2) Find the area and perimeter of a semi -circular disc whose radius is 10cm. (take π = 3.14)

SVETLANKA909090 [29]

Answer:

=3.14×10x10

=3.14×100cm2

=3.14cm2

<h3>Perimeter = 2 pi r</h3>

=2 ×3.14×10

=6.28cm

Or =Pi d

= 3.14 ×20cm

=62.8cm

R means radius

D means diameter

radius is half of a diameter e.g radius is10 and diameter is 20

Question # 4

nadezda [96]

Ages of Mark, Brett and Carl are 80 years, 60 years and 70 years respectively.

<u>Solution:</u>

Given that

Brett is 18 years younger than Mark.

Carl is 10 years younger than Mark.

The sum of the ages of Brett, Mark, and Carl is 212

Need to determine age of Brett, Mark, and Carl.

Let assume age of mark in years be represented by variable x

As it is given that Brett is 18 years younger than Mark , so if we subtract 18 from the age of Mark we will get age of Brett ,

=> Age of Brett = x – 18

Also given that Carl is 10 years younger than Mark , so if we subtract 10 from the age of Mark we will get age of Carl ,

=> Age of Carl = x – 10

Given sum of ages of Brett, Mark, and Carl is 212

=> Age of Mark + Age of Brett + Age of Carl = 212

=> x + ( x – 18 ) + ( x – 10) = 212

=> 3x – 28 = 212

=> 3x = 212 + 28

Age of Mark = x = 80 years

Age of Brett = x – 18 = 80 – 18 = 62 years

Age of Carl = x – 10 = 80 – 10 = 70 years

Hence Ages of Mark , Brett and Carl are 80 years, 60 years and 70 years respectively.

What is Steven’s slugging average if his stats are- Show steps. 25 singles 10 doubles 3 triples 10 homeruns 140 at-bats

kap26 [50]

<h2>Hello!</h2>

The answer is:

The correct answer is c.

$SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671$

To calculate the slugging average or slugging percentage, we need to divide the number of total bases by the total times at bat.

$SluggingAverage=\frac{TotalBases}{TimesAtBat}$

We know that:

A single means 1 base.

A double means 2 bases.

A triple means 3 bases.

A homerun means 4 bases.

So, we know that:

$Singles=25=25bases\\Doubles=2*10=20bases\\Triples=3*3=9bases\\Homeruns=10*40=40bases\\TimesAtBat=140$

Then, substituting and calculating we have:

$SluggingAverage=\frac{25bases+20bases+9bases+40bases}{140}$

$SluggingAverage=\frac{94bases}{140times}=0.671$

Hence, the correct answer is c.

$SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671$

Have a nice day!
