It should be 7,620 since 10x10x10 is 1,000 and you multiply that by 7.62 and it equals 7,620
Direct variation is y=kx where k is a constant
the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation
the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so
see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it
2nd is increase and y decrease, so not direct variation
3rd is x is same but y increase so nope
4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k
-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true
answer is last option
The second midpoint is (-15,8)
Answer:
no
Step-by-step explanation:
7x0 is 0 because anything times 0 is 0 I think and 7+0 is 7 because you are adding nothing to 7
Answer:
5/4 ft
Step-by-step explanation:
Given data
Area= 5/12 square feet
Height= 1/2 ft
Base=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
5/12= 1/2* B* 1/2
5/12= B/4
cross multiply
12B= 20
B= 20/12
B= 5/3
Hence the base is 5/4 ft
