Answer:

C.tan 44° = y over 110

Step-by-step explanation:

Took the test

The height of the lighthouse is 106.5m

Using the given diagram, we get

tan 44° = y / 110

0.965 = y / 110

y = 0.965 * 110 = 106.5m

The answer is 106.5m

The height of the object. The angle at which the observer views the topmost point of the object (angle of elevation) The angle at which the observer views the object when the observer is on top of a tower/building (angle of depression).

Answer:

3x-24

Step-by-step explanation:

because 3x-24 divide both side by co efficient of x which is 3 so 24/3=8

Answer: $80

Step-by-step explanation:

Let the original price of the refrigerator be represented by y.

We are told that an appliance store reduced the price of a refrigerator by 20%. This will be:

= y - (20% of y)

= y - (20/100 × y)

= y - (0.2 × y)

= y - 0.2y

= 0.8y

We are then told that the store then raised the prices by 10% from the lower price. This will be:

= 0.8y + (10% of 0.8y)

= 0.8y + (0.1 × 0.8y)

= 0.8y + 0.08y

= 0.88y

Since we told that now the price was $70.49, this means that we have to find the value of y using the above expression. This will be:

0.88y = $70.49

y = $70.49/0.88

y = $80.10

y = $80 approximately

The original price of the refrigerator is $80.

Answer:

≈37.7 feet

Step-by-step explanation:

I'm assuming he goes diagonally.

We can form a triangle with legs 20 feet and 32 feet.

Using the Pythagorean Theorem, we get:

[tex]20^2+32^2=c^2\\400+1024=c^2\\1424=c^2\\c^2=1424\\c=\sqrt{1424}\\[/tex]

c≈37.7

Answer: 37.7 ft

Step-by-step explanation:

20^2 + 32^2 = C^2 where c squared is the distance of the diagonal distance that  he wants to walk.

20^2 +32^2 =c^2

400 +1024 =c^2

1424 = c^2

c= 37.7359  rounded to the nearest tenth of a foot is 37.7

Answer:

x = 70

Step-by-step explanation:

Angles on a line add up to 180 degrees.

180 - 120

= 60

Angles in a triangle add up to 180 degrees.

180 - 50 - 60

= 70

Answer:

m < 1 = 80

m < 2 = 70

Step-by-step explanation:

As we can see in the figure that

[tex]a || b[/tex]

Plus line s and t are considered to be transversals

That results into

m < 1 and 80

i.e alternate angles

And as we know that alternative angles are equal to each other

So,

m < 1 = 80

Moreover,

m < 2 = 70

As corresponding angles are equal to each other

Therefore the m < 1 = 80 m < 2 = 70 could be computed easily by applying the above things

Answer:

4

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given

[tex]a_{n}[/tex] = 11 +(n - 1)4 , then

d = 4

The recursive formula allows a term in the sequence to be found by adding d to the previous term, thus

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 4

Answer:

She got one set.

Answer:

a. p= 36/(m + 1)

b. p = 3

Step-by-step explanation:

If p varies inversely as (m + 1)

then p = k × 1/(m + 1). {Where k is the constant}

when p = 4, m = 8, that means 4 = k/(8 + 1)

4 × 9 = k and k = 36

a. Therefore the equation is p= 36/(m + 1)

b. When m = 11,

p = 36/(11 + 1)

p = 36/12

p = 3

Answer:

x = 1

Step-by-step explanation:

Given

3(x - 2) + 2 = 5(x - 3) + 9 ← distribute and simplify both sides

3x - 6 + 2 = 5x - 15 + 9

3x - 4 = 5x - 6 ( subtract 5x from both sides )

- 2x - 4 = - 6 ( add 4 to both sides )

- 2x = - 2 ( divide both sides by - 2 )

x = 1

Answer:

188 balloons

Step-by-step explanation:

First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:

9632 / 86 = 112 balloons

She sold 112 balloons.

We know that she threw 76 balloons away, therefore, the number of balloons she bought was:

112 + 76 = 188 balloons

Answer:

Ok,(-5,__) means that -5 is the x intercept and the missing number is the y intercept

So, We need to substitute x with -5 in the equation to get the value of y

x-5y=-15

-5-5y=-15

-5y=-15+5

-5y=-10

-5y/-5=-10/-5

y=2

So,the missing value is 2. (-5,2)

Answer:

Triangle ABC is not a right-angle triangle.

Step-by-step explanation:

perimeter of the triangle: 20cm

AB=7cm and BC=4cm.

We can do the third length (AC) by subtracting the known lengths from the perimeter: 20 - 7 - 4 = 9

Therefore, the length AC is 9.If

ABC were a right angle triangle, we'd be able to use Pythagoras's Theorem to work out the length AC.

AC is the hypotenuse of the triangle because it is the longest length.

a2 + b2 = c242 + 72 = 16 + 49 = 65

Where AC = c, c2 = 65 If c = 9, then c2 = 81, however when using Pythagoras, c2 = 65.

I hope this helps. I am sorry if you get this wrong.

Answer:

Third option is the right choice.

Step-by-step explanation:

The intersection point of both lines is [tex](-2, 2)[/tex].

Area of triangle  [tex]\Rightarrow 12.5 = \frac{5\times x}{2}[/tex]

[tex]\Rightarrow x=5[/tex]

This represents the height of the triangle.

So, the y-coordinate of C, will be y-coordinate of point of intersection plus height of triangle.

y = 5+2 = 7

Answer:

It's  the first choice - causal, positive correlation.

Step-by-step explanation:

The further you run the more calories you will burn so there is a positive correlation here.

The relationship between distance run and calories burned is generally expected to be causal and positive, but it may be influenced by various individual and contextual factors.

Here, we have,

The relationship between distance run and calories burned is expected to exhibit a causal - positive correlation. This means that as the distance run increases, the calories burned are also expected to increase. The more someone runs, the more energy they expend, leading to a higher calorie burn.

However, it's important to note that while this relationship is expected to be causal and positive, there can be individual variations. Factors such as an individual's weight, metabolism, running efficiency, and other physiological factors can influence the calorie burn. Additionally, other factors such as running speed, terrain, and intensity of the run can also affect the relationship.

In summary, the relationship between distance run and calories burned is generally expected to be causal and positive, but it may be influenced by various individual and contextual factors.

Answer:

f(x) = -2x² + 2

Step-by-step explanation:

If you remember the y = x² parent graph, you will be able to derive your equation from visualization.

The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.
