Answer:

126 square inches of wrapping paper

Step-by-step explanation:

To compute for the minimum amount of wrapping paper Dylan will need to completely cover the box, you have to compute the surface area of the box. The formula in getting the surface area of a rectangle is:

A = 2WL + 2LH + 2HW

Substituting the given measurements to the formula:

A = 2(5)(6) + 2(6)(3) + 2(3)(5)

A = 60 + 36 + 30

A = 126 square inches

Therefore, Dylan needs to purchase at least 126 square inches of wrapping paper to completely cover the box.

Answer:

The total distance is  [tex]d_T = 6250 \ m[/tex]

Step-by-step explanation:

From the question we are told that

     The distance from bailey start point to her friends house is  [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]

       The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]

The total distance covered is mathematically evaluated as

         [tex]d_T = (2 * d_1) + d_2[/tex]

Substituting values

          [tex]d_T = (2 * 3000) + 250[/tex]

          [tex]d_T = 6250 \ m[/tex]

You can use the sine rule

a / sinA = b / sinB

Substitute the values in:

15 / sin112 = b / sin33

Multiply both sides by sin(33) to get b by itself

b = (15 / sin112) x sin33

Calculate this to get your answer of:

BC = 8.8 cm

2.

You can also use the sine rule here

sinA / a = sinB / b

Sub your values in:

sin84 / 32.4 = sin(y) / 21

Multiply both sides by 21 to isolate sin(y)

(sin84 / 32.4) x 21 = sin(y)

Calculate sin(y)

sin(y) = 0.6445975248

You now need to sin-1 this value to get u:

y = 40.13550596

To 1d.p, y = 40.1 degrees

Answer:

-The volume of a cylinder can be either:

In terms of pi: [tex]54\pi[/tex]

             or

Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]

Step-by-step explanation:

Use the formula for the volume of a cylinder and use the given radius and height for the formula:

[tex]V = \pi r^2 h[/tex]

[tex]V = \pi 3^26[/tex]

Then, solve the formula:

[tex]V = \pi \times 3^2 \times 6[/tex]

[tex]V = \pi \times 9 \times 6[/tex]

[tex]V = \pi \times 54[/tex]

[tex]V = 54\pi \approx 169.646[/tex]

-So, the answers would be:

56.52 km is the circumference of the circle.

The given figure is a circle with diameter 18km. The formula for calculating the circumference is expressed as:

C = 2πr

radius = diameter/2

radius = 18km/2

radius = 9km

Substitute to have:

C = 2(3.14)(9)

C = 56.52 km

Answer:

x = 65

Step-by-step explanation:

Complete question is:

Which is the correct solution?

x = 1.8

x = 2.6

x = 45

x = 65

SOLUTION:

The given equation is : [tex]\frac{x}{5}-2=11[/tex]

Substituting all the values of 'x' one by one

-> For  x = 1.8  : [tex]\frac{1.8}{5}-2=11[/tex]

-1.64≠11

-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]

-1.48≠11

-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]

7≠11

-> For x = 65 : [tex]\frac{65}{5}-2=11[/tex]

11=11

Therefore, by substituting x in every equation, x = 65

Answer:

Substitute 7 for a.

Simplify the equation after substituting the value for a.

Verify that a = 7 is correct when the result is a true statement.

Step-by-step explanation:

Here, the given equation is,,

And, after solving it the result is,

a = 7

We can check whether a result is the solution of an equation by substituting the result in the given equation.

If we get a true statement, then the result is the solution of the equation.

Thus, for verifying the solution, steps are as follow,

Step 1 : Substitute 7 ,

-9(7-5) = -18

Step 2 : Simplify the equation after substituting the value of a  

-9(2) = -18    

Step 3 : Verify that a = 7 is correct when the result is a true statement.

-18 = -18      

The equation to find the sum of interior angles of a n-sided polygon is:

(n - 2) * 180

So, we don't know what n is but we can make it look like this:

(n - 2) * 180 = 8,280

Solve for n.

(n - 2) * 180 = 8,280

~Divide 180 to both sides

(n - 2) * 180/180 = 8,280/180

~Simplify

n - 2 = 46

~Add 2 to both sides

n - 2 + 2 = 46 + 2

~Simplify

n = 48

Therefore, the polygon has 48 sides.

Best of Luck!

Step-by-step explanation:

-13x + 12 = 13x + 13

-13x - 13x = 13 - 12

-29x = 1

x = [tex] \frac{-29}{1} [/tex]

x = -1

12x + 12 = 13x + 12

12x - 13x = 12 - 12

-x = 0

-13x + 12 = 13x - 13

-13x - 13x = -13 - 12

-x = -25

x = 25

12x + 12 = 13x - 12

12x - 13x = -12 - 12

Answer:

x = -3

Step-by-step explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

4 ( 2x - 1 ) = 3x - 19

→ Expand the brackets

8x - 4 = 3x - 19

→ Minus 3x from both sides to isolate -19 and bring all the x coefficients to one side

5x - 4 = -19

→ Add -4 to both sides to isolate 5x

5x = -15

→ Divide both sides by 5 to isolate x and therefore find the value of x

x = -3

→ We can substitute x = -3 back into 4 ( 2x - 1 ) = 3x - 19 to see if we have the correct solution, if we end with the same number on both sides then  x = -3 is correct.

4 ( 2x - 1 ) = 3x - 19

8x - 4 = 3x - 19

( 8 × -3 ) - 4 = ( 3 × -3 ) - 19

-24 - 4 = - 9 - 19

-28 = -28

So x = -3 is correct

Answer:

see below

Step-by-step explanation:

A: radius of 12 ft

    Changing to meter

 12 ft * .305 m/ ft =3.66 meter

The radius is 3.66 meters

The diameter is twice the radius = 2*3.66 =7.32 meters

The circumference is

C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters

B diameter is 7.5 meters

Pool B has a bigger diameter

C = pi * d = 3.14 * 7.5m = 23.55 meters

The difference is .57 meters

Answer:

7.32

B

Larger/greater

0.57

Step-by-step explanation:

Diameter = 2 × radius

= 2 × 12 = 24 feet

24 × 0.305 = 7.32 meters

7.5 > 7.32

So the diameter of pool B is greater

Difference in circumferences:

(3.14 × 7.5) - (3.14 × 7.32)

23.55 - 22.98

0.57 meters
