Answer:
Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d
c = 30
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle = 
*
= 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8 
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
*
* 10 = 282.7
The answer is 8.
explanation: if g=5, you would simply multiply 4x5 which is 20. then you would subtract 20-12 which gives you 8:)
Answer:
The inequality is 6 + 3x ≤ 12 or x ≤ 2 .
Step-by-step explanation:
Given that $6 is for admission which is a fixed amount, $3 is charged per hour and must not spend more than $12. So the inequality will be :
Let x be the no. of hours,
6 + 3x ≤ 12
Solve :
6 + 3x ≤ 12
3x ≤ 12 - 6
3x ≤ 6
x ≤ 6 ÷ 3
x ≤ 2
Answer:
Option (3)
Step-by-step explanation:
In a right triangle,
Cosine rule → 
Sine rule → 
In the given triangle,
By cosine rule,
Or cos(h°) = z ÷ x
Therefore, Option (3) will be the answer.
Answer:
A) 1/9, 3, 27
Step-by-step explanation:
i think you mean 3^x (and not 3x).
because otherwise none of the answer options withdraw makes any sense.
3^-2 = 1/(3²) = 1/9
3¹ = 3
3³ = 27
