Answer:
1/3
Step-by-step explanation:
Y/x=k that is the equation for constant of proportionality
2/6=k
1/3=k
Answer:
440cm³
.45
1.49538 ft
43.6
Step-by-step explanation:
1.
Start by finding the area of the base
.5*(a+b)*h
.5*(8+14)*4= 44
Then just multiply this by distance between the ends
44*10=440
2.)
To get from 2.7 to 9 we muiltply by 9/2.7= 3.33333333
which means that
3.333333333x=1.5
x=.45
3.)
Height:shadow
6.5:1.8
5.4:x
To get from 6.5 to 5.4 we multiply it by (5.4/6.5) or .8307
which means to get from 1.8 to x we muiltply 1.8*.8307= 1.49538
4.)
Same kind of deal as the last one
to get from 13 to 27 we mulitply by (27/13) or 2.076923 which means to get from 21 to x we multuply 21*2.076923=43.6
(x,y)-->(-x,-y)
The new coordinates would be (1,-7)
Answer:
3 1/2
Step-by-step explanation:
-4 1/4 -(-7)= 2 3/4
2 3/4 -(-3/4)= 2 3/4 + 3/4
3 1/2
