Answer:
1 min 45 sec
Step-by-step explanation:
First convert 14 min to seconds.
14 x 60 = 840s
Now we can use ratios to find the answer
840s : 800m
Divide both sides by 8
105s : 100m
105s is 1 minute and 45 seconds
Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.
Step-by-step explanation:
A relationship is said to have direct variation if ratio of second variable to the ratio of first variable remains constant.
A relationship is direct variation if 
where k is the constant.
Now checking if the given data is having direct variation or not.
x y
3 24
4 32
5 40
6 48
Now finding y/x
if y=24 and x = 3 then y/x = 24/3 = 8
if y=32 and x = 4 then y/x =32/4=8
if y=40 and x = 5 then y/x =40/5 =8
if y=48 and x = 6 then y/x =48/6= 8
Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.

Answer:
im saying d is the answer
Step-by-step explanation:
Answer:
∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.
Step-by-step explanation:
From the picture attached,
p and q are the parallel lines and w is a transversal.
∠1 ≅ ∠3 [Vertically opposite angles]
∠1 ≅ ∠5 [Corresponding angles]
∠1 ≅ ∠7 [Alternate exterior angles]
Therefore, ∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.
Answer:
Base of the original triangle is 12 cm.
Step-by-step explanation:
Let base of triangle be x
two equal legs of triangles by y
therefore perimeter of triangle
x+y+y = 50 or x+2y =50
according to the question
if base is x+3 and leg is y-4
then both are equal
that is x+3 = y-4
y-x = 7 or y =x+7
x+2y =50
x+2(x+7) = 50
x+2x +14 =50
3x +14 =50
3x = 50 -14
3x = 36
x = 12
therefore base of the original triangle is 12 cm
