if your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then how many grams of dietary fiber did you eat
Step-by-step explanation:
100% = 25g
1% = 100%/100 = 25/100 = 0.25g
80% = 80×1% = 80×0.25 = 20g
If your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then 20 grams of dietary fiber you eat.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that daily value of dietary fiber is 25g.
You only ate 80% of your daily value of dietary fiber.
We have to find the amount of dietary fiber in grams you eat .
To find this we have to find the value of 80 percentage of 25.
Convert 80 % to the decimal value by dividing 80 with 100.
80/100×25
Eighty by hundred times of twenty five.
20 grams
Hence, if your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then 20 grams of dietary fiber you eat.

how do i find the formula for the nth term of the sequence 2/5, 3/4, 4/3, 5/2,... ?
Answer:
ok so first we have to find out how much each one increaces so llets just subtract the terms
3/4-2/5=0.35 so each time they add 0.35 so the nth term would be
2/5+0.35(n-1)

How do we Find a Function Value?To find the value of a function, plug in the given value of x and simplify.
Given:
m(x) = x - 7
n(x) = 1/x + 7
Find (m × n)(7)
(m × n)(7) = (x - 7)(1/x + 7)

Find the root mean square of the set 1, 3, 4, 5 and 7
Exact Answer: 2*sqrt(5)
Approximate Answer: 4.4721
====================================================
Explanation:
Original set = {1,3,4,5,7}
Square each value to get {1,9,16,25,49}. This is the list of squares.
Add up those squares: 1+9+16+25+49 = 100
Next, divide that over n = 5 which is the number of items in the set
100/n = 100/5 = 20
The value 20 is the mean of the list of squares above.
Lastly, apply the square root to get sqrt(20) = sqrt(4*5) = sqrt(4)*sqrt(5) = 2*sqrt(5)
This approximates to roughly 4.4721
--------------------
Side note: The term "root mean square" is often abbreviated to "RMS".
If we reversed the order of the three words, then we get "square mean root". In this reversed order, we see that the squaring operation is done first, then the mean next, and finally the square root is done last.
The value of the root mean square which is having sets of 1, 3, 4, 5, and 7 is 4.472.
What is a root mean square (RMS)?It is the square root of the mean square, which is the arithmetic mean of the squares of the group of values.
The formula of root mean square is given as
[tex]\rm X_{RMS} = \sqrt{\dfrac{x_1^2+x_2^2+x_3^2+....+x_n^2}{N}}[/tex]
N be the total number of observations.
The sets 1, 3, 4, 5, and 7.
Then the root mean square will be
[tex]\rm X_{RMS} = \sqrt{\dfrac{1^2+3^2+4^2+5^2+7^2}{5}}\\\\X_{RMS} = \sqrt{\dfrac{1+9+16+25+49}{5}}\\\\X_{RMS} = \sqrt{\dfrac{100}{5}}\\\\X_{RMS} = \sqrt{20}\\\\X_{RMS} = 4.472[/tex]

Answer:
x = 34
Step-by-step explanation:
An angle inscribed in a semicircle is a right angle:
3x -12 = 90
3x = 102 . . . . add 12
x = 34 . . . . . divide by 3
x-2y+3z=-1
-3x+6y-9z=3
2x-4y+6z=-2
Step-by-step explanation:
out of the first equation we get
x = 2y - 3z - 1
this we use in the second equation
-3(2y - 3z - 1) + 6y - 9z = 3
-6y + 9z + 3 + 6y - 9z = 3
0 = 0
this is the same equation as the first one, just multiplied by -3.
and we see the third equation is again the same one as the first just multiplied by 2.
so, there are infinite solutions.
this has not a single solution, as in the end this is just one equation with 3 variables.

O all real numbers
On>2 or n < 6
O 2< n < 6
Answer:
n > 2 or n < 6
Step-by-step explanation:
3 - | 4 - n | < 1
Let's move 3 to the other side of the equation:
- | 4 - n | < 1 - 3
- | 4 - n | < -2
Both sides of the equation are negative, so we can simplify by multiplying them with -1:
(- | 4 - n | < -2*-1
| 4 - n | < 2
We cannot get rid of the module because it's not for a single number and we dont know what n is equal to but there is a rule that we can use to remove the module:
- if | x | < a and a > 0 then -a < x < a. So if we use it we get the following:
- 2 < 4 - n < 2
These are two equations, separate and solve them separately
4 - n < 2
- n < 2 - 4
- n < -2
n > 2 (< turns into > because we changed sign)
and
- 2 < 4 - n
4 - n > -2
-n > -2 - 4
n < 6 (we change the sign of the numbers so the equation changes too)
So after solving the two equation we get the answers
What is the slope of the line that passes through the points (2, -4) and (5, 2)? Write
your answer in simplest form.
Answer:
Slope: 2
The slope how much y increases when x increases by 1.
Step-by-step explanation:
1. Find the difference between both y-coordinates. (6)
2. Find the difference between both x-coordinates. (3)
Divide the difference between y and x. y/x=2
The slope is 2.
Answer:
The slope of line that passes through the points (2, -4) and (5, 2) is 2.
Step-by-step explanation:
Here's the required formula to find slope line :
[tex]{\longrightarrow{\pmb{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}}[/tex]
As per given question we have provided that :
[tex]\begin{gathered}\footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf y_2 = 2\\& \sf y_1 = - 4\\ & \sf x_2 = 5\\ & \sf x_1 = 2\end{cases} \end{gathered}[/tex]
Substituting the values in the formula to find slope line that passes through the points :
[tex]\begin{gathered}\qquad{\longrightarrow{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{(2) - ( - 4)}{5 - 2}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{2 + 4}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{6}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = 2}}}\\\\\qquad{\star{\underline{\boxed{\sf{\pink{m = 2}}}}}} \end{gathered}[/tex]
Hence, the slope of line that passes through the points (2, -4) and (5, 2) is 2.

PQR Airlines reports that 90.5% of its flights arrive on time. What percent of its flights do not arrive on time?
Answer:
9.5%
Step-by-step explanation:
90.5% is the amount of flights that arrive on time, out of 100 so to find out the rest you have to minus 90.5 by 100.
90.5-100 = 9.5
90.5+9.5= 100
