In the diagram below, m∠A = 55° and m∠E = 35°. Which best explains the relationship between triangle ACB and triangle DCE?
The triangles are similar because all the pairs of corresponding angles are congruent. Therefore, the answer is D.
How to find similar triangles?Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
In a simpler term, similar triangle have the same shape but the sizes might varies.
Therefore, Let's check if ΔACB is similar to ΔDCE.
If two triangles have two of their angles equal, the triangles are similar.
Hence,
m∠A = 55 degrees
m∠E = 35 degrees
Therefore, using sum of angles of a triangle is 180 degrees,
∠ACE = ∠DCE = 90 degrees
m∠B = 35 degrees
Therefore,
m∠B = m∠E
∠ACE = ∠DCE = 90 degrees
Finally, the triangles are similar because al pairs of corresponding angles are congruent.

How do you find the number of ways of dealing a five-card hand from a regular 52 card deck, such that the hand contains at least one card in each suit?
The number of ways of dealing a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit is 2,593,812
What is the combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.
In order to find the number of ways of dealing with a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit, we can use the combination formula.
The combination formula is used to find the number of ways to select a certain number of items from a larger group without regard to order.
First, we need to find the total number of ways to select 5 cards from a 52-card deck.
This is given by the combination formula: nCr = n! / (r!(n-r)!)
Where n is the total number of items (52) and r is the number of items to be selected (5).
So, nCr = 52! / (5!47!) = 2, 598, 960
Now we need to subtract the number of ways to select a hand that doesn't contain at least one card of each suit.
We can select 4 cards from one suit and only one card from another suit in 4C1 * 48C4 ways = 448454239/24 = 5148.
Now we can subtract this number from the total number of ways to select 5 cards from a 52-card deck to find the number of ways to select a five-card hand that contains at least one card in each suit:
2598960 - 5148 = 2,593,812
Hence, the number of ways of dealing a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit is 2,593,812

Given rectangle MNOP below, NQ = 65. If MO = -6x+10, solve for x.
Answer:
x= -9.17
Step-by-step explanation:
To solve for x, we can use the information provided about the rectangle to set up an equation. Since opposite sides of a rectangle are congruent (have the same length), we know that MO = NP.
Therefore, we can set up the equation:
-6x + 10 = 65
To solve for x, we can subtract 10 from both sides:
-6x = 55
And then divide both sides by -6:
x = -9.17

the width is to be 14 feet less than 3 times the height. find the width and the height if the carpenter expects to use 28 feet of lumber to make it.
The width of the bookcase is 6 feet and height is 4 feet if the carpenter expects to use 28 feet of lumber to make it.
Let w = the width and h = the height of the bookcase. The width of the lumber you are using is not given.
Also, Let the height is x.
and, the width is 3x -14.
Since, we stated that this equals 28 feet and also that w = 3h - 14, we can insert this into the equation and use it to solve for h:
Now,
The total amount of lumber used to make the bookcase is:
L = 4w + 2h -------------------------- (1)
Now Putting Width and height in the Equation (1):
⇒ 28 = 4(3h - 14) + 2h
⇒ 28 = 12h - 56 + 2h
⇒ 28 = 14h - 56
⇒ 84 = 14h
⇒ h = 84/14
= 6 feet
Putting the value of height, h= 6 feet in
w = 3x -14
⇒ w = 3(6) - 14 = 4.
Therefore,
The width is 4 feet and the height is 6 feet.

Determine the convergence set of the given power series. n = The convergence set is . (Type your answer in interval notation.) Find a power series expansion for f'(x) given the expansion for f(x). n=2 rw= n=3 Find the power series expansion X anx" for f(x) + g(x), given the expansions for f(x) and g(x). n=0 19 = E 2*. * = 571 n=0 n=1 The power series expansion for f(x) + g(x) is .
The convergence set of the given power series is the set of all values of x in the interval (-|x-7|, |x-7|).
In order to determine the convergence set of the given power series, we can use the ratio test.
The ratio test states that if the limit as n goes to infinity of the absolute value of aₙ₊₁ / aₙ is less than 1, then the series converges for all x in the interval (-R, R) where R is the reciprocal of the limit.
The given power series is:
sigma n = 1 to infinity (17/ (n² + 5n))×(x - 7)ⁿ
We can apply the ratio test as follows:
aₙ₊₁ / aₙ = |(17/(n+1)² + 5(n+1))×(x - 7)⁽ⁿ⁺¹⁾ | / |(17/ (n² + 5n))×(x - 7)ⁿ|
aₙ₊₁ / aₙ = |(17/(n+1)² + 5(n+1))/(n² + 5n) × |(x - 7)|⁽ⁿ⁺¹⁾ | / |(x - 7)|ⁿ
As we can see the limit as n goes to infinity of the absolute value of
aₙ₊₁ / aₙ = |(x - 7)|
Let R = |x - 7|, therefore, the series converges for all x in the interval (-R, R)
So the series converges for all values of x in the interval (-|x-7|, |x-7|).

