Answer:

x = $\frac{\sqrt{22} }{2}$

Step-by-step explanation:

Using the Pythagorean Theorem we can solve this problem.

The legs of the triangle will be the same (the dashes in the middle of the line indicates they are the same).

The Pythagorean Theorem will look like this:

$a^{2}+a^{2} = (\sqrt {11})^{2}$

Now, let's find a:

$2a^{2} = 11$ The square of a radical will be whatever is under the arch

$a^{2}=\frac{11}{2}$ Divide 11 by 2

$\sqrt{a^{2} } = \sqrt{\frac{11}{2} }$ Square root both sides

a = $\frac{\sqrt{22} }{2}$

Therefore, the length of side x is equal to $\frac{\sqrt{22} }{2}$ .

Hope this helps!!

Logan genetically engineered a new type of fir tree and a new type of pine tree. The combined height of one fir tree and one pin

shepuryov [24]

Answer:

The types of trees that Logan genetically engineered are fir trees 9 meters tall and pine trees 12 meters tall.

Step-by-step explanation:

Given:

The combined height of one fir tree and one pine tree is 21 meters.

The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Now, to find the height of types of trees that Logan genetically engineered.

Let the height of fir tree be $x.$

And let the height of pine tree be $y.$

So, the combined height of both the trees:

$x+y=21\\\\x=21-y\ \ \ .....(1)$

As given, the height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Thus,

$4x=y+24$

Now, substituting the value of $x$ from equation (1):

$4(21-y)=y+24$

$84-4y=y+24$

Subtracting both sides by 24 we get:

$60-4y=y$

Adding both sides by $4y$ we get:

$60=5y$

Dividing both sides by 5 we get:

$12=y\\\\y=12\ meters.$

The height of pine trees = 12 meters.

Now, substituting the value of $y$ in equation to get the height of fir trees:

$x=21-y\\\\x=21-12\\\\x=9\ meters.$

The height of fir trees = 9 meters.

Therefore, the types of trees that Logan genetically engineered are fir trees 9 meters tall and pine trees 12 meters tall.

Gianah lives in Milton. She bought a bus ticket to travel to her cousin's house in Orlando. She gets on the bus in Mobile. The d

kirza4 [7]

Answer: A. 300 - 70h = 30

Step-by-step explanation:

Rest of the question is:

Which of these following equations represents the hours, h, the bus has travelled.

The driver is going at 70 kilometers per hour meaning that for every hour that passes, 70km has been traveled. Expression to find the distance travelled given hours is:

= 70h

There are 300km between the two cities and 30km are left in the journey. Expression is therefore:

300 - 70h = 30

This shows that when you find the distance travelled so far and deduct it from 300, you will get 30km.
