Clara and her family are vacationing in the Netherlands. They began a tour of the North Sea coastline at an elevation of
–
8 feet. By the end of the tour, their elevation had decreased by 5 feet. What was their elevation at the end of the tour?

Answer:

30 ft

Step-by-step explanation:

Hi!

So according to the Pythagorean theorem, a^2 + b^2 = c^2

Ok, so let's just plug those numbers in:

18^2 + 24 ^ 2 = c^2

324 + 576 = c^2

900 = c^2

[tex]\sqrt{900}[/tex] = c

[tex]\sqrt{900}[/tex] = 30

x = 30

You could also use Pythagorean triples, and there are Pythagorean triples for this which is 3:4:5; and since it's a ratio, we can write it as 3x:4x:5x. Then, according to a and b, x would equal 6, so then we plug in x:

3(6):4(6):5(6)

and you get:

18:24:30

Let me know if you have any questions.

Answer:

The equation of the line is:

[tex]y -1= 5(x - 2)[/tex]

Step-by-step explanation:

Given

Pass through [tex](2,-1)[/tex]

Parallel to: [tex]y= 5x - 2[/tex]

Required

Determine the equation in point slope form

An equation has a general form:

[tex]y = mx + c[/tex]

Where:

[tex]m = slope[/tex]

Compare: [tex]y = mx + c[/tex] to [tex]y= 5x - 2[/tex]

we have:

[tex]m = 5[/tex]

Since the line is parallel to [tex]y= 5x - 2[/tex], then they have the same slope of 5

The line equation is then calculated using:

[tex]y -y_1= m(x - x_1)[/tex]

Where

[tex]m = 5[/tex]

[tex](x_1,y_1) =[/tex] [tex](2,-1)[/tex]

So, we have:

[tex]y -1= 5(x - 2)[/tex]

Answer:10p−3(−0.9p−0.8)

Answer:

C. 21 pennants

Step-by-step explanation:

35-28=7

7 divided by 1/3= 21/1 or 21

The number of pennants that can be made is given by equation A = 49 pennants

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of pennants required be represented as A

The amount of fabric bought by students = 28 yards

The amount of fabric required by each pennant = 1/3 yards

The total number of pennants made by students = 35 pennants

So , the number of pennants that can be made is N

N ( 1 / 3 ) = 28 be equation (1)

Multiply by 3 on both sides , we get

N = 84 pennants

So , the remaining number of pennants A = N - number of pennants made by students

On simplifying the equation , we get

The remaining number of pennants A = 84 - 45

The remaining number of pennants A = 49 pennants

Hence , the number of pennants is 49

The probability of senior taking the bus = 0.1 .

Probability is the study of likeliness of an event to occur. It has a range from 0 to 1. 0 means uncertainty and 1 indicates certainty.

It is given that

Sophomore , Junior and Senior probability table , if they drive to the school , Take the bus or walk.

It has been asked to determine the probability if senior take the bus

The favorable outcomes of this event is 5

The total outcome of this event is 5 + 20+25 = 50

The probability = Favorable Outcome / Total outcome

Probability = 5 / 50

P(Take the bus | Senior)  = 1/10 = 0.1

Therefore the probability of senior taking the bus = 0.1 .

BALTIMORE  It was not an overt incident of racism that prompted Edray Goins, an African-American mathematician in the prime of his career, to abandon his tenured position on the faculty of a major research university last year.

The hostilities he perceived were subtle, the signs of disrespect unsp_ken.

And at the recent math meeting, where Dr. Goins delivered a keynote address titled “A Dream Deferred: 50 Years of Bl_cks in Mathematics,” his presence kindled conversations about racial slights in the math world.

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.
