Solve for x given two sides

Solution

x is an angle hence we are gonna use the formula Sin

Sin 0 = opp/hyp

0 represents theta.


Sin 0 = opp/hyp
Sin 0 = 27/33

Put 27/33 in decimal form

= 0.8181

Transpose to make 0 the subject


Sin 0 = 0.8181

0 = Sin-1 0.8181

When adding Sin from one side to another it becomes Sin inverse.

0 = Sin-1 08181

Now we find the answer

0 = Sin-1 0.8181

= 54.89 degrees

Therefore x is equal to 54.9 to the nearest tenth.

The scatterplot for number of enrollments, N, in a sports club, t years after the

year 2006. The equation of the line of the best fit is N = 62t + 35. Find the residual

for the number of enrollments in year 2020 if the actual enrollment is 885

students.

Answers

Answer:

13.7 years

Step-by-step explanation:

The equation of the line of the best fit is N = 62t + 35

where

N is the number of enrollments

t is years after the  year 2006

If the actual enrollment is 885 students. Put N = 885 in the given equation.

885 = 62t + 35

or

885 -35 = 62t

850 = 62t

t = 13.7 years

So, the required answer is 13.7 years.

Step-by-step explanation:

Patrick is riding his bike on a rectangular path around his city.

There is a rest area at each of the path's four corners.

• The city map shows the corners marked with coordinates of (2, 2), (1, 2), (1, -2), and (-2,-2).

Each unit represents 2.5 miles.

What is the perimeter of the path, in miles?

Answers

With the given coordinates it doesn't form a rectangle the correct set of the coordinates should be (2, 2), (1, 2), (1, -2), and (2,-2).

Answer:

The perimeter of the given rectangle that is formed by the given coordinates is 30miles.

Step-by-step explanation:

We are given the Rectangular coordinates such as

(2,2) , (1,2) ,(1,-2) (2,-2)

we will mark these  point on the cartesian planes to understand the rectangle

We can apply the distance formula or we can just look on the cartesian plane to simply get the distance between two points

we get

[(2,2) ,(1,2) ] and [(1,-2) ,(2,-2) ] are two units apart each pair as they are parallel so our width is

W = 2 units

similarly

we now need the length

(1,2) and (1,-2) are four units apart

so our length will be four units

L= 4 units

we need the perimeter

Perimeter of the rectangle = 2( L+W)

                                          = 2( 2 + 4)

                                          = 2* 6 = 12units

Now we are given that 1 unit is equal to 2.5 miles so 12 units will be  

             = 12* 2.5 = 30 miles

Therefore The perimeter of the given rectangle that is formed by the given coordinates is 30miles.

a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are possible if letters and digits cannot be repeated?

Answers

Step-by-step explanation:

Choosing 4 digits out of 10 = 10C4 = 210.

Arranging the 4 digits in 4 places = 4!

Total number of ways to arrange digits

= 210 * 4! = 5040.

Choosing 2 letters out of 26 = 26C2 = 325

Arranging the 2 letters in 2 places = 2!

Total number of ways to arrange letters

= 325 * 2! = 650.

Total number of possible license plates

= 5040 * 650 = 3,276,000.

Answer:

3,276,000

Step-by-step explanation:

10 x 9 x 26 x 25 x 8 x 7 = 3,276,000

the numbers 10, 9, 8, 7 are the spaces available for a non-duplicated digit

the numbers 26 and 25 are for two non-duplicated letters

The number of sunflowers (s) in the garden is one more
than twice the number of roses (r):
is it inequality it not
what's its inequality model—×?? ​

Answers

Answer:

s = 2r + 1

Step-by-step explanation:

Number of sunflower (s) is 1 more than twice the number of roses (r)

Mathematically ;

Number of sunflower = 1 + 2 * number of roses

Sunflower = s ; roses = r

s = 2r + 1

We want to study the relation between the number of sunflowers and roses, we will see that it is an equation and the equation is:

s = 2*r + 1

So we know that the number of sunflowers is one more than twice the number of roses, notice that it represents an equation (so it is not an inequality)

And the equation can be written as:

s = 2*r + 1

The number of sunflowers is 2 times the number of roses, plus 1.
