Answer:

6.5 cm

Step-by-step explanation:

The Pythagorean theorem applies. You want c for a=1.6, b=6.3.

c² = a² +b²

c² = 1.6² +6.3² = 2.56 +36.69 = 42.25

c = √42.25 = 6.5

The length of the hypotenuse is 6.5 cm.

On a trip over Thanksgiving Break Jenn's family has to drive a total of 325 miles.. If there are 126 miles to go and the car has

kherson [118]

The speed is 66.33 miles per hour

Step-by-step explanation:

Given

Total distance = 325 miles

They still have 126 miles to go. In order to find the distance they have covered, we will subtract the remaining miles from the total

So,

$Distance\ covered=325-126=199\ miles$

the car has been driving for 3 hours

So,

t= 3 hours

d = 199 miles

$Speed=\frac{d}{t}\\=\frac{199}{3}\\=66.33\ miles\ per\ hour$

The speed is 66.33 miles per hour
