Answer:

m∠E = 38.7°

Step-by-step explanation:

If you make a drawing it will help.  What you have is a right triangle where you are given the adjacent side to ∠E and the hypotenuse.

The cosine of a angle = adjacent side/hypotenuse.

Therefore cos E = 32/41

arccos (32/41) = 38.7°

Answer:

The answer is 38.7

Step-by-step explanation:

Answer and Step-by-step explanation:

Since we know that this figure is a square pyramid, the base is a square. And the area of a square is its side multiplied by its side, which the sides would equal the same (since it is a square).

So, we square 625 to find One side of the square.

[tex]\sqrt{625} = 25[/tex]

We get 25 as the side.

The volume equation for a square pyramid is:

[tex]V = a^{2}( \frac{h}{3} )[/tex]

Where a is the side length of the base, and h is the height.

Plug in the values.

[tex]V = (25)^{2} (\frac{30}{3} )\\\\V = 625(10)\\\\V = 6250[/tex]

The volume of the square pyramid is 6250 cubic meters.

Answer:

What is the magnitude and direction of the PQ−→− with tail and head points P(-6, 0) and Q(2, 4)? magnitude = √(64+16) = √80 = appr 8.9 , ruling out c.

hope this helps

The magnitude of PQ is 8.9 and PQ is making an angle of 26.57° so 8.9 units, 26.6° north of east will be the correct answer.

A vector is a quantity in which direction and magnitude both matters called a vector.

A vector joining by two points (x₁,y₁) and (x₂,y₂) will be (x₂-x₁)[tex]\hat{i}[/tex] + (y₂-y₁)[tex]\hat{j}[/tex]

The magnitude of this vector will be  

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]  

The direction of this vector will be  

[tex]\\tan^{-1}(\frac{y_2-y_1}{x_2-x_1)}[/tex]

Given P(-6,0) and Q(2,4) so vector joining by

[tex]\vec{PQ}[/tex] = [2-(-6)][tex]\vec{i}[/tex]  + [4-0][tex]\vec{j}[/tex]

[tex]\vec{PQ}[/tex] =  8[tex]\vec{i}[/tex] + 4[tex]\vec{j}[/tex]

now, the magnitude  [tex]\vec{PQ}[/tex] will be

⇒  [tex]\sqrt{(8^2+4^2)}[/tex]

⇒ 8.944

The direction of the vector [tex]\vec{PQ}[/tex] will be

⇒  [tex]\tan^{-1}(\frac{4}{8})[/tex]

⇒26.57°

So, the magnitude of PQ is around 8.944 and the direction is 26.57° from the positive x axis so it's north of the east.

Step-by-step explanation:

From the original question, we can rewrite this as:

An airplane company is determining the difference in selling price if rows of first-class seats are added to a new design. The total selling price for one new row is f(r) = 4,000r. Each row in first class eliminates a pair of rows of economy seats. The total price for each pair of removed rows is e(r) = 1,800r. Which is d(r), the profit or loss for adding r rows of first class seats?

f(r) = 4000r

e(r) = 1800r

d(r) = ? (profit or loss)

Assuming we had added a row of first class seats,

+ f(r) = 4000r

But we had to remove a pair or rows from the economy seats,

- e(r) = 1800r

Translating these into one equation:

d(r) = f(r) - e(r) = 4000r - 1800r = 2200r

Therefore, OPTION A.) d(r) = 2200r

The value of d(r) will be 2200r. The correct option is A.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Step-by-step explanation:

The final cost of meal is $171.35

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of food = $137 . 61

Tip = 18%

tax = 6.5%

Now, price after giving tip

=137.61 x 0.18

= 24.7698

and, after tax

=137.61 x 0.065

=8.94465

Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

Step-by-step explanation:

First, we need to put this standard form into slope-intercept form

To do this you need to move the "y" to all by itself

-25x+25x-20y=100-25x

-20y=100-25x

y=5/4x-5

Answer:

y=5/4x-5

The slope is-5/4 and the -intercept is (0,5)

Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.

25x−20y=100

20y = 100 + 25x

20y=100+25x

y = [tex]5 + \frac{5}{4}[/tex]

She concluded that the slope is   [tex]\frac{5}{4}[/tex]

​and the y-intercept is (0,5).

y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.

The slope is-5/4 and the -intercept is (0,5)

Step-by-step explanation:

The trapezoid midline is the average of the lengths of the bases. Here, the midline length would be ...

The line length shown is 3.5 ft, so the segment shown is not the midline.
