We are given that

20%

When we change percent into fraction we will divide the percent by 100

[tex]\frac{20}{100}=\frac{1}{5}[/tex]

[tex]\frac{1}{3}[/tex]

[tex]\frac{2}{3}[/tex]

[tex]\frac{1\times 5}{3\times 5}=\frac{5}{15}[/tex]

Answer:

12.8mph

Step-by-step explanation:

Let 'w' represent her walking speed

->if her jogging speed is 8mph faster than her walking speed

Jogging speed=  w+8

Using the time equation i.e time = dist/speed

For walking when distance is 8miles

time = dist / speed= 8/w hrs

For jogging when distance is 13miles

time = dist / speed= 13/(w+8) hrs

Equating the time

jog time = walk time

13/(w+8) = 8/w

By cross multiplying it

13w = 8w + 64

5w = 64

w=64/5

w=12.8mph

Therefore, 12.8mph is her walking speed.

Answer:

|x - 1| = 6

Step-by-step explanation:

After step 2, we have that:

(x - 1)^2 = 36

and after step 4, we have the results:

x = -5 or x = 7

After step 2, what we can do in step 3 is: use square root in both sides of the equation:

|x - 1| = 6

This equation can be split in two:

x - 1 = 6 -> x = 7

x - 1 = -6 -> x = -5

So Seth could write this equation in step 3:

|x - 1| = 6

The value of x from the given expression are 5 and 7

Given the expression

5(x - 1)^2 = 18

Step 2 as shown is given as:

(x - 1)^2 = 36

Take the square root of both sides

√(x - 1)^2 = √36

x - 1 = 6

The solutions are x - 1 = 6 and x + 1  = 6

x = 6 + 1 = 7

x = 6 - 1

x = 5

Hence the value of x from the given expression are 5 and 7

Step-by-step explanation:

Answer: 7 hours to make $154.

Step-by-step explanation: First we want to know how much Dan makes in 1 hour of work. To do this simply divide 242 by 11. 242/11 = 22, or $22 per hour of work.

T find how many hours he would have to work to make $154, simply divide 154 by 22. 154/22 = 7, or 7 hours of work.

So, Dan will have to work 7 hours to make $154.

Final answer:

Dan earns $22 per hour, so to make $154, he would need to work for 7 hours at that same rate.

Explanation:

Dan made $242 for 11 hours of work. To calculate the rate of pay per hour, we would divide $242 by 11 hours, which gives us a rate of $22 per hour. The question asks how many hours Dan would need to work to make $154 at the same rate. To find this, we divide $154 by the hourly rate of $22.

$154 ÷ $22 per hour = 7 hours

Therefore, Dan would have to work for 7 hours to make $154 at the same rate of pay.

[tex]a=4.1-4.5=-0.4\\b=7.2-7.05=0.15[/tex]

The values of a and b are,

⇒ a = -0.4 and b = 0.15

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.

i.e. Residual value = given value - predicted value

From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.

Therefore, We get;

a = 4.1 - 4.5

a = -0.4

Similarly, the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.

Therefore, We get;

b = 7.2 - 7.05

b = 0.15

Therefore, a = -0.4 and b = 0.15

It's okay to be a little lost. When I have exponents and all this "fun" stuff, I use Desmos graphing calculator. It will help you GREATLY. Let me know if you wan the link...

The length of 'w' is approximately 73 cm.

To find the length of 'w,' we can use the Pythagorean Theorem since 'w' is the hypotenuse of a right triangle with legs 'x' and 'y.' The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs. So, we have:

w^2 = x^2 + y^2

Substituting the given values, we get:

w^2 = 48^2 + 55^2

w^2 = 2304 + 3025

w^2 = 5329

Taking the square root of both sides, we find:

w = √5329

w ≈ 73 cm

Final answer:

After performing the calculations, the hypotenuse w is found to be 73 cm, which corresponds to option D.

Explanation:

To find the length of w, which is the hypotenuse of the right-angled triangle with sides x = 48 cm and y = 55 cm, we use the Pythagorean theorem.

This theorem states that in a right triangle, the square of the length of the hypotenuse (w) is equal to the sum of the squares of the lengths of the other two sides (x and y).

According to the theorem:

w² = x² + y²

Plugging in the given values:

w² = 482 + 552

w² = 2304 + 3025

w² = 5329

To find w, we take the square root of both sides:

w = √5329

w = 73 cm

Therefore, the length of w is 73 cm, which corresponds to option D.

Answer:

units

Step-by-step explanation:

I had this question on flocabulary.

We divide the number line into intervals to understand how far we need to move left or right when solving equations. This division into intervals creates a physical representation that helps visualize calculations and absolute differences between numbers.

We divide the number line into intervals so we know how far to move left or right when doing equations. For understanding, let's consider an example. If we're working with whole numbers and the number line is divided into single-unit intervals, moving to the right from 0 to 5 means we've added 5 to our original number. Similarly, moving to the left of 0 to -5 means we've subtracted 5 from our original number.

The division of the number line helps to visualize the calculation process and see physical representation of absolute differences between numbers. For example, if we make the distance between each interval equal to one unit, the distance between 1 and 3 on the number line is 2 units, which corresponds to the absolute difference between these numbers.

Answer:

$100.647

Step-by-step explanation:

Diameter = 45ft

Radius = diameter / 2 = 45 / 2 = 22.5ft.

1 gallon of paint covers 300ft²

1 gallon cost $18.99

The total area of the mural = πr² (since it's circular and area of a circle = πr²)

Area = πr²

Area = 3.14 * (22.5)²

Area = 1589.625ft²

The total area of the mural = 1589.625ft²

1 gallon of paint covers 300ft²

X gallons of paint will cover 1589.625ft²

Making x the subject by cross multiplying

X = (1 * 1589.625) / 300

X = 5.29875 gallons.

5.3 gallons will be required to paint 1589.625ft²

But 1 gallon costs = $18.99

5.3 gallons will cost $ y

y = (5.3 * 18.99) / 1

y = $100.647

Damari will spend $100.647 to paint the mural.

Answer:

Step-by-step explanation:

Given that the two equations -3x + 6 = 21  and -3x + 6 <21

From the given equations -3x + 6 = 21  and -3x + 6 <21 we have that

-3x+6-6=21-6

-3x=15

[tex]x=-\frac{15}{3}[/tex]

-3x + 6 <21

-3x+6-6<21-6

-3x<15

[tex]x< -\frac{15}{3}[/tex]

The first equation is a statement of equality, while the second is an inequality. The process is solving equations and inequalities.

The process used to solve the equations involves identifying whether the given expressions are equations or inequalities and then applying appropriate techniques to find the solution.

For the equation [tex]\( -3x + 6 = 21 \)[/tex], the goal is to find the value of [tex]\( x \)[/tex] that makes the equation true. We start by isolating [tex]\( x \)[/tex] on one side of the equation. By subtracting 6 from both sides and then dividing by -3, we find [tex]\( x = -5 \)[/tex]. This is the solution to the equation.

On the other hand, for the inequality [tex]\( -3x + 6 < 21 \)[/tex], the goal is to find the values of [tex]\( x \)[/tex] that satisfy the inequality. We follow similar steps as with the equation but with one crucial difference: when dividing by a negative number, the direction of the inequality sign must be reversed. After isolating [tex]\( x \)[/tex], we find [tex]\( x > -5 \)[/tex]. This represents all values of [tex]\( x \)[/tex] that make the inequality true.

In summary, the process involves understanding whether we are dealing with equations or inequalities, isolating the variable, and solving for its value. For inequalities, attention must be paid to reversing the inequality sign when dividing by a negative number.
