WORK PLEASE!!!
Answer:
-324
Step-by-step explanation:
First, you need to just multiply the two numbers together.
36 * 9
This would give you the overall answer. Then you determine if when you multiply the numbers, if you'd need to add the integer, a.k.a, the negative sign.
Since when you multiply a negative and a positive, the answer will be negative.
So, 36 * (-9) = -324

How much more expensive is it, per pound, to buy ground beef at Store B than at Store A?
Answer:
2.42
Step-by-step explanation:
First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.
Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.
Y1-15.54=10.36x -15.54 get y1 by itself
Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42
