Solve for x (Will get brainliest award)​

Given:

Area of a sector = [tex]15\pi[/tex]

Radius = 5 cm

To find:

The central angle.

Solution:

The area of a sector is:

[tex]A=\dfrac{1}{2}r^2\theta[/tex]

Where, r is the radius and [tex]\theta[/tex] is the central angle in radians.

Putting [tex]A=15\pi, r=5[/tex] in the above formula, we get

[tex]15\pi=\dfrac{1}{2}(5)^2\theta[/tex]

Multiply both sides by 2.

[tex]30\pi=25\theta[/tex]

Divide both sides by 25.

[tex]\dfrac{30\pi}{25}=\theta[/tex]

[tex]\dfrac{6\pi}{5}=\theta[/tex]

Therefore, the central angle in radians is [tex]\theta=\dfrac{6\pi}{5}[/tex].

Answer:

20

Step-by-step explanation:

5*4=20

5*5=25, but it is bigger than 24.

So the ans is 20

Answer:

6)  x = 40.5

8)  x = 16.5

Step-by-step explanation:

6) 45/x = 20/18

simplify and cross-multiply to get:

45/x = 10/9

10x = 405

x = 40.5

8) 22/8 = x/6

11/4 = x/6

4x = 66

x = 33/2

x = 16.5

Answer:

The minimum number of hours the plumer can work is 1 hour and 15 minutes and the maximum number of hours is 6.

Step-by-step explanation:

The new dimension of the rectangle is 14.4 cm ×5.4 cm option (A) is correct if the rectangle is dilated by a scale factor of 3.6.

The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a rectangle shown in the picture.

The width of the rectangle  = 1 1/2 = 3/2 = 1.5 cm

The length of the rectangle = 4 cm

The rectangle is dilated by a scale factor of 3.6:

The new width of the rectangle = 1.5×3.6 = 5.4 cm

The new length of the rectangle = 4×3.6 = 14.4 cm

The dimension of the new rectangle = 14.4 cm ×5.4 cm

Thus, the new dimension of the rectangle is 14.4 cm ×5.4 cm option (A) is correct if the rectangle is dilated by a scale factor of 3.6.

Answer:

D. an = 4n

Step-by-step explanation:

The formula for finding a term of an arithmetic sequence is:

an = a1 + (n-1)d

where an is the nth term, a1 is the first term and d is the common difference between the terms.

To find d we can take any two adjacent terms and subtract one from the other. e.g. 8 - 4 = 4, 16-12 = 4 etc.

The common difference here is 4, and we can see that the first term of the sequence is also 4, therefore our formula now looks like this:

an = 4 + (n-1)4

Now we can just expand out the brackets to find the final answer:

an = 4 + 4n - 4

an = 4n

2. The square root of an imperfect square

Step-by-step explanation:

A rational number is any number that can be written as a fraction (with the numerator and denominator being integers). All terminating and repeating decimals are rational.

The square root of an imperfect square is always irrational.

Note: Consider the solid object is a cylinder because the radius of base and height of the solid is given.

Given:

Radius of base = 7 cm

Height = 12 cm

To find:

The volume of the given solid.

Solution:

The volume of a cylinder is:

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

Where, r is the radius of the base and h is the height of the cylinder.

Putting [tex]r=7,h=12,\pi=\dfrac{22}{7}[/tex] in the above formula, we get

[tex]V=\dfrac{22}{7}\times(7)^2\times (12)[/tex]

[tex]V=22\times 7\times 12[/tex]

[tex]V=1848[/tex]

Therefore, the volume of the given solid is 1848 sq. cm.

Answer:

A  =  $94652.66

Step-by-step explanation:

Use the compound amount formula   A = P(1 + r/n)^(nt), where r is the annual interest rate and n is the number of compounding periods per year.

Here, A = ($77000)(1 + 0.07/2)^(2*3), or

          A = $77000(1.035)^6, or

          A  =  $77000(1.229), or

           A  =  $94652.66

Answer:

The top looks like a trapezoid and so does the bottom so it's a prism.

lets find the area of the base!

15(base 1) + 7(base2) = 22

22 x 5(height) = 110

110 divided by 2( x 1/2) = 55

Now we multiply by the actual height of the TOTAL prism which is 11.

55 x 11 = 605 cubic feet, is your answer.

Formula for AREA of a trapezoid:

B1(base 1) + B2(base 2) x H(height) x 1/2 (basically just dividing by 2)
