l = w - 12

2l + 2w = 60

2(w-12) + 2w = . 60

2w - 24 + 2w = 60

4w = 84

w = 21

21 - 12 = 9

Width is 21 feet, Length is 9 feet

The sum of three consecutive even numbers is 114 what's the smallest of these numbers​
laila [671]

Answer:

36

Step-by-step explanation:

consecutive even numbers are 2,4, 6...

Let the smallest of the 3 numbers be x.

2nd number= x+2

3rd number

=x+2+2

= x+4

sum of the 3 numbers= x +x+2 +x+4

114= 3x+6

3x= 114 -6 (-3 on both sides)

3x= 108 (simplify)

x= 108 ÷3

x= 36

Thus, the smallest number is 36.

Let's check!

36+38+40= 114 ✓

PLZ HELP I DONT UNDERSTAND A password for a security system must consist of a eater followed by two digits. How many possible pa
Talja [164]

Answer:

7020

Step-by-step explanation:

The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.

For each of these  there is any one of  permutations of 2 digits from 10

= 10P2 = 10! / 8! = 10*9 = 90.

So the answer is 78 * 90 =  7020.

Note I am assuming that the 2 digits picked are different - no duplicates.

please mark me brainliest!

I don’t know how to start with drawing the diagram for this question.
kogti [31]

Consider right triangles ADB and ADC in the figure, right angle D.

By alternate transversals ABD=63° and ACD=11°.

\tan 63 = \dfrac 8 y

\tan 11 = \dfrac 8{x+y}

y = \dfrac{8}{\tan 63}

x = -y +  \dfrac{8}{\tan 11}

x = \dfrac{8}{\tan 11} -  \dfrac{8}{\tan 63}

x \approx 37.08 \textrm{ meters}

That's in one second, so

Answer: 37 meters per second
