Answer:
The shape is a square and a triangle, so all sides of the square are equal to 6, and applying the Pythagorean law to a right-angled triangle, we can find the value of x
Then
Answer:
one is direct x = 0 , next we need to find out 18x^2 - 51x + 36. ( Shri Dharacharya formula)
Step-by-step explanation:
1. ( - (-51) + - √ ( 51^2 - 4* 18 *36)) / 2* 18
2. ( 51 + - 3 ) / 36
3. x = 0 , x = 3/2 , x = 4/3
Is it a multiple choice question or do you have to give your own answer
Answer:
630
Step-by-step explanation:
The sum of an arithmetic sequence is given by ...
Sn = n(2a1 +(n-1)d)/2
For the sequence of numbers of bales, we have ...
a1 = 123, d = -11, n = 7
so the total number of bales in 7 trips around the field is ...
S7 = 7(2·123 +6(-11))/2 = 630
The total number of bales made is about 630.
_____
123 + 112 + 101 + 90 + 79 + 68 + 57 = 630
