Answer:

No, she tipped about 18%.

Step-by-step explanation:

How much she tipped:

$25 - $21.18 = $3.82

To find the percentage, you can put this tip over the what she paid for the pizza.

\frac{3.82}{21.18} =0.18=18%%

She only tipped about 18%

Find the volume of a cylinder with radius 8cm and height 10 cm, correct to 2 decimal places.
serious [3.7K]

Answer:

2010.62cm^3

Step-by-step explanation:

The formula for the area of a circle is : \pi *radius^2

To work this out you would first have to work out the area of the circle. You can do this by multiplying pi by 8 squared, this gives you 201.06. This is because in order to calculate the volume you must calculate the area of one face of the shape.

The next step is to multiply 201.06 by 10, this gives you 2010.62.

1) Multiply pi by 8 squared.

\pi*8^2=201.06

2) Multiply 201.06 by 10.

201.06*10=2010.62cm^3

Easy problem for you guys to solve
Zepler [3.9K]

In the ΔIJH, the value of the cosec (I) is 1\frac{9}{56}.

Given ΔIJH the length of the hypotenuse is 65,  the length of the base is 33, and the length of the opposite side is 56.

We have to find the value of the cosec (I).

A function of an arc or angle that is most easily represented in terms of the ratios of pairs of sides of a right-angled triangle, such as the sine, cosine, tangent, cotangent, secant, or cosecant.

We know cosec (I) = hypotenuse / opposite side

Substitute the values

cosec (I) = 65/56

              = 1\frac{9}{56}

Hence the value of cosec (I) is 1\frac{9}{56}.

Whats the equation of a line with slope 3/5 that passes through the point (15,8)
Elden [556K]

Answer:

y=3/5x-1

Step-by-step explanation:

The formula you need to find this would be

(y-y1)=m(x-x1)

The y1 is your y point.

The x1 is your x point.

m is your slope.

Start by plugging in your numbers that they provide you.

(y-8)=3/5(x-15)

Now you need to distribute the slope to the terms inside the parenthesis next to it.

3/5(x)=3/5x

3/5(-15)= -9       Now you put those back into the equation.

(y-8)=3/5x-9

At this point you can get rid of the parenthesis around the y-8 since it is basically saying to take the term times 1.

To get y alone we not need to add 8 to both sides.

y-8=3/5x-9

+8          +8

y=3/5x-1
