A rectangular poster is 2/3 meter long and 1/2 meter wide. What is the area of the poster in fraction form
Answer:
1/3
Step-by-step explanation:
Easy! What is -6^2? The calculator says -36, but -6*-6 is 36. Confusing.
You entered;
[tex]-6^{2}=(-1)(6)(6)=(-1)(36)=-36[/tex]
In order to get the answer that you intended;
[tex](-6)^{2}=(-6)(-6)=36[/tex]

an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Answer:
45
Step-by-step explanation:
This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.
(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)
Hope this helps!
One angle of a triangle measures 75. The other two angles are in a ratio of 5:16. What are the measures of those two angles?
Answer:
25 and 80
Step-by-step explanation:
180 - 75 = 105
105 / (5+16) = 5
multiply each side of the ratio 5:16 by 5
5x5 : 16x5 = 25:80

The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.
Answer:
Length = 18 meters
Step-by-step explanation:
Let the length of the rectangular pool = l meters
And breadth of the pool = w meters
Perimeter of the rectangular pool = 2(l + 2w)
Since, perimeter of the rectangular pool is 72 meters.
2(l + 2w) = 72
l + 2w = 36 --------(1)
If length of the pool is twice of its breadth,
l = 2w
w = [tex]\frac{l}{2}[/tex] -------(2)
By substituting the value of 'w' from equation (2) to equation (1),
[tex]l+2\times{\frac{l}{2}}=36[/tex]
2l = 36
l = 18 meters

Explain the three different types of solutions you can get when solving a system of
equations.
Answer:
There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution.
Step-by-step explanation:
9514 1404 393
Answer:
no solutionsa finite non-zero number of solutionsinfinite solutionsStep-by-step explanation:
1. No Solutions
This case arises when the equations are inconsistent. No values of the variables can satisfy all of the equations. An example is ...
y = xy = x+1__
2. Finite Number of Solutions
The number of distinct solutions depends on the degree of the system and the domain being considered. For example, an n-th degree polynomial equation in one variable will always have n solutions in the domain of complex numbers. However, it may or may not have any real-number solutions. (The question here has no context, so we have to assume it is about any system of equations of any degree or nature (rational, polynomial, exponential, mixed, or other.))
__
3. Infinite solutions
An under-specified system, such as a system of 3 equations in 4 variables, may have an infinite number of solutions. In such a system, one or more of the variables may be allowed to assume any value. Systems that have dependent equations will fall into this category.

Explain how to use the distributive property to simplify: -2(x + 5) ?
Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
[tex]\huge\bold{ANSWER:}[/tex]
-2x-10
[tex]\bf{EXPLANATION:[/tex]
Hi there!
Here's what the Distributive Property states:
a(b+c)=ab+ac
So, we take a number outside the parentheses, and "distribute" it.
In this case, we should distribute -2:
-2(x+5)
-2x-10 (a negative times a negative is a positive)
Hope it helps!
Enjoy your day!

Helppp. Write an equation to solve for a. Then find the missing angle.
Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a

Answer:
Step-by-step explanation:
answer no 3:
1] Factor out the common term 2.
2(3x+y) = -26
2] Divide both sides by 2.
3x+y= -26/2
3x+y = − 13
3]Subtract y from both sides.
3x = - 13-y
4] Divide both sides by 3.
x = -13-y/3
Part 2:-
Add 6y to both sides.
x=21+6y
x=21+6y

A child building a tower with Blocks uses 15 for the bottom row. Each row has 2 fewer blocks than the previous row. What formula would you use to find the number of blocks in the 5th row?
A)blocks in 5th row =15+(15-1)-2
B)blocks in 5th row=15+(5-1)(-2)
C)blocks in 5th row=15+(5+1)(-2)
D)blocks in 5th row=5+(15-1)(-2)
Answer:
B)blocks in 5th row=15+(5-1)(-2)
Step-by-step explanation:
We are given that
Number of block in bottom row=15
Each row has 2 fewer blocks than the previous row
We have to find the formula would you use to find the number of blocks in the 5th row.
Number of blocks in second row=15-2=[tex]15+1(-2)[/tex]
Number of blocks in third row=15-2-2=[tex]15+2(-2)[/tex]
Number of blocks in 4th row=[tex]15-2-2-2=15+3(-2)[/tex]
Number of blocks in 5th row=[tex]15-2-2-2-2=15+4(-2)[/tex]
Therefore, number of block in 5th row
[tex]15+(5-1)(-2)[/tex]
This is required formula to find the number of blocks in the 5th row
Hence, option B is true.
B)blocks in 5th row=15+(5-1)(-2)

whats the answer to
-7y=7x+21
Answer:
y = -x - 3
x = -y - 3
Step-by-step explanation:
If solving for y,
-7y = 7x + 21
-y = -x + 3 (dividing everything by 7)
y = -x - 3
If solving for x,
-7y = 7x + 21
-y = -x + 3
x = -y - 3

The angular speed for a Wind turbine with blades turning at a rate of 19 revolutions per minute is
Answer
The answer to the question is 3.157 revolutions per second.
Step-by-step explanation:
The reason is because speed is the distance the object travels in a second.
So, we know that the wind turbine is moving 19 revolutions per minute, so therefore to find the number of rotations the wind turbine is doing per second we have to do 60/19 because there is 60 seconds in a minute.
Therefore, if we do that equation we get the answer, as 3.157 revolutions per second!
