What does pamdas satands for?

*Correction: It's PEMDAS, not PAMDAS*

P of PEMDAS = Parenthesis

E of PEMDAS = Exponent

M of PEMDAS = Multiplication

D of PEMDAS = Division

A of PEMDAS = Addition

S of PEMDAS = Subtraction

PEMDAS is to remember the precedence of the mathematical operations given above. In other words, what operation to perform first can be remembered by using PEMDAS.

Example:

3 + 4*2

As M (multiplication) comes before A (addition) in PEMDAS, therefore, first solve for multiplication of 4 and 2 and then add the resultant of 4*2 in 3:

3 + 8 (as 4*2 = 8) <--- Multiplication (M)

11 (as 3+8 is 11) <--- Addition (A)

Likewise use PEMDAS for complex expressions like (3+5)*2/3+7 by applying the precedence mentioned above.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
