<h3> Number = 23</h3>
<h2>Step-by-step explanation:</h2>
<h3>Given:</h3>
Six is subtracted from a number.
The result is equal to one fourth of the sum of the number and 45 find the number .
<h3 /><h3>To Find:</h3>
What is the number ?
Solution: Let the number be x.
➟ Subtracting 6 from x.
➟ (x – 6) ㅤㅤㅤㅤㅤ(eqⁿ 1)
Now,
➙ One fourth of sum of the number + 45
➙ 1/4 × x + 45
➙ x + 45/4ㅤㅤㅤㅤ(eqⁿ 2)
According to the question,
Equation 1 = 2
⟹ (x – 6) = x + 45/4
⟹ 4(x – 6) = x + 45
⟹ 4x – 24 = x + 45
⟹ 4x – x = 45 + 24
⟹ 3x = 69
⟹ x = 69/3
⟹ x =23
Hence, the number is 23.
Answer:
The correct answer is d. oviduct (uterine tube)
Explanation:
Oviduct is a funnel shaped narrow duct that helps in transportation of oocyte towards the uterus. Oviduct is also called uterine tube or fallopian tube and is about 4-5 inches long. It is made up of three segments infundibulum, ampulla and isthmus.
Infundibulum has a finger like projection over the ovaries and receives the egg released from the ovary. Ampulla consists the major part of oviduct and provide perfect condition for fertilization of ovum and transfers the egg towards isthmus.
The final segment of oviduct is isthmus which connects ampulla to uterus and transport the oocyte towards the uterus for further development.
