You simply multiply 4.8 and 3.7 because if you notice the word "times," it explains you that you need to do multiplication.

4.8*3.7 = 17.76

So, Tripping ran 17.76 laps.

HOPE THIS HELPS!!!!

4.8*3.7 = 17.76

Question

What logarithmic equation has the same solution as x-4=2^3

Solution 1

What logarithmic equation has the same solution as x-4=2^3

Solution:

x-4=2³

x-4=2*2*2

x-4=8

TO solve for x, Let us add 4 on both sides

x-4+4=8+4

x+0=12

So, x=12

But, x=12 is not a logarithmic equation and there are no options

So, an equation like, x=㏒

As log has base 10,

So, x=㏒ =12

So, **logarithmic equation like x=log has same solution as x-4=2³**

Solution 2

**Answer:**

** is required lograthmic equation.**

**Step-by-step explanation:**

**Given: **Given equation, x - 4 = 2³

**To find: **Logarithmic function whose solution is same as given equation.

First we find the solution of given Equation.

consider,

x - 4 = 2³

x - 4 = 8 ( ∵ 2³ = 2×2×2 = 8 )

x = 8 + 4 ( Transposing 4 to RHS )

x = 12

Now we find the logarithmic equation whose solution is also x = 12.

( There exist many such equations )

Lets say one of them is,

Now we find its solution to check if it is same or not.

(using lograthmic rule,)

⇒ 2 × ( x + 2 ) = 28 (using lograthmic rule, )

⇒ 2x + 4 = 28

⇒ 2x = 28 - 4 (transposing 4 to RHS)

⇒ 2x = 24 (transposing 2 to RHS)

⇒

⇒ x = 12

Therefore, **is required lograthmic equation.**

Question

Two lines, C and D, are represented by the equations given below: Line C: y = x + 14 Line D: y = 3x + 2 Which of the following shows the solution to the system of equations and explains why?

Solution 1

The **solution** for the given system of **equations** are (6, 20).

A system of **linear equations** is a set of two or more equations involving two or more variables. All of the equations must be considered at once in order to find the solution, which is any pair of values that makes each equation true independently.

The given system of linear equations are y=x+14 -----(i) and y=3x+2 -----(ii).

From equation (i) and (ii), we get

x+14=3x+2

3x-x=14-2

2x=12

x=6

Substitute x=6 equation (i), we get

y=20

Therefore, the **solution** for the given system of **equations** are (6, 20).

Solution 2

**Answer:**

(6, 20), because both lines pass through this point

**Step-by-step explanation:**

We see that both equations are equal to y. This means we can set the two equations equal to each other:

x+14 = 3x+2

Subtract x from each side:

x+14-x = 3x+2-x

14 = 2x+2

Subtract 2 from each side:

14-2 = 2x+2-2

12 = 2x

Divide both sides by 2:

12/2 = 2x/2

6 = x

Substitute this into the first equation:

y = x+14

y = 6+14

y = 20

This makes the solution (6, 20).

Question

Solution 1

24 pints is the answer

Solution 2

24

One gallon holds eight pints. 8 x 3 = 24

One gallon holds eight pints. 8 x 3 = 24

Question

The diameter of a DVD is 12 centimeters. The hole in the center of a DVD has a diameter of 1.5 centimeters. Find the area of the DVD. Round to the nearest hundredth if necessary.

Solution 1

The area of the **circular DVD **is given by A = 111.33 cm²

A **circle **is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of **circle **= 2πr

The area of the circle = πr²

where r is the **radius **of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit **circle **, the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of **angle **θ is ( cos θ , sin θ )

Given data ,

Let the area of the **circular **DVD be A

Let the diameter of the DVD = 12 cm

So , the radius of the DVD = 6 cm

Now , the diameter of the hole = 1.5 cm

So , the radius of the hole = 0.75 cm

And , area of the **circular DVD **be A = π [ ( 6 )² - ( 0.75 )² ]

On simplifying , we get

The area of circular DVD is A = π ( 36 - 0.5625 )

The area of circular DVD is A = π ( 35.4375 )

The area of **circular DVD **is A = 111.33 cm²

Hence , the area of the **circular DVD **is 111.33 cm²

Question

Y=3x - 11
Y= -3x - 2

Solution 1

Subsitution method.

Y=3x - 11

Y= -3x - 2

-3x - 2 = 3x - 11

+3x +3x

-2 = 6x - 11

+11 +11

6x = 9

x = 1.5

Y=3(1.5) - 11

y = 4.5 - 11

y = -6.5

Now we have our points.

**Answer: x = 1.5 and y = -6.5**

Y=3x - 11

Y= -3x - 2

-3x - 2 = 3x - 11

+3x +3x

-2 = 6x - 11

+11 +11

6x = 9

x = 1.5

Y=3(1.5) - 11

y = 4.5 - 11

y = -6.5

Now we have our points.

Solution 2

Well, you do Equality method.

3x-11 = -3x-2

add 3x on both sides

6x-11 = -2

add 11 on both sides

6x = 9

divide 6 on both sides

x = 3/2

As you found the x value, you now need to find the y value by plugging in the x value in one of the above equations and solve for y.

y = 3x-11

y = 3(3/2) -11

y = 9/2 -11

y = -13/2

So, the answer is (3/2,-13/2) or (1.5,-6.5)

HOPE THIS HELPS!!!

3x-11 = -3x-2

add 3x on both sides

6x-11 = -2

add 11 on both sides

6x = 9

divide 6 on both sides

x = 3/2

As you found the x value, you now need to find the y value by plugging in the x value in one of the above equations and solve for y.

y = 3x-11

y = 3(3/2) -11

y = 9/2 -11

y = -13/2

So, the answer is (3/2,-13/2) or (1.5,-6.5)

Question

What must you do if you multiply one number in a ratio by n?

Solution 1

**Answer:**

multiply the others by n

**Step-by-step explanation:**

*If you want to keep the same ratio*, you must multiply all of the numbers by n.

A ratio of 1 : 1 will remain 1 : 1 if all the numbers are multiplied by n:

1 : 1 = n : n

_____

*Comment on alternate interpretation of the question*

There are occasions for multiplying the ratio by n:

x/n = 1/2

To solve this for x, we multiply the ratio (1/2) by n. This multiplies the numerator, but does not change the denominator.

x = n(1/2) = n/2
