Answer:
4.5 miles
Step-by-step explanation:
Distance = 9 inches
1 inch = 1/2 mile
9 / 1/2 = 4.5
9 inch = 4.5 miles
P = m/v
To find the mass you have to do Density x Volume.
The volume of the cuboid is 0.18 m cubed and the density is 2.7g/cm cubed.
The 2.7 g/cm cubed must be converted into kg/m cubed to find the mass in kg. Which is 2,700 kg/ m cubed.
2,700 x 0.18 = 486 kg.
The mass of the marble in kg is 486kg
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
Answer:
t=7(1.75c)
Step-by-step explanation:
If I assume that she does the same number of chores each day the equation is t=7(1.75c)
this is because c is the number of chores
and for each chore she earns 1.75 so then for each day it is 1.75c
there are 7 days in a week so you need to multiply that all by 7
so that is 7(1.75c)
that little equation finds the total amount earned so then it is
t=7(1.75c)
