Answer:
the length of the unknown leg is 10 cm
Step-by-step explanation:
Use the Pythagorean theorem to solve the problem. The theorem states that the square of the hypotenuse equals the addition of the squares of the two legs:
since we know the length one of the legs (24 cm) and also of the hypotenuse (26 cm), we can solve for the unknown leg in the equation above:
Therefore, the length of the unknown leg is 10 cm.
Nit 100% sure.
I think rate of change is 334ft
r=distance/time
time: 5:30-2:00=3.5
distance: 3560-2390=1170 ft
r=1170/3.5
r=334 ft

Answer:
There are 25 males and 21 females in the class
Step-by-step explanation:
Let us use the equation to solve the question
∵ A Spanish class has a total of 46 students
∵ The number of males is 4 more than the number of females
→ Assume that the number of females is x
∵ The number of females = x
∴ The number of males = x + 4
→ Add the numbers of males and females and equate the sum by 46
∴ x + x + 4 = 46
→ Add the like terms in the left side
∴ 2x + 4 = 46
→ Subtract 4 from both sides
∴ 2x + 4 - 4 = 46 - 4
∴ 2x = 42
→ Divide both sides by 2
∴
∴ x = 21
∵ x represents the number of females
∴ There are 21 females
∵ x + 4 represents the number of males
∴ The number of males = 21 + 4 = 25
∴ There are 25 males
