C is the hypotenuse (or AB if they write it that way). The hypotenuse is the longest side and is always across from the right angle in a right triangle.
9 + 9n = 9
*subtract 9 from both sides
9n = 0
*divide both sides by 9
n = 0/9 = 0
n = 0
Answer:
45 square centimeters
Step-by-step explanation:
to find the area of the rectangel multiply its height, which is 5 by its length which is 9.
9 x 5 = 45
Answer:
The second term in the sequence is -9
Step-by-step explanation:
Given the nth term of a sequence to be a(n) = a(n-1)+4 where n is the number of terms of the sequence
If a(1) = -13... (1)
The second term of the sequence is generated for n= 2:
a(2) = a(2-1)+4
a(2) = a(1)+4... (2)
Substituting equation 1 into 2
a(2) = -13+4
a(2) = -9
The second term in the sequence is -8
Find the difference in gallons and the difference in the weights
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons
