Toms house cost $100000 in the year 2000 in 2008 he sold his house for 125000 what was the percentage of change in the price of
Leno4ka [110]
There was a 125% change in the price of the house.

The changed price was an increase of from the original 100,000 therefore the answer can be concluded to be above 100%.

Anyways, to solve this problem you need to find what 125,000 is OF 100,000, meaning you need to divide. 125,000/100,000=1.25. 1.25 can then be changed into 125%.

The ratios of the measures of the angles in triangle XYYZ is 7:13:16. Find the measures of the angles
kirza4 [7]

Answer:

let the angles be 7x , 13x , 16x

7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)

36x = 180

x = 180 / 36

x = 5

therefore the angles are:

7 X 5 = 35 degree

13 X 5 =  65 degree

16 x 5 =  80 degree

From the top of a building, the angle of elevation to the top of a nearby building is 28° and the angle of depressions to the bo
kicyunya [14]

Answer:

Step-by-step explanation:

The idea here is to find the value for x and y, then add them together. See the pic I attached below. We will solve for side x first.

Side s is across from the reference angle of 48 degrees; side measuring 50 m is adjacent to the reference angle 48 degrees. Therefore, we will use the tangent ratio to solve for x:

tan48=\frac{x}{50} and

50tan(48) = x so

x = 55.53m

Now we will do the same and solve for y. This time the reference angle is 28 degrees. Side y is opposite the reference angle and the side measuring 50 is adjacent to the reference angle, so we will use the tangent ratio again:

tan28=\frac{y}{50} and

50tan(28) = y so

y = 26.59. Therefore,

x + y = 55.53 + 26.59 and

the height of the taller building is

82.1 m

PLEASE HELP!!!!!! I HAVE BEEN STUCK FOR DAYS!!!!
Sveta_85 [38]

Answer:

40 terms

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

S_{n} = \frac{n}{2} (a₁ + a_{n} )

then

\frac{n}{2} (- 4 - 82) = - 1720 ( multiply both sides by 2 to clear the fraction )

- 86n = - 3440 ( divide both sides by - 86 )

n = 40

the series has 40 terms
