A sailor on Ship A measures the angle between Ship B and the pier and finds it to be 39°. A sailor on Ship B measures the angle between Ship A and the pier and finds that it is 58°. What is the measure of the angle between Ship A and Ship B?


The measure between Ship A and Ship B is

Answers

Answer 1

Answer:

[tex]83^{\circ}[/tex]

Step-by-step explanation:

Let [tex]C[/tex] be the point that denotes the pier.

[tex]m\angle B=58^{\circ}[/tex]

[tex]m\angle A=39^{\circ}[/tex]

The angle between A and B is C

[tex]m\angle A+m\angle B+m\angle C=180^{\circ}\\\Rightarrow m\angle C=180^{\circ}-(m\angle A+m\angle B)\\\Rightarrow m\angle C=180^{\circ}-(58^{\circ}+39^{\circ})\\\Rightarrow m\angle C=83^{\circ}[/tex]

The measure of the angle between Ship A and Ship B is [tex]83^{\circ}[/tex].

Elena bought 8 tokens for $4.40. At this rate: 1)How many tokens could she buy with $6.05? 2) How much do 19 tokens cost?

Answers

11 tokens.
Step-by-step explanation:
First you need to find how much each token costs.
to do this, we need to divide the cost by the number of tokens.
4.40 ÷ 8 = 0.55. So, each token costs 55 cents/ $0.55.
Next, you need to find how many tokens she can afford.
to do this, we need to divide how much money she has by the cost of each token.
6.05 ÷ 0.55 = 11. So, she can buy 11 tokens in total.

Answer: She could buy 11 tokens and 19 tokens cost 10.45

Step-by-step explanation:

divide how much money you spent by how many tokens you bought

4.40/8=0.55 x 19= 10.45

6.05/0.55=11

Answers

Answer:

7(2 +5)

Step-by-step explanation:

Both the numbers (14 and 35) have a GCF (greatest common factor) of 7. If you divide both numbers by 7, you get 2 and 5. Therefore, your answer would be 7(2 +5)

Answer:

I guess it is A because it is the closest to the answer for the expression 14 + 35.

Step-by-step explanation:

The points are:

[tex]A(-2, 5)[/tex]

[tex]B(-2, -7)[/tex]

[tex]C(-6, -4)[/tex]

Considering the sides as vectors, we have:

[tex]\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}[/tex]

Once

[tex]\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)[/tex]

[tex]\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)[/tex]

[tex]\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)[/tex]

[tex]\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}[/tex]

[tex]\Vert \overrightarrow{AB} \Vert = \sqrt{x^2 + y^2} = \sqrt{0^2+(-12)^2} = \sqrt{144}= 12[/tex]

[tex]\Vert \overrightarrow{CB} \Vert = \sqrt{x^2 + y^2} = \sqrt{4^2+(-3)^2} = \sqrt{16+9}= 5[/tex]

A study compared the number of years of education a person received and that person's yearly salary. It was determined that the relationship between these two quantities was linear and the correlation coefficient was 0.91. Which conclusion can be made based on the findings of this study?

Answers

Answer:

Salary earned increases as the number of years of education earned increases.

Step-by-step explanation:

Given that the correlation between the number of years of education a person receive and his yearly salary yields a linear relationship with a correlation Coefficient of 0.91, this shows that a strong positive relationship exists between the two measured quantities, this is deduced by the positive nature of the correlation Coefficient value obtained and the fact that the value of the Coefficient is close to 1. Hence, salary earned increases as the number of years of education increases and Vice versa.

David loves to cook! He knew 21 recipes before starting cooking school and he learns 2 recipes
every 1 one week. An equation to represent that is y = 21 + 2x where x represents number of
weeks and y represents number of recipes.
His friend Sarah believes that if he attends school for 10 weeks that means he knows 42 recipes.
Explain if she is correct.

Answers

Answer:

Sarah is incorrect.

Step-by-step explanation:

By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.

Answer:

Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.

Step-by-step explanation:

To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:

y = 2x + 21

42 = 2(10) + 21

42 = 20 + 21

42 [tex]\neq[/tex] 41

Sarah is wrong.

longest side must be less than the sum of the legnths of the other 2 sides


if we assume that 7 is longest then missing side is x so

whole number to satisfy is
x=5

if we assume the missing side is the largest
3+7>x
10>x
x is 9 at most


if the third side is not the longest side, it can be 5 at minimum
if the third side is the longest side, it can be 9 at max

so the third side can be 5,6,7,8,9 ft

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answers

Answer:

[tex]Volume = 18312.48[/tex]

Step-by-step explanation:

Given

[tex]Height (h) = 18mm[/tex]

[tex]Radius (r) = 18mm[/tex]

Required

Determine the volume

The volume of a cylinder is calculated as thus:

[tex]Volume = \pi r^2h[/tex]

Substitute values for r and h

[tex]Volume = 3.14 * 18^2 * 18[/tex]

[tex]Volume = 18312.48[/tex]

Hence, the volume of the cylinder is 18312.48mm³

find the domain of (5y-8)/11

Answers

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

The domain of the function f(y) = (5y - 8)/11 is the set of all real numbers.

Dom(f(y)) = R.

What is the domain and range of a function?

Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x  is defined.

Given a function f(y) = (5y - 8)/11.

It is a real function and the domain of the function is the set of all real numbers.

There are no restrictions as the denominator is constant and no such values of 'y' make the denominator zero.
