Answer:

Length of side LM = 9 units

Length of side AC = 9 units

Length of side LN = 15 units

Step-by-step explanation:

Given:

In Δ LMN

Length of side LM = m

Length of side LN = a

Length of side MN = 15

In Δ ABC

Length of side AB = 6

Length of side BC = 9

Length of side AC = m

Find:

Length of all missing sides

Computation:

We know that both triangle are similar using AA rule

So,

Length of side LM / Length of side MN = Length of side AB / Length of side BC

Length of side LM / 15 = 6 / 9

Length of side LM = [6 x 15] / 9

Length of side LM = 90 / 9

Length of side LM = 9 units

Length of side LM = Length of side AC = m

Length of side AC = 9 units

Length of side MN / Length of side LN =  Length of side BC / Length of side AC

15 / Length of side LN =  9 / 9

Length of side LN = 15 units

Answer:

$12,800

Step-by-step explanation:

42-18= 24

24 is the years the money is growing.

24/4=6

Suppose you roll a fair, six-sided number cube.
Serga [27]

Answer:

Sample space= S= {1, 2, 3, 4, 5, 6}

One possible event is rolling an even number

probability (even number)=P\{2, 4, 6\} =\frac{3}{6}=\frac{1}{2}

Step-by-step explanation:

Sample Space

The simple space is the combination of all possible outcomes

so,

Sample space= S= {1, 2, 3, 4, 5, 6}

One possible event

One possible event is rolling an even number

Probability of that event

to find the probability of the event i.e. rolling an even number, we first find the sample for the event i.e. event space

event space={2, 4, 6}

Now,

probability (even number)=P\{2, 4, 6\} =\frac{3}{6}=\frac{1}{2}

pls There are (4^9)^5 ⋅ 4^0 books at the library. What is the total number of books at the library? A.4^9 B. 4^45 C. 4^46 D. 1  
jekas [21]
We know that there are (4^9)^5 ⋅ 4^0 at the library, so we just need to simplify this to get the answer.
(4^9)^5 ⋅ 4^0
=(4^9)^5×1
=(4^9)^5
=4^9×5
=4^45. As a result, the total number of books at the library is 4^45 books at the library or B is the final answer. Hope it help!
