Questions 1, 2, and 5 are correct.
Question 3:
To find the common difference, we can subtract the last two numbers.
60 - 47 = 13
So, the common difference is 13
We can add 13 to each term to get the next term.
8 + 13 = 21
21 + 13 = 34
So, 8, 21, 34, 47, 60
Question 4:
To find the common difference, we can subtract the last two numbers.
8/3 - 2 = 2/3
So, the common difference is 2/3
We can add 2/3 to each term to get the next term.
0 + 2/3 = 2/3
2/3 + 2/3 = 4/3
So, 0, 2/3, 4/3, 2, 8/3
Question 4:
Since we are only given the first and last number, we need to find a number we can subtract that we get -13 at the end. The distance between 3 and -13 is 16. We can divide this by 4 since there are 4 numbers before -13.
16 / 4 = 4
Since the number is going down, the common difference is going to be -4.
Subtract find the next terms.
3 - 4 = -1
-1 - 4 = -5
-5 - 4 = -9
-9 - 4 = -13
So, 3, -1, -5, -9, -13

11. What is the difference between the weights of planes C and D? Explain how to use mental math to solve. - C: 56,984 D: 79,473 - The difference in weights is ______ pounds. The difference in weights is given by the expression _______ - _______. Compensation can be used to rewrite this so that the second number is the next greater multiple of 1,000. Doing this gives the new expression ______ - ______. The value of this new expression is _____________. (Type whole numbers.)
Answer:
22,48979,473 - 56,98479,489 - 57,00022,489Step-by-step explanation:
Based on the clues in the problem wording, we assume the numbers given for C and D are the weights of planes, in pounds. For whatever reason, we seem to be interested in the difference of those weights.
The difference in weights is 22,489 pounds.
The difference in weights is given by the expression 79,473 - 56,984.
We can add 16 to both numbers to make the second number a multiple of 1000. To compensate, we also add 16 to the first number.
Doing this gives the new expression 79,489 - 57,000.
The value of this expression is 22,489.
_____
Additional comments
A number of thinking processes are taught for mental math. In this process, you recognize that 984 is near 1000, so you can add a small number to make all the rightmost digits be zeros. That number will have the digits that "make a ten" working from right to left. 4 needs 6 added to make a 10. Adding 6 to 84 makes it 90. Then the 9 needs 1 added to make a 10. Now, we have 984 with 16 added, which makes 1000. Adding that 16 to 79473 to make 79489 completes the transformation we're looking for: 79489 -57000.

Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (4, −5, 2) and parallel to the line x + 5 = y 2 = z − 3
Answer:
Step-by-step explanation:
From the given information, the symmetric equations for the line pass through(4, -5, 2) i.e ([tex]x_o, y_o, z_o[/tex]) and are parallel to [tex]\dfrac{x+5}{1} = \dfrac{y}{2}= \dfrac{z-3}{1}[/tex]
The parallel vector to the line i + zj+k = ai + bj + ck
Hence, the equation for the line is :
[tex]x = x_o + at \\ \\ x = y_o + bt \\ \\ x = z_o + ct[/tex]
x = 4 + t
y = -5 + 2t
z = 2 + t
Thus, x, y, z = ( 4+t, -5+2t, 2+t )
The symmetric equation can now be as follows:
[tex]\begin {vmatrix} x = 4+ t \\ \\ \dfrac{x-4}{1} = t \begin {vmatirx} \end {vmatrix}[/tex][tex]\begin {vmatrix} y = - 5+2t \\ \\ \dfrac{y+5}{2} =t \end {vmatrix}[/tex][tex]\begin {vmatrix} z =2+t \\ \\ \dfrac{z-2}{1} =t \end {vmatrix}[/tex]
∴
[tex]\dfrac{x-4}{1}= \dfrac{y+5}{2}=\dfrac{z-2}{1}[/tex]

In June 2011, CBS News and the New York Times reported the results of a poll about problems and priorities for the U.S. In the poll, 979 U.S. adults answered the question, “What do you think is the most important problem facing this country today?” From a list of options, 53% of those polled said “economy/jobs.” This is an observational study designed to answer a question about a population. Who is the population?
Answer: All adults of United States.
Step-by-step explanation:
A population is a large community of individuals that share some same characteristic or root.Here, the study is all about the problem have been facing by the population of U.S.
Since adults of a society are likely voters.
So, population = All adults of United States., as only they can address the current situation or problems because they live there.

Step-by-step explanation:
A linear pair is two angles that are adjacent and the non-common sides form a straight line.
Answer:
They are supplementary
Step-by-step explanation:
A linear pair is two angles ajacent. The non - common side forms a straight line. So the angles added together are equal to 180 degrees.
What is the empirical formula of an oxide of chromium that is 48 percent oxygen by mass?
Answer:
CrO₃.
Step-by-step explanation:
We'll begin by calculating the percentage of chromium in the oxide. This can be obtained as follow:
Oxygen (O) = 48%
Chromium (Cr) =?
Oxide of chromium contains only chromium and oxygen. Therefore, the percentage of chromium in the oxide is given by:
Cr = 100 – percentage of oxygen
Cr = 100 – 48
Cr = 52%
Finally, we shall determine the empirical formula of the oxide as follow:
Chromium (Cr) = 52%
Oxygen (O) = 48%
Divide by their molar mass
Cr = 52/52 = 1
O = 48/16 = 3
Divide by the smallest
Cr = 1/1 = 1
O = 3/1 = 3
Therefore, the empirical formula of the oxide is CrO₃.

Can you explain how to do these three problems?
Step-by-step explanation:
a) The distance is the integral of the velocity vs. time graph. We can approximate the distance using a left hand Riemann sum. That means for each interval, use the velocity at the beginning of the interval. Don't forget to convert mi/hr to mi/s.
d₁ = (10 s − 0 s) (183.9 mi/hr × 1 hr / 3600 s) = 0.5108 mi
d₂ = (20 s − 10 s) (169.0 mi/hr × 1 hr / 3600 s) = 0.4694 mi
d₃ = (30 s − 20 s) (105.6 mi/hr × 1 hr / 3600 s) = 0.2933 mi
d₄ = (40 s − 30 s) (99.8 mi/hr × 1 hr / 3600 s) = 0.2772 mi
d₅ = (50 s − 40 s) (124.5 mi/hr × 1 hr / 3600 s) = 0.3458 mi
d₆ = (60 s − 50 s) (177.1 mi/hr × 1 hr / 3600 s) = 0.4936 mi
d = 0.5108 + 0.4694 + 0.2933 + 0.2772 + 0.3458 + 0.4936
d = 2.390 miles
b) Do the same as part a, but this time, use a right hand Riemann sum. Instead of using the velocity at the beginning of the interval, use the velocity at the end of the interval.
d₁ = (10 s − 0 s) (169.0 mi/hr × 1 hr / 3600 s) = 0.4694 mi
d₂ = (20 s − 10 s) (105.6 mi/hr × 1 hr / 3600 s) = 0.2933 mi
d₃ = (30 s − 20 s) (99.8 mi/hr × 1 hr / 3600 s) = 0.2772 mi
d₄ = (40 s − 30 s) (124.5 mi/hr × 1 hr / 3600 s) = 0.3458 mi
d₅ = (50 s − 40 s) (177.1 mi/hr × 1 hr / 3600 s) = 0.4936 mi
d₆ = (60 s − 50 s) (175.6 mi/hr × 1 hr / 3600 s) = 0.4878 mi
d = 0.4694 + 0.2933 + 0.2772 + 0.3458 + 0.4936 + 0.4878
d = 2.367 miles
c) The velocity decreases from 0 s to 30 s, but then increases from 30 s to 50 s, and then decreases from 50 s to 60 s.
Since the velocity doesn't consistently increase or decrease, these Riemann sums are neither lower nor upper sums.
frank liked to buy packs of baseball cards. on 3 different days, he bought 3 packs. on 3 other days, he bought 4 packs each day. After that he splits his packs with his 2 brothers. How many packs will they each have. Choose the expression that best matches this situation.
Answer:
First, frank buys 3 packs on 3 different days, so in those first 3 days he buys:
3*3 = 9 packs.
Then on other 3 days he buys 4 packs each day, so he has:
3*4 = 12 packs.
In total he haves:
9 + 12 = 21 packs.
Now he divides the packs with his 2 brothers (So we divide 21 packs between 3 people)
Then each brother gets:
N = 21/3 = 7 packs each.
Which of the following represents “ 10 times the sum of a number and 14 is equal 9 times the number”?
Answer:
The expressión is:
10(a+14) = 9a
and the number is:
-140
Step-by-step explanation:
The expression is:
10(a+14) = 9a
then:
10*a + 10*14 = 9a
10a + 140 = 9a
10a - 9a = -140
a = -140
Check:
10(-140+14) = 9*140
10*-126 = 1260

If the aspect ratio in width to height (width: height) of a chalkboard is 46:30 and the width is 170 inches, what is the height of the chalkboard? 5,100 in 30 in 46 in 260.6 in
Answer:
110.7 inches
Step-by-step explanation:
Width : Height ( 46:30 )
Width is 46 and Height is 30
So 46 = 170 inches
1 = ?
1 = 170/46
=3.69 inches.
To know the height, multiply that(3.69) with 30. And you will get the inches of the height which is "110.7 inches"
On Thursday, a local hamburger shop sold a combined total of 234 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Thursday?
Hey there! I'm happy to help!
Let's call the hamburgers h and the cheeseburgers c.
h+c=234
c=2h
Let's plug this value of c into the first equation to solve for h.
h+2h=234
3h=234
Divide both sides by 3.
h=78
Therefore, 78 hamburgers were sold on Thursday.
Have a wonderful day! :D
Write an equation in slope-intercept form (y = mx + b).
Parallel to 3x + 5y = 18 passing through (-10, -4).
Answer:
y= [tex]\frac{-3}{5}x -2[/tex]
Step-by-step explanation:
find the gradient by rearranging the equation, y= [tex]\frac{-3}{5}x[/tex] +[tex]\frac{18}{5}[/tex]
from here we can see that the slope or gradient is [tex]\frac{-3}{5}x[/tex]
now using the equation y-y2 = f'(x1)(x-1) we find the equation by subbing
= y- (-4) = [tex]\frac{-3}{5}[/tex] (x - [-10])
= y + 4 = [tex]\frac{-3}{5}x -6[/tex]
= y= [tex]\frac{-3}{5}x -2[/tex]
