Let (3x+24) represent the measure of an obtuse angle. what are the possible values of x?
Fofino [41]
An obtuse angle is an angle with more than 90 degrees and less than 180. so, we can add < 180 and > 90 to the expression, making it the inequality 180 < 3x + 24 > 90. we then solve.

3x + 24 > 90 and 3x + 24 < 180
3x > 66 and 3x < 156
x > 22 and x < 52

so x can be anything more than 22 and less than 52 (it cannot be 52 or more or 22 or less)

hope this helps!

What will 0.16 be as a fraction?
nata0808 [166]

The six is in the hundredths place so we will out the fraction as “over a hundred”, meaning 16/100. But this can be simplified to 4/25 :)

So 4/25 is your answer

4. Han's younger sister is riding her tricycle in a straight line. After 3 s, her speed is 0.5 m/s. After 5 s, her speed is 1.5
liberstina [14]

Answer:

Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.

Step-by-step explanation:

Let suppose that Han's younger sister accelerates at constant rate, then, acceleration (a), measured in meters per square second, can be calculated by the following equation:

a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}

Where:

t_{o}, t_{f} - Initial and final times, measured in seconds.

v_{o}, v_{f} - Initial and final speeds, measured in meters per second.

If we know that t_{o} = 3\,s, t_{f} = 5\,s, v_{o} = 0.5\,\frac{m}{s} and v_{f} = 1.5\,\frac{m}{s}, the acceleration of the younger sister is:

a = \frac{1.5\,\frac{m}{s}-0.5\,\frac{m}{s}  }{5\,s-3\,s}

a = 0.5\,\frac{m}{s^{2}}

Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
