Use photo math the app will help with you :))
Step-by-step explanation:
m<ACB=m<CBD=90 degrees (given) and AB=DC (given)
BC=BC (reflexive property)
m<ABC=m<BCD (alternate interior angles)
triangle ABC is equivalent to triangle DCB by Angle Side Angle.
I think that's correct, I'm on this unit too.
The first thing we must do for this case is to rewrite the expression of the volume correctly.
We have then:
v = 0.95 * h ^ 2.9
Substituting the value of h we have:
v = 0.95 * (7.5) ^ 2.9
v = 327.6432831
round to the nearest tenth:
v = 327.6 feet ^ 3
Answer:
the amount of water in the container when h = 7.5 feet is:
v = 327.6 feet ^ 3
Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
Answer:
it would be C
Step-by-step explanation:
A trapiziod equals 360 degrees in total, so 110+110+70 is 290.
the total degrees 360-290 would give you 70 degrees, so C is correct.
