Answer:
The length of the rectangle is 6 ft while the width is 3 ft.
Step-by-step explanation:
The formula for finding the area of a rectangle is
<em> </em><em> </em><em> </em><em> </em><em>area = width x </em><em>length</em><em> </em> and vice versa
lets substitute the numbers that we already know
18 = <em>w</em> x <em> </em><em> </em><em>2w</em>
We know from our times tables that 2 times 9 equals 18, and also that 3 times 6 equals 18.
6 is two times 3, so that works out!! Lets give it a try
18 = 3 x 3(2)
18 = 3 x 6
18 = 18 !!!
and we are done!

1.
List the scores:
(2) 60
(1) 65
(5) 75
(1) 95
(1) 100
Find the chart with those quantities: Chart A
2. Find the mean:
75 + 60 + 75 + 100 + 75 + 75 + 75 + 95 + 60 + 65 = 755
755/10 = 75.5
Subtract the mean from Ashley’s score:
60 – 75.5 = -15.5
The answer is D.
Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:
![3x - 11 = 2x + 11](https://tex.z-dn.net/?f=3x%20-%2011%20%3D%202x%20%2B%2011)
Solving:
subtract 2x from both sides
![x-11=11](https://tex.z-dn.net/?f=x-11%3D11)
add 11 to both sides
![x = 22](https://tex.z-dn.net/?f=x%20%3D%2022)
Next, find the angle measures of the two base angles:
![3*22-11\\66-11\\55](https://tex.z-dn.net/?f=3%2A22-11%5C%5C66-11%5C%5C55)
To find y, you know that the interior angles of the whole triangle add up to 180, so you have
![55 + 55 + 2y = 180](https://tex.z-dn.net/?f=55%20%2B%2055%20%2B%202y%20%3D%20180)
solving,
![110 + 2y = 180](https://tex.z-dn.net/?f=110%20%2B%202y%20%3D%20180)
subtract 110 from both sides
![2y = 70](https://tex.z-dn.net/?f=2y%20%3D%2070)
divide both sides by 2
![y = 35](https://tex.z-dn.net/?f=y%20%3D%2035)
Answer:
Domain: All Real Numbers Range: All Real Numbers
Step-by-step explanation:
The function x + y = 10 is a linear function. Its graph is a line on the coordinate plane. As such the line extends both left and right and up and down without any restrictions. This means there are no limits on its domain or range. Both are all real numbers.
