That is, if you exclude 0. If you count zero as a positive number, that will be the exception to the rule. Luckily, zero is usually considered neither negative or positive.

The area of square C is 100 square units and the area of square B is 64 square units. What would be the area of square A?
Answer: The area of square A is 28 square units because the area is decreasing by 36 and the angles on each side is decreasing by 9
Step-by-step explanation:
100 divide by 4 sides = 25
64 divide by 4 sides = 16
28 divide by 4 sides = 7

Answer:
m=s+0.50
3m+2s=23.95
Step-by-step explanation:
Answer:
m-s+0.50
3m+2s=23.95
Step-by-step explanation:
the first one is defining m in terms of S
the second is solving
I know they didn't ask but here is the solution:
so in this case you would replace 3m with 3(s+0.50)

find exact value for f(x)=sin^-1(-1/2)
Answer:
The exact value
[tex]sin^{-1} (\frac{-1}{2} ) = \frac{7\pi }{6}[/tex] = 210°
Step-by-step explanation:
Step(i):-
Given that the inverse trigonometry
[tex]sin^{-1} (\frac{-1}{2} )[/tex]
We know that the sine function has negative in third quadrant
[tex]sin^{-1} (\frac{-1}{2} ) = sin^{-1} ( sin (\pi +\frac{\pi }{6} )[/tex]
We have to use trigonometric formula
[tex]sin^{-1} ( sin (x)) = x[/tex]
Step(ii):-
[tex]sin^{-1} (\frac{-1}{2} ) = sin^{-1} ( sin (\pi +\frac{\pi }{6} ) = \pi +\frac{\pi }{6}[/tex]
= [tex]\frac{6\pi +\pi }{6} = \frac{7\pi }{6}[/tex]
Final answer:-
The exact value
[tex]sin^{-1} (\frac{-1}{2} ) = \frac{7\pi }{6}[/tex]

Use the Distributive Property to solve the equation.
- 4(x + 2) = 24
Apply the Distributive Property and simplify.
- 4(x + 2) = 24
- 4x + _ = 24
What goes in between -4x+ and =24
Answer:
-8
Step-by-step explanation:
First multiple the x by -4 giving -4x then multiply the same -4 by 2 giving -8
Sam has already worked for 27.7 hours this week. He washes cars, and can wash a car in 2.5 hours. He wants to work over 60.2 hours this week.
The question is incomplete ; we could calculate the least number of cars he can still wash for the week expressed in inequality form.
Answer:
x > 13 ; 13
Step-by-step explanation:
Given that :
Anticipated work hour for entire week = 60.2 hours
Hours worked = 27.7 hours
Rate of car wash = 2.5 per hour
Hours left to work for the week :
60.2 - 27.7 = 32.5
Hours left / unit rate of car wash
32.5 / 2.5
= 13
Hours worked +( hours left * unit rate) > anticipated hours
27.7 + 2.5x < 60.2
2.5x > 60.2 - 27.7
2.5x > 32.5
x > 32.5 / 2.5
x > 13
Hence ; Sam could still wash over 13 cars this week

How many calendars did the 1st and 2nd period classes sell on average per week? Write and solve a multiplication equation.
Answer:
About 27 calendars per week
Step-by-step explanation:
I dived 60 by 7 because there are 7 days in and week and got 8.5 which I round up by 9. I did the same with 123 and got 17.5 which I round up to 18. By adding them together, they sell 27 averagely per week.
Hope this Helped
The average number of calendars sold in the 1st and 2nd periods is 91.5.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Number of calendars sold in 1st period = 60
Number of calendars sold in 2nd period = 123
The average of calendars sold in the 1st and 2nd periods.
= (60 + 123) / 2
= 183/2
= 91.5
Thus,
The average number of calendars sold is 91.5.

the quiz. Which best describes the percent of increase in his score.
Answer:
His quiz score increased by about 7%.
Step-by-step explanation:
Take the two quiz scores and add them together to get 159.
Take the difference between the two quiz scores to get 11.
Divide the difference by the sum to get 0.0692 or about 7%.
The ratio of the energy of a photon of x-rays of wavelength 0.05 nm to that of a photon of visible light of wavelength 500 nm is
Answer:
1 : 10000
Step-by-step explanation:
Energy of a photon of x-rays of wavelength = 0.05 nm
Energy of a photon of visible light of wavelength = 500 nm
The ratio is given as;
0.05 : 500
1 : 10000
Therefore, ratio of the energy of a photon of x-rays of wavelength to that of a photon of visible light of wavelength is 1 : 10000

Part A: Create at a system of liner equations with no solutions. In two or more complete sentences explain the specific characteristics that you have include in each equation to ensure that the system would not have a solution.
Part B: Using one of the equations that you created in part A create a system of liner equations that has one solution (x y)use substitution to solve the system.
A system of linear equations with no solution means that the lines never meet. So as long as your two lines have the same slope and different intercepts, they will be parallel.
Ex.) y= 2x + 5
and y=2x + 10
to have a solution, the lines have to cross at a point. so literally any two lines that aren't parallel.
Ex.) y= 3x + 1
to find the solution you start by setting the equations equal to each other
2x + 5 = 3x + 1
1) subtract 2x from both sides
5= x + 1
2) subtract 1 from both sides
4 = x
now we know the x value of the point is 4. To find the y value plug 4 into one of the equations
2(4) + 5
8 + 5
13
so the solution to this particular system is (4,13)
An isosceles triangle has an angle that measures 120°. Which other angles could be in that isosceles triangle? Choose all that apply.
Answer:
they will be both 30°.
Step-by-step explanation:
in an isosceles triangle measure of two angles are same
if one angle of an isosceles triangle is 120°
and the other two angles are equal then
take the equal angles be x
so,
x + x + 120° = 180°2x = 180° - 120°x = 60° / 2x = 30°9 3/4 divided by 3 1/4
