The lines shown below are perpendicular. If the green line has a slope of
2/5 , what is the slope of the red line?

Answers

Answer 1

Answer:

-5/2

Step-by-step explanation:

for perpendicularity;

[tex]m1 = \frac{ - 1}{m2} [/tex]

where m1 is first slope

and m2 is second slope

so here, let m1 be green line slope

and m2 be red line slope

thus,

[tex]m2 = \frac{ - 1}{m1} [/tex]

[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]

[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]

A door is 6 feet 6 inches high and 38 inches
wide.Can a thin mattress, 7 feet wide, be carried
through the door diagonally? How do you know
for sure?

Answers

The mattress can fit through the door.
The door is 78 inches tall and 38 inches wide. If you do the Pythagorean theorem with these numbers you get the hypotenuse of 86.76, which is larger than the width of the mattress.
38^2+78^2=c^2
1444+6084=7528
Take square root of 7528, which is 86.76

What is the mathematical
representation of 20P4?

Answers

the answer for 20p4 is c

The mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?

We can use combinations for this case,

The Total number of distinguishable things is m.

Here, Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times,

So, total number of choices in that case would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called permutation of k items chosen out of m items (all distinct).

We have to find the mathematical representation of 20P4.

[tex]^{20}P_4[/tex]

here, m = 20

k = 4

Now substitute;

[tex]^mP_k = \dfrac{m!}{ (m-k)!}\\\\^{20}P_4 = \dfrac{20!}{ (20-4)!}\\\\^{20}P_4 = \dfrac{20!}{ (16)!}\\\\\\^{20}P_4 = \dfrac{20 \times 19 \times 18 \times 17 \times 16!}{ (16)!}\\\\\\^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]

Hence, the mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

For the first two use the formula [tex]A^2 + B^2 = C^2[/tex]

[tex]15^2 + 36^2 = C^2(unknown)[/tex]

Calculate 15 x 15 + 36 x 36 = 1521

Now its

1525 = C^2

Fins the squeare root of 1521 whitch is 39

and square c^2 as well whitch make it C^1 or simple C

This give us a final anwser of the missing side

39 = C

Second triangle

For this the formual is different since we are not finding the lenght of the hypotunus (C), we know this becauee the missing angle is met my a 90 digree angle.

Here the equasion is  C^2 - A^2 = B^2

WE will it in again

15^2 - 9^2 = B^2

Calaulate 15 x 15 - 9 x 9 = 144

Now its 144 = B^2

Again we find the square root for each side

Square root of 144 is 12

and Square root of B^2 is Simpley B

We put in togethe to find the final anwser whitch is

12 = B

For the last two it is simple

All angles of a triangle added together must always equal 180 degrees

So it the two side are 75 and 32 we add them (75+32) to get 107

Now we just subtract that amount (107) form 180 to get the third missing angle. 180 - 107 = 73  

Here the missing angle is 73

One way to know if this is correct is to add all side and see if it equaels 180

75 + 32 + 73 = 180

For the second question it seems to be exactly the same as the first in the photo so the anwser would also be 73.

Hope this helps! :)

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

The left side of the triangle is 20 units long, the bottom portion is 8 units long.

This means the top portion must be 12 units long, 20 - 8 = 12.

The ratio between the left and right side has to be the same because they are two straight lines.

So if the ration is 8 to 6 or 8/6 which reduces to 4/3 then your ration is 12 to x.

So if... 4/3x=12 then

(3)4/3x = 12(3) multiply both sides by 3

4x = 36 the divide both sides by 4

x = 9

To check you can multipy your answer, in this case 9 by 4/3.

(9)(4/3)  =

(9 x 4)/3 =

36/3 = 12
