B = 7/8(A-9)

first you must distribute

B =  7/8A -7 7/8

add over the -7 7/8

B + 7 7/8 = 7/8A

now divide both sides by 7/8



B+7 7/8

A rose garden Is formed by jolning a rectangle and a semicircle, as shown below. The rectangle Is 23 ft long and 14 ft wide.Find
Ratling [72]

Answer:

Area of the garden:

\begin{equation*} 398.93\text{ ft}^2 \end{equation*}

Explanation:

Given the below parameters;

Length of the rectangle(l) = 23 ft

Width of the rectangle(w) = 14 ft

Value of pi = 3.14

Since the width of the rectangle is 14 ft, so the diameter(d) of the semicircle is also 14 ft.

The radius(r) of the semicircle will now be;

r=\frac{d}{2}=\frac{14}{2}=7\text{ ft}

Let's now go ahead and determine the area of the semicircle using the below formula;

A_{sc}=\frac{\pi r^2}{2}=\frac{3.14*\left(7\right)^2}{2}=\frac{3.14*49}{2}=\frac{153.86}{2}=76.93\text{ ft}^2

Let's also determine the area of the rectangle;

A_r=l*w=23*14=322\text{ ft}^2

We can now determine the area of the garden by adding the area of the semicircle and that of the rectangle together;

\begin{gathered} Area\text{ of the garden = Area of semi circle + Area of rectangle } \\ =76.93+322 \\ =398.93\text{ ft}^2 \end{gathered}

Therefore, the area of the garden is 398.93 ft^2

Step-by-step explanation:

Given:

Allen started his homework at 8:10 p.M. And worked for 45 minutes. Then he phoned a friend and talked for 20 minutes. He went to bed when he finished the call.

Now, to find the time Allen go to bed.

Allen started his homework at 8:10 p.m.

And worked for 45 minutes.

So, to get the time when he finished homework is by adding 45 minutes and the time when he started homework:

8.10+45

=8.55\ p.m.

Thus, he finished his homework at 8:55 p.m.

Then he phoned a friend and talked for 20 minutes and went to bed when he finished the call.

<em>As, 1 hour = 60 minutes.</em>

Now, to get the time when he go to bed by adding 20 minutes and the time when he finished homework:

8.55+20=9.15\ p.m.

Therefore, Allen go to bed at 9:15 p.m.
