Answer:
8.5
Step-by-step explanation:
Convert the percent to a decimal.
20% ÷ 100 = 0.2.
X = 17 ÷ 0.2.
X = 8.5
So 20% of 17 is 8.5.

Find the value of the ratio x over y if the equation is 5x²-13xy+8y²=0
Answer:
[tex]\frac{x}{y} = \frac{8}{5}[/tex]
Step-by-step explanation:
Given
[tex]5x^2 - 13xy + 8y^2 = 0[/tex]
Required
Find x/y
[tex]5x^2 - 13xy + 8y^2 = 0[/tex]
Expand
[tex]5x^2 -5xy - 8xy + 8y^2 = 0[/tex]
Factorize:
[tex]5x(x - y) - 8y(x - y) = 0[/tex]
Factor out x - y
[tex](5x - 8y)(x - y) = 0[/tex]
Divide both sides by [tex](x-y)[/tex]
[tex]5x - 8y = 0[/tex]
Add 8y to both sides
[tex]5x = 8y[/tex]
Divide both sides by 5
[tex]x = \frac{8}{5}y[/tex]
Divide both sides by y
[tex]\frac{x}{y} = \frac{8}{5}[/tex]
1. If line m | line n and angle6 measures 55 degrees , what is the measure of angle1
Answer:
m<1 = 125°
Step-by-step explanation:
Given that line m is parallel to line n, therefore:
m<2 = m<6 (corresponding angles theorem)
m<2 = 55°
Therefore,
m<1 = 180° - m<2 (linear pair)
m<1 = 180° - 55°
m<1 = 125°

Find the area and perimeter of the polygons formed by the algebra tiles below: area: y X perimeter: 1 area: perimeter: 2
Answer:
The answer is below
Step-by-step explanation:
a)
The area of the figure = sum of the area of the individual polygons
The area of the figure = x + 1 + y + 1 + x = 2x + y + 2
The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6
b)
a)
The area of the figure = sum of the area of the individual polygons
The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3
The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6

Answer:
x=3.5
Step-by-step explanation:
12x=4(x+2)+20
multiply the parentheses by 4
12x = 4x+8 +20
add 20 to 8
12x = 4x +28
subtract 4x on both sides
8x = 28
divide both sides by 8
x=3.5
Answer:
9.[tex] \:\:x = 3. 5[/tex]
10. y = 8x + 12
Step-by-step explanation:
9.
12x = 4(x + 2) + 20
12x = 4x + 8 + 20
12x - 4x = 28
8x = 28
x = 28/8
x = 7/2

Slope (m) = 8
Line is crossing y-axis at (0, 12)
y-intercept (b) = 12
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging the values of m and b in the above equation, we find:
y = 8x + 12

-15 = m
Step-by-step explanation:
-16 = -1 + m
-16 + 1 = m
-15 = m
Why does -1 became +1 , It is because you are adding 1 on both side so that we can cancel out the -1 and it will rest the m.
like this;
+1 -16 = -1 + m +1
-16 + 1 = (0 or nothing) + m
-15 = m

7. A mailer for posters is a triangular prism as shown. Find the surface area of the mailer. (Example 3) 4.7 in. 18 in. 4.7 in. M.lohn Sininh 1234 Anysvert Anytown, 4 in. 5 in.
Answer:
279.2 squared inches
Step-by-step explanation:
first find the base of the triangular prism which is 18*5=90.
then multiply 18*4.7 to get 84.6 then multiply that by 2 to get 169.2
then find the area of the triangles which is 4*5= 20 then add it all up which is equal to 279.2 ( 90 + 20) + 169.2= 279.2

¿CÓMO ALCANZÓ EL HOMBRE EL CONCEPTO DE INFINITO?
Trabajar con el infinito es un asunto complicado. Las paradojas de Zenón alertaron por primera vez a los filósofos occidentales sobre esto en 450 a. C. cuando argumentó que un corredor rápido como Aquiles tiene un número infinito de lugares para alcanzar durante la persecución de un corredor más lento. Desde entonces, ha habido una lucha por entender cómo usar la noción de infinito de una manera coherente. Este artículo se refiere al importante y controvertido papel que juegan los conceptos de infinito y el infinito en las disciplinas de la filosofía, las ciencias físicas y las matemáticas.
Los filósofos quieren saber si hay más de un concepto coherente de infinito; qué entidades y propiedades son infinitamente grandes, infinitamente pequeñas, infinitamente divisibles e infinitamente numerosas; y qué argumentos pueden justificar las respuestas de una forma u otra.
Aquí hay algunos ejemplos de estas cuatro formas diferentes de ser infinito. La densidad de la materia en el centro de un agujero negro es infinitamente grande. Un electrón es infinitamente pequeño. Una hora es infinitamente divisible. Los números enteros son infinitamente numerosos. Estas cuatro afirmaciones están ordenadas de mayor a menor controversia, aunque las cuatro han sido cuestionadas en la literatura filosófica.
Este artículo también explora una variedad de otras preguntas sobre el infinito. ¿Es el infinito algo indefinido e incompleto, o es completo y definido? ¿Qué quiso decir Tomás de Aquino cuando dijo que Dios es infinitamente poderoso? ¿Estaba en lo cierto Gauss, que fue uno de los más grandes matemáticos de todos los tiempos, cuando hizo la controvertida observación de que las teorías científicas involucran infinitos simplemente como idealizaciones y simplemente para facilitar la aplicación de esas teorías, cuando en realidad todas las entidades físicamente reales son ¿finito? ¿Cómo cambió la invención de la teoría de conjuntos el significado del término "infinito"? ¿Qué quiso decir Cantor cuando dijo que algunos infinitos son más pequeños que otros? Quine dijo que los primeros tres tamaños de los infinitos de Cantor son los únicos en los que tenemos motivos para creer. Los platónicos matemáticos no están de acuerdo con Quine. ¿Quién tiene razón? Veremos que existen profundas conexiones entre todas estas cuestiones.
Four points are drawn on the coordinate plane and connected with straight lines to form a rectangle. Three of the vertices of the rectangle are located at (2, 1), (2, 4) and (4.4). a What are the coordinates of the fourth vertex of the rectangle? b. What are the dimensions of the rectangle? c What is the area of the rectangle?
You have 2 points with the same x value of 2 and 2 points with the same y value of 4.
You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.
The missing point would need to be (4,1)
The width would be x2-x1 = 4-2 = 2 units
The length would be y2-y1 = 4-1 = 3 units
Area = 3x 2 = 6 square units
A card game is being played and the 7 of clubs, 9 of hearts, 10 of spades, and
10 of hearts are drawn. In order to win the hand, the next card must be higher
than the highest card already on the table. Assuming the game is played with
a single deck, what is the chance that the next card drawn will win the hand?
(An ace has a value of 1.)
A. 12%
B. 24%
C. 3%
D. 25%
Answer:
Step-by-step explanation:
Only j,q,k beat 10 and there are four each of them so there are 12 cards that will beat the ten. 4 cards have already been drawn so there are 52-4=48 cards left in the deck, so the probability of beating the 10s is
12/48
1/4
Which is 25%
please help me its hard!
Answer:
600
Step-by-step explanation:
Consider ABC and ACD as two triangles. And AC as a base to both of them
so,
AC = AO + OC
= 15 + 25
= 40
Now the area of ABC =
[tex]\frac{1}{2}\times AC\times OB\\= \frac{1}{2}\times 40 \times 10\\= 200[/tex]
In the same way, the area of ACD =
[tex]\frac{1}{2}\times AC\times OD\\= \frac{1}{2}\times 40 \times 20\\= 400[/tex]
Both added together 400 + 200 = 600

Answer: 0.075
Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.
Answer:
7.5% = 0.075
Step-by-step explanation:
Whenever you're converting a percentage into a decimal, you multiply the percentage by 100, or move the decimal point two points to the left. So, 7.5% as a decimal is 0.075.

Answer:
12.5 sq. units
Step-by-step explanation:
Area of a Trapezoid Formula: (see the image attached)

Answer:
The answer is A.
Step-by-step explanation:
The school needs AT LEAST $5000 dollars. The only answers that say at least $5000 is A. and C. Then the school gave them 1000. So the answer would state that 60 students times the amount of money needed to be raised plus the additional money the school gave them is greater than 5000.
A. is saying that 60 students times X, which equals how much money each member has to raise. Plus 1000, which is how much the school gave them. Is greater than 5000 which is at least how much the need to raise.
