100 is what percent of 250?

alisha [4.7K]

Answer:

100 is 40% of 250

Step-by-step explanation:

1. We assume, that the number 250 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 250, so we can write it down as 100%=250.

4. We know, that x% equals 100 of the output value, so we can write it down as x%=100.

5. Now we have two simple equations:

1) 100%=250

2) x%=100

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=250/100

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 100 is what percent of 250

100%/x%=250/100

(100/x)*x=(250/100)*x - we multiply both sides of the equation by x

100=2.5*x - we divide both sides of the equation by (2.5) to get x

100/2.5=x

40=x

x=40

now we have:

100 is 40% of 250

A cube has a side length of 7 cm a cylinder has a radius of 5 cm and a height of 4 cm

densk [106]

Answer:

Cube has larger volume than cylinder.

Step-by-step explanation:

Given:

Side of a cube = 7 cm

Radius of a cylinder (r) = 5 cm

Height of a (h) = 4 cm

Find:

Larger volume = ?

Computation:

Volume of cube = Side³

Volume of cube = 7³

Volume of cube = 343 cm³

$Volume\ of\ cylinder=\pi r^2h\\\\Volume\ of\ cylinder=\frac{22}{7} (5)^2(4)\\\\Volume\ of\ cylinder= 314.28$

Cube has larger volume than cylinder.

How many 0.5cm x 0.5 cm x 0.5cm cubes are needed to completely fill the rectangular prism measuring 4 cm x 3 cm x 3cm?mp

Juliette [100K]

Answer:

288

Step-by-step explanation:

The volume of the cube is 0.5^3 = 0.125, and the volume of the rectangular prism is 4*3*3 = 36.

Now, you just divide 36 by 0.125, which is 288.

I hope this helped.

John works a fortnightly wage of $750.00. If his basic week is 40 hours. what is his: Weekly wage basic rate and basic fortnight

Vladimir [108]

Answer:

Basic wage rate = $9.375 per hour

Step-by-step explanation:

Given :

Fortnight wage = $750

Basic week, hours worked per week = 40 hours

Weekly basic wage rate :

Fortnight = 2 weeks

Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375

Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour
