Find the value of x
Answer:8
Step-by-step explanation:
Because Angle GJH is 90 degrees, Angle HJZ is also 90 degrees. (Because all right angles are 90 degrees)
Now, find Angle WJZ
90 - 18 = 72 degrees
By the Vertical Angles Theorem, Angle GJL is congruent to Angle ZJW
Now solve for x
72 = 9x
x = 8

The ratio of domestic cars to imported cars in the lot at Al’s Auto Shop is 3 : 2. There are 42 domestic cars in the shop. How many cars are there altogether?
There are 70 cars altogether in the lot.
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of domestic cars to imported cars = 3 : 2,
Domestic cars = 42
Since, the number of domestic cars in the shop is 42,
Therefore,
3x = 42
x = 14
Therefore, the number of total cars = 14×5 = 70
Hence, there are 70 cars altogether in the lot.

In ΔEFG, e = 310 inches, m m∠G=89° and m m∠E=27°. Find the length of f, to the nearest 10th of an inch.
The length of f to the nearest 10th of an inch is 308.8 inches.
What is law of sines?A trigonometric rule known as the Law of Sines connects any triangle's sides and angles. It claims that for all three sides of a triangle, the ratio of the length of one side to the sine of the angle opposite that side is the same. To put it another way, we may write: If we have a triangle with sides a, b, and c, and opposing angles A, B, and C:
Sin(A) / a = b / a sin(B) / c / sin (C)
Using the Law of Sines we have:
f / sin(89°) = e / sin(27°)
f = sin(89°) * 310 / sin(27°)
f ≈ 308.8 inches
Hence, the length of f to the nearest 10th of an inch is 308.8 inches.

Answer:
613.7 in
Step-by-step explanation:
You want the length of side f in ∆EFG with e = 310 in, E = 27°, G = 89°.
Law of sinesThe law of sines tells you ...
f/sin(F) = e/sin(E)
Angle F is the third angle in the triangle, so its measure is ...
F = 180° - 89° -27° = 64°
Then the length of f is ...
f = e·sin(F)/sin(E) = (310 in)·sin(64°)/sin(27°) ≈ 613.7 in
The length of f is about 613.7 inches.

four times the sum of the three consecutive even intergers is 240 more than six times the smallest integer.
Answer:
Step-by-step explanation:
Let's call the smallest of the three consecutive even integers "x". Since they are consecutive and even, we know that the next two integers must be "x + 2" and "x + 4".
Now we can set up the equation for the problem:
4 * (x + (x + 2) + (x + 4)) = 240 + 6x
Expanding the parentheses on the left side:
4 * (3x + 6) = 240 + 6x
Simplifying the left side:
12x + 24 = 240 + 6x
Subtracting 6x from both sides:
6x + 24 = 240
Subtracting 24 from both sides:
6x = 216
Dividing both sides by 6:
x = 36
So the smallest of the three consecutive even integers is 36, and the others are 38 and 40.

Blake needs a wooden dowel that is 2 1/6 feet long. Blake needs to cut off 7.4167 feet from the dowel.
What are arithmatic operations?
Arithmetic operations is a branch of mathematics, that involves the study of numbers, the operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication, and Division.
To find out how much Blake should cut off the dowel, we need to subtract the length of the dowel from the required length.
The length of the dowel is -5 1/4 feet, which can be written as -5.25 feet.
The required length is 2 1/6 feet, which can be written as 2.1667 feet (rounded to four decimal places).
To find out how much needs to be cut off, we can subtract the length of the dowel from the required length:
2.1667 ft - (-5.25 ft) = 7.4167 ft
Therefore, Blake needs to cut off 7.4167 feet from the dowel.

