Answer:
A, B, and C
Step-by-step explanation:
a). -6 ÷ 2 x 5 1/3
= -3 x 5 1/3
= -16
b). 24 ÷ (-3) + 1/2
= -8 + 1/2
= -7.5
c). 36 ÷ 4 x (-2)
= 9 x -2
= -18
d). -54 ÷ (-9) x (-3 2/3)
6 x -3 2/3
= -22
Yes
explanation:
5/1 multiplied by 1/8 is 0.625 which is less than 5
It takes $4926.46 to fill the silo with oats, if the silo is 12 meters tall, and its base has a radius of 2 meters. Oats cost $98 per cubic meter.
Step-by-step explanation:
The given is,
A silo is in the shape of a cone
Height of silo - 12 meters
Base radius of silo - 2 meters
Cost of silo - $98 per cubic meters
Step: 1
Formula to calculate the volume of cone,
.....................(1)
Where, r - Radius of cone
h - Height of cone
Step: 2
From the given data,
r = 2 meters
h = 12 meters
Equation (1) becomes,
= (0.33333)(3.1415)(4)(12)
= 50.27 cubic meters
Step: 3
Cost of oats to fill silo = Volume of silo × Oats cost per cubic meters
= 50.27 × 98
= $4926.46
Result:
It takes $4926.46 to fill the silo with oats, if the silo is 12 meters tall, and its base has a radius of 2 meters. Oats cost $98 per cubic meter.
Answer:
8.9x + 6.2 + 8.7 equals..
8.9x + 8.7 + 6.2
8.7 + 8.9x + 6.2
6.2 + 8.7 + 8.9x
Step-by-step explanation:
Addition is a property that can be done in any order. Multiplication can not be moved around. The variable x is tied to the 8.9 with multiplication, so it must always be attached to it. The other numbers can be moved around because it is addition.
