Complete Question

Gatley’s Sport Shack and Camden Sports both carry the same brand of ski socks. At Gatley’s, 5 pairs of the ski socks cost $36.25. At Camden Sports, 4 pairs of the ski socks cost $32.60. A. What is the unit cost per pair of ski socks at both Gatley’s Sport Shack and Camden Sports?

Answer:

The unit cost per pair of ski socks at the Gatley’s Sport Shack is $7.252

The unit cost per pair of ski socks at the Camden Sports is $8.15

Step-by-step explanation:

a) At Gatley’s, 5 pairs of the ski socks cost $36.25.

The unit cost per pair of ski socks at the Gatley’s Sport Shack is calculated as:

5 pairs = $36.26

1 pair = $x

Cross Multiply

5 × $x = 1 × $36.26

$x = $36.26/5

$x = $7.252

Therefore, the unit cost per pair of ski socks at the Gatley’s Sport Shack is $7.252.

b) At Camden Sports, 4 pairs of the ski socks cost $32.60

The unit cost per pair of ski socks at the Camden Sports is calculated as:

4 pairs of socks is = $32.60

1 pair of socks = $x

4 × $x = 1 × $32.60

$x = $32.60/4

$x = $8.15

The unit cost per pair of ski socks at the Camden Sports is $8.15.

36+7x=64 what is the answer ?

Answers

Answer:

x=4

Step-by-step explanation:

First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.

To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.

Therefore, the correct answer is 4!

El tubo de entrada que se aplica presión de aire para operar un gato hidráulico tiene 2 cm de diámetro. El pistón de salida es de 32 cm de diámetro. ¿Qué presión de aire (presión manométrica) se tendrá de aire se que haga que con para levantar un automóvil de 1800kg?

Answers

Responder:

57288.35 kN

Explicación paso a paso:

Paso uno:

datos dados

diámetro del tubo de entrada = 2 cm = 0.02 m

área = πd ^ 2/4

área = 3.142 * 0.02 ^ 2/4

área = 0.0003142m ^ 2

A1 = 3.14 * 10 ^ -4 m ^ 2

diámetro del pistón de salida = 32cm

masa del coche = 1800 kg

peso del coche = 1800 * 10 = 18000N

carga F2 = 18000N

Segundo paso:

Se requiere la presión aplicada P2

Aplicando la ecuación de presión para un fluido incompresible tenemos

P1 = F2 / A1

P1 = 18000 / 0,0003142

P1 = 57288351.36

P1 = 57288.35 kN

Write an equation of the line in slope-intercept form.

Answers

Answer:

y=mx+b where m is the slope and b is where the line crosses the y axis.

THe line crosses the y axis at 0, 2 so 2 = b

the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:

y=1/3x+2

Step-by-step explanation:

Answer:

Y= -1/3x + 4

Step-by-step explanation:

Slope equation= y2 - y1/x2 -x1

Subtract 2-3/ 0-3 = -1/3

Choose an ordered pair to use for this problem. I chose 3,3.

Y-intercept equation- y = mx + b

3 = -1/3 * 3 + b

Multiply-1/3 * 3

3 = -1 + b

Add 1 to get rid of -1 and get b alone

3 + 1 = -1 + 1 +b

4= b

Now plug in your numbers to your equation.

Y= -1/3x + 4
