what is the value of x in the figure please help I’ll give you brainliest :)
Answer:
37°
Step-by-step explanation:
(4x + 2)° = 150° [Vertically Opposite Angles]
=> 4x = 150 - 2
=> 4x = 148
[tex] = > x = \frac{148}{4} [/tex]
=> x = 37° (Ans)
Angle (4x+2)° and angle 150° are vertically opposite angles so, their measures will be equal.
Which means :
[tex] =\tt 4x + 2 = 150[/tex]
[tex] =\tt 4x = 150 - 2[/tex]
[tex] = \tt4x = 148[/tex]
[tex] =\tt x = \frac{148}{4} [/tex]
[tex]\hookrightarrow \: \color{plum}x = 37[/tex]
Let us check whether or not we have found out the correct measure of x by placing 37 in the place of x:
[tex] =\tt 4 \times 37 + 2 = 150[/tex]
[tex] = \tt148 + 2 = 150[/tex]
[tex] =\tt 150 = 150[/tex]
Since the measures of both the angles are equal we can conclude that we have found out the correct value of x.
Thus, the value of x in this figure = 37
Therefore, the correct option is (A) 37.

Step-by-step explanation:
what is the first six terms of the sequence f(n)=(-3)^n
Answer:
The first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:
[tex]-3, 9, -27, 81, -243, 729[/tex]
Step-by-step explanation:
Given the sequence
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
Here [tex]n[/tex] represents any term number in the sequence
Determining the first term
substitute n = 1 in the sequence to determine the first term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]\:f\left(1\right)=\left(-3\right)^1[/tex]
[tex]f\left(1\right)=-3[/tex]
Thus, the first term is -3.
Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]\:f\left(2\right)=\left(-3\right)^2[/tex]
[tex]\:f\left(2\right)=9[/tex]
Thus, the 2nd term is 9.
Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(3\right)=\left(-3\right)^3[/tex]
[tex]f\left(3\right)=-27[/tex]
Thus, the 3rd term is -27.
Determining the 4th term
substitute n = 4 in the sequence to determine the 4th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(4\right)=\left(-3\right)^4[/tex]
[tex]f\left(4\right)=81[/tex]
Thus, the 4th term is 81.
Determining the 5th term
substitute n = 5 in the sequence to determine the 5th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(5\right)=\left(-3\right)^5[/tex]
[tex]f\left(5\right)=-243[/tex]
Thus, the 5th term is -243.
Determining the 6th term
substitute n = 6 in the sequence to determine the 6th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(6\right)=\left(-3\right)^6[/tex]
[tex]f\left(6\right)=729[/tex]
Thus, the 6th term is 729
Therefore, the first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:
[tex]-3, 9, -27, 81, -243, 729[/tex]

I have a calculator that can display ten digits. How many different ten-digit numbers can I type using just the 0-9 keys once each, and moving from one keypress to the next using the knight’s move in chess? (In chess, the knight move in an L-shape – one square up and two across, two squares down and one across, two squares up and one across, and other like combinations)
Answer:
It has to start on 5 and then go to 0, or else not all of the numbers will go in the knight move pattern.

The act of factoring is to reduce numbers down to their____.
The act of factoring is to reduce numbers down to their prime number.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
A prime number is a positive integer having exactly two factors that are 1 and the number itself. Any number that does not follow this is termed a composite number.
For example:
Let the number 2310, then the factor of the number 2310 will be
2310 = 2 × 3 × 5 × 7 × 11
Where, 2, 3, 5, 7, and 11 are the prime numbers.

what was the original weight of the ball ?
Answer:
16.5
Step-by-step explanation:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
but 16.5 is the answer

althea normally saves $x each month; but in june she saved $4 more than twice her usual amount. in june she saved...
Answer:
The amount saved in June is;
$(2x + 4)
Step-by-step explanation:
Here, we want to get the amount saved in June
From the question, she saved $5 more than twice here usual amount
twice here usual amount is 2 * x = $2x
So, adding the extra $4; the amount saved will be;
2x + 4
A swimming pool had 30 gallons of water in it. Then water was added to the pool at a rate of 5 gallons per second. The function y= 5t + 30 describes the relationship between the number of gallons, y, and the number of seconds water was added, t. Select all of the ordered pairs that correspond to input-output pairs for the function.
A. (45,3)
B. (3,45)
C. (0,30)
D. (30,0)
The (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given the function:
y = 5t +30,
Here y is the no of gallons and t is the time.
Take the values of option A and substitute in the function,
45 = 5 × 3 +30
45 = 45
Hence, it is the correct-ordered pair,
Similarly, take option b
3 = 45 × 5 +30
3 ≠ 255
Now take option c,
0 = 30 × 5 +30
0 ≠ 180
Take the last option,
30 = 0 × 5 +30
30 = 30
Hence, it is also the ordered pair.
Therefore, the (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.

[tex] {4}^{2} + {5}^{2} = {41}^{2} [/tex]
[tex] \sqrt{41} = 6.403124237[/tex]
An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).
Answer:
If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.

Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?
Step-by-step explanation:
formula to find area of a triangle:
A=1/2 × base × height(h)
insert the values into the formula:
24=1/2 × 4 × h
solve for h :
24=2h
24/2=h
h = 12 cm ( Ans )
The height of triangle will be 12 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle has a base length of 4 cm.
And, A total area of 24 cm².
Now,
We know that;
Area of right triangle = 1/2 × Base × Height
⇒ 24 = 1/2 × 4 × h
⇒ 24 = 2 × h
⇒ h = 24 / 2
⇒ h = 12 cm
Thus, The height of triangle = 12 cm.

60 packs x 12 pens = 720 pens
Step 2: Find out how much Charles spent
2.80 per pack
Charles bought 60 packs
60 x 2.80 = 168 pounds
Step 3: Find out how many pens Charles sold
Charles sold 2/3 of his pens
2/3 x 720 = 480
Step 4: Find out how manypens he sold
Charles sold the pens for 40p
40p x 480 = 19200p

=
e
=
Answer:
a = 84°
b = 36°
c = 24°
d = 84°
e = 132°
Step-by-step explanation:
The parameters of the workers in the office are;
The number of staffs in the office = 60 staffs
The take-aways are pizza, curry, fish & chips, kebab and other
The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively
The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively
In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;
∠a = 360° × 14/60 = 84°
∠b = 360° × 6/60 = 36°
∠c = 360° × 4/60 = 24°
∠d = 360° × 14/60 = 84°
∠e = 360° × 22/60 = 132°
