Answer:

2.88 pi or approximately 9.0432 cm^2

Step-by-step explanation:

The area of a semicircle is 1/2 the area of a circle

A = 1/2 pi r^2

A = 1/2 pi ( 2.4)^2

A = 2.88 pi cm^2

If we use 3.14 as an approximation for pi

A = 2.88 * 3.14

A =9.0432 cm^2

the cost to rent a hall for school functions is 60$ per hour. write an expression for the cost of renting the hall for h hours.
Firlakuza [10]
The expression for the amount of time rented would be:
C=60(h), I choose this expression because C would stand for cost, 60 for the amount per hour, and h for the piece of expression being given. Now when you need to find the amount per hour, the brackets means to times; so you'd plug in the hour needed to be found in h, and times 60 by the hour.

Your table should look like this :
COST PER HOUR            |            HOURS            |            COST
$60                                    |                 2                  |         $60 x 2 = $120
$60                                    |                 6                  |         $60 x 6 = $360
$60                                    |                 8                  |         $60 x 8 = $480
$60                                    |                10                 |         $60 x 10 = $600

Find the missing side. Round your answer to the nearest tenth.
Sergeu [11.5K]

Answer:

<h3>5.4 </h3>

Step-by-step explanation:

ABC is a right angle triangle.

Therefore,

cos \: (75) =  \frac{ab}{ac}

Plug the values

cos \: (75) =  \frac{x}{21}

Apply cross product property

x = 21 \times cos(75)

Calculate

x = 5.435

After rounding to the nearest tenth, the answer will be:

x = 5.4

Hope this helps...

Best regards!!

Given that (8,-1) is on the graph of f(x), find
Nikolay [14]

Answer:

(-12, -1)

Step-by-step explanation:

(8, -1) => (-2/3x, f(-2/3x))

therefore

-2/3x = 8

x = 8 *-3/2

x = -12

f(-2/3x) = -1

therefore, the corresponding point is:

(-12,-1)

How many integers between 1-100 are divisible by 3?
katrin [286]
You can state the qurstion in an other way
how many integers between 1-100 has 3 in their prime compostion or how many many numbers can be written as 3*a where a is any number
the multiplication table of 3 shows that 3*33=99
which means that highest product below 100 is 3*33
so there are 33 numbers that are divisible by three

Determine the intercepts of the line
Elanso [62]

Answer:

y- (0,2.5) x-(3.5,0)

Step-by-step explanation:

This is because the intercepts of a graph are the points at which a line intersects with a desired axis. So for the Y axis the inercept would be at 2.5 making the y intercept (0,2.5). The same concept is used on the X axis.
