Oni was timing her 100 meter sprints. her first five sprints were 12.568 seconds, 11.426 seconds, 12.324 seconds, 11.981 seconds, and 12.601 seconds. which two estimation techniques will give the same result for the total number of seconds for all five sprints?

We can round off the digits to get a better estimate here.

Step-by-step explanation:

Oni's first five sprints were 12.568 seconds, 11.426 seconds, 12.324 seconds, 11.981 seconds, and 12.601 seconds.

The techniques that will give the same result for the total number of seconds for all five sprints are rounding off the digits to either nearest tenth or to nearest hundredth.

Nearest tenth :

Nearest hundredth :

We can see both times the estimate is same.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
