Find the length of side x in simplest radical form with a rational denominator.
Answer:
[tex] x = \frac{2*\sqrt{3}}{3} [/tex]
Step-by-step explanation:
Reference angle = 30°
Opposite side = x
Adjacent side = 2
Apply the tan trigonometric function, thus:
[tex] tan (30) = \frac{opp}{adj} [/tex]
[tex] tan (30) = \frac{x}{2} [/tex]
[tex] 2 * tan (30) = x [/tex]
[tex] 2 * \frac{1}{sqrt{3}} = x [/tex] (tan 30 = 1/√3)
[tex] \frac{2}{sqrt{3}} = x [/tex]
Rationalize
[tex] \frac{2* \sqrt{3}}{sqrt{3} * \sqrt{3}} = x [/tex]
[tex] \frac{2*\sqrt{3}}{3} = x [/tex]
Can only like terms be combined?
Answer:
yes
Step-by-step explanation:
only like terms can be combined
Answer:
yes. If it's variables, then only like variables can be combined. If it's fractions, then they must be converted to a common denominator before combining.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
As per the given,
4 copies of 1/5
The first copy of /5 = 1/5
Second one = 1/5
Third = 1/5
And fourth = 1/5
Collective all copies are 1/5 + 1/5 + 1/5 + 1/5
Take LCM as 5,
(1 + 1 + 1 + 1)/5 = 4/5
Hence "The 4 copies of the fraction 1/5 will be 4/5".

pls solve this i cannot do it find x y z in the above
Answer:
x = 115
z= 40
y = 140
Step-by-step explanation:
x = 180 - (40 +25) = 115
z = 180 - (115+25) = 40
y = 180 - (40) = 140

The required value of unknown number a would be 2000.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
WE need to determine 55% of what number is 1100.
Let the unknown number is a. then we get;
55% of a = 1100
55/100 of a = 1100
55/100 x a = 1100
Cross mulitiplication, we get;
55a = 1100 x 100
55a = 110000
Divide by 55, we have;
a = 110000/ 55
a = 10000/ 5
a = 2000
Therefore, the required value of unknown number a would be 2000.

For what value of the constant c is the function f continuous on
(−∞,∞) where
f(b) = { cb + 9 if b ≤ 3
c(b)² − 9 if b > 3
9514 1404 393
Answer:
c = 3
Step-by-step explanation:
In order for the function to be continuous at b=3, the left and right limits must be the same. In short, we must have ...
c(3) +9 = c(3²) -9
18 = 6c . . . . . . . . add 9-3c to both sides
3 = c . . . . . . . . . . divide by 6
Function f is continuous when c=3.

Which equation represents the line that has a slope of 4 and passes through the points (2,7)
Answer:
The answer is y = 4x - 1.
Step-by-step explanation:
The answer is y = 4x - 1.
Step-by-step explanation:
☆The equation we'll be using: y = mx + b
☆Since we already have the slope. we have to find the y-intercept.
☆\begin{gathered}y = mx + b \\ \\ 7 = 4(2) + b \\ 7 = 8 + b \\ \frac{ - 8 = - 8 \: \: \: \: \: \: \: \: \: \: \: }{ - 1 = b \: \: \: \: \: \: \: \: \: \: } \end{gathered}
y=mx+b
7=4(2)+b
7=8+b
−1=b

The coordinates of the vertexes of a triangle are A(3,3) B(6,6) C(9,3). What will be the new coordinates after a dilation
with a scale factor of 3 if you use the origin as the center of dilation?
0)
A)
A (9,9) B'(18,18) C'(27,9)
B)
A'(0,0) B'(3,3) C (6,0)
A'(1,1) B'(2.2) C'(3,1)
D)
A'(6,6) B'(9.9) C'(12,6)
Answer:
A
Step-by-step explanation:
Dilation by 3 from origin causes each point to be multiplied by 3.
(3,3) * 3 = (9, 9)
(6, 6) * 3 = (18, 18)
(9, 3) * 3 = (27, 9)
which is A
Question 2 1 pts Asplaner has three sections colored green, purple, and pink. If the spinner is spun three times, how many possible outcomes are there!
Answer:
27
Step-by-step explanation:
The Counting Principle states that the number of possible outcomes is equal to the product of the number of outcomes for each event. In this case, (M)(N)(O).
There are 27 possible outcome if the spinner is spun three times.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, A spinner has three sections colored green, purple, and pink.
From the general formula of probability:
Probability = (desired outcomes)/(Total outcomes)
In our case,
the three possible outcomes of this event occurring are Green, Purple, and Purple, Green.
The desired outcomes = 3
The total outcomes = 3 x 3 x 3 = 27

Help please. 4. Solve for x.
Please answer and explain I’ll mark brainliest!!!!!
Answer:
See below
Step-by-step explanation:
Problem 1
If n is the smallest of the consecutive integers, the next integer would be n+1.
Problem 2
The equation is terms of n is going to be
s = n + n + 1 + n + 2 + n+3
Problem 3
Collect like terms on the right
s = 4n + 6
Problem 4
4n + 6 = s Subtract 6 from both sides
4n = s - 6 Divide by 4
n = (s - 6)/4
Problem 5
Solve for n when s = 2174
n = (2174 - 6)/4
n = 2168 / 4
n = 542
check
n = 542
n + 1 = 543
n + 2 = 544
n + 3 = 545
Total 2174 Just as it should

Answer:
27.50
Step-by-step explanation:
Since it is 16.50 each and they bought 5 packets total an easy way to solve this problem would be that you multiply 16.50 × 5 which will give you how much the total cost of the candy would be:
16.50 × 5 = 82.50
Since that is the total amount you would then divide 82.50 by 3 since Mary and her friends all split the cost three ways (since there are three of them):
82.50 ÷ 3 = 27.50
Which will give you your answer.
