To find the significant figure you must start from the left.
If you see a 0 then you mustn’t count it and look at the next number.
In this case we have a 9 as the first digit on the left.
We are rounding to 1 significant figure so our answer would be 100000.
Hope this helped!

NEED HELP I SUCK AT GEOMETRY (OFFERING 100POINTS)!!! best answer get brainlest
Andrej [43]

Answer:

g = 3.5

f = 78°

<u>Finding</u><u> </u><u>g</u><u>:</u>

25 is parallel to 8g - 3, so they are equal to each other.

25 = 8g - 3

28 = 8g

g = 3.5

<u>Finding</u><u> </u><u>f</u><u>:</u>

72° create a sum of 180° when adding to (f + 30) because they are supplementary.

72 + f + 30 = 180°

102 + f = 180°

f = 78°

Hope this helps!

Evaluate the following expressions using the chip method. SHOW ALL WORK!!!
Mila [183]

Answer:

  • a. -7
  • b. -20
  • c. 7

Step-by-step explanation:

  • a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
  • b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.
  • c. ---=+

Hope this helps :)!

What is the answer to &gt; solve 4cos (theta/3) -2 = 0, over [0, 4pi)
Vesna [10]

Hello from MrBillDoesMath!

Answer:  

@ =   pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)


Discussion:

Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)

where

4cos(@) - 2 = 0.                Adding 2 to both sides

4 cos(@) - 2 +2 = 2  =>

4 cos(@) = 2                     Divide both sides by 4

cos(@) = 2/4 = 0.5


This implies that @ =   pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)


Thank you,

MrB
