Step-by-step explanation:

2(2x+1)=x+5

4x+2=x+5

3x=3

x=1

Answer:

x=1

Step-by-step explanation:

2(2x + 1) = x + 5

Distribute

4x +2 = x+5

subtract 4 from each side

4x-x +2 = x-x+5

3x +2 = 5

Subtract 2 from each side

3x+2-2 = 5-2

3x = 3

Divide by 3

3x/3 = 3/3

x=1

To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.

a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.

b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.

The volume of pearl is 39 cubic millimeters, if A necklace has a single pearl with a radius of 2.1 millimeters.

Step-by-step explanation:

The given is,

                   Pearl with a radius of 2.1 millimeters

Step:1

                   Pearl shape general looks like a sphere,

                   Volume of sphere,

                                                 [tex]V= \frac{4}{3}r^{3}[/tex]...............................(1)

                  Where, r - Radius of sphere

                  From the given values,

                                         r - 2.1 millimeters

                  Equation (1) becomes,

                                                    [tex]= \frac{4}{3}\pi (2.1)^{3}[/tex]

                   Substitute the value of [tex]\pi[/tex],

                                                    [tex]= (1.33333333)(\frac{22}{7} ) (9.261)[/tex]          ( ∵ [tex]\pi = \frac{22}{7}[/tex] )

                                                    [tex]=(4.190476)(9.261)[/tex]  

                                                    = 38.79

                                                    ≅ 39 cubic millimeters

                   Volume of pear, V = 39 cubic millimeters    

Result:

             The volume of pearl is 39 cubic millimeters, if A necklace has a single pearl with a radius of 2.1 millimeters.

Given:

Image of the figure

To find:

The area of the figure.

Solution:

The image is splitted into two shapes.

One is rectangle and the other is trapezium.

Reference image for answer is attached below.

Rectangle:

Length = 10 cm

Width = 2.8 cm

Area = length × width

        = 10 × 2.8

Area = 28 cm²

Trapezium:

Top base = 6 cm

Bottom base = 10 cm

Height = 7.2 - 2.8 = 4.4 cm

Area = [tex]\frac{1}{2} \times\left(b_{1}+b_{2}\right) \times h[/tex]

        [tex]$=\frac{1}{2} \times(6+10) \times 4.4[/tex]

        [tex]$=\frac{1}{2} \times 16 \times 4.4[/tex]

Area = 35.2 cm²

Area of the figure = 28 cm² + 35.2 cm²

                             = 63.2 cm²

The area of the figure is 63.2 cm².

Answer:

The missing data value is 147

Step-by-step explanation:

The mean is 120

The standard deviation is 9

Missing data value = ?

From the question, the missing data value is 3 standard deviation away from the mean.

3 standard deviation = 3 * 9 = 27

3 standard deviation from the mean = 120 + 27 = 147

The missing data value is what we get after adding 3 standard deviation from the mean.

Away here means ahead which is sum.

Answer:

0°

360°

Step-by-step explanation:

We want to solve the equation,

[tex] \cos(x + 45) + \cos(x - 45) = \sqrt{2} [/tex]

We expand using trigonometric identities to get;

[tex]\cos(x) \cos( 45) - \sin(x) \sin(45) + \cos(x) \cos( 45) + \sin(x) \sin(45) = \sqrt{2} [/tex]

[tex] \frac{ \sqrt{2} }{2} \cos(x) - \frac{ \sqrt{2} }{2} \sin(x) + \frac{ \sqrt{2} }{2} \cos(x) + \frac{ \sqrt{2} }{2} \sin(x) = \sqrt{2} [/tex]

Simplify;

[tex] \cos(x) - \sin(x) + \cos(x) + \sin(x) = 2[/tex]

Simplify;

[tex]\cos(x) + \cos(x) = 2[/tex]

Add

[tex]2\cos(x) = 2[/tex]

Divide by 2

[tex]\cos(x) = 1[/tex]

Take cosine inverse;

In the

[tex]x = \cos^{ - 1} ( 1) =0\degree [/tex]

Also in the 3rd quadrant cosine ratio is positive.

