Answer:
16.8 cm
Step-by-step explanation:
Volume = length x width x height
V = 4 x 3 x 1.4
V = 16.8
Answer: A rhombus
Step-by-step explanation:
Let's solve for x.
−b3+3b2+8−(x−5b2−9)=5b3+8b2+17
Step 1: Add b^3 to both sides.
−b3+8b2−x+17+b3=5b3+8b2+17+b3
8b2−x+17=6b3+8b2+17
Step 2: Add -8b^2 to both sides.
8b2−x+17+−8b2=6b3+8b2+17+−8b2
−x+17=6b3+17
Step 3: Add -17 to both sides.
−x+17+−17=6b3+17+−17
−x=6b3
Step 4: Divide both sides by -1.
−x
−1
=
6b3
−1
x=−6b3
Answer:
x=−6b3
Answer:
6.7 seconds
Step-by-step explanation:
Let's calculate the maximum height covered by the object
Max height= U²Sin²tita/2g
Where g is acceleration due to gravity
Max height= 40²(sin90)²/(2*9.81)
Max height= 1600/19.62
Max height=81.55 m
Total max height= 30+81.55
Total max height= 111.55 m
Time t it will take to travel from the max height at acceleration of 4.9 m/s²
S= ut + ½at²
u= 0 at Mac height
S= 111.5 m
111.5 = ½(4.9)t²
223/4.9= t²
45.5= t²
6.745 seconds= t
6.7 seconds= t
$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher
From the total $79 we substract the $29 she paid with cash or card.
79-29=50
So the value of the voucher is $50
