find the angle whose cosine is .4203

Answers

Answer 1

The cosine of 1.137020412 degrees is 0.4204.

Answer 2

The angle is approximately 65.09 degrees or 1.106 radians.

To find the angle whose cosine is 0.4203, we can use the inverse cosine function, denoted as [tex]cos^{-1}[/tex]or arccos.

Ensure your calculator is in degree mode.Input 0.4203 into your calculator.Use the arccos function to find the angle.

The result will be:

[tex]cos^{-1}[/tex](0.4203) ≈ 65.09°

This means the angle whose cosine is 0.4203 is approximately 65.09 degrees or 1.106 radians.

Answers

Given that ∠A and ∠B are complementary, and ∠B and ∠C are complementary We prove that ∠A ≌ ∠C:By definition of complementary angles, m∠A + m∠B = 90° and m∠B + m∠C = 90°.

Then, m∠A + m∠B = m∠B + m∠C by the substitution property of equality.

Subtract m∠B from each side. You get m∠A = m∠C or ∠A ≅ ∠C

The slope of the graph of the equation y=2x-2 is 2. What is the y-intercept?

y-intercept =

Answers

The equation y = 2x-2 can be written as y = 2x+(-2)

Adding a negative number is the same as subtraction. Eg: 2+(-3) = 2-3

The equation y = 2x+(-2) is in the form y = mx+b where
m = 2 is the slope
b = -2 is the y intercept

Therefore the final answer is simply -2

The graph crosses the y axis at -2 on the vertical number line. The y intercept as an ordered pair is (0,-2). The x coordinate is always 0 for the y intercept.

Answer:

-2

Step-by-step explanation:

-2 is indeed correct, props to my man above me that did all that hard work.

math question down below

Answers

for the first drain the equation you need would be: 2n = 108

for drain B your equation would be: 5n = 108

these are your equations because a number times the amount of water the drain drains per minute will equal 108

to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes

Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water

Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it

Graph y= 12x–3 .
Where would I put the points ?

Answers

We need to graph y = 1/2x - 3.
y = 1/2x - 3 is from the general form of a linear function y = ax + b, in which a represents the slope, b the y-intercept, and x and y the coordinates of 2 points.
Since it's a linear function, the graphical representation of that equation is a straight line.

To graph that function, we need at least 2 points from that line. And we'll find their coordinates using the equation.

1- For x = 0, y = -3 (Since the y-intercept is b = -3).
2- For x = 2. y = 1/2x - 3 = 1/2*2 - 3 = -2

So we now have the 2 points A (0, -3) and B (2, -2).Place those points on the graph, and reunite them with a line and you'll get your graphical representation of the linear function y = 1/2x - 3 (You can see the graphical representation in the image alongside my answer).

Hope this helps! :)

Answer:

Look at my picture, it will show you where to plot the points, and you can also see the green checkmark above which verifies that this answer is correct. Hope this helps!

Step-by-step explanation:

This answer is in the picture. Also, it is not y = 12=-3, it's y = 1/2x-3

The person who asked this question copy pasted and the computer didn't put the symbol with the fraction.

Anyways, this is the correct answer for the problem, so make sure you look at the picture, and I hope I helped you! :)

How to convert 18 gallons/1 hour to cups and minutes

Answers

so there are 2 things you need to convert, the first is the gallons to cups and the second is the hours to minutes. so I like to set it up with numerators and denominators and then multiply the ratios. All same terms will cross out and be opposite of each other.

(18 gal/1 hour) x (1 hour / 60 minutes), now we have (0.3 gallons/1 minute) we just have to change gallons to cups

(0.3 gallons/ 1 minute) x (4 quarts/1 gallon) x (2 pints/1 quart) x (2 cups/1 pint)

this comes out 4.8 cups/1 minute

The perimeter of this Hexagon is 162 cm. Each longer side measures 1 cm more than twice a shorter side. Find the length of the labled x.

Answers

The length of the shorter side [tex]$ x $[/tex] is 20 cm.

The length of each shorter side labelled [tex]$ x $[/tex] in the hexagon is 20 cm. Here's the step-wise calculation:

1. Let [tex]$ x $[/tex] represent the length of the shorter side.

2. The length of each longer side is given as [tex]$ 1 $[/tex] cm more than twice a shorter side, so it is [tex]$ 2x + 1 $[/tex] cm.

