Which statement about the values 0.034 and 3.40 are true

Nana76 [90]

Answer:

See Explanation

Step-by-step explanation:

This question requires options.

Since none is provided, I will give a general solution.

We have: 0.034 and 3.40

Required

The relationship between them

3.40 can be expressed as:

$3.40 \to 0.034 * 100$

This means that 3.40 is 100 of 0.034

Similarly, 0.034 can be expressed as:

$0.034 \to 3.40 * \frac{1}{100}$

This means that 0.034 is 1/100 of 3.40

The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldes

Angelina_Jolie [31]

Answer:

- September

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

$T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45$

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

$T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45$

$55 = 27\cos{((\frac{\pi}{6})(m-6))} + 45$

$27\cos{((\frac{\pi}{6})(m-6))} = 10$

$\cos{((\frac{\pi}{6})(m-6))} = \frac{10}{27}$

Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.

$\cos^{-1}{\cos{(\frac{\pi}{6})(m-6)}} = \cos^{-1}{\frac{10}{27}}$

Now, with the help of a calculator, in radians:

$\frac{\pi}{6}(m-6) = 1.19$

$\pi m - 6\pi = 6*1.19$

$\pi m = 6*1.19 + 6 \pi$

$m = \frac{6*1.19 + 6 \pi}{\pi}$

$m = 8.27$

8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.
