Answer:

Hi there!

The answer to this question is x=79

Step-by-step explanation:

using the triangle sum theorem

you know all angles add up to 180

so in other words: x+(x-17)+39=180

then you simplify: 2x=158

x=79

X+x-17+39=180
2x+22=180
Subtract 22 from both sides
2x=158
X= 79

Well, we know that distance equals speed x time. If the giraffe can run 46.93 feet per second, then by using our equations, we can deduce that the giraffe can run 84.474 feet within 1.8 seconds.

5 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!

ella [17]

Yes, this series converges. We can check using the integral test; we have

$\displaystyle\frac1{25}+\frac1{36}+\frac1{49}+\cdots=\sum_{n=5}^\infty\frac1{n^2}$

and

$\displaystyle\sum_{n=5}^\infty\frac1{n^2}\le\int_5^\infty\frac{\mathrm dx}{x^2}=\frac15$

If you flip a coin and roll a 6-sided die, what is the probability that you will flip a heads and roll at least a 3?

Probability of coin flip = 1/2, probability of die roll = 4/6
1/2 * 4/6 = 1/3 chance
