the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average

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. 34% 6. $190.73

Step-by-step explanation:

trust man just trust

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

Answer:

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:

216

Step-by-step explanation:

240 - 240(.10)

= 240 - 24

= 216

Alternative method:

240(.90) = 216

A is equivalent to B because if you flip or reflect A, then translate A it overlaps.  

1. Draw A's reflection below it: as if you flipped it.

2. Take the drawing and draw it mirroring B

3. Once you draw the second drawing if you moved, translated, it it would fit over the shape of the B polygon.

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:

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:

[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:

Step-by-step explanation:

Given that the owls heart weighs 1.072 grams

and the Whale's heart weighs 400lbs

let us convert from pounds to grams to have a uniform unit

400lbs = 181,437grams

Now when two readings or quantities are two orders apart it means that they differ by a factor of 100

let us solve for the difference between the two hearts

181,437grams- 1.072 grams= 181 435.928 grams

the difference is more than two orders, hence the statement is not correct

Answer:

x=25°, y=18°

Step-by-step explanation:

Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!

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.
