Over a two hour time period a snail moved 76 inches. How far is this in yards? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
Answers
Final answer:
The snail moved a total distance of 2 1/9 yards after converting 76 inches to yards using the conversion factor of 1 yard equals 36 inches.
Explanation:
To convert the distance a snail moved from inches to yards, we use the conversion factor that 1 yard equals 36 inches. Given that the snail moved 76 inches, we divide this number by 36 to find the distance in yards.
76 inches ÷ 36 inches/yard = 2 yards and 4 inches.
Since there are 36 inches in a yard, the remaining 4 inches must be converted to a fraction of a yard by dividing by 36:
4 inches ÷ 36 = 1/9 yard.
Therefore, the snail moved 2 yards and 1/9 yard, or 2 1/9 yards in total.

Answers
$6.5s + $2d = $836.5

s = 209 - d
Plug in the values.
6.5 (209 - d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5

Answers
1/3 of 3 1/2 yd = 1/3 * 3 1/2 yd = 1/3 * 7/2 yd = 7/6 yd = 1 1/6 yd
Answer: She has 1 1/6 yd of fabric left.
Extra explanation:
You can do it two ways. I showed it to you one way. What I did above was: a whole thing is 3/3 of the thing since 1 = 1/1 = 3/3.
The entire amount she bought is one unit. It ios the same as 3/3 of what she bought. Since she used 2/3 of what she bought, she had 1/3 of what she bouht left. Then I found out what 1/3 of 3 1/2 is.
Here is a different way. She used 2/3 of what she bought, so find first what 2/3 of 3 1/2 yards is. Then subtract it from 3 1/2 yd.
2/3 * 3 1/2 = 2/3 * 7/2 = 14/6 = 7/3
3 1/2 - 7/3 = 7/2 - 7/3 = 21/6 - 14/6 = 7/6 = 1 1/6
As you can see, you still get the same answer, 1 1/6 yd left.

Answers
I = P x i x n
where I is the interest, P is the principal amount, i is the interest rate, and n is the number of years. Substituting the known values,
I = ($7000)(0.08)(1/3)
I = $186.67
Hence, the answer to this item is $186.67.
Answer:
$189.78
Step-by-step explanation:
"The computation of the interest on January 20 is shown below:
= Principal × interest rate × number of days ÷ total number of days in a year
= $7,000 × 8% × 122 days ÷ 360 days
= $7,000 × 8% × 0.338
= $189.78
The 122 days are calculated below:
September - 10 days
October - 31 days
November - 30 days
December - 31 days
January - 20 days
Total - 122 days
And we assume the 360 days in a year"

The Independent events is 0.1625.Events A and B are considered independent if the likelihood of each event's occurrence is unaffected by the occurrence of the other.
Find the independent events?P(A/B) is equal to P(A.B)/P(B) by definition (A). P(A) = P(B) / P(B) (as A, B are Independent events).
Events A and B are considered independent if the likelihood of each event's occurrence is unaffected by the occurrence of the other. P(A) = P(AB) = 1/2, which suggests that the likelihood of event A occurring has not changed as a result of the occurrence of event B.
P(0.25) = P(0.25 * 0.65) = 1/2

If you are adding two fractions that are both less than 1/2, What must be true about the sum? Give three examples to support your thinking.
Answers
if both fractions are less than 1/2 then the sum has to be less than 1
1/8 + 3/8 = 4/8 = 1/2 , less than 1
7/16 + 1/4 = 11/16, less than 1
3/16 + 1/16 = 4/16 = 1/4, less than 1
Next, add 1/2 and 1/2; the sum is 1. Thus, the two fractions must each be smaller than 1/2.
Let's try adding 5/16 and 7/16. Both are smaller than 1/2. Their sum is 12/16, or 3/4, which is less than 1.
Choose a couple other pairs of fractions which are between 0 and 1/2. Then find the sum of each pair. What do you observe about the size of these sums?

