Answer:
2.25 inches
Step-by-step explanation:
400+400 is 800 then 1/4 is .25 so that would make it 100 out of the 400 add that to 800 = 900 so its 2.25 inches
Please answer this 7/8 - 6/7
Answer: [tex]\frac{1}{56}[/tex].
Step-by-step explanation:
First, we need to find a common denominator. Which is 56.
So the fraction for 7/8 will be [tex]\frac{49}{56}[/tex] and 6/7 will be [tex]\frac{48}{56}[/tex].
[tex]\frac{49}{56} - \frac{48}{56} = \frac{1}{56}[/tex].
So [tex]\frac{1}{56}[/tex].

Three vertices of parallelogram DEFG are D(-2, – 4),F(0,7), and G(1,0). Find the coordinates of E.
Answer:
(-3,3)
Step-by-step explanation:
I just put the points on a graph, and counted how far away from each other they were, and found the last Point.
I hope this helps!
The coordinates of vertex E of parallelogram DEFG is: (-3, 3).
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.
Diagonals of a parallelogram bisects each other, meaning they divide each other into equal parts.
The given vertices of parallelogram DEFG are:
D(-2, – 4),F(0,7), and G(1,0)
Let (x, y) = coordinates of vertex E.
Find the coordinates of E
Find midpoint of D(-4, - 2) and F(3, 3) using :
[tex](\dfrac{-2+0}{2}, \dfrac{-4 + 7}{2}) = ( \dfrac{x + 1}{2}, \dfrac{y + 0}{2})[/tex]
[tex](-2, 3) = (x + 1, y)[/tex]
By comparison So, we have:
-2 = x + 1
x = -3
and
y = 3
Therefore, the coordinates of vertex E is: (-3, 3).

i) If 12 men can do a piece of work in 72 days. In how many days will 24 men do the same work? *
i) Find the final amount to be paid to the bank if Rs. 7000 is borrowed for 4 years at a rate of 6 % per annum. *
2 points
Answer:
Question 1 answer is 144
Step-by-step explanation:
just multiply
Answer:
1. 36 days, 2. $8,680
Step-by-step explanation:
1. We know that 12 men can do the work in 72 days, so if you add double the men, it will take half the time. Half of 72 is 36, so our answer is 36 days.
2. If $7,000 is borrowed, that person owes $7,000 so far, but they keep it for 4 years with an annual interest rate of 6%. To solve this, we need to find 6% of 7,000. To do this, we multiply 7,000 by .06. That gets us 420. Now, we multiply 420 by 4. That gets us 1,680. Now, we add 1,680 and 7,000. That gets us 8,680. That means the final amount owed is $8,680.

Step-by-step explanation:
Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.
[tex]\dfrac{x^2-16x+64}{4x^2-36x+32}=\dfrac{(x-8)^2}{4(x-8)(x-1)}=\boxed{\dfrac{x-8}{4x-4}}[/tex]
The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.

BRAINLIEST!!- Find 0.25of 40
Answer: 25% of 40 or 0.25 of 40 is 10.
Step-by-step explanation:
Basically you have to divide 40 by 10 because 1/4 of 100 is 25. 25 is 1/4 of 100.
So knowing this 40/0.25 is equal to 10. This is why 0.25 of 40 is 10.

The surface area of a cube is ...
SA = 6s²
Then the edge length is ...
54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area
9 cm² = s² . . . . . .divide by 6

Mrs. Woodworth brought 50 pies to a bake sale. She sold 42 of them and donated the rest to a local food shelter. What percent of the pies did she sell?
Answer:
the percent of the pies did she sell is 84%
Step-by-step explanation:
The computation of the percent of the pies did she sell is as follow;
= Number of pies sold ÷ total number of pies purchased
= 42 ÷ 50
= 84%
Hence, the percent of the pies did she sell is 84%
We simply divided by the number of pies sold from the total number of pies purchased so that the selling percentage could come

the observations 7,15,x-1,x+1,24,28 have been arranged in ascending order. if the median of the data is 21. find the value of X.
Answer:
x = 21
Step-by-step explanation:
The following data were obtained from the question:
Set of data => 7, 15, x–1, x+1, 24, 28
Median = 21
x =?
Median is simply defined as the middle term of a given data arranged either in ascending or descending order.
Next, we shall determine the median of the set of data. This can be obtained as follow:
7, 15, x–1, x+1, 24, 28
Median = [(x–1) + (x+1)]/ 2
Finally, we shall determine the value of x as follow:
Median = [(x-1) + (x+1)]/ 2
Median = 21
21 = [(x-1) + (x+1)]/ 2
21 = [x – 1 + x + 1] /2
21 = [x + x – 1 + 1] /2
21 = 2x / 2
21 = x
Thus, x is 21
****Check****
Median = 21
x = 21
Median = [(x–1) + (x+1)] / 2
21 = [(21 – 1) + (21 + 1)] / 2
21 = [20 + 22] / 2
21 = 42/2
21 = 21

Give the domain and range of the relation.
Answer:
(a) D: {-5, 0, 4, 6}; R: {-9, 0, 9, 13}
Step-by-step explanation:
The domain is the list of values in the x-column.
The range is the list of values in the y-column.
It is useful, but not essential, that the values be listed in numerical order.
x-values are 4, 6, 0, -5, so we can say the domain is {-5, 0, 4, 6}
y-values are 9, 13, 0, -9, so we can say the range is {-9, 0, 9, 13}

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards without replacement from a standard deck. If both cards are diamonds, your friend will pay you $810. Otherwise, you have to pay your friend $49. Step 2 of 2 : If this same bet is made 914 times, how much would you expect to win or lose
Answer:
Step-by-step explanation:
We all know that there are 52 cards prszent in a deck out of which 13 are diamonds. Hence, the probability that both cards are spade is
13/52 * 12/51 =
0.25 * 0.235 =
0.0588
If both cards turn out to be diamonds, the friend pays $810 which is
$810 * 0.0588 = $47.628
On the other hand, the probability that both cards isn't a diamond is simply the negation of the probability that it is a diamond.
1 - 0.0588 = 0.9412
And you would have to pay your friend
$49 * 0.9412 = -$46.12, with the prefixed negative sign telling us that it's a lost bet.
