10.8 ft
14.6 ft
5.4 ft

Answers

Answer 1
Answer:

Answer:

14.6 ft

Step-by-step explanation:

Hello,  

thanks for leaving your query here in brainly, I think I can help you with this

te circumference of a circle is given by

Circumference=2*\pi *radius

Step one

solve for radius

Circumference=2*\pi *radius\n(Circumference)/(2*\pi ) =radius\nradius=(Circumference)/(2*\pi )

Step 2

replace

Let

Circumference=92 ft

radius=(Circumference)/(2*\pi )\nradius=(92\ ft)/(2*\pi )\nradius=14.64\ ft\n\to\ the\ nearest\ tenth\nradius=14.6\ ft\n

radius=14.6 ft

I hope it helps, have a fantastic day
Answer 2
Answer: circumference of circle = 2*pi*r=92
2*(22/7)*r=92
solving r = 92*7/44 = 14.6 ft

Explain how to compare numbers using place value ?

Answers

Place value is ones, tens, hundredths, thousandths.
I.e. 123.56

1 is in the hundreds place. 2 is in the tens place. 3 is in the ones place. And after the decimal you add -th to the end of the place value (tens->tenths). So 5 is in the tenths place (to the right of the decimal you skip the ones place). And 6 is the hundredth place. Hope this helps!

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.Write an equation to model this situation.

Answers

R=Number of rabbits

y=Years that have passed by { y ≥ 0 }

R=f(y) --> R is a function of y.
---------------------------------------------

Note that when:

y=0, R=4 ---> Point: (0, 4)

y=1, R=8 ---> Point (1, 8)

y=2, R=16 ---> Point (2, 16)

y=3, R=32 ---> Point (3, 32)

y=4, R=64 ---> Point (4, 64)

--------------------------------------------

So the equation you want is going to form a curved graph.

That equation is:

R={ 2 }^( y+2 )

*You can test out this function on any decent graphing software.
This is an exponential function.

At year x, the number of rabbits would be as follows:

y=4e ^((x*(In2)))

Where x is the number of years

A debate competition has participants from three different schools: 15 from James Elementary, 18 from George Washington University, and 12 from the MLK Jr. Academy. All teams must have the same number of students. Each team can have only students from the same school. How many students can be on each team?

Answers

Answer:

The number of students in each team can be : 3

Step-by-step explanation:

Since we have to form teams such that two conditions must be satisfied:

  • All teams must have equal number of students.
  • Each team can have only student from the same school.

Now on the basis of the above conditions to be satisfied we see that we can form "12 teams" such that each team must have "three students" from three different schools.

Hence, the number of students each team could have is 3.
Is the answer not 12?

If their only limitation is that they need equal numbers then it they can have 12.

Even though JE and GWU and more then 12 students they arent allowed to swap so the maximum that MLK Jr can have is only ever going to be 12

a giraffe can run 46.93 feet per second how many feet can it run in 1.8 seconds with out cross multiplying justify your awnser

Answers

46.93 x 1.8 = 84 .474 feet in 1.8 seconds
the multiplier is 1.8 as it is a 80% increase on the 1 second that we already have the information for

If the giraffe can run 46.93 in one second it can run 46.93*1.8=84.474 feet in 1.8 seconds.
