Answer:

Step-by-step explanation:

( 5 - x) ( 4-x )

=5(4-x)-x(4-x)

=20-5x-4x+x^2

=x^2-9x+20

Multiply first two values in brackets:

5 x 4 = 20

Multiply the outside values in the brackets:

-x * 5 = -5x

Multiply the inside terms:

-x * 4 = -4x

Multiply the last terms:

-x * -x = x^2

Place all values together:

x^2 - 5x - 4x + 20

Simplify it:

x^2 -9x + 20

Step-by-step explanation:

When equal bases are multiplied, the powers add.

The bases of both expressions is x.

The powers are 5 and 7.

The answer is x^(5 + 7) = x^(12)

Answer:

The customer can form 160 different kits in the perfumery

Step-by-step explanation:

Here, we are interested in knowing the number of different kits a customer can form in the perfumery.

Now since each kit contains 1 each of moisturizers, soaps and perfume, what will happen is that we are going to select one each of the options

This means we shall be selecting 1 out of 5 soaps, 1 out of 8 moisturizer and 1 out of 4 perfumes

Mathematically, the number of ways we can select r items out of a total of n can be calculated as nCr

Applying this in the case we have;

It would be;

8C1 * 5C1 * 4C1

where

8C1 = 8, 5C1 = 5 and 4C1 = 4

Thus the number of options we have will be

= 8 * 5 * 4 = 40 * 4 = 160 kits

Responda:

O cliente pode formar 160 kits diferentes na perfumaria

Explicacao/etapas:

= 8 * 5 * 4 = 40 * 4 = 160 kits

espero que tenha ajudado! :) ......... tchau!

Step-by-step explanation:

A PERSON HEIGHT IS NOT ZERO WHEN BORN

Answer:

  890.1 cm^3

Step-by-step explanation:

The volume of the cylinder is given by the formula ...

  V =  πr^2h

Filling in the given numbers, we find the volume of the cylinder to be ...

  V = π(5 cm)^2(8 cm) = 200π cm^3

__

The volume of a hemisphere is given by the formula ...

  V = (2/3)πr^3

Filling in the given radius, we find the hemisphere volume to be ...

  V = (2/3)π(5 cm)^3 = 250π/3 cm^3

__

The total volume of the toy is presumed to be the sum of these volumes, so is ...

  toy volume = (200π cm^3 +250π/3 cm^3) = 850π/3 cm^3

  toy volume ≈ 890.1 cm^3

Answer:

Scalene, Acute

Step-by-step explanation:

Answer:

1^3 cubic feet

Step-by-step explanation:

Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

We get the final answer of -4x + 6

Step-by-step explanation:

Let's simplify step-by-step.

2x −3(2x−2)

Distribute:

= 2x+ (−3)(2x) + (−3)(−2)

= 2x+ −6x + 6

Combine Like Terms:

= 2x + −6x + 6

= (2x + −6x) + (6)

= -4x + 6

Answer:

60°

Step-by-step explanation:

90+30=120°

180-120=60°

Step-by-step explanation:

all sides of a triangle = 180

all sides of a triangle = 180

So 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x

so equation forms like

180 = 90+30+x

180 =120+x

180-120 =x

60 =x

SO THE ANSWER WILL BE 60°

HOPE IT WILL HELP YOU ☺️

If a² + b² = c², then the triangle is right.

So we have (8)² + (11)²  ?  (13)²

(8)² is 64, (11)² is 121, and (13)² is 169.

So we have 64 + 121 ? 169

64 + 121 is 185 and we can see that 185 > 169.

This triangle would not be a right triangle.

In fact, it would be an acute triangle.

So no, it's not a right triangle.

Answer: b infinite number of solutions (blue and purple)

Step-by-step explanation:

There will be multiple solution for both inequality.

Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.

According to the question

y<3/2x-2      ---------- (1)    

y<3/2x -8    -----------(2)

to take out points we have to take (1) as  y= 3/2x-2

x y

-4 -8

-2 -5

0 -2

2 1

4 4

6 7

same for (2) we take  y=3/2x -8

x  y

-2 -11

0 -8

2 -5

4 -2

6 1

Then we plot our graph which is shown in sheet attached

According to the graph we can see that they both are parallel to each other now we will shade left hand side of line as per the inequality

when we shade we will observe that points left side of equation (2) are common in both  .

Hence, there will be multiple solution .

Answer:

Step-by-step explanation:

The volume formula for a cylinder is

[tex]V=\pi r^2h[/tex]

In order to find the radius we need to use the circumference we were given. The formula for the circumference is

[tex]C=2\pi r[/tex]

Filling in the info about the circumference value of 87.92:

[tex]87.92=2(3.14)r[/tex] or

87.92 = 6.28r so

r = 14

Now that we know the radius we can fill in the volume formula:

[tex]V=(3.14)(14)^2(160)[/tex] and

V = 98470.4 cm cubed

Answer:

the answer is y = x-5
