Answer:
She hung 45reds, 30greens and 60whites
Step-by-step explanation:
If Sonia is hanging up decorations in the ratio of 3red: 2green: 4white, the total amount of different she hung is 3+2+4 = 9different colours.
Of she hung 135decorations in total, the number of red = 3/9 × 135 = 45reds
Number of green = 2/9 × 135 = 30greens
Numbe of white = 4/9 × 135= 60whites
She hung 45reds, 30greens and 60whites

Answer:
w = 
Step-by-step explanation:
Reverse the equation placing w on the left side
8w - 3 = - 12u + 13 ( add 3 to both sides )
8w = - 12u + 16 ( divide both sides by 8 )
w = 
Answer:
15 unit
Step-by-step explanation:
Applying
/RT/ = √[(y₂-y₁)²+(x₂-x₁)²]............. Equation 1
Where /RT/ = distance between point R and Point T
From the question,
Given: y₁ = -9, x₁ = 8, y₂ = -9, x₂ = -7
Substitute these values into equation 1
/RT/ = √[(-9-(-9))²+(-7-8)²]
/RT/ = √[(0)²+(-15)²]
/RT/ = √225
/RT/ = 15 unit
Hence the distance between point R and point T is 15 unit
