Answer:

Martin climbs at a rate of 20 meters per hour

Step-by-step explanation:

Martin and Alexia are rock climbing. Each person's rate stays the same for the first hour they climb.

For Martin's,

Distance = [tex]3\dfrac{1}{3}\ m=\dfrac{10}{3}\ m[/tex] in 1/6 hour

Rate is given by :

[tex]R=\dfrac{\frac{10}{3}}{\frac{1}{6}}\ m/h\\\\=\dfrac{10}{3}\times 6\\\\=20\ \text{meters/hour}[/tex]

For Alexia,

Distance = [tex]17\dfrac{1}{2}\ m=\dfrac{35}{2}\ m[/tex] in 5/6 hour

Rate is given by :

[tex]R=\dfrac{\frac{35}{2}}{\frac{5}{6}}\ m/h\\\\=\dfrac{35}{2}\times \dfrac{6}{5}\\\\=21\ \text{meters/hour}[/tex]

Hence, the correct option is (A) "Martin climbs at a rate of 20 meters per hour"

Answer:

A. 10+10+5x=80 or 20+5x=80

B. Disagree, After the pay for each person to get in the have 60 dollars left. Each ride costs 5 dollars. 60 divided by 5=12 and each of them would need a ticket, so they could only ride 6 rides/

C. 20/5=4=they could by an additional 4 tickets, each would need a ticket so they could ride 2 more rides each

Step-by-step explanation:

80-20=60

60/5=12

Answer:

Below are the answers

Step-by-step explanation:

Part A: The equation would be 5x - 20 = 80

Part B: I disagree, because each ride is $5 and if they both go on 12 that would host $120 and they only have $60 to spend. Since we took away $20 for tickets.

Part C: If Mia adds $20 dollars it would look like this 5x - 20 + 20 = 80 or

5x = 80 They would be able to go on 4 more additional rides. Because the original equation they can only go on 12 rides now they can go on 16 rides.

For a quadratic equation, we start out seeking 2 solutions.

According to the statement

We have to find about the quadratic equation.

So, For this purpose, we know that the

Quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power

From the given information:

when we solve a quadratic equation, how many solutions should we always start out seeking.

Then

Here, we are required to search out out what number solutions to start out out seeking while solving a equation and also the condition for a quadratic graph not having zeros ( no x-intercepts).

Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.

And, a quadratic can haven't any zeros ( no x intercepts) if the roots of the equation are complex numbers.

A quadratic is one which has the very best degree of its variable ( usually x) to be 2.

Consequently, after we solve a quadratic, one should start out seeking two (2) solutions.

This is so because, the quantity of solutions to begin out seeking corresponds with the very best power of the experimental variable, X.

Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.

Therefore, where X¹ occurs in an equation, it's linear and consequently has 1 solution.

And, where X² occurs in an equation, it's quadratic and consequently has 2 solutions.

It is possible to possess a quadratic with no zeros (i.e no x-intercepts).

So, For a quadratic equation, we start out seeking 2 solutions.

Nobody representing a legitimate scholarship can or will be able to guarantee that you’ll win. Some services even boast they can guarantee the actions of another organization – they can’t. There are false promises and will likely result in something other than you obtaining money for school.

The equation that can be used to represent these two elevations as solutions will be 29028 - (-1312).

From the information, highest natural point in the world is Mt. Everest with an elevation of 29,028 feet above sea level andd the lowest natural point in the world is the Dead Sea, which sits at 1,312 feet below sea level.

Therefore, the equation which depict the two elevations will be the difference between the elevations and this will be:

= 29028 - (-1312)

= 30340

The distance between them is 30340 feet.

Answer: x = -7

Step-by-step explanation:

4(1 - x) + 2x = -3(x + 1)

First, use distributive property

4 - 4x + 2x = -3x + -3

Combine like terms

4 - 2x = -3x - 3

Add 3x to each side

4 + x = -3

Subtract 4 from each side

x = -7

Answer:

-2

1. Equation at the end of step 1  ((4•(1-x))+3x)-(0-2•(x-1))  = 0

Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90°.  The length of the longest side of the triangle is not known.

How many different triangles can be drawn with these dimensions? Explain your reasoning.

Step-by-step explanation:your weclome

The number of triangles that can be drawn with these dimensions will be one.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one point of 90° The length of the longest side of the triangle isn't known.

The longest side of the triangle is given as,

H² = P² + B²

H² = 12² + 5²

H² = 144 + 25

H² = 169

H = 13 cm

If the three dimensions of the triangle are known, then the number of possible triangles is only one.

The number of triangles that can be drawn with these dimensions will be one.

1. Pizza

A pizza is a circle and the area of a circle increases with the square of the radius.

A= pi r^2

you have 10pi inches in small pizza and the area is 100pi

20 pi inches in larger pizza and area is 400pi

So the area larger pizza is 5 times the area small pizza.

2. problem 5

1. Scale Up (smaller to larger)= larger figure measurement / small figure measurement.

scale up = 16/8 = 2.

the scale factor is 2.

When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles

2. the area of original = 1/2 bh= 1//2 x 8 x 6 = 24

3. the area of enlarged =  24 x 2= 48.

4. Yes. To enlarge a triangle with sloping sides, it is easiest to enlarge the base and the height. The base is 2 squares long and the height is 3 squares long. Multiply these lengths by the scale factor of 2 to find the enlarged shape.

**Polygon

explain: The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.

use the figure below and you find the polygon.

Rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]

Step-by-step explanation:

We need to rearrange the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject.

[tex]x=\frac{2w+1}{5-3w}\\x(5-3w)=2w+1\\5x-3wx=2w+1\\[/tex]

Subtract 2w on both sides

[tex]5x-3wx-2w=2w+1=2w\\5x-3wx-2w=1\\[/tex]

Subtract 5x on both sides

[tex]5x-3wx-2w-5x=1-5x\\-3wx-2w=1-5x\\[/tex]

Taking w common on left hand side

[tex]w(-3x-2)=1-5x\\[/tex]

Divide both sides by -3x-2

[tex]\frac{w(-3x-2)}{-3x-2} =\frac{1-5x}{-3x-2}\\w=\frac{1-5x}{-3x-2}[/tex]

So, rearranging the expression [tex]x=\frac{2w+1}{5-3w}[/tex] to make w the subject we get [tex]\mathbf{w=\frac{1-5x}{-3x-2} }[/tex]
