23 is less than 25 which means it's closer to 20, so you would round it down to 20. 1.75 is over 0.50, 1/2, so you would round it up to 2. If you multiply 2 and 20 you would get 40.
Number two gets the same explanation just with different numbers.
Answer:
Step-by-step explanation:
Jada is making circular invitations
we have d=12 cm, the radius r=6
she needs to find out the circumference
C=2x3.14x r
C=2x 3.14x6=37.68
180/37.68=4.77
she can make just 4 invitations
Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
hoped this helped!
Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute
Step-by-step explanation:
When x=0 (no minutes have elapsed), the value of the function is ...
f(0) = 75(2^0) = 75(1) = 75 . . . . the initial number of cells
As x increases by 1 (minute), the number of cells is multiplied by 2, so the 2 is the multiplier each minute. It indicates the number doubles. ("double" = "multiply by 2")
x is not defined, but for the function to make any sense, it must represent elapsed minutes.
Answer:
14.4 m/s
Step-by-step explanation:
The speed of the car can be found by dividing the distance by the time. The distance is 0.8m 9 times or 0.8(9)=7.2 meters and the time is 0.5 seconds
