Answer:
The maximum number of rectangles that Mirela can cut is 5
Step-by-step explanation:
First, you must ensure that all the measurements are the same units.
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
where a, b and c are known values and x the value to calculate. So:
[tex]x=\frac{c* b}{a}[/tex]
The direct rule of three is the rule applied in this case where there is a change of units.
To perform this conversion of units, you must first know that 1 m² = 10,000 cm². So, if 10,000 cm² is 1 m², how many cm² equals 0.35 m²?
[tex]cm^{2} =\frac{0.35 m^{2} *10000 cm^{2} }{1 m^{2} }[/tex]
cm²= 3500
Now, to calculate the maximum number of rectangles that Mirela can cut you divide the total area of the paper by the area of each rectangle:
3500 cm² ÷ 700 cm²= 5
The maximum number of rectangles that Mirela can cut is 5

solve 7+x/3 = 2x-5
Answer:
x = [tex]\frac{22}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{7+x}{3}[/tex] = 2x - 5 ( multiply both sides by 3 to clear the fraction )
7 + x = 3(2x - 5) ← distribute
7 + x = 6x - 15 ( subtract x from both sides )
7 = 5x - 15 ( add 15 to both sides )
22 = 5x ( divide both sides by 5 )
[tex]\frac{22}{5}[/tex] = x ( x = 4.4 )
Maximum and Minimum Values of General Quadratic Functions
1. By expressing y = 2x^2 + 4x + 17 in the form y = a(x + b)^2 + C, where a, b, and c are constants, state the minimum value of y and the value of x at which this occurs. Hence, sketch the curve y = 2x^2 + 4x + 17
x =
y =
Answer:
x=-1
y=15
Step-by-step explanation:
This works because completing the square is essentially demonstrating what g(x) - where g(x) in this case = x^2 - would have to be translated by to give the function you have.
So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.
Which of the following is the equation of the graph below?
Answer:
I think it's the 3rd one
Step-by-step explanation:
Answer:
y=2x+1
Step-by-step explanation:
y intercept is one so it cannot be the last one and we see the slope is rise/run=2/1= 2
so equation is y=2x+1

Because the graph below is misleading, which magazine appears to have about four times the circulation of circuitry today?
a. American Ampersand
b. Waffle all World
c. Fossil Week
d. None of them
Answer:
A. American Ampersand
Step-by-step explanation:
Question is asking for what appears to be four times the circulation and American Ampersand appears to be four times the circulation.
Since the graph below is misleading, a magazine which appears to have about four times the circulation of circuitry today is: A. American Ampersand.
What is a graph?A graph can be defined as a type of chart that is typically used for the graphical representation of data such as magazine circulation in a country, by using both the horizontal and vertical lines, which are called x-axis and y-axis respectively.
By critically observing the misleading graph above, we can deduce that American Ampersand is a magazine which appears to have about four times the circulation of circuitry today because its bar is the smallest among others.

please help me !!!!!
Answer:
61 feet
Step-by-step explanation:
We can use the pythagorean theorem to solve this answer (a^2 + b ^2 = c^2, c= longest length)
50^2 + 35^2 = 61.03.
Rounded to the nearest whole number, the answer is D.
Answer:
C
Step-by-step explanation:
It's a right triangle so you can use a squared +b squared =c squared
a and b are the legs of the triangle which in this case are 50 and 25 feet.
Plug them into the equation:
50^2+25^2=c^2
50 squared = 2,500
25 squared = 625
2,500 + 625= 3,125
so c squared is 3,125. To get c you need the square root which is ~55 feet
4(3x – 1) – 2(6 + 2x)
Answer:
12x - 12
Step-by-step explanation:
4(3x)= 12x

Solve the following equation for x.
11x– 1 = -89
Answer:
x = -8
Step-by-step explanation:
11x– 1 = -89
Add 1 to each side
11x– 1+1 = -89+1
11x = -88
Divide each side by 11
11x/11 = -88/11
x = -8

Z-12=4
what is Z worth?
Answer:
Z=16
Step-by-step explanation:
just add 12 to both sides so you are left with only Z on one side
Answer:
=16
Step-by-step explanation:
Simplifying
z + -12 = 4
Reorder the terms:
-12 + z = 4
Solving
-12 + z = 4
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + 12 + z = 4 + 12
Combine like terms: -12 + 12 = 0
0 + z = 4 + 12
z = 4 + 12
Combine like terms: 4 + 12 = 16
z = 16
Simplifying
z = 16
SOLVE RIGHT NOW PLEASE. Determine the solution to the system of equations below by using the ELIMINATION METHOD.
6x+5y=39
3x+5y=27
Answer: x=4 and y=3
Step-by-step explanation:
We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.
The Twix factory is producing Left and Right Twix, wrapping them separately, and then packaging them into a variety of bags. Each bag contains 25 pieces of candy. The number of Right Twix is three more than the number of Left Twix.
Write a system of equations that represents the situation.
Then solve the system of equations, SHOWING ALL YOUR WORK.
Answer:
Candies
l = 25b r = b(25 + 3)
Example: b = 10 bags
l = 25 x 10 r = 10(25 + 3)
l = 250 candies r = 10 x 28 = 280 candies
Bags
r = l + 3
Examples: r = 15 bags l = 15 bags
15 = l + 3 r = 15 + 3
15 - 3 = l + 3 - 3 r = 18 bags
12 bags = l
i need to find the 9th term of this sequence
9514 1404 393
Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

Step-by-step explanation:
2f-1)^2
This is equal to
(2f-1) * (2f-1)
FOIL
first: 2f*2f = 4f^2
outer: 2f*-1 = -2f
inner: -1*2f = -2f
Last = -1*-1 = 1
Add them together: = 4f^2 -2f-2f+1
Combine like terms 4f^2 -4f+1
Answer:
(2f-1)(2f-1)
2f^2-2f-2f+1
