Answer:
the number of grain of salt in the packet
5,401.23
Step-by-step explanation:
1 grain .................... 6.48x10^-5 kg salt
x grain.................... 0.35 kg salt
x= 5,401.23
a) The number of grains of salt in the packet are 5.4 x [tex]10^6[/tex] grains. b) The answer in part (a) is unlikely to be the actual number of grains of salt in the packet because the weight of a grain of salt can vary.
a) The number of grains of salt in the packet can be calculated as follows:
number of grains = total weight of salt / weight of one grain
= 0.35 kg / 6.48 x [tex]10^{-5[/tex] kg/grain
= 5.4 x [tex]10^6[/tex] grains
b) The answer in part (a) is unlikely to be the actual number of grains of salt in the packet because the weight of a grain of salt can vary. The average weight of a grain of salt is 6.48 x [tex]10^{-5[/tex] kg, but the actual weight can be anywhere from 6.2 x [tex]10^{-5[/tex] kg to 6.7 x [tex]10^{-5[/tex] kg. This means that the actual number of grains of salt in the packet could be anywhere from 5.2 x [tex]10^6[/tex] grains to 5.6 x [tex]10^6[/tex] grains.
In addition, the density of salt can also vary slightly, which would also affect the number of grains of salt in the packet.
Therefore, the answer in part (a) is only an estimate of the actual number of grains of salt in the packet.

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!

Answers
Answer:
20 + (-35)
Step-by-step explanation:
(-20) + 10 = -10
20 + (-35) = -15
Answer: 20+(-35)
Step-by-step explanation:
a.) -20+10
You owe me 20 dollars and you gave me 10 dollars already so how much more do you owe me? If you got you owe me 10 dollars, then you are correct. So the answer is -10 because the amount you owe is what still needs to be given so it is negative. (-10)
b.) 20+(-35) or 20-35
This problem would be you gave me 20 dollars but then took 35 dollars from me so how much do you owe you. You owe me 15 dollars since you gave me $20 a while ago and took from me. This would be a negative 15 since you owe it to me. (-15)
-15 is less that -10 since you would owe me more if you owed me 15 dollars. Also, -10 is closer to 0 than -15.

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

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
