Let's call the short side "s"
short side = "s"
middle side = 3s
longest side = 2*3*s
perimeter = 45 cm
perimeter = s + 3s + 6s = 45
short side = 4.5
middle = 13.5
long side = 27

4.5 + 13.5 + 27 = 45

Rays PQ and PS are perpendicular to each other.<br><br> What is the measure of LRPS plzzzzz
inna [77]

Answer:

m<RPS = 53 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram shown;

m<QPR + m<RPS = 90

Given that;

m<QPR = x

m<RPS = x+16

Substitute into the formula;

m<QPR + m<RPS = 90

x+x+16 = 90

2x+16 = 90

2x = 90-16

2x = 74

x = 74/2

x = 37degrees

Get m<RPS;

Since m<RPS = x+16

m<RPS = 37 + 16

m<RPS = 53 degrees

Which expression is equivalent to one over five m − 20? (4 points)
exis [7]

Answer:

The equivalent to one over five m − 20 is one over five (m − 100) ⇒ B

Step-by-step explanation:

Let us solve the question

∵ One over five means \frac{1}{5}

∴ One over five m - 20 = \frac{1}{5} m - 20

→ By using the distributive property, take one over five as a common factor

  from both terms

∴ \frac{1}{5} m - 20 = \frac{1}{5} (\frac{\frac{1}{5}m}{\frac{1}{5}} - \frac{20}{\frac{1}{5}})

→ Simplify the bracket

∵  \frac{1}{5} m ÷ \frac{1}{5} = \frac{1}{5} m × 5 = m

∵ 20 ÷  \frac{1}{5}  = 20 × 5 = 100

∴  \frac{1}{5} (\frac{\frac{1}{5}m}{\frac{1}{5}} - \frac{20}{\frac{1}{5}}) = \frac{1}{5} (m - 100)

∴ \frac{1}{5} m - 20 = \frac{1}{5} (m - 100)

The equivalent to one over five m − 20 is one over five (m − 100)
