Step-by-step explanation:

When an observer watches an object lying on the ground from an elevated point on the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF DEPRESSION.

When an observer watches an object from a point on the ground situated at some height from the ground from the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF ELEVATION .

Answer:

i believe it would be z = -7.5

Step-by-step explanation:

Answer:

-7.5

Step-by-step explanation:

Subtract 2.7z from 3.5z

0.8z= -6

divide each term by 0.8 -    0.8 divided by 0.8-         -6 divided by 0.8

Cancel the common factor of 0.8

divide -6 by 0.8

Z= -7.5

when dividing two fractions ex:

(1/3) / (1/6)

we take the reciprocal (we switch the bottom and top numbers) of the second fraction and then change the division into multiplication

(1/3) x (6/1)

multiply across to get

6/3

which is 2

hope this helps

keep the first set if fraction change the divison sign in to a multiplication. and flip the next set of numbers hope this helps

Answer:

3n and -n

7 and -3

Step-by-step explanation:

Answer:

A equals 12

B equals 3

C equals 3+2+(-5)

E equals 4 NI

F equals -7+(-12)=19

Step-by-step explanation:

For A, you have to do the parenthesis first. I did 2+(-3) which equals -5. Then, I added the 7 to the five and got 12. The reason that it is not 12 is because the +7 is greater than the -5.

For B, I got -3 because -4 - (-1) equals 3. The reason that it is three is because when you look at the positive negative chart, you can see that negative and negative equal positive. So, the answer would be 3.

For E, I got 4 NI because when I multiplied the 2*2 I got 4 then you add the numerals Ni. I am not 100% on this problem, that is kind of my guess.

Finally for F, I got 19. My equation above explains it. Once again, you have to add the parenthesis first, so, -7+(-12) equals 19. Like I said above. If you look at the negative positive chart, the number would be positive because both numbers are negative.

I forgot C above, so here it is. For C, I got the equation above by putting the numbers together. For instance, in the problem on the side, for C, it says -10=3+2. If you just add 3+2, you are going to get 5. I added negative five to it and there you go, you get negative ten.

The first and second problems are equal because 3 goes into 12 equally.

Answer: (x-6)= -5

(x+4)= -1

Step-by-step explanation:

The reminders when Polynomial P(x) is divided by (x -6) and (x +4) are -5 and -1 respectively.

An algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).

Given, P(x) is a polynomial. Here are a few values of P(x).

P(-6) = 3, P(-4) = -1, P(4) = 2, and P(6) = -5

The remainder theorem says that:

“When a polynomial p(x) is divided by (x−a), the remainder is p(a).

Since, p(6) is -5 and p(-4) is -1

Thus, the remainder when P(x) is divided by (x – 6) is -5

the remainder when P(x) is divided by (x + 4) is -1

Therefore, When Polynomial P(x) is divided by (x -6) and (x +4) the reminders would be -5 and -1 respectively.

Answer: y-100= 0.25(x-160)

Step-by-step explanation:

Given: Charge per mile = $0.25

Total amount driver pays = $100

Number of miles he drove = 160 miles

Total cost = Flat fee +  ( Number of miles he drove) (Charge per mile) ...(i)

i.e. 100= Flat fee +  (160)(0.25)

⇒ Flat fee = 100 - (160)(0.25)

If y= total cost , x= number of miles, then

y= ( 100 - (160)(0.25))+ (x)(0.25)  [Substitute value of flat fee in (i)]

⇒ y= 100 - (160)(0.25)+ (x)(0.25)

⇒ y-100= (x)(0.25)- (160)(0.25)

⇒  y-100= 0.25(x-160)

Hence, the required equation:  y-100= 0.25(x-160)

Answer:

12:1 or 1:12

Step-by-step explanation:

For every 1 non fiction there is 12 fiction or for every 12 fiction there is 1 non fiction

The required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

Given that,
Emily read 24 fiction books and 2 nonfiction books.
To determine the ratio of the number of fiction books she read to the total number of books that she read.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of fiction books  = 24
number of nonfiction books = 2
Total number of books = 24 + 2 = 26
The ratio of a fiction book to the total number of books,
= 24 / 26
= 12 / 13

Thus, the required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

Answer:

16

Step-by-step explanation:

2(5) + 3(2)=

2x5=10

3x2=6

10+6=16

The value of the expression 2x+3y, when x = 5 and y = 2 is 16.

Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, we have to find the value of the expression 2x+3y,

when x = 5 and y = 2.

To obtain the value of 2x+3y, when x = 5 and y = 2 we'll substitute 5 in place of x and 2 in place of y.

2x + 3y.

= 2(5) + 3(2).

= 10 + 6.

= 16.

Yes ok.

10x+2=32

     -2     -2

10x=30

/10     /10

x=3

Your Answer is

Answer:

x=3

Step-by-step explanation:

the first step is to subtract 2 from both sides because you want to isolate the variable, and the opposite of addition is subtraction. so, you do 10x + 2 = 32, and when you subtract 2 from both, you get 10x = 30. then, because 10 and x are being multiplied together, you want to divide both sides by 10 to get x alone. so, you get x = 30/10, so x = 3.
