The area would be approximately 153.94.

The area of a circle is pie multiplied by r^2. 

So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.

A=3.14(7)^2

What is 5 7/8 minus 11/4
aksik [14]
First you need to simplify it so

5 7/8 = 5x8=40  40+7=47 so at the moment you have 47/8
then do
11/4 is fine so find the common denominator
in this case its 8 so   4x2=8 and then 11x2=22 so you have 47/8-22/8
which = 25/8 then you simplify and you get <em><u>3 1/8</u></em>

Let Angle w be an acute angle. Use a calculator to approximate the me
serious [3.7K]

Answer:

<h2>49.5°</h2>

Step-by-step explanation:

Given the trigonometry function as shown sin W = 0.79, to get W, the following steps must be followed.

Step 1: Take the arcsin of both sides of the equation

sin^{-1}(sinW) =  sin^{-1}0.79\\W = sin^{-1}0.79

Step 2: Use a calculator to get the resulting value of W

W = 49.46^{0}

W = 49.5^{0} (to nearest tenth of a degree)

This gives the acute angle needed.

Note that acute angle are angles that are less than 90°

Adult tickets to a a basketball game cost $5. Student tickets cost $1. A total of $2,757 was collected on the sale of 1,185 tick
Anastaziya [24]

Answer:

Number of Adults Ticket=393

Number Of Students Tickets=792

Step-by-step explanation:

Let 'x' be the Adult's tickets

Let 'y' be the Student's tickets

x+y=1185 (total sold tickets)

5x+y=2757(total cost of tickets)

-(5x+y=2757)x+y=1185

 (-5x-y)- x+y=1185-2757

=-4x+0 = (-1572)

=-4x=(-1572)

x= (-1572)÷-4

=393

=x+y=1185

=393+y=1185

=y=792

So Number of Adults Ticket=393

Number Of Students Tickets=792

Hope it Help
