Answer:

Sum of all three angles inside a triangle = 180°

Total number of parts = 3 + 10 + 7 = 20

Each part = 180 ÷ 20 = 9

Let us name the three angles of this triangle as ∠1 , ∠2 and ∠3 respectively .

Number of parts for ∠1 = 3 parts

∠1 = 3 × 9 = 27°

Number of parts for ∠2 = 10 parts

∠2 = 10 × 9 = 90°

Number of parts for ∠3 = 7 parts

∠3 = 7 × 9 = 63°

The three angles of this triangle measure 27° , 90° and 63° respectively

Measure of the smallest angle = 27°

Therefore , the measure of the smallest angle = 27° .

Kevin needs to convert 620 millimeters per minute to meters per hour. Which conversion factors should he use?
Annette [7]
Try this option:
1 meter=1000 mm; 1 hour=60 min. From another side: 1 mm=0.001 m. and 1 min=1/60 h.
Using this rule:
620 mm/h=0.06*620 m/h=37.2 meters per hour.

Suppose y varies inversely with x, and y = 25 when x = 1/5. What is the value of y when x = 5 ?
34kurt

Answer:

y = 1

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 25 when x = \frac{1}{5} , then

25 = \frac{k}{\frac{1}{5} } = 5k ( divide both sides by 5 )

5 = k

y = \frac{5}{x} ← equation of variation

When x = 5, then

y = \frac{5}{5} = 1

Question 14(1 point)Find the rate of change of Pete's height from 3 to 5 years.17.Time (years) 123 4 15 16Height/in.) 27 35 37 4
kupik [55]

The rate of change of Pete's height from 3 to 5 years can be determined as,

\begin{gathered} \frac{\Delta H}{\Delta t}=\frac{H_5-H_3_{}}{5-3} \\ =\frac{45-37}{2} \\ =\frac{8}{2} \\ =4 \end{gathered}

Thus, the required rate of change from 3 to 5 years is 4 in/year.
