perimeter of a rectangle is 36 cm . If the length of the rectangle is 12 cm . Find its area.
Answer: 72 cm
Step-by-step explanation:
So since we know its length is 12 cm, that leaves us with finding the width. You could do that by adding the two length's together to get 24, then subtract that from the perimeter to get 12. The widths being added together must equal 12 and be the same, so we can divide by 2 to get 6 cm as the width. Then multiply 6 times 12 to get 72
Answer: A=72 cm²
Step-by-step explanation:
Let the width of the rectangle be x
Hence, P=36 cm l=12 cm
P=2(l+x)
P=2l+2x
P-2l=2x
Divide both parts of the equation by 2
Thus,
[tex]\displaystyle\\x=\frac{P-2l}{2} \\\\x=\frac{36-2(12)}{2}\\\\x=\frac{36-24}{2} \\\\x=\frac{12}{2} \\\\x=6 cm\\\\[/tex]
Area A=l*x
A=12*6
A=72 cm²

During a 90-minute school play, the main character was on stage 80% of the time.
What amount of time in minutes was the main character on stage?
88.9 minutes
112.5 minutes
80 minutes
72 minutes
Answer:
72 minutes
Step-by-step explanation:
you convert the 80% to decimal form so its now 0.80.
then you multiply how long the school play was (90) times the 'percentage' of how long the main character was on the stage (0.80).
90 times .80 is 72.

Find the values of X and Y. State which theorem(s) you used.
Using alternating and corresponding angle theorem, the value of x and y are (8, 146), (86, 94) and (21, 29.5) respectively
Alternate and Corresponding Angle TheoremAlternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent. Corresponding and Alternate angles are the most fundamental angles formed when two parallel lines are intersected by a transversal line.
5)
3x = 5x - 64
Reason: Alternate angles are equal
5x + 3x = 64
8x = 64
x = 8
y + 5x - 6 = 180
Reason: Angles on a straight line are equal to 180
y + 5(8) - 6 = 180
y + 40 - 6 = 180
y + 34 = 180
y = 146
6) x = 86
Reason: Alternating angles are equal to one another
y + 86 = 180
Reason = 94
7) 2y = 59
Reason: Vertical angles are equal
y = 59 / 2
y = 29.5
2y = 3x - 4
Reason: Alternate angles are equal
2(29.5) = 3x - 4
59 = 3x - 4

Write and solve the equation that represents the sentence below.
The product of 18 and a number is 109.8 .
Which statements are correct? Select three options.
The linear equation we want to write is:
18*x = 109
And the solution is x = 6.06
How to write and solve the equation?Remember that the product between two numbers is just a multiplication A*B.
Here we know that the product of 18 and a number, is 109.
If we define the variable x as the number, then we can write the linear equation:
18*x = 109
Where the product between 18 and x is equal to the number 109.
Now, we want to find the value of x, to do that, we need to divide both sides of the equation by 18, then we will get:
18*x/18 = 109/18
x = 109/18 = 6.06

Answer:
Step-by-step explanation:
The function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x
Transformation techniques
Transformation is the process of changing the position of an object on the xy-plane.
Given the parent function
f(x) = 4x
If the function is not reflected over x-axis, the resulting function will be f(x) = -4x
If the resulting function is compressed by a factors of 1/8, hence the final function rule will be;
g(x) = 1/8(-4x)
g(x) = -1/2x
Hence the function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

what is -57.17 as a mixed number
The value of 57.17 as a mixed number is - 57 17/100.
In simple terms, what is a mixed number?A mixed number is said to be in its simplest form if its fractional part's highest common factor, or HCF, is 1. When mixed numbers are simplified, the fraction value remains constant. We can say that the simplified mixed number and the actual mixed number are fractions that are equivalent.
A mixed number is made up of three components: a whole number, a numerator, and a denominator. The numerator and denominator are both components of the proper fraction that results in the mixed number.
In this case, -57.17 will be:
= -57 + (17/100)
= -57 17/100.

( Choose... ) What are the coordinates of Point P? ( Choose... ) Which point has coordinates ( 1 , 4 ) ? Choose... In order to create a rectangle using these points as three of the vertices, what coordinates should be used for the fourth vertex? ( Choose... )
The coordinates of the points of the rectangle are given as follows:
Point Z: (3,5).Point P: (6,2).Point T is the point that has coordinates given by (1,4).The coordinates of the fourth vertex are given as follows:
(4,1).
What are the coordinates?The notation of an ordered pair is given as follows:
(x-coordinate,y-coordinate).
Point T is plotted 1 unit right and 4 units up from the origin, hence the coordinate are:
(1,4).
Point P is is plotted 6 units right and 2 units up from the origin, hence the coordinates are:

arrangements can she make with those flowers so that, there is no flower left & what does they look
like.
Answer:
4
Step-by-step explanation:
Given: Number of roses = 8, Number of daisies =12 and number of marigolds 48.
Since we have given,
Number of roses = 8 , Number of daisies = 12 and number of marigolds = 48.
The factors of 8 = 2 * 2 * 2
The factors of 12 = 2 * 2 * 3
The factors of 48 = 2 * 2 * 2 * 2 * 3
Therefore, greatest common factor of 8, 12 and 48 is 4.
Therefore, the total number of arrangements = 4

A card is chosen at random from a standard
deck. What is the probability that the card is
a spade or a king, given that it is black?
the probability of getting a king or a spade is 30.7%.
What is probability?
Simply put, probability measures how probable something is to occur. The probability formula can be used to calculate the likelihood of an event by simply dividing the favorable number of possibilities by the total number of options. The likelihood of an occurrence might vary from 0 to 1 because the favourable number of outcomes can never be greater than all possible outcomes.
The formula for calculating the probability of an event is
Probability of an event = Favorable outcomes/Total number of outcomes.
Favorable outcomes = 16 {13 spade cards which include one king and the remaining 3 king cards.}
The total number of outcomes = 52.
Probability of choosing a king or a spade= 16/52 = 8/26 = 4/13=0.307
Hence, the probability of getting a king or a spade is 30.7%.

e) [0,1]
f) just the y-value: 5; as a point: (-8,5)
g) just the y-value: -5; as a point: (-4,-5)
Step-by-step explanation:
a) Domain is all of the x-values that are defined in the function. The smallest x-value in the graph is -9, and the largest is 8. And all values in between are defined (have corresponding y-values). But notice that there's an open dot on (8,0).
b) Range is found the same way as Domain, but with the y-values. The smallest y-value of this function is -5, and the largest is 5.
For c-e, notice where the graph changes direction and draw a vertical line from the x-axis through the turning point. These lines are the boundaries between intervals of increasing/decreasing/constant. You should have vertical lines at x=-4, x=0, x=1, and x=6.
c) Interval(s) on which f(x) is increasing: Reading the graph from Left To Right, between which vertical lines is the graph going up?
d) Interval(s) on which f(x) is decreasing: Reading the graph from Left To Right, between which vertical lines is the graph going down?
e) Interval(s) on which f(x) is constant: Reading the graph from Left To Right, between which vertical lines is the graph staying flat?
f) Look for the highest non-infinity point on the graph
g) Look for the lowest non-infinity point on the graph
