Answer:
The answer is below
Step-by-step explanation:
We have a vector with a magnitude of 75 miles and a direction of 300 °.
To draw it, the first thing is to make a Cartesian plane, the first thing is to know in which quadrant it would be, 300 ° is in the fourth quadrant (270 ° - 360 °), that is, it would be 30 ° (300 ° - 270 °) with respect to to the y axis negative.
Knowing this angle, we calculate the value of x and y, knowing that the magnitude of the vector is 75 miles, that is, this value would be the hypotenuse.
The value on the x-axis can be calculated using the sine of the angle, like this:
sin 30 ° = x / 75
x = sin 30 ° * 75
x = 37.5
Now to calculate the value on the y-axis it would be by means of Pythagoras and it would be:
y ^ 2 = 75 ^ 2 - 37.5 ^ 2
y ^ 2 = 4218.75
y = 64.95, -64.95 because it must be located in the fourth quadrant
Which means that to draw the vector that we are asked to do, we must draw a point from origin (0,0) to (37.5, -64.95).
Then I leave a sketch of what it would be:

Express the recurring decimal 0.004 as a fraction.
Answer: 1/250
Step-by-step explanation:
Given the recurring decimal : 0.004
Firstly:
Let x = 0.004 - - - (1)
Due to the number of decimals places and value of x;
We multiply (1) by 1000 to obtain an integer
Multiply (1) by 1000
1000x = 4 - - - (2)
From (2) we can solve for x and leave our answer as a fraction.
Divide (2) by 1000 to obtain the value of x
1000x / 1000 = 4 / 1000
x = 1 / 250
Recall x = 0.004
Therefore, x = 0.004 = 1/250

*ANSWER PLS, DIFFICULT QUESTION* Wrapping paper costs $0.025 per square inch. If a moving box that is an 8 ½ inch cube is being wrapped, how much would the wrapping paper for this box cost (rounded to the nearest dollars and cents)?
Answer: D $10.84
Step-by-step explanation:
If the box is a cube and paper is needed to wrap it, then we need to find the surface area of the box then multiply it buy the cost of the wrapping paper.
The surface area of a cube uses the formula 6a^2 where a is any side length.
We know that the box has a side length of 8.5 inches.
SA = 6*8.5^2
SA= 433.5
Now multiply the surface area by the money.
433.5 * 0.025 = 10.8375
Round 10.8375 to dollars and cents as it is required.
10.8375 = 10.84
Which means it will cost $10.84 to wrap the box.
Answer:
$10.84
Step-by-step explanation:
The surface area of the moving box is SA = 6s2.
SA = 6(8.5)2
SA = 6(72.25)
SA = 433.50 square inches.
At $0.025 per square inch, it would take 433.50 x (0.025) or $10.84 to wrap this box.

Step-by-step explanation:
Here, we will have to use [tex]LCD[/tex] or, least common denominator.
The least common [tex]LCD[/tex] here that we will be using is going to be 30. We can always make sure by multiplying.
[tex]\frac{3}{10}[/tex]*[tex]\frac{3}{3}[/tex][tex]=\frac{9}{30}[/tex]
Our final answer for the first fraction is [tex]\frac{9}{30}[/tex] which could be simplified back to [tex]\frac{3}{10}[/tex].
For the second fraction, we will be multiplying with [tex]\frac{2}{2}[/tex].
[tex]\frac{2}{15}[/tex]*[tex]\frac{2}{2}[/tex][tex]=\frac{4}{30}[/tex].
Again, it simplifies back to [tex]\frac{2}{15}[/tex].
Hence, the [tex]LCD[/tex] is [tex]30[/tex].

Find the perimeter of the shaded region. Round your answer to the nearest hundredth.
Answer:
20.56 units.
Step-by-step explanation:
Perimeter of the shaded region is the sum of all straight sides and all 4 arcs.
Perimeter of 4 straight sides [tex]=4\times 2=8\text{ units}[/tex]
Perimeter of a arc [tex]=\dfrac{1}{4}\times 2\pi r[/tex]
Perimeter of 4 arcs [tex]=4\times \dfrac{1}{4}(2\pi r)=2\pi r[/tex]
Here, r is the radius. So,
[tex]r=\dfrac{6-2}{2}=\dfrac{4}{2}=2[/tex]
Perimeter of 4 arcs [tex]=2(3.14)(2)=12.56[/tex]
Perimeter of the shaded region = Perimeter of all straight sides + Perimeter of all 4 arcs

Determine the value of z.
Answer:
121°
Step-by-step explanation:
The sum of the a triangle's angles is 180°
so the missing angle: 180°-(87°+34°) = 59°
so z°= 180°-59°= 121°
Answer:
121º
Step-by-step explanation:
Once interior angles of a triangle sum 180º, the remaining angle is:
34º + 87º + x = 180º
x = 59º
Once ∠x and ∠z are supplementary angles (add up to 180º), ∠z = 121º
Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 85 miles per hour. The westbound train
travels at 75 miles per hour. How long will it take for the two trains to be 192 miles apart?
Do not do any rounding.
Answer:
It will take 1 hour and 12 minutes for the two trains to be 192 miles apart
Step-by-step explanation:
The total distance between the two trains is the distance traveled by both trains. The distance traveled by the eastbound train is 85 mph * elapsed time and the distance traveled by the westbound train is 75 * elapsed time.
The combined formula is distance traveled = speed of first train * elapsed time + speed of second train * elapsed time.
Since the elapsed time is equal for both trains then the formula is modified as distance traveled = (speed of first train + speed of second train) * elapsed time.
Solving for the elapsed time
distance traveled = (speed of first train + speed of second train) * elapsed time
192 miles = (85mph + 75 mph) * elapsed time
192 miles = 160 mph * elapsed time
elapsed time = 192 miles / 160 mph
elapsed time = 1.2 hours
elapsed time = 1 hour and 12 minutes
It will take 1 hour and 12 minutes for the two trains to be 192 miles apart.
PLEASE HELP ASAP!!! WILL AWARD BRAINLIEST!! THANKS!! A restaurant offers 6 choices of appetizer, 8 choices of main meal and 5 choices of dessert. A customer can choose to eat just one course, or two different courses, or all three courses. Assuming all choices are available, how many different possible meals does the restaurant offer?
Answer:
377 meals
Step-by-step explanation:
If you choose to have all three courses, then there are 6 choices for the first course, 8 for the second, and 5 for the last, making a total of 6*8*5=240 different possible meals.
If you choose two courses, then there are 3 options. You can pick appetizer and main meal, which would give you 6*8=48 possibilities. You can pick main meal and dessert, which would give you 8*5=40 possibilities. Finally you can pick appetizer and desert, which would give you 6*5=30 possibilities. In total these are 118 different possible meals with two courses.
Finally, you could choose 1 course, which would give you 6+8+5=19 different meals.
In total, this is 240+118+19=377 meals

The assessed value of a property is $ 16,000. If the tax rate is
$8/$100 of value, what is annual tax for the property?
Answer: 1280 dollars
Step-by-step explanation:
Given that the assessed value of a property is $ 16,000.
If the tax rate is $8/$100 of value. That is, 8 dollars in every 100 dollars.
Divide both value of the property by 100.
16000/100 = 160 dollars
Then, multiply it by 8 dollars
8 × 160 = 1280 dollars
The annual tax for the property is therefore, 1280 dollars.
OR
First find the rate or percentage of the tax which will be:
8/100 = 8%
Find the 8% of the value of the property which is 16000 dollars
8/100 × 16000 = 1280 dollars
