Answer:
x = 16
Step-by-step explanation:
Corresponding sides are proportional.
BE/CD = AE/AD
20/(3x+8) = (x-1)/(x-1+27)
20(x+26) = (3x+8)(x -1)
In standard form, this is ...
3x^2 -15x -528 = 0
x^2 -5x -176 = 0 . . . . . . divide by 3
(x -16)(x +11) = 0 . . . . . . . factor
x = 16
__
This is the positive value that makes the product zero. x=-11 will also make the product 0, but gives negative segment lengths in the geometry. It is an extraneous solution.
Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?
Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough
Answer:
1st question: 13 questions
2nd question: Mr.Philps will not have enough
Step-by-step explanation:
Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?
20 x 0.65 = 13
Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough?
1 gallon = 16 cups
27 students x 1 cup each = 27 cups
27 is greater than 16, so no, he will not have enough.

Answer:
7/24
Step-by-step explanation:
in order to get the fraction, you need to add all of the books read together; you should get 120.
Then add all of the books read in even classes(2nd grade and 4th grade) and you should get 35.
Then place 35 on top of 120 to form the fraction: 35/120.
Then simplify the fraction by finding the greatest common factor, which is 5, and divide 35 and 120 by 5 to get 7 and 24.

Answer:
31
Step-by-step explanation:
It had the same slope as y = 3 and passes through (1,5).
Answer:
y=5
Step-by-step explanation:
It has same slope of y=3, which means it is also a horizontal line. A horizontal slope will only have one y value. So, if we use the point (1, 5), we can say that the equation is y=5.

In ΔFGH, the measure of ∠H=90°, FH = 39, GF = 89, and HG = 80. What ratio represents the cotangent of ∠G?
Given:
In ΔFGH, the measure of ∠H=90°, FH = 39, GF = 89, and HG = 80.
To find:
The ratio which represents the cotangent of ∠G.
Solution:
In a right angle triangle, the ratio of the cotangent of an angle is
[tex]\cot \theta =\dfrac{Base}{Perpendicular}[/tex]
It is also written as
[tex]\cot \theta =\dfrac{Adjacent}{Opposite}[/tex]
In ΔFGH, the measure of ∠H=90°. So,
[tex]\cot G =\dfrac{HG}{FH}[/tex]
[tex]\cot G =\dfrac{80}{39}[/tex]
Therefore, the ratio for the cotangent of ∠G is [tex]\cot G=\dfrac{80}{39}[/tex].
it’s not A bc i got it wrong
The answer is A. unchanged

Can someone help me solve this problem?
Answer:
a = 8
b = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
I've attached a picture of the 45-45-90 triangle's formula, which is the length of the hypotenuse = [tex]\sqrt{2}[/tex] times the length of a leg (one of the sides of the triangle).
So, applying this to your problem, if 4[tex]\sqrt{2}[/tex] if one of the legs of the triangle, the other leg, which is b , would be the same length.
b = 4[tex]\sqrt{2}[/tex]
To solve for a, you would have to multiply the leg by [tex]\sqrt{2}[/tex].
a = 4[tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]
I would separate the 4 and the [tex]\sqrt{2}[/tex].
a = 4 x [tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex]
a = 4 x [tex]\sqrt{2 *2}[/tex]
a = 4 x [tex]\sqrt{4}[/tex]
a = 4 x 2
a= 8

There are 6 animals in the pen some are quails and some are goats if there are 20 legs in all how many quails and how many goats are there?
Answer:
4 goats
Step-by-step explanation:
Let us represent
Number of quails = x
Number of goats = y
Quails have 2 legs
Goats have 4 legs
Hence:
There are 6 animals in the pen some are quails and some are goats
x + y = 6...... Equation 1
x = 6 - y
if there are 20 legs in all how many quails
2x + 4y = 20..... Equation 2
We substitute 6 - y for x in Equation 2
2(6 - y) + 4y = 20
12 - 2y + 4y = 20
Collect like terms
- 2y + 4y = 20 - 12
2y = 8
y = 8/2
y = 4 goats
The number of goats there are 4 goats
Binomial Probability Distribution. How to determine the probability of one candidate of two winning.
A tree casts a shadow that is 9 meters long. A 54 meter tall building nearby casts a shadow that is 24 meters long. What is the height of the tree
Answer:
Height of the tree is 20.25 m.
Step-by-step explanation:
Length of building AB = 54 m
Length of tree DE = 9 m
Shadow casted by the building (BC) = 24 m
Shadow casted by the tree (CE) = 9 m
Since, ΔABC ~ ΔDEC
By the property of similar triangles, corresponding sides of the similar triangles will be proportional.
[tex]\frac{AB}{DE}=\frac{BC}{EC}[/tex]
[tex]\frac{54}{h}=\frac{24}{9}[/tex]
h = [tex]\frac{54\times 9}{24}[/tex]
h = 20.25 m
Therefore, height of the tree is 20.25 m.

PLEASE NEED HELP ASAP
Answer:
Trapezoid
Step-by-step explanation:
They're showing us (with red arrows/triangles) that the bottom and top are parallel, but do not state anything like it for the sides.
That means it's at least a trapezoid.
As nothing suggests the sides are parallel, it's likely not a parallelogram (and it doesn't look like one).
It's also not a kite, as there is no indication that pairs of neighboring sides are equal in length.
As we don't think it's a parallelogram, it's thus not a rectangle (every rectangle is a parallelogram).
Similar with rhombus (every rhombus is a parallelogram) and square (every square is a parallelogram AND a rhombus).
