Help, please. This is related to mirror and shadow problems
nadya68 [22]

Answer:

1. x/2=1.75/3.5  x=1

2. 4/2=y/3.5 y=3.5

3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm

A (Figure Left)=8x2-2x1-3x2=8 cm2

4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)

P (Figure Right)= 49 cm

A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)

A(Figure Right)= 24.5 cm2

Step-by-step explanation:

1. x/2=1.75/3.5  x=1

2. 4/2=y/3.5 y=3.5

3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm

A (Figure Left)=8x2-2x1-3x2=8 cm2

4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)

P (Figure Right)= 49 cm

A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)

A(Figure Right)= 24.5 cm2

Katen [24]

Answer:

10.14 feet per year.

Step-by-step explanation:

Given:

Over the next 3 1/2 years, a tree grew to a final height of 35 1/2 feet.

Question asked:

During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?

Solution:

We can find the average yearly growth rate by using average formula, taking

final height of the tree as sum of observation and time span taken to growth as number of observation:-

As we know:

Average=\frac{Sum\ of\ observation}{number \ of\ observation}

             =35\frac{1}{2} \div3\frac{1}{2} \\ \\ =\frac{71}{2} \div\frac{7}{2} \\ \\ =\frac{71}{2}\times\frac{2}{7} \\ \\ =\frac{142}{14} =10.14\ feet

Thus, during 3\frac{1}{2} \ years, the average yearly growth rate of the height of the tree was 10.14 feet per year
