PLEASE ANSWER THESE 2 QUESTIONS ASAP

For the first question, it's 20/60 (if it's a leap year, but tht doesn't rlly matter). That can be reduced to 1/3. However, there's also 5/60 which is reduced to 1/12. Since 1/3 is bigger than 1/12, he shouldn't expect to be able to get around at least 5 of the days. (But, I'm not exactly sure if this answer is correct. Just guess; there's 50% you'll get it correct and 50% you won't.)

For the second question, you first have to convert '56 out of 64 days' thing to percentage. You do 56/64 x 100 which is 5600/64. That equals to 87.5%. Since 90 > 87.5, the train is more reliable.

THE END

Find the area of the iscoseles triangle first answer=brainliest

blsea [12.9K]

Answer:

$60cm^{2}$

Step-by-step explanation:

so first we need to find the height so by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them.

$h^{2} =13^{2} -5^{2}$

$h^{2} =169-25$

$h^{2} =144$

$h=\sqrt{144}$

$h=12$

We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.

area of triangle = $\frac{1}{2}$ x base x height

area of triangle = $\frac{1}{2}$ x 10 x 12

area of triangle = 60

How to solve x+9/5=5/3-x-3/6

Schach [20]

Answer:

x = $-\frac{19}{60}$

Step-by-step explanation:

$x + \frac{9}{5} = \frac{5}{3} - x -\frac{3}{6} \\x + x = \frac{5}{3} -\frac{3}{6} - \frac{9}{5} \\2x = \frac{50 - 15 - 54}{30} \\2x = \frac{-19}{30} \\x= \frac{-19}{30} / 2 = \frac{-19}{30} * \frac{1}{2} \\x= \frac{-19}{60}$

In order for a gear to work in a piece of machinery, the radius of the gear, r, must be greater than 4 cm, but not exceed 4.1 cm

sveta [45]

The compound inequality represents the situation is r > 4 and r ≤ 4.1

<h3>Compound inequality</h3><h3 />

Radius of the gear = r

r must be greater than 4 cm

r > 4

r must not exceed 4.1 cm

r ≤ 4.1

Therefore, r > 4 and r ≤ 4.1 is the compound inequality which represent the situation.
