We can't tell.  Any certain letter doesn't have to mean the same thing wherever you see it.  You can use any letter you want to represent any quantity you want when you write an expression or a formula, as long as you clearly tell what it stands for.

C = 2r          This could mean anything.

It could mean that Julie has a great many pets.  For every rat she has,
she also has two cats.  Write a formula that tells how many cats she
needs for 16 rats.

It could mean that the Circumference of a circle is equal to 2 times
the length of the circle's radius.

It could mean that Rocko is baking oatmeal-raisin cookies.  He is
cutting each raisin in half, and putting 1/2 of one raisin in each cookie.
Write a formula that tells how many cookies he can make with 16 raisins.

Answer:

No Real Solutions.

Step-by-step explanation:

√(x-5)=8√(x-2)

Square on both sides,

(√(x-5))^2=(8√(x-2))^2

or,(x-5)=64(x-2)

or,x-5=64x-128

or,-5+128=64x-x

or,123/63=x

Therefore, x=41/21

If you plug x=41/21 in √(x-5)=8√(x-2) you do not get equals, so the problem has no real solutions.

Write 0.0059 in scientific notation.
polet [3.4K]
Hi!

When we write a number in scientific notation, we write it like this:
N × 10^{x}

N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.

Okay, so we need to move the decimal in the number <span>0.0059 to the right to make it between one and 10.
0.0059
00.059
000.59
0005.9
5.9

N = 5.9
5.9 </span>× 10^{-x}

Since we moved the decimal to the right 3 times,
x = -3

5.9 × 10^{-3}
^ the answer

Hope this helps! :)

Rob collects data about how many customers enter and leave a store every hour. He records a positive number for customers enteri
makkiz [27]
To answer the question, we utilize the given data and solve for the number of customers left in the store after every 1 hour interval.

Initially, there were 75 customers.

1:00 to 2:00 :        75 + 30 - 12 = 93
2:00 to 3:00   :      93 + 14 - 8   = 99
3:00 to 4:00   :      99 + 18 - 30 = 87
4:00 to 5:00   :  If the store does not accept any more customers except those who are already inside then, all 87 must leave between 4:00 to 5:00 in order to empty out the store by 5:00

ANSWER: (a) 4:00 to 5:00
                 (b) 87 customers

Lola has a rectangle piece of cardboard. the lenght of the cardboard is 14 inches. the width of the cardboard is half of its len
Vlad1618 [11]
Calculate the width
14:2=7
having given that the lenght is 14 in her slices too it means that she cuts it only in one direction so the width is
7:9=0.77777 (seven in period)

so she is pretty inacurate
