A hardware store sold 630 lawn mowers in one year. If 441 lawn mowers were purchased in the spring, what is the ratio of the num

AlekseyPX

Answer:

$Ratio = 0.7$

Step-by-step explanation:

Given

$Total = 630$

$Spring = 441$

Required

Determine the ratio of lawns in spring to total

$Ratio = Spring:Total$

$Ratio = 441 : 630$

Convert to fraction

$Ratio = \frac{441}{630}$

$Ratio = 0.7$

<em>Hence, the ratio of lawns sold in spring to the total is 0.7</em>

Step-by-step explanation:

a= the number with the highest power, in this case it is x^2. Therefore, a=1.

b= the number with the second number, the one that has an x. Therefore, b=3.

c=the last number, the one with no variable. therefore, c=10

What is the value of h(a) when a = 2 in the

Ivahew [28]

<h3>Answer: 3</h3>

=========================================================

Explanation:

This is the given piecewise function

$h(a) = \begin{cases}3a+2 \text{ when } a > 3\\4a+5 \text{ when } a = 3\\3 \text{ when } a < 3\\\end{cases}$

We can rewrite things like this

$\text{when } a > 3, \ \ h(a) = 3a+2\\\text{when } a = 3, \ \ h(a) = 4a+5\\\text{when }a < 3, \ \ h(a) = 3\\$

I personally prefer this format better because it mentions the inputs first, and that leads to which function definition we go for.

The input a = 2 fits the description of $a < 3$ since $2 < 3$ is a true statement. Therefore we go for the third line and can see that $h(a) = 3$ becomes $h(2) = 3$

-----------

As another example, if we had the input a = 7, then we'd go for the first line (since 7 > 3) and get

h(a) = 3a+2

h(7) = 3(7)+2

h(7) = 23
