Answer:

≈ 84.14 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a semicircle, so

A = area of rectangle + area of semicircle

   = lb + \frac{1}{2}πr²

diameter of circle = 14 - (4 + 4) = 14 - 8 = 6 , then radius r = 3

A = (14 × 5) + (0.5 × π × 3² )

   = 70 + 4.5π

   ≈ 84.14 ft² ( to the nearest hundredth )

Answer:

area of the rectangle =length *breadth

=14*5=70sq.ft

diameter =6ft

radius =3ft

area of the semi circle =1/2πr^2

=1/2*22/7*3*3=14.142sq.ft

area of the figure =area of the rectangle +area of the semi circle =70+14.142=84.142sq.ft

hi hun!

From what I understand, ill explain to the best of my knowledge so u understand!

First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.

I see that:

Flower 1: 6 inches

Flower 2: 10 inches

Flower 3: 14 inches

The proportionality which these flowers are growing at is 4 inches every two weeks.

And I also see:

Week 3

Week 5

Week 7

When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!

And also just by looking at the weeks which are 2 weeks separate if u count them.

Week 3 would be:

6/3=2

Week 5 would be:

10/5=2

Week 7 would be:

14/7=2

so the proportionality is 2! c:

What is 15/21 subtracted by 5/7 equal ?
Artemon [7]

Answer:

0

Step-by-step explanation:

<u>Step 1:  Make common denominators</u>

What is the LCM of 21 and 7:  7

So, we need to convert both fractions into a 21 denominator.

<em>15/21 * 1/1 = 15/21</em>

<em>5/7 * 3/3 = 15/21</em>

<em />

<u>Step 2:  Subtract the numbers</u>

15/21 - 5/7 is same as 15/21 - 15/21

15/21 - 15/21

<em>0</em>

<em />

Answer:  0
