For number 18 you would first want to convert all the measurements so you can determine who walked the furthest.....In this case we will convert the feet's and inches to yards because yards are longer..

Janelle - 429ft. 8in = about 143 yards
Lydia- 460 ft = about 153 yards

in this case I believe Lydia walked the farthest...

The map of a walking trail is drawn a coordinate grid with three points of interest. The trail starts at R(-3,2) and goes to S(2

Answer:

12 units

Step-by-step explanation:

Given that :

R(-3,2)

S(2,2)

T(2,-5).

The total length ;

Distance between two points : √[(x2 - x1)² + (y2 - y1)²]

Distance between R and S :

R = (-3,2)

S(2,2)

√[((2 - (-3))^2 + (2 - 2)^2]

Sqrt(5^2 + 0^2)

D1 = 5 units

Distance between S and T:

S(2,2)

T(2,-5).

D2 = √[(2 - 2)^2 + (-5 - 2)^2]

D2 = sqrt(0^2 + (-7)^2)

D2 = 7 units

Hence, total length = D1 + D2 = (5 + 7) = 12 units

Joan is selling handmade bead necklaces at a local art fair. She paid $250 to reserve her booth. The cost of supplies for each n

Inga [223]

Y=250+2x is the amount she spends
y=12x is the amount she makes

If the amount she spent = the amount she makes then she break even

250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even

Answer is 25 necklaces

Sara is moving into a new apartment. The Resort complex charges a $600 security

vazorg [7]

Answer:

The rent is the same when 2 months have passed.

If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.

Step-by-step explanation:

Sara has two options, the resort complex and the uptown suites duplex, which can be represented by functions where "c" is the cost and "t" is the number of months Sara lives on each apartment.

The Resort complex:

$c_{resort}(t) = 600 + 950*t$

The Uptown Suites Duplex:

$c_{uptown}(t) = 300 + 1100*t$

To find the number of months she has to live in them in a way that they have the same cost, we need to find the value of t that makes both equations equal, this is done below:

$600 + 950*t = 300 + 1100*t\\1100t - 950t = 600 - 300\\150t = 300\\t = \frac{300}{150} = 2\\$

The rent is the same when 2 months have passed.

If she intends to live in them for 6 months, the cost of each are:

$c_{resort}(t) = 600 + 950*6 = 6300$

$c_{uptown}(t) = 300 + 1100*6 = 6900$

If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.
