each interior angle= 168°

<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>

the number of sides the polygon has.

<h3><u>solution</u><u>:</u></h3>

180- 360/n= 168

12= 360/n

n= 360/12

n= 30

Step-by-step explanation:

Given

See attachment

Required

Find RST

To do this, we use:

RST + 36 = 180 --- angle on a straight line

Make RST the subject

RST =- 36 + 180

RST =144

<em>Hence, the measure of RST is 144</em>

Kaapo is mixing Kona beans and Maui beans to make 25 pounds of coffee blend. Kona beans cost Kaapo $15 per pound and Maui beans
son4ous [18]

Answer:

<u>Kaapo will use 17.5 pounds of Kona beans and 7.5 pounds of Maui beans for his blend to cost him $ 17.70 per pound.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the problem correctly:

Number of pounds of the coffee blend = 25

Cost of Kona beans = US$ 15 per pound

Cost of Maui beans = US$ 24 per pound

Cost of the coffee blend = US$ 17.70 per pound

2. How many pounds of each coffee bean should Kaapo use for his blend to cost him $17.70 per pound?

Let's build our equation to answer the question, this way:

x = Number of pounds of Kona beans for Kaapo's blend

25 - x = Number of pounds of Maui beans for Kaapo's blend

Number of pounds of Kona beans for Kaapo's blend * Cost of Kona beans +  Number of pounds of Maui beans for Kaapo's blend * Cost of Maui beans = Number of pounds of the coffee blend * Cost of the coffee blend

Replacing with the real values, we have:

15x + 24 (25-x) = 17.70 * 25

15x + 600 - 24x = 442.50

-9x = 442.50 - 600

-9x = -157.50

x = -157.50/-9

x = 17.50 ⇒ 25 - x = 7.50

<u>Kaapo will use 17.5 pounds of Kona beans and 7.5 pounds of Maui beans for his blend to cost him $ 17.70 per pound.</u>

What is the value of D to the nearest tenth ?
Naily [24]
<span> If two secants intersect from a point outside of the circle, then you can use formula:

26(26 + d) = 22(22 + 40)
676 + 26d = 22 * 62
26d = 1364 - 676
26d = 688
d = 688/26
d = 26.5   </span>←  to the nearest tenth
