which is a good comparison of the estimated sum and the actual sum of 7 10/12+2 11/12? Greater or lesser

1 answer:

8 0

I would estimate 7 10/12 to 8 and i would estimate 2 11/12 to 3 so 8 plus 3 would equal 11 so that would be the estimate. the actual would be 10 8/11 so the estimate would be bigger.

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point

tankabanditka [31]

Answer:

Yes, the average speed for the entire trip from A to C is equal to $80\frac{km}{h}$

Step-by-step explanation:

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:

$V_a_v_e_r_a_g_e=\frac{x_2-x_1}{t_2-t_1}=\frac{Δx}{Δt}$

If the beginning and ending velocities for the motion are known, and the acceleration is constant, the average velocity can also be expressed as:

$V_a_v_e_r_a_g_e=\frac{V_1+V_2}{2}$

We Know that:

$V_1=70\frac{km}{h} \\\\V_2=90\frac{km}{h}$

Replacing the values:

$V_a_v_e_r_a_g_e=\frac{70+90}{2} =\frac{160}{2}=80\frac{km}{h}$

Raphael went to the store and bought 2 1/2 pounds of chicken for $9.00. What was the cost per pound of the chicken? Round your a

Anon25 [30]

Answer:

3 3/5

Step-by-step explanation:

Raphel bought 2 1/2 pounds of chicken for $9

Therefore the cost per round of the chicken can be calculated as follows

9÷5/2

= 9×2/5

= 18/5

= 3 3/5

A water balloon is thrown out of a window 96 feet above the ground. The balloon is traveling downward at 16 feet per second init

gulaghasi [49]

It hits the ground at h=0

0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t

t+3=0
t=-3, nope, we can't have negative time

at t=2, or 2 seconds
