To rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]
Given the surd function:
[tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex]Rationalizing surd functions means multiplying the numerator and denominator of such function by the conjugate of the denominator.For the surd function given, to rationalize it, we only need to multiply the numerator and denominator by √11 as shown:
[tex]=\frac{2\sqrt{10} }{3\sqrt{11} }\times \frac{\sqrt{11} }{\sqrt{11} } \\=\frac{2\sqrt{110}}{3(11)}\\= \frac{2\sqrt{110}}{33}\\[/tex]
Hence we can conclude that to rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]

What is the area of the figure?
An irregular shape that is made of two rectangles end to end that are eight inches long each and four inches wide. The total length of the base is sixteen inches. With two right triangles on top of the rectangles so the right angles meet the sides of the rectangles. The total length of each side with the width of the rectangle and the side of the triangle is seven inches.
A. 88 square inches
B. 96 square inches
C. 120 square inches
D. 80 square inches
Answer:
d
Step-by-step explanation:
:)
PLS HELP ME WOULD REALLY appreciate It!!!
Answer:
C. Acute and Isosceles
Step-by-step explanation:
Acute means the angles are less than 90 degrees. All of the triangles angles are less than 90 degrees.
Isosceles means they have 2 sides of equal length. In the triangle, there are 2 sides with the length of 6 in, making this an isosceles triangle

What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?
Question 16 options:
A)
ƒ(11) = –31
B)
ƒ(11) = 32
C)
ƒ(11) = 23
D)
ƒ(11) = –22
Answer:
B. F(11) = 32
Step-by-step explanation:
From the explicit equation,
F(n) = 2 + 3(n - 1)
F(11) = 2 + 3(11 - 1)
F(11) = 2 + 33 - 3
F(11) = 35 - 3
F(11) = 32
The 11th term of the sequence with an explicit rule is 32

Sorry if I'm wrong...
And if I'm wrong, my second option would be C. $0.82
Solve the equation.
51 – 2z - 8z = 23
Answer: z=2.8
This is how I do!
Step-by-step explanation:
51-2z-8z=23
We simplify the equation to the form, which is simple to understand
51-2z-8z=23
We move all terms containing z to the left and all other terms to the right.
-2z-8z=+23-51
We simplify left and right side of the equation.
-10z=-28
We divide both sides of the equation by -10 to get z.
z=2.8
Answer:
Z=2.8
Step-by-step explanation:
51-10z=28
(/10) =2.8

1.Joe claims the measure of angle 3 is equal to 90 degrees.Is he correct?why or why not
2.state the measure of angle 5 and how you know
Thank you!
Answer:
1. No, Joe is not correct
2. [tex]\angle 5=72^{\circ}[/tex]
Step-by-step explanation:
Given: b and c are parallel lines
To find:
1. whether the given statement is correct or not
2. [tex]\angle 5[/tex]
Solution:
1.
Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]
[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)
[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]
So, Joe is not correct
2.
If two lines are parallel then alternate interior angles are equal.
As b and c are parallel lines,
[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)
Find the mean absolute deviation (MAD) of the data in the dot plot below.
Answer: The MAD is 1.6
Step-by-step explanation:To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Solve: -2 < x + 3 < 5
Answer:
The answer is
[tex] - 5 < x < 2[/tex]
Step-by-step explanation:
First you have to seperate them :
[tex] - 2 < x + 3[/tex]
[tex]x + 3 < 5[/tex]
Next you can solve it by moving all the unrelated terms to the other side :
[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]
[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]
Answer:
-5 < x < 2
Step-by-step explanation:
Subtract 3 from each of the three sides.
-2 < x + 3 < 5
-2 - 3 < x + 3 - 3 < 5 - 3
-5 < x < 2

Answer:
25) x = 18 26) x = 50
Step-by-step explanation:
25) 108 + 4x = 180
108 + 4x = 180
-108 -108
4x = 72
x = 18
26)
101 + (x + 29) = 180
101 + 29 + x = 180
130 + x = 180
-130 -130
x = 50

What is the percent of change in the cost of a DVD set that originally sold for$69.99 and is now on sale for $44.99? Round your answer to the nearest whole number.
Answer: 36%; yes, the % change is equal to the percent discount
Step-by-step explanation:
Initial price = $69.99
Final price = $44.99
change in price = |(final - initial)|
change in price = |(44.99 - 69.99)|
change in price = $25
25/69.99 = x/100
100(25/69.99) = x
100(0.357) = x
35.7% = x
x = 36%

PLS HELP I NEED IT RN WILL MARK THE BRAINLIEST PLSLSPSophie invests a total of $4500 in two separate accounts. One account pays 4% interest per year and the other one pays 4.75% per year. If the total interest earned at the end of one year is $202.50, how much money did she invest in each account?
Answer:
4% account - $1500
4.75% account - $3000
Step-by-step explanation:
x = amount of money in the account that pays 4% interest
y = amount of money in the account that pays 4.75% interest
x + y = 4500
0.04x + 0.0475y = 202.50
4x + 4y = 18000
4x + 4.75y = 20250
4x + 4y = 18000
- (4x + 4.75y = 20250)
= -0.75y = -2250
y = 3000
x + 3000 = 4500
x = 1500
