A cone has a base of [tex]5.4[/tex] and a height of [tex]8[/tex]. The diameter is [tex]6[/tex]. What is the volume? If you were to dilate the cone with a scale factor of [tex]2[/tex], what would the new radius be?
Answer:
(I) V = 24π ≈ 75.3982 units³
(II) V = 192π ≈ 603.186 units³

DilationsDiameter: d = 2rVolume of a Cone: [tex]V= \frac{1}{3} \pi r^2h[/tex]Step-by-step explanation:
Step 1: Define
Height h = 8
Diameter d = 6
Base b = 5.4 (not needed in calculations)
Step 2: Find radius r
Substitute: 6 = 2rIsolate r: 3 = rRewrite: r = 3Step 3: Find V of Normal Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (3)^2(8)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (9)(8)[/tex]Multiply: [tex]V= 24 \pi[/tex]Evaluate: [tex]V \approx 75.3982[/tex]Step 4: Find Dilations
Scale Factor: 2
Define radius: r = 3Dilate: r' = 3(2)Multiply: r' = 6Define height: h = 8Dilate: h' = 8(2)Multiply: h' = 16Step 5: Find V of Dilated Dimensions
Substitute: [tex]V= \frac{1}{3} \pi (6)^2(16)[/tex]Exponents: [tex]V= \frac{1}{3} \pi (36)(16)[/tex]Multiply: [tex]V= 192 \pi[/tex]Evaluate: [tex]V \approx 603.186[/tex]Bus 26 takes 2 3/4 hours to complete its bus route. How many times can Bus 26 complete its route in 16 hours?

Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $50 plus $0.35 per mile driven. Let m = the number of miles Mr. Parker drives for the day. Write an algebraic expression that shows the amount he will pay for the van. * 10 points \
Answer:
y=0.35m+50Step-by-step explanation:
Step one:
given data
the daily fee= $50
cost per mile driven =$0.35
Let m = the number of miles
let y be the total cost
Step two
Required
the expression for the total cost is
An algebraic expression that shows the amount he will pay for the van. is
y=0.35m+50

Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.
Mark this and return
Answer:
15x + 28y = 116
x + y = 6

En una tienda se anuncia la rebaja de 20% en todos sus artículos . Rafael elije una camisa y al llegar a la caja le informan que sea camisa , por traer etiqueta roja . Cuenta con un descuento adicional de 15% . Si Rafael pago $510.00 , cuál era el precio de la camisa sin los dos descuentos
Responder:
$ 750
Explicación paso a paso:
Dado que :
Descuento en todos los artículos = 20%
Descuento adicional dado = 15%
Monto final pagado por la camisa = $ 510
Precio de la camiseta sin descuento:
Sea el precio inicial de la camisa = x
Primer descuento obtenido = 20%
Precio pagado después de un descuento adicional del 15%
Primer descuento:
(1 - 0,20) * x = 0,8x
Segundo descuento:
(1 - 0,15) * 0,8x = 510
0,85 * 0,8x = 510
0,68x = 510
x = 510 / 0,68
x = $ 750

Answer:
A. because both variables (y and x) cancel each other out because they are equal. The answer to A is 0=6, which is clearly not true. All other choices have a solution that is possible, because at least 1 of the variables doesn't cancel itself out.
You roll a fair six-sided die. The die shows an even number or a number greater than four .
Solve it (NOT MULTIPLE CHOICE) find the probability:)
Answer:
4/6
Step-by-step explanation:
There are 3 ways to get an even number: 2, 4, 6 -> chance is 3/6=1/2
There is 1 way to get a number greater than 4: 5 (because 6 was already counted) -> chance is 1/6
Add up the probabilities: 1/2 + 1/6 = 3/6 + 1/6 = 4/6
The probability of rolling an even number or a number greater than 4 is 4/6
