Answer:
1089
Step-by-step explanation:
The original number is A0CD, We have that DC0A = 9 x A0CD.
If A =1, then D = 9 and we have:
9C01 = 9 x 10C9
In order for this expression to be true, the following must also be true:
(C x 9) + 8 must be divisible by 10, which means that C x 9 must end in a 2.
The only multiple of 9 (from 9 to 81) that ends in a 2 is 72.
72 = 9 x 8.
Therefore, C must be 8 and the original number is 1089. Multiply it by 9 to check the answer:
1089 x 9 = 9,081
Therefore, 1089 is correct.
Here y=1/2 x=pi/3=60°
y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS
so that point is on curve y=cosx
X(a+b)-y(a+b)
*factor out (a+b)*
=(a+b)(x-y)
Answer:
30
Step-by-step explanation:
20+12-E=2
32-E=2
-E=-30
E=30
Answer:
190 baskets of strawberries
Step-by-step explanation:
The question is incomplete as it didn't state what we are to determine from the information given.
Let's determine total amount picked in the three days.
1st day picked 90strawberries
Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day
= (2/3)(90)
Amount of strawberries on 2nd day = 60 baskets of strawberries
Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day
= (2/3) (60)
Amount of strawberries picked on 3rd day = 40 basket of strawberries
Total amount picked for 3 days = 90+60+40
= 190 baskets of strawberries
