What is the difference between the 15th square number and the 3rd square number?

Answer:

100-25pi m

Step-by-step explanation:

Let us subtract the circles area from the square

First, let us find the area of the square:

Base x height =

10m x 10m = 100m

Now, the circle:

pi x radius ^2 =

pi x (10/2)^2 =

pi x 5^2=

25 pi

Therefore, the shaded area is 100-25pi m. You can also simplify it further by plugging in the 3.14... value into pi.

I hope this helps! :)

Answer:

8x + 5

Step-by-step explanation:

5 * (2x+1) = 10x +5

10x + 5 -2x

8x + 5

Answer: y = 6/5

Step-by-step explanation:

Answer:

Unless I am an idiot here (think I am) it is AE s the length between A and E, so it is 8

Step-by-step explanation:

Every side of the square is 16.

A to E is half of a side of the square, not a full side.

So you divide 16 by 2, getting 8.

Answer:

C

Step-by-step explanation:

So they bought 2 sneakers. A pair of sneakers cost $6.49. Multiply that by 2, and you get $12.98.

Then they bought a pair of flip flops. So one pair is $0.99. Add that to the $12.98 you got and now you have $13.97.

They also got a pair of flats. One pair is $7.19, so add that to your $13.97 and you now have $21.16.

They also have to pay $1.75 tax, meaning you add that to the $21.16 you have which makes $22.91 total.

But they said how much change they would get from $30 so we're not done yet. So subtract $22.91 from $30 and your answer will be $7.09 which is C.

Answer:

C

Step-by-step explanation:

Because 7.5 is a positive and that is the slope and -2 is a negative and that is the y intercept.

Answer:

5x+3

Step-by-step explanation:

Rewrite the expression to  20x^2-3x-9/4x-3

Factor 20x^2+12x-15x-9/4x-3

Factor 4x*5x+3-3(5x+3)/4x-3

Factor (5x+3)*(4x-3)/4x-3

Solution then becomes 5x+3 as stated above

Answer:

It is only C

Step-by-step explanation:

The only answer for this is C

The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

The arc length is defined as the interspace between the two points along a section of a curve.

Here,  we know that,

angle = arc length / radius    ............(i)

If  arc length / radius = 1   ............(ii)

then from eq. (i) and (ii), we get

angle = 1

θ = 1

Thus, The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

Answer:

The inverse of this function is a parabola that has been rotated 90 degrees clockwise, with it's vertex at point 1, 0.

So it's domain is x ≥ 1

And it's range is y ≥ -2

Step-by-step explanation:

Given:

f(x) = (x + 2)² - 1

First we find the inverse:

x = (f(x) + 2)² - 1

x - 1 = (f(x) + 2)²

√(x - 1) = f(x) + 2

f(x) =  -2 ± √(x - 1)

Answer:

m=-2 b=0

Step-by-step explanation:

first, in order to understand anything, you gotta know what y=mx+b means :)

first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.

so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.

so if we use y=mx+b, we can just substitute the numbers.

which would be, y= -2.

Answer:

Option B

Step-by-step explanation:

Perimeter of the given figure = Sum of measures of all sides

                                                = AB + BC + CA

Since, AB = BC = 9 cm (Radii)

CA = Length of arc CA which is the quarter of the circumference of a circle with radius 9 cm

CA = [tex]\frac{1}{4}(\text{Circumference of the circle})[/tex]

      = [tex]\frac{1}{4}(2\pi r)[/tex]

      = [tex]\frac{1}{2}(\pi )(9)[/tex]

      = 14.14 cm

Now perimeter of the shape = 9 + 9 + 14.14

                                                = 32.14 cm

                                                ≈ 32 cm

Therefore, Option B will be the correct option.

Answer:

35/50

Step-by-step explanation:

Here we will show you how to calculate 3/5 divided by 7/10. We will give you the answer in fraction form and in decimal form.

Here is 3/5 divided by 7/10 displayed

3/5 ÷ 7/10

The numbers in 3/5 divided by 7/10 are labeled below:

3 = dividend numerator

5 = dividend denominator

7 = divisor numerator

10 = divisor denominator

To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.

Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:

3 x 10/5 x 7 = 30/35

Thus, the answer to 3/5 divided by 7/10 in fraction form is:

30/50

Answer:

a) £32 and £16

b) £12 and £36

Step-by-step explanation:

It is given that:

Amount to divide = £ 48

a) 2 : 1

Let,

x be the times of share.

2x + x = 48

3x = 48

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{48}{3}\\x=16[/tex]

Thus,

2x = 2(16) = £32

x = £16

b) 1 : 3

x+3x=48

4x=48

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{48}{4}\\x=12[/tex]

x = £12

3x = 3(12) = £36

Therefore,

a) £32 and £16

b) £12 and £36

Answer:

Step-by-step explanation:

4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.

4 and 3 are supplementary angles (they both add up to 180°).

4 and 1 are vertically opposite angles and are equal to each other.

From the above explanations, only 4 and 8 are corresponding angles.
