Answer:

it would be (-5,6)

Josh wants to add a model of a tree to his model railroad layout. How big should the model tree be if the actual tree is 315 inches and the scale is 1:90?

Answer:

4.5 inches

Step-by-step explanation:

The scale factor is 1:20 which is 1/20, and the actual height is 90 inches.

First, write down the proportion:

1/20 = x/90

Multiply both sides by 90.

=> x = 90/20

=> x = 4.5in

Therefore, the height of the model is 4.5 inches.

Answer:

oopp

Step-by-step explanation:

Answer:

A proportional relationship is something like:

y = k*x

where k is the constant of proportionality.

Notice that in these relationships we will always have the pair (0, 0)

because if x = 0:

y = k*0 = 0

Then we always have x= 0, y = 0.

Notice that in the first two tables we have the points:

(2, 0) in the first one

(0, 1) in the second one.

then neither of these can be a proportional relationship.

The only option left is the third one.

To graph the relationship, we can just graph the four points in the table.

Then draw a line that passes through all the points, like in the image below.

And this line is written as:

y = 3*x

such that:

y(1) = 3*1 = 3 -----> (1, 3)

y(2) = 3*2 = 6 -----> (2, 6)

y(3) = 3*3 = 9 ------>  (3, 9)

Answer:

area = 164

Step-by-step explanation:

Divide the square into 2 pictures.

; Square 1 = 5×2 = 10

Square 2 = 14×11 (11 from 16-5 )

so, square 2 = 154

all of area = 154+10 = 164

I'm pretty sure it's y= 45+25x

Answer:

y=45 + 25x

Step-by-step explanation:

When a question is asking for an initial fee, they are basically saying that you must pay that flat amount in addition to the amount you would pay for x hours of work. Say you work 5 hours. You have to multiply the number of hours, or x, by 25, then add 45.

Answer:

Mean score of 90 students = 77.2

Step-by-step explanation:

Mean score of 50 students from school A = 75

Mean score of 40 students from school B = 80

We need to find mean score of the 90 students?

First we will find sum of scores of students from school A

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]

So, Sum of scores for School A = 3750

Now, we will find sum of scores of students from school B

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]

So, Sum of scores for School B = 3200

Now, We will find mean score of the 90 students?

Mean score of 90 students will be:

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]

So, mean score of 90 students = 77.2

Answer:

14x-2y

Step-by-step explanation:

just break down the expression by combining like terms and getting rid of the parenthesis like so:

2(x+y)+4(x+y)+8(x-y)

i multiplied the number in front of each parenthesis with both numbers inside

ex: 2(x+y)

2x+2y

result:

2x+2y+4x+4y+8x-8y

next:

14x-2y

Answer:

14x -2y

Step-by-step explanation:

2( x + y ) + 4( x + y ) + 8( x - y )

First, do the distributive property ( multiply what is in the parenthesis by what is out of it)

2( x + y ) + 4( x + y ) + 8( x - y )

2 * x + 2 * y + 4( x + y ) + 8( x - y )

2x + 2y + 4( x + y ) + 8( x - y )

2x + 2y + 4 * x + 4 * y + 8( x - y )

2x + 2y + 4x + 4y + 8( x - y )

2x + 2y + 4x + 4y +  8 * x + 8 * -y

2x + 2y + 4x + 4y + 8x - 8y

Now combine like terms

14x -2y

And you cannot simplify it anymore

y=2x+9

Step-by-step explanation:

Slope intercept form is y=mx+b

m is the slope  (2)

b is the y-intercept  (9)

Plug the slope and intercept you were given in and you get the equation of the line in slope intercept form

y=2x+9

Question is incomplete :

The speed, S, of a bicycle varies directly with the number of revolutions per minute, R, that the pedals turn and the number of teeth on the front gear, F, and inversely with the number of teeth on the back gear B.

Lars is racing at 24 miles per hour. His front gear has 52 teeth and a back gear has 14 teeth. He is pedaling 84 revolutions per minute. As he sprints for the finish line, he pedals 112 revolutions per minute. What is his speed?

Answer:

32 mph

Step-by-step explanation:

Speed α number of revolutions α number of teeth on front gear α 1/teeth on back gear

Speed = S ; number of revolutions = R ; Number of teeth on front gear = F ; Number of teeth in back gear = B

S = k(R * F) / B

k = proportionality constant ;

24 = k(84 * 52) / 14

24 * 14 = 4368k

k = 336/4368

k = 0.0769230

Speed at R = 112

S = k(R * F) / B

S = 0.0769230(112 * 52) / 14

S = 447.999552 / 14

S = 31.999968

S = 32 mph

Answer:

201.1 radians per minute

Step-by-step explanation:

The formula for Angular speed of tires in radians per minute =

1 revolutions per minute = 2π rad/min

32 revolutions per minute = x

x = 32 revolutions per minutes × 2 π radians per minute

x = 201.06192983 radians per minute

Approximately

x = 201.1 radians per minute

Therefore, the angular speed of the tires in radians per minute is 201.1 radians per minute

The angular speed of the tires in radians per minute is 201 rad per minute.

Angular speed is the rate at which an object changes it angles, it is measured in radians in a given time.

To convert from rad per minute to rev per minute, we divide by 2π.

1 rad per min = 1/2π rev per min

32 revolutions per minute = (32 * 2π) radians per minute = 201 rad per minute.

The angular speed of the tires in radians per minute is 201 rad per minute.
