;-; i'm stuck again

please help

Answer:

Solution:

Given,

Radius(r) = 11 ft

C = ?

Now,

[tex]c = 2\pi \: r[/tex]

C = 2 × 3.14 × 11

= 70 cm

again,

C = 360°

angle = 315°

So,

C = 70 cm

or, 360° = 70 cm

or 1° = 70/360°

or 1° = 7/36

again ,

area = 7/36 × 315°

= 61.25 cm

Answer:

6/35

Step-by-step explanation:

3/7 : 2 1/2

2 1/2 = (2*2+1) / 2 = 5/2

3/7 : 5/2 = 3/7 * 2/5 = (3*2) / (7*5) = 6/35

Answer:

[tex]x^{2} -16x +64 = 0[/tex]

Step-by-step explanation:

[tex](x-8)^{2}[/tex] is the same as saying [tex](x-8)(x-8)[/tex]

therefore, you use FOIL(first outside inside last) to get

[tex]x^{2} -8x-8x+64[/tex]

which is [tex]x^{2} -16x +64 = 0[/tex] in standard form

Answer:

1332.8 ft^3

Step-by-step explanation:

separate the two figures into a flat cylinder and a flat box

Volume of a cylinder= [tex]\pi r^{2} h[/tex]

where radius= 3ft and height= 3ft

therefore

[tex]=\pi (3)^{2} (3) \\= 84.8 ft^{3}[/tex]

now for the flat box:

volume of box= [tex]w*l*h[/tex]

where width= 6ft, length= 16ft, height= 13ft

therefore

[tex]=(6)(16)(13)\\=1248 ft^{3}[/tex]

now add the volume of the cylinder and box together

[tex]84.8 + 1248\\= 1332.8 ft^{3}[/tex]

Answer:

Actual height  of the building [tex]=112.5[/tex] meters

Step-by-step explanation:

Given

Scale of the drawing

1 cm = 25 meters

This means that any 1 cm line on the map represents a length of 25 meters in actual.

The height of the building on map [tex]= 4.5[/tex] cm

Actual height  of the building

[tex]= 4.5 * 25\\=112.5[/tex]meters

Answer:

0 - 9 = 1

10 - 19 = 2

20 - 29 = 2

Answer:

a = 12

Step-by-step explanation:

∠OPQ is a right angle.

[tex]5^{2} + a^{2} = 13^{2} \\25 + a^{2} = 169\\a^{2} = 144\\a = 12[/tex]

Answer:

90π in^3.

Step-by-step explanation:

Total Volume = volume of cylinder + volume of the hemisphere.

= πr^2h + 1/2*4/3πr^3

= π * 3^2 * 8 + 2/3 π 3^3       ( Note the radius r = 1/2 diameter = 1/2*6 = 3)

= 72π + 18π

= 90π in^3.

Answer:

[tex]P(G\ then\ R)=0.045[/tex]

Step-by-step explanation:

From the question we are told that:

Percentage of  Green beads [tex]P_g=18[/tex]

Percentage of  Red beads    [tex]P_r=18[/tex]

Percentage of Purple beads [tex]P_p=18[/tex]

Therefore

Probability of choosing a Green bead is

 [tex]P(G)=0.18[/tex]

Probability of choosing a Red bead is

 [tex]P(R)=0.25[/tex]

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

 [tex]P(G\ then\ R)=0.18*0.25[/tex]

 [tex]P(G\ then\ R)=0.045[/tex]

Answer:

[tex]A=54.95\ ft^2[/tex]

Step-by-step explanation:

The angle of shaded sector = 360-332 = 28°

The radius of sector, r = 15 ft

We need to find the area of the shaded sector. The formula for the area of the sector is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{28}{360}\times 3.14\times (15)^2\\\\A=54.95\ ft^2[/tex]

So, the area of the shaded sector is equal to [tex]54.95\ ft^2[/tex].

The best estimate for a kitchen sink is 20 liters from the options given.

Option C is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The average capacity of a kitchen sink = 32 liters.

The best estimate for the capacity of a kitchen sink.

= 20 liters to 40 liters

Thus,

20 liters can be our best estimate.
