A 40-foot ladder is leaning against a building that is 12-feet tall. What is the angle of elevation that the ladder makes with the ground? Round your answer to the nearest degree.
Answer:
θ = 17.45°
Step-by-step explanation:
Given that,
Length of a ladder = 40 foot
Height of a building = 12 feet
We need to find the angle of elevation that the ladder makes with the ground.
40 foot will be the hypotenuse and 12 feet will be the perpendicular distance.
Using trigonometry for this:
[tex]\sin\theta=\dfrac{P}{H}\\\\\sin\theta=\dfrac{12}{40}\\\\\theta=17.457^{\circ}[/tex]
So, the angle of elevation that the ladder makes with the ground is 17.45°.
The angle of elevation is [tex]17^\circ[/tex] to the nearest degree
The right-angled triangle formed can be solved for the angle of elevation if we note that
The ladder forms the hypotenuse of the triangleThe wall of the building forms the side opposite the angle we seekSo, the trigonometric ratio to be used here is the [tex]sin\theta[/tex]. That is
[tex]sin\theta=\dfrac{\text{height of the building}}{\text{length of ladder}}[/tex]
substituting the values
[tex]sin\theta=\dfrac{12}{40}\\=\dfrac{3}{10}[/tex]
Now, to find the angle of elevation, [tex]\theta[/tex]
[tex]\theta=sin^{-1} \left(\dfrac{3}{10} \right)\\\approx 17^\circ \text{ (to the nearest degree)}[/tex]

Step-by-step explanation:
Is this correct? If it isn’t what’s the correct answer?
Answer:
No, it is 6.60
Step-by-step explanation:
We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20
We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.
If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.
Answer:
d. $6.60
Step-by-step explanation:
3 cost 3.60, then 5.5 would cost ?
So we have to find what multiplied with 3 would equal 5.5, so:
5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60
3.60 × 5.5/3 = 19.8/3 = 6.6
A messenger entered a building on the ground
(0) floor. He delivered a package to someone on
the 15th floor. That person sent him with a
package to the 3rd floor, who then sent him up
to the 38th floor before finally riding the
elevator all the way back down to the ground
floor to exit. In all, how many floors did the
messenger travel?
The messenger traveled a total of 100 floors while delivering packages.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A messenger entered a building on the ground floor zero.
He delivered a package to someone on the 15th floor which is (0 + 15).
= 15 floors.
That person sent him with a package to the 3rd floor, which is (15 - 3) = 12 floors.
∴ Total floors he traveled (15 + 12) = 27 floors.
who then sent him up to the 38th floor, so from 3rd to 38th he traveled
(38 - 3) = 35 floors.
∴ Total distance he traveled is = (27 + 35) = 62 floors.
Now he is on the 38th floor so, to reach zero level he needs to travel 38 floors.
Total distance traveled by him is = (62 + 38) = 100 floors.

Answer:
Common stockholders received $1,600.
Step-by-step explanation:
Cumulative preferred stock can be described as a type of preferred stock in which dividends not paid in any year accumulate and has to be paid first in future before common stockholders receive any dividends.
Since the dividends paid in cash by Alpha Corporation includes one- year dividends in arrears to preferred stockholders, this implies that the cumulative preferred stockholders have to paid 2-year dividends, i.e. the one-year arrears plus the current year dividend.
Amount received by common stockholders can be calculated as follows:
Amount of dividend paid by Alpha = $10,000
Annual cumulative preferred stock dividend = 1,500 * $40 * 7% = $4,200
Amount received by cumulative preferred stockholders = Annual cumulative preferred stock dividend * 2 years = $4,200 * 2 = $8,400
Amount received by common stockholders = Amount of dividend paid by Alpha - Amount received by cumulative preferred stockholders = $10,000 - $8,400 = $1,600
Therefore, common stockholders received $1,600.

A baker uses 5.5 Ibs of flour daily
The baker's recipe for a loaf of bread calls for 12 oz of flour. If he uses all of his flour to make loaves of bread, how many loaves can he bake in seven days?
Answer:
51.3 loaves of bread
Step-by-step explanation:
Converting 5.5 Ibs to oz (ounces)
1 Ibs =>12 oz
5.5 Ibs => x
Cross Multiply
12 × 5.5 => 88 oz
1 loaf of bread =>12 oz
Hence, in 1 day
12 oz =>1 loaf of bread
88 oz => x
x =>88 oz/ 12 oz
x => 7.3333333333 loaves of bread
Hence, he can make 7.3333333333 loaves of bread in 1 day
Hence, in 7 days
1 day => 7.3333333333 loaves
7 days => x
x => 7 × 7.3333333333 loaves
x => 51.333333333 loaves of bread
Approximately => 51.3 loaves of bread

Nice! Quadratic Equations!
Step-by-step explanation:
Okay, I'll try to keep it as brief as possible.
To find out how many solutions there are in a quadratic equation, we need to find the Discriminate.
It's pretty simple. The form of a quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Our Discriminant is [tex]b^2-4ac[/tex].
Time to solve! (input b=7, a=9, and c=-4)
[tex]49+144\\193[/tex]
The discriminate is positive, meaning there are two answers.
If it was zero, there would be only one.
if it was negative, there would be no solutions.
Time to actually solve!
Completing the square looks to be a bad solution, so I'll go with the Quadratic Equation. Remember, don't use it too often.
(Quadratic Equation: [tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex])
[tex]x=\frac{-7+-\sqrt{49+144} }{18}[/tex]
[tex]x=\frac{-7+-\sqrt{193} }{18}[/tex] <-------SOLUTION! COME HERE!
193 seems to be a prime number, so I can't simplify it any more.
There's your solution!
(Note: +- means plus/minus, where there are two cases, one where the square root has a negative sign, and the other with a positive sign.)
Happy Quadraticing!
