Shandra is on vacation and wants to buy souvenirs for at least eight friends.
A postcard book costs $2.50 and a
magnet costs $4.00. She can spend
up to $30 altogether. Write a system
of inequalities to represent the situation.

Step-by-step explanation:

Let p be the number of posters and m be number of magnets.

Cost of a postcard book = $2.50

Cost of a magnet = $4.00

Shandra wants to buy them for at least eight friends.

So,

She can spend  up to $30 altogether.

So,

Hence, the system  of inequalities to represent the situation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

2: 10
