Amy has three times as many Star Wars toys as Carly. Total they have 160 Star Wars toys. How many Star Wars toys does Amy have?

**Answer:**

53

**Step-by-step explanation:**

**Amy** has 120 star war **toys**.

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,

**Amy**:

Number of toys = 3x

**Carly**:

Number of toys = x

Now,

In **total**, they have 160 Star Wars **toys**.

So,

x + 3x = 160

4x = 160

x = 40

Now,

3x = 3 x 40 = 120

x = 40.

Thus,

**Amy** has 120 **toys**.

Carly has 40 toys.

a block of wood has a mass of 3.5 kilogram. the wood has density 0.065 kg/m3

work out the volume of the block of wood

**Step-by-step explanation:**

A block of wood has a mass of 3.5 kilogram. The wood has density 0.065 kg/m³.And we need to find out the volume of the wood. Density , volume and mass are related as ,

Density :-

Mass per unit Volume .[tex]\implies\rm Density =\dfrac{Mass}{Volume}[/tex]

Substitute the respective values :-

[tex]\implies\rm Density =\dfrac{Mass}{Volume}\\\\\rm\implies 0.065 kg/m^3=\dfrac{3.5kg}{V}\\\\\rm\implies Volume = \dfrac{3.5kg}{0.065 kg/m^3}\\\\\implies\boxed{\red{\rm Volume = 53.84 m^3}}[/tex]

Answer:

0.0000024

Step-by-step explanation:

10^-6 = 0.000001

2.4 * 10^-6 = 2.4 * 0.000001

2.4 * 10^-6 = 0.0000024

Hence, in standard form : 0.0000024

Which number completes the table for y = x^2?

a.) -9

b.) 9

c.) 6

d.) -6

**Answer:**

B

**Step-by-step explanation:**

We can substitute the x value given, -3, into our equation, y = x^2, to get what the y would be:

y = x^2

y = (-3)^2

When a negative number is squared, it is positive, so (-3)^2 = 9, and:

y = 9

This is option b

Answer:

B) 9

Step-by-step explanation:

We are given the equation y = x^2 for the table, and a x value.

To find the y value that corresponds to that x value, we must plug the x value in the equation.

Y =x^2

Y= -3^2

Y=9

Create an equivalent expression without parentheses.

**Answer:**

-0.55n - 0.05

**Step-by-step explanation:**

You can start by distributing:

(0.25n - 0.3) - (0.8n - 0.25)

0.25n - 0.3 - 0.8n + 0.25

Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)

**-0.55n - 0.05**

**Answer:**

**-0.55n - 0.05**

**Step-by-step explanation:**

(0.25n - 0.3) – (0.8n - 0.25)

When subtracting the signs change

0.25n - 0.3 - 0.8n + 0.25

Regroup like terms

0.25n - 0.8n - 0.3 + .25

What single transformation was applied to triangle A to get triangle B? Links will be reported

**Answer:**

Rotation:

**Step-by-step explanation:**

Translation is usually movements like up, down, left, right.

Dilation is when one shape is bigger/smaller than the other, but still congruent.

Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

Find the circumference of a circle with diameter 2 cm. Use 3.14 for

Given,

Diameter = 2 cm

pi = 3.14

To find : Circumference ( circle ) = ?

Radius ( r )

= Diameter / 2

= 2 / 2

= 1 cm

Formula : -

Circumference ( circle ) = 2 pi r

2 pi 4

= 2 × 3.14 × 1
