Answer:
Step-by-step explanation:
Not sure what the question is here.
L = W-8
Perimeter = 2L + 2W = 44
L+W = 22
(W-8)+ W = 22
W = 15 ft
L = 7 ft
Since there are 8 boats (2 yachts + 6 barges) the three partial products would be as follows:
100 * 8
20 * 8
6 * 8
These are from taking the gallons of fuel for each boat that are needed and breaking it into the place values.
(100*8) + (20* 8) + (6*8) =
800+160+48=
1008 gallons of fuel are needed.
Answer:
21
Step-by-step explanation:
Answer:
x = 21
Step-by-step explanation:
(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.
You can bring the cube root to the other side of the equation.
1. I chose to bring it to the other side of the equation, making it a cube.
(3x+1) ^1/3 = 4
(3x+1) = 4^3
(3x+1) = 4 * 4 * 4
(3x+1) - 1 = 64 - 1
3x/3 = 63/3
x = 21
A) Vectors are usually given in the form (x , y), therefore the x-component of v is 1.
B) Similarly to point A), the y-component of w is 6
C) the magnitude of the vector v+w is given by:
√[(x₁ + x₂)² + (y₁ + y₂)²] = √[(1 + (-2))² + (-3 + 6)²] = √(1 + 9) =√10
D) Compute -2 · v = (-2·1 , -2·(-3)) = (-2 , 6) = w
Therefore options B) and D) are true.
