Answer:
25/44
Step-by-step explanation:
-0.8x+40-8x-35
-8.8x+5
-8.8x=-5
Minus sign cancel on both side
X=5/8.8
X=50/88
X=25/44
So value of x is 25/44

Answer:
G > F > H
Step-by-step explanation:
In a triangle, the largest side and largest angle are opposite eachother. Similarly, the smallest side and smallest angle are opposite eachother.
We have 3 sides of length 6 cm, 11 cm, and 12 cm. The angle opposite the 6 cm side is the smallest (H). The angle opposite the 14 cm side is the largest (G).
What is a solution to (x + 6)(x + 2) = 60?
Answer:
x=4 or -12

Penny Weights, use the weights of the post 1983 pennies to construct a 98% confidence interval estimate of the standard deviation of the weights of all post-1983 pennies. S=0.0165 n=37. Find confidence interval. a. 0.01231 < Ï < 0.2111 b. 0.01239 < Ï < 0.02111 c. 0.1391 < Ï < 0.2311 d. 0.001219 < Ï < 0.002111
Answer:
c. 0.1391 < Ï < 0.2311
Step-by-step explanation:
The formula for Confidence Interval is given as:
Mean ± z × Standard deviation/√n
Z score for 98% confidence interval = 2.326
Mean = Significance level = 100% - 98%
= 2% = 0.02
Standard deviation = S=0.0165
n= 37
Hence,
Confidence Interval =
0.02 ± 2.326 × 0.0165/√37
0.02 ± 0.0063094687
Confidence Interval
0.02 - 0.0063094687
= 0.1391
0.02 ± 0.0063094687
= 0.2311
Hence, the Confidence Interval = (0.1391, 0.2311)
= c. 0.1391 < Ï < 0.2311
Arrow is planning to bake approximately 305 cookies. If 3 pounds of cookie dough make 96 cookies, how many pounds of cookie dough should he make?

X+2y=-9
Solve for Y km
Answer:
y = - 1/2x - 4.5
Step-by-step explanation:
Step 1:
x + 2y = - 9 Equation
Step 2:
2y = - x - 9 Subtract x on both sides
Answer:
y = - 1/2x - 4.5 Divide 2 on both sides

Questions in the picture
Answer:
This is not a function. This is because if there are any repeating x values (the first values of each set) it is not a function. It is okay for there to be repeating y values (the second values of each set) but not x values.
Step-by-step explanation:
I am guessing the question is if this is a function.

Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1
Answer:
perpendicular
Step-by-step explanation:
3y = x + 4 in slope intercept form y = 1/3x +4/3
3x + y = 1 in slope intercept form y = -3x +1
the slopes are negative reciprocals of each other so they are perpendicular
Answer:
These lines are perpendicular
Step-by-step explanation:
3y=x+4
[tex]y = \frac{1}{3}x+\frac{4}{3}[/tex]
Slope (m1) = 1/3
3x+y=1
y = -3x + 1
Slope (m2) = - 3
m1 * m2 = [tex]\frac{1}{3}* -3[/tex]
= -1
So, these lines are perpendicular.
If product of two slopes is (-1), then they are perpendicular lines.
If both lines have same slope, then they are parallel.

Zoe just lit a new candle and then let it burn all the way down to nothing. The length
of the candle remaining unburned, in inches, can be modeled by the equation
L = 9 – 0.5t, where t represents the number of hours since the candle was lit.
What is the y-intercept of the equation and what is its interpretation in the context of
the problem?
Answer:
9 which represents the the original length of the new candle
Step-by-step explanation:
Since there were 9 inches of candle remaining after 0 hours of burning, that means 9 represents the initial length of the candle, in inches.

Olivia typed 2 pages in 12 minutes. How long will it take her to type 10 pages at this rate?
Answer:
60
Step-by-step explanation:
If Olivia typed 2 pages in 12 minutes, this means that she can type 1 page in 6 minutes. Since we're looking for the amount of time it would take her to type 10 pages, we multiply 6 by 10 to get 60.
Answer:
60 minutes
Step-by-step explanation:
if Olivia writes 2 pages in 12 minutes that means she writes 1 page in 6 minutes. 6 minutes per page times 10 pages equals 60 minutes for 10 pages.
