Graph A. We have a *positive* slope, so the boundary line will be rising as its x values increase, and our inequality is telling us we’re looking at all values of y less than, or *below* that boundary line. Graph A meets both these requirements.

Find the value of W and X

notka56 [123]

Answer:

W = 13.33

X = 13.10

Step-by-step explanation:

You use Trig

S = O/H. C = A/H. T = O/A

For W we have to find Adjacent using Opposite, so we're going to use Tangent

Now we have Tan = O/A and rearrange this to find Adjacent

Tan = O/A --> ATan = O --> A = O/Tan

then we plug in A = 12/Tan(42°) which gives us 13.3273.... I usually round up to the 2nd decimal, so 13.33

To find X we do the same thing with a little bit of additional work

Since we already did the work for the last one, we can just skip a few of those steps

A = 12/Tan(27°) which gives us 26.4322..... or 26.43

But that gives us the whole bottom bit, which is X+W, so just subtract the W

26.43 - 13.33 = 13.10

Sorry if I'm bad at simplifying my wording

I hope this is correct, my math seems right, but the picture is not to scale

I want to run 4 1/2 miles tonight. If I know running around my block is 3/5 of a mile, how many times should I run around the bl

sukhopar [10]

3/5 block mile is also 0.6 block mile
4 1/2 miles is also 4.5 miles

How many 0.6mi blocks do you run to run 4.5 miles?

4.5miles/0.6block mi = 7.5 or 7 1/2 blocks will equal 4.5 or 4 1/2 miles.

Check 7.5 blocks x 0.6 block mi = 4.5 miles

Same as you know one quarter equals $0.25 cent. And how many do you need to make one dollar that equals $1.00 ?

1/ .25 = 4 quarters

Can u please answer this question

Paha777 [63]

One Way:
We can change the mixed number to a decimal for comparing.

$1\frac{1}{4}$ m = $\frac{5}{4}$ m = 1.25 m

1.4 m    > 1.25 m
Darren   >   Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

$1\frac{1}{4}$ = $\frac{5}{4}$ (Luke)
1.4 = $\frac{7}{5}$ (Darren)
We need a common denominator to compare
$\frac{5*5}{4*5}$ (Luke)
$\frac{7*4}{5*4}$ (Darren)
$\frac{25}{20}$ (Luke)
$\frac{28}{20}$ (Darren)

$\frac{28}{20} > \frac{25}{20}$
  Darren >    Luke

By:
$\frac{28}{20}$ - $\frac{25}{20}$ = $\frac{3}{20}$
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
