Hey there! I'm happy to help!

Let's have the capacity be c. The tank is currently at 4/5c. We subtract 190 and then we are at 1/6c. Let's set this up as an equation and solve it.

4/5c-190=1/6c

We want to get the c all by itself to see the capacity of the tank. Let's get all of the c values on the left side of the equation and the numbers on the right by using inverse operations.

4/5c-190=1/6c

Add 190 to both sides.

4/5c=1/6+190

Subtract 1/6 from both sides.

19/30c=190

Divide both sides by 19/30.

c=300

So, the capacity of the tank is 300 liters of water.

Have a wonderful day and keep on learning! :D

Jon has $5,000 to invest in a savings account that has interest compounded annually. If he want his money to double in eight yea

Nataly_w [17]

$5000 × 1.1%=$55

$55 × 12 mos. in a year= $660 yearly on this percent

calculate
$660 × 8 years from now =$5280

so the answer would be 1.1% I assume

The perimeter of a rectangle is 46 m if the with were doubled and on length were increased by 5 their perimeter would be 66 what

Kamila [148]

Answer:

18 and 5

Step-by-step explanation:

if 'x' - is the length and 'y' - the width of the rectangle, then

2(x+y)=46 - perimeter of the original rectangle and 2(2x+(y+5))=66 - the perimeter of the new rectangle.

$\left \{ {{x+y=23} \atop {2x+y=28}} \right. \=> \ \left \{ {{x=5} \atop {y=18}} \right.$

Finally, the length is x=5 and the width is y=18.

An object has a mass of 225 g and a volume of 15 cm3.<br> Find the density of the object in g/cm3

ioda

Answer:

D=m/v

=225g/15cm^3

=15g/cm^3

Step-by-step explanation:

The formula for calculating density is: density=mass/volume.

after collecting data you will see that all the data is already in the question and there's no need to convert any units. Divide the mass by the volume and you'll have the density in g/cm^3
