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

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.
HOT AIR BALLOON A balloon rises
340 feet into the air. Then it descends
130 feet
PLEASE ANSWER I REALLY NEED IT
Answer:
it is at 210 feet
Step-by-step explanation:
it rises 340 feet, then it descends 130 so we subtract 130 from 340 which gets us 210 feet.
If x = −5, which number line shows the value of |x|?
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.

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]

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:
Step-by-step explanation:
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°

You win an online auction for a toy. Your winning bid of $60 is 75% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
The maximum amount of bid for the toy will be equal to $80.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that you win an online auction for a toy. Your winning bid of $60 is 75% of your maximum bid.
The maximum bid will be calculated as,
Maximum bid = ( 100 x 60 ) / 75
Maximum bid = $80
Therefore, the maximum amount of bid for the toy will be equal to $80.

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]
