Answer:
1. Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion, Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.
2. Local winds blow between small low and high pressure systems. Local winds blow over a very limited area, while large scale winds blow over very unlimited area.
Step-by-step explanation:
Answer:
do you mean height, because then the answer would be a length of 9 and height of 6
Step-by-step explanation:
9+9=18
6+6=12
18+12=30
D. 25% as there are 8 sections and two wanted outcomes this can be simplified into a 1/4 so 1/4=25%
You don't need 3 equations to get a general solution. To do this use the equations x-3y-z=0 and -x+2y+0z= -3. Start out by letting z = t. Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3. But since z=t, then -y=-3+t or y=3-t. Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t. So a general solution for this would be (9-2t, 3-t, t)
Answer: E.) 41.95m
Step-by-step explanation:
Area (A) = 85 square meters
Length (L) = a
Width (W) = (a - 10) meters
Area of rectangle(A) = Length (L) × Width (W)
85 = a × (a - 10)
85 = a^2 - 10a
a^2 - 10a - 85 = 0
Using quadratic equation solver :
a = 15.488088482 or a = −5.488088482
Since a cannot be negative, a = 15.49m
Therefore, Length (L) = 15.488m
Width(W) = a - 10 = (15.488 - 10) = 5.488m
Perimeter of rectangle(P) :
P = 2 (L + W)
P = 2 (15.488 + 5.488)
P = 2(20.976)
P = 41.952m
P = 41.95m
