Question

i need some answers checked

Answer 1

@Mercury

Answer 2

hm. not quite. remember, sides across from bigger angles tend to be larger

UVT is the largest angle, right? so UT has to be the largest side

which side do you think is smallest?

Answer 3

uv

Answer 4

not quite

TUV is the smallest angle

therefore the side across from it, VT, is the smallest

so TU is the largest
VT is the smallest

making (A) the only viable choice

Answer 5

any two sides, added up, must be ~larger~ than the third side

8 + 7 = 15 so it has to be the next side up, 8 + 8 = 16

so 8 = your sol'n

Answer 6

hm, not quite, D is a valid triangle

you want to find the answer choice where you can pick two sides, add them up, and get something less than the remaining side

start with A and check all the possiblities

Answer 7

C?

Answer 8

C is valid (1/4 + 1/2 > 1/3, 1/2 + 1/3 > 1/4, 1/4 + 1/3 > 1/2)

if you check B again

1.5 + 5 is less than 7 so B is the only valid choice

Answer 9

this one is true

if you multiply both sides of an inequality by a negative number, the sign flips

Answer 10

A is not a valid triangle (10 + 11 is less than 22)

remember that any two sides must add up to be greater than the remaining side

you must test all the possible combinations within each answer choice

Answer 11

C then? it's close to 11

Answer 12

good, C is correct

4 + 8 > 11
8 + 11 > 4
4 + 11 > 8

Answer 13

hm, not quite

set up your proportion where

big rectangle long side/big rectangle short side = small rectangle longer side/small rectangle shorter side

Answer 14

then cross multiply and solve for x

Answer 15

16?

Answer 16

good, x = 16 = your sol'n

Answer 17

good

Answer 18

hm. not quite. if you notice, both sides of that expression cancel out to 1 which is not what we want

how would we get from a/b to ad? as a hint you need to multiply by something to
1. cancel out the b in the denominator, and:
2. get d in the numerator

Answer 19

well, let's start with step 1

what would we need to multiply (a/b) by to eliminate the b in the denominator?

Answer 20

uh..

Answer 21

CD?

Answer 22

a is being divided by b, right? so we can multiply by b

(a/b) * b = a

Answer 23

now, what would we need to do to get from

a

to

ad?

Answer 24

divide bc?

Answer 25

if we take a and divide bc

we get a/bc not ad

Answer 26

notice how you can just multiply

a

by d

to get ad

Answer 27

so in order to get from a/b to ad

you just multiply by bd

which answer choice shows multiplying both sides by bd?

Answer 28

C?

Answer 29

good so C = your sol'n

Answer 30

good

Answer 31

i actually feel like we did this one before...

Answer 32

so the whole scarf is 18 inches wide

each gauge is 4 inches wide

therefore we need (18/4) gauges

each gauge is 30 stitches wide

so # of stitches = 30 * (18/4) = 135 = your sol'n

Answer 33

hm

Answer 34

well, that's how I interpreted the problem

Answer 35

hm not quite, check the way you set up your proportion

10/21 = 13/(5x + 0.08) solve for x

Answer 36

5.04?

Answer 37

hm, not quite

cross multiply to get

10(5x + 0.08) = 13*21

then distribute the 10 and solve for x

Answer 38

had to correct a small typo

Answer 39

2.4?

Answer 40

*should be 0.8 not 0.08

but anyway, try applying the distributive property to the left side

A(B+C) = A*B + A*C

10(5x + 0.8) = ?

Answer 41

5.3

Answer 42

sorry got distracted by something

yeah that's correct, 5.3 is your solution

Answer 43

anything else? I have volunteer work all day tomorrow so I'd best be getting to sleep soon

Answer 44

@Vocaloid can we continue where we left off?

Answer 45

@ThisGirlPretty think you can get him online?
