Answer:
sin 70 degrees = 0.9396, 0.9396*3 approximately equal to the 2.82cm one area is 6*2.82/2=8.46cm²
Step-by-step explanation:
- Known this square covers an area of 36 cm square, so its length is 6 cm.
- so, we know that the lower side of the triangle is six, half of it is 3 cm.
- We make a triangle, and then the Angle of the triangle is 70 degrees, so, we can use the sin is to use bottom neighborhood is sin70 degrees = hemline is present in addition to 3cm.
12 is first one 7 is 2nd one 9 is the last one
True because decimals do have the same number when they are equivalent
To make the equation easier so that you don't have to use fractions.
Answer:
33.33%
Step-by-step explanation:
We need to calculate the <u>unit selling price and cost of each cosmetics.</u>
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%
