What is the common difference for this arithmetic sequence?
31, 48, 65, 82, ...
Answer:
d = 17
Step-by-step explanation:
The given arithmetic sequence is :
31, 48, 65, 82, ...
We need to find the common difference for this sequence.
First term, a₁ = 31
Second term, a₂ = 48
Common difference = a₂-a₁
= 48-31
= 17
So, the common difference for this arithmetic sequence is equal to 17.
Estimate the difference

What is 5/9 - 3/8?
Here's how to subtract 3/8 from 5/9:
5
9
−
3
8
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 5 by 8, and get 40.
Then we multiply 3 by 9, and get 27.
Next we give both terms new denominators -- 9 × 8 = 72.
So now our fractions look like this:
40
72
−
27
72
Step 2
Since our denominators match, we can subtract the numerators.
40 − 27 = 13
So the answer is:
13
72
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
Nope! So now we try the next greatest prime number, 13...
Nope! So now we try the next greatest prime number, 17...
No good. 17 is larger than 13. So we're done reducing.
There you have it! The final answer is:

Find 50% of 36:
Find 25% of 36:
Find 75% of 36:
Answer:
18, 9, 27
Step-by-step explanation:
36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.
36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.
Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.
what Is the answer to 1/6 + 2/3
Answer:
5/6
Step-by-step explanation:
When adding fractions, you must ensure the denominator is the same in both fractions.
In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.
When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.
2/3 × 2/2 = (2×2)/(3×2) = 4/6
Replace 2/3 with its equivalent 4/6.
Now you will add the numerators together.
1/6 + 4/6 = (1+4)/6 = 5/6
Your final answer is 5/6
Answer:
5/6
Step-by-step explanation:
2/3--> 4/6 (GCF)

Answer:
Solution:
The greatest of Winnie's even numbers is $2\times 30 = 60,$ so her sum is
\[2+4+6+\cdots + 58 + 60.\]For Grogg's sum, there are five odd numbers between $0$ and $-10$, five between $-10$ and $-20$, and so on, so Grogg's sum is
\[(-1)+(-3)+(-5)+\cdots+(-57)+(-59).\]
We could compute these sums separately and find their difference, but instead, we'll look for a clever way to regroup to compute the difference
\[(2+4+6+\cdots +58+60)-((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Noting that Winnie's list steps up by 2 at each term while Grogg's steps down by 2 at each step, we write Winnie's list backwards, so that each list goes down by 2 at each step:
\[(60+58+56+\cdots + 4+2) - ((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Now, we see that the difference between a term in Winnie's backwards list and the corresponding term in Grogg's list is always the same:
\begin{align*}
60-(-1) &= 61,\\
58-(-3) &= 61,\\
56-(-5) &=61,\\
\vdots&\\
2-(-59) &= 61.
\end{align*}There are 30 such differences, so Winnie's sum is $30\times 61 = \boxed{1{,}830}$ greater than Grogg's sum.

Suppose that 11 inches of wire costs 33 cents. At the same rate, how many inches of wire can be bought for 18 cents?
Answer:6 inches
Step-by-step explanation:
11inch=33 cents
1 cent can buy 11/33= 1/3 inches
18 cents can buy 18 * 1/3 = 6 inches
Answer:
6in. = 18 cents
Step-by-step explanation:
1. Find out how many inches it costs for one inch ( 33/11 = 3)
2. divide 18 by 3 and get 6.

what is the value of d/dx(1/x) at x=6 ?
If you know your derivative rules, then
d/dx [1/x] = -1/x ²
so that when x = 6, the derivative has a value of -1/36.
If you have to use the definition of the derivative, then
d/dx [1/x] = lim {h → 0} (1/(x + h) - 1/x) / h
… = lim {h → 0} (x - (x + h)) / (hx (x + h))
… = lim {h → 0} (-h) / (hx (x + h))
… = lim {h → 0} (-1) / (x (x + h))
… = -1/x ²
and at x = 6, you again get -1/36.
Alternatively, use the definition of the derivative at a point:
d/dx [1/x] (6) = lim {x → 6} (1/x - 1/6) / (x - 6)
… = lim {x → 6} ((6 - x) / (6x)) / (x - 6)
… = lim {x → 6} -(x - 6) / (6x (x - 6))
… = lim {x → 6} (-1) / (6x)
… = -1/36

I need help is this complementary supplementary or nither
Answer:
The answer is supplementary angles.
Step-by-step explanation:
Identify the angle pair as complementary or supplementary.
If one angle is 60 degrees and the other angle is 120 degrees.
First, add the two angles together to find the sum.
60 + 120 = 180
Then, identify which angle pair adds up to 180 degrees.

A mug is 3/7 full. The mug contains 4/7 of a cup of water. Find the capacity of the mug.
Answer:
7/6 cups
Step-by-step explanation:
Mug is 2/7 full
Amount of water in the mug = 1/3 cup
Assume the full capacity of the mug = m
Then the current capacity of water in mug = (2/7) of m = (2/7)m
Current capacity of water in mug is equivalent to 1/3 cup of water
Hence,
(2/7)m = 1/3
2m/7 = 1/3
Cross multiply
(2m * 3) = 7 * 1
6m = 7
m = 7/6
m = 1 1/6 cups

Between 10 P.M. and 7:45 A.M., the water level in a swimming pool decreased by 3/8 inches . Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answer:
0.03846154... inches/hour
Step-by-step explanation:
between 10 P.M. and 7:45 A.M. = 9.75 hours
(3/8) inches / 9.75 hours = 0.03846154... inches per hour
EDIT: in fraction form
Answer:
1/26 inches/hour
Step-by-step explanation:
between 10 P.M. and 7:45 A.M. = 9 and 3/4 hours, or 39/4 hours
(3/8) inches / (39/4) hours = 1/26 inches per hour
