1. Optiond D is correct,  Triangle proportionality theorem can be used to  find a missing length in a right triangle.

2. Option D is correct, the value of x is 6.

1. The  Triangle proportionality theorem can be used to  find a missing length in a right triangle.

The triangle proportionality theorem states that if a line parallel to one side of a triangle intersects the other two sides at different points, then it divides the remaining two sides proportionally.

2. By triangle proportionality theorem:

NO/OP=NM/x

20/8=15/x

Simplify the LHS:

5/2=16/x

Apply cross multiplication:

5x=15×2

5x=30

x=30/5

x=6

Hence, the value of x is 6.

Answer:

13$ per book

Step-by-step explanation:

Divide 65/5 and it will give you the unit rate

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.

Answer:

189$

Step-by-step explanation:

30% of 270 = 81

270-81=189

Answer:

The sale price is $189.

Step-by-step explanation:

Rule:

To find the percent of a number, change the percent to a decimal by moving the decimal point of the percent two places left. Then multiply it by the number.

Example:

Find 20% of 200.

Change the percent, 20, to a decimal by moving the decimal point of 20 two places left.

20% = 0.20

Now multiply 0.20 by 200.

0.20 × 200 = 40

Answer to the example: 20% of 200 is 40

Here is the solution to your problem:

The suit has a regular price of $270.

The percent off is 30%.

First, we find the dollar amount of the discount.

30% of $270 = 0.30 × $270 = $81

The dollar mount of the discount is $81.

Now we subtract the dollar amount of the discount from the original price of $270.

$270 - $81 = $189

Answer: The sale price is $189.

Answer:

SAS because they stand for side angle side

Answer:

A

Step-by-step explanation:

the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5

so the answer should be

-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity    

when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.

for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

Answer:

A

Step-by-step explanation:

(f+g)(x)=-2x+4+x^2-3x+5

The proof of the value of the inverse equation f^-1(50) = 3 is below

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x^3 - 4

To show that f^-1(50) = 3, we simply show that

f(3) = 50

substitute the known values in the above equation, so, we have the following representation

f(3) = 2 * 3^3 - 4

Evaluate

f(3) = 50

Hence, the proof of the value of the inverse equation is done

Answer:

D

Step-by-step explanation:

7a + 6 = -5(a -6)

<=> 7a + 6 = - 5a + 30

<=> 7a + 5a = 30 - 6

<=> 12a = 24

<=> a  = 2

=> Answer is D

Hope this helps!

Answer:

a=2

Step-by-step explanation:

1. distribute the -5 to (a-6): 7a + 6 = -5a + 30

2. add 5a to both sides, and subtract 6 on both sides: 12a = 24

3. divide by 12: a = 2
