the distance between Nick and Sara's house is 546m. Nick can walk 1.3 m/sec. Using the formula d=rt, where d is distance, r is r
maks197457 [2]
D=rt and we are told d=546 and r=1.3m/s so

1.3t=546  divide both sides by 1.3

t=420 seconds so

420s(min/60s)=7 min

So it takes him 7 minutes to walk to Sara's house.

If you cannot locate the csc button on your calculator, you can also use </span>\frac{1}{sin(40)}<span> as csc is its inverse.

Also, it is helpful to note that some calculators have both a degrees and a radians mode for trigonometric functions. You will need to make sure that you are in degrees in order to use a calculator to solve this. </span>

4

Step-by-step explanation:

ΔABC is congruent with ΔDEF.  That means the corresponding sides are congruent.

Look at the order of the letters.  EF are the last two letters of ΔDEF.  So this corresponds with the last two letters of ΔABC.  Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.
