To get rid of a radical we multiply the radical by itself, so we multiply [tex]\frac{3}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}[/tex]
to get [tex]\frac{3\sqrt{2}}{2}[/tex].
#3:
[tex]\sqrt\frac{2}{5}[/tex] is the same as [tex]\frac{\sqrt{2}}{\sqrt{5}}[/tex] so we multiply by [tex]\frac{\sqrt{5}}{\sqrt{5}}[/tex] so we get [tex]\frac{\sqrt{10}}{5}[/tex].
#4:
We combine like terms to get [tex]-2\sqrt{2} + 4\sqrt{3}[/tex]
Hope this helps!

What is the value of x?
Answers
Answer:
135°
Step-by-step explanation:
here's your solution
=> we know that , sum of all angles is
equal to 180°
=> hence ,we have two angles
=> 1st angle = 45°
=> 2nd angle = 9x + 18
=>. adding both angle
=> 45° + 9x + 18° = 180°
=> 63° + 9x = 180°
=> 9x = 180° - 63
=> 9x = 117°
=>. x = 117/9
=> x = 13°
=>. hence, the required angle = (13*7) + 18°
=> angle = 135°

Jamal spent _ 3 4 of his allowance. On the number line, label the fraction that represents the part that Jamal spent. Explain
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Fraction of pocket money spent by Jamal = 3/4
The number line is divided into 4 equal parts with distance between successive tick marks representing 1 of the whole = (1/4). Hence, 3/4 of the whole would mean 3 portions of the total 4 portions of the number line represents the amount spent by Jamal.
The fraction spent by Jamal is also labeled on the number line picture in the attached document.
Find the distance d between 21 = (-7 - 6i) and Z2 = (-15 – 12i). Express your answer in exact terms and simplify, if needed.
Answers
Answer:
10
Step-by-step explanation:
The distance is equal to the modulus of Z1-Z2.
[tex]Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10[/tex]

The common prime factor of the numbers 77 and 242? will be 11.
What is a prime factor?A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,
Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,
77 / 11 = 7
242 / 11 = 22
Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

sin 0 = 24/25
cos 0 = 7/25
tan 0 = 24/7
Step-by-step explanation:
hey there!
sine = opposite divided by hypotenuse
the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25
cosine = adjacent divided by hypotenuse
the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25
Tangent.= opposite divided by adjacent
the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7

Ralph’s annual expenses for the upcoming year are summarized in the chart below. Based on the information in the graph, approximately what percent of his total annual income is Ralph having withheld for taxes?
a. 6%
b. 18%
c. 30%
d. 36%
Answers
Answer:
D
Step-by-step explanation:
You have to do the summation of all expenses so
1,750+3,260+3,500+4,332+6,652+4,880+15,000+3,448+18,380= 61,202
The total of taxes is composed of state taxes and federal taxes
3,448+18,380= 21,828
Set up a proportion to calculate the percentage
21,828 : 61,202 = x% : 100%
[tex]x\% = \frac{21828 \times 100}{61202} = \frac{2182100}{61202} = 35.67\%[/tex]
You can approximate the result to 36%
The percentage of the annual budget withheld for taxes is 36%.
Total budget of RalphThe total budget of Ralph is calculated as follows;
T = 1,750 + 3,260 + 3,500 + 4,332 + 6,652 + 4,880 + 15,000 + 3,448 + 18,380
T = $61,202
Total tax on Ralph's annual budgetTax = 3,448 + 18,380
Tax = $21,828
The percentage of the annual budget withheld for taxes is calculated as follows;
[tex]= \frac{tax}{total \ budget} \times 100\%\\\\= \frac{21,828}{61,202} \times 100\%\\\\= 35.67 \ \%\\\\\approx 36 \ \%[/tex]
