Answer:
I believe that it would be better to use the second scale, or 1ft to 500ft.
Step-by-step explanation:
If you used the first scale(1in to 10ft) then you would have a 75in model, or 6.25ft, this would be to big to display on your desk. If you used the second then your model would be about 1.5in which all though is small it would be better for display.
Answer:
1 inch
Step-by-step explanation:
1 foot = 500 feet
1 inch = 10 feet
^ if you do 12 x 10 it equals 120, which is less than 1 foot = 500.
But, if you want it a big it would be 1 foot = 500.
For what value or values of x = 7 < 3x + 2?
A. x = 5/3
B. x > 5/3
C. x < 5/3
D. x is ≥ 5/3
Solve this equation:
3 (5x + 2) - 7 (3x - 4) = (5 - 9x) 2
I need step by step explanation with details.
Thank you!
Answer:
x = - 2
Step-by-step explanation:
3(5x + 2) - 7(3x - 4) = (5 - 9x)2
15x + 6 - 21x + 28 = 10 - 18x
34 - 6x = 10x - 18
-12x = 24
x = -2

All the parts are solved below.
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the equations -
1. 2a=4.6
2. b+2=4.6
3. c÷2=4.6
4. d−2=4.6
5. e+38=2
6. 18f=3
7. g÷85=1
We have -
[1] -
2a = 4.6
a = 2.3
[2] -
b + 2 = 4.6
b = 2.6
[3] -
c ÷ 2 = 4.6
c x 1/2 = 4.6
c = 4.6 x 2
c = 9.2
[4] -
d − 2 = 4.6
d = 6.6
[5] -
e + 38 = 2
e = - 36
[6] -
18f = 3
f = 3/18
f = 1/6
[7] -
g ÷ 85 = 1
g x 1/85 = 1
g = 85
Therefore, all the parts are solved above.

SHOW ALL OF WORK. Find missing length, round to the nearest tenth if necessary.
Answer:
144 or 72^2
Step-by-step explanation:
You have one leg a 5 and the other leg we don't know, well we know the hyponuse is a 13.
So the first step is
A^2 + B^2 = C^2
2 step,
5^2 + B^2 = 13^2
3 step
5 x 5 = 25 and 13 x 13 = 169
25 + B^2 = 169
4 step
169 - 25 = 144
144 divided by 2 is 72, so 72 x 72 is 144.
If you have an answer 72 squared or 144 both will work.
It does not help that you don't give the answers.

What is the surface area of the figure?
9514 1404 393
Answer:
B. 24 cm²
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh
Here, you have a base of 4 cm and a height of 3 cm, so the area is ...
A = (1/2)(4 cm)(3 cm) = 6 cm²
__
The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...
A = WH
A = (4 cm)(4.5 cm) = 18 cm²
The total area is the sum of the areas of the parts:
total area = triangle area + rectangle area
total area = 6 cm² + 18 cm² = 24 cm²
