16)<br> A rectangular swimming pool measures 5 1/2 meters by 3 1/2 meters What<br> is the perimeter?
KIM [24]

Answer:

18 m

Step-by-step explanation:

Perimeter is the sum of all the sides.

A rectangular pool has two sides at 5 1/2 m and two sides at 3 1/2 meters.

Add the whole numbers, then add the halves. Now ad the two parts together.

5 1/2 + 3 1/2 + 5 1/2 + 3 1/2 = 16 + 2 = 18 m

Can someone please help me with this is area of circles
vivado [14]
<h3><u>Given Information :</u></h3>

  • Radius of the turbine = 32 m
  • π = 3
<h3 /><h3><u>To calculate :</u></h3>

  • Area covered by blade when the turbine makes 1 revolution.

<h3><u>Calculation :</u></h3>

We know that,

\bigstar \: \boxed{\sf {Area_{(Circle)} = \pi r^2}} \\

\sf \longmapsto {Area = \{3 \times (32)^2 \} \: m^2 }

\sf \longmapsto {Area = \{3 \times 1024 \} \: m^2 }

\longmapsto \sf \red  {Area = 3072 \: m^2 }

Therefore,

  • Correct option is <u>option 4th.</u>

How much water do you add to make 12% sugar syrup using 5g sugar.
stealth61 [152]

Answer:

so the syrup is just water and sugar, we know that the sugar percent is just 12%, and that happens to be 5grams.

now 100% - 12% is 88%, so the 88% leftover will just be water.

if 12% is 5g, how much is 88%?