[tex]x = 360-0= 360 \degree[/tex]

Answer:

2162 miles

Step-by-step explanation:

The equation of the circumference of a circle is d*pi = Circumference. Knowing this, We can do a one step equation and divide be pi on both sides to find the diameter. All you have to do is plug the numbers in and divide 6790 by 3.14 to find 2162. (Rounded to the nearest mile)

Final answer:

To find the diameter of the moon, use the formula for circumference. Given the circumference of the moon, substitute the value into the formula to find the radius. Multiply the radius by 2 to find the diameter. Round the result to the nearest mile.

Explanation:

To find the diameter of the moon, we can use the formula for circumference: Circumference = 2πr, where r is the radius. Given that the circumference of the moon is about 6,790 miles, we can rearrange the formula to solve for the diameter. Since diameter is twice the radius, we have Diameter = 2r. Substitute the given circumference value into the formula to find the radius. Then multiply the radius by 2 to find the diameter. Round the result to the nearest mile.

Step 1: Circumference = 2πr

Step 2: Given circumference = 6,790 miles

Step 3: Solve for r: 6,790 miles = 2πr

Step 4: Divide both sides of the equation by 2π: r ≈ 1,080 miles

Step 5: Multiply r by 2 to find the diameter: Diameter ≈ 2 * 1,080 miles ≈ 2,160 miles

Therefore, the diameter of the moon, rounded to the nearest mile, is approximately 2,160 miles.

Answer:

2.1375 bottles of paint

Step-by-step explanation:

cardboard length = 14 1/4 ft, which is equivalent to (4*14 + 1)/4 = 57/4 ft

cardboard width = 6 ft

Rectangular cardboard area = length * width = 57/4 * 6 = (57*6)/4 = 342/4 ft²,  which can be simplified dividing numerator and denominator by 2: 171/2 ft²

If 1 bottle of paint covers an area of 40 square feet, then to paint 171/2 square feet the following proportion must be satisfied:

1  bottle of paint / 40 square feet = x bottles of paint / (171/2) square feet

x = (1/40) * (171/2) = (1*171)/(40*2) = 171/80 or (160 + 11)/80 = 160/80 + 11/80 = 2 11/80 or 2.1375 bottles of paint

Answer:

[tex](D)x^{3/4}y^{1/2}[/tex]

Step-by-step explanation:

We are required to simplify the expression: [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})[/tex]

This is a product and the first thing we will do is to collect like terms:

[tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{1/2}x^{1/4}y^{1/3}y^{1/6}[/tex]

Next, we apply the addition law of indices: [tex]x^a X x^b =x^{a+b}[/tex]

[tex]x^{1/2}x^{1/4}y^{1/3}y^{1/6}=x^{1/2+1/4}y^{1/3+1/6}\\\\=x^{3/4}y^{1/2}[/tex]

Therefore, [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{3/4}y^{1/2}[/tex]

Step-by-step explanation:

Two secants from an external point to a circle, then the product of one secant's external part and the entire secant is equal to the product of the external part and the entire secant of the other, that is

(x - 2)(x - 2 + x + 4) = 4(4 + 5)

(x - 2)(2x + 2) = 4(9) = 36 ← distribute and simplify the left side

2x² + 2x - 4x - 4 = 36

2x² - 2x - 4 = 36 ( subtract 36 from both sides )

2x² - 2x - 40 = 0 ( divide through by 2 )

x² - x - 20 = 0 ← in standard form

(x - 5)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 4 = 0 ⇒ x = - 4

But x > 0 ⇒ x = 5

Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct  strategy for stacking the blocks

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The block has the following dimensions:

( L x w x h ) = ( 8 x 5 x 6 ) in

We will determine the surface area of each unique face of the block given in the attachment.

Surface area of the face ( 8 x 5 ):

Area = ( 8 )×( 5 )

Area = 40 in²

Surface area of the face ( 8 x 6 ):

Area = ( 8 )×( 6 )

Area = 48 in²

Surface area of the face ( 6 x 5 ):

Area = ( 5 )×( 6 )

Area = 30 in²

Hence, Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct  strategy for stacking the blocks
