Answer:

7.71

Step-by-step explanation:

The diameter is 3, so the arc length is 180/360 * 3pi or 3pi/2. Now you add the 3 in the base, so it is 3pi/2 + 3 or approximately 7.71 (I used a calculator for that).

Cate wants to buy calzones and sodas for her friends she finds that when she buys two calzones and three sodas she pays $13 when
IceJOKER [234]

Answer:

The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)

Step-by-step explanation:

Let c be the prize of calazone

Let s be the prize of soda

She buys two calzones and three sodas she pays $13

So, 2c+3s=13

She buys three calzones and two sodas she pays $17

So, 3c+2s=17

Plot the equations on graph

2c+3s=13 --- Green

3c+2s=17 --- Blue

Intersection point will give the intersection point

So,(c,s)=(5,1)

So, Option c is correct

The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)

Which expression is equivalent to 4^-5 • 3^-5 ?
valkas [14]

The expression equivalent to 4^-5 • 3^-5  is 12^-5

<h3>What are equivalent expressions?</h3>

Equivalent expressions are simply known as expressions with the same solution but different arrangement.

Given the index expressions;

4^-5 • 3^-5

Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.

This can be written as;

4(3) ^ -5

expand the bracket

12^-5

Thus, the expression equivalent to 4^-5 • 3^-5  is 12^-5
