Using the Pythagorean Theorem, it is found that the unknown side length of the triangle is of 7.9 cm.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs $l_1$ and $l_2$ of a right triangle with the length of the hypotenuse h, according to the following equation:

$h^2 = l_1^2 + l_2^2$

Researching this problem on the internet, we have that:

The unknown side length is of a leg of x.

The other leg is of 9 cm.

The hypotenuse is of 12 cm.

Hence:

x² + 9² = 12²

x = sqrt(12² - 9²)

x = 7.9 cm.

The unknown side length of the triangle is of 7.9 cm.

we are given

Jimmy is trying to escape Jane

For finding total distance , we will find distances and then add them

He runs 12 km/hr for 5 minutes

First distance:

speed =12 kh/hr

time=5 minutes

we can change into hour

$t=\frac{5}{60}hr$

$d_1=s*t$

now, we can plug values

$d_1=12*\frac{5}{60}$

$d_1=1$

second distance:

speed =17 kh/hr

time=8 minutes

we can change into hour

$t=\frac{8}{60}hr$

$d_2=s*t$

now, we can plug values

$d_2=17*\frac{8}{60}$

$d_2=2.26667$

third distance:

speed =6 kh/hr

time=2 minutes

we can change into hour

$t=\frac{2}{60}hr$

$d_2=s*t$

now, we can plug values

$d_3=6*\frac{2}{60}$

$d_3=0.2$

now, we can find total distance

$d=d_1+d_2+d_3$

$d=1+2.26667+0.2$

$d=3.46667$

so,

total distance is 3.46667 km...........Answer

Answer:

7.5

Step-by-step explanation:

when implementing the joe mama constant into our quadratic formula, we can solve to find that 7.5 does not uphold when subjected to the same peen coefficient checks that all other values held true for.

Which step is the same in the construction of parallel lines and the construction of a perpendicular line to a point off a line?

chubhunter [2.5K]

Answer:

Both types of lines are built on the same plane although they meet different objectives for which they are built.

Step-by-step explanation:

The difference is that in the case of parallel lines they will never cross and in the case of perpendicular lines if they cross each other, which can give rise to the formation of right angles to each other.

Step-by-step explanation:

Quotient rule,

$a {}^{n} \div a {}^{m} = a {}^{n - m}$

Do this,

a^(n-3)=a^9

Since the exponents have to be the same, this turned into a simple one step equation:

n-3=9

+3 +3

**n = 12, so the final answer is 12.
