The length of a shadow building is 28 m the distance from the top of the building to the tip of the shadow is 38 m find the height of the building if neccessary round your answer nearest tenth
Answer:
25.7m
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2
28^2+b^2=38^2
784+b^2=1444
b^2=660
b=25.6904652 or 25.7m
(x+1)^2 = -4
What are the solutions?
Answer:
x = 4i - 1 or
x = 4i + 1
Step-by-step explanation:
(x+1)^2 = -4
x+1 = (+-)4i
x = +-4i - 1
==>
x = 4i - 1 or
x = 4i + 1
Mary was writing a test. On the test there was a question which was "What is the square root of 30?" How can you estimate the square root of 30?
After she was done the test. she got it back from the teacher and the mark she got was 26/30. Find the percentage of her mark.
Answer:
86.6%
Step-by-step explanation:
1. Divide the amount of points Mary got from the test by maximum amount of points
26/30≈0.866
2.Multiply that by hundred
0.866*100=86.6
Answer: 86.6%

Total number of people who play sports in the Algebra 2 class:
[tex]21 - 9 = 12[/tex]
If there are 10 students who play Basketball, there are 2 students who ONLY play Baseball. If there are 9 students who play Baseball, there are 3 students who ONLY play Basketball.
So the number of students who play BOTH sports is:
[tex]12 - 2 - 3 = 12 - 5 = 7[/tex]
If 7 from the 21 Algebra 2 class students play BOTH sports, the probability is:
[tex]P = \frac{7}{21} = \frac{1}{3}[/tex]
how do i make my grades go up quickly- yes in all subjects plz help me
Answer:
Step-by-step explanation:
A way to make your grades go higher is by asking your teacher for extra credits. If you fail some quizzes ask your teacher to re-take it to get a better grade, another way is ask your teacher for assistance on assignments.
Here are two stories: The initial freshman class at a college is 10% smaller than last year’s class. But then during the first week of classes, 20 more students enroll. There are then 830 students in the freshman class.
A store reduces the price of a computer by $20. Then during a 10% off sale, a customer pays $830
here are two equations: 0.9x+20=830, 0.9(x-20)=830
A. Decide which equation represents each story.
B. Explain why one equation has parentheses and the other doesn't.
C.Solve each equation, and explain what was the solution means in the situation.
Thank you to the people that answered my questions!
Using proportions, it is found that:
a. The equations are related to the stories as follows:
0.9x+20=830 = Class in college.0.9(x-20)=830 = Computer price.b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.
c. The solutions are given as follows:
x = 900: Size of the freshmen class in the previous year.x = 942: Original price of the computer.What is a proportion?A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.
One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.
For the college class, we have that:
It is 10% smaller than last year's amount of x, that is, 90% of x = 0.9x.Then 20 is added to this amount, that is, 0.9x + 20.The equivalent amount is of 830 students, hence the equation is:
0.9x + 20 = 830
The solution is found as follows:
0.9x = 810
x = 810/0.9
x = 900.
Which is the size of the freshmen class in the previous year.
For the computer in the store, we have that:
The price of x was reduced by $20, hence x - 20.Over the price reduced by $20, a reduction of 10% was applied, hence the price paid is of: 0.9(x - 20).This price is of 830, hence the equation is:
0.9(x - 20) = 830
The solution, which is the initial price of the computer, is found as follows:
x - 20 = 830/0.9
x = 20 + 922
x = 942.

Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer:
Step-by-step explanation:
(x+78)+(x-12)+x=180
3x+66=180
3x=114
x=38
P=26

Answer:the correct answer is C
Step-by-step explanation:
Tell whether the statement is always, sometimes, or never true. Explain.
1. If x and y are supplementary angles, then y is acute.
2. If x and y are complementary angles, then x is obtuse.
Answer:
1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.
2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.
Step-by-step explanation:
Answer:
1) Sometimes
2) Never
Step-by-step explanation:
1) you could have two angles add up to 180 degrees and one of them could be less than 90
example, x = 140° and y = 40°
2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Area = 115 yards
Step-by-step explanation:
If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.
Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters. How tall is the hotel on Squidward’s drawing?
Answer:
10 m building in Patrick's drawing would be of 0.5 cm
Step-by-step explanation:
Scale of Patrick's drawing is
1 inch = 10 meters
or 2.54 cm = 10 meters
1 cm = 3.94 m
In case of Squidward the scale is 2 cm = 40 meters or
1 cm = 20 meters
So a 10 m building in Patrick's drawing would be of
0.5 cm
Answer:
13.5

C. Residuals aren't random; linear is not a good fit
Step-by-step explanation:
The attached graph shows the given points (black) and the best-fit line (red). The residuals are connected by the dashed red line. They are decidedly NOT random. It appears that an exponential fit would work better than this linear fit.
The residual values are not randomly dispersed around the horizontal axis, so a linear fit is not appropriate.
what is the slope line perpendicular to the equation 4x+3y=9
Answer:
m=3/4
Step-by-step explanation:
first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)
we have the equation 4x+3y=9
subtract 4x from both sides
3y=-4x+9
divide by 3
y=-4/3x+3
perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1
so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1
(m is the slope value)
-4/3m=-1
multiply by -3/4
m=3/4
therefore the slope of the perpendicular line is 3/4
