Angles along a straight line equal 180. This means that the unmarked angle of the triangle is equal to (180-153)=27.
Angles in a triangle add to 180. This means:
(x-4)+(2x+10)+27=180
3x+33=180
3x=147
x=49
Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000
Answer:
y=log_(6)x
Step-by-step explanation:
From the definition of logarithm:
<---> 
In our case, we have
which means that b=6, therefore the inverse function is
which can be rewritten by switching x and y:
Answer:
10.5
Step-by-step explanation:
Area is length times width so, 3.5 times 3 equals 10.5. 10.5 is the area of the given figure.
