What is a Rectangle ?A rectangle is a polygon with four sides , four angles and four vertices , The opposite sides are parallel and equal .
An expression representing the area of Rectangle is given
One of the side is 5x -8
The other side = ?
As Area of Rectangle = Length * Breadth
It can be calculated by Dividing Area by Breadth

Emily's family loves to work together in the garden. They have a slight preference for flowers, as 60%, percent of their plants are flowers and 40%, percent are vegetables. They have 50 plants growing in the garden. How many vegetable plants do they have?
Answer:
20 vegetable plants
Step-by-step explanation:
In order to figure this out, you need to find 40% of 50. You can solve that by doing 0.40 * 50, which gives you 20. I hope that helps!

ZA and ZB are
supplementary angles. If mA = (7x + 24)˚ and
m/B = (7x − 26)°, then find the measure of ZA.
-
The measure of ∠A is 115˚.
Given that, ∠A and ∠B are supplementary angles. ∠A=(7x + 24)˚ and ∠B=(7x − 26)°.
What are supplementary angles?Two angles are Supplementary when they add up to 180 degrees.
Now, ∠A+∠B=180°
⇒(7x + 24)˚+(7x − 26)°=180°
⇒14x− 2°=180°
⇒14x=182°
⇒14x=182°
⇒x=13°
Now, ∠A=7×13 + 24˚
⇒∠A=91˚+ 24˚=115˚
Therefore, the measure of ∠A is 115˚.

in poker, a royal flush is a hand with the ace, king, queen, jack and 10 of all one suit and is the best possible hand in the game. what is the probablity of a royal flush in a 5 card hand
The probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.
The combination is a way of selecting a smaller number of sets from a larger number of sets in no particular order.
If selecting r items from a set of n items, in no particular order, we use combinations, using the formula:
nCr = n!/{r!(n - r)!}.
In the question, we are asked the probability of a royal flush in a 5 card hand.
The number of ways of selecting 5 cards from a deck can be computed using a combination, 52C5, as we have 52 cards in a deck, 5 cards are to be chosen and the order is not in concern.
52C5 = 52!/{5!(52 - 5)!} = 52!/(5!.47!) = (52*51*50*49*48)/(5*4*3*2*1) = 2598960.
The number of hands that make a royal flush is only 4. 4 from each suit.
Therefore, the probability = 4/2598960 = 1/649740 or 0.0001539%.
Therefore, the probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.

Answer:

Step-by-step explanation:
Solve for x in both equations
2x<6
Divide both sides by 2:
x<3
3x+2>-4
Subtract 2 from both sides:
3x>-6
Divide both sides by 3:
x>-2
There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.
When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.
The circles are not filled in because the symbol is < and > rather than [tex]\leq and \geq[/tex]. When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.

What's Part of a 1 minute and 5 seconds?
62.5 seconds
Step-by-step explanation:
Part b assume the statement is true for n = k. prove that it must be true for n = k + 1, therefore proving it true for all natural numbers, n. t hint: since the total number of dots increases by n each time, prove that d (k) + (k + 1) = d(k+1).
The he statement d(k) + (k + 1) = d(k+1) is true for all natural numbers, n, by mathematical induction.
To prove that the statement is true for all natural numbers, n, we can use mathematical induction.
The statement we want to prove is that d(k) + (k + 1) = d(k + 1), where d(n) represents the total number of dots in a pattern of n squares.
Base Case (n = 1):
First, let's prove the statement for the base case, n = 1.
For n = 1:
d(1) + (1 + 1) = d(1) + 2
Now, consider a single square with 1 dot.
In this case, d(1) = 1.
So, we have:
1 + 2 = 3
Now, let's consider a pattern of 2 squares (n = 2).
The first square has 1 dot, and the second square has 2 dots. So, d(2) = 1 + 2 = 3.
So, the statement is true for n = 1.
Inductive Hypothesis (Assume true for n = k):
Now, assume that the statement is true for some arbitrary natural number k.
That is, assume that: d(k) + (k + 1) = d(k + 1)
Inductive Step (Prove true for n = k + 1):
To prove that the statement is true for n = k + 1.
d(k + 1) + (k + 2) = d(k + 2)
Now, consider a pattern of (k + 1) squares.
By the inductive hypothesis, assume that the statement is true for k squares:
d(k) + (k + 1) = d(k + 1)
Now, let's add one more square to the pattern.
This square will have (k + 2) dots.
So, the total number of dots in the pattern of (k + 1) squares plus the (k + 2) dots in the additional square is:
d(k + 1) + (k + 2)
And by the inductive hypothesis, d(k) + (k + 1) = d(k + 1).
Therefore:
d(k + 1) + (k + 2) = (d(k) + (k + 1)) + (k + 2) = d(k) + (k + 1) + (k + 2)
Now, simplify:
d(k + 1) + (k + 2) = d(k + 1) + (k + 1 + 1)
So, it is shown that for n = k + 1, d(k + 1) + (k + 2) = d(k + 1) + (k + 1) + 1.
Since it is assumed the statement to be true for k and proved it for k + 1, it is shown that the statement is true for all natural numbers, n, by mathematical induction.

First, since they have the same base, you can join them. Because it is division, you have to subtract the exponents.
4^(-11/3 -(-2/3)) = 4^-9/3 = 4^-3
Negative exponents turn the base into a fraction and 4^3= 64

\Triangles A C B and M Q R are shown. Sides A B and M R are congruent. Angles C A B and M R Q are 42 degrees. Angle C B A is 53 degrees. Angle M Q R is 85 degrees.
Are the triangles congruent? Why or why not?
Yes, all the angles of each of the triangles are acute.
Yes, they are congruent by either ASA or AAS.
No, AngleB is not congruent to AngleQ.
No, the congruent sides do not correspond.
By the ASA postulate, it can be said that the triangle ABC and triangle MRQ are congruent. Thus, option B is correct, Yes, they are congruent by either ASA or AAS.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
Using Angle Sum Property, in ΔMRQ
<M + <R + <Q= 180
<M + 42 + 85 = 180
<M = 180 -42
<M= 53°
Now, In ΔMRQ and ΔABC
<A= <R ,
<B = <M
AB = MR
Hence, By ASA criteria ΔMRQ ≅ ΔABC.
Thus, option B is correct, Yes, they are congruent by either ASA or AAS.

Answer: If for every independent unit(aka x), you multiply the dependent unit by the same amount(aka y).
Step-by-step explanation:
EXAMPLE:
(0,2) (1,6) (2,18) (3,54) (4,162)
As you can see, each time x increases by unit, you multiply the y unit by 3.
As an example, if you increase x by 4, you multiply the y unit by 3^4 = 81.
If this pattern is consistent with your whole table, you have an exponential function.
Hope this is useful.
