The answer is 12
(note: someone helped me find the answer)
Answer:
Around 1 hour
Explanation:
Ok so we know 15=24 min
and then we know he needs to grade 36 assignments so we can do 15 2x because 15+15=30 then we would have 6 assignments left over but we can do what we already have which is 48 cause 15=24 min so then we do 24+24 cause it’s 15 2x and then we get 48 min with 30 assignments done then we move on to 6 assignments which we have no minutes for so we need to find it so we can do;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
And
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
And then count by 2 min and cross out 1 assignments each time and then would be 1=2 min 2= 4 min 3=6 min 4= 8 min 5= 10 and 6= 12 min so 6 assignments would be 12 min for 6 assignments so then we do 24-12 and we get 12 so then we do 48+12= 60 and 60 min= an 1 hr so he takes about 1 he to grade the assignments
But then again.... I could be wrong so sry in advance
Answer:
13- No because the size of the triangle can be different, meaning bigger side length
in 14 he is forgetting the lines at the angles. The little circular ones that say the angles are congruent.

Answer:
14 miles.
Step-by-step explanation:
Let the distance traveled from home to destination = x miles.
Speed while going to friend's house = 35 miles per hour.
Speed while coming back = 40 miles per hour.
Total Time taken for the journey = 45 minutes = 0.75 hours.
Let the time taken while going to friend's house = y hours.
Therefore, the time taken while going to friend's house = (0.75 - y) hours.
To find x and y, model the speeds of both the journeys.
Speed while going to friend's house = Distance/Time.
35 = x/y.
x = 35y (Equation 1).
Speed while coming back = Distance/Time.
40 = x/(0.75 - y).
x = 40(0.75 - y) (Equation 2).
Since x = x, therefore:
35y = 30 - 40y.
75y = 30.
y = 30/75.
y = 0.4 hours.
Put y = 0.4 hours in Equation 1:
x = 35y.
x = 35(0.4).
x = 14.
Therefore, the distance between my friend's house and my house is 14 miles!!!
