Answer:

-2/3

Step-by-step explanation:

You are looking the change in y over  the change in x.

for y, if you go from -5 to -7, how much did it change?  -2

-7 -(-5) = -7 + 5 = -2

Now look the the x's.  If you from 6 to 9 how much did you change?

3

9-6 = 3

-2/3

Answer:

-2/3

Step-by-step explanation:

A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]

Answer:

The change in altitude per minute is 63.5 alt/ min

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

In 24 minutes = 1524 feet

So, the average Change in altitude per minute

=1524/24

= 63.5 alt/ min

hence, change in altitude per minute is 63.5 alt/ min.

Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

[tex]\displaystyle{2x+8=62}[/tex]

Step 4: Subtract both sides by 8

[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]

Step 5: Divide both sides by 2

[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]

Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Step-by-step explanation:

The options 1,2 and 5 are the correct answer.

The given equation is 1.23/[tex]10^1[/tex]=0.123.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/[tex]10^1[/tex]=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

3) 12.3/[tex]10^0[/tex]=1.23

⇒ 12.3/1=12.3

So, LHS≠RHS

4) 0.123/10=1.23

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Therefore, the options 1,2 and 5 are the correct answer.

Answer:

y=4x

Step-by-step explanation:

if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4

Answer:

The slope is 4.

Step-by-step explanation:

Step 1:

Slope can also be found by using the formula, Y2-Y1/X2-X1

In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.

So, we can make the solution, -4-0/-1-0.

You can simplify this into, -4/-1, and then into 4.

Therefore, the slope is 4.

Step 2:

M is our slope, so in our y=mx equation our m = 4.

If you substitute in the m, you get y=4x.

Answer:

y=4x.

Answer:

*name* is 10 years old now and brother is 15 years now

In 10 years they would be 20 and 25 respectively

Step-by-step explanation:

Let x = *name*'s age now

let y = brother's age now

The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3

That means x/y = 2/3

Cross multiply => 3x = 2y =>

3x - 2y = 0   [1]

10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5

So (x + 10)/(y+10 = 4/5

Cross-multiply

5(x + 10) = 4(y + 10)

5x + 50 = 4y + 40

Subtract 4y from both sides

5x + 50 -4y = 40

and subtract 50 from both sides:

5x - 4y = 40 - 50

5x -4y = -10  [2]

Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that

[1] x 2

=> 2(3x - 2y) = 2 x 0

=> 6x - 4y = 0  [3]

[3] - [2]

6x - 4y - (5x -4y) = 0 - (-10)

6x - 4y -5x + 4y = 10

x = 10

Using equation [1] we get

x/y = 2/3

=> 10/y = 2/3

10 x 3/2 = y

5 x 3 = y

y = 15

So their ages are 10 and 15 now.

In 10 years they would be 20 and 25

If the ratios change we would have a different set of equations to solve for

For example if the current ratio is 1/3

Then we would get x/y = 1/3

or 3x - y = 0  [4]

and if 10 years from now the ratio is 3/5 then

(x + 10)/(y + 10) = 3/5

=> 5(x+10) = 3(y + 10)

=> 5x + 50 = 3y + 30

=> 5x - 3y = -20  [5]

And we would solve these equations to get x and y in a similar mannter

FYI the answers would be
x = 5, y = 15

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

First, you need to make the divisor a whole number, and then you make the dividend a whole number.

1.) 0.0056 divided by 0.004 = (0.0056 x 1000) x (0.004 x 1000)

You should make it a whole number by multiplying it by a power of ten.

2.) *5.6 divided by 4

Then divide.

3.) Answer : 0.0056 divided by 0.004 = 1.4

Answer: the answer is 14

Step-by-step explanation:0.056/- 0.004 as a percent value (as a percentage)

Detailed calculations below

Fractions: brief introduction

A fraction consists of two numbers and the fraction bar:

0.056/- 0.004

The number above the fraction bar is the numerator: 0.056

The number under the fraction bar is the denominator: - 0.004

To get the fraction's value, divide the numerator by the denominator:

The value = 0.056 ÷ - 0.004

Percent, p%: short introduction

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

How to convert a fraction to a percentage:

1) Calculate the value of the fraction.

2) Multiply this number by 100.

3) Add the percent sign %

Convert the fraction to a percentage

1. Calculate the value of the fraction.

To get the fraction's value, divide the numerator by the denominator:

0.056/- 0.004 =

0.056 ÷ - 0.004 =

- 14

A quick note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100

... and its value doesn't change.

n × 100/100 = n × 1 = n, any number n

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

(1,10) is the glide reflection of point A(-5,-4).

Answer:

On blueprint , length of room  is given by  feet and width is given by 10 feet.

Step-by-step explanation:

Given:  On a blueprint, the scale indicates that 6 cm represent 15 feet.

We have to find the value of  the length of a room that is 9 cm long and 4 cm wide on the blueprint.

Since, the scale indicates that 6 cm represent 15 feet

That is 6 cm = 15 feet

1cm =  feet

Thus, the scaling factor for 1 cm is  feet.

Thus, for length of a room  is 9 cm long.

On blueprint , length is given by  feet.

Also, given width of room is 4 cm

On blueprint , width is given by  feet.

Step-by-step explanation:

Answer: so it would be the length is 27.2 feet  and it is 8.88888889 feet wide or 8.9 ft wide and 27.2 feet long when its rounded i do hope i helped you and im so sorry if i didn't 27.2 goes in the box

Answer: it helps by making the question 10 times easier

Step-by-step explanation: because 4 and 6 both have the variable X they are like terms and can be added to each other unlike 30 it doesn’t have a variable meaning 4x or 6x cannot combine with 30 because it doesn’t have the variable X. Moving on 4x+6x is 10x as you add the number but X stays the same and so 10x=30 so you divided both sides by 10 because inverse operations and you get x=3 then after you import that into the question 4(3)+6(3)=30 which is the same as 12+18=30 which is true 30=30
