He have to buy 4 bags to put all the dirt at once.
Step-by-step explanation:
Radius = 17 inches
Height = 28 inches
Volume of dirt from the cylindrical hole = π(r x r) h
= π(17 x 17) 28
= (3.14) (289) 28
= 25408.88 cubic inches
1 foot = 12 inches
Volume of dirt the bag can hold= 24 x 18 x 48
= 20736 cubic inches of dirt
The man fills only one third of the bag.
The volume of dirt the man fills = (1/3)20736
= 6912 cubic inches
Total bags = 25408.88/6912
= 3.69
= appx. 4 bags
He have to buy 4 bags to put all the dirt at once.
A. is the answer. a2 + b2 = c2 is the formula used to find the hypotenuse (the longest leg)
We have to do BIMDAS
so starting with the brackets we do
35+27
which is 62
62÷4×12
then we work left to right for multiplication and division
62÷4
which is 15.5
then we finish with 15.5×12
which is 186
hope it helps.
Answer:
x=-4
Step-by-step explanation:
The two lines are parallel, so the two angles, 45 and x+49 are equal too
Lets make the equation
x+49 = 45
x = 45-49
x = -4
