What is the volume of the cone?
A. 2876.7 yd
B. 4625.36 yd
C. 4258.44 yd
D. 2787 64 yd
Answers
Answer:
D. 2787.64 yd^3
Step-by-step explanation:
This is the formula for the volume of a cone:
[tex]V=\frac{1}{3} \pi r^2h[/tex]
The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.
[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]
Therefore, the radius of the base of the cone is 11 yd.
Now, we plug our values into the formula and solve.
[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]
Therefore, the volume of the cone is equal to 2787.64 yd^3.

You go shopping and spend $264 on shirts and shorts. You purchase a total of 9 items. Each shirt costs $24 and each pair of shorts cost $32. How many of each did you buy?
Answers
Answer:
3 shirts, 6 shorts
Step-by-step explanation:
A total of $264 is spent during shopping on shirts and shorts
Each shirt costs $24
Each shorts cost $32
Therefore the quantity of shirts and shorts bought can be calculated as follows
24× 3= 72
32×6= 192
192+72= 264
Hence 3 shirts and 6 shorts were bought

x = Horas Trabajadas 0 1 2 3 4
y = Dólares Ganados 0 3 6 9 12
La tabla anterior muestra la relación entre las horas trabajadas y el dinero en dólares, que obtuvo Juan trabajando a razón de $3.00 por hora. En esta tabla, podemos ver que el dinero ganado es igual al producto de las horas trabajadas por 3. Otra manera de decir eso es que la constante de variación o proporción es igual o 3. También se puede observar que cada vez que x aumenta en un 1, la variable y aumenta en 3. Otra manera de decir eso es que la razón de cambio es igual a 3.
En la aplicación de abajo, mueve el botón de la barra “constante de variación” a 3. Observa que los puntos de la gráfica coinciden con los valores en la tabla, y que con cada aumento de 1 en x, la variable y aumenta 3 y que la relación entre las variables es y = 3 × x .

En la aplicación de arriba, mueve el botón de la barra constante de variación a 2. Observa que los puntos de la gráfica coinciden con los valores en la tabla, y que con cada aumento de 1 en x, la variable y aumenta en 2 y que la relación entre las variables es y = 2 × x

En todas estas relaciones de los ejemplos anteriores, una variable es igual a otra variable multiplicada por una constante distinta de cero. Estas relaciones se conocen como proporciones directas o variaciones directas.
Definición
Dadas dos variables x y y, los enunciados:
y varía directamente como x,
y es directamente proporcional a x y
y es proporcional a x
todos significan que y = kx, para algún número real fijo k.
Al número k se le llama la constante de variación o constante de proporcionalidad. El valor de k también representa la razón de cambio de la relación. Es decir, cada aumento de 1 en x va a corresponder a un aumento de k en y.
Pasos para hallar la Fórmula para Relaciones de Variación Directa
Las relaciones de variación directa tienen la forma y = kx donde x y y son variables y k es una constante distinta de cero. La fórmula para una relación de variación directa se puede hallar mediante los siguientes pasos:
Paso 1: Traducir el enunciado a una fórmula de variación directa.
y es directamente proporcional a x significa
y =k·x
Paso 2: Sustituir las variables conocidas para encontrar k.
Paso 3: Sustituir k y escribir la fórmula.
Ejemplos
Ejemplo 1
u es proporcional a v. Si u = 16 cuando v = 4, escribe la fórmula para la relación entre u y v.
Paso 1: Traducir el enunciado a una fórmula de variación directa.
u es proporcional a v significa
u =k·v
Paso 2: Sustituir valores conocidos para encontrar k.
16 = k· 4
k=164=4
Paso 3: Sustituir k y escribir la fórmula.
u =4v
Conclusión: la fórmula para expresar la relación entre u y v es u =4v
Ejemplo 2
p varía directamente como z. Si p = 210 cuando z = 200, escribe la fórmula para expresar la relación entre p y z .
Paso 1: Traducir el enunciado a una fórmula de variación directa.
p varía directamente como z significa
p = k·z
Paso 2: Sustituir valores conocidos para encontrar k.
210 = k· 200
k=210200=1.05
Paso 3: Sustituir k y escribir la fórmula.

John has $10 in his bank account when he gets a job. He begins making $120 a day. A student found that
the equation that represents this situation is y = 10x + 120.
What is wrong with the student's equation? Complete the explanation and correct the student's error.
Answers
Answer:
The answer is switched.
Step-by-step explanation:
Given that John's bank account is $10 which is a constant (fixed) amount and he make $120 per day.
In the equation, x act as number of days so if you wants to find how much he earn after few days, you have to multiply $120 with the number of days.
The correct equation will be y = 120x + 10, 120 is the slope value and 10 is the y-intercept.

4 Tan A/1-Tan^4=Tan2A + Sin2A
Answers
tan(2A) + sin(2A) = sin(2A)/cos(2A) + sin(2A)
• rewrite tan = sin/cos
… = 1/cos(2A) (sin(2A) + sin(2A) cos(2A))
• expand the functions of 2A using the double angle identities
… = 2/(2 cos²(A) - 1) (sin(A) cos(A) + sin(A) cos(A) (cos²(A) - sin²(A)))
• factor out sin(A) cos(A)
… = 2 sin(A) cos(A)/(2 cos²(A) - 1) (1 + cos²(A) - sin²(A))
• simplify the last factor using the Pythagorean identity, 1 - sin²(A) = cos²(A)
… = 2 sin(A) cos(A)/(2 cos²(A) - 1) (2 cos²(A))
• rearrange terms in the product
… = 2 sin(A) cos(A) (2 cos²(A))/(2 cos²(A) - 1)
• combine the factors of 2 in the numerator to get 4, and divide through the rightmost product by cos²(A)
… = 4 sin(A) cos(A) / (2 - 1/cos²(A))
• rewrite cos = 1/sec, i.e. sec = 1/cos
… = 4 sin(A) cos(A) / (2 - sec²(A))
• divide through again by cos²(A)
… = (4 sin(A)/cos(A)) / (2/cos²(A) - sec²(A)/cos²(A))
• rewrite sin/cos = tan and 1/cos = sec
… = 4 tan(A) / (2 sec²(A) - sec⁴(A))
• factor out sec²(A) in the denominator
… = 4 tan(A) / (sec²(A) (2 - sec²(A)))
• rewrite using the Pythagorean identity, sec²(A) = 1 + tan²(A)
… = 4 tan(A) / ((1 + tan²(A)) (2 - (1 + tan²(A))))
• simplify
… = 4 tan(A) / ((1 + tan²(A)) (1 - tan²(A)))
• condense the denominator as the difference of squares
… = 4 tan(A) / (1 - tan⁴(A))

ΔABD is an obtuse triangle
Step-by-step explanation:
The type of a triangle according to its angle measures
The acute triangle ⇒ it has 3 acute anglesThe right triangle ⇒ it has 1 right angle and 2 acute anglesThe obtuse triangle ⇒ it has 1 obtuse angle and 2 acute angles0° < acute angle < 90°right angle = 90°90° < obtuse angle < 180°In triangle ABD
∵ m∠ABD = 100°
∵ m∠BAD = 50°
→ The sum of the interior angles of a triangle is 180°
∴ m∠ABD + m∠BAD + m∠BDA = 180°
∴ 100 + 50 + m∠BDA = 180
∴ 150 + m∠BDA = 180
→ Subtract 150 from both sides
∴ m∠BDA = 30°
∵ m∠ABD = 100°
∴ ∠ABD is an obtuse angle
∵ m∠BAD = 50° and m∠BDA = 30°
∴ ∠BAD and ∠BDA are acute angles
∵ ΔABD has 1 obtuse angle and 2 acute angles
∴ ΔABD is an obtuse triangle

Part A
How can you use compensation to find the number of miles he rode in 6 months?
Answers
Answer:
1164 are the total number of miles he rode in 6 months.
Step-by-step explanation:
Given that Juan rides his bike 97 miles to and from school each month.It means:
The miles to go to school = 97 milesThe miles to come back from the school = 97 milesThus,
Total miles in one month = 97 + 97 = 194 milesThus, the number of miles he rode in 6 months would be = 194×6 = 1164 miles
Therefore, 1164 are the total number of miles he rode in 6 months.

80 heart stickers does a pack of 140 stickers
Step-by-step explanation:
The number of heart stickers in a pack of 140 stickers is 60.
Given that, a sheet of 28 stickers has star and heart stickers.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, the number of star stickers in a sheet
= 28-16 =12
The ratio of star and heart stickers
= 12:16
= 3:4
Now, 3+4=7
Number of heart stickers = 3/7 ×140
= 60
Therefore, the number of heart stickers in a pack of 140 stickers is 60.

Step-by-step explanation:
first convert 1 1/2 into an improper fraction:
multiply the 2 and 1, you get 2, than add that to the current numerator to get a new one. You get 3/2 as your improper fraction
you now have: 3/2 ÷ 1/3
then turn the division sign into a multiplication sign by flipping the divisor:
you get 3/2 × 3/1
solve this:
multiply the numerators together, you get 9 as a new numerator
multiply your denominators, you get 2 as your new denominator
so now you have 9/2
next turn this into a mixed fraction, you get 4 1/2
so Sage did it right.
