The sum of two numbers is 24. Twice the first number plus the second is 26. Find the numbers. ​

Answers

Answer:

2 and 22

Step-by-step explanation:

You can put them into equations:

x+y=24 and 2x+y=26

Then, for each equation solve for one of the variables. It doesn't really matter which one but I chose y here.

y=24-x and y=26-2x

Since both equations are equal to y it means that the expression on the right sides of the equal sign are equal to each other:

24-x=26-2x

From here solve for x and you are left with:

x=2

Now that you know one variable go back and plug it into an equation and solve for y. Again, it doesn't matter which one you choose, you will end up with the same answer:

(2)+y=24

So..

y=22

Warm up: solve for the variable

Given: x - 8 > -3. solution set

Answers

Answer:   x > 5

Reason:

Add 8 to both sides to undo the -8

We have x-8 > -3 become x > -3+8 which becomes x > 5

We can replace x with anything larger than 5.

A garden has the shape of a circular sector such that its straight sides measure 50 feet in length and the central angle is 132°. if the garden needs to be surrounded by fencing, how many feet are needed to enclose the garden?

Answers

Answer:

  215 ft

Step-by-step explanation:

The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...

  s = r·θ . . . . . where θ is the central angle in radians

__

arc length

There are π radians in 180°, so the arc will have a measure in radians of ...

  θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians

Then the length of the curved side of the garden is ...

  s = (50 ft)(2.3038 radian) ≈ 115.2 ft

__

perimeter

The fence length is the sum of the arc length and the two radii:

  perimeter = 115.2 ft + 2×50 ft = 215.2 ft

About 215 feet of fencing are needed to enclose the garden.

The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.

What is moment of inertia?

Moment of inertia is the quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.

Using the formulas to calculate the moment of inertia of a solid cylinder:

I = ½MR²

Where;

I = moment (kgm²)

M = mass of object (Kg)

R = radius of object (m)

Total moment of inertia of the two disks is expressed as: I = I(1) + I(2)

That is;

I = ½M1R1 + ½M2R2

According to the provided information;

R1 = 2.50cm = 0.025m

M1 = 0.800kg

R2 = 5.00cm = 0.05m

M2 = 1.70kg

I = (½ × 0.800 × 0.025²) + (½ × 0.05² × 1.70)

I = (½ × 0.0005) + (½ × 0.00425)

I = (0.00025) + (0.002125)

I = 0.002375

I = 2.375 × 10-³ Kgm²

Hence The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.

For the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

What is a cube?

It is defined as three-dimensional geometry that has six square faces and eight vertices.

We have

1) Side length = 3.2 dm

Volume = (3.2)³ = 32.768 dm³

2) Volume of cube = 216 cubic meters

a³ = 216

a = 6 meters

3) The dimensions for sewing box: 10 cm, 8 cm, and 6 cm

Volume = 10×8×6 = 480 cubic cm

Similarly, we can calculate the rest of the data.

Thus, for the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

Write a sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​

Answers

A sine wave is also known as a sinusoid. The sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.

What is sine function?

A sine wave, also known as a sinusoid, is the graph of the sine function. Any curve that can be expressed in the form is referred to as a sinusoid. (A and B are both positive.) Sinusoids are the most generic version of the sine function.

Given the amplitude of the function is 5, the vertical shift is 3, and the period of 3/7. Therefore, the values of constants can be written as,

a = 5

b = (2π)/(3/7) = 14π/3

d = 2

Substituting the values in the sine function,

a sin b (x-c) + d

= 5 Sin(16π/3)(x-0) + 2

= 5 Sin(16πx/3) + 2

Hence, the sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.
