Answer:
B. 4200
Step-by-step explanation:
A suitable calculator can add the terms for you. (See attached)
__
The first term is 69, and the common difference is 75-69 = 6. The general term is ...
an = a1 +d(n -1)
an = 69 +6(n -1)
Then the 28th term is ...
a28 = 69 +6(27) = 231
The average term is (a28 +a1)/2 = (231 +69)/2 = 150.
The sum is the number of terms multiplied by the average term:
sum = 28×150= 4200
Answer:
Part A: A
Part B: A
Step-by-step explanation:
1)
the inequality should be less than or equal to, since we need to find how many are left
now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few
thus, the answer is A
2)
A again is correct, since it represents:c ≤ 56
B represents c ≥ 56
C represents c ≤ –56
D represents c ≥ -56
Answer:
sin(R)=6/sqrt(97)
Step-by-step explanation:
Sine is opposite/hypotenuse
If you want to know what the angle is, Angle R= about 37.5
Hope this helps
A pair of fractions that use a least common denominator and that are equivalent to 9/10 and 5/6 are 27/30 (equivalent to 9/10) and 25/30 (equivalent to 5/6). Hope it helps :)
