Answer:
1 1/3
Step-by-step explanation:
2/5 x 10/3
<em>Multiply across - </em>
10 x 2 = 20
5 x 3 = 15
20/15
<em>Simplify - </em>
20/15 to 4/3
Divide 4 by 3
You get 1 1/3
Cross multiply and you get
50t = 40 x 16
50t = 640
t = 640/50
t = 12.8
The answer:
first of all, we should know that the expression of a vector V (a, b) can be written as follow:
V = r (Vx i + Vyj), where r is the length of the vector, it is r = sqrt(V²x + V²y)
Vx is the component lying on the x-axis and Vy on the y-axis
<span>v ⃗ lies in Quadrant II, means Vx is less than 0 (negative)
</span>
so Vx= -r sin30° and Vy= rcos30°
r= <span>‖v ⃗ ‖=4√3
</span>
so we have v = - 4√3sin30° i + 4√3 cos30° j
the components are
v(- 4√3sin30°, 4√3 cos30°) = (-2√3, 4√3 cos30°)
You have to multiply 18 by three which is 54 inches.
then you have to divide 54 by 12 because a foot is 12 inches.
when you do that you should get 4.5
then you subtract 4.5 by 5.5 and get 1 foot of rope left
18*3=54
54/12=4.5
5.5-4.5=1.0
1 foot of rope
Answer:
55, 121
Step-by-step explanation:
2*2 =4
22*2=44
but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55
thats the first box.
The second box is 55*2+11 which is 121
55:is the first box
121 is the second empty box
