a=360t
b=280t+(280*.25)
360t=280t+(280*.25)

Answer:
40 inch
Step-by-step explanation:
1 inch=2.54cm
so 40 inch= 101.6 cm
There are 4 quarts in 1 gallon, so a rate of 120 gallons per minute converts to 4 x 120 = 480 quarts per minute. To find the per hour rate, we simply multiply our per minute rate by 60, obtaining 480 x 60 = 28800 quarts per hour.
Answer:
5 days
Step-by-step explanation:
(3 1/3 miles)/(2/3 miles/day) = (10/3)/(2/3) days = 10/2 days = 5 days
_____
time = distance / speed
Based on the percentage that passed English and those who passed Mathematics and those who failed and passed both, the total number of students who appeared in the examination are 60 students.
The number of students who passed only in Math are 12 students.
<h3>What number of students sat in the exam?</h3>
This can be found as:
= Total who passed English only + Total who passed Math only + Total who failed both + Total who passed both
Assuming the total is n, the equation becomes:
n = 0.75n - 21 + 0.55n - 21 + 21 + 0.05n
n = 1.35n - 21
21 = 0.35n
n = 21 / 0.35
= 60 students
The number who passed mathematics only is:
= (60 x 55%) - students who passed both
= 33 - 21
= 12 students
