A cube with edges that measure 10 centimeters has a volume that is twice as much as a cube with sides that measure 5 centimeters

. Is this true or false?
Mathematics

rodikova [14]3 years ago

Answer:

False

Step-by-step explanation:

We find the volumes of the two cubes and compare them.

volume of cube = side^3

The volume of the 10-cm cube is:

V = (10 cm)^3 = 1000 cm^3

The volume of the 5-cm cube is:

V = (5 cm)^3 = 125 cm^3

1000/125 = 8

The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.

The statement is false.

A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month.
kumpel [21]

Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that m represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for m months =  $25m

Total cost of the phone = Initial payment + Charges paid for m months

C = 25m + 50

It is a linear equation between two variables C and m.

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

y=Mx+c

M is the slope.

On Comparing, we get:

y = C, M = 25, x = m, c = 50

Therefore, the slope is <em>25</em>.

A cylidrical container of height 28cm and diameter of 18cm is with water. The water is then poured into another container with a
MAVERICK [17]

Answer:

23.9894949495cm is the depth of the container.

Step-by-step explanation:

Cylindrical container:

height: 28

radius: 9 (or 18/2)

pi * 9² = 254.4690049408

254.4690049408 * 28 = 7,125.1321383424 cm²

cylidrical container area: 7,125.1321383424cm²

Container:

length: 27cm

width: 11cm

27 * 11 = 297

7,125.1321383424 / 297 = 23.9894949495cm

I assume that the container with rectangular base is precisely full when tou pour the water into it.

And that your question was how deep the container was.
