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.

Which expression is equilvalent to 2(x+y)+4(x+y)+8(x-y)?
Answers
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

If 8x−5y=−3 is a true equation, what would be the value of 8x−5y+7?
Answers
Answer:
Value of 8x -5y + 7 is 4.
Step-by-step explanation:
Given that:
8x-5y = -3 Eqn 1
It is a true equation.
Now we have to find the value of the given expression
8x -5y + 7
Putting value of 8x-5y from Eqn 1 in the given expression
8x - 5y + 7
-3 + 7
4
Therefore,
8x - 5y + 7 = 4
Hence,
Value of 8x -5y + 7 is 4.

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.
C 17. At high school A, the mean score of 50 students on a science test is 75.
At high school B, the mean score of 40 students on the same test is 80.
What is the mean score of the 90 students?
Answers
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

PLEASE HELP ILL MARK BRAINLY One of the tables shows a proportional relationship.
Graph the line representing the proportional relationship from this table.
Answers
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)

Find the value of F, correct to two decimal places
Answers
Answer:
F = 12.14 m
Step-by-step explanation:
F is the side opposite the given 36° angle and the given side length, 15m is adjacent. It's a cosine equation that's needed.
find the cosine of 36°
(calculator necessary)
cos(36) = 0.8090169944
We should be safe to round that to .809 for this.
cos = opp/adj
Substitute what we know:
.809 = F/15 Multiply both sides by 15
.809(15) = F
12.135 = F Round to two places.
Side F is 12.14m
