Answer:
81cm
Step-by-step explanation:
15cm + 20cm + 21cm + 25cm = 81cm
Answer:
Both
and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug
into 

The solution verifies the equation.
Step 2: Plug
into 

The solution verifies both equations. Therefore,
is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug
into 

Step 4: Plug
into 

The solution verifies both equations. Therefore,
is another solution to this system.
Answer:
Option D is correct.
Step-by-step explanation:
We need to find the value of sin 34°.
We can find the value by putting it in the calculator
sin 34° = 0.5592
So, Option D is correct.
Answer:
1. 10%
2. 49.1%
Step-by-step explanation:
1. The percent of voters who are other is the number of other divided by the total number of voters.
The number of "other" votes is 222. The number of total votes is 2,222.
The percent is 222/2222 = 0.0999. Times the decimal by 100 for the percent.
0.0999*100 = 9.99% rounds to 10%.
2. The probability is found by finding the number of male and registered as democrat, which is 600, and dividing it by the number of males, which is 1,222.
600/1,222 = 0.4909
Multiply by the decimal by 100 to find the percent.
0.4909*100 = 49.09 which rounds to 49.1%.
