Since there are 100 cents in a dollar, routing to the nearest cent would be rounding to the nearest hundredth. In order to do that you would solve to the thousandths place the use that number to round up or down to the nearest hundredth.
For example:
If a dozen roses cost $12.35, how much does each rose cost?
12.35 ÷ 12 = 1.029
The 9 is in the thousandths place. If it is 5 or higher we round the hundredths place up, so our answer is each rose costs 1 dollar and 3 cents ($1.03)
Answer:
5x^3+6x^2+x-7
Step-by-step explanation:
f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,
f(x)
+ g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7
4x^3 + x^3 + 6x^2 + 3x- 2x - 7
Combine like terms
5x^3+6x^2+x-7
Answer:

Step-by-step explanation:
If the triangles are similar, then the sides are in proportion.
We have the equation:
<em>cross multiply</em>
<em>divide both sides by 3</em>

<em>subtract 8 from both sides</em>
<em>divide both sides by 3</em>

The question is incomplete:
Reyna runs a textile company that manufactures T-shirts. The profit, p, made by the company is modeled by the function p
=
s^2+9s-142, where s is the number of T-shirts sold. How many T-shirts should be sold to earn a profit of more than $2,000?
Answer:
s>42
Reyna needs to sell more than 42 T-shirts.
Step-by-step explanation:
Given that you have to find the amount of T-shirts that should be sold to earn a profit of more than $2,000, you have to find the amount required to earn $2,000 by replacing p with 2,000 and solving for s:
s^2+9s-142=2000
s^2+9s-2142=0
(s+
)^2-2142-(
)^2=0
(s+
)^2=2142+(
)^2
(s+
)^2=2142+
(s+
)^2=

s+
=
s=
s=
s=
s=42
According to this, Reyna needs to sell more than 42 T-shirts to earn a profit of more than $2,000.
