Solve 3x - x + 2 = 12. (1 point) Оа 7 5​

Step-by-step explanation:

The statement is true, because when we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.

A relation by which we can compare two or more mathematical expression is called an inequality.

Let an example of the inequality as;

⇒ 2x < 3

Multiply by - 1, we get;

⇒ - 2x > - 3

Thus, When we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.

D

Step-by-step explanation:

The domain of a parabola is always x er, unless it's been inverted then it's the opposite.

To calculate the duration of the shift, you need to subtract the clock-in time from the clock-out time.

In this case, the shift worker clocked in at 1730 hours (5:30 PM) and clocked out at 0330 hours (3:30 AM). However, since the clock is based on a 24-hour format, it's necessary to consider that the clock-out time of 0330 hours actually refers to the next day.

To calculate the duration of the shift, you can perform the following steps:

1. Calculate the duration until midnight (0000 hours) on the same day:

  - The time between 1730 hours and 0000 hours is 6 hours and 30 minutes (1730 - 0000 = 6:30 PM to 12:00 AM).

2. Calculate the duration from midnight (0000 hours) to the clock-out time:

  - The time between 0000 hours and 0330 hours is 3 hours and 30 minutes (12:00 AM to 3:30 AM).

3. Add the durations from step 1 and step 2 to find the total duration of the shift:

  - 6 hours and 30 minutes + 3 hours and 30 minutes = 10 hours.

Therefore, the duration of the shift was 10 hours.

Answer:

8 bags of chips.

Step-by-step explanation:

First, find the cost per individual unit. It is given that 2 bags of chips cost $6. Find the cost of one bag by dividing 6 with 2:

$6/2 bags = $3/bag

Next, you are solving for the amount of chips you can buy with $24. Divide 24 with the individual cost of $3:

$24/$3 per bag = 8

You can buy 8 bags of chips assuming all things are the same.

To find the mass and center of mass of the solid bounded by the paraboloid z = 8x^2 + 8y^2 and the plane z = a, we can use cylindrical coordinates.

In cylindrical coordinates, the paraboloid can be expressed as z = 8r^2, where r is the radial distance and z is the height.

To find the mass of the solid, we need to integrate the density function over the volume of the solid. Since the solid has constant density k, the mass can be expressed as:

M = ∭ k dv

Using cylindrical coordinates, the volume element (dv) is given by dv = r dz dr dθ.

The bounds for the integral are as follows:

r: from 0 to √(a/8) (due to the paraboloid equation z = 8r^2)

θ: from 0 to 2π (to cover the entire azimuthal angle)

z: from 0 to a (due to the plane z = a)

Now, let's evaluate the integral for the mass:

M = ∭ k dv = ∫[z=0 to a] ∫[θ=0 to 2π] ∫[r=0 to √(a/8)] k r dz dr dθ

The integration process will yield the mass M of the solid.

To find the center of mass, we need to evaluate the triple integral:

(x_cm, y_cm, z_cm) = (1/M) ∭ (x, y, z) k dv

Where (x_cm, y_cm, z_cm) represent the coordinates of the center of mass.

The integrals for each coordinate can be set up similarly to the mass integral, using the appropriate expressions for x, y, and z in terms of cylindrical coordinates. Then, divide each integral by the mass M to obtain the coordinates of the center of mass.

Note that the calculations can be quite involved, so it's recommended to use software or a computer algebra system to perform the integrations and simplify the expressions.

Answer: If 50% of the 8 espressos sold were single-shot, that means the other 50% must have been double-shot.

To find out how many single-shot espressos were sold, we can calculate 50% of 8, which is:

0.5 x 8 = 4

So the cafe sold 4 single-shot espressos.

To find out how many double-shot espressos were sold, we can calculate the other 50% of 8, which is also 4.

Therefore, the cafe sold 4 single-shot espressos and 4 double-shot espressos in total.

Answer:

It is given that in every 1/2 hours  Brandon bikes .

The distance 8 1/2 miles  is in the form of mixed fraction.

Therefore, the distance 8 1/2 miles can be written in the form of decimal as follows:

8 1/2 miles = 8.5 miles

Brandon bike's 8.5 miles  in every 1/2 hours .

We know that 1 hour   is equivalent to 60 minutes .

So,  0.5 hours can be converted into minutes as follows:

1 hour = 60 minutes

1.5 hours= 30 minutes

Therefore, in every 30 minutes Brandon bikes .

So, in next 30 minutes Brandon also bikes 8.5 miles .

In every 1 hour   Brandon travels  = 8.5+8.5 = 17 miles.

In every 1:30  Brandon travels  17 +8.5 =25.5 miles.

Method 2:

Speed of Brandon’s bike can be calculated as ,

speed = distance/time

Here, d  is the distance and t is the time.

Now, substitute d=8.5  and t= 0.5 in the equation (1)

Therefore, the rate of travelling of Brandon’s bike is .

If the scale factor is 3/4. Then the perimeter of the original triangle will be 66.67 units.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

A triangle with a perimeter of 50 units is the image of a triangle that was dilated by a scale factor of 3/4.

Then the perimeter of the preimage, the original triangle, before its

dilation will be

Let c be the perimeter of the original triangle.

Then we have

So, the simplified expression that represents the total cost is 8(x + 0.34375) dollars.

Let x be the cost of one scoop of ice cream without any toppings. Then the total cost for each kid who adds sprinkles is x + 0.25, the total cost for each kid who adds nuts is x + 0.35, and the total cost for each kid who adds nothing extra is x.

Therefore, the total cost for the 10 kids is:

5(x + 0.25) + 3(x + 0.35) + 2x = 8x + 2.75

Simplifying this expression, we get:

8x + 2.75 = 8(x + 0.34375)
