Answer:

729

Step-by-step explanation:

Each side of the cube measures 9cm

The volume of a cube is V^3

Therefore the volume can be calculated as follows

= 9^3

= 729

Hence the volume is 729

Answer:

[tex]\huge\boxed{\sf x = 6 + 2y}[/tex]

Step-by-step explanation:

Let the total cost be x and number of rides be y

It costs $2 on each ride. So, the rides' cost will be:

=> Number of rides * One rides' cost

=> y * 2

=> 2 y

So, The total cost will be:

Total cost = Entrance cost + Rides' cost

Total cost = $6 + $2(Number of rides)

x = 6 + 2y

Answer:

x = 13, y = 7

Step-by-step explanation:

The diagonals of a parallelogram bisect each other , so

x - 7 = 6 ( add 7 to both sides )

x = 13

and

2y - 6 = 8 ( add 6 to both sides )

2y = 14 ( divide both sides by 2 )

y = 7

The function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a primary function:

f(x) = sinx     and

The transformed function is:

[tex]\rm g(x) = sin(x+\frac{{\pi} }{3} )[/tex]

If we replace x to [tex]\rm x + \frac{\pi}{3}[/tex] it will shift to the left by π/3 units.

For a period of the transformed function is given by:

[tex]\rm T = \frac{2\pi}{n}[/tex]

Where n is used to find the period of the function.

n = 1

t = 2π

Thus, the function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π

Answer:

60

Step-by-step explanation:

To find the area of a triangle, multiply the base and height, then divide by two

The center triangle's area is (5*6)/2, which is also 15.

Since all the triangles are congruent, multiply 15 by 4 to get the total surface area, which is 60

Step-by-step explanation:

move decimal over to the left twice

Given:

A fruit salad recipe calls for [tex]\dfrac{3}{4}[/tex] pound of apples and [tex]\dfrac{2}{5}[/tex] pound of dates.

To find:

The least common denominator of the fractions.

Solution:

The given fractions are:

[tex]\dfrac{3}{4}[/tex] and [tex]\dfrac{2}{5}[/tex]

The denominators of these fractions are 4 and 5 respectively.

Factor form of 4 is 2×2.

5 is a prime number, so factor form of 5 is 5×1.

Now, the least common denominator of the fractions is:

[tex]LCD=2\times 2\times 5[/tex]

[tex]LCD=20[/tex]

Therefore, the least common denominator of the fractions is 20.

Answer:

13

Step-by-step explanation:

Given the expression;

2 1/3 : 4 1/3 = 7 : x

Wea re to look for x;

Convert to improper fractions;

7/3 : 13/3 = 7:x

7/3 * 3/13 = 7/x

7/13 = 7/x

Cross multiply

7x = 13 * 7

7x = 91

x = 91/7

x = 13

Hence the unknown value is 13

Answer:

432 ft²

Step-by-step explanation:

First lets find radius (r);

r = d/2

r = 24/2

r = 12

Now let's find the area;

A = π(12)²

A = 3(144)

A = 432 ft²

Answer: You will pay 102Ghana cedis

Step-by-step explanation:

a pencil cells at 18 Ghana cedis

Three pencils will cost 3 x 18Ghana cedis=54 Ghana cedis

Also an eraser class at 12 Ghana cedis

Four erasers will cost 4 x 12 =48Ghana cedis

Total amount for three pencils and for erasers =54 Ghana cedis+48Ghana cedis=102Ghana cedis.

Answer:

Kirsten travels 7.5 miles to go to work.

Step-by-step explanation:

Bike: 10 MPH

Time: 1/4 Hour

1/4 of 10 = 2.5

Distance travelled on bike: 2.5 miles

Train: 20 MPH

Time: 1/4 Hour

1/4 of 20 = 5

Distance travelled by train: 5 miles

Add the distances together.

5 + 2.5 = 7.5

7.5 miles
