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?
Answer: 10
Step-by-step explanation: 96 divided by 3 is 32
32 x 10 = 320 you can't get exactly 305.
The amounts of e-waste generated in a region during two years were 14,200,000 tons and 10,700,000 tons. What was the total e-waste generated over these two years in the region, expressed in scientific notation? (5 points)
9514 1404 393
Answer:
2.49×10^7
Step-by-step explanation:
14,200,000 +10,700,000 = 24,900,000 = 2.49×10,000,000
= 2.49×10^7

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).
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.

Property of an isosceles triangle,
Opposite angles of the equal sides in an isosceles triangle are equal in measure.
m∠D = m∠F
(2x + 8) = (3x + 4)
3x - 2x = 8 - 4
x = 4
m∠D = m∠F = (3×4 + 4)°
= 16°
m∠D = m∠F = 16°
Since, sum of interior angles of a triangle = 180°
m∠D + m∠E + m∠F = 180°
16° + m∠E + 16° = 180°
m∠E = 180° - 32°
m∠E = 148°
A search committee is formed to find a new software engineer.
a) if 100 applicants apply for the job, how many ways are there to select a subset of 9 for a short list?
b) If 6 of the 9 are selected for an interview, how many ways are there to pick the set of people who are interviewed?
c) Based on the interveiw, the committe wil rank the top three candidates and submit the list to their boss who will make the final decision. How many ways are there to select the list from the 6 interviews?
Answer:
(a) 1,902,231,808,400
(b) 84
(c) 20
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\cdot(n-k)!}[/tex]
(a)
Compute the number of ways to select 9 applicants from 100 as follows:
[tex]{100\choose 9}=\frac{100!}{9!\cdot(100-9)!}[/tex]
[tex]=\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400[/tex]
(b)
Compute the number of ways to select 6 people from 9 as follows:
[tex]{9\choose 6}=\frac{9!}{6!\cdot(9-6)!}[/tex]
[tex]=\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84[/tex]
(c)
Compute the number of ways to select top 3 candidates from 6 as follows:
[tex]{6\choose 3}=\frac{6!}{3!\cdot(6-3)!}[/tex]
[tex]=\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20[/tex]
Need help finding the parallel and perpendicular slope
Answer:
Step-by-step explanation:
(x₁, y₁) = (19 , -4) & (x₂ ,y₂) = (17, -20)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{-20-[-4]}{17-19}\\\\= \frac{-20+4}{17-19}\\\\= \frac{-16}{-2}\\\\= 8[/tex]
m = 8
Parallel lines have same slope.
Parallel slope = 8
Slope of perpendicular line = [tex]\frac{-1}{m}[/tex]
Perpendicular slope = [tex]\frac{-1}{8}[/tex]
Slope intercept form of equation
Answer:
slope= 5/3 y-intercept=3
Step-by-step explanation: Equation= y=5/3x+3

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.

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

Answer:
B. -4, -3
Step-by-step explanation:
The equation x^(2) + 7x + 12 can be factored using the AC method resulting in
( x + 4 )( x + 3 ). So x = -4, -3. You can use foil to check.
Find the next three terms of the following arithmetic sequence -2, -5, -8, -11,
Answer: -14, -17, and -20
Step-by-step explanation: Study the sequence.
Notice that each number is 3 less than the number before it.
In other words, -2 - 3 is -5, -5 - 3 is -8, and -8 - 3 is -11.
Now, if we continue with this same sequence,
-11 - 3 is -14, -14 - 3 is -17, and -17 - 3 is -20.
So the next three numbers are -14, -17, and -20.

Answer:
It is the second circle I believe
Step-by-step explanation:
As you can see on the x side is always just going up 1, and the y side is 2 numbers behind the x side in the beginning. But the y side catches up to the x side, which you can see once the x and y side both have positive 1's. The the y side goes up 2 more while the x side only goes up once.
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.

what is the least number of degrees you could rotate a square around its center so that it appears to be unchanged?.
Answer:
Does a square have rotation symmetry? Yes, a square can be rotated \begin{align*}90^\circ\end{align*} counterclockwise (or clockwise) about its center and the image will be indistinguishable from the original square.
Step-by-step explanation:
Answer:
90°
Step-by-step explanation:
If you rotate a square about its axis, in 90°, 180°, 270°, 360°, ... degrees, it looks to be the same.
