I need help on this question
If someone could help me please and thank you!

Answer:

The correct option is C

Step-by-step explanation:

I attached an image that forms the complete question.

The converse Pythagorean theorem states that, "If the square of the longest side of a triangle is equal to the square of the other two sides, then the triangle is a right triangle."

That is if c is the longest side of a triangle and then a and b are the other sides, then if,

c² = a² + b², the triangle is a right triangle.

Looking at all the options, option C fits the theorem well. Because

3² + 4² = 5² implies the triangle is a right triangle and the converse theorem is established.

The option D also looks close, but it's not correct because you can just draw any two sides and put the right angle in between them. The longest is always the part of the triangle that is opposite to the right angle, 90°. If for instance, you draw 3 and 5 then put the right angle in between them, 4 will take the position of the longest side which is wrong.

Therefore, the correct option is c.

Answer:

c

Step-by-step explanation:

answer: $11.40

explanation: turn the percent into a decimal, multiply it by the starting cost, then subtract the product from the starting cost

>> 40% = 0.40

0.40 x 19 = 7.60

19 - 7.60 = 11.40

You paid $11.4 for the shirt.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A shirt costs $19 you buy it on clearance for 40% off.

You paid,

= 19 - (19 x 40 / 100)

= 19 - 7.6

= $11.4

Therefore, the amount is $11.4.

Answer:

v = 105°

Step-by-step explanation:

According to Angle Sum Property of a triangle ,

Sum of measure of all the 3 interior angles of the triangle 180°.

Now , lets use this property in this question . So,

[tex]36 + (v - 27) + (v - 39) = 180[/tex]

[tex] = > 2v - 66 + 36= 180[/tex]

[tex] = > 2v - 30 = 180[/tex]

[tex] = > 2v = 180 + 30 = 210[/tex]

[tex] = > v = \frac{210}{2} = 105[/tex]

Answer:

count the number of triangles and then the total number of shapes so if there are 7 triangles and 21 shapes total the answer would be 7-21

Step-by-step explanation:

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The total number of shapes is 9. And the number of triangles is 4.

Then the ratio of the triangles to the total number of shapes will be given as,

Ratio = 4 / 9

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

Answer:

She started with 50 stamps

Step-by-step explanation:

Hi! For these types of problems we always result to going backwards. So, she now has 30 right? So, to reverse into the problem, we do the opposite of what it says. "She then bought five more" 30 - 5 = 25. Then it says she sold half of them. 25 x 2 = 50. If we recheck by going back, she sold half of them (50 / 2 = 25) and she bought five more (25 + 5 = 30).

Hope this helps!

The required amount of sugar is given as 40 grams.

Given that,
A new soft drink has 20% less sugar than before. The drink had 50 grams of sugar originally, how much less sugar it has now is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
According to the question,
The final amount of sugar = [1 - 0.02][50]
                                  = 40 grams

Thus, the required amount of sugar is given as 40 grams.

Answer:

40

Step-by-step explanation:

Answer:

40% (see below)

Step-by-step explanation:

First, make a ratio to simplify your situation:

Think about it like this:

If 25 is 100%, and the question is asking me for 10, which is x%, then what is x%?

Here's what I'm talking about:

10               x%

------    =    --------

25            100%

Now, just cross multiply and simplify:

1000 = 25x

   40 = x

      x = 40

To check your answer, you can multiply 25 by 0.4 (the decimal form of 40%) to see if it worked because 40% of 25 is 10:

25 (0.4)

Answer:

1,187

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as;

an = a + (n-1)d

a is the first term

n is the number of terms

d is the common difference

Given the sequence 3, 11, 19, 27...

a = 3

d = 11-3 = 19-11 = 8

n = 149 (since we need the 149th term)

a149 = 3 + (149-1)(8)

a149 = 3+(148)(8)

a149 = 3+1,184

a149 = 1,187

Hence the 149th term is 1,187
