Number 6 part a &amp; b<br> Number 7<br> Please &amp; thank you
miv72 [106K]

Answer:

6- Part A: 750a+1200r=1000000

    Part B: 1065a+876r=1000000

Solution of the system: a\approx521.739\;\;\;\;b\approx507.246

Step-by-step explanation:

<u>Part A:</u>

In words, the equation is formed like this:

Total kg of Arabica + Total kg of Robusta = Total kg of coffee

Now, the total of each yield is calculated by the product of kg/hectare and number of hectares. Thus, the equation is:

750a+1200r=1000000

<u>Part B:</u>

In words:

Arabica's worth + Robusta's worth  = plantation worth

Each yield's worth is given by the product of the price per kg and the corresponding production. So, the equation is:

1.42(750a)+0.73(1200r)=1000000\\1065a+876r=1000000

The diameter of a semicircle is 6 miles. What is the semicircle's perimeter?
koban [17]

Answer:

15.42mi

Step-by-step explanation:

Use the formula for a semicircle's perimeter.

P=\frac{1}{2}\pi *d+d

Plug in 6 for d.

P=\frac{1}{2}\pi*6+6

Let's use 3.14 for \pi, just to make it easier, but of course, if it states to round it to something else, just plug in that many values for \pi.

P=\frac{1}{2}(3.14)*6+6 \\ \\ P=1.57*6+6 \\ \\ P=9.42+6 \\ \\ P=15.42
