How do you find the percent of a whole number?
Ostrovityanka [42]
A percentage figure shows that the quantity of parts per one hundred a segment sum compares to. For instance, "85 percent" is another method for saying "85 sections for each 100." To calculate a percentage, the entire sum must be known,  in addition to the percentage or portion amount.

Rico thinks of a number between 30 and 40 that is represented by
Anna007 [38]
Hello,

x,y,z∈ IN

x=\frac{3}{4}*y
y=\frac{1}{3}*z

140
46\leq\ y\ \leq\ 50 ==>\ \frac{46*3}{4}\leq\frac{3y}{4}\leq\frac{50*3}{4}
35\ \leq\ z\ \leq\ 37==>
 x∈{35,36,37}
 y∈{47,48,49}
 z∈{141,144,147}

We must go futher:

if x=35 then y=4*35/3=46.666 not good , not whole
if x=36 then y=4*36/3=48 ok
if x=37 then y=37*4/3=49.333.. not good

So there is only one solution (36,48,144) for (x,y,z)

No problem with z for z=3/1*4/3*x=4x ==>whole.

List of reading his cell phone and monthly service please try and sell offers a new phone for $50 in unlimited service for a mon
Shtirlitz [24]

Answer:

After 5 months the cost of the two phones and monthly service be the same.

Step-by-step explanation:

1st service cost = $50 + $40x, where "x" represents the number of months

2nd service cost = $50x

Now we have to find the number of months the cost of the two phones and monthly service be the same.

Now we have to equivate and find the value of x.

50x = 50 + 40x

Subtracting 40x from both sides, we get

50x - 40x = 50 + 40x - 40x

10x = 50

Dividing both sides by 10, we get

x = 50/10

x = 5

After 5 months the cost of the two phones and monthly service be the same.

Hope you will understand the concept.

Thank you.

Which of the following expressions can be used to find how many cubes with edge length of 1/3 unit fit in a prism that is 5 unit
mash [69]

Answer:

5400 cubes can be fit into the prism.

Step-by-step explanation:

We are given the dimensions of prism as:

5 units by 5 units by 8 units i.e. 5 units×5 units×8 units.

Hence, the volume of the prism is given by:

Volume of prism=5×5×8=200 cubic units

Also the edge length of cube is given by= 1/3 unit.

Hence volume of 1 cube=

Hence volume of 1 cube= (1/27) cubic units.

Let 'n' cubes can be fitted into the prism.

Hence we have the relation as:

Volume of prism=n×Volume of 1 cube.

200=n×(1/27)

n=200×27

n=5400

Hence 5400 cubes can be fitted into the prism.
