ABCD is a rectangle. find the length of each diagonal. AC= 3(x-2) and BD=x+18 what is AC? What is BD?
The diagonals of a rectangle are congruent. That means that their lengths are equal. One diagonal is AC, and the other diagonal is BD. AC must equal BD. We set their lengths equal and solve for x.
3(x - 2) = x + 18
Distribute the 3 on the left side.
3x - 6 = x + 18
Subtract x from both sides; add 6 to both sides.
2x = 24
Divide both sides by 2.
x = 12
Now that we know x = 12, we replace x with 12 in BD = x + 18 to find the length of BD.
BD = x + 18 = 12 + 18 = 30
Since the diagonals are congruent, the length of AC is also 30.
Answer: AC = 30; BD = 30
The length of the diagonals of the rectangle are AB = 30 and BD = 30
What is a rectangle?A 4-sided flat shape with straight sides where all interior angles are right angles (90°). Also, the opposite sides are parallel and of equal length.
Given that, ABCD is a rectangle and its diagonals are AC= 3(x-2) and BD=x+18
According to the property of a rectangle,
Diagonals of a rectangle are equal.
Therefore, AC = BD
3(x-2) = x+18
3x-6 = x+18
2x = 24
x = 12
AC = 3(12-10) = 30
BD = 12+18 = 30
Hence, the diagonals of the rectangle are AB = 30 and BD = 30

The length of a spring when it’s at rest is measured to be 0.56 centimeter. How many significant figures are there in this measurement?
A. 3
B. 2
C. 1
D. 0
Answer:
Option B - 2
Step-by-step explanation:
Given :The length of a spring when it’s at rest is measured to be 0.56 centimeter.
To find : How many significant figures are there in this measurement?
Solution :
There are two important rules to find the significant figure :
1) Non-zero digits are always significant.
2) Leading zeroes in front of decimal points are not significant.
Therefore, In the given measurement 0.56 cm.
There are only two significant figures.
So, Option B is correct.
The correct answer is option B. The measurement 0.56 has 2 significant figures.
To determine the number of significant figures in the measurement 0.56 centimeter, we follow the rules for identifying significant figures:
1. Non-zero digits are always significant.
2. Any zeros between significant digits are also significant.
3. Leading zeros (zeros to the left of the first non-zero digit) are not significant.
4. Trailing zeros in a decimal number are significant.
For the measurement 0.56:
The digit '5' is a non-zero digit, so it is significant.The digit '6' is a non-zero digit, so it is significant.The leading zero (the '0' before the decimal point) is not significant.Therefore, the measurement 0.56 has two significant figures.

In a parallelogram, consecutive angles are supplementary.
In a parallelogram, all angles are congruent.
In a parallelogram, consecutive angles are congruent.
In a parallelogram, consecutive angles are complementary.
In a parallelogram, consecutive
angles are supplementary
Answer:
In a parallelogram, consecutive angles are supplementary.
Step-by-step explanation:
Consecutive angles in a parallelogram have a sum of 180°; this means they are supplementary.
All angles in a parallelogram are not necessarily congruent; the second statement is therefore not true.
Consecutive angles in a parallelogram are not necessarily congruent; therefore the third statement is not true.
Consecutive angles in a parallelogram are not complementary, as they add up to 180° instead of 90°.

A school is building a rectangular soccer field that has an area of 6000 square yards. The soccer field must be 40 yards longer than its widht. Determine algebraically the dimensions of the soccer field, in yards
Answer:
length = 100 yd, width = 60 yd
Step-by-step explanation:
To solve this problem, you must set up an equation.
We know that he length (l ) is 40 yards greater than the width (w ). That means that the length is equal to the width + 40 yards, which can be written as l = w + 40. If the area of the field is 6000 square yards, that means the length times the width must be equal to 6000. Here is the equation that comes from it:
w * (w + 40) = 6000
You can simplify that even further:
w ^2 + 40w = 6000
Divide both sides by 40 to get rid of the coefficient:
w ^2 + w = 150
Now subtract w from both sides, then take the square root of both sides:
w = sqrt(150-w)
You could keep simplifying this equation until you finally arrive at your answer:
w = 60.
This means that the length, which is 40 more than the width, is 100.
If you want to prove this answer, just multiply the width by the length, which is 60*100, which gives you 6000 square yards; just what you need!
The value of dimensions of the soccer field, in yards are,
⇒ w = 60, l = 40
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
A school is building a rectangular soccer field that has an area of 6000 square yards.
And, The soccer field must be 40 yards longer than its width.
Let width of soccer field = w
Hence, Its length = w + 40
So, We get;
w (w + 40) = 6000
w² + 40w - 6000 = 0
w² + 100w - 60w - 6000 = 0
w (w + 100) - 60 (w + 100) = 0
w = - 100
w = 60
Since, Dimension are always positive.
Hence, w = 60
So, The value of dimensions of the soccer field, in yards are,
⇒ w = 60
l = 60 + 40 = 100

Answer:
ΔSTR is similar to ΔRTQ
Step-by-step explanation:
Given QRS is a right angled triangle. we have to find the similarity statement ΔSTR ~ Δ__
Let ∠S=x
In ΔSTR, by angle sum property
∠S+∠STR+∠SRT=180°
⇒ ∠SRT=90°-x
In ΔSRQ, by angle sum property
∠S+∠R+∠Q=180°
⇒ ∠Q=90°-x
In ΔSTR and ΔRTQ
∠SRT=∠Q=90°-x (proved above)
∠STR=∠RTQ (each 90°)
RT=RT (common)
Hence, by AAS rule ΔSTR≅ΔRTQ
∴ ΔSTR is similar to ΔRTQ
Option 4 is correct.
Answer:
RTQ
Step-by-step explanation:
Let ∠S=a, In ΔSTR, using angle sum property, we have
∠S+∠STR+∠SRT=180°
⇒ ∠SRT=90°-a
Again In ΔSRQ, using angle sum property, we have
∠S+∠R+∠Q=180°
⇒ ∠Q=90°-a
Now, In ΔSTR and ΔRTQ
∠SRT=∠Q=90°-a (proved above)
∠STR=∠RTQ (each 90°)
RT=RT (common)
Hence, by AAS rule,
ΔSTR≅ΔRTQ

Answer: A. 10
Step-by-step explanation:
because its the right answer
The equation of a hyperbola is x^2/24^2 - y^2/ (10)^2= 1.
We have given that, The equation x^2/24^2 - y^2/ (b)^2= 1 represents a hyperbola centered at the origin with a directrix of x = 576/26.
We have to find the value of b.
What is the general formula for hyperbola?[tex]\frac{(x-h)^2}{a^2} -\frac{(y-k)^2}{b^2} =1[/tex]
We have given that,
[tex]x^2/24^2 - y^2/ (b)^2= 1 \implies \frac{(x-0)^2}{24} -\frac{(y-0)^2}{b^2} =1[/tex]
a=24,h=0 and k=0
Now equation of the directrix
x=a^2/c...(1)
and we know x=576/26...(2)
Therefore from 1 and 2 we get
24^2/c=576/26.
isolate the c so we get,
C=26
C= center of focii
[tex]c=\sqrt{a^2+b^2} \\c^2=a^2+b^2\\b^2=c^2-a^2\\b=10[/tex]
So we get the value of b is 10.
Therefore the equation of a hyperbola is x^2/24^2 - y^2/ (10)^2= 1.

A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments. Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250?
A: f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0
B: f(n) = 250 − f(n − 1) ⋅ 0.4 + 48, n > 0
C: f(n) = f(n − 1) ⋅ 0.4 + 48, n > 0
D:f(n) = 250 − f(n − 1) ⋅ 0.6 + 48, n > 0
Let f(n) represent the number of bottles in the store on n-th week.
When n=0, f(n)=250.
Then 40% of the bottles were sold, this means that were sold 250·0.4=f(n)·0.4. The amount of bottles left is 250-250·0.4=f(n)-f(n)·0.4=f(n)·0.6.
If 48 new bottles arrived in shipments, then the amount of bottles became
f(n)·0.6+48=f(n+1).
Since n>0, then
f(n)=f(n-1)·0.6+48.
Answer: correct choice is A.
Option: A is the correct answer.
A: f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0
Step-by-step explanation:It is given that:
A store had 250 bottles of water.
Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments.
This means that the number of bottles that will be present in the store after 40% of the bottles will be sold at a particular week= 100%-40%=60% plus 48 new arrival
This means that each time the number of bottles in the store will be 60% of the bottles that were sold previous week plus 48.
Hence, if f(n-1) represent the number of bottle in the (n-1)th week then the number of bottles in the nth week will be represented by:
[tex]f(n)=60\%\ of\ f(n-1)+48\\\\i.e.\\\\f(n)=0.6\cdot f(n-1)+48[/tex]
how many 3 digit palindromes are divisible by 9?
Interesting problem.
A palindrome is a number which is identical when read/interpreted left-to-right or right-to-left. For example, 14241 is a palindrome, so is 444444.
A three digit palindrome must be made up of two distinct digits only, one for the first and last digits, and one for the middle, for example, 424, or 515, etc.
For a number to be divisible by 9, the sum of the digits must add up to a multiple of 9, such as 0, 9, 18, 27, etc.
We can now form a table of the possible 3-digit palindromes divisible by 9, starting with the first/last digits (=A), and finding the middle digit (=B). The number is therefore represented by the pattern ABA.
For example, when A=1, we have the number 1B1. For the number to be divisible by 9, B=7 so that sum=1+7+1=9, which is divisible by 9.
For each value of A (from 1 to 9) we can only find one value of B that makes the number divisible by 9. Thus we can only find nine such numbers, with A equal to 1 to 9.
Here's a list of the numbers
A B number
1 7 171
2 5 252
3 3 333
4 1 414
5 8 585
6 6 666
7 4 747
8 2 828
9 0 909
There are 9 unique 3-digit palindromic numbers that are divisible by 9. This is determined by the rule that a number is divisible by 9 if the sum of its digits is also divisible by 9, considering the constraints of palindromic numbers.
To find 3-digit palindromic numbers that are divisible by 9, we must first understand what qualifies as a palindromic number. A palindromic number is a number that remains the same when its digits are reversed. For a 3-digit number, this means the first and last digits must be the same (i.e., the form is aba, where a and b are digits).
Since our objective is to find those divisible by 9, we must recall the divisibility rule for 9: a number is divisible by 9 if the sum of its digits is also divisible by 9. For a 3-digit palindromic number aba, the sum of its digits is 2a + b. For this sum to be divisible by 9, a and b must be chosen accordingly.
The smallest 3-digit palindromic number is 101, and the largest is 999. To be divisible by 9, the sum of the digits must equal 9, 18, 27,..., or 81 (the largest sum for a 3-digit number where the first and last digits are the same). Since there are 9 possible sums (9 to 81 inclusive), and each sum offers a unique number that satisfies the palindrome and divisibility criteria, there are 9 such numbers.
Therefore, there are 9 unique 3-digit palindromic numbers divisible by 9.
