Hello. Firstly you have to remembet that the sum of the three angles in any triangle is 180grades
So, determining the constant (k) you will have:
2:9:1
2k+9k+1k=180
12k=180 180/12=k
k = 15
Multiply the constant by 180 and divide by the given ratio:
180*15 / 2
180*15 / 9 etc
then your angles are
2:9:1
24:108:12

Answer: 8 movies

12 + 1.50x = 3x

Move the variables to one side

12 = 1.50x

Isolate x

8 = x

Check:

3(8)= 24

12.00 + 1.50(8) = 24

On a map, the distance between Greenville and Fairview is 7 1/4 inches. If the map uses a scale of 1/2 inch = 40 miles, what is

lubasha [3.4K]

The actual distance between cities is 580 miles.

Step-by-step explanation:

Map distance = $7\frac{1}{4}$ inches = $\frac{29}{4}\ inches$

Scale used;

$\frac{1}{2}\ inches = 40\ miles$

Multiplying both sides by 2

$2*\frac{1}{2}=40*2\\1\ inch = 80\ miles\\$

Now,

$\frac{29}{4}\ inches = \frac{29}{4}*80\\\\\frac{29}{4}=29*20\\\\\frac{29}{4}\ inches = 580\ miles$

The actual distance between cities is 580 miles.

Find the compound interest compounded annually on rupees 2700 rate 6 ⅔% per annum and time is 2 years

<u>Answer:</u>

plz mark me as brainliest ...TOOK ME LONG TIME TO TYPE

answer = CI = 3108 RUPEES

<u>Step-by-step explanation:</u>

i am doing the method in which u find the simple interest of first year then second year.

SI FOR 1ST YEAR= P X R X T / 100

SI = 2700 X 20 X 2 / 3 X 100 ( RATE OF INTEREST IS 20 / 3)

SI = 108000/300

SI = 360

SI FOR SECOND YEAR =

P = 2700 + 360= 3060

SI = 3060 X 20 X 2 / 300

SI= 122400 / 300

SI = 408

COMPOUND INTEREST (CI) = PRINCIPLE + SI OF 2ND YEAR

CI = 2700 + 408

CI = 3108 RUPEES

or u can solve be the method

CI = amount - principle

Amount= principle x (change in ratio) raised to time
