This says is supposed to be 20 characters long. The actual question is the one in the picture. f(1)=?

Answer:

Step-by-step explanation:

Number of laps run by Runner A = x

Number of laps run by Runner B = y

Runner B ran 6 more than twice as many laps as Runner A.

b = 6 + 2a

Together they ran a total of 30 laps.

a + b = 30

Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A.

Part B: How many laps did Runner A run?

a + b = 30

b = 6 + 2a

Hence:

a + 6 + 2a = 30

3a = 30 - 6

3a = 27

a = 27/3

a = 9 laps

Part C: How many laps did Runner B run?

a + b = 30

b = 30 -9

b = 21 laps

Step-by-step explanation:

The LCD here is the smallest integer evenly divisible by both 7 and 3.  That number would be 21.  Then:

1/7 and 2/3 become 3/21 and 14/21.

I'm trying to solve this problem but there's something wrong

What's the radius of one ball?

Answer:

198

Step-by-step explanation:

rectangular side (9,3)

9x3=27

27x2= 54 (because there's rectangular sides)

Square end(6,3)

6x3=18

18x2=36(two square sides)

top&bottom sides

6x9=54

54xsquared2=108(two sides)

add all together

54+36+108=198cm(squared)

Answer:

The area of the shaded region is about 38.1 square centimeters.

Step-by-step explanation:

We want to find the area of the shaded region.

To do so, we can first find the area of the sector and then subtract the area of the triangle from the sector.

The given circle has a radius of 6 cm.

And the given sector has a central angle of 150°.

The area for a sector is given by the formula:

[tex]\displaystyle A=\pi r^2\cdot \frac{\theta}{360^\circ}[/tex]

In this case, r = 6 and θ = 150°. Hence, the area of the sector is:

[tex]\displaystyle \begin{aligned}A&=\pi(6)^2\cdot \frac{150}{360}\\ &=36\pi\cdot \frac{5}{12}\\&=3\pi \cdot 5\\&=15\pi \text{ cm}^2\end{aligned}[/tex]

Now, we can find the area of the triangle. We can use an alternative formula:

[tex]\displaystyle A=\frac{1}{2}ab\sin(C)[/tex]

Where a and b are the side lengths, and C is the angle between them.

Both side lengths of the triangle are the radii of the circle. So, both side lengths are 6.

And the angle C is 150°. Hence, the area of the triangle is:

[tex]\displaystyle A=\frac{1}{2}(6)(6)\sin(150)=18\sin(150)[/tex]

The area of the shaded region is equivalent to the sector minus the triangle:

[tex]A_{\text{shaded}}=A_{\text{sector}}-A_{\text{triangle}}[/tex]

Therefore:

[tex]A_{\text{shaded}}=15\pi -18\sin(150)[/tex]

Use a calculator:

[tex]A_{\text{shaded}}=38.1238...\approx 38.1\text{ cm}^2[/tex]

The area of the shaded region is about 38.1 square centimeters.

Answer:

3√5

Step-by-step explanation:

The largest perfect square of the factors of 45 is 9. We can therefore convert √45 like this:

√9 × 5

Next, we separate the numbers inside the √ as such:

√9 × √5

√9 is a perfect square that equals 3. We can therefore put 3 outside the radical and get the final answer to square root of 45 in simplest radical form as follows:

3√5

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 , then

y = 6x + c ← is the partial equation

To find c substitute (2, 19) into the partial equation

19 = 12 + c ⇒ c = 19 - 12 = 7

y = 6x + 7 → B

Answer:

B. y = 6x + 7

Step-by-step explanation:

Since the equation in slope: intercept form, y = mx + b, identify the slope of the line as the coefficient next to the variable x

y = 6x + 7, m = 6

Use the given slope and point to substitute into the point-slope formula

[tex]y - y1 = m (x-x1)[/tex]

Slope: intercept form:

y = 6x + 7

Point-slope form:

y - 19 = 6 (x - 2)

P = 6+6+5x-3 + 5x -3 = 10x+6

A = 6(5x-3) = 30x -18

Answer:

30x-18 is the area

the perimeter is 10x+6

Step-by-step explanation:

not enough info to solve for x, but we can still have a variable

6(5x-3)

distribute

6(5x)-6(3)

30x-18 is the area

the perimeter is 10x+6

Answer:

12.42 units

Step by step explanation:

Given,

length of the radius = 2 units

Therefore, arc length of the complete circle = 2 × 3.14 × 2 units = 12.56 units

Therefore, arc length of the partial circle = 3/4 × 12.56 units

= 12.42 units
