I still don’t understand this very well I don’t know how to set up the equation. Pls help?
It’s trigonometry
Answer:
[tex] \displaystyle x \approx 47.44[/tex]
Step-by-step explanation:
we are given a right angle triangle
we want to figure out x i.e hypotenuse
in order to do so we can consider trigonometry i.e sin
remember that,
[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex]
given that,theta=21° and opp=17 and hypo=x
Thus substitute:
[tex] \displaystyle \sin( {21}^{ \circ} ) = \frac{17}{x} [/tex]
cross multiplication:
[tex] \displaystyle x\sin( {21}^{ \circ} ) = {17}[/tex]
divide both sides by sin21°:
[tex] \displaystyle x \frac{\sin( {21}^{ \circ} ) }{ \sin( {21}^{ \circ}) }= \frac{17}{ \sin( {21}^{ \circ} ) }[/tex]
By using calculator we acquire:
[tex] \displaystyle x \approx 47.44[/tex]

Find the area of the following colored regions?
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
[tex] \frac{1}{2} \times base \times height[/tex]
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
[tex] \frac{1}{2} \times 6 \times 6 = 18[/tex]
multiply this by 2
[tex]2 \times 18 = 36[/tex]
Now find the area of the whole circle
[tex]area = \pi {r}^{2} [/tex]
our radius is 6, therefore:
[tex]area = \pi {6}^{2} = 113.1[/tex]
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
[tex]113.1 - 36 = 77.1[/tex]
Answer:
Exact Area = 36pi - 36 square meters
Approximate Area = 77.04 square meters (when using pi = 3.14)
================================================
Explanation:
The circle has radius r = 6 meters. The area of the circle is...
A = pi*r^2
A = pi*6^2
A = 36pi
This is the exact area in terms of pi.
Because we have two right triangles, and each right triangle has the same leg length, we can effectively use the SAS theorem to prove the triangles are congruent. Therefore, both of the triangles shown have the same area. One triangle is a rotated copy of the other.
The area of one of the triangles is base*height/2 = 6*6/2 = 18 square meters. That means two of them combine to an area of 18*2 = 36 square meters.
Subtract this from the area of the circle to get the green shaded area
green area = (circle area) - (triangle areas)
green area = (36pi) - (36)
green area = 36pi - 36
This is the exact area in terms of pi. If you want the approximate area, then replace pi with its approximate value. Let's say we go for pi = 3.14
That means,
green area = 36pi - 36
green area = 36*3.14 - 36
green area = 77.04 square meters approximately
Use more decimal digits in pi to get a more accurate area value.

A capacitor holds a 8.89 x 10-7 C
charge when 32.0 V are applied to
it. What is its capacitance?
Answer:2.77*10^-8
Step-by-step explanation:
8.89*10^-7/32.0
The capacitance of the capacitor is approximately 2.78 x 10⁻⁹ Farads (F).
The capacitance of a capacitor can be calculated using the formula:
C = Q / V
Where C represents the capacitance, Q represents the charge stored in the capacitor, and V represents the voltage applied to the capacitor.
In this case, we are given that the charge stored in the capacitor is 8.89 x 10⁻⁷ C and the voltage applied is 32.0 V. Plugging these values into the formula, we get:
C = (8.89 x 10⁻⁷ C) / (32.0 V)
Simplifying the expression, we find:
C ≈ 2.78 x 10⁻⁹ F
The Farad is the SI unit of capacitance, representing the ability of a capacitor to store charge per unit voltage.

) Which object's liquid volume is best measured in milliliters? Bathtub, Milk carton, big spoon or small fish tank
Answer:
big spoon
Step-by-step explanation:
The Big spoon liquid volume is best measured in milliliters.
Given that;
The objects are,
''Bathtub, Milk carton, big spoon or small fish tank''.
We have to find the best objects liquid volume to measured in milliliters.
How to find the appropriate unit for measurement?
Normally we use those measurements which are whole numbers mostly and if not, then not too much long after decimal and not much big numbers.
The volume of Bathtub, Milk carton, and small fish tank is more than the volume of big spoon.
And, The volume of liquid in Bathtub, Milk carton, and small fish tank is has usually measured in liters because it contain more liquid in comparison Big spoon.
Volume of liquid in a big spoon is measured suitably if we use milliliter. It is because the big spoon contains liquid with volume few milliliters or few hundred milliliters.
Hence, We use milliliters for measuring liquid in big spoon.

Standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees. How far from the shore is the ship? Now Pat sights a second ship beyond the first. The angle of depression of the second ship is 5 degrees. How far apart are the ships?
Answer:
(a). 2399.23 meters.
(b). 1944.19 meters apart.
Step-by-step explanation:
We have been given that standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees.
(a) We are asked to find how far from the shore is the ship.
We know that tangent relates opposite side of a right triangle with its adjacent side.
Therefore, the ship is approximately 2399.23 meters away from the shore.
Therefore, the both ships are approximately 1944.19 meters apart.

This question has incorrect answers but the answer that they are looking for is: 24 hours
Step-by-step explanation:
The average is the total hours divided by the number of weeks
So far Emily has 6 hours for the first 3 weeks, x is the number of hours she needs to work in the 4th week.
(6+x)/4=10
6+x = 40
x = 34

Ruby started off her savings account with $100, and $0 in her checking account. She made $95 washing dishes and deposited it into her checking account. She bought a soda for $2 and then transferred $50 into her savings account. How much money is in each account now?
(Note: when you make purchases, like buying a soda, it comes out of your checking account)
A. She has $100 in savings and $95 in checking
B. She has $143 in her savings account and $50 in checking
C. She has $150 in savings and $43 in checking
D. She has $193 in savings and $0 in checking
Answer:
150+93=241
Step-by-step explanation:
I'm not sure if this is correct but i guess because she got 95 and deposited it into her checking she has 95 and judging on if she spent 2 dollars from her savings or checking i assumed it was savings which leaves it with 148 from 100 after depositing 50 - 2 = 148 so basically
edit: nvm i saw the note now im sure but something i dont understand is that if she made 95 how come the answer choices dont say 93 in checking so im guessing you meant 150+43=193
193 is your answer sorry lol took me a while to work this out or Answer choice C
