To find each box, you have to multiply the number above the box and the number to the left of the box.
For the bottom left, we have 4 x 0.8 or 3.2.
For the bottom right, we have 0.8 x 0.6 or 0.48.
It sum.because <span>basically you are adding them up</span>
Answer:
a = z/mb
Step-by-step explanation:
Given:
To solve for a, divide both sides by the variables mb to isolate a-term.
Simplify the expression and we finally have solved for a-term.
Therefore, the answer to this question is a = z/mb.
Please let me know if you have any questions regarding my answer or explanation!
To solve, you would need to make two equations and substitute one in for the other. Let a = # of adults, and c = # of children
5a + 2c = 1,220
a + c = 295
a + c = 295
-c -c
a = 295 - c
5(295 - c) + 2c = 1,220
1,475 - 5c + 2c = 1,220
1,475 - 3c = 1,220
1,475 - 3c = 1,220
-1,475 -1,475
-3c = -255
-3c/-3 = -255/-3
c = 85
a + c = 295
a + 85 = 295
-85 -85
a = 210

They're trying to trick you with √2. Remember in the 30/60/90 triangle the sides are in ratio 1:√3:2, with the "1" opposite the 30 degrees.
Here we have
1:√3:2 = 6√2:x:hypotenuse
or
x/(6√2) = √3/ 1
x = 6√2×√3 = 6√6
Answer: AC=6√6
