Answer:

23.7°

Step-by-step explanation:

To obtain the value of AB ; Use the cosine rule ;

Recall:

c² = a² + b² - 2ab Cos C

c² = 24² + 11² - 2*24*11 Cos75

c² = 576 + 121 - 528 * 0.2588190

c² = 697 - 136.656432

c² = 560.343568

c = sqrt(560.343568)

c = 23.6715

Hence, c = AB = 23.7°

Answer:

40ft

Step-by-step explanation:

Add up all four sides of your rectangle:

15ft + 15ft +5ft + 5ft = 40ft

You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.

Answer:

she walks about 145.7 meters in 5 minutes

Step-by-step explanation:

Hey There!

so first we want to find the meters per second rate

to do this we do

[tex]\frac{12}{24.7} = 0.48582995951[/tex]

so the meters per second is 0.4858299591

Then we want to find how many seconds are in a 5 minutes

to do this we multiply 5 and 60

5x60=300

then we want to multiply that by the meters per second

300x 0.4858299591=145.748987854

so she walks about 145.7 meters in 5 minutes

Answer:

3/16

Step-by-step explanation:

If an article takes half of the page then;

1article = 1/2 of a page

3/8 of the article = x

Cross multiply

1×x = 1/2×3/8

x = 3/(2×8)

X = 3/16

Hence the photo takes 3/16 of the magazine

The period of an function, is how many times it takes to complete one cycle, if the period is 2π then after 2π the function would have been completed one entire cycle, but what I mean by cycle?

It's when the function start again, these functions are called periodic functions for a reason, after between that interval, the function goes up, goes to 0 again, go down and finally goes zero again, it means a cycle! the function goes up, down and then return to the same point.

If you look at the picture, the function took 2π just to go up and zero, it needs more 2π to go down and return to zero, then it's period is 4π.

The bottom function complete its cycle in just π!

I hope you liked it, maybe the draw will help you!

Answer:

$1,560

Step-by-step explanation:

6% of $750 = $45

$45 times 18 = $810

$810 + $750 = $1,560

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values,  that doesn't work. That would not be a function.

This example is a function.

Answer:

x = 69

y = 69

Step-by-step explanation:

Since AB is parallel to CD

x = 69 ( They are alternate angles)

and

y = 180 - 111 ( Co - interior angles)

y = 69

Step-by-step explanation:

Answer:

median- 58.5

first quartile- 56

third quartile- 65

interquartile range- 9

Step-by-step explanation:

median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

Answer:

30

Step-by-step explanation:

Right angle = 90 degrees

180-90 = 90, hence the right side of the equation.

x+37+x+67 = 90

2x + 104 = 90

2x = -14

x = -7

Plug in x.

-7+37 = 30 (angle a)

Angle a  = 30

Answer:

angle A = 30 degrees

Step-by-step explanation:

*All triangles have an interior angle that adds up to 180 degrees

The triangle is the picture is a right triangle so one of the angles is 90 degrees.

First, we must figure out what "x" is:

⇒ 180 = 90 + x + 37 + x + 67

Combine like terms:

⇒ 180 = 2x + 194

Subtract 231 from both sides:

⇒ 180 - 194 = 2x + 149- 194

⇒ -14 = 2x

The divide both sides by 2:

⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]

⇒ -7 = x

Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:

⇒ x + 37

⇒ -7 + 37

⇒ 30

To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):

⇒ 90 + x + 37 + x + 67 = 180

⇒ 90 + (-7) + 37 + (-7) + 67 = 180

⇒ 180 = 180