3. The perimeter of the hexagon is the sum of the lengths of all its sides, which is given as [tex]$ 162 $[/tex] cm.

4. Since the hexagon has four shorter sides and two longer sides, the perimeter [tex]$ P $[/tex] can be expressed as:

[tex]\[ P = 4x + 2(2x + 1) \][/tex]

5. Plugging in the given perimeter value and simplifying the equation:

[tex]\[ 162 = 4x + 4x + 2 \][/tex]

[tex]\[ 162 = 8x + 2 \][/tex]

6. Solving for [tex]$ x $[/tex] gives:

[tex]\[ 160 = 8x \][/tex]

[tex]\[ x = \frac{160}{8} \][/tex]

[tex]\[ x = 20 \][/tex]

Therefore, the length of the shorter side [tex]$ x $[/tex] is 20 cm.

Answers

Best to worst;

8.34/6 = $1.39

7.95/5 = $1.59

12.53/7 = $1.79

5.97/3 = $1.99

Answer: 5.97 for three cans > $12.53 for seven cans > $7.95 for five cans > $8.34 for six cans

Step-by-step explanation:

Since, $12.53 for seven cans

The cost of one can = [tex]\frac{12.53}{7} = 1.79[/tex]

$5.97 for three cans

The cost of one can = [tex]\frac{5.97}{3} = 1.99[/tex]

s$7.95 for five cans

The cost of one can = [tex]\frac{7.95}{5} = 1.59[/tex]

$8.34 for six cans

The cost of one can = [tex]\frac{8.34}{6} = 1.39[/tex]

Since, 1.99 > 1.79 > 1.59 > 1.39

Therefore, the required order of prices,

5.97 for three cans > $12.53 for seven cans > $7.95 for five cans > $8.34 for six cans

write each equation in standard form using integers. y=2x+5

Answers

standard form : Ax + By = C

y = 2x + 5....subtract 2x from both sides
-2x + y = 5...multiply by -1 to make x positive
2x - y = -5 <=== standard form

To write the equation y=2x+5 in standard form with integers, subtract 2x from both sides to get -2x + y = 5. Then, multiply by -1 to make the coefficient of x positive, resulting in 2x - y = -5.

To write the equation y=2x+5 in standard form using integers, we start by moving the terms involving x and y to one side of the equation and the constant term to the other side. The standard form of a line in two dimensions is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

The given equation is already pretty close, so we subtract 2x from both sides to obtain:

-2x + y = 5

Now, we want A to be non-negative. If A is negative, we can multiply the entire equation by -1 to make A positive.

So, the equation -2x + y = 5 becomes 2x - y = -5 when multiplied by -1. This is now in standard form, with all coefficients being integers.

To find the students in the group, simply add up the frequency from each mark. I'll give you an example solution, but I challenge you to do this on your own!

For example, say that there are 4 students with 3 marks and 6 students with 4 marks. There are then 4+6=10 total students in the group

To find the mean, simply add up all up the marks with the amount of frequencies and divide it by the amount of students.

Take our example from earlier - we can write it as a list. Since there are 4 students with 3 marks, we have
3, 3, 3, 3 ( 3 four times)
Since there are 6 students with 4 marks, we have
4, 4, 4, 4, 4, 4 (4 six times)

Add them all up, and divide them by the total amount of students (10) to get
(3+3+3+3+4+4+4+4+4+4)/10=(3*4+4*6)/10=36/10=3.6

Good luck, and feel free to ask questions if you're confused!

Students are planning a 3 day hiking trip in the mountains. The hike covers a distance of 18.5 kilometers. The students hike 0.28 of the total distance the first day. If they split the remaining distance equally between the second and third days how far will they hike on day three?

Answers

The students will hike 9.11 KM on day three.

Answer:

They hike 9.11 km on day three

Step-by-step explanation:

Total distance traveled on a 3 day hiking trip in the mountains = 18.5 km

The students hike 0.28 of the total distance the first day.

So, Remaining distance = 18.5 - 0.28 = 18.22

Now we are given that they split the remaining distance equally between the second and third days

So, Distance traveled by them on third = Distance traveled by them on second day = Half of the remaining distance = [tex]\frac{18.22}{2} = 9.11[/tex]

So, they hike 9.11 km on day three
