Simplify the expression in part C, and explain what the number means with regard to the problem.

Answer:

52.6 degrees

Step-by-step explanation:

tan^-1(72/55)

Angle of elevation is equals to 52°7'(approximately).

" Angle of elevation is the angle between the horizontal plane and  line of sight from the point of observation."

Formula used

In a right angled triangle,

tanθ = ( opposite side) / adjacent side)

According to the question,

As shown in diagram

Height of the building (AB) = 72m

Distance between base of the building and point of observation

(BC)= 55m

Angle of elevation = θ

Substitute the value in the formula we have,

 tanθ = AB / BC

          = 72 / 55

⇒ θ = tan⁻¹ (72 /55)

      = tan ⁻¹(1.3091)

      = 52° 7' (approximately)

Hence, angle of elevation is equals to 52°7'(approximately).

Answer:

5) 52

6) $190.73

Step-by-step explanation:

5)

Let the unknown number be x.

40 is 77% of x

40 = 0.77x

Divide both sides by 0.77

x = 52

Answer: the number is 52.

6)

We first calculate the amount of tax which is 6.875% of $178.46.

6.875% of $178.46 =

= 0.06875 * $178.46

= $12.27

The amount of tax is $12.27.

Now we add the amount of tax to the price before tax.

$178.46 + $12.27 = $190.73

A is the answer, i.e at the cost, c of $250.

Step-by-step explanation:

0.08c = 0.05c + 7.5

0.08c - 0.05c = 7.5

0.03c = 7.5

c = 7.5/0.03 = 250

Answer:

False

Step-by-step explanation:

Let us evaluate the problem using the proper order of operation:

           4x − 2(5x − 1)

To solve this problem, we use the order of operation called PEMDAS;

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Now, since operations inside the parentheses are of the utmost priority, let us solve this;

             4x − 2(5x − 1)

            = 4x - 10x +2

            = -6x + 2  or 2 - 6x

We see that the solution give is false.

Answer:

2:7

Step-by-step explanation:

Answer:

y-intercept: -4 or (0, -4)

x-intercept: 3 or (3, 0)

Step-by-step explanation:

4x - 3y = 12

we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept

4x - 3y = 12

-3y = -4x + 12

y = 4/3x - 4

So the intercept is -4 or (0, -4).

For the x-intercept, we can make the y value 0 to solve for x.

4x - 3y = 12

4x - 3(0) = 12

4x = 12

x = 3

So the x-intercept is 3 or (3, 0).

Answer:

Part A: 15.55

Part B: 0.45

Step-by-step explanation:

Part A:

The giraffe is already 14.29 so when you add the length of its tongue (equation 14.29 + 1.26) then that would equal 15.55

Part B:

The giraffe is trying to eat some leaves that are 16 feet above the ground so you would subtract 16 - 15.55 to see how much farther it needs to reach, so the answer is 0.45.

(This is what I got, I apologize if I get this wrong. If I messed up on something, someone please correct me, thank you and have a nice day!)

Answer:

Part A:   It can reach 15.55 feet.

Part B:   Need to reach 0.45 feet farther to get to the leaves of a 16 feet tree.

Step-by-step explanation:

giraffe + tongue = reach

      14.29 + 1.26 = 15.55

tree height - giraffe reach = extra distance

16 - 15.55 = 0.45 feet

Answer:

25 pieces

Step-by-step explanation:

Given

[tex]Box_1 = 3\frac{1}{3}[/tex]

[tex]Box_2 = \frac{5}{6}[/tex]

[tex]Pieces = \frac{1}{6}[/tex] yard

Required

Determine the number of pieces

First, we need to determine the total yards of paper

[tex]Total = Box_1 + Box_2[/tex]

[tex]Total = 3\frac{1}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{10}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{20 + 5}{6}[/tex]

[tex]Total = \frac{25}{6}[/tex]

Divide by the size of the pieces to get the number of pieces

[tex]Number = Total/Pieces[/tex]

[tex]Number = \frac{25}{6} / \frac{1}{6}[/tex]

[tex]Number = \frac{25}{6} * \frac{6}{1}[/tex]

[tex]Number = \frac{25}{1} * \frac{1}{1}[/tex]

[tex]Number = 25[/tex]

Answer:

[tex]S(h)=16h+46[/tex]

Step-by-step explanation:

We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].

So we get the answer of: [tex]S(h)=16h+46[/tex]

Answer:

The second graph

Step-by-step explanation:

t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)

The second graph represents the solution set to t > 4 or t < -1.

In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.

According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.

We know when we represent less than or greater than in the number line we represent it as an open circle.

So, t > 4 will be represented by an open circle on the number line starting at 4  but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.
