Use division to find the unit rate. <br><br> It rained 16 inches in 8 hours.
elena55 [62]

Answer:

2 inches per hour

Step-by-step explanation:

To convert to unit rate you can turn these 2 numbers into a fraction,

( the top part of the fraction is the inches unit and the bottom part is the hours)

16 and 8 into 16/8 then you simplify the fraction. So 16/8=2.

2 also equals 2/1 so its 2 inches every 1 hour.

Mathematics pls solve i need to check my answers bcs my teacher is sucky
Lilit [14]

If H is the circumcenter, then each of EH, FH, and GH are perpendicular bisectors of the legs BC, CD, and DB, respectively. So, for instance, EH cuts BC in half so that BE and EC have the same length.

Also, BH, CH, and DH are radii to the circumcircle of the triangle, so they all have the same length.

(1) CD = CF + FD = 2 • FD = 2 • 32 = 64

(2) CE = BE = 26

(3) HD = HC = 33

(4) GD = 1/2 • BD = 1/2 • 58 = 29

(5) By the Pythagorean theorem,

HG² + GD² = HD²

so

HG = √(33² - 29²) = 2 √(62)

(6) Similar to (5); by the Pythagorean theorem,

HF² + FD² = HD²

so

HF = √(33² - 32²) = √(65)
