The 28.3 feet high above the ground are the windows on the third story of the house.
It is required to find the height.
What is the Pythagorean Triple?The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:
c² = a² + b².
Given that:
Distance between ladder and wall=25 feet
Height of window=20 feet
Closer distance between ladder and wall=15 feet
We know the Pythagoras theorem , we get
[tex]a^{2} +b^{2} =c^{2}[/tex]
we have
a=15 feet
b=?
c=25 feet
So,
[tex]a^{2} +b^{2} =c^{2}\\\\15^{2} +b^{2} =25^{2}\\\\225+b^{2} =625\\\\b^{2}=625-225\\\\b^{2}=400\\\\b=20 feet[/tex]≈28.3 feet
Therefore, the 28.3 feet high above the ground are the windows on the third story of the house.

Work out m and c for the line: y = 7 − x
The line y = 7 − x has a slope(m) of - 1 and y-intercept b is 7.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, an equation of a line y = 7 - x.
We can rearrange this in the form of slope-intercept form which is
y = mx + b.
y = - x + 7.
y = (-1)x + 7.
The slope (m) of this line is - 1 and the y-intercept(b) is 7.

Find the Area of the figure below, composed of a rectangle with a semicircle
removed from it. Round to the nearest tenths place.
Answer:
Area of the figure = 25.7 units²
Step-by-step explanation:
Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD
Area of the rectangle ABCD = Length × Width
= BC × AB
= 8 × 4
= 32 units²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
r = [tex]\frac{\text{Diameter}}{2}[/tex]
r = [tex]\frac{1}{2}(CD)[/tex]
r = [tex]\frac{4}{2}[/tex]
r = 2 units
Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]
= 2π
= 6.28 units²
Area of the given figure = 32 - 6.28
= 25.72 units²
≈ 25.7 units²

Write the number in scientific notation. 0.00000625
The number 0.00000625 in scientific notation is [tex]6.25\times 10^{-6}[/tex].
To write the number 0.00000625 in scientific notation, we can follow these steps:
First Move the decimal point to create a number between 1 and 10.
In this case, we can move the decimal point 6 places to the right to obtain 6.25.
Count the number of places moved to determine the exponent.
Since we moved the decimal point 6 places to the right, the exponent will be -6.
Write the number in scientific notation.
0.00000625 can be written as [tex]6.25\times 10^{-6}[/tex].
Therefore, the number 0.00000625 in scientific notation is [tex]6.25\times 10^{-6}[/tex].

Naitik exercised for
2/3 hours ,while Aryan exercised for
3/4
hours.Who
exercised for a longer time? step by step answer
=======================================================
Explanation:
Use your calculator to convert each fraction into decimal form
2/3 = 0.67 approximately
3/4 = 0.75 exact
The decimal 0.75 is larger than 0.67, in which we can think of it like saying "75 is larger than 67".
So 0.67 < 0.75 which leads to 2/3 < 3/4.
Aryan spent more time exercising.
--------------
We could stop there, but if you wanted to know how much longer he spent exercising, then we subtract the two fractions to get
3/4 - 2/3
9/12 - 8/12
(9-8)/12
1/12
Aryan spent 1/12 of an hour longer exercising compared to Naitik
1/12 hour = (1/12)*60 = 60/12 = 5 minutes
He spent 5 extra minutes exercising.

Notes:
2/3 hours = (2/3)*60 = 40 minutes3/4 hours = (3/4)*60 = 45 minutes45-40 = 5 extra minutes of exerciseNo random answers or links, please.

OVER 300
STUDENTS
WANT TO
START AFTER
8:00 AM
A
Supported
Not Supported
Answer:
Over 300 students did not support start time after 8:00am
Step-by-step explanation:
Given
[tex]N = 600[/tex] --- population
[tex]n = 40[/tex] --- sample
See attachment for dataset
Required [True/False]
Over 300 wants start time after 8:00am
First, we calculate the number of samples that wants start time after 8:00am
[tex]x = 8:30am\ start + 9:00am\ start[/tex]
For sample 1
[tex]x_1 = 18[/tex]
The corresponding value of x1 in the overall population is:
[tex]X_1 = \frac{x_1}{n} * N[/tex]
[tex]X_1 = \frac{18}{40} * 600[/tex]
[tex]X_1 = \frac{18 * 600}{40}[/tex]
[tex]X_1 = \frac{10800}{40}[/tex]
[tex]X_1 = 270[/tex]
For sample 2
[tex]x_2 = 19[/tex]
The corresponding value of x2 in the overall population is:
[tex]X_2 = \frac{x_2}{n} * N[/tex]
[tex]X_2 = \frac{19}{40} * 600[/tex]
[tex]X_2 = \frac{19* 600}{40}[/tex]
[tex]X_2 = \frac{11400}{40}[/tex]
[tex]X_2 = 285[/tex]
None of X1 and X2 is greater than 300.
Hence, over 300 students did not support start time after 8:00am
None of X1 and X2 is greater than 300. so, over 300 students did not support start time after 8:00 am.
The population is 600 and the sample is 40.
What are Population Inferences?The population of inference refers to the population (or universe) to which the results from a sample survey are meant to generalize.
Over 300 students did not support start time after 8:00 am
For sample 1
[tex]\rm x_{1} =18\\[/tex]
The corresponding value of x1 in the overall population is:
[tex]\rm X_{1} =\frac{x_{1} }{n} \times N\\\rm X_{1} =\frac{18}{40} \times 600\\\rm X_{1} =\frac{10800}{40}\\ \rm X_{1} =270\\[/tex]
For sample 2
[tex]\rm x_{2} =19[/tex]
The corresponding value of x2 in the overall population is:
[tex]\rm X_{2} =\frac{x_{2} }{n} \times N\\\rm X_{2} =\frac{19}{40} \times 600\\\rm X_{2} =\frac{11400}{40}\\ \rm X_{2} =285\\[/tex]
None of X1 and X2 is greater than 300.
Hence, over 300 students did not support start time after 8:00 am.

15 points, solve a right triangle. Please simplify your answers as it says in the picture.
Given:
In triangle EFG, [tex]EF=10\sqrt{2}, m\angle G=90^\circ,m\angle E=60^\circ[/tex].
To find:
The measures of FG, EG and angle F.
Solution:
In triangle EFG,
[tex]m\angle E+m\angle F+m\angle G=180^\circ[/tex] [Angle sum property]
[tex]60^\circ+m\angle F+90^\circ=180^\circ[/tex]
[tex]m\angle F+150^\circ=180^\circ[/tex]
[tex]m\angle F=180^\circ-150^\circ[/tex]
[tex]m\angle F=30^\circ[/tex]
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin E=\dfrac{FG}{EF}[/tex]
[tex]\sin (60^\circ)=\dfrac{FG}{10\sqrt{2}}[/tex]
[tex]\dfrac{\sqrt{3}}{2}\times 10\sqrt{2}=FG[/tex]
[tex]5\sqrt{6}=FG[/tex]
Similarly,
[tex]\sin F=\dfrac{EG}{EF}[/tex]
[tex]\sin (30^\circ)=\dfrac{EG}{10\sqrt{2}}[/tex]
[tex]\dfrac{1}{2}\times 10\sqrt{2}=EG[/tex]
[tex]5\sqrt{2}=EG[/tex]
Therefore, the required measures are [tex]FG=5\sqrt{6}, EG=5\sqrt{2}, m\angle F=30^\circ[/tex].
