Answer:

2.24

Step-by-step explanation:

Well...Ummm I don't know how to exactly explain it but I'll try

11 x 2.24=24.64 or you can do division and do 24.64 divided by 2.24=24.64

To see which option is the most accurate one, we will verify all the options to see which is correct.

Option A (Correct/Incorrect)

Option A (Reasoning):

In this step, we can see that 3/4 was added to both sides. This can only mean that the property used here is the Addition property of Equality.

Option B (Correct/Incorrect)

Option B (Reasoning):

In this step, subtraction has not been used. It has been clearly stated that 3/4 was added to both sides.

Option C (Correct/Incorrect)

Option C (Reasoning):

In this step, multiplication has not been used. It has been clearly stated that 3/4 was added to both sides.

Option D (Correct/Incorrect)

Option D (Reasoning):

In this step, division has not been used. It has been clearly stated that 3/4 was added to both sides.

Option A is correct.

Addition property of equality is  applied in the first step of equation x/4-3/4=16.

Two or more expressions with an Equal sign is called as Equation.

The given equation is x/4-3/4=16

x divided by four minus three divided by four equal to sixteen.

The first step to solve this equation as

x/4-3/4+3/4=16+3/4

Which means we have added 3/4 on both sides of the equation.

As per the addition property of equality, when we add the same number to both sides of an equation then the two sides remain equal.

So we have used the  addition property of equality

Hence,  addition property of equality is  applied in the first step of equation x/4-3/4=16.

Alex needs a score of about 70 to be in the top 20% of the distribution

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ)/σ

Where x is raw score, μ is mean and σ is standard deviation.

Given that μ = 62, σ = 6, z = 1.28, hence:

1.28 = (x - 62) / 6

x = 69.68

Given :difference between 2 whole number = 66ratio of the 2 whole number =2:5Let:1 whole number be 2x2 whole number be 5xA/Q

difference between 2 whole number = 66

Let's turn it into algebraic equation:

5x - 2x = 663x= 66x =66 /3x =22

Now Let's put value of x to find two whole numbers

[tex]y=\dfrac49x[/tex]

Step-by-step explanation:

Let [tex](x_1,y_1)[/tex] = (45, 20)

Let [tex](x_2,y_2)[/tex] = (72, 32)

using slope formula to find slope [tex]m[/tex]:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{32-20}{72-45}=\dfrac49[/tex]

using point-slope formula:

 [tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-20=\dfrac49(x-45)[/tex]

[tex]\implies y-20=\dfrac49x-20[/tex]

Answer:

let the angle be x

Step-by-step explanation:

then,

angle1=2x

angle2=4x

angle3=9x

sum of all angles i  triangle is 180

then

2x+4x+9x=180

15x=180

x=12

angle1=2*12=24

angle2=4*12=48

angle3=9*12=108

Answer: w = 9

Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.

18 + 4w = 6w

4w + 18 = 6w

Now we subtract 18 from both sides.

When we simplify, we get that w = 9.

Step-by-step explanation:

Hope this helps =)

Answer:

w = 9

Step-by-step explanation:

Rearrange terms

4w + 18 = 6w

Subtract 18 from both sides of the equation

4w+18-18 = 6w -18

Simplify

4w=6w-18

Subtract 6w from both sides of the equation

4w-6w=6w-18-6w

Simplify

-2w=-18

Divide both sides of the equation by the same term

-2w = -18/-2

Simplify

w = 9

Answer:

About 718.0133  cm³

Step-by-step explanation:

The crucial part is to take V=4/3πr³ and multiply that by 1/2 (or divide by 2) This is because it is asking for half a sphere, which represents a bowl.

You plug in your values, which will look like: (1/2)(4/3)π(7)³. (Remember to insert 7 not 14 since it's asking for radius).

________________________________________________________

7 cubed is 343,

343 * 2/3 is about 228.66

228.66 times 3.14 is about 718.0133

-> or just 718 cm³

By taking the product of the two fractions we will see that the number that goes in the green box is a 6.

We only can add two fractions if we have the same denominator in both of them, here we want to transform -2/3 in an equivalent fraction, such that the denominator is 9, so we multiply both the numerator and denominator by 3.

So we need to solve:

[tex]\frac{-2}{3}*\frac{3}{3} = \frac{-2*3}{3*3} = \frac{-6}{9}[/tex]

From that, we can conclude that the number that goes in the green box is 6.

Answer:

130 cents, or $1.30.

Step-by-step explanation:

To find the total cost of the meal, add the costs of each product.

Since the cost of the sandwich was 80 cents, the cost of the milk was 20 cents and the cost of the pie was 30 cents, then the total cost of the meal (in cents) is:

[tex]80+20+30[/tex]

Add the numbers from left to right. Since 80+20 is equal to 100, then:

[tex]80+20+30=100+30[/tex]

Finally, notice that 100+30 is equal to 130:

[tex]100+30=130[/tex]

So, the total cost of the meal was 130 cents. Each 100 cents is equal to 1 dollar. Then, 130 cents is the same as $1.30.

Therefore, the cost of the meal was 130 cents, or $1.30.

Answer:

The dimension of the room is Length of 5m and Width of 8m

Step-by-step explanation:

Formula for perimeter of a rectangle is;

P = 2(L + W)

Where;

L is length

W is width

We are given;

Width; W = 1.6L

Perimeter; P = 26 m

Thus;

2(1.6L + L) = 26

2(2.6L) = 26

5.2L = 26

L = 26/5.2

L = 5 m

W = 1.6 * 5

W = 8 m
