A vacant lot is in the shape of an isosceles triangle. It is between two streets that intersect at an 85.9degree angle. Each of the sides of the lot that face these streets is 150 ft. Long. Find the perimeter of the lot to the nearest foot.

Answers

1. An isosceles triangle has two equal sides and you have the length of these sides (a=105 feet), but you need the other one: "b". So, if you a draw a segment that bisects the angle of 85.9°,you will obtain two equal right triangles, as you can see in the figure attached. Now, you have to find the value of "x" and the side "b" will be 2x:

 Sin(α)=Opposite/Hypotenuse

 α=89.5°/2=42.95°
 Opposite=x
 Hypotenuse=105

 Sin(42.95°)=x/105
 x=(105)(Sin(42.95°))
 x=71.54 feet

 2. Then the other side of the isosceles triangle (b), is:

 b=2x
 b=2x71.54 feet
 b=143.08 feet

 3. The perimeter of the isosceles triangle, is:

 P=2a+b
 P=2(105 feet)+143.08 feet
 P=210 feet+143.08 feet
 P=353 feet

A particular computer takes 13 minutes to download a 39​-minute TV show. How long will it take the computer to download a 2​-hour ​movie?

Answers

Final answer:

It will take the computer 40 minutes to download a 2-hour movie based on its current download speed, which is 3 minutes of video per minute of download time.

Explanation:

To answer this question, we first need to establish the download speed of the computer. This can be done by dividing the length of the TV show by the time it takes to download it. In this case, the computer can download 39 minutes of video in 13 minutes, so its download speed is 39/13 = 3 minutes of video per minute of download time.

To find out how long it will take to download a 2-hour movie, we first need to convert the length of the movie to minutes, because our speed is in minutes of video per minute of download time. Two hours is equal to 2*60 = 120 minutes. Therefore to download a 120-minute video, it will take 120/3 = 40 minutes.

3.you have a mortgage payment of $1,248.90/month. Using proportions, what is the minimum amount you must have in realized income per month to keep your housing expense in the acceptable range?,

Answers

Final answer:

To determine the minimum amount of realized income per month to keep your housing expense in the acceptable range, set up a proportion using 30% of the mortgage payment and solve for x.

Explanation:

To determine the minimum amount of realized income per month to keep your housing expense in the acceptable range, we can use a proportion. Let's assume that the acceptable range for housing expense is 30% of your income.

First, we need to find the total monthly income that corresponds to 30% of the mortgage payment. We can set up a proportion:

x/1248.90 = 30/100

Cross-multiplying, we get:

100x = 30 * 1248.90

Simplifying, we find:

x = (30 * 1248.90)/100 = $374.67

Therefore, the minimum amount you must have in realized income per month to keep your housing expense in the acceptable range is $374.67.

If the product of two positive integers is 180 and the larger number is 5 times the smaller number, what are the numbers

Answers

Let the smaller number be x
The bigger number is 5x

5x(x) = 180
5x² = 180
x² = 180÷5
x²=36
x=√36
x = 6 

x=6
5x = 6 x 5
5x = 30

So the two numbers are 6 and 30

How do u do question 25. How do u find the measure of X?

Answers

recall that a circle has a total of 360°, now the arc that is NOT part of "x", is 250°, therefore the leftover, namely the arc made where "x" is at, has to be 360° - 250°, that's the degree measure of that arc.

now, arc's get their angle measure from the central angle they're in, in this case, "x" is the central angle, and therefore, it has the same measure of 360° - 250°.

A. Multiply both sides of the equation by 19.
B. Add 81 to each side of the equation.
C. Add 9 to each side of the equation.(MY ANSWER)
D. Multiply both sides of the equation by 13 .

Answers

Solve for x over the real numbers by completing the Square: None of the provided answers are correct.
3 x^2 + 18 x = 21

Subtract 21 from both sides:
3 x^2 + 18 x - 21 = 0

3 x^2 + 18 x - 21 = 3 (x^2 + 6 x - 7):
3 (x^2 + 6 x - 7) = 0

Divide both sides by 3:
x^2 + 6 x - 7 = 0

x = (-6 ± sqrt(6^2 - 4 (-7)))/2 = (-6 ± sqrt(36 + 28))/2 = (-6 ± sqrt(64))/2:
x = (-6 + sqrt(64))/2 or x = (-6 - sqrt(64))/2

sqrt(64) = sqrt(2^6) = 8 = 8:
x = (-6 + 8)/2 or x = (-6 - 8)/2

(-6 + 8)/2 = 2/2 = 1:
x = 1 or x = (-6 - 8)/2

(-6 - 8)/2 = -14/2 = -7:

Answer:  x = 1 or x = -7

To identify the opposite and adjacent of any angle is fairly simple

the adjacent is the part of the angle that connects with the hypotenuse to form the angle.   So in the 1st triangle the hypotenuse along with segment XZ forms angle Z.  That means that XZ is the adjacent.

To identify the opposite, you find the segment that connects the adjacent to the hypotenuse.

SO in the 1st triangle, segment XY connects the adjacent XZ with the hypotenuse.  So that means that XY is the opposite of angle Z.

. Classify the triangle according to side length and angle measurement.

(1 point)
isosceles; right
equilateral; obtuse
scalene; acute
scalene; right

Answers

Final answer:

The question requests the classification of a triangle by both its side length and angle measurement. An isosceles triangle has two equal sides, and if it also includes a right angle, it is classified as isosceles; right. This understanding combines the concepts of triangle classification by sides and angles.

Explanation:

The question asks to classify a triangle according to side length and angle measurement. When classifying triangles by side lengths, we have three categories: isosceles, scalene, and equilateral. An isosceles triangle has two sides of equal length, a scalene triangle has all sides of different lengths, and an equilateral triangle has all sides of equal length. In terms of angle measurements, triangles can be classified as right (one 90-degree angle), acute (all angles less than 90 degrees), or obtuse (one angle greater than 90 degrees).

According to the information provided and referencing the 4th Theorem, in an isosceles triangle, the angles opposite to the equal sides are equal. This property helps in classifying a triangle when given its angles or side lengths. Furthermore, for a triangle to be a right triangle, it must include a 90-degree angle. This is crucial when identifying a triangle as isosceles; right, which means it is an isosceles triangle with a right angle, typically resulting in the two equal sides being adjacent to the right angle.

4. An airplane at T(80,20) needs to fly to both U(20,60) and V(110,85). What is the shortest possible distance for the trip?
165units
170units
97units
169 units
is the answer A?

Answers

The distance formula for two points in a plane is 
D=sqrt( (x1-x2)^2 + (y1-y2)^2 ) 
 From T to U
 D= sqrt((80-20)^2 + (20-60)^2) = 72.11 
 Then flying from U to V
 D= sqrt((20-110)^2 + (60-85)^2) = 93.4 
 So T to U to V = 72.11+93.4 = 165.5 
 BUT checking also T to V to U
 From T to V
 D= sqrt((80-110)^2 + (20-85)^2) = 71.6
 Then from V to U
 D= sqrt((110-20)^2 + (85-60)^2) = 93.4 
 So from T to V to U = 165
 Pretty much the same both directions
 So yes the answer is A

I just took the test with that question it is that hopefully it helps 


A 565 cm 

Answer:

Ok the answer is 565 but I'm going to break it down for those who wanna know how

Step-by-step explanation:

So first let's just assume the jar is a cylinder which means to use the formula

[tex]V=\pi r^{2} h[/tex]

They saved you time of having to finf the Radius and such

firstly, we're gonna solve before she eats all that salsa lol

r = 6

h = 11

we're gonna substitute 3.14 for pi

of course you'll solve for it which you'll get

v = 1243.44

now you need to find the volume after she eats the salsa which the only difference is that the height will be 6 instead of 11

substitute

solve and you'll get

678.24

now that you have the volume of before and after she eats the salsa all you need to do is subtract to find the difference

1243.44 - 678.24

which you'll get

565!

Answers

Answer: The p(success) = 0.6

Your question is a little unclear, but I believe you are asking about the probability that at least one of the trials in the experiment were successful.

If that is the case, you simply have to add the probability of 1 success with the probability of 2 successes.

That is 0.48 +  0.16 = 0.64

Rounding our answer to one decimal place gives us 0.6.

The correct answer on the test was

P(success)=0.4

Solve for x in the equation x^2+10x+12=36.

A. x = –12 or x = 2
B. x = –11 or x = 1
C. x = –2 or x = 12
D. x = –1 or x = 11

Answers

Solve for x:
x^2 + 10 x + 12 = 36

36 = 36:
x^2 + 10 x + 12 = 36

Subtract 12 from both sides:
x^2 + 10 x = 24

Add 25 to both sides:
x^2 + 10 x + 25 = 49

Write the left hand side as a square:
(x + 5)^2 = 49

Take the square root of both sides:
x + 5 = 7 or x + 5 = -7

Subtract 5 from both sides:
x = 2 or x + 5 = -7

Subtract 5 from both sides:
Answer:  x = 2 or x = -12 Thus the Answer is A.
Final answer:

To solve the equation x^2+10x+12=36, subtract 36 from both sides and factor or use the quadratic formula to find the solutions. The solutions are x = -12 or x = 2.

Explanation:

To solve the equation x^2+10x+12=36, we need to bring all terms to one side of the equation and then factor or use the quadratic formula. Subtracting 36 from both sides gives us the equation x^2+10x-24=0. We can then factor this equation as (x+12)(x-2)=0. Setting each factor equal to zero, we find that x = -12 or x = 2.
