10 minutes before 9 is 8:50. since any time on the hour is at a perfect 60 minutes, you subtract the minutes given and move 1 hour back to find your answer.
for example, if you were asked what 20 minutes before 10 was. you start by subtracting 20 from 60. 60-20= 40, this being your minutes. 10-1 is 9, this being your hour, making the final answer 9:40.
Answer:
6x +4
Step-by-step explanation:
9 + 6x - 5 =
Combine like terms
6x +4
To find the area of a circle, use the following formula; A = πr^2
The radius of a circle is half the diameter.
So;
4.) 18/2 = 9
Radius = 9
(3.14)9^2
9(9) = 81(3.14)
254.34 is the area of figure #4.
5.) 12/2 = 6
A = (3.14)(6)^2
A = (3.14)(36)
113.04(2) Because there are two pizzas.

Number 4 gives the most amount of pizza. So, one 18 in. pizza.
Answer:
B) 3.16 pounds, since two decimal places would indicate the usage of the hundredths place.
Step-by-step explanation:
<span>For 1 sale, an employee earns 1 tokens.
For 2 sales, an employee earns 6 tokens.
For 3 sales, an employee earns 12 tokens.
For 4 sales, an employee earns 19 tokens.
</span>
For the answer to the question above,
Suppose that for x sales the number of tokens the employee earns is:
ax^3 + bx^2 + cx + d
Therefore:
a(1^3) + b(1^2) + c(1) + d = 1
a(2^3) + b(2^2) + c(2) + d = 6
a(3^3) + b(3^2) + c(3) + d = 12
a(4^3) + b(4^2) + c(4) + d = 19
Therefore:
a + b + c + d = 1
8a + 4b + 2c + d = 6
27a + 9b + 3c + d = 12
64a + 16b + 4c + d = 19
Solve that to get:
a = 0
b = 1/2
c = 7/2
d = -3
Therefore, the formula is:
(1/2)x^2 + (7/2)x - 3
