Kelly uses cruise control to drive at a constant speed. She travels first 192 miles in 3 hours. At the rate, how long will it ta
ioda

Answer:

Step-by-step explanation:

rate = d / t

rate = 192 / 3

rate = 64 miles / hour

Now you want to know how long it can take to get 448 miles

d = r * t

t = d / r

t = 448/64

t = 7 hours.

You could actually do it using proportions.

192/3 = 448/x                   Cross multiply

192*x = 448*3

192*x = 1344                    Divide by 192

x = 1344/192

x = 7

Do this the way you feel is the best way.

It is March 30th and your project is due in about 7 weeks which of the following is the most accurate due date for your project
NNADVOKAT [17]
7 weeks = 7 x 7 = 49 days.
March has 31 days so from March 30 to March 31: 1 day
April has 30 days.
31 days already 
49 - 31 = 18
so May 18 is the most accurate due date

Elina [12.6K]

Answer:

Angle B = 106.6 degrees

Step-by-step explanation:

b^2= a^2+c^2-2*a*c*cosB

9*9 = 4*4 + 7*7 - 2*7*4*cosB

81= 16+49-56cosB           Subtract 16 and 49 from both sides

16= -56cosB           Divide by -56 on both sides.

cosB= -16/56         Take the arccosine of both sides

B=arccos(-16/56)                    

B= 106.6
