A boat leaves the entrance to a harbor and travels 150 miles on a bearing of N 59° E. How many miles north and how many miles east from the
harbor has the boat traveled?

Answers

N 59° E = 90-59 = 31°

Distance N = 150 sin (31°) = 77.25
Distance E = 150 cos(31°) = 128.58
x=miles north
cos53=x/150
x=90.3 miles north

y=miles East

if the diameter of a circle is 65 what is the area

Answers

Answer:

(4225/4)pi units^2

Step-by-step explanation:

So we need to know the area of a circle formula to find the answer to this question

the formula is A = r^2(pi)

So we have the diameter but we need the radius. The radius is half the diameter so r = 65/2

Now we can plug the radius into the area formula

(65/2)^2*pi =

(4225/4)pi units^2

The number of bacteria on a piece of toast triples every
hour. If there is only one bacteria cell now, how many
will there be in 24 hours?
HELP PLZZZ WILL MARK BRAINLIEST!!!

Answers

Answer:

You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.

Next hour, it triples again so you now have 1 x 3 x 3=9

You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).

Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:

n x 324 where n is the number of bacteria you begin with.

Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer

-6=8+b

b=-14

so then the complete equation would be

Step-by-step explanation:

first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)

1/6 x 7/7 = 7/42

3/7 x 6/6 = 18/42

7/42 + 18/42 = 25/42

2/7 x 6/6 = 12/42

25/42 + 12/42 = 37/42

37/42 + 7/42 = 44/42

44/42 + 18/42 = 62/42

62/42 + 12/42 = 74/42

5/7 x 6/6 = 30/42

74/42 + 30/42 = 104/42

104/42+7/42 = 111/42

111/42 = 2 9/14

Answer:

Step-by-step explanation:

Picture 1

In right triangle ABC,

Side AB is the opposite side of angle C.

Picture 2

In triangle MKL,

tan(∠M) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{KL}{KM}[/tex]

             = [tex]\frac{15}{8}[/tex]

Option (1) is the answer.

Picture 3

In ΔXYZ,

sin(∠Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

            = [tex]\frac{XY}{XZ}[/tex]

For the length of XY we will apply Pythagoras theorem in ΔXYZ,

XZ² = XY² + YZ²

XY² = XZ² - YZ²

      = (40)² - (32)²

XY = √576

     = 24

sin(Z) = [tex]\frac{24}{40}[/tex]

sin(Z) = [tex]\frac{3}{5}[/tex]

Picture 4

In right triangle DEF,

Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{EF}{DF}[/tex]

           = [tex]\frac{75}{72}[/tex]

           = [tex]\frac{25}{24}[/tex]

Picture 5

In ΔABC,

tan(63°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(63°) = [tex]\frac{BC}{AB}[/tex]

AB = [tex]\frac{BC}{\text{tan}(63)}[/tex]

AB = [tex]\frac{8}{\text{tan}(63)}[/tex]

AB = 4.0762 ≈ 4 m

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of campers who voted for hot dogs = 5 campers

Let the number of campers who voted for sphagetti = 4 campers

Now , the total campers = 5 + 4

                                        = 9 campers

5 out of 9 campers vote for hot dogs

So ,

The total number of campers = 72 campers

The equation will be ,

The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72

The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72

                                                                                        = 5 x 8

The total number of campers who voted for hotdogs = 40 campers

Hence , The number of campers who voted for hotdogs is 40 campers

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6
