Answer:

<u>Each</u><u> </u><u>box</u><u> </u><u>is</u><u> </u><u>1</u><u>/</u><u>5</u><u> </u><u>metres</u><u> </u><u>or</u><u> </u><u>0</u><u>.</u><u>2</u><u> </u><u>metres</u><u> </u><u>deep</u><u>.</u>

Step-by-step explanation:

There are 15 boxes, total height is 3 meters

Depth of each box:

15 \: boxes = 3 \: meters \\ 1 \: box =  \{ \frac{(1 \times 3)}{15}  \} \: meters \\  \\  =  \frac{3}{15}  \: m \\  \\  { \boxed{ \boxed{=  \frac{1}{5}  \: metres}}} \:  \: or \:  \: { \boxed{ \boxed{ = 0.2 \: m}}}

Michael received a grant to make a community garden. He makes a scale drawing of his vision for the garden. Michael's drawing sh
Mila [183]

Step-by-step explanation:

Find the diagram to the question attached.

From the diagram, we are given the following dimension for one of the beds;

Length = 16cm

Width = 8cm

If the scale from his drawing to the actual garden is 2 cm for every 1 ft, then on converting to feet;

2cm = 1ft

16cm = x fr

cross multiply

2x = 16

x = 8ft

Hence 16cm = 8ft (based on the scale)

Similarly:

2cm = 1ft

8cm = x fr

cross multiply

2x = 8

x = 4ft

Area of the garden bed (in feet) = Length * Width

Area of the garden bed = 8ft * 4ft

Area of the garden bed = 32ft²

Hence the actual area of one of the garden beds is 32ft². We need to find 2 things fir us to get the required answer. First is the length of the bed in feet and the second is the width of the bed in feet.

<h3>Answer:  9 meters</h3>

===========================================

Work Shown:

  • side a = 8
  • side b = 5
  • angle C = 88 degrees

Applying the law of cosines

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 8^2 + 5^2 - 2*8*5*cos(88)

c^2 = 64 + 25 - 80*cos(88)

c^2 = 86.2080403

c = sqrt(86.2080403)

c = 9.2848285

c = 9

Technically he needs 10 meters of rope because of the extra 0.28 portion, but I'll stick with 9 meters since your teacher said to round to the nearest whole number.

Write the decimal as a percent of 0.768
Nikitich [7]

To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.768 × 100 = 76.8%

The ease way:

1) Move the decimal point two places to the right: 0.768 → 7.68 → 76.8.

2) Add a % sign: 76.8%

"<u>Answer: 76.8%"</u>

Hope this helps!

Thanks!
