A jogger ran 7 miles, decreased her speed by 1 mile per hour, and then ran another 8 miles. If her total jogging time was 3 2/5 hours, find her speed for each part of her run.

the answer is b i just did that

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
