In a different plan forarea codes the first digit is 1 through 6 the second digit is either 5 6 7 or 8 the third digit could be any number except 5 with this plan how many ways is area code possible

216

Step-by-step explanation:

There are 6 options for the first digit.

There are 4 options for the second digit.

There are 9 options for the third digit.

The total number of combinations is 6 × 4 × 9 = 216.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
