Answer:

Step-by-step explanation:

-18 divided by -9 is +2 and that is what you want.

-18 divided by 2 is -9, not correct.

-12 divided by (-3) is +4, not correct.

-10 divided by 5 is -2, not correct.

Leaving the correct answer: -8 divided by (-4) is +2.

Answer: (c - 3) / 2 = x

Step-by-step explanation:

If c represents the cookies, then you remove 3 because she ate 3 of the cookies. Since half of the remainder of the cookies were given to her friend, you must divide the product of c - 3, by 2. The reason for the parenthesis is so that it overrules PEMDAS, as parenthesis goes before division.

Answer:

339.3 cm^3

Step-by-step explanation:

V=πr2h=π·62·3≈339.29201

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.

B The highest point of the mountain is defined by the function is 16 feet.

Step-by-step explanation:

The points (12, 16) can be explained as,

The highest point of the mountain defined by the function is 16 feet.

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

a group of variables that accurately depict a position. The first number on a graph represents the distance along, while the second number represents the distance up or down. For instance, the point (2,15) is located 2 units down and 15 units up.

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.

While, 16 here shows the ordinates on the vertical line which is the highest point of the mountain.

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,

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:

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
