Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
Answer:
4 x 100 = 400
400 ÷100 = 4
B= 100
Step-by-step explanation:
The closer Diana gets to the building, the smaller the angle becomes
Diana is 17.6 feet closer to the building
<h3>How to calculate the distance from the building</h3>
To calculate the distance between her and the building, we make use of the following tangent ratio
Where:
- h represents the height of the building; h = 130
- d represents the distance from the building
So, we have:
Make d the subject
Evaluate tan(40)
Initially, Diana is at a distance of 172.53.
The difference in both distance is:
Hence, Diana is 17.6 feet closer to the building

Answer:
A, C, E for the first one; B, C, E for the second one; B and E for the last one
Step-by-step explanation:
The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The sum of capacity minus three and one-third times n plus one-sixth ended capacity + capacity one and three-sixths times n minus three-twelfths end quantity.
Let n be the number. Then the expression will be
⇒ -(3 1/3)n + 1/6 + (1 3/6)n - 3/12
Simplify the equation, then we have
⇒ -(3 1/3)n + 1/6 + (1 3/6)n - 3/12
⇒ -10/3 n + 3/2 n + 1/6 - 1/4
⇒ -11/6 n - 1/12
The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.
