Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4

$\frac{154 \times 7}{4 \times 22} = r {}^{2} \\ r {}^{2} = 12.25 \\$

$r = \sqrt{12.25} \\ r = 3.5cm$

1/2m−5=23. What is the answer please tell me, it's very important.

olga_2 [115]

Answer:

m = 56

Step-by-step explanation:

1/2m - 5 = 23

add 5 to both sides

1/2m - 5 + 5 = 23 + 5

1/2m = 28

multiply both sides by 2

1/2m(2) = 28(2)

m = 56
