Answer:
180 minutes
Step-by-step explanation:
Starting with the distance formula ...
d = rt
dividing by the coefficient of t will give an equation for t:
t = d/r
Ryan's rate of 4 miles per hour can be expressed in minutes as 4 miles per 60 minutes. The Ryan's time is ...
t = (12 mi)/(4 mi/60 min) = 12·60/4 min = 180 min
Ryan's time is 180 minutes.

Answer:
2,600 students attend the school.
Step-by-step explanation:
We know that 24% of the total students are in twelfth grade, and 624 are in twelfth grade. This means 624 is 24% of the total. We can see that 100 / 24 = 4.167, and if we multiply 624 by 4.167, we get the total students attending the school, 2,600.
Answer: I think that would be 5x3
Step-by-step explanation:
Formula to find the area of a triangle = × base × height
For triangles A, B and D, the base occupies 4 squares and the height occupies 4 squares.
Therefore, area = × 4 × 4
= 2 × 4 = 8 sq. units
For triangle E, base occupies 2 squares and height occupies 8 squares.
Therefore, area = × 2 × 8
= 8 sq. units
For triangle C, base occupies 3 squares and height occupies 5 squares.
Therefore, area = × 3 × 5
= 7.5 sq. units
Hence, triangles whose area is 8 sq. units are A, B, D and E.
