Answer:

2/3* 4/5 = 8/15

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached file below.

Given:

So assume that the the playground is divided into 5 equal part

=> 1 part is used for students to sit and read or (1/5)

=>  the remaining equal part is 4  or (4/5)

Because 2/3 of the remaining part is used for playing soccer

=> the equation represents the part of the playground used for soccer is:

2/3 of 4/5

= 2/3* 4/5

= 8/15

To find the part of the playground used for soccer, remember one-fifth is for reading, leaving four-fifths. Then, calculate three-quarters of the remaining area for soccer.

To represent the part of the playground used for soccer, we need to consider that one-fifth of the playground is used for students to sit and read. Therefore, the remaining four-fifths of the playground is available for other activities. Since three-quarters of the remaining playground is used for playing soccer, the equation representing the part of the playground used for soccer is:

4/5 * 3/4 = 12/20 = 3/5

Our answer is [tex]x=9[/tex]

Step-by-step explanation:

First we will rearrange so we have to divide by 7.

[tex]\frac{x}{3}= \frac{2x+3}{7}[/tex]

Now we will cross multiply.

So...

[tex]x*7 \\3*2x+3[/tex]

Our new equation will look like:

[tex]7x=6x+9[/tex]

Now we have to isolate x.

So we have to subtract 6x from both sides.

[tex]7x-6=1x[/tex]

and

[tex]6x-6x=0[/tex]

Our new equation is:

[tex]1x=9[/tex]

Now divide.

Our answer is [tex]x=9[/tex]

Answer:

f(6)=-29

Step-by-step explanation:

f(6)=-5(6)+1

f(6)=-30+1

f(6)=-29

The value of f(6) is -29.

Given,

f(x)= -5x+1

We need to find f(6).

A function is denoted by f(x) and the point can be a value of x.

The x values are called domain and f(x) is called the output.

Example:

f(x) = x + 2

At x = 1

f(1) = 1 + 2 = 3.

Find f(x) = -5x + 1 at x = 6.

f(x) = -5x + 1

f(6) = - 5 x 6 + 1

     = -30 + 1

     = -29

This means the function f(x) is -29 at x = 6.

Thus the value of f(6) is -29.

Answer:

16400 in ^2

Step-by-step explanation:

For area, we multiply by the scale factor squared

area 2 = sf^2 * area 1

Since the scale factor is 10,

area 2 = 10^2* 164

           = 100*164

           = 16400

Answer:

16,400 in²

Step-by-step explanation:

Ratio of Areas = (Ratio of sides)²

A/164 = 10²

A/164 = 100

A = 16400

Answer:

(2,5)

Step-by-step explanation:

If you are flipping a point over the x-axis, multiply the y coordinate by -1, if you are flipping something over the y-axis, multiply the x coordinate by -1.

The coordinates of point B are (2,5)

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

Given that  coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B.

Since flipping a point over the x-axis, then we have to multiply the y coordinate by -1,

And ifyou are flipping something over the y-axis, then we have to multiply the x coordinate by -1.

Therefore, the point B are (2, _5_).

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)

Step-by-step explanation:  

Total number of cars = 150

Cars that failed the safety inspection = 18

The proportion is given by

p = 18/150

p = 0.12

p = 12%

The confidence interval is given by

p ± margin of error

Where margin of error is 0.02

0.12 ± 0.02

Lower limit = 0.12 - 0.02

Lower limit = 0.10

Lower limit = 10%

Upper limit = 0.12 + 0.02

Upper limit = 0.14

Upper limit = 14%

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)

21x-15

Step-by-step explanation:

Use the distributive property:

3×7x=21x

3×5=15

Don't forget the - sign!!!

So,

3(7x - 5) = 21x - 15

Final answer:

The expression 3(7x - 5) using the distributive property is equivalent to 21x - 15, which is obtained by multiplying 3 by each term inside the parenthesis.

Explanation:

The expression 3(7x
- 5) is equivalent to 21x - 15. This process is known as the distributive property, where you multiply the number outside the parenthesis by each term inside the parenthesis. Let's break it down step by step:

Multiply the first term inside the parenthesis by 3: 3 ×7x = 21x.

Multiply the second term inside the parenthesis by 3: 3 ×(-5) = -15.

Combine these results to get the equivalent expression: 21x - 15.

The number of solutions for the given equation is one.

Here, we have,

To determine the number of solutions for the equation 3(x - 2) = 22 - x, we can solve it and analyze the result.

Let's simplify and solve the equation step by step:

3(x - 2) = 22 - x

3x - 6 = 22 - x

4x = 28

x = 7

After simplifying, we find that x = 7.

Now, we can analyze the number of solutions:

Since we have found a specific value for x that satisfies the equation, namely x = 7, there is exactly one solution.

Therefore, the number of solutions for the given equation is one.

Answer:

18.02 cm

Step-by-step explanation:

A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.

Remember, because we know the length and width, we know the two sides.

10^2 + 15^2 = c^2

100+225 = c^2

325 = c^2

18.027 ≈ c

We can use the Pythagorean theorem to solve for the diagonal. The diagonal is the same as the hypotenuse of a triangle.

Pythagorean Theorem: a² + b² = c²

Now, solve for the diagonal.

(10)² + (15)² = c²

100 + 225 = c²

325 = c²

√325 = √c²

18.0277... = c

Round if necessary.

18.0277... = 18.03

Therefore, the diagonal of the rectangle is approximately 18.03cm.

#We use the circumference formula to calculate the radius:

[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]

-The volume of the cone using the radius above can then be calculated as follows:

Answer:

34.3 meters

Step-by-step explanation:

The generic equation for a movement with constant acceleration is:

S = So + Vo*t + (a*t^2)/2

Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.

If we compare with our equation (where x is the time and f(x) is the final distance), we have that:

So = 34.3

Vo = 29.4

a = -9.8

So we have that the inicial position (So) of the object is 34.3 meters
