Last quarter, 84 seventh grade students made honor roll. If there are 400 students in the seventh grade, what percent made honor roll?

21%

Step-by-step explanation:

Formula for this type of problem is

cross multiply

divide by 400

/400   /400

plug 21 into the original equation

simplify

.21 can be represented as 21%

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
