Answer:
A. 60 miles per hour
B.120 customers per day
C.2.5 meters per second
D. $1.59 per pound
Step-by-step explanation:
Here we are asked to determine the unit rate for each one of the options given. By unit rate we mean the quantity for per unit quantity . Hence in order to find that we divide the two and quotient is our unit rate. Let us see how:
A. 420 miles in 7 hours
Unit rate = 
Unit rate = 60 miles per hour
B. 360 customers in 30 days
unit rate = 
Unit rate = 120 customers per day
C. 40 meters in 16 seconds
Unit rate = 
Unit rate = 2.5 meters per second
D. $7.96 for 5 pounds
Unit rate = 
Unit rate = $1.59 per pound
Answer:
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4) +(2x -6) = 180
5x = 190 . . . . . . . . . . . add 10, collect terms
x = 38 . . . . . . . . . . . . . divide by 5
∠D = 2(38) -6 = 70
∠B = 180 -70 = 110
The measures of angles B and D are 110° and 70°, respectively.
Answer:
In order to evaluate a function, replace the input variable (the number or expression given) (place holder, x). Replace the x by the number or word.
Step-by-step explanation:
First we raise both members of the equality to the square:
(√-4x) ^ 2 = (100) ^ 2
Then, we solve:
-4x = 10000
We cleared x in the last instance
x = 10000 / (- 4)
x = -2500
answer:
the solution of √-4x=100 is
A) x = –2500
