Answer: 2,025/25=81

Answer:

81 is the scale of drawing.

Step-by-step explanation:

Area of the house in drawing = A =25 inch^2

Let the factor by which scaling is present in the drawing be s.

Area of the house in reality = A' =2025 feet^2

s\times A=A'

s\times 25 inches^2=2025 feet^2

\frac{2025}{25 }=81

81 is the scale of drawing.

When a negative number multiplies a negative number, it becomes positive

since it is multiplication, just multiply across, you do not need same denominators

5/8 x 16/25 = 80/200

80/200 = 40/100 = 20/50 = 2/5

2/5 is your answer

hope this helps

Apply the distributive property to factor out the greatest common factor. 18d+12 =18d+12=18, d, plus, 12, equals? (plz help quic
qaws [65]

Answer:

Answer is 6(3 d+2)

Step-by-step explanation:

It is given the expression as 18d+12

Let's find common factor by prime factoring the terms.

18 d =2*3*3*d

12= 2*2*3

Common factors for both terms are 2, 3.

So, G C F = 2*3=6

Take out 6 from both terms to factor further.

We do get 6(3 d+2)

What do I do for this question
padilas [110]

Answer:

Step-by-step explanation:

a + 9 = 15

a = 15 - 9

a = 6

c + 9 = 16

     c = 16 - 9

     c = 7

d = c + 9

   = 7 + 9

  = 16

e = d + 15

  = 16 + 15

e = 31

P(selecting a boy) = total boy /total pupils = 16/31
