5×+23= 53

5×+23-23= 53-23

5x=30

30÷5=6

Answer:

The answer is B.

Step-by-step explanation:

The easiest way to solve these is by taking the total number/ 53 and subtracting it by the number you do know/ 23. In this case you would get 30. Then you multiply 5 to get 30. Which is 6.

To convert -25.49 decimal degrees to degrees, minutes, and seconds, the answer is -25° 29' 24". This conversion involves separating the degree, multiplying the decimal part by 60 for minutes, and doing the process again for seconds.

To change the decimal degree -25.49 to degrees, minutes, and seconds (DMS):

The negative sign indicates the direction (west or south, depending on the context).

The answer is -25° 29' 24" (which might be west or south, depending on context).

Answer:

See below for answers

Step-by-step explanation:

Part 1:

Angle 1 is a supplementary angle, so it must be 180-50=130 degrees because supplementary angles add up to 180 degrees.

Angle 2 is a vertical angle, therefore it must be 50 degrees as well because vertical angles are congruent.

Angle 3 is vertical to angle 1, so it is 130 degrees since vertical angles are congruent.

Part 2:

x and 2x+21 are supplementary angles, so we can make an equation:

x+2x+21=180

3x+21=180

3x=159

x=53

So x=53

Answer:

1 = 130

2 = 50

3 = 130

4 = x = 53

Step-by-step explanation:

angle 2 is congruent to 50 degrees

1 and 3 are congruent

1 and 2 are supplementary

3x+21 = 180

3x = 159

x = 53

The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

          Cylinder has a 5 centimeters height

          Diameter of the cylinder is 1.5 centimeters

Step:1

          Formula for the surface area of cylinder is,

                     [tex]A=2\pi r h + 2\pi r^{2}[/tex]......................................(1)

          Where,

                   h - Height of cylinder

                   r - Radius of cylinder

        From the values of h and r,

                   [tex]r=\frac{d}{2}[/tex]

                      = [tex]\frac{1.5}{2}[/tex]

                   r  = 0.75 cm

       From the formula,

                      = ( 2 × [tex]\pi[/tex] × 0.75 × 5 ) + ( 2 × [tex]\pi[/tex] × [tex]0.75^{2}[/tex] )

                      = ( 7.5 [tex]\pi[/tex] ) + ( 1.125 [tex]\pi[/tex] )

                  A = 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex]

Result:

        The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.

The surface area of a cylinder is 8.625π cm². Thus, the correct answer is B.

First, calculate the radius of the cylinder, which is half of the diameter:

r = 1.5 cm / 2

   = 0.75 cm

Next, find the area of the two circular bases of the cylinder using the formula for the area of a circle, A = πr²:

Area of one base = π(0.75 cm)²

                              = 0.5625π cm²

Total area of the two bases = 2 × 0.5625π cm²

                                              = 1.125π cm²

Then, calculate the lateral surface area using the formula for the circumference of a circle (C = 2πr) multiplied by the height (h):

Lateral surface area = 2π(0.75 cm)(5 cm)

                                  = 7.5π cm²

Finally, add the areas of the two bases and the lateral surface area to find the total surface area:

Total surface area = 1.125π cm² + 7.5π cm²

                              = 8.625π cm²

The correct answer is B. 8.625π cm².

The solution to the system of equations is x = 4 and y = 2.

Let's solve the system of equations:

4x - 12y = -8

-3x + 12y = 12

We can solve this system using the method of addition or elimination. Adding the two equations eliminates y:

(4x - 12y) + (-3x + 12y) = -8 + 12

Simplifying:

4x - 3x = 4

x = 4

Now that we have found x = 4, we can substitute this value back into one of the original equations to solve for y. Let's use the second equation:

-3x + 12y = 12

-3(4) + 12y = 12

-12 + 12y = 12

12y = 12 + 12

12y = 24

y = 24 / 12

y = 2

B

Answer:

Step-by-step explanation:

There are two ways to find the value of m∠ ABT

By using trigonometric ratio:

1 - Draw a perpendicular AT

2 - Now the Δ ABT is a right-angle triangle. therefore by using trigonometric ratio

Sine X = Perpendicular / Hypotenuse

Sine X = AT/AB

X = Sine-1 AT/AB.

others ratio can also be used i.e cos x & tan x.

Answer:

Step-by-step explanation:

The measure of the radius of the circle C will be 12 units.

Let r be the radius of the sector and θ be the angle subtends by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The central angle is 5π / 6 radian. And the arc length is 10π. Then the measure of the radius of the circle is given as,

10π = ((5π / 6)/2π) 2π r

Simplify the equation, then we have

5 = (5 / 12) r

r = 12 units

The measure of the radius of the circle C will be 12 units.

More about the arc length of the sector link is given below.

Answer:

5 and 7.

Step-by-step explanation:

Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:

*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.

[tex]x *(x+2)=35[/tex]

Expanding, you get:

[tex]x^{2}+2x = 35.[/tex]

And moving the 35 to the other side, you get a simple quadratic.

[tex]x^{2}+2x -35 =0.[/tex]

Solving by factoring:

[tex](x+7)(x-5)[/tex]

This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).
