A parcel has a mass of 500g. Calculate its weight. (Assume the gravitational field strength is 10N/kg).
Elan Coil [88]

Answer:

The weight of the parcel is 5 N

Step-by-step explanation:

we know that

Weight can be calculated using the equation:

 W=mg

where

W ----> weight (W) is measured in newtons (N)

m ----> mass (m) is measured in kilograms (kg)

g ----> gravitational field strength (g) is measured in newtons per kilogram (N/kg)

In this problem we have

g=10\ N/kg

m=500\ g

Remember that

1\ kg=1,000\ g

To convert g to kg

Divide by 1,000

so

m=500\ g=500/1,000=0.5\ kg

substitute the values in the equation

W=(0.5)(10)=5\ N

therefore

The weight of the parcel is 5 N

vovangra [49]
In this case, Maria is rent a kayaks that charge a $10 upfront fee, with an hourly rate of $7.50. Then the equation of the price should look like this: f(x)= 10+7.5x

If Maria has a total money of 70$, then the duration of rent should be:
f(x)= 10+7.5x
70= 10+ 7.5x
7.5x= 70-10
x= 60/7.5= 8 hours

1. In Suri's coin purse she has 6 dimes and
ollegr [7]

Answer:

The ratios are not equal

Step-by-step explanation:

Let

x ----> the number of dimes

y ----> the number of quarters

we know that

<em> Suri's coin purse</em>

x=6, y=4

The ratio of dimes  to quarters is

\frac{x}{y} =\frac{6}{4}

<em> Martha's coin purse</em>

x=5, y=3

The ratio of dimes  to quarters is

\frac{x}{y} =\frac{5}{3}

Compare the ratios

\frac{6}{4}=\frac{5}{3}\\6(3)=4(5)\\18\neq 20

therefore

The ratios are not equal
