Volume = Area of triangle x length
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 4
Area of triangle = 10
Volume = area of triangle x length
Volume = 10 x 12
Volume = 120 cm^3

3) 3
Step-by-step explanation:
Im not sure how to explain this but i hope this helps!
Step-by-step explanation:
ABC is an isoceles triangle (both legs are equally long). and AB is its baseline.
OC is now a median for ABC splitting the angle at C and AB in half.
so, we have 2 right-angled triangles : OAC and OBC.
the half-angles at C are 42/2 = 21°.
the angles at A and B are 90°.
and the half-angles at O are 180 - 90 - 21 = 69°.
remember that the sum of all angles in a triangle must always be 180°.
AB are the heights of both of these triangles.
the single height is sin(69)×7 = 6.535062985... cm
and so,
AB = 2× height = 13.07012597... cm.
B 8:00 am
8:00+1:25=9:25
9:25+25=9:50
9:50+30=10:20
B $240
60×2=120×2=240
Answer:
$6.8
Step-by-step explanation:
suppose Molly's account balance = X
25 + 2.2 = X * 4
27.2 = X*4
27.2/4 = X = 6.8
