First you do the exponents so 10^-3 is:
1/10^3 (change it so it is not a negative exponent, so make it its reciprocal)
1/(10*10*10) = 1/1000 = 0.001
Answer:
1/8 cm = 0.125 cm = 1.25 mm
6 * (1.25 mm)^2 = 9.375 mm^2
Answer:
|h-13| ≤ 2
Step-by-step explanation:
The difference between the height of the plant (h) and show size (13 in) can be written as ...
h - 13
This value is allowed to be positive or negative, but its absolute value must not exceed 2 inches. Thus, the desired inequality is ...
|h -13| ≤ 2
So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
