Answer:

Yellow = 2/3(Blue)

Step-by-step explanation:

You only really need the first row of the table since it shows the volume of yellow to the volume of blue.

Before we write the equation we have to find the ratio and to do that we divide.

Divide the amount of yellow by the amount of blue:

3.5/ 5.25 = 0.666 = 2/3

now we can write the eqaution:

Yellow = 2/3(Blue)

Answer:

[1] -2 2/3 + (-3 1/6)  [2] -2.2*3.4  [3]  4.2/-6  [4]   -3 3/5 - (-3 1/10)

Step-by-step explanation:

[1] = -5.91666

[2] = -7.48

[3] = -0.7

[4] = -0.5

Number 1 is Rio Grande and number 2 is St. Lawrence River

Step-by-step explanation:

Answer:

First, find the area for the kitchen floor: 16.5*15=247.5 squared feet

Then find the area for one tile: 0.5*0.5=0.25 squared feet

Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.

Also you can do it in this another way:

First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33

Then, do the same for the height: 15/0.5=30

Finally multyply both results: 33*30= 990 tiles.

Step-by-step explanation:

or just 990

Answer:

n + 3m + 2, or also the same as 1n + 3m + 2

The simplified form of the given expression is [tex]n+2+3m[/tex].

Important information:

[tex]a(b+c)=ab+ac[/tex]

We have,

[tex]\dfrac{1}{2}(2n+4+6m)[/tex]

Using the Distributive Property, the given expression can be written as:

[tex]=\dfrac{1}{2}(2n)+\dfrac{1}{2}(4)+\dfrac{1}{2}(6m)[/tex]

[tex]=n+2+3m[/tex]

Thus, the simplified form of the given expression is [tex]n+2+3m[/tex].

Answer:

m=-1

slope=-1

Step-by-step explanation:

The complete steps are;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or variable raised to the power one.

We have to given some steps of equation.

Now, The complete steps to solve the equation are;

1/5t + 2 - ____ = 17 - _____

Subtract 2 from both sides;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

Multiply 5 in both sides;

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

So, The complete steps are;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

Answer:

sorry if this is wrong

Step-by-step explanation:

 Maggie = X

Brother = 2X-3 <--- 3 years younger than twice her age.

2x - 3 + x = 24  <--- the sum of their ages is 24

3x - 3 = 24

3x = 27

x = 9

Maggie is 9.

Brother is 2*9 - 3 = 18 - 3 = 15

Step-by-step explanation:

Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Total number of ergs produced can be calculated thus :

[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]

Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate
