Ceva's Theorem states that given any triangle △ABC, the segments from A, B, and C to the opposite sides of the triangle are concurrent precisely when the product of the ratios of the pairs of segments formed on each side of the triangle is equal to 1.

Help me with this question ASAP!!!!!!!!!!!!
Answer:
Yes by AA similarity
Step-by-step explanation:
<ACB is congruent to <ECD by vertical angles, so we have one pair of comgruent angles.
<B is congruent to <CDE because they are both 90 angles, so we have another pair of congruent angles.
Triangle ABC is similar to triangle EDC by AA similarity.

identify the slope and y-intercept of the function y=-5x+4 (brainlyest to correct answer)
Answer: A. The slope is -5, and the y-intercept is (0,4)
Step-by-step explanation:
In standard form, a function is written as y = mx + b, where m = slope and b = the y-intercept
With that in mind, the m value is -5 and the b value is 4
Thus, the slope is -5, and the y-intercept is (0,4)
Who knows the answer for this question
Answer: 7
Work: So, the goal is to get z alone, so we are going to add 85 on both sides, cancelling on the side it's currently on. So, the new equation is going to be 25z = 175. Then, to get z even more lonely, we are going to divide 25 on both sides, and again cancelling it on the side it's currently on. So, the answer is z = 7. I hope this helps, and Happy Holidays! :)

There are 64 species of animals in the metropolitan zoo
5/8 are from North America
1/4 are from Africa
The remaining are from South America
How many species are from South America
Answer:
8 species are from South America
Step-by-step explanation:
In order to find the answer to this, you need to make the denominators of the North American and African species the same.
To do this, multiply 1/4 x 2/2.
You would then get 2/8. This means 2/8 of the species are African
Since you now have the same denominator, add the fractions together, and the total amount of North American and African species is 7/8, leaving 1/8 for the South American species.
You would then divide 64 by 8 to see how much 1/8 is worth in terms of how many species, and would then get 8.
A number minus 14 is more than 35
Answer:
False, -14 is less that 35
Step-by-step explanation:
Answer:
x-14>35
Step-by-step explanation:
x-14>35
1. Replace "A number " with x
x minus 14 is more than 35
Minus = subtraction
x-14 is more than 35
Is more than translates to the inequality >
x-14>35

You are at a European beach with 60 other visitors. 36 of them speak English. If you randomly meet two people on the beach, what is the probability that they both speak English
Answer:
Assuming I'm one of the 36 English speakers and the other 24 speak Spanish for illustration purposes. The problem can be modeled as 59 marbles with 35 E and 24 S marbles as N = 59 possible outcomes = n(E) + n(S) = 35 + 24.
So I reach into the pile of marbles (on the beach) and the probability that it's p(E) = n(E)/N = 35/59 = 0.593220339 when I meet the one person. ANS
I assume I remember that first person; so I remove him from the marbles (by avoiding him on the beach) and now my probability is p(E and E) = n(E)/N * n(E)-1/(N - 1) = 35/59*34/58 = 0.347749854 ANS
Following the same logic p(E and E and E) = 35/59*34/58*33/57 = 0.201328863 ANS
This last one is different from the first three. This one is p(E >= 1|4 attempts). We can trace out a probability tree to identify those branches that contain at least one E event. So:
EEEE p() = 35/59 * 34/58 * 33/57 * 32/56 =
EEES p() = 35/59 * 34/58 * 33/57 * 24/56 =
EESE p() = 35/59 * 34/58 * 24/57 * 33/56 =
ESEE p() = 35/59 * 24/58 * 34/57 * 33/56 =
SEEE p() = 24/59 * 35/58 * 34/57 * 33/56 =
EESS p() = 35/59 * 34/58 * 24/57 * 23/56 =
ESES p() = 35/59 * 24/58 * 34/57 * 23/56 =
SEES
SESE
SSEE
ESSS And so on, but...a big BUT...why do all this when
SESS
SSES
SSSE
SSSS
p(E>=1|4) = 1 - p(S and S and S and S) = 1 - 24/59 * 23/58 * 22/57 * 21/56 = 0.976652619 ANS. In other words we find the probability of not meeting an Englishman and take 1 minus that value to find the probability of meeting at least one.

12. Find the values of x and y in the diagram below.
Answer:
x = 15
y = 19
The value of the x and y are; 11/6, -5 and 18/4 in the linear equation.
What is linear equation?The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given parameters;
The equations are;
(4y - 18)
(6x - 11)
(x + 5)
Now put all equation equal to zero.
Then;
4y - 18 = 0
y = 18/4
And then;
6x - 11 = 0
x = 11/6
And
x + 5 = 0
x = -5.
Hence, In the linear equation, value of the x and y are 11/6, -5 and 18/4.

Solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex]
We know that [tex]\sqrt{x} = x^{\frac{1}{2}}[/tex]
Solving:
[tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}\\=((\sqrt{21}-2\sqrt{7} )^2)^\frac{1}{2}[/tex]
We know that [tex](a^2)^\frac{1}{2}=a[/tex]
= [tex]\sqrt{21}-2\sqrt{7}[/tex]
So, solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]
