Someone plz help me :(

Step-by-step explanation:

what is the problem here, what do you not understand ?

you do know fractions, and how to multiply and divide them ? because that would be a precondition for a teacher to give you such a problem to solve.

so, if you do know the handling of fractions, this is very basic and easy thing to solve.

let's get into it then :

2 similar triangles. that means all lengths of all lines in one triangle are the result of multiplying the corresponding lines in the other triangle by a constant factor.

that is the meaning of a scaling factor.

it is like on a map, where it says 1 unit on the map is that many units out there in reality.

your teacher was really nice to point out the right angles and even a second angle (37 degrees), so that we can immediately see, which side or line of one triangle corresponds to which side or line of the other.

when we imagine now to turn e.g. the smaller triangle so that it is oriented the same way as the larger one, we see that QS corresponds to LJ. and QR to LK. and RS to KJ.

so, we are going in the scaling process from left to right. that means we are starting with the larger triangle and turn it into the smaller triangle.

so, what (scaling) factor do I need to multiply with 15 to get 10 ?

it is the same factor to go also from 9 to 6 and from 12 to 8.

15×x = 10

x = 10/15 = 2/3

15 × 2/3 = 30/3 = 10

12 × 2/3 = 24/3 = 8

9 × 2/3 = 18/3 = 6

so, as you can see, 2/3 is the correct scaling factor.

Step-by-step explanation:

the polynomial can be factorized by r^2 and then use the quadratic formula

Answer:

answer D hypotenuse

Step-by-step explanation:

Answer: x = 6, y = 2, (6,2)

Step-by-step explanation:

Let number 1 be "x."

Let number 2 be "y."

The difference between two numbers is 4. --> x - y = 4

Twice the greater number is equal to 3 times the lesser number increased by 2 --> 2x = 3y + 2

This problem can then be solved just like any other system of equations.  I will use the elimination method.  Let me know if you prefer substitution.

[tex]2x - 3y = 2\\2x - 2y = 4\\0 - y = -2\\y = 2[/tex]

Then, substitute 2 for y.

x - 2 = 4

x = 6

Hope it helps :)

Answer:

Your answer is 15.

Step-by-step explanation:

x + 10 ,  x = 5

5 + 10

15

Hope this helps!

Answer:

15

Step-by-step explanation:

[tex]x=5[/tex]

Given the information, plug in 5 to where the [tex]x[/tex] is.

5 + 10

Now, simply add.

5 + 10 = 15

Therefore, 15 is the answer.

Answer:

[tex]y = 2x + 12[/tex]

By the fiftieth year, there will be 112 wolves ([tex]y = 2[/tex] × [tex]50 + 12[/tex])

Step-by-step explanation:

You start with 12 wolves in the population.

Each year, the wolf population will increase by 2 years.

Let x represent the number of years.

Let P represent the total population.

Considering all this, P = 2x + 12.

In this case, we want to find how many wolves will be in the population in 50 years. Therefore, we will need to plug 50 into the equation in place of x.

P = 2(50) + 12

Simply to get your answer.

Answer:

The extra monthly charge for the family would be $14.50

Step-by-step explanation:

let x equal the additional monthly charge for legal services

[tex]10 + (25 + x)12 = 484 \\ 10 + 300 + 12x = 484 \\ 310 + 12x = 484 \\ 12x = 174 \\ x = 14.50[/tex]

Answer:

25000000 is the correct answer

Answer:

7/10

Step-by-step explanation:

140/200

the zero at the back of 140 will cancel the zero at the back of 200

2 divide 14=7

and 2 divide 20 =10

so;

140/200

=7/10

Answer:

0

Step-by-step explanation:

If it takes 6 to 10 minutes to make something it's impossible to make it in less than 6 minutes. (the probability is 0)

mathamatically, you can use the CDF for a uniform distribution and get the same answer

(6-6)/(10-6)= 0

0.32 is the answer to 64^1/2 x 10^-2

Answer:

15+t

Unless you already have the answer for what t equals, that's your answer.

15+t

.

Answer:

19

Step-by-step explanation:

it is 19 because, if you have 10 marbles, and then your friend has 9 and gives it to you, then you go from 10 then 11 then 12 then 13 then 14 then 15 then 16 then 17 then 18 then 19.

Answer:

21

Step-by-step explanation:

9 = 3 x 3

10 = 5 x 2

3 x 2 = 6

3 x 5 = 15

15 + 6 =21

Answer:

61

Answer:

<b= 48 degree

Step-by-step explanation:

<A + <B + <C = 180 degree (Sum of angles in a triangle)

<A = 90 degree

<B = 2x + 14 degree

<C = 4x - 26 degree

[tex]90+2x+14+4x-26=180 degree\\2x+4x=180+26-90-14\\6x=102\\x=\frac{102}{6} \\x=17 degree\\[/tex]

Therefore, <B = 2x + 14 = 2(17) + 14 = 34 + 14 = 48

<b = 48 degree
