Find all solutions for a triangle with B=36 degrees, b=19, and c=36. Round to the nearest tenth.
lawyer [7]

we know that

Applying the law of sines

b/sin B=c/sin C-------> solve for sin C

sin C=(c/b)*sin B-----> sin C=(36/19)*sin 36

sin C=1.1137-------> the value of the sines can not be greater than 1

The side lengths and angle given cannot be used to create a triangle

therefore


with the given values ​​there is no solution to form some triangle

Evaluate. 102+6⋅7+8 70142150190
Aloiza [94]
Hi.

102+6(7)+8  (your equation)
102+ 42+ 8  (since the order is PEMDAS, multiplication has to go first. 6x7=42
144 + 8        (since you go left to right, 102 +42 has to be 1st. Answer= 144)
152              (now the only thing left is 144 + 8, so do that. Answer= 152.)

Since that's the last step, 152 will be your answer. 

Hoped I helped and if you need anymore you could always ask me~

Y=3x
Mariulka [41]
So you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3

subtitute x=3 into first equation (y=3x)
y=3(3)
y=9

Suppose the population of a certain city is 3031 thousand. It is expected to decrease to 2246 thousand in 50 years. Find the per
Kipish [7]

Answer:

The rate at which the population decrease is 59.8 %  

Step-by-step explanation:

Given as :

The population of city = 30,31,000

Now The population of city decrease to 22,46,000

The time period in which population decrease is 50 years

Let the percentage rate of decrease = R%

So,

Final population = initial population × (1-\frac{Rate}{100})^{Time}

Or, 22,46,000 = 30,31,000 × (1-\frac{Rate}{100})^{50}

Or, \frac{2246000}{3031000} =  (1-\frac{Rate}{100})^{50}

Or, \frac{2246}{3031} = (1-\frac{Rate}{100})^{50}

(\frac{2246}{3031})^{\frac{1}{50}} = ( 1-\frac{Rate}{100})

So , 0.99402 = ( 1-\frac{Rate}{100})

Or,  \frac{Rate}{100} = 1 - 0.99402

So, Rate = 5.98\times 10^{-3} × 100

Or, Rate = 0.598 = 59.8 %

Hence The rate at which the population decrease is 59.8 %  Answer
