Answer: 145 cans
Step-by-step explanation:
arithmetic sequence
aₙ = a₁ + (n-1).r
aₙ → last term
a₁ → 1st term
n → quantity of terms
r → common difference
a₁ = 1 (one can at the top)
aₙ₋₁ = 25
aₙ = 28
To find out How many cans are in the entire display, we need the SUM of the arithmetic sequence: S = (a₁+aₙ)n/2
∴
S = (1+28).n/2
n = ?
aₙ = a₁ + (n - 1).r
r = 28 - 25 = 3
28 = 1 + (n - 1).3
27 = (n - 1).3
27/3 = (n - 1)
9 = n - 1
n = 9 + 1 = 10
S = (1+28).n/2
S = (1+28).10/2 = 29.10/2 = 29.5 = 145
The answer would be 1/3. You have to work backwarda for this problem. You start off by subtracting 5/4 - 3/4 =2/4 which simplifies to 1/2. Then, you have to add 1/6. Using the greatest common denominator, you have 3/6 + 1/6=4/6 which simplifies to 2/3.
To find the volume of a prism, the formula is V = B*h
Volume = Base*Height
Answer:
286 mm²
Step-by-step explanation:
A trapezium is given with ,
- Parallel sides = 24mm , 28 mm
- Height = 11mm .
<u>The </u><u>area </u><u>is </u><u>given</u><u> by</u><u> </u><u>:</u><u>-</u><u> </u>
Area = 1/2 ( b₁ + b ₂) × h
Area = 1/2 ( 24 + 28)×11 mm²
Area = 1/2 × 52× 11mm²
Area = 286 mm²
<h3>
<u>Hence </u><u>the</u><u> </u><u>area </u><u>of</u><u> the</u><u> </u><u>trapezium</u><u> </u><u>is </u><u>2</u><u>8</u><u>6</u><u> </u><u>mm²</u><u>.</u></h3>
Answer:
16,088 more miles
Step-by-step explanation:
Do 26,481-10,393 to get the answer.
26,481-10,393=16,088
The reason that you need to use subtraction to solve this problem is because the word problem says ”how many more”. I’ve learned in school that this is a sign that you have to find the difference to the terms being used in the problem, in this case, 26,481 and 10,393. To find the difference is to subtract the smaller number from the larger number, showing that you have to do 26,481-10,393 to get the answer.
