Somebody Plz Help Me Im Failing

Answers

Answer 1
since all triangles add up to 180 and the little square on the bottom left is a 90 degree angle well
180-90=90
so angle B is 80
also the person above me answered in a rude way
it’s ok everything will be fine
you’ll get your grades back up
try your best!! :)

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 = 3

Step 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' = 16

Step 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]

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:)

Answers

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

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

Answers

It’s A- 19/12

Substitute y=0

Move the Variable to the left

Divide both sides by -12

Then the answer is 19/12
The slope would be 12. In that equation, 12= m. M means the same thing as slope.

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

Answers

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
