Answer:
<u>108</u>
Step-by-step explanation:
Volume of a Square Pyramid :
- V = 1/3 x Base Area x Height
Solving :
- V = 1/3 x (6)² x 9
- V = 36 x 3
- V = <u>108</u> cubic centimeters
1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385
The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)
-b/-1= 0.5/-1
Therefore b=-0.5
The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10
Hence, c= 0.01
Answer:
the answer is L. or the last answer
Step-by-step explanation:
you have to find the total area of the place first...
which is 21*17=357
then subtract the inner area (white area) which is
14*20=280
do 357-280 to get the remaining area and the answer is 77ft^2
hope this helps.. vote, comment, thanks, and maybe mark me brainliest lol idk
5/8=0.625
7/12=0.583......
5/8 is bigger as ive put both into a decimal as it is easier to tell
