Answer:

706.50 mm^2

Step-by-step explanation:

The formula to find the circumference is 2πr (r : radius)

if the circumference is 30π the the radius is = 15

to find the area we use the following formula :

π*r^2

r = 15 and π is given as 3.14

(3.14)*15^2 = 706.50 mm^2

Answer:

4.44 cm²

Step-by-step explanation:

If the diagram attached below is required to complete the question,

Applying,

Area of the shaded segment(A) = Area of the sector- area of the triangle

A = (πr²∅/360)-(r²sin∅/)2................ Equation 1

Where r = radius of the circle, ∅ = angle at the center of the circle,π = pie

From the question,

Given: r = 5.4 cm, ∅ = 72°

Constant: π = 3.14

Substitute these values into equation 1

A = (3.14×5.4²×72/360)-(5.4²/2×sin72)

A = 18.31-13.87

A = 4.44 cm²

Answer: The answer is 96 minutes (or 1 hr 36 minutes)

Step-by-step explanation:

Since it takes George 16 minutes to sew one pillowcase, it would take him 96 minutes/1 hr 36 minutes to sew 6 pillowcases (16x6 or 16+16+16+16+16+16/6+6+6+6+6+6+6+6+6+6+6+6+6+6+6+6)

Answer:

sin x° = opposite ÷ hypotenuse

Step-by-step explanation:

Cosine is represented by the expression adjacent ÷ opposite and sine is represented by opposite ÷ hypotenuse. Only the fourth option lines up with the functions defined above.

If you are having trouble remembering the ratios for each trig function, you can use the acronym SohCahToa. This stands for:

S - sine

o - opposite

h- hypotenuse

C - cosine

a - adjacent

h - hypotenuse

T - tangent

o - opposite

a - adjacent

Answer:

11

Step-by-step explanation:

sqrt(121)

What number times itself gives 121

11*11 = 121

-11 * -11 = 121

Answer:

the square root of 121 is 11

which is the second option

Answer:

The graph of a tangent function is defined as the ratio if the opposite side of the adjacent side of any angle, specifically a right-angled triangle.

Answer:

[tex]\frac{15+6}{10-3}[/tex]

Step-by-step explanation:

Sum of 15 and 6 = 15 + 6

Difference of 10 and 3 = 10 - 3

So, the expression is

[tex]\frac {15 + 6}{10-3}[/tex]

This is the required expression.

Hi there!

[tex]\large\boxed{\text{gradient = -2}}[/tex]

Recall the equation:

y = mx + b, where:

m = slope, or gradient of a line

Rewrite this expression into the above format:

3y + 6x = 12

Isolate y by subtracting 6x from both sides of the equal sign:

3y + 6x - 6x = 0x -6x + 12

3y = -6x + 12

Divide all terms by 3:

y = -2x + 4

Thus, the gradient is -2.

Answer:

≈ 30 times

Step-by-step explanation:

The Cubs are projected to win 38 games next season and this is a 22.6% increase from past season.

Step 1 : Let's find 22.6% of 38.

= 8.588

Step 2 : Now, since we increased by this, we subtract.

38 - 8.588 = 29. 412

Of course you can't win only part of a game, so I'm going to say they won 30 times, because a little extra win never hurt anybody. :)

Hope this helps, please mark brainliest!

Step-by-step explanation:

Volume is the measure of the capacity that an object holds. For example, if a cup can hold 100 ml of water up to the brim, its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object or solid shape.

Answer:

the amount of space that a substance or object occupies.

basically the volume of a container, like space in a container.

Answer:

Answer:

To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator.

When the denominators are not the same, we must manipulate them so that they become the same. In other words, you must find a common denominator.

Answer:

-3

Step-by-step explanation:

g(1) = -3x² + x - 1

      = -3([tex]1^{2}[/tex]) + 1 -1

      = -3(1) + 1 - 1

      = -3 +1 -1

g(1) = -3

Just put the 1 everywhere you see an x.

Answer:

A. w+2

Step-by-step explanation:

(w²+2w)/ w =

w(w+2)/w = w+2

Answer:

a) w+2

Step-by-step explanation:

A=w^2+2w

width is w

let's consider length is x

area=length×width

so

[tex] {w}^{2} + 2w = xw[/tex]

[tex]x = \frac{ {w}^{2} + 2w}{w} = w + 2[/tex]

Answer:

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides of the equation

-3x = 21

divide both sides by -3

x = -7

---------------------

-4(y - 2) = 12

distribute the -4 to everything in the parentheses

-4y + 8 = 12

subtract 8 from both sides of the equation

-4y = 4

divide both sides of the equation by -4

y = -1
