Answer:
Here ,
2x-30° +70° +x-10° = 180° ( sum of triangle is 180°)
3x+30 =180°
3x=150°
x=50°
Answer:
0.3
Step-by-step explanation:
Percent means 'per 100'. So, 30% means 30 per 100 or simply 30/100. If you divide 30 by 100, you get 0.3 (a decimal number). So, to convert from percent to decimal, simply divide by 100 and remove the '%' sign. There is a easy way to convert from percent to decimal: Just move the decimal point 2 places to the left.
Hope this helps :)
pls give brainliest :p
And let me know what you think of my pfp :0
The answer to this equation will be 2.
Answer:
so make an equation. You now that RS=6n and RS=42. ST is the total sum of all points so the equation would be 6(42)=35. 6X42= 252. Divide 252 by 35 and your answer should be A: 7
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using cross- products, that is
=
then ad = bc
Given the ratios
and 
Then equating and using cross- products
If both sides equate then the ratios are equivalent
=
, then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent
