Step-by-step explanation:

Two of the three interior angles are known. Both are equal to 55°. This can be seen by looking closely at the picture. To find the third angle subtract the other two from 360°

$360\textdegree-55\textdegree-55\textdegree=x$

Do the same thing only afterward subtract the third angle from 180 to find the supplementary angle

$360\textdegree-40\textdegree-28\textdegree=ans\textdegree\\180\textdegree-ans\textdegree=x$

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Following are the differential equation:

$\to P(C,S)t+1 = P(C,S)t+(- 0.06Ct +0.04St, 0.06Ct - 0.04St ) \ \ \ \\\\or \ \ \ \ \ \ \ \\\\ \to (0.94Ct + 0.04St, 0.96St + 0.06Ct)$

In equation:

$\to t = 0, \ as \ 2019\\\\\to Ct = 10,000,000 \\\\\to St = 800,000,000\\$

$\to P(C, S)1 = (0.94Ct + 0.04St, 0.96St + 0.06Ct) \\\\$

$= (0.94(10000000) + 0.04(800000), 0.96(800000) + 0.06(10000000))\\\\ = (9,400,000 + 32,000), (768,000 +6000000))\\\\ = (9432000, 1368000)$

$\to P(C, S)2 = (0.94(9432000) + 0.04(1368000), 0.96(1368000) + 0.06(9432000))$

$=(8,866,080 + 54,720), (1,313,280 + 565,920)\\\\=(8,920,800, 1,879,200)$

60 students on field trip 20 students were 8th graders. What ratio shows relationship between eighth graders and everyone who we

Flauer [41]

Answer:

Percentage=33.33%

Step-by-step explanation:

Total number of students=Number of 8th grader+others who went on trip

where;

Total number of students=60

Number of 8th graders=20

Others who went on trip=x

replacing;

60=20+x

x=(60-20)

x=40

Others who went on trip=x=40

Ratio of number of eighth graders to the number of everyone who went on the trip is;

Eighth graders who went=20 students

Everyone who went including the eighth graders=60

20/60==1/3

(1/3)×100=33.33%

Percentage=33.33%
