Answer:

56 people drink 3 cups daily

Step-by-step explanation:

What's the total number of people that drink 3 cups?

Total number of people = 400

7 / 10 were asked said yes

Number of people that said yes = (7 / 10) × 400 = 280

280 people drink tea.

20% of 280 people drink 3 cups daily, whats the number = ?

20% of 280 = ?

20 / 100 = x / 280

(20 × 280) = (100 × x)

5600 = 100x

X = 5600 / 100

X = 56 people

56 people drink 3 cups of tea daily.

Answer:

56 people drink 3 cups daily

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

We first write out $17,500 as a multiplication to 5%

New price = 17500 x 1.05 = 18375  = $18,375

18375-17500 = 875

We then work out the tax on just the mark up of $875 increase

20% mark up = 875 x 0.20 = 175

18.375+175 = 18550

= $18,550 charge to be considered for 5%

However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050

=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500

tax he paid inclusive or non inclusive would be the same.

= $3500

10% of this = 3500 x 0.10 = 350  

18550+350 = 18,900

Therefore it is not dishonest if mentioned in the terms and conditions.

We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

Answer:

Step-by-step explanation:

a.

y=0.75x

y-y1=(y2-y1)/(x2-x1)×(x-x1)

y-3=(6-3)/(8-4) (x-4)

y-3=3/4(x-4)

Step-by-step explanation:

V=πr2h=π·62·3≈339.29201

Answer:

404.09x cm³ (to 5 s.f.),

where x is the unknown height of the shape.

Step-by-step explanation:

Volume of the shape

= base area × height

= (large semicircle- small semicircle) × thickness of shape

Area of circle= [tex]\pi {r}^{2} [/tex]

Area of semicircle= [tex] \frac{1}{2} (\pi)( {r}^{2} )[/tex]

Diameter of small circle= 14

Radius= diameter ÷2

radius= 14 ÷2

radius = 7 cm

Area of small semicircle

[tex] = \frac{1}{2} (\pi)( {7}^{2} ) \\ = \frac{49}{2} \pi[/tex]

Radius of large semicircle

= 35 ÷2

= 17.5 cm

Area of large semicircle

[tex] = \frac{1}{2} (\pi)( {17.5}^{2} ) \\ = \frac{1225}{8} \pi[/tex]

Base area of shape

[tex] = \frac{1225}{8}\pi - \frac{49}{2} \pi \\ = \frac{1029}{8} \pi[/tex]

Since the height if the shape is not given, I'm afraid I cant help you find the volume.

Let the height of the shape be x cm.

Volume of shape= [tex] \frac{1029x}{8} \pi \: cm^{3} [/tex]

The area of the triangle ABC is 33 square units

We have given that,

Triangle A B C is shown. The length of A C is 16, the length of C B is 8, and the length of A B is 10.

We have to determine the area of the triangle

[tex]\text{ Area }=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

A = area

s = semi-perimeter

a = length of side a

b = length of side b

c = length of side c\text{ Area } = area

s = semi-perimeter

use the given value in the above formula we get the area of the triangle ABC is,

Therefore the correct answer is 33 square units.

Answer:

Step-by-step explanation:

N = 3rt^4 - 5rz

now factor r out

N = r(3t^4-5z)

divide by r on both sides

N/r = (3t^4 - 5z)

subtract (3t^4)

N/r - 3t^4 = -5z

now divide by -5 to isolate the variable (z)

[tex]\frac{(n/r)-3t^4}{-5}[/tex] = z

Answer:

(N-3rt^4) / -5r =  z

Step-by-step explanation:

N = 3rt^4 - 5rz

Subtract 3rt^4 from each side

N-3rt^4 = 3rt^4-3rt^4 - 5rz

N-3rt^4 =  - 5rz

Divide each side by -5r

(N-3rt^4) / -5r =  - 5rz/ -5r

(N-3rt^4) / -5r =  z

Step-by-step explanation:

Answer:

45.413 cm³

Step-by-step explanation:

Because the volume of a orament is 57 cm³ . The volume of twenty-seven oraments is 1242 cm³ . The volume of a cube is 46656 cm³

⇒The empty space is :

         46656-1242=45414 ( cm³)

                  So the empty space is 45414 cm³  

The volume of the empty space in the box, rounded to the nearest whole number, is 22,247 cubic centimeters.

It is a three-dimensional figure.

The volume of one spherical glass ornament can be found using the formula V = (4/3)πr³, where r is the radius.

We have,

V = (4/3)π(6³)

= 904.78 cm³ (rounded to two decimal places)

The volume of 27 such ornaments is:

= 27 V

= 27 × 904.78

= 24,409.06 cm³ (rounded to two decimal places)

The volume of the cube-shaped box is given by V = s³,

where s is the side length.

Substituting the given side length, we get:

V = 36³

= 46,656 cm³

The empty space in the box is the difference between the volume of the box and the volume of the 27 ornaments:

Empty space = V(box) - 27V

= 46,656 - 24,409.06

= 22,246.94 cm³

Rounding this to the nearest whole number, we get:

Empty space ≈ 22,247 cm^3

Therefore,

The volume of the empty space in the box, rounded to the nearest whole number, is 22,247 cubic centimeters.

The width of the base of the mountain defined by the function is 12 feet.

The "x" coordinate of a point, as represented on the horizontal line, is another name for the abscissa.

The co ordinate that is displayed on the vertical line, commonly known as the "y" coordinate is called ordinates.

As, 12 is written first on the co ordinates, that's why  12 is showing the abscissa on the horizontal line which is the width of the base of the mountain.
