TEAS with tyler MATH pt.1

express 15.2% as a decimal

We moved the decimal two places to the left or since its a percent, we can divide out of 100 and get the same answer

0.152

which of the following is true of the data set below?

4,10, 7, 13, 18, 21, 11

mean, median, range?

Remember we first organize them by lowest to highest in order and we then start making the

mean add up all the numbers and divide by 7

median is the middle number

range the biggest # minus the smallest #

what’s the answer?

make sure you read the question carefully and look for hints

AREA= the space inside / the amount of tile to COVER the floor

15 × 10= 150

what’s this?

perimeter

hint: the amount of fence that you need to go around a garden or something like that / going all around

Solve the following question

3( 4+2×4) / ( 4-6)²

remeber to do PEMDAS first

LEFT TO RIGHT go in order

(-2) ² = -2 times -2

=9

answer this

read closely it wanst the lowest pay price

make sure you add and ultiple what its asking for and find the cheapest one

company B: 390

company c= 400

a- wrong because it has to be greater than 50% in the pi chart

b- wrong because there’s another one with 5 % not just one but two of them = wrong

c= wrong because added all those 3 places gave me 35% its less than the university=45%= wrong

d= correct answer= university is 45% its saying northside is less than half of them so 45/2 = 22.5 which we get northside= 20% which is correct

answer

t can be the answer to anything if m is a different number

👉 Think: “It DEPENDS on something.”

Dependent variable: total cost 💰 → depends on how many apples you buy

t= correct

• m= independent variable (you put a value in)

make sure to follow the equation just how he has it

old value always

solve it

make sure you organize everything read it carefully have it organized and calculate it carefully

answer

make the best estimated guess with the numbers and make it look like they match and make sure they are right

might be UNSCORED

Dependent variable?

what do we have control over and what do we not have controlled over?

uv exposure and suncreen you can control over

you DO NOT DECIDE how much skin cancer you get

skin cancer DEPENDS on suncreen and uv Light

independent variable is the one we can change and control over

answer: C

answer

challenge questions

make sure to read it carefully moght trick you know the triangle formula and look at the answers to douible check

challenge question

algebra style

make sure it has paranthesis

answer this question

challenge topic

a- wrong the car is not moving staying at 20 all the way

b- correct it is going 20 mph and the car is moving

d- wrong

is 10 mph its going

we need to find C not C2

hyptenuse will equal C

challenge question

its asking per HOUR

we know that Biker A travels 5/6 of a mile in 30 minutes we want to go for an hour so 30 × 2= 60 minutes

1.666= 1.2/3

so 5/6= 0.8333 in 30 min x 2 = 1.6666 in one hour

biker B is ¾ in 20 minutes 3/4= o.75

20 minutes x 3= 60 m inutes= 1 hour

0.75 times 3 = 2.75= 2 1/4

158= 160 when rounded by tens 5 is in the tens place

12/ round tens place 12= 10 bc the tens is less than 5

45= 50 we are rounding tens place 5 is in the tens place so 50

160 × 10 × 50= 80,000

challenge question

veronica we made her like shes age of 5 its a estimated guess

5×4= t=20

highest priorities/ question will be shown

positive correlation= two measurments move in the same direction /^ ^ up

negative correlation= two mesurments move the opposite ways / up and down

in the picyure chart its showing us the amount of students studies the higher the test score

as time study increases test scores increases

so positive correlation

remeber PEMDAS with this

twice the speed of aircraft B = 2B +70

unscored

you CAN measure the pencil with centimeters

FEET no too big to measure

INCHES= yes small enough to measure a pencil

METER= a guiatar way to big to measure

micrometer= way too small

7/9

= 0.777777778

ROUND

0.78

challenge

x=30 for A

b=3.5 times 30= 105

Line graph = shows how one thing responds as something else changes

Scatter plot = shows how two measurements move together

Pie graph: used to show parts of a whole/

Bar graph: used f

or comparing categories or “votes”

Remember KFC

when dividing a fraction we multiply and flip

it gives us volume find length

high priotery

it’s asking for skin infections focus on that

turn the percent into a decimal

then we take the total of visits and multiple the decimal 0.09= 1440

high priotery topic

we can either simplify it into a small number giving us the number or just divide the number given into a decimal 15/21= 0.714

and 5/7 also gives us 0.714

high priotery question

ML→ L

must know 1000mL→ 1L

so divide

or trick movr decimal three places to left

then convert

highest prierity question

convert fraction into decimal

-1.29 is the lowest the bigger the negative number the lkowest

high prioretry

that works but also i did

1.6km/ 1 mile x 235 m/ 1= 376

we are looking for KM

high priorety question

solve for x

it says 38m3= 1L so 38ML/1L

2500m3/ x? whats x

we lined it up so they can match

do the butterfly method then divide by both sides

high proiorotery

unscored

how we know its right read carefully

A= sell computer

b= from individuals

c= from companies

and all matched

highest priorety

if one goes up one goes down

only for inverse
