Nikki makes $9.50 an hour working at Current Electronics. She plans to buy a DVD recorder that costs $269.60. Write and solve an inequality describing how many hours h Nikki will have to work to be able to buy the DVD recorder. 269.60 + h ≥ 9.50; 31 hours

9.50h ≥ 269.60; 29 hours

269.60 – h ≥ 9.50; 28 hours

269.60h ≥ 9.50; 30 hours

true? is that what you're asking or do you mean something else?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