Hint: Frequency Tables
The frequency table is completed and the percent of the people who have exactly one sibling is 20.48%.
What is Relative Frequency and Cumulative Frequency?Relative frequency is found by dividing the frequency with the total number of values.
Cumulative frequency is calculated by adding the previous frequencies together.
(a) From the table,
Total number of people = 210
So, Total frequency = 210
Frequency of number of siblings as 4 = 210 - (43 + 43 + 41 + 43) = 40
Relative frequency = Frequency / Total frequency
Relative frequency of number of siblings as 2 = 0.1952
Cumulative frequency of number of siblings as 3 = 127 + 43 = 170
(b) Percent of people having exactly 1 sibling = (43 / 210) × 100
= 20.48%
Hence the percent of people having exactly 1 sibling is 20.48%.

Which equation represents a nonlinear function?
Answer:
A nonlinear function is a function in which the rate of change of the output (y) is not proportional to the rate of change of the input (x). In other words, a nonlinear function is a function where the graph of the function is not a straight line.
Here are a few examples of equations that represent nonlinear functions:
y = x^2: This is the equation for a parabolic function, which is a classic example of a nonlinear function.
y = sin(x): This is the equation for the sine function, which is periodic and nonlinear.
y = |x|: This is the equation for the absolute value function, which is nonlinear and has a "kink" at x = 0.
y = log(x): This is the equation for the natural logarithmic function, which is also nonlinear.
These are just a few examples of nonlinear functions. There are many other types of nonlinear functions, including polynomial, exponential, and trigonometric functions.

If n is an integer and n > 1, then n! is the product of n and every other positive integer that is less than n. For example, 5! =5 • 4 • 3 • 2 • 1.
a. Write 6! in standard factored form.
b. Write 20! in standard factored form.
c. Without computing the value of (20!)2 determine how many zeros are at the end of this number when it is written in decimal form. Justify your answer.
a) Standard factored form is 2^4 × 3^2 × 5.
b) Standard factored form is 2^18 × 5^8.
c) There are 6 zeros at the end of (20!)^2
If n is an integer and n > 1, then factorial of n is the product of n and every other positive integer that is less than n.
We have to find the standard factor form of 6!
6! = 6 × 5 × 4 × 3 × 2 × 1
Then, we can simplify by grouping the factors of 6! into pairs that multiply to 10:
6! = 2 × 3 × 2 × 2 × 5 × 1 × 3 × 2 × 1 = 2^4 × 3^2 × 5
Therefore, 6! in standard factored form is 2^4 × 3^2 × 5.
Part b
To write 20! in standard factored form, we start with 20 and multiply by every positive integer less than 20:
20! = 20 × 19 × 18 × ... × 3 × 2 × 1
To simplify this expression, we can group the factors into pairs that multiply to 10
20! = (2 × 10) × (2 × 9) × (2 × 8) × ... × (2 × 1) × (5 × 3) × (5 × 2) × 5
We can then combine the factors of 2 and the factors of 5:
20! = 2^18 × 5^8
Therefore, 20! in standard factored form is 2^18 × 5^8.
Part C
The number of zeros at the end of (20!)^2 in decimal form is equal to the number of factors of 10 in (20!)^2. Since 10 = 2 × 5, we need to count the number of factors of 2 and 5 in (20!)^2.
The number of factors of 2 in (20!)^2 is the number of even integers less than or equal to 20, which is 10.
The number of factors of 5 in (20!)^2 is the number of multiples of 5 less than or equal to 20, which is
5, 10, 15, and 20.
However, since we are squaring (20!), we also need to count the number of factors of 25, which is 2:
5^2 and 10^2.
There are 6 zeros at the end of (20!)^2 when it is written in decimal form.
Therefore, each part has been solved

Amelia wanted to redeem a voucher. She had only 3/5of the total number
of points needed. After she earned another 50 points, she still needed 3/10
of the total number of points. How many points were needed to
redeem the voucher?
Answer:
The number of points needed to redeem the voucher is 92.5
Step-by-step explanation:
Let x be the total number of points needed to redeem the voucher.
Amelia has [tex]\frac{3}{5}[/tex] × x points,before she earns the another 50 points,
After she earns another 50 points,
Now
she has [tex]\frac{3}{5}[/tex] × x + 50 points.
she still needs [tex]\frac{3}{10}[/tex] × x points to redeem the voucher.
Now
From above we get a equation,
[tex]\frac{3}{5}[/tex] × x + 50 = [tex]\frac{9}{10}[/tex] × x
Solving the equation we can get x,
[tex]\frac{3}{5}[/tex] × x = [tex]\frac{9}{10}[/tex] × x - 50
if we multiply both sides by 5/3, we get,
x = (9/10 × x - 50) × 5/3
After expanding the right side,
x = (9/10 × x - 50) × 5/3
x = (9x/10 - 250/3)
Now,
Subtracting 9x/10 from both sides,
0 = 250/3 - 9x/10
If we add 9x/10 to both sides,
9x/10 = 250/3
Again,
If we multiply both sides by 10/9,
x = 250/3× 10/9
x = 250 × 10 / (3 × 9)
x = 250 × 10 / 27
x = 250 × 10 / 27
x = 250 × 10 / 27
x = 250 × 10 / 27
= 250 × .37
x = 92.5
The number of points needed to redeem the voucher is 92.5
In how many ways 4-digits numbers can be formed using the digits 1,2,3,7,8,9 without repetition? How many of these are even numbers?How many of these are even numbers?
We can form 15 different 4-digit numbers using the digits 1, 2, 3, 7, 8, and 9, without repetition. Out of these, 30 are even numbers. We used the concept of combination to find these numbers.
Combination is a mathematical technique used to calculate the number of ways in which a group of objects can be selected from a larger set, without considering their order.
We can use the combination formula to find the total number of possible combinations:
C(4, 3) = 4! / (3! * 1!) = 4
This means that we can form four different 3-digit numbers using the digits 1, 2, 3, and 4, without repetition.
Now, coming back to our original problem, we need to form 4-digit numbers using the digits 1, 2, 3, 7, 8, and 9, without repetition. Using the same combination formula, we can find the total number of possible combinations:
C(6, 4) = 6! / (4! * 2!) = 15
This means that we can form a total of 15 different 4-digit numbers using the given digits.
Next, we need to find out how many of these numbers are even. An even number is a number that is divisible by 2, and in our case, this means that the last digit of the number must be either 2, 8, or a combination of 1 and 7.
To find the number of even 4-digit numbers, we can use the same combination formula, but this time we have to consider only 3 digits (2, 8, and a combination of 1 and 7) for the last digit:
C(3, 1) * C(5, 3) = 3 * 10 = 30
This means that we can form a total of 30 different 4-digit even numbers using the given digits.

What is slope-intercept form?
The graph of the equation y = mx + b is represented by a line with a slope of m and a y-intercept of b. The slope-intercept representation of the linear equation is employed, and the values of m and b are real numbers.
We are given two options.
Using slope-intercept form, we get the equations as
Option 1
It requires monthly fee of $7.50 which means this is the y-intercept and $3.50 per game which means this is the slope.
So, the equation is y = 3.5x + 7.5
Option 2
Slope = (33 - 16.5)/ (6 - 3)
Slope = 16.5/ 3
Slope = 5.5
The y-intercept for this is 0.
So, we get the equation as y = 5.5x.

HelpThe ratio of the perimeters of two similar quadrilaterals is 2:4. What is the ratio of their areas? PLLLLLLLLLLSSSSSSss
a.1:2
b. 4.8
c. 2:4
d. 4:16
e. 5:3
The ratio of the areas of the quadrilaterals is 1:2. Option A
What is the ratio of the perimeter?Let's assume that the two similar quadrilaterals have side lengths of x and 2x, respectively. The ratio of their perimeters is then 2x + 2x + 2x + 2x = 8x : 2 * (2x + 2x + 2x + 2x) = 4 * 8x = 32x. The ratio of the perimeters is 2:4, so we can write the equation:
8x/32x = 2/4
Solving for x, we find that x = 4.
So the ratio of the areas of the two similar quadrilaterals is (x^2)/(2x)^2 = (4^2)/(2 * 4^2) = 16/32 = 1/2.
Therefore, the ratio of the areas of the two similar quadrilaterals is 1:2.
