The walk to the football field from our front door is 122
yards and 2 feet. What is the distance of the walk in
feet?
Answer:
368 feet
Step-by-step explanation:
122 yards converted to feet is 366, and you have to add the 2 feet from before, which makes it 368 feet.
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
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.

An angle measures 78° less than the measure of its complementary angle. What is the measure of each angle?
Answer: 6 and 84 degrees
Step-by-step explanation:
Let the measure of the angle = x.
Since complementary angles sum to 90 degrees,
x + (x+ 78) = 90
2x + 78 = 90
2x = 12
x = 6.
Therefore the angles are 6 and 84 degrees.

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
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.

Are the polygons similar? If they are, write a similarity statement. The figures are not drawn to scale.
Based on the SAS similarity theorem, both triangles are similar.
Similarity statement is: ΔSTV ~ ΔPQR by SAS Similarity Theorem.
What are Similar Polygons?Similar Polygons have different size but the same shape, and as such, the ratio of their corresponding side lengths are equal, while their corresponding angles are congruent.
Based on the SAS similarity theorem, two triangles are similar to each other if they have two pairs of corresponding sides that are proportional and an included pair of angles that are congruent.
In ΔSTV and ΔPQR:
m∠S ≅ m∠P = 86° (one pair of included congruent angles)
ST/PQ = SV/PR = 0.67 (proportional sides).
Therefore, based on the SAS similarity theorem, both triangles are similar.

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]
