A tennis supply store pays a wholesaler $90 for a tennis racquet and marks it up by 60%.
What do they charge for the tennis racquet?

Answer:

C= 2 radians.

Step-by-step explanation

Length of arc = r C where r = the radius and C is the angle in radians.

Area of the sector = 1/2 r^2 C

So we have:

30 = rC  and

900 = 1/2 r^2 C

From the first equation we have  r = 30/C so substituting for r:

900 = 1/2 (30/C)^2 * C

900 = 0.50 (900/C^2) * C

900 =  450/C

C= 2 radians.

Answer:

no 6^2 + 8^2 ≠ 12^2 so this is not a right triangle

Step-by-step explanation:

The Pythagorean theorem  tells you if you have a right triangle

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + 8^2 = 12^2

36+64 = 144

100 = 144

This is not true so this is not a right triangle

Answer:

[tex]t \approx 50.4\,min[/tex]

Step-by-step explanation:

The time constant of the element X is:

[tex]\tau = \frac{13\,min}{\ln 2}[/tex]

[tex]\tau = 18.755\,min[/tex]

The decay function has the following form:

[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]

[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]

[tex]t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)[/tex]

[tex]t \approx 50.4\,min[/tex]

Step-by-step explanation:

Answer:

111 boxes

Step-by-step explanation:

He bought 223 feet of wood

Each box will take 2 feet

To determine the total number of box he'll make from 223,

1 box = 2 feet of wood

X box = 223 feet of wood

X = (223 × 1) / 2

X = 111.5 box approximately 112 boxes

But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left

Answer:

4,950

Step-by-step explanation:

5 or up rounds up 4 or down rounds down therefore 4,952 rounds to 4,950

Answer:

4,950

Step-by-step explanation:

Answer:

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]

Step-by-step explanation:

Slope intercept form is y = mx + b, so you rewrite it to equal y.

ax + by = c

by = c - ax

y = (c - ax) / b

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]

In the image, all the lines overlap. This proves that all the equations are equal to each other.

9a^2 + b^2

Step-by-step explanation:

(3a + b)^2

9a^2 + b^2

Answer:

64

Step-by-step explanation:

step one would be to divide 140 by 56 and once you do that you would get 2.5 so then you would divide 160 by 2.5 to get 64.

The Answer Is 9

Step-by-step explanation:

0.5(3)(6)

1.5(6)

9

Answer:

9

Step-by-step explanation:

I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

Answer:

x = 6 m

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 60, h = 8, a = 9 and b = x , thus

[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is

4(9 + x) = 60 ( divide both sides by 4 )

9 + x = 15 ( subtract 9 from both sides )

x = 6 m

Answer:

A. [tex]11 + 3\frac{5}{8}[/tex]

Step-by-step explanation:

Subtracting a positive number is like adding a negative number, as in you move to the left on a number line. A negative number is the opposite of the positive, so you move to the right instead, which is equivalent to adding.

Make sure there are parenthesis around the negative number, otherwise, you might be seeing one minus sign as two!

Answer: 72 km / hour

Step-by-step explanation:

Answer:

72 km/hr

Step-by-step explanation:

First, convert from meters to kilometers. 20 meters is 0.02 kilometers.

Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!

Answer:

(MAD) mean absolute deviation: 114.2

Step-by-step explanation:

Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164

164 - 62 = 102

164 - 71 = 93

164 - 83 = 81

164 - 110 = 54

164 - 501 = 337

164 - 94 = 70

164 - 227 = 63

Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 =  114.2

Answer:

Step-by-step explanation:

First, add all the numbers and count the total amount of numbers.

Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.

Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)

Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.

Then, you have the M.A,D ( Mean Absolute Deviation )

assuming b is the underscript of log, the formula is log _b_3=-8.

the formula for log is usually log_b_x=n, and to convert it to exponential would be the same as b^n=x

just fill in the numbers, b is still b, and -8 will be the in place of n, equal to 3.

b^-8=3

Answer:

180°

Step-by-step explanation:

A polygon that has 32 sides is called a triacontadigon or a triacontakaidigon.

The angles of a triacontadigon add up to 5760°.

5760÷32=180°

So the right answer is 21/16 cubic centimetres
