11) m = 6/5
12) m = 1/4

If m∠2=40°, what is the measure of ∠1 + ∠6?

Answers

Answer:

280 degrees

Step-by-step explanation:

I hope i'm correct.

So because of the rule vertical angles 2 and 5 are both equal to 40 degrees. Based on that we can use the rule supplementary angles (where two angles together equal to 180 degrees) So since 2 equals to 40 degrees, subtract that from 180. 180-40, which is 140. we need to find <1+<6 so because of vertical angles add 140 and 140. Which is 280 degrees.

I hope this helps :)

Find the solution of the system of equations

15x – 10y = -30
5x – 9y = 7

Answers

Answer: x=-4, y=-3

Explanation: We can use the elimination method to make two of the variables cancel out.

For the second question, we can multiply everything by -3 to get -15x+27=-21, where 15x and -15x will cancel out.

Adding the remaining equations will give us 17y=-51 and solving for y gives us y=-3.

If we plug -3 in for y in the 2nd original equation, we get 5x+27=-4, where solving for x will give us x=-4

Let's solve for x.

y=x−1

Step 1: Flip the equation.

x−1=y

Step 2: Add 1 to both sides.

Answer:

x=y+1

---------------------------------

Let's solve for x.

y=−2x−4

Step 1: Flip the equation.

−2x−4=y

Step 2: Add 4 to both sides.

−2x−4+4=y+4

−2x=y+4

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Answers

Answer:

18.6%

Step-by-step explanation:

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Percentage increase is calculated as:

Final value - Initial value/ Initial value × 100

Final value = 510000

Initial value = 430000

Percentage Increase =

510000 - 430000/430000 × 100

= 80000 / 430000 × 100

= 0.1860465116 × 100

= 18.604651163 %

Approximately = 18.6 %

find the solution to the following system of equations using substitution or elimination​

Answers

Answer:

D. (2,-3)

Step-by-step explanation:

if you substitute 2 for the x value and -3 for the y value in both equations, it works out.

instead of y=3x-9 it would be -3=3(2)-9.

you solve and get -3=-3, so it's a solution.

and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.

Read Digital Field Trips to the Grand Canyon.The Grand Canyon is one of Arizona's most well-known tourist attractions. People from all over the world visit this natural wonder every year. It is also a popular field trip for students living close enough to make the journey. For some, though, visiting the Grand Canyon is not easy and is certainly not possible for a field trip. Students living hundreds of miles away may never have the opportunity to visit this world-class destination. That is, until recently. Due to a new program created by the National Park Service, students from all over the world are now able to experience the Grand Canyon. They visit the park through digital field trips.In the past, programs at the park focused on those for physical visitors to the park. To improve access, the park has unveiled a permanent Virtual Studio for Kids to help the "visit" the park. Improvements in green-screen technology have allowed the park to make high quality videos. These videos make students feel like they are right there in the park. Though education programs have been limited for years, students are now able to connect with experts in the park. These experts include park rangers, scientists, geologists, and other experts. Students can now directly ask questions. They can now learn about the Grand Canyon by talking to the professionals that know it best.A major reason that students from across America and the world have been unable to visit the Grand Canyon is the high cost of taking a field trip to Arizona. Teachers in states like New York would have to organize accommodation, travel, and food for students, resulting in an expensive field trip that many schools and students simply cannot afford. The National Park Service has thought of this too. It now offers five different, free interactive presentations for different age ranges. Teachers just need to sign up early in order to secure their spot for this digital field trip.

Larry is considering two investment strategies. The first strategy involves putting all of his available funds in Project X. If Project X succeeds, he will receive a $10,000 return, and if it fails, he will suffer a $2,000 loss. There is a 70% chance Project X will succeed and a 30% chance it will fail. The second strategy involves diversification: investing half of his funds in Project X and half of his funds in Project Y (which has the same payoff structure as Project X). If both projects succeed, he will receive a $5,000 return from Project X and a $5,000 return from Project Y, for a net gain of $10,000. If both projects fail, he will suffer a $1,000 loss on Project X and a $1,000 loss on Project Y, for a net loss of $2,000. If one project succeeds and one fails, he will receive a $5,000 return from the successful project and will suffer a $1,000 loss on the failed project, for a net gain of $4,000. As with Project X, there is a 70% chance that Project Y will succeed and a 30% chance that it will fail. Assume that the outcomes of Project X and Project Y are independent. That is, the success or failure of Project X has nothing to do with the success or failure of Project Y.
