molly paid 8% in sales tax on her holophone,a phone that shows the person you're talking to in 3D. if molly paid $416 in sales tax on the phone, what was its pre-tax price?

molly paid 8% in sales tax on her holophone,a phone that shows the

you do

.08 x /.08 = 416/.08

which is

1 x = 416/.08

which is
5200

i am bad at math

416/.08 then

That sounds like quite a lot, but I suppose a 3D holophone might be very expensive. On the other hand you might have meant she paid $4.16

do i do 0.08 /0.08=x 0.08/416=?

did u go to seeds?

0.08x = 416

Solve for x.

seeds ?

do u go to seeds for homeschool?

so it is $5200?

LOL, no, I went to Exeter then MIT where I graduated in physics in 1959 then got a PhD in engineering in 1968. I however home schooled my niece in math, physics, and chemistry so have some experience with home schooling.

Yes :) assuming that she really paid 416 in sales tax.

ok i now a Damon that gos to seed with me

sorry know

Mustard Seed home school ? I Googled it.

what is square yard? how do i do it?

no seeds of grace

u are 50?

i am 14

a square yard is a square one yard on a side at its most simple geometry. However it can be any plane figure that has that same area such as a circle of radius

pi r^2 = 1
or
r = sqrt (1/pi)

HELP ME PLZ

let's see now

I graduated grade 12 in 1955
so in 1955 I would have been about 12 + 5 = 17

2015 - 1955 = 60 years ago
+ already 17
= 77 years old approximately (and in fact correctly :)

1 square yard = 9

A square mile B square feet
C square inches D square kilometers
E square meters

u are 77 my mom is 69

my real mom is 45

1 square yard = 3 feet one one side times 3 feet on the other side = 9 square feet indeed

a square mile = 5280 feet times 5280 feet
= 27,878,400 square feet

so it is A?

1 square foot = 12 inches * 12 inches = 144 square inches

so
1 square mile = 27,878,400 square feet (144 square inches/square foot)
= 4,014,489,600 square inches

ok is it B?

1 square yard = 9 square feet. That is B

so 36 inches =1 yard

Remember I said

1 square yard = 3 feet one one side times 3 feet on the other side = 9 square feet indeed

Yes, 36 inches = 1 yard

i am bad at math!!!!!!!!1

so i do 36*36?

You are doing fine.

but there is a method to changing units like this

if you have 9 kittens

and 3 kittens/house

then you have
9 kittens ( 1 house/ 3 kittens)

kittens cancel
and you have (9/3) houses
= 3 houses

if you started with 3 houses and 3 kittens per house then

3 houses ( 3 kittens/house)
houses cancel and I have
3*3 = 9 kittens

i do not git it :(

yes

1 yard = 3 feet
1yard * 1 yard = 1 yard square = 3 feet*3 feet
= 9 feet square

so it is 1296 square inches?

Well I am sure you know that if you have 3 kittens per house and 3 houses that is 9 kittens :)

so it is C? squared inches?

36 * 36 = 1296 square inches

right

i hate math

i have 21 problems

But your original question was:

1 square yard = 9

A square mile
B square feet
C square inches D square kilometers
E square meters

The answer is B
1 square yard = 9 square feet

i am just bad at it i just want to give up

20 problems to go

well, let's see the next one.

Type it carefully.

ok

1 square kilometer=100
A square hectometers
B square dekameters
C square meters
D square decimeters
E square centimeters

i first do

1 cent =10 dec. right?

now i do

1 cent=20 meters.right?

are u there?

have stop helping me?

a square kilometer is

1000 meters * 1000 meters = 1,000,000 meters squared

1 hectometer/100 meters
1 dekameter/ 10 meters
etc

100 square hectometers = 100 * 100 meters * 100 meters = 1,000,000 meters squared
right
so A

Sorry, grandkids just came home from school.

how did u git that?

it is ok

I just tried them in order

1 hecktometer = 100 meters
100 * 100 = 10,000 square meters
so 100 of them is
1,000,000 square meters
which is a square kilometer

ok i git it

how many square meters are in 280 square centimeters?

so i divied

280/1000?

very few :)

1 square meter = 100 cm * 100 cm = 10,000 cm^2

so (1 m^2/10,000) cm^2

280 cm^2 * (1 m^2/10,000 cm^2)

= 0.028 m^2

=0.28

ok so it is 0.028

divide by 10,000 not 1,000 :)

answer is .028

i see

convert 1.2 liters to milliliters.

so i dived 10000/1.2?

no i motpliy 10000*1.2

=12000

right?

1.2 Liters ( 1000 mL/L) = 1,200 mL

yea

there are 1000 mL in a L

that is what milli means, one thousandth

write x times15 the algebra way. select the best possible choice.

A 15/x
B x *15
C 15x
D x15
E x(15)

i think it is B or C or D

15 x which is c

it is C

Yes

yes!!!!!!!!!!!!11

write x divided by 3 the algebra way.

A x/3
B x(3)
C 3/x
D 3x
E x/3

i think it is A

do u have fb?

I think it is E

x/3 is x over 3

I can not take you to facebook, rules.

ok why?

tutors are supposed to interact with student right here.

i know just asking

no why do u think it is E

Interesting, A and E are the same. typo ?

yes

i can not find the dividshon sinbol

oic, there is none, / is always used

but division symbol not normally used in algebra
x/3 would be normal
or

x
---
3

maybe :)

are u a techer?

the one with 2 dots one on the top and one on the dontom

so put A

I know what you mean, but it is not used in algebra

I was a college professor, engineering.

so just put A?

the one with the /

is right :)

tell whether each pair of expressions below is equivalent.

x+4/7 and 4/7 +x

i think the are equivalent

Yes they are equivalent

x0.03 and 0.03x

the are equivalent right?

I think so although I would have written

x * 0.03

0.03x is clear
x0.03 is confusing

so yes

I guess so, but I would never write x0.03

ok what would u write?

I would go with only 0.03 x

convert the percent to a decimal

12 1/4%

divide by 100

8% = 8/100 = 0.08

sorry what?

to get decimal from percent

divide percent by 100
