Lisa says that the indicated angles cannot have the same measure. Marita disagrees and says she can prove that they can have the

same measure. Who do you agree with? Justify your answer.
Equations: (9x - 25 + x)°
(x + 50 + 2x - 12)°

I agree with Marita, that the angles could have the same measure.  This can be proven if you set the two amounts equal and solve for x. 

9x - 25 + x = x + 50 + 2x - 12

To begin, we should combine like terms on both sides of the equation to start simplifying the equation.

10x - 25 = 3x + 38

Next, we should subtract 3x from both sides and add 25 to both sides to get the variable x alone on the left side of the equation.

7x = 63

Finally, we should divide both sides by 7, to get rid of the coefficient of x.

x = 9

If you plug in 9 for x in our first equation, you get that both of the angle measurements equal 65 degrees.  This means that Marita is correct, because if x = 9, then the angles would have the same measure.

mr Goodwill [35]

Answer:

75.2 degrees Fahrenheit

Step-by-step explanation:

F =  StartFraction 9 Over 5 EndFraction C + 32

  • Substitute 24 for C.
  • Multiply the value of C by StartFraction 9 Over 5 EndFraction before adding 32.
  • 24 Degrees Celsius is 75.2 Degrees Fahrenheit.

In 2010, a city's population was 1,405,233 and it was decreasing at a rate of 1.1%. At this rate when will the city's population
frez [133]
The equation
                                            P(t) = 1405233 * (1 - 0.011)^(t)
models the population at t years after 2010. Then, when P(t) = 1,200,000, we have
                                 1200000 = 1405233 * (0.989)^t
                                  (0.989)^t = 1200000/1405233
                                                t = log(1200000/1405233)/log(0.989)
                                                t = 14.27 years
This means 14.27 years after 2010. Therefore, the answer to this question is 2024.

A local grocery store tested spinach samples for E coli bacteria using two different tests. The first test has a 94% probability
Readme [11.4K]

Answer:

The probability that both tests detect the bacteria is  83.66% ....

Step-by-step explanation:

First test has a probability of giving accurate results = 94% = 0.94

Second test has a probability of giving accurate results = 89% = 0.89

The probability that both tests detect the bacteria is:

Multiply both the probabilities:

=0.94*0.89

= 0.8366

Converting the value into percentage, we get

0.8366*100

= 83.66%

Thus the probability that both tests detect the bacteria is  83.66% ....
