Answer:

x =2/3

Step-by-step explanation:

4^3x=4^2​

Since the bases are the same, the exponents are the same

3x =2

Divide each side by 3

3x/3 = 2/3

x = 2/3

Step-by-step explanation:

Put your calculator this trigonometric function and you will get root of 3 over 2.

How ?

Answer:

.05

Step-by-step explanation:

if she made 19/20 shots, this means she missed 1/20

Decimals are on a scale of one hundred, therefore, we need to set the denominator to 100

To do this, multiply 1/20 times 5/5 and you should get 5/100

in decimal form, 5/100 is equal to this:

0.05

Answer:

1/2x-3=141

so first add 3 from both sides:

1/2x=141+3

1/2x=144

next divide is 1/2 on both sides

x=144/(1/2)

x=288

Answer:

x= 288

Step-by-step explanation:

1/2x-3=141

-3+3 which cancels out and you do 141+3 which gives you 145

you are left with 1/2x=145

and you divide 145 by 1/2x and you get

x=288

Step-by-step explanation:

$6+$1.10=$22.50

Add 1.10 to 6 ,15 times And you will get 22.50

Answer =15 miles

The question is asking how long was Sarah's taxi ride based on the taxi fare. This can be solved using algebra to set up an equation and solve for the total miles. The solution indicates that Sarah traveled a total of 18 miles.

This question involves a concept in algebra known as linear equations, which are used to express variable relationships. Similar to the Svetlana's tutoring fee problem, this taxi fare problem can be solved by writing an equation based on the given information.

The equation would look like this: $6.00 + $1.10(miles - 3) = $22.50 where miles represent the total miles traveled by Sarah. Subtract $6.00 from both sides: $1.10(miles - 3) = $16.50. Divide both sides by $1.10 you get: miles - 3 = 15. Now, if we add 3 to both sides of the equation, we get: miles = 15 + 3 = 18.

So, Sarah traveled a total of 18 miles for her taxi ride.

Answer:

(1,1)         (2,5)         (3,9)

Step-by-step explanation:

The surface area of the cylinder, with a radius of 39 inches and a height of 33 inches, is calculated using the formula for the surface area of a cylinder. It amounts to a total of 7386pi square inches, separating the calculation into the lateral surface area and the area of the bases for clarity.

The question is about finding the surface area of a cylinder where the radius of the base is 39 inches and its height is 33 inches, all in terms of pi. To find the surface area of a cylinder, we use the formula: 2(pi)(r)(height) + 2(pi)(r)^2. Substituting the given values, we have 2(pi)(39)(33) for the surface area of the sides, and 2(pi)(39)^2 for the two circular ends.

Therefore, the total surface area in terms of pi is: 2(pi)(39)(33) + 2(pi)(39)^2. This simplifies to: 2562pi + 4824pi, resulting in a total surface area of 7386pi square inches.

This approach easily demonstrates the process of calculating the surface area of a cylinder by focusing on its geometrical components: the lateral surface area and the area of the two circular bases.

Answer:

81 square feet

Step-by-step explanation:

Given the function

A(W) = 18w – [tex]w^{2}[/tex]

To find the greatest possible area the farmer can enclose in a rectangular pen

with 36 feet of fencing, we take the derivative on both sides of the function:

A'(w) = 18 -2w

=> A''(w) = -2

Since A"(w) is in negative, so the critical value will yield maximum value of the function.

So, A'(w) = 0

<=> 18 -2w = 0

<=> w = 9

Substitute w= 9  into the A(W) = 18w – [tex]w^{2}[/tex] , we have the greatest possible area is:

= 18*9 - [tex]9^{2}[/tex]

= 81 square feet

Option C, x - 2y = -16

Step-by-step explanation:

Step 1:  Find the slope

[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]

[tex]m = (11 - 10) / (6 - 4)[/tex]

[tex]m = 1 / 2[/tex]

Step 2:  Plug in into point-slope form

[tex](y - y_1) = m(x - x_1)[/tex]

[tex](y - 10) = 1/2(x - 4)[/tex]

[tex]y - 10 = 1/2x - 2[/tex]

Step 3:  Solve for x

[tex]y - 10 + 2 = 1/2x - 2 + 2[/tex]

[tex](y - 8) * 2/1 = 1/2x * 2/1[/tex]

[tex]2y - 16 = x[/tex]

Step 3:  Put the variables on one side

[tex]2y - 16 - 2y = x - 2y[/tex]

[tex]-16 = x - 2y[/tex]

[tex]x - 2y = -16[/tex]

Answer: Option C, x - 2y = -16

Answer:

$577.27

Step-by-step explanation:

When offered 15% discount, buyer will then pay 100-15=85% of the original price hence the price offered by seller will be

0.85*$630=$535.5

Now this price is subjected to a tax of 7.8%, equivalent to 0.078 hence the buyer pays 1.078 of $535.5

1.078*$535.5=$577.269

Rounded off, this is equivalent to $577.27

Answer:

Time per cardio class: 32 minutes

Time per weightlifting class: 40 minutes

Step-by-step explanation:

Start by creating a system of equations:

let c = the time per cardio class

let w = the time per weightlifting class

4c + 5w = 328

4c + w = 168

Solving for c and w get you 32 minutes and 40 minutes respectively

Each cardio class lasts 32 minutes and each weightlifting class lasts 40 minutes.

To find out how long each class is, we need to set up a system of equations based on the information given.

Let's denote the duration of a cardio class by C minutes and the duration of a weightlifting class by W minutes.

1. From the first week, we have the equation:

4C + 5W = 328

2. From the second week, we have:

4C + 1W = 168

3. To eliminate C, we can subtract the second equation from the first:

(4C + 5W) - (4C + 1W) = 328 - 168

4W = 160

W = 40

4. Now substitute W back into the second equation:

4C + 40 = 168

4C = 128

C = 32

Therefore, each cardio class lasts 32 minutes and each weightlifting class lasts 40 minutes.
