The absolute value of -183 is _______.
Answer:
183
Step-by-step explanation:
The absolute value of a number is the number's distance from zero, which will always be a positive value. To find the absolute value of a number, drop the negative sign if there is one to make the number positive.
Answer: 183 ✅
Step-by-step explanation:
Hii, do you need to know the absolute value of "-183"? No problem! (:
What is Absolute Value? | DefinitionThe absolute value of a number is that number's distance from zero.

angle A and angle B are a linear pair. If measure of angle A = 4x-10 and measure of angle B = 3x+43, find the measure of angle A and measure of angle B
Answer:
See below ~
Step-by-step explanation:
Linear pairs add up to 180 degrees.
⇒ 4x - 10 + 3x + 43 = 180
⇒ 7x + 33 = 180
⇒ 7x = 147
⇒ x = 21
∠A = 4(21) - 10
∠A = 84 - 10
∠A = 74°
∠B = 3(21) + 43
∠B = 63 + 43
∠B = 106°

2(xy-7)=-20 with x=-1 y=3
Step-by-step explanation:
2(xy-7)=?
When variables are connected such as xy, this means to multiply.
x=-1
y=3
Multiply the x and the y together.
-1*3=-3. Plug that into the equation.
2(-3-7)=?
Subtract the inside the parenthesis.
2(-10)=?
Multiply. Remember when multiplying a positive and a negative the answer will always be a negative.
2(-10)=-20
This means that 2(xy-7)=-20 with the x=-1 and y=3.
Hope this helps!

if you are examining a triangle with given measurements for one leg and the hypotnuse,how will you determine the measure of the unknown leg?
We will apply the Pythagoras theorem to find the measure of the unknown leg in a triangle when one leg and the hypotenuse are provided dimensions.
What is the definition of a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.
According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.
[tex]\rm h^2 = p^2+ b^2[/tex]
Where,
h is the hypotenuse
p is the perpendicular
b is the base
If any of the two is given the third side will be obtained using the Pythagoras theorem.
In a triangle with given measurements for one leg and the hypotenuse, we will determine the measure of the unknown leg by the Pythagoras theorem.
Hence we willl apply the pythogorous theorem for finding the unknown side.

Group A shows 1 dot at 9, 7 dots at 10, 8 dots at 15, 8 dots at 17, and 6 dots at 19. Group B shows 6 dots at 10, 5 dots at 14, 6 dots at 18, 5 dots at 25, 4 dots at 28, and 4 dots at 29.
Based on visual inspection, which group most likely has a lower mean age of painting students? Explain your answer using two or three sentences. Make sure to use facts to support your answer.
Answer:
The group that is most likely able to have a lower mean age of painting students is Group A
Step-by-step explanation:
mean = sum of all terms divided by total number of terms
Looking at the graph data you have provided you can see that group A's students are a younger than students in Group B.
Which means when you calculate the mean the group which would give you the lower ratio with the same denominator of K (let there is K number of students in the class) will have lower mean age
here group A students are younger therefore their ratio will be lower
hence lower mean age

Use the periodic compound interest formula to solve.
Suppose that $11,000 is invested at 5.8% compounded quarterly. Find the total amount of this investment after 6 years.
Answer:
$15,539.67
Step-by-step explanation:
Compound Interest Formula
[tex]\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}[/tex]
where:
A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = $11,000r = 5.8% = 0.058n = 4 (quarterly)t = 6 yearsSubstitute the given values into the formula and solve for A:
[tex]\implies \sf A=11000\left(1+\frac{0.058}{4}\right)^{(4 \times 6)}[/tex]

The equation -x = y + 7 written in slope-intercept form is
Answer:
y= -x-7
Step-by-step explanation:
Slope intercept form: y = mx + b
m = slope
b = y intercept
The first thing you must do is isolate y so that it is by itself on the left side of the equation:
-x = y + 7
Subtract 7 to both sides:
-x - 7 = y + 7 - 7
-x - 7 = y
Flip:
y = -x - 7
-x = y + 7 in slope intercept form is y = -x - 7
This means the slope is -1 and the y-intercept of the equation is (0, -7)

A locker combination consists of two nonzero digits, and each combination consists of different digits. Event A is defined as choosing an odd number as the first digit, and event B is defined as choosing an odd number as the second digit.
If a combination is picked at random, with each possible locker combination being equally likely, what is P(A and B) expressed in simplest form?
A. 5/18
B. 4/9
C. 1/2
D. 5/9
The correct answer is option B which is P ( A|B) will be ( 4 / 9 ).
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:-
A locker combination consists of two nonzero digits, and each combination consists of different digits. Event A is defined as choosing an odd number as the first digit, and event B is defined as choosing an odd number as the second digit.The total sample will have 9 numbers
S = { 1,2,3,4,5,6,7,8,9} = 9
Even Number = { 2,4,6,8} = 4
Odd Number = { 1,3,5,7,9} = 5
P ( A ) = ( 4 / 9 )
P ( B ) = ( 5 / 9 )
The probability will be calculated as:-
P( A:B ) = [tex]\dfrac{P(A)\times P(B)}{P(B)}[/tex]
P( A:B ) =[tex]\dfrac{( 5/9 ) ( 4/9 )}{5 / 9 }[/tex]
P( A:B ) = 4 / 9

If the side length of a square is 4 inches, its area is
square inches and its perimeter is
inches.
The area of the square is 16 square inches and its perimeter is 16 inches.
What is Area of square ?
A square is a two-dimensional geometric shape with four equal sides and four right angles. The area of a square is the measure of the region enclosed by the square. The area is expressed in square units, such as square inches, square meters, or square feet.
The area of a square is given by the formula:
A = s²
where A is the area and s is the length of a side.
If the side length of the square is 4 inches, the area can be calculated as:
A = 4² = 16 square inches.
The perimeter of a square is given by the formula:
P = 4s
where P is the perimeter and s is the length of a side.
If the side length of the square is 4 inches, the perimeter can be calculated as:
P = 4 x 4 = 16 inches.
Therefore, the area of the square is 16 square inches and its perimeter is 16 inches.
