Answer:

B

Step-by-step explanation:

2 angles and one side of one ΔBCE≡ 2 angles and one side of ΔKCE.

∴BE=KE

7p+7=37-3p

7p+3p=37-7

10p=30

p=3

KE=37-3p=37-3×3=37-9=28

Answer:

28

Step-by-step explanation:

What value of p makes both sides equal the same? P = 3

37 - 9 = 28

21 + 7 = 28

So line KE and BE both equal 28

Hope this helps, and have a good day :)!

There are two spinners containing only white and green slices. Spinner A has 4 white slices and 1 green slice. All the slices ar
MrRa [10]

Answer:

Step-by-step explanation:

Ok, lets list the important things

  • only green and white slices
  • all slices same size
  • spinner A has 4/5 white slices and 1/5 green slices
  • spinner B has 3/12 white slices and 9/12 green slices

The 4 options are:

  • spinner B lands on a green slice
  • spinner A lands on a white or green slice
  • spinner A lands on a white slice
  • spinner B lands on a yellow slice

We already know that choice 2 is 100% probable and option 4 is 0% probability, because in option 2, the spinner A ONLY has white or green slices so the spinner must land on the slice. In option 4, no matter which spinner is spun no yellow slices are available to land on.

the chance of option 1 happening is 9/12 which is 3/4 which is 75%

the chance of option 3 of happening 4/5 which is 80%

option 1 has a 75% chance

option 2 has a 100% chance

option 3 has an 80% chance

option 4 has a 0% chance

this means that the order is:

1. option 4

2. option 3

3. option 1

4. option 2

because it is least likely to most likely.

hope this helped you out and if you need any questions feel free to ask

good luck in maths!

Which expression can be used to approximate the expression below,for all positive number a,b and x where a =/ 1 and b=/ 1
rodikova [14]

Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

log_ax

The value of a is 1 and the value of b is 1.

According to the logarithm property,

log_mn=\frac{log_pm}{log_pn}

Using this property, we get

log_ax=\frac{log_bx}{log_ba}

The required expression is \frac{log_bx}{log_ba}.

log_1x=\frac{log_1x}{log_11}

log_1x=log_1x                   [\because log_aa=1]

Left hand side is equal to the right hand sides, therefore option 1 is correct.

A printer prints 28 photos in 8 minutes. how many photos does it take to print 35 more photos
svetlana [45]
First, we see how many photos can be printed in a minute. We do know that it can print 28 photos in 8 minutes.

To find how many photos it can print in 1 minute, we divide 28 by 8.

28÷8=3.5 

The printer can print 3.5 photos per minute. 

To see how many minutes it will take to print 35 photos, we divide 35 by 3.5.

35÷3.5=10.

It will take 10 minutes to print 35 photos.

Have a nice day! :)
