WILL MARK BRAINLIEST...The diagram shows four congruent circles with centres A, B, C and D touching one another. A small circle is placed in the centre so that it touches each of the four circles. given that ABCD is a square of area 36 cm², find the circumference of the small circle.​

Step-by-step explanation:

1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min

2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min

Together Time taken = n min/job ; invert to get rate = 1/n job/min

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

Equation :-

Rate + Rate = together rate

1/65 + 1/35 = 1/n

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

35n + 65n = 35*65

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

100n = 2275

n = 22.75 minutes = 22 minutes 45 seconds

Answer:

1

Step-by-step explanation:

5t = 5

divide equation by 5 to get rid of it

t = 1

This is because 5t means "5 times t". The t is a placeholder for a number.

To solve for t, we divide both sides by 5

5t = 5

5t/5 = 5/5

t = 1

Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.

Answer:

0.71

Step-by-step explanation:

Based on what we see here, we can deterime the probability of each flavor being drawn.

Apple: 11/38

Strawberry: 18/38

Lime: 9/38

So the probability of an apple NOT being drawn is 27/38. This is about 0.71.

Answer:

Step-by-step explanation:

Ok so u can’t divide a decimal with a whole number so u have to move the decimal poin from the 8 twice so it’s on the other side of the 8 and then there shouldn’t be any zeros before the 8 now divide 296 by 8 and instead of leaving the whole number like that u have to add the decimal point to it. So it should look like this 296.00 and then u can divide which is 3,700 hope this helped <3

Answer:

Four

Step-by-step explanation:

13- 5= 8

8/2=4

You simply do the problem in reverse.

Answer:

The number is 4

Step-by-step explanation:

Let the number = x

Double of x = 2*x = 2x

Then add 5 to it: 2x +5

2x +5 = 13

Subtract 5 form both side

2x + 5 - 5 = 13 - 5

         2x = 8

Divide  both sides by 2

       x = 8/2

x = 4

Step-by-step explanation:

-3/7. It is a rational because. It can be written as p/q form. Where p/q are non zero number. And in decimal it would be -0.42

Answer:

-3/7 is a rational because as it can be written as p/q form where p/q are integers and q≠0.

-3/7 = -0.4285

To the nearest hundredth,

=> -0.43

High school A:  3 vans + 12 buses = 504 students

High school B: 2 vans + 4 buses = 184 students

Multiply High school B by 1.5:

High school B: 3 vans + 6 buses = 276 students

Subtract High school B from High School A:

6 buses = 228 students

Divide students by buses:

Buses = 228 / 6 = 38 students per bus

Now solve for vans using high school A:

3 vans + 12(38 students per bus) = 504 students

Simplify:

3 vans + 456 students in buses = 504 students

Subtract students in buses from both sides:

3 vans = 48

Divide both sides by 3:

Vans = 16

Answer: vans = 16 students, buses = 38 students

Hi! I'm happy to help!

The recipe calls for 1/4 of a cup of cocoa, and we have 5/6 of a cup.

We use subtraction to solve for the difference:

5/6-1/4

To solve for this, we need to find a common denominator. We do this by finding the least common multiple of the two denominators we already have.

The least common multiple is 12, because that is the lowest number that both 6 and 4 are factors of.

We multiplied the 6 by 2 to get twelve, so, to make it equivalent, we have to multiply the 5 by 2 also.

10/12-1/4

Now, since we multiplied the 4 by 3 to get twelve, we need to do the same to the 1.

10/12-3/12

You never subtract denominators, only numerators. Now, all we have to do is 10-3:

10/12-3/12=

7/12

So, you would have 7/12 cup of cocoa left over if you made the cookies.

I hope this was helpful, keep learning! :D
