Answer:

226.19 [tex]cm^{3}[/tex]

Step-by-step explanation:

Vol. of cone = Bh/3   where B is the area of the base(circle) and h is the height of the cone.

r = 3   h = 3

V = [tex]\frac{\pi *3^{2}*3 }{3}[/tex] = 9π

Vol. of the cylinder = Bh   where B is the base(circle) and h is the height of the cylinder.

r = 3   h = 10 - 3 = 7

V = [tex]\pi *3^{2} * 7[/tex] = 63π

Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19

Volume is a three-dimensional scalar quantity. The volume of the composite figure will be 226.194cm³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the composite solid is the sum of the slanted cylinder and the cone. Therefore, the volume will be,

Volume = Volume of cone + Volume of slant cylinder

             = [(1/3)πr²h] + [πr²H]

             = [(1/3)×π×(3)²×3] + [π×(3)²×7]

             = 28.274 cm³ + 197.920 cm³

             = 226.194 cm³

Hence, the volume of the composite figure will be 226.194cm³.

Answer:

43

Step-by-step explanation:

Use the mean formula:

mean = (sum of elements) / (number of elements)

Let x represent the fourth number, and solve for x:

mean = (sum of elements) / (number of elements)

40 = (35 + 41 + 41 + x) / 4

40 = (117 + x) / 4

160 = 117 + x

43 = x

So, the fourth number is 43

Answer:

You will need 411 inches

Step-by-step explanation:

To solve this problem you have to find the surface area.

First, multiply.

7 × 13 = 91

16 × 7 = 112

16 × 13 = 208

Then add.

91 + 112 + 208 = 411

You will need 411 inches of wrapping paper to cover the box.

Answer: 12 boys attend Millwood School.

Step-by-step explanation:

Yeah. It just makes sense. I am bad at explaining. Sorry!

The ratio shows how many times one value is contained in another value.

The ratio of boys to girls at the Milwood School is 4 to 5.

The number of girls that attended the Milwood school is 15.

The number of boys that attended the Milwood school is 12.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of boys to girls at the Milwood School is 4 to 5.

Total number of children = 27

Let the number of boys = 4x

Let the number of girls = 5x

Now,

4x + 5x = 27

9x = 27

x = 3

Now,

The number of boys = 4x = 4 x 3 = 12

The number of girls = 5x = 5 x 3 = 15

Thus,

The number of boys that attended the Milwood school is 12.

Answer:

22°

Step-by-step explanation:

Okay, to first find the missing side, you need to use a² +b² = c²

getting 21.54 for the hypotenuse. From there, you're going to divide the leg (8) that's opposite of the angle you're trying to find and divide it by the hypotenuse (21.54).

Answer:

57.12 cm²

Step-by-step explanation:

area = (9.28 + 5) × 8/2

= 14.28 × 4 = 57.12 cm²

Answer:

24.27 cm

Step-by-step explanation:

sin 65 degrees = 22/x, so:

      1                   x

------------------ = ------

 sin 65 deg       22

so x = 22 / (sin 65 deg) = 22/0.906 = 24.27 cm

25 = a1(1- (0.6)⁴)/(1-0.6)

25 = a1 (1- 0.13)/(0.4)

10 = a1(0.87)

a1 = 11.49

S8 = 11.49(1- (0.6)^8)/(1-0.6)

= 11.49(1-0.017)(1-0.6)

= 11.49(0.983)/0.4

= 28.24

The sum of the first eight terms of the given geometric series is; 28.24

We are told that the sum of the first four terms of the geometric series is 25. Thus, formula for sum of n terms of a geometric series is;

Sₙ = a(1 - rⁿ)/(1 - r)

where;

a is first term

r is common ratio

Thus;

25 = a(1 - (0.6)⁴)/(1 - 0.6)

25 = a(1 - 0.13)/(0.4)

10 = 0.87a

a = 11.49

Thus, sum of the first 8 terms of the series is;

S₈ = 11.49(1 - 0.6⁸)/(1 - 0.6)

S₈ = 11.49(1 - 0.017)(1 - 0.6)

S₈ = 28.24

Answer: (3x-5)(x+3)(x-3)

Step-by-step explanation:

Answer:

13 / 25 were boys

14 / 25 were girls

Step-by-step explanation:

Of the girls 10 said no and 4 said yes

10 + 4 = 14 so she asked a total of 14 girls

Of the boys 8 said yes and 5 said no

8 + 5 = 13 so she asked a total of 13 boys

she asked 14 girls and 13 boys

14 + 13 = 25 so she asked a total of 25 people

Out of the 25 people she asked 13 of them were boys

So 13 out of 25 people we boys

or 13 / 25

which means 14 out of 25 were girls

or 14 / 25

Answer:

Step-by-step explanation:

simplify upper n lower fraction of LHS:

2^x+22^x+222^x

= 2^x*1 + (2*11)^x + (2*111)^x

= 2^x*1 + 2^x*11^x + 2^x*111^x

= 2^x*(1+11^x+111^x)

3^x+33^x+333^x

= 3^x*1 + (3*11)^x + (3*111)^x

= 3^x*1 + 3^x*11^x + 3^x*111^x

= 3^x*(1+11^x+111^x)

so LHS

= 2^x*(1+11^x+111^x) / (3^x*(1+11^x+111^x))

= 2^x / 3^x

= (2/3)^x

RHS = 9/4

= (3^2/ 2^2)

= (3/2)^2

= (2/3)^(-2)

so x = -2