On the other hand, along the y-axis we get
[tex]\displaystyle\lim_{(x,y)\to(0,0)}\frac{x^4-20y^2}{x^2+10y^2}=\lim_{y\to0}\frac{-20y^2}{10y^2}=\lim_{y\to0}(-2)=-2[/tex]
Therefore the limit doesn't exist.
The limit of the expression as (x, y) approaches (0, 0) does not exist.
Explanation:To find the limit as (x, y) approaches (0, 0) of the expression \(\frac{x^4 - 20y^2}{x^2 + 10y^2}\), we can try approaching the limit along different paths. Let's consider approaching along the x-axis (y=0) and along the y-axis (x=0) separately.
Approaching along the x-axis: \(\lim_{{(x, 0) \to (0, 0)}} \frac{{x^4 - 20(0)^2}}{{x^2 + 10(0)^2}} = \lim_{{(x, 0) \to (0, 0)}} \frac{{x^4}}{{x^2}} = \lim_{{(x, 0) \to (0, 0)}} x^2 = 0.
Approaching along the y-axis: \(\lim_{{(0, y) \to (0, 0)}} \frac{{(0)^4 - 20y^2}}{{(0)^2 + 10y^2}} = \lim_{{(0, y) \to (0, 0)}} \frac{{-20y^2}}{{10y^2}} = \lim_{{(0, y) \to (0, 0)}} -2 = -2.
Since the limit approaches different values along different paths, the limit does not exist.

Answers
because-
252.00-114.60= 137.40
137.40+150.00= 287.40
287.40-79.68 = 207.72
207.72-161.39= 46.33
Thursday's purchase(s) total was 57.40
That exceeds her bank account total, so therefore Thursday.
Given:
Elizabeth has $252.00 in her account on Sunday and a table is given of her deposits and purchases over the following week.
To Find:
The day Elizabeth first gets charged an overdraft fee.
Answer:
Thursday's expenditure of $57.40 exceeds her bank balance at the time of transaction, and therefore Thursday is the day Elizabeth would first get charged with an overdraft fee.
Step-by-step explanation:
Elizabeth would first get charged with an overdraft fee when her expenditure exceeds her bank balance, i.e., the amount that is debited is more than what is in her bank account at that particular time.
So we analyse her transactions one by one.
On Sunday, we are given that she has $252.
On Monday, $114.60 is debited. So the remaining balance would be
$252 - $114.60 = $137.4
But on the same day, $150 is also credited to her account. So her balance would then be
$137.4 + $150 = $287.4
Next, on Tuesday, $79.68 is debited so the balance she is left with would be
$287.4 - $79.68 = $207.72
On Wednesday, $161.39 is debited so the balance she is left with would be
$207.72 - $161.39 = $46.33
On Thursday, $57.40 is debited so the balance she is left with would be
$46.33 - $57.40 = -$11.07
Thus, we see that Thursday's expenditure of $57.40 exceeds her bank balance and therefore Elizabeth would be charged with an overdraft fee as her bank balance after the transaction would be -$11.07.
A random variable x takes four possible values, 0, 2, a, and b, where a and b are unknown numbers. if pr[x = 0] = 0.2, pr[x=2] = 0.4, pr[x = a] = 0.3, e[x] = 2.8 and it is the case that a + b = 6, what is the missing value of a ?
a.-1.0
b.5.0
c.7.0
d.cannot be determined without more information
e.none of the above
Answers
Final answer:
The missing value of the random variable X can be determined by solving the equation e[x] = 2.8 and substituting the known values. By solving the equation, we find that the missing value is c. 7.
Explanation:
a. In words, X = A random variable that takes four possible values: 0, 2, a, and b.
b. X~ A missing value that represent an unknown number for the random variable X.
c. In words, X = The missing value of the random variable X, denoted by a.
d. X A missing value that we need to determine.
In this case, the missing value of a can be found by substituting the known values into the equation a + b = 6. Since b = 6 - a, we can substitute this expression into the equation e[x] = 2.8 and solve for a. From the equation, we get 0.2(0) + 0.4(2) + 0.3(a) + 0.3(6 - a) = 2.8.
Solving this equation gives us a = 7. Therefore, the missing value of a is 7, so the correct answer is c.

What is the y-intercept of the line given by the equation y = 5x - 21?
Answers
To find the y-intercept of y = 5x - 21, identify the constant term of the equation, which is -21, indicating the y-intercept is -21.
The y-intercept of the line given by the equation y = 5x - 21 can be found by analyzing the equation in the form y = mx + b, where m is the slope and b is the y-intercept.
Comparing the equation y = 5x - 21 with y = mx + b, we see that the y-intercept is -21 (b = -21).Therefore, the y-intercept of the line y = 5x - 21 is -21.A closet measure 5 feet by 3 feet does the measurement of 15 square feet show the volume inside the closet