Heritability is typically divided into two categories, namely broad sense and narrow sense heritability.
The following formulas are used to calculate heritability in the broad sense:
H² = Vg / Vp
Where,
H² = Heredity
Vg = Genotypic Variance
Vp = Phenotypic Variance
FOR BACK FAT:
Vg = 13.7
Vp = 28.9
H² = Vg / Vp
H² = 13.7 / 28.9
H² = 0.474
FOR BODY LENGTH:
Vg = 27.2
Vp = 49.1
H² = Vg / Vp
H² = 27.2 / 49.1
H² = 0.553
These formulas are used to calculate narrow sense heredity:
H² = Vg / Vp
Where,
H² = Heredity
Vg = Genotypic Variance
Va = Additive Genetic Difference
FOR BACK FAT:
Vp = 28.9
Va = 7.98
H² = Va / Vp
H² = 7.98 / 28.9
H² = 0.276
FOR BODY LENGTH:
Vp = 49.1
Va = 12.4
H² = Va / Vp
H² = 12.4 / 49.1
H² = 0.252
Because back fat has a high narrow sense of heredity and a low broad sense of heritability, it is the best pick. Additionally, heritability in the restricted sense has good breeding value.

As per the given measurement , the area of the paper on the bottom of the cage 2736 square inches.
The formula to calculate the volume of the prism is written as
V = l x w x h
Where l refers the length , w refers the width and h refers the height.
Here we have know that the height of 24 inches and a volume of 6,480 cubic inches.
Now we have to apply the values on the formula in order to get the width of the cage,
=> 6480 = w x 24 x 12
=> w = 6480/288
=> W = 22.5
Therefore, the area of the bottom of the cage is calculated as,
=> A = 2[(24 x 22.5) + (24 x 12) + (22.5 x 24)]
When we simplify this one then we get the value of the area as,

Answer:
area: 576 cm ^2
perimeter: (48 + 24π) cm
Step-by-step explanation:
the semicircle taken out of the square (the white area) is equal to the semicircle added to the left of it. thus, we just have the area of a square. we know this because both have the same diameter and are semicircles. thus, our area is 24^2 = 576 cm ^2
for perimeter:
top: 24 cm
bottom: 24 cm
right: this is equal to half the circumference of a circle. this is because we know it's a semicircle taken out. circumference = πd = 24 * π. divide this by 2 to get 12π.
left: this is also equal to half the circumference of a circle = 12π

Elijah has a 41% debt-to-credit ratio. This means that for every $100 of available credit, he has used up $41. This ratio is calculated by dividing total debt by total credit limit.
Elijah's debt-to-credit ratio = Total Debt/Total Credit Limit

= 41% (rounded to the nearest whole percent)
Elijah's debt-to-credit ratio is a measure of how much of his available credit he has used. It is calculated by dividing his total debt by his total credit limit. In this case, Elijah currently owes a total of $2,127.50 on his revolving credit account, and his total credit limit is $5,750.00. When we divide his debit of $2,127.50 by his total credit limit of $5,750.00, we get a debt-to-credit ratio of 0.37. This is equivalent to 37%. When we round to the nearest whole percent, we get a debt-to-credit ratio of 41%. This means that for every $100 of available credit, Elijah has used up $41.

What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Given figure is a right angled triangle because it is marked in the figure.
For right angled triangle, we have the Pythagoras theorem,
Hypotenuse² = Base² + Altitude²
Given,
Length of hypotenuse = 18
Length of base = 9
Substituting in the Pythagoras theorem,
18² = 9² + x²
x² = 18² - 9²
x² = 243
x² = 81 × 3
x = √(81 × 3)
x = 9√3
Hence the value of the unknown side is 9√3.
