Answer:
(W2-1)xW
Step-by-step explanation:
The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!
Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.
Area = 2y^2-y
Given data
Let the Length of the rectangle be x
and let the width be y
From the statement "The length of a rectangle is 1 less than twice the width"
the length can we re-written as
x = 2y-1
We know that the area of a rectangle is
Area = Length*Width
Area = (2y-1 )* y
Area = 2y^2-y
hence the expression for the area is given as 2y^2-y

NEED HELPPP
Answer:
A. 11/36
Step-by-step explanation:
Add all the numbers together(36), and then see how many out of that number are the vibrant blue shirt. Since they are asking the probability of you being given a vibrant blue shirt, and there are 11 out of the 36 shirts, therefore you have an 11/36 chance that you will be given a vibrant blue shirt.
Answer:
11/36
Step-by-step explanation:
36 is the total amount of t-shirts and 11 t-shirts are vibrant blue.
In the system 4x + 9y = 7 and and 4x - 9y = 9, would I add or subtract this system to solve for x? To solve for y?
add to solve for x or add to solve for y
subtract to solve for x or subtract to solve for y
add to solve for x and subtract to solve for y
subtract to solve for x and add to solve for y
Answer:
add to solve for x and subtract to solve for y
Step-by-step explanation:
To solve for any variable, it is required to eliminate the other variable in two variable - two equation set.
The set of equations are
4x + 9y = 7 __________1
4x - 9y = 9 ___________2
To solve for x we need to eliminate Y
We see that in equation 1 there is 9y and
in equation 2 there is -9y
if we add 9y and -9y (9y -9y = 0)
Hence it is clear that to solve for x , it is needed to add equation 1 and equation 2.
by adding equation 1 + equation 2 we have
4x + 9y = 7 __________1
=> 4x - 9y = 9 ___________2
=>4x + 9y + 4x -9y = 7 +9
=>8x = 16
=>x = 16/8 = 2
____________________________
To solve for y we need to eliminate x
We see that in equation 1 there is 4x and
in equation 2 also there is 4x
if we subtract 4x and 4x (4x -4x= 0) , we get 0
Hence it is clear that to solve for y , it is needed to subtract equation 2 from equation 1.
by performing equation 1 - equation 2 we have
4x + 9y = 7 __________1
=> 4x - 9y = 9 ___________2
=>4x + 9y -( 4x -9y) = 7 - 9
=>4x + 9y - 4x +9y = -2
=>18y = -2
=>y = -2/18 = -1/9
_____________________________
Thus, correct answer is
add to solve for x and subtract to solve for y
Answer: The answer is add to solve for x and subtract to solve for y, I hoped this helps, brainliest please? :)

Jackson gave Lena this expression to evaluate: 14(8 + 12). Lena said that to evaluate the expression was simple; just multiply the factors 14 and 20. Jackson told Lena she was wrong. He solved it by finding the product of 14 and 8 and then adding that to the product of 14 and 12.
a. Evaluate the expression using each student’s method.
b. Who was right in this discussion? Why?
Answer:
In this discussion, they both got the same answer, so they're both right. However, when Jackson said Lena was wrong, he was incorrect, because Lena's way was also correct. So, they were both right in this discussion when it comes to the answers, but Jackson was wrong when he said lena was wrong. (I hope this helped).
Step-by-step explanation:
Lena: 14(8 + 12)
14(20)
280
Jackson: 14 x 8 = 112
14 x 12 = 168
168 + 112 = 280

What is the volume of the cylinder? Express the answer in terms of Pi.
A cylinder with a diameter of 8 centimeters and height of 18 centimeters.
Recall the formula V = pi r squared h.
288 pi Centimeters cubed
1,152 pi Centimeters cubed
1,296 pi Centimeters cubed
2,592 pi Centimeters cubed
Answer:
288 pi Centimeters cubed
Step-by-step explanation:
To find the volume of the cylinder with diameter of 8 centimeters and height of 18 centimeters, we will follow the steps below:
First, write the formula for calculating the volume of a cylinder
volume of a cylinder = πr²h
where r is the radius and h is the height of the cylinder
from the question given, height h = 18 cm and diameter = 8 cm
but diameter = 2r, this implies that r=[tex]\frac{d}{2}[/tex] hence radius r = [tex]\frac{8}{2}[/tex] = 4 cm
we can now proceed to insert the values into the formula;
volume of a cylinder = πr²h
=π×4² ×18
=π×16 ×18
=288 π cm³
volume of the cylinder = 288 π cm³
Answer:
its A

This sculpture is made of solid onyx and has a square hole through the middle. How much onyx was used to make the sculpture?
The volume of the sculpture is in.3.
To find the volume of the onyx used, we have to find the volume of the larger figure and then subtract the volume of the smaller figure from it.
The volume of onyx used is equal to 128in^3
Volume of the larger figureLet's proceed to multiply through the length, width and height of the figure to determine the volume.
[tex]volume = length * width * height \\volume = 8 * 8 * 3\\volume = 192in^3[/tex]
The volume of the larger figure is 192in^3
Let's calculate the volume of the square hole
[tex]volume of square = (length)^3\\volume of the square = 4^3 \\volume of the square = 64in^3[/tex]
Data;
Volume of larger figure = 192in^3volume of the square hole = 64in^3Let's subtract now and calculate the volume of onyx used
[tex]volume of onyx used = 192 - 64 = 128in^3[/tex]
The volume of onyx used is equal to 128in^3

The height of a flare fired from a 32-foot high platform can be modeled by the function h= -16t^2 + 16t + 32, where h is the height in feet above the ground and t is the time in seconds. Find the time it takes the flare to reach the ground
Answer:
Time, t = 2 seconds
Step-by-step explanation:
The height of a flare fired from a 32-foot high platform can be modeled by the function :
[tex]h= -16t^2 + 16t + 32[/tex]
Here, h is the height in feet above the ground and t is the time in seconds.
It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,
h = 0
[tex]-16t^2 + 16t + 32=0\\\\t=\dfrac{-16+\sqrt{16^2-4\times (-16)(32)} }{2(-16)}, \dfrac{-16-\sqrt{16^2-4\times (-16)(32)} }{2(-16)}\\\\t=-1\ s, 2\ s[/tex]
Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.

For the given angle measure, find the measure of a supplementary angle and the measure of a complementary angle, if possible. If not possible, type the word none in lowercase letters in the box.
The given angle measure is 27º
Answer:
A complementary angle is 63 degrees and supplementary angle is 153 degrees.
Step-by-step explanation:
Complementary angle:
A complementary angle adds up to 90 degrees, so you have to subtract 27 from 90. 90-27=63
Supplementary angle:
A supplementary angle adds up to 180 degrees, so you have to subtract 27 from 180. 180-27=153
Answer:
The supplementary angle is
153°.
The complementary angle is
63°.
